List of Transformers film series characters

The following is a list of characters featured in the Transformers film series, distributed by Paramount Pictures. Over 194 characters appeared.

Autobots

In the four films, 28 Autobots have appeared in the series. Most of them were members of NEST. By the end of Dark of the Moon, nine Autobots remained on Earth. But after five years, Cemetery Wind and Lockdown eliminate most of them. By the end of Age of Extinction, nine Autobots remained on Earth, while Optimus leaves Earth.

Optimus Prime

Peter Cullen voices Optimus Prime, the leader of the Autobots, keeper of the Matrix of Leadership and the narrator of the film series. He comes to Earth to destroy the AllSpark in order to end the war. Don Murphy decided after discussions with fans on his website that they wanted the surviving voices from the original 1980s cartoon series, The Transformers. Cullen described reprising the role as easy as "slipping into an old pair of very comfortable shoes that you haven't worn for a while", and was grateful to the fans for wanting him back. His performance consisted of much improvisation with Bay, and portraying the traditional heroism of the character as well as bringing a sense of humor. Bay told the animators to seek inspiration from Liam Neeson to inspire Optimus's body language. Optimus transforms into a 1997 red and blue Peterbilt 379 semi-trailer truck built by truck designer Dave Porter of Wright City, MO. The selection of the Peterbilt, a more aggressive truck compared to the original flat-nosed truck from the animated series was also made as a nod to Spielberg's film Duel. The original cab over design was rejected because that would only transform into a twenty-feet tall model of the character, whereas the filmmakers wanted him to stand thirty feet tall. Optimus has red flame artwork on his blue body. This was a compromise between Hasbro, who wanted to retain the character's iconic red chest, and Bay, who felt red alone would not photograph well. Hasbro had previously rejected designs of Optimus which were too blue. Optimus' head was built on set as a prop. In the first film, Optimus Prime arrives on earth with Ratchet, Ironhide, and Jazz trying to find the AllSpark. In the final battle at Mission City, he kills the Decepticon Bonecrusher and battles Megatron. Optimus is unable to defeat Megatron, but is saved when Sam pushes the AllSpark into the Decepticon's chest, killing him and destroying the cube. As a result, Cybertron can no longer be restored. Afterwards, Optimus and the other Autobots form an alliance with the humans.

In Revenge of the Fallen, conceptual essays were made in an attempt to use his classic trailer for his power up mode, but this was ultimately dropped in favour of the incorporation of Jetfire's parts. Cullen recorded a voiceover for the opening scene in August 2008, but began the majority of voice work in November. Optimus is killed by Megatron after a battle with him, Starscream and Grindor. Near the end of the film, he is later revived by Sam with the Matrix of Leadership and is fused with Jetfire, making him more powerful. Optimus Prime then faces The Fallen and Megatron. After a vicious fight, Optimus severely wounds Megatron and kills the Fallen. Originally, a cameo was written for Cullen, but it was not included in the final cut of the film.

In Dark of the Moon, Optimus Prime revives Sentinel Prime using the Matrix of Leadership, though Sentinel later betrays the Autobots and joins the Decepticons. During the battle in Chicago, Optimus kills Sentinel Prime (avenging Ironhide's death) along with dozens of other Decepticons, including the Driller, Shockwave, and finally Megatron. Optimus has added a trailer similar to his Generation 1 counterpart, and has been redesigned to look more heroic. The trailer contains enhanced weapons, a shield and a flight gear. Optimus loses his arm to Sentinel Prime at the film's climax.

In Age of Extinction, Optimus Prime now transforms into a rusty 1973 Marmon semi cab-over truck and later on a new alternate mode in a blue and red Western Star 4900 Custom Phantom semi-truck. In the film, despite his right arm repaired at the end of Dark of the Moon, Optimus gets a new look with two truck modes. However, he is being hunted by a bounty hunter, Lockdown, who is working for the Creators to bring him to them. Soon in the battle of Hong Kong, Optimus tames the four Legendary warriors and ride Grimlock to fight Galvatron (who is actually Megatron reincarnated) and his new army of man made Transformers. After defeating Galvatron's army, he successfully kills Lockdown and Harold Attinger (avenging the deaths of Ratchet, Leadfoot and Lucas, and possibly Sideswipe, Dino, Roadbuster and Topspin). He then sets the Knights free and ask his fellow Autobots to protect Cade and his family before bringing the Seed to space and goes after the Creators.

Optimus Prime has a vast array of weaponry. This includes a pair of Energon swords (usually retractable from his arms, but can also be handheld), a pair of Energon hooks (retractable from his wrists), a handheld Ion blaster in the first two films, and a handheld Barrage Cannon in TF3 and TF4. He also has a handheld Energon axe stored in his trailer in Dark of the Moon. In the fourth film, Optimus now carries a fusion shotgun he got from finally killing Megatron and shooting Sentinel Prime in the head twice to avenge Ironhide and later takes a large handheld "Sword of Judgement" as a replacement for his energon swords, which he previously lost in his fight with Galvatron.

Bumblebee

Mark Ryan voices Bumblebee in the end of the first film, when he regains his voice after the final battle. He serves as an Autobot scout, and later Optimus' second-in-command after Ratchet's death in the fourth film, and Sam Witwicky's guardian and best friend in the first three films, and later Tessa and Shane's best friend. For most of the first film's duration, Bumblebee communicates with radio soundbites because of his damaged vocal processor, but his throat begins healing after Ratchet fires a regenerative laser when they meet again on Earth: this was not clarified on screen, and Orci feels that Bumblebee being healed by touching the AllSpark is also a valid explanation.

Bumblebee transformed into a 1975-77 style Chevrolet Camaro, and upgrades into the 2006 model. In reference to his original form, the Beetle is parked next to Bumblebee when Sam is buying him. The modern Camaro was chosen for its friendly appearance, while the old model was chosen to show that Sam's father could only buy him the cheapest car he could find. He is also a red repaint of Cliffjumper, an Autobot who appeared in the 2007 toyline and Transformers: The Reign of Starscream, and later shot and killed by Starscream in the back.

For Revenge of the Fallen, despite being repaired at the end of the 2007 film, Bumblebee's voice still uses radio soundbites to communicate. Sam tells Mikaela that Bumblebee's "playing it up". Mark Ryan reportedly reprised his role as the voice for Bumblebee, but ultimately no spoken lines by the character were included in the finished film. The filmmakers updated Bumblebee's previous appearance as the 2006 Camaro Concept based on the Super Sport version of the 2010 Ed Welburn, vice president of GM Global Design, said the redesigned car emphasized Bumblebee as becoming stronger after having his severed legs reattached in the 2007 film, with the new and showing him as a sturdier character.

For Dark of the Moon, Bumblebee has gone through some changes. His vehicle mode is now a Chevrolet Camaro 2011, and features a new body kit and paint job.

For Age of Extinction, Bumblebee is now a modified vintage 1967 Chevrolet Camaro SS, and later on a 2014 Chevrolet Camaro concept. He appears after Optimus calls all the Autobots and has a rivalry with Drift (because Drift believes Bumblebee is too childish). He later aids Hound in a battle and rides Strafe and aid Optimus with the battle with Lockdown and eventually assuming temporary leadership of the Autobots during Optimus's absence.

Ironhide

Jess Harnell voices Ironhide, the Autobots' cantankerous weapons specialist who transforms into a modified black 2006 GMC TopKick C4500 medium-duty truck. He has both cannons on his arms. Peter Cullen also voiced Ironhide on television and auditioned to reprise the role. When Harnell was voicing the character on set, he used a Southern accent as Cullen did. In the two sequels, Ironhide seems to replace Jazz as Second-In-Command.

He is later murdered by Sentinel Prime in Dark of the Moon, when Sentinel betrays the Autobots. Later in the battle of Chicago, his death is avenged when Optimus kills Sentinel.

In Age of Extinction, a picture of Ironhide appears with a red X indicating his death.

Jazz

Darius McCrary voices Jazz, a lieutenant who develops a fondness for urban culture and Optimus Prime's second in command. McCrary said he was honored to follow in the footsteps of Scatman Crothers, who voiced Jazz on The Transformers. "When I was actually [recording], I really did feel Scatman's presence," he said. Mark Ryan had tried out numerous voices for Jazz, including a Sean Connery impersonation, before McCrary was cast. Jazz transforms into a modified silver Pontiac Solstice Custom Hardtop GXP, a car the director felt was too small, but he decided not to argue with GM. Hasbro felt it was still a "cool sports car" reminiscent of his original Porsche 935 form.

He is later killed by Megatron during the battle in Mission City. The screenwriters chose to kill off Jazz as they felt he was the most likable character after Optimus and Bumblebee, although they did not have time to make it effective due to budget constraints. Jazz is later avenged when Sam killed Magatron by pushing the Allspark in his spark chamber and when Optimus Prime finally killed Megatron with his Energon axe by ripping his head off in Dark of the Moon.

Despite his death in the 2007 film, he appears as downloadable content for the video game based on Revenge of the Fallen for campaign and multiplayer mode. He also appears in the toylines for Revenge of the Fallen and Dark of the Moon, and also a repaint of Smokescreen, who is killed by Shockwave in the Rising Storm comics.

Ratchet

Robert Foxworth voices Ratchet, the Autobots' medical officer who transforms into a Los Angeles Fire Department search and rescue 2004 Hummer H2. The writers had wanted to keep his original ambulance form, but the producers wanted something else. Hasbro did not mind if the character was either an ambulance or a fire apparatus.

For both Dark of the Moon and Transformers: The Ride, Ratchet had some changes done to his vehicle mode, which was painted green and white (red and white for his G1 color in the toyline). He also seemed to be the second-in-command alongside Sideswipe after Ironhide's death.

In Age of Extinction, Ratchet was found by Cemetery Wind agents aboard a steamship. After wounding him and loses his right leg, he refuses to tell Lockdown where Optimus is, but later Lockdown rips out his spark killing him, and taken to KSI, melting his head to build remote controlled Transformers. His death affected Optimus the most, knowing that he lost a good friend, even to the point of Optimus wanting to kill the humans responsible for Ratchet's death. He is later avenged when Optimus killed Harold Attinger and Lockdown at the climax of the film.

Sideswipe

André Sogliuzzo, later James Remar, voices Sideswipe, the Autobots' combat instructor who transforms into a silver Chevrolet Corvette Stingray concept. His arms sport detachable sword-like blades, and having wheels for feet, he moves around skating. For his development of Revenge of the Fallen, its creators were inspired by roller derby players. Sideswipe was originally scripted to be a Lamborghini as he was in G1, but Bay ultimately decided to change him into the Stingray.

For both Dark of the Moon, Sideswipe's vehicle mode is upgraded into a convertible. He also seemed to be Optimus Prime's second in command alongside Ratchet after Ironhide's death.

Sideswipe also appears in Transformers: The Game.

It is unknown what happen to Sideswipe as he doesn't appeared in Age of Extinction. It is possible that he was hunted down and killed by Cemetery Wind and Lockdown or hiding from around the world in place.

Jolt

Jolt is a technician Autobot armed with a pair of electric whips who transforms into a blue Chevrolet Volt. He was a last-minute addition to the cast as General Motors wanted to promote the Volt. The writers had already wanted to include the car in the script before the Writers Guild strike, so they had to work out a character that would fit well within the Autobot team afterwards and convince Bay to approve the addition. Welburn was pleased the Volt's character was christened Jolt by the filmmakers, as it reflected that car's design character.

He appears in Revenge of the Fallen, being surrounded by NEST forces along with Sideswipe, Ratchet, and Ironhide. He also fought in the battle in Egypt. After Jetfire sacrificed his parts to Optimus, he used his whips to fuse Jetfire's parts onto Optimus.

He does not return in Dark of the Moon as in a prequel comic he is killed by Shockwave and also appeared in the toyline of Dark of the Moon and Age of Extinction.

Skids

Tom Kenny voices Skids, an Autobot messenger and Mudflap's twin who transforms into a front white/pink Ice Cream truck, and later a green Chevrolet Beat. He has an oversized right arm. In Dark of the Moon, Skids now transforms into a black and light green Chevrolet Spark. However, he made a cameo in the film, and never seen again, but his robot mode appeared in the toyline. In the novel and comic book adaptations of the film, he is killed by Sentinel Prime, after killing Ironhide.

Mudflap

Reno Wilson voices Mudflap, an Autobot infiltrator and Skids' twin who transforms into a back white/pink Ice Cream truck, and later a red Chevrolet Trax. Like Skids, he has an oversized left arm. In Dark of the Moon, Mudflap now transforms into a black and orange Chevrolet Spark. However, he made a cameo in the film, and never seen again, but his robot mode appeared in the toyline. In the novel and comic book adaptations of the film, he and Skids are killed by Sentinel Prime.

Arcee

Grey DeLisle voices Arcee, a female Autobot who transforms into a pink Ducati 848. Arcee was initially meant to appear in the 2007 film as a robot that transformed from a single bike, but was ultimately dropped from it due to concerns of her being too small compared to the other bots, and the fact that the writers felt there was not enough time to explain her gender, despite her and several other female Transformers appearing in the 2007 film's toyline and tie-in comics. Whether to explain robotic gender or not was something the writers were unsure about, and it remained undecided until post-production, with the issue eventually remaining unaddressed in the finished film. She was then replaced by Ironhide. Arcee's holographic riders are played by Erin Naas.

Arcee and her sisters, Chormia and Elita-One, are deployed to chase after Sideways, before Sideswipe kills him. Later in the battle of Egypt, she and Elita-One are shot and killed. During development, the three bikes were first conceived to be able to combine into a single robot, and this ability can still be seen in the film's novelization.

In Age of Extinction, a picture of Arcee appears with a red X indicating her death.

Chromia

Grey DeLisle voices Chromia, one of Arcee's sisters who transforms into a blue 2008 Suzuki B-King. In the battle of Egypt, Chormia takes cover after her sisters are shown shot and killed.

Elita-One

Grey DeLisle voices Elita-One, one of Arcee's sisters who transforms into a purple MV Agusta F4 R312. During the battle of Egypt, she and Arceee are shot and killed. Despite her death, between the second and third films (in the comics), Elita is crushed and killed by Shockwave, leaving her sisters alive.

Jetfire

Mark Ryan voices Jetfire, a Cockney accented Seeker and former Decepticon who transforms into a Lockheed SR-71 Blackbird. His wounds and age have made him choose to fight on the side of the Autobots. The writers wanted a geriatric robot, and during scripting they gave Jetfire that personality. He creaks, does not transform well, falls apart, and is said to be running out of energon. Also, he walks with a cane, which doubles as a battle axe. He later sacrificed his spark to allow his parts for Optimus Prime to destroy the Fallen.

Ryan, who voiced Bumblebee in the first film, participated in the early production of Dark of the Moon, but his work wasn't ultimately featured in the film.

Wheelie

Tom Kenny voices Wheelie, a Decepticon spy turned Autobot who transforms into a blue radio-controlled toy monster truck and speaks with a Brooklyn accent. Wheelie initially serves the Decepticons just because he is scared of them, but during the 2009 film, upon learning that Jetfire had switched sides, he chooses to do so himself. His left eye was destroyed by Mikaela Banes. He is called "Wheels" in the 2009 film novel.

In Dark of the Moon, despite his left eye being fixed, he lives with Sam Witwicky, Carly Spencer, and Brains whom he becomes friends with. Later in the Battle of Chicago, he and Brains go down inside the Decepticon ship to the river and are not seen again for the rest of the film. It is unknown if Wheelie survived the crash or not, for he is not seen in Age of Extinction.

Brains

Reno Wilson voices Brains, a small and intelligent Decepticon drone turned Autobot who transforms into a Lenovo ThinkPad Edge laptop computer, and he is friends with Wheelie. Later in the battle of Chicago, he and Wheelie sabotage a Decepticon ship and crashed landed in a river. According to the movie prequel comics, he was originally a Decepticon mobile "brain unit" drone that had gained sentience and escaped.

He is the only Autobot to appear in the films, but not in the toyline.

In Age of Extinction, despite his death in Dark of the Moon, Brains is captured by KSI, who lost his right leg and he is used to read and transfer data from fallen Autobots and Decepticons (including Ratchet, Leadfoot, Sentinel Prime, Megatron, possibly Sideswipe, Dino, Roadbuster and Topspin) into the company's new Transformers. When transferring data from Megatron's head, he discovers that his mind is still alive and knew that Megatron would manipulate the humans and claim the Seed for himself. Brains is later rescued by the Autobots during their raid to the KSI headquarters, but is not satisfied because they "didn't kick even a little ass". He later tells them about Galvatron is Megatron reincarnated. He later walks off and happily sniffed some daisies.

Mirage

Francesco Quinn voices Mirage, an Autobot spy who transforms into a red Ferrari 458 Italia and speaks with an Italian accent. He has blades on his arms, and he resembles Bumblebee, with the same body. He was credited as "Dino".

In early concept art for the film, he is named "Rush" and "Enzo". This was Quinn's final role right before his death on August 5, 2011, age 48. Before the release of the film, Dave Wittenberg voices him in the video game of Dark of the Moon. In the junior novelization, (taking Que/Wheeljack's death in the film), Dino/Mirage is executed instead by Soundwave.

He appeared in the toyline of Age of Extinction, a remodel of a ROTF Sideways, with a new head. But, it is unknown what happen to Mirage as he doesn't appeared in Age of Extinction. It is possible that he was hunted down and killed by Cemetery Wind and Lockdown or hiding from around the world in place. While filming Age of Extinction, a 2014 Ferrari 458 Speciale was seen on set in Hong Kong and was rumored to be Mirage. The car didn't appear in the final cut and neither did Mirage.

Wheeljack

George Coe voices Wheeljack, an Autobot scientist who speaks with an Irish accent, whose head design resembles Albert Einstein and transforms into a blue Mercedes-Benz E550. He is an inventor and is seen giving the Autobots weapons and equipment he has created such as a gun for Ironhide, grappling gloves and boomsticks. He is later killed when Soundwave orders his execution; a Decepticon Protoform shoots him in the chest and Barricade finishes him off. Bumblebee kills Soundwave by shooting his head and human soldiers kill Barricade by taking out his eyes, using his boomsticks and shooting at him, avenging his death. He was credited as "Que/Wheeljack".

He was credited as "Que/Wheeljack" in the film's credits. Before the release of the film, Jamie Alcroft voices him in the video game of Dark of the Moon.

In Age of Extinction, a picture of Que/Wheeljack appears with a red X indicating his death and appeared in the toyline, while a poster of Einstein is seen inside Cade's barn.

Sentinel Prime

Leonard Nimoy voices Sentinel Prime, Optimus Prime's predecessor and mentor, the captain of the Ark and an Autobot turned Decepticon who transforms into a red and black Rosenbauer Panther airport crash tender fire truck. His intention to restore Cybertron to its former glory after the war drove him mad, causing him to go against his ideals and side with the Decepticons, eventually becoming as corrupt and vile as they were. After betraying the Autobots and murdering Ironhide, as well as most of the N.E.S.T soldiers, Sentinel sets up a Space Bridge in Chicago, intending to summon Cybertron itself to Earth's atmosphere and repair the planet using Earth's resources and mankind as a workforce. Before activating the bridge, Sentinel betrays Megatron and takes command of the Decepticons for himself. During the final battle, Sentinel battles Optimus in a fierce duel. The elder Prime gets the upper hand and nearly kills his former apprentice, but Megatron, after being goaded into action by Carly Spencer, ambushes Sentinel and badly wounds him. Bumblebee and Ratchet deactivate the Space Bridge and Optimus kills the deceitful Megatron. Seeing his plans in ruins, the weakened Sentinel complains and attempts to justify his actions, but Optimus, claiming Sentinel "betrayed himself", executes his traitorous mentor with Megatron's shotgun, avenging Ironhide and the humans that he killed at the Washington N.E.S.T base.

In Age of Extinction, a picture of Sentinel Prime appears with a red X indicating his death. Later his head made a cameo at KSI, downloading his mind.

Nimoy, who voiced Galvatron in the 1986 movie, was considered for voicing The Fallen in Revenge of the Fallen before the role was given to Tony Todd.

Sentinel Prime was modeled after actor Sean Connery. In early production, Sentinel Prime was known as "Ultra Magnus", and he looks similar to Alpha Trion.

Wreckers

The Wreckers are a trio of Autobots who transforms into NASCAR Sprint Cup Series Chevrolet Impala stock cars as disguises. Two represent Hendrick Motorsports and one represents Earnhardt Ganassi Racing. The Wreckers are mechanics who work with Epps at a NASA base on the Xantium ship. They later take part in the Battle of Chicago, distracting Shockwave to allow the others to escape. They then help Optimus get out of a bad situation and help in the counterattack on Sentinel Prime. After Optimus destroys Megatron and Sentinel, they are present as the surviving Autobots. In January 2011, five months before the film, Bill Fagerbakke, who voiced Bulkhead in Animated, announced that he would voice of the Wreckers, but didn't appear in the final cut of the film.

Roadbuster

Ron Bottitta voices Roadbuster, one of the three Wreckers who transforms into an armored version of the #88 Hendrick Motorsports AMP Energy/National Guard car and speaks with a Scottish accent. He has two missiles on his back.

In early production, Roadbuster was known as "Warpath". His alt. mode was intended as a #24 DuPont-sponsored Chevrolet Impala, but removed as a #88 instead.

It is unknown what happen to Roadbuster as he doesn't appeared in Age of Extinction. It is possible that he was hunted down and killed by Cemetery Wind and Lockdown or hiding from around the world in place.

Leadfoot

John DiMaggio voice Leadfoot, the leader of the Wreckers who transforms into an armored version of the #42 Earnhardt Ganassi Racing Target car and speaks with a Cockney accent. He appears to be overweight as seen by the extra vehicle kibble hanging in front of his body.

In early production, Leadfoot was known as "Flash".

In the toyline, the Human Alliance Leadfoot is partnered with an Autobot dog called Steeljaw.

In Age of Extinction, Leadfoot appears in the video footage, where he was attacked and killed by Cemetery Wind agents. Cade, who hacks a Cemetery Wind's spy drone, shows a footage of his death to the Autobots. Upon learning of his death, Hound seemed the most saddened, taking off his helmet and saluting his fallen friend. Leadfoot is later avenged when Optimus killed Harold Attinger and Lockdown at the climax of the film.

Topspin

Topspin is one of the three Wreckers who transforms into an armored version of the #48 Hendrick Motorsports Lowe's/Kobalt car and appear to have claws on his hands.

In early production, Topspin was known as "Tempest" and "Warpath". In late 2011 of the Dark of the Moon toyline, Topspin has a new black repaint, and known as "Armor Topspin".

It is unknown what happen to Topspin as he doesn't appeared in Age of Extinction. It is possible that he was hunted down and killed by Cemetery Wind and Lockdown or hiding from around the world in place.

Hound

John Goodman voices Hound, an Autobot commando who transforms into a dark green Oshkosh Defense Medium Tactical Vehicle. His robot mode is modeled after a human commando with a beard and bullet which he smokes like a cigar. Hound is the heavy weapons expert of the small group carrying various types of guns with him. After learning of Leadfoot's demise and thanks to Cade hacking into a Cemetery Wind spy drone, Hound seemed the most saddened, taking off his helmet and saluting his fallen friend, bitterly cursing the humans responsible as "savages".

Hound also appears in Transformers: The Game.

Drift

Ken Watanabe voices Drift, an Autobot tactician, a former Decepticon and a Triple Changer who transforms into a black and blue 2013 Bugatti Veyron Grand Sport Vitesse and a helicopter, and speaks with a Japanese accent. His robot is modeled after a samurai warrior. He also respects Optimus Prime, calling him "sensei", but disregards Bumblebee's skills as a warrior which causes a rivalry between them, though in battle they work very well together. Drift is partnered with Dinobot Slug where he rides into battle at the film's climax.

In the concept art, his both vehicle and robot were colored black and orange 2013 Bugatti Veyron Grand Sport Vitesse and he was known as "Samurai", before changing back to black and blue.

Crosshairs

John DiMaggio voices Crosshairs, an Autobot paratrooper who transforms into a green 2014 C7 Corvette Stingray and speaks with an English accent. His robot mode is modeled after a human paratrooper with goggles and sidearm machine guns. He was originally called Slingshot, but later the name was changed to Crosshairs. He also rides with Dinobot Scorn into battle at the film's climax, who later named him "Spike".

He also appeared in the 2007 comics and toyline and the Dark of the Moon toyline, and also a repaint of Hot Shot who appeared in the Age of Extinction toyline.

Dinobots

The Dinobots, known as the "Legendary Warriors", have been confirmed by Lorenzo di Bonaventura in Age of Extinction. They appeared to be the big size robots with spikes all over and resemble the Knight armors. In the film, they were captured inside of their ship, which Lockdown takes over as his prison ship, long ago, later until Optimus freed and tame them for their aid and their freedom; first they killed the KSI drones, later protect the Seed, until Lockdown returns and uses the magnet to recapture them, but Optimus destroy it. At the end of the film, they were set free by Optimus Prime. Unlike the Dinobots in the other series, none of them spoke in the film, but growl.

Grimlock

Grimlock is the leader of the Dinobots who transforms into a mechanical horned fire-breathing Tyrannosaurus. He is colored black and orange in the toy line. Like Grimlock's other versions, he is at odds with Optimus, until he beats Grimlock in a duel, allowing Optimus to ride him into battle in Hong Kong. Grimlock is partnered with Optimus Prime.

In the concept art, he was known as "Black Knight Tyrannosaurus".

Although he is silent in the film, Gregg Berger voiced him in the Rise of the Dark Spark. Also, his eyes for both robot and dino are red eyes in the movie and blue in the toy line.

Scorn

Scorn is the Dinobots' demolition specialist who transforms into a mechanical three-sailed Spinosaurus. He is colored orange and red in the toy line, with one sail (two sails in Construct Bots). Scorn has a right arm and a left tail arm (two arms in Construct Bots) and partnered with Crosshairs, who named him "Spike".

In the concept art, he was known as "Black Knight Spinosaurus".

Slug

Slug is the savage destroyer amongst the Dinobots who transforms into a mechanical spiked and bestial Triceratops. He is colored purple and red in the toy line and partnered with Drift.

In the concept art, he was known as "Black Knight Triceratops". Although his Dino mode has red eyes in the movie and blue in the toy line.

Strafe

Strafe is a Dinobot who specializes in assault infantry and transforms into a mechanical two-headed and two-tailed Pteranodon. He was originally called Swoop (appeared in the toyline), but later the name was changed to Strafe. He is colored black and blue in the toy line and partnered with Bumblebee.

In the concept art, it shows his robot with two heads before changing with one head and he was known as "Black Knight Pteranodon".

Decepticons

In the four films, 43 Decepticons have appeared in the series. By the end of Dark of the Moon, all Decepticons are killed on Earth. But after five years, Megatron is reborn as Galvatron to create new Decepticons.

The Fallen

Tony Todd voices The Fallen, formerly Megatronus, a rogue Prime, the founder of the Decepticons, and Megatron's master.

In 17,000 B.C., he and his brothers set the Harvester on Earth, but when the humans are discovered the other Primes refuse to activate the Harvester, but the Fallen betrays his brothers, stealing the Matrix of Leadership, the only thing that can turn on the Sun Harvester. However, his brothers stopped him and took the Matrix and hid it from him. Years after his betrayal, he is shown aboard the Nemesis in some kind of stasis for an unexplained reason, but the prequel novels for the film say the Fallen was imprisoned in another dimension thousands of years ago by his brethren as a punishment for his betrayal. He is capable of opening Space Bridges at will, and he also has the ability to wield telekinesis, powers restricted to the original Dynasty of Primes. He also wields a metal spear as a melee weapon. During the film, the Fallen seeks to invade Earth with an army of Decepticons and activate the Sun Harvester for an alternative Energon source as well as to get revenge on humanity and the Autobots for his defeat after taking the Matrix of Leadership. Landing on Earth, he uses Earth's telecommunications grid to force the humans to hand over Sam Witwicky, which will lead the Decepticons to the Matrix of Leadership. During the final battle, the Fallen steals the Matrix from a revived Optimus Prime and starts up the Sun Havester, declaring revenge is his at last. However, as the Sun Harvester charges, Jetfire sacrifices himself in order to let Optimus take his parts. After Rachet and Jolt fuse Optimus with Jetfire's corpse, making him more powerful, Optimus Prime destroys the Sun Harvester and fights the Fallen. Megatron tries to help his master, but is quickly defeated. After a short, but fierce battle, the Fallen is finally destroyed by Optimus Prime.

Although he does not transform in the film, his toy versions transform into a "Cybertronian destroyer" aircraft. The writers selected The Fallen after looking through various cartoons and comics for new characters, because he was the most "elemental" villain. At some point, Leonard Nimoy and Frank Welker (the original voice of Megatron) were considered for voicing the Fallen, before Todd came in (who had previously worked with director Michael Bay on The Rock).

Megatron/Galvatron

Hugo Weaving voices Megatron, the ruthless leader of the Decepticons, Optimus Prime's archenemy and a disciple of the Fallen in the first three films.

Thousands of years ago, Megatron had crash-landed on Earth in the Arctic in his quest to obtain the AllSpark. When he is defrosted, he keeps his original alien jet form out of vanity. Frank Welker, who played the part on television opposite Peter Cullen, auditioned to reprise the role. Bay considered his voice too soft and felt it would be disrespectful to ask Welker to change it. Weaving's voice had been the inspiration Bay gave to his animators for the character, and the character's voice had become that of Weaving in the director's mind. Weaving recorded his lines in Australia, directed by Bay through iChat. The deviation from Megatron's 1980s Walther P38 pistol form was done to avoid morphing. Orci and Kurtzman also felt it would be "the equivalent to Darth Vader [becoming] his own lightsaber and having someone else swing him around". Fans disliked leaked images of the character's head design, so it was redesigned during filming. The prototype design had a much narrower face than the one seen in the finished film. Optimus calls Megatron his brother; Cullen interpreted this line literally, but while the writers state this was the case in early drafts, they consider the line in its final context to be metaphorical. During the final battle in Mission City, Megatron kills Jazz, the Autobot top lieutenant, and duels with Optimus Prime, quickly gaining the upper hand. After being weakened by human fighter jets, Megatron is killed by Sam, who pushes the AllSpark into his spark core, avenging Jazz's death. Later, Megatron's body is dumped into the deepest part of the Laurentian Abyss.

In Revenge of the Fallen, Megatron returns. He is revealed to be the lieutenant and apprentice of the Fallen, who is the founder and true leader of the Decepticons. Despite Michael Bay's initial claims of him not returning after he was killed and thrown into the Laurentian Abyss in the first film, Megatron is resurrected by the Constructicons with a shard of the AllSpark. Upon being revived, Megatron gains a new alternative mode as a Cybertronian flying tank, sometimes mistaken for the Cybertronian Jet he turned into in the first film. Though he remains extremely powerful, Megatron isn't as strong as he was in the first film, due to his damaged parts being replaced by the parts of a weak Decepticon. He kills Optimus Prime and later pursues Sam Witwicky for vengeance and to obtain the AllSpark knowledge the human possess within his mind. In Eygpt, Megatron fights a resurrected and upgraded Optimus, but is overpowered and badly damaged, losing the right side of his face and his right arm in the process. Megatron then watches as the Fallen is destroyed. Afterwards, Megatron retreats with Starscream, swearing revenge. When reviving the character, the writers chose not to rename him Galvatron so as to not confuse the general audience.

In Dark of the Moon, Megatron's final appearance. Despite his right arm and his half face repaired at the end of last film, Megatron changes his vehicle mode to an armored rusty Mack Titan 10-wheeler fuel tank truck equipped with heavy weaponry. After Optimus Prime destroyed half of his face in Revenge of the Fallen, Megatron sometimes hides it by using a cowl. Instead of using a Fusion Cannon integrated into his arm, he uses a handheld version of it, which is sometimes referred to as a "Fusion shotgun." It is revealed that Megatron made a secret deal with former Autobot leader Sentinel Prime, to invade Earth with an army using Space Bridge pillars and use humanity to rebuild their damaged planet together. However, Megatron is betrayed by Sentinel and has command of the Decepticons taken from him. During the battle in Chicago, Sam's girlfriend Carly goads him back into action; Megatron ambushes and cripples Sentinel. When Cybertron's trip through the Space Bridge fails, Megatron attempts to make a false truce with Optimus, mockingly saying "Who would you be without me, Prime?" Optimus refuses, however, knowing that Megatron would not give in so easily, and attacks his eternal foe, tearing off Megatron's head with a battle axe, finally killing him and avenging Jazz's death again.

In a secret concept art of Dark of the Moon, Megatron was known as Cyclonus for his new vehicle design.

Frank Welker voices Galvatron, a Decepticon inspired by Optimus Prime who finally makes his debut in Age of Extinction,serving as the secondary antagonist.Five years after the Chicago war, Megatron's head is seen at KSI, where a captive Brains discovers that his mind is still alive and in a deep stasis. Megatron's mind manipulates Joshua Joyce and his creation of the artificial Transformers, including a Galvatron model. Finally, Megatron takes over Galvatron's body (accepting the name as his new identity) and is able to take control of other artificial Transformers as well. a human-made KSI Transformer inspired by Optimus Prime who is later possessed by Megatron's mind and adopts the identity for himself. In the film, the KSI build the "Galvatron" prototype. Later, Megatron takes over Galvatron's body (accepting the name as his new identity) and is able to take control of other artificial Transformers as well and learns of Harold Attinger's deal with Lockdown for the human to obtain a Seed, a cyber-forming bomb. He plots to wait until Attinger will get the Seed, planning to use it to destroy a human city and rebuild the Decepticon army. Galvatron is first deployed to catch Optimus Prime. The two fight, but Galvatron withdraws on Joshua's orders after Lockdown unexpectedly arrives. During the battle however, Galvatron shows several signs of independence; he destroys several civilian cars, fires missiles unbidden and even talks, something that he was never programmed to do. Galvatron later takes control of the KSI drones and uses them as his minions to retrieve the Seed. But his army is soon destroyed along with Lockdown and Attinger. However, Galvatron survives and flees, vowing that he will meet Optimus again, and declares that he is reborn. Galvatron transforms into a black and grey 2014 Freightliner Argosy cab over truck and he shares the ability of other KSI creations to change his form molecularly instead of just transforming.

In early production, the Freightliner Argosy cab over truck was originally called Motorbreath and Nemesis Prime (who appeared in the toyline, repaint of Evasion Optimus Prime), but the name was later changed as Galvatron.

Starscream

Charlie Adler voices Starscream, Megatron's second-in-command who transforms into a Lockheed Martin F-22 Raptor jet, which is the successor to his original form, the F-15 Eagle. Despite being a popular character, his role is limited because of the film's running time. A post-credits scene of him escaping Earth was added because audiences at test screenings wanted to know what happened to him. This keeps the character's role as the powerful and technologically advanced air commander. Starscream has a rather negative relationship with Megatron.

He flew into space at the end of the 2007 film, and returns in Revenge of the Fallen bearing Cybertronian tattoos and symbols on his body and commanding a new Decepticon army (actually gained in the pages of an IDW prequel comic book). Orci explained that it was their intention to let Starscream have more dialogue than in the 2007 film and be more connected to the plot, and that dialogue additions made during post-production edged Starscream closer towards his G1 incarnation.

In Dark of the Moon, Starscream is later killed by Sam Witwicky who blows off his head with a small bomb that was designed and given to him by Que, right before his death.

In Age of Extinction, a picture of Starscream appears with a red X indicating his death, and appeared in the toyline.

Barricade

Jess Harnell voices Barricade, a Decepticon scout who transforms into a black Saleen S281 police car, whom Frenzy guides to Sam. Functioning as a scout, Barricade is the perfect Earth infiltrator and inquisitor. He is shown as Bumblebee's rival in the first film.

The character was inspired by the G1 Autobot Prowl, because the writers thought a Decepticon displaying authority would use the police car form. Barricade is able to house Frenzy in a compartment in his chest, ejecting him from his front grill. Takara and Hasbro had designed the flap for his toy and were unaware ILM had taken inspiration from their depiction of the character.

Barricade was soon defeated by Bumblebee, but reappeared when Starscream calls the Decepticons to mobilize. However, he disappeared in the highway, but he does appear in the toy line, video game, and comics for Revenge of the Fallen.

Barricade later reappeared in Dark of the Moon. in the Battle of Chicago. He is seen capturing the Autobots, including Bumblebee, Ratchet, Sideswipe, Dino and Que. He later executing and kill Wheeljack by Soundwave's orders. And soon he is finally killed by a group of NEST soldiers with boomsticks, avenging Wheeljack's death.

In Age of Extinction, footage of Barricade appeared and his death is seen.

Frenzy

Reno Wilson voices Frenzy, a small Decepticon spy and a minion of Barricade who transforms into a silver PGX Boombox and later in his head mode, a black Nokia 8800 without his body. He first attacked Sam and pulled off his jeans, but Mikaela tore Frenzy into two. Later, he got his body back and while attacking a group of humans in the control rooms, Frenzy accidentally kills himself when one of his own shurikens goes full circle and slices his head in two.

In Revenge of the Fallen, Frenzy's head is seen in the basement of Simmons' mother's deli. When Leo approaches the head in a jar, Simmons slaps him with a paper and warns him, "Hey. Still radioactive, hands off."

Blackout

Blackout is a first-strike Decepticon and a first Transformer appeared who transforms into a MH-53J Pave Low III helicopter. He is extremely loyal to Megatron and uses his blaster in his chest, and the blades. He first appeared attacking the base, and most of the humans, expect Lennox and Epps. Later through the film, he calls the Decepticons that Frenzy has located the AllSpark, and his line says "All Hail, Megatron". He later take place in Mission City when he tried to kill Sam and get the cube, soon he is killed by human fighter jets and Lennox, who shoots his spark, when trying to enter a duel between Optimus Prime and Megatron.

Although he is silent in the film, Noah Nelson provides his voice in the game.

He is also has a remodel heads and a repaint for Autobots, both Evac and Whirl.

Scorponok

Scorponok is a Decepticon, a mechanical Scorpion and a minion of Blackout, who is able to dive under sand or other soft landforms and burrow under the surface to attack. In the beginning, he is seen attached on Blackout's back, and deploys him and jumps into the sand. After being damaged by the gunships, Scorponok retreats in the sand, and does not appeared for the rest of the film, while his tail was recovered. Scorponok does not transform in the film, but he transforms in both 2007 film and Revenge of the Fallen toyline.

In Revenge of the Fallen, despite his tail being repaired, Scorponok later reappeared in the final battle in Egypt, where he disembowels and damages Jetfire, but he kills him with a fist.

He and Blackout also appeared in the toyline of Dark of the Moon. He has a robot mode, which didn't appear in the movie.

Brawl

Brawl is a vicious Decepticon demolition specialist who transforms into an dark green M1 Abrams. He has two four-pack missiles on his back, a blade gun on his left arm and a machine gun on his right arm. He even uses his tank cannon (which appeared in the toyline). During Mission City, he loses his left arm by Ratchet and was knocked out by soldiers. However, he gets back up and fights. While firing his arm at soldiers, he is finally killed by Bumblebee, who lost his legs by Starscream, while he is on a GMC tow-truck. For his portrayal, the crew chose to use an Abrams prop built for xXx: State of the Union.

This name was intended to be named Brawl (which appears on all the merchandise), but a subtitled Cybertronian line in the film reads "Devastator reporting". His name was in the production of Barricade's final model of the first film, before changing back to Barricade.

Although he is silent in the film, David Sobolov provides his voice in the video game.

He also appeared has a Deep Desert repaint which appeared in both 2007 (leader class with blue eyes) and Revenge of the Fallen toyline (with red eyes), and even a light blue repaint of Tankor, who also appeared in the second film's toyline. His deep desert model appeared in Dark of the Moon in Chicago and seen fighting Autobots before being killed by Optimus.

Bonecrusher

Jim Wood voices Bonecrusher, a very hate fueled and cantankerous Decepticon who transforms into a Buffalo H Mine-Protected vehicle. The animators modeled his fighting styles on hockey and football players. His alternate form had been chosen based on a promotional image in which the fork looked much bigger than it really was, so for the movie, the vehicle was modified to fit a larger fork. He first appeared when Starscream calls the Decepticons for the location of the AllSpark. He later attacks Optimus on the highway to Mission City, but soon beheaded and killed by Optimus Prime. Despite his death, it is stated in the toy bio for his Jungle variation that he survived the events of the first film.

He is voiced by Daniel Riordan in the Transformers: The Game.

In Revenge of the Fallen, Bonecrusher is reused in the battle of Egypt, alongside the Protoforms and was seen attacking Ironhide, Arcee, Chromia, and Elita-One.

Soundwave

Frank Welker voices Soundwave, the Decepticon Communication Officer. He doesn't adopt any robot or vehicle modes and is only seen in what the toyline calls "satellite mode", which he uses to attach himself to a military satellite to coordinate the Decepticons' movements around the world. His toy version, however, apart from this mode, has a proper robot mode and transforms into a Cybertronian craft. The concept artists also designed an Earth form of a Chevrolet Silverado for him to upgrade into, which was ultimately dropped.

The filmmakers had tried to work Soundwave into the 2007 film twice, and these roles eventually evolved into Blackout and Frenzy. The latter character was particularly thought to be too different from the original.

In Dark of the Moon, Soundwave now transforms into a silver Mercedes-Benz SLS AMG who poses as a car given to Carly by Dylan. He is later killed by Bumblebee in the battle of Chicago.

In early production of Dark of the Moon, Soundwave was known as Breakdown for his vehicle design.

In Age of Extinction, Soundwave appeared in the toyline, and repainted as "Darkside Soundwave".

Ravage

Frank Welker voices Ravage, a Decepticon infiltration expert and a minion of Soundwave that resembles a large one-eyed Jaguar and is a fierce hunting machine. He is later killed by Bumblebee in Revenge of the Fallen.

Early in production, he was meant to adopt a fish/submarine-like form right after he first falls into the ocean, and while this was ultimately left out of the movie, it can still be seen in the film's toyline. In the NEST Global Alliance toyline, a Recon Ravage is executive toy to win three stickers.

Laserbeak

Keith Szarabajka voices Laserbeak, a Decepticon infiltration expert and a minion of Soundwave that resembles a mechanical condor-like. Like his predecessor, Ravage, Laserbeak serves as a scout and spy for the Decepticons, and transforms into a Gyrodyne and a variety of electronic devices, such as a desktop computer, and an audio system and even a child size pink version of Bumblebee. He is later killed on a Decepticon ship (piloted by Bumblebee) when Sam holds his head in front of a gun barrel which Bumblebee fires, blowing off Laserbeak's head for interfering with Sam's confrontation with Dylan. Unlike other robots in the film series, he has multiple alternate modes. Unique to this incarnation, he is intelligent and able to speak English.

In early production, Laserbeak was known as "Buzzard".

Szarabajka previously voiced Ironhide in the War for Cybertron. Although Laserbeak does not speak in any comics, shows, or games in Transformers.

Constructicons

The Constructicons are a Decepticon sub-faction of Decepticons who transform into construction vehicles in Revenge of the Fallen and Dark of the Moon.

Devastator

Frank Welker voices Devastator, a 46 feet (14 m) tall (hunched over) massive robot formed by several combining construction vehicles, who walks in a four-legged fashion resembling a gorilla. He is physically unable to stand up straight. If he did, would be 100 feet (30 m) to 120 feet (37 m). His jaws can open up to form some sort of suction vortex, and he has grappling hooks he is seen using to climb a pyramid. A Combiner, Devastator is the Decepticons' ultimate weapon. He is killed by a railgun. Although Devastator's face was only gray in the toyline, but in the film his face is red, and has two chain balls on his bottom.

Although Devastator was originally conceived to be made up of the other Constructicons (which is also reflected in the toyline) in the film he was made to be independent from them. As a result of this change, Overload and Hightower were dropped as robots, only their once-intended vehicle modes being seen in the movie. Both Overload and Hightower's robot modes can still be seen in toy form in Takara Tomy's EZ Collection DX Devastator.

The following vehicles make up Devastator's various body parts consist of:

• Scavenger - Upper torso
• Scrapper - Right arm
• Hightower - Left arm
• Mixmaster - Head
• Rampage - Left leg
• Long Haul - Right leg
• Overload - Lower torso
• Second Bulldozer - Shovel/left hand
• Yellow Dump Truck - Dump truck/left leg

Devastator also appeared in the toyline of Age of Extinction.

Demolishor

Calvin Wimmer voices Demolishor, a large Constructicon who transforms into a white and red Terex O&K RH 400 hydraulic mining excavator. In robot mode, his treads turn into huge wheels, enabling him to roll either on the two of them, or only on the front one, with the rear lifted behind his head. He is killed when Optimus Prime shoots him the right eye at point blank range. In the film's credits, he was known as "Wheelbot".

He is voiced by Fred Tatasciore in the video game.

Rampage

Kevin Michael Richardson voices Rampage, a Constructicon who transforms into a red Caterpillar D9T bulldozer with model number M930. His robot mode resembles an upright-standing snake with his treads coming out of his hands, which he uses as whips. In the toyline, this mode is called "jackhammer mode", with his actual robot mode resembling a centaur with four spider-like legs. He is then killed by Bumblebee. In the film's credits, he was known as "Skipjack", when a Cybertronian line reads "Rampage, spring the trap" by Starscream, but he is red in the film and yellow in the toy line.

Mixmaster

Mixmaster is a Constructicon who transforms into a black and silver Mack concrete mixer truck. He is briefly seen to have a third "battle mode" which appears to be a gun emplacement.

According to his toy bio, he is an expert in chemistry and explosives who makes explosives and poisons for the other Decepticons' weapons. Some of the concept art shows him as a McNeilus mixer truck. He is killed by Jetfire.

Although he is silent in the film, Dave Boat provides his voice in the Dark of the Moon video game, then got killed again by Ironhide.

Mixmaster also appears in Transformers: The Game.

Long Haul

Long Haul is a Constructicon who transforms into a green Caterpillar 773B dump truck. Long Haul's robot mode was designed by freelance artist Josh Nizzi as fan art of the original character, by the time Revenge of the Fallen had just been greenlit. The fan art impressed Bay enough to hire him on to the film. He is killed in an airstrike during the final battle in Egypt.

Although in the movie Long Haul's alt mode is a Caterpiller 773B, a relatively small truck, Nizzi had originally meant Long Haul to be a Caterpillar 797, one of the largest dump trucks in the world.

Although he is silent in the film, Neil Kaplan provides his voice in the video games.

Originally, a yellow clone of Long Haul called Payload was meant to take part in the formation of Devastator, but this was dropped as Devastator was ultimately made to be formed by other vehicles that come together.

For Dark of the Moon, Long Haul's model is reused for a Decepticon present in Chicago and seen fighting Autobots before being killed by Optimus.

Scrapper

Scrapper is a Constructicon who transforms into a yellow Caterpillar 992G scoop loader. He is seen to be able to use his left arm as a chain mace. He is killed in an airstrike during the final battle in Egypt.

For Dark of the Moon, Scrapper's model is reused for a Decepticon present in Chicago and seen fighting Autobots before being killed by Optimus.

Scrapper also appears in Transformers: The Game.

Scavenger

Scavenger is a large Constructicon who shares the same model of Demolishor and his robot mode appeared in the toyline. He appeared in the final battle of Egypt, where he and the Constructicons form Devastator, but soon killed by a Railgun, alongside the Constructicons.

Overload

Overload is a Constructicon who transformed into a red KW Dart D4661 Tractor Truck articulated dump truck. Overload's robot mode, which appears to be a multi-armed, multi-legged destruction causing robot, can still be seen in toy form in Takara Tomy's EZ Collection DX Devastator.

Hightower

Hightower is a Constructicon who transformed into a yellow KOBELCO CKE2500 II crawler crane. He is only seen in vehicle mode. Hightower's robot mode, which appears to model a robot with treads for feet and a wrecking ball as a key weapon, can still be seen in toy form in Takara Tomy's EZ Collection DX Devastator, while his G1 repaint counterpart, Hook, also appeared.

Scrapmetal

Scrapmetal is a Constructicon who transforms into a yellow Volvo EC700C crawler excavator fitted with a Stanley UP 45SV attachment. He joins Mixmaster, Long Haul and Rampage on the retrieval mission to recover Megatron. Then during Megatron's retrieval, he is referred to as "Ze Little One" by The Doctor, and then ripped apart by the others in order to provide spare parts for Megatron. He looks the same model as Scrapper.

Sideways

Sideways is a Decepticon surveillance agent who transforms into a silver Audi R8 hiding with Demolishor in Shanghai, China until he is discovered by the Autobots. After getting chased by Arcee and the twins, NEST brought in Sideswipe, who sped in and then sliced Sideways in half, killing him. Sideways prefers to lurk behind larger Decepticons to stay out of danger.

Although he is silent in the film, John DiMaggio provides his voice in the Revenge of the Fallen.

For Dark of the Moon, Sideways is reused for a Decepticon present in Chicago and seen fighting Autobots before being killed by Optimus.

In Transformers: The Ride, Sideways is killed by Bumblebee.

Reedman

Frank Welker voices Reedman, a one-eyed razor-thin robot. Reedman appears when at a certain point in the film, Ravage is seen deploying a load of marble-sized "microcons" that adopt an intermediate bug-like robot form, and end up grouping together to form Reedman. Reedman's extremely thin frame serves him as his main ability, by making him virtually invisible as long as he is facing directly at his enemy. His fate isn't shown in the film, the novelization and comic depict him being destroyed by Carter Newell.

The Doctor

John Di Crosta voices The Doctor, a small spider-like medic and scientist equipped with tools who transforms into a microscope. He first appeared deployed from Ravage and order Mixmaster, Rampage and Long Haul to Kill ze little one (Scrapmetal) to spare his parts for Megatron, and later uses the stolen shard (while Mikaela has the other one) to revive the leader back to life. He is seen again, using to extract information, using his assistants, two flying bots and a worm, examining Sam's brain. The packaging of his Scout-Class figure, his name Scalpel, details he is skilled in dissecting and rebuilding almost any living organism. His fate isn't shown in the film, the novelization and comic depict him being destroyed by Optimus Prime upon his arrival.

In Dark of The Moon, The Doctor is reused for a group of his copies to repair Megatron's damage head after his last battle with Optimus in the previous film's climax. They are seen in Africa and later in the Battle of Chicago, as Megatron kills several of them.

Alice

Isabel Lucas plays Alice, a Decepticon Pretender who is sent from the Decepticons to get the information that Sam has when he came in contact with the fragment of the AllSpark, but she is later killed by Mikaela Banes. Though not covered in the film, the novelization and comic adaptation explains her adopted earth mode as her duplicating the appearance of a theme park animatronic figure of Alice in Wonderland.

Grindor

Frank Welker voices Grindor, a Decepticon close combat specialist and master strategist who transforms into a CH-53E Super Stallion helicopter, and shared the same body as Blackout's. Grindor, Starscream and Megatron fight against Optimus Prime in order to capture Sam Witwicky. He is killed when Optimus rips his head apart with a pair of energon hooks.

Insecticon

An Insecticon is a small insect-like Decepticon who is a mechanical beetles. Although it does not transform in the film, but only their robot modes in the Hunt for the Decepticons toyline.

In Revenge of the Fallen, during the final battle of Egypt, an Insecticon was first seen searching for Sam alongside Starscream, Long Haul, Ravage, and several Protoforms. It is able to find Sam, but deactivated and killed by Sam when he gives the other Decepticons his location.

In Age of Extinction, the Insecticon is reused for a group of its copies. They made a cameo, when Brains is captured by KSI to infect him to switch Megatron's mind, within his head, to KSI's Galvatron drone. Although they were not named in the film, as Brains calls them "Chromosomes".

Shockwave

Frank Welker voices Shockwave, a ruthless, extremely logical, cruel and emotionless Decepticon scientist. He is eventually killed by Optimus Prime, who rips his throat out. Although Shockwave does not transform in the film, he transforms into a Cybertronian self-propelled artillery vehicle in the Dark of the Moon toyline.

Like his original G1 appearance, Shockwave's head features a single red eye, and has a gun in place of one of his hands, with a tube connecting it to his back. Visual effects supervisor Scott Farrar said that the lack of eyes and mouth in Shockwave's design means "you have to read Shockwave through just the emotions of his face, almost like a silent-era film star," which caused the eye to have an intrinsic design, with a lens, a moving iris and an oscillating light.

Corey Burton, who voiced Shockwave in The Transformers and Transformers Animated, was offered the role, but he declined it stating he does not want to be in a big budget movie, so actor David Warner was considered to voice him before the role was given to Welker.

In early production, Shockwave was known as "Blitzwing".

Shockwave also appears in Transformers: The Game, as a helicopter.

In Age of Extinction, a picture of Shockwave appears with a red X indicating his death.

Driller

The Driller is Shockwave's pet; a giant, tentacled Mongolian death worm-like Cybertronian creature, who is used for drilling purposes. Later in the Battle of Chicago, Shockwave commands his pet to tear down a large building, but the beast is decapitated and killed by Optimus Prime, in jet mode. An enraged Shockwave tried to avenge his pet's death by shooting Optimus.

In early production, the Driller was known as "Colossus".

Igor

Greg Berg voices Igor, a deformed Decepticon that scurries about Megatron at his base in Africa, he is actually the modified severed head of Long Haul, who was killed in the previous film. He is last seen eating the head of the Abraham Lincoln statue in Lincoln Memorial.

In early production, Igor was known as "Undermine".

Dreads

The Dreads are a group of Decepticons who follow the Autobots back from the moon and transform into black Chevrolet Suburban emergency vehicles. They also seem to vaguely resemble the Predator. They attacked Sam, Bumblebee, Sideswipe, and Dino on the highway and later fought Ironhide and Sideswipe by throwing their explosive darts at the Autobots.

Crankcase

Crankcase is the leader of the Dreads, and he specializes in stealing information. Crankcase was killed by the Autobot Ironhide with the help of Sideswipe.

In early production, Crankcase was known as "Dreadwind".

Crowbar

Jim Wood voices Crowbar, the Dreads' second-in-command who specializes in getting into secured areas and systems. He and Crankase fought Sideswipe and Ironhide holding both his guns at them. He is killed by a head shot from Ironhide. In the toyline, Crowbar is depicted as a black Carbon Motors E7 police car.

During the highway battle, Bonecrusher's growl from the first movie is reused for Crowbar.

In early production, Crowbar was known as "Hooligan".

Hatchet

Hatchet is a master strategist for the Decepticons, who has an animal-like robot mode. He is killed by Bumblebee and Dino/Mirage on the highway. In the toyline, Hatchet is depicted as a black Eurofighter Typhoon.

Devcon is a quadruped Decepticon present in Chicago of Dark of the Moon. Concept art show that his alternate mode is that of a Russian MAZ-7310 missile launcher. He is killed by the combined firepower of the Wreckers and NEST soldiers.

Devcon's robot mode resembles the monster from Cloverfield, in which he bares double-jointed forelegs and short back legs, as well as a pair of underslung appendages.

KSI Drones/New Decepticons

The KSI Drones are the human-made Transformers who were build by KSI. They have the ability to change their forms molecularly instead of just transforming. They were build with the metal extracted from the remains of the dead Transformers from the Battle of Chicago (including Sentinel Prime, Megatron, Starscream, Soundwave, Shockwave, Driller, Barricade, Laserbeak, Decepticon Protoforms, Ratchet, Que and Leadfoot, possibly Sideswipe, Dino, Roadbuster and Topspin). They also resemble past Transformers, both Autobots and Decepticons. They were originally mindless drones remote-controlled by humans, but later were granted autonomy by Megatron (now known as Galvatron) in his new body, organizing them into a new Decepticon army. They fought in the battle of Hong Kong to get the Seed (to use it to turn everything metal and build a new army), but soon destroyed by the Autobots and Dinobots.

Also, a KSI Decepticon that advertising Oreo's is seen getting its arm blown off by Optimus Prime. A fourth Dread made a cameo, alongside Galvatron and Stinger, but was never seen again. An orange McLaren MP4-12C and a white Aston Martin DBS V12 are seen driving with Galvatron, Stinger and Junkheap, but they never appear in their robot modes.

Stinger

Stinger is a Decepticon spy and sabotage specialist inspired by Bumblebee who transforms into a red and black 2013 Pagani Huayra. He appears to be the same red model of Bumblebee, when he thinks that he's better than him, before kicking his back, knocking him down. His head bears the resemblance to Waspinator from Animated. He is later killed by Bumblebee and his head is eaten by Strafe.

In early production, Stinger was known as "Widow Maker", a female robot.

Junkheap is a Decepticon who transforms into a green Isuzu Giga garbage truck of Waste Management, Inc. He has the ability to split into three different component bots that share the same single consciousness at will and were seen killed by Hound in a fight, and Optimus Prime with Lockdown's grenade. Although he transforms into a garbage truck, he retained his three-man splitting technique Reflector from the original 80's Cartoon.

In Dark of the Moon, a Decepticon transforms into the same garbage truck in the American style with the same body type of Long Haul's.

Traxes

The Traxes are the mass-produced Decepticon foot soldiers inspired by Roadbuster who transform into multiple different colored (red, blue, black, silver, and white) Chevrolet Traxes. They appear to have green, red, purplish blue, orange or yellow visors in their faces and blades in their arms. They were originally called Vehicons (appeared in Kre-O sets), but later these names were changed to Traxes and resembles them from Prime. Most of them are killed by the Autobots and Dinobots, and the rest killed by Optimus Prime with Lockdown's grenade.

Two Heads

The Two Heads are the two-headed Decepticons inspired by and made from the remains of, Shockwave, who has a left head with a horn and a right head with two horns, and colored purple.

After Lockdown was killed, another led to get Optimus and the humans, before being killed by Lockdown's grenade.

KSI Bosses

The KSI Bosses are the mass-produced Decepticon captains inspired by Barricade who appeared to have turbines for flight. Most of them are killed by the Autobots and Dinobots, and the rest killed by Optimus Prime with Lockdown's grenade.

Their designs are based on the unused concept art form Revenge of the Fallen for Cyclonus and their electro whips and blades on their arms did not appear in the film, but only their guns do.

Other Decepticons

• Decepticon Protoforms - A large Decepticon army who appeared in each films' final battles. In Dark of the Moon, they have been seen riding Cybertronian starfighters that can transform into Cybertronian hovercrafts and several large ships. Also, their heads resembles Blackout and Crankcase. Most of them were killed in Revenge of the Fallen during the battle of Egypt, and rest killed in Dark of the Moon during the battle of Chicago. They also appeared in the video footage of the battle of Chicago in Age of Extinction, while their large ships were recovered after the Battle of Chicago, Cybertronian starfighters are reused for Lockdown's ship and upgraded, and soon replaced with Traxes.
• A Police car
• Two Fire trucks
• A pickup Decepticon who transforms into a Chevrolet Silverado 1500

Samuel James "Sam" Witwicky is portrayed by Shia LaBeouf in the first three films in the Transformers film series. In early versions of the script, Sam had the nickname "Spike" (the name of the main character in the original Transformers series). This idea was later scrapped because, according to writer Roberto Orci, these nicknames were appropriate for a mechanic and an oil rig worker in the animated series, occupations in which the characters did not work in the film. According to Roberto Orci, the character of Sam was written as a "2007 version of Marty McFly". Sam Witwicky did not return for the fourth film; his character is later replaced by Cade Yeager (portrayed by Mark Wahlberg).

Movie plot

In Transformers, Sam Witwicky was a social outcast who unintentionally buys Bumblebee as his first car. Sam is at first unaware of his car being a Transformer, despite the fact that Bumblebee was responsible for helping Sam to (somewhat) get close to his crush, Mikaela Banes. During the first night, Bumblebee leaves the house, which caused Sam to follow believing his car had been stolen. Later that night, he becomes surprised to find that his car became a robot. After being saved from Barricade by Bumblebee, Sam learns the full story as he helps the Autobots by keeping the AllSpark away from the Decepticons until he uses it to kill Megatron.

In Transformers: Revenge of the Fallen, Sam is going to college and is trying to have a normal life and get away from the world savior status. But while getting ready, Sam finds a sliver of the AllSpark on his jacket which gives him visions, causing him to suffer a mental breakdown as a result. Optimus turns to him for help in convincing the human government to allow the Autobots to stay. Sam refuses, saying he wants a normal life and Optimus doesn't need him anymore to which Optimus replies that they need Sam more than he knows. One of the girls in Sam's dorm who apparently likes him, Alice, turns out to be a Decepticon Pretender who attacks him by lying down on him. Sam is saved by Mikaela, who kills Alice. Sam is then later abducted by Decepticons to acquire the information in Sam's mind before Megatron can vent out his aggression on the boy. Megatron makes Sam lie down on a table before having Scalpel remove his brain. But after being saved by Optimus, who is killed during the fight, Sam ends up leading Mikaela, Bumblebee, his roommate Leo, the Twins: Skids and Mudflap, and Simmons in a quest to find the Matrix and use it to revive Optimus. During the final battle, Sam is killed by Megatron until he was revived by the Dynasty of Primes so he can resurrect Optimus, allowing him (Optimus) to kill the Fallen and save Earth. With Earth saved once more, Sam finally admits he loves Mikaela. On an aircraft carrier later, he and Optimus thank each other, Optimus thanking Sam for saving his life and Sam for Optimus believing in him.

In Transformers: Dark of the Moon, his final appearance, Sam has been dumped by Mikaela and has a new girlfriend named Carly Spencer whom he met after being given a Presidential Medal of Freedom by the President Barack Obama for his heroic accomplishments in the past. Sam now lives with Carly Spencer, a pet dog and former Decepticon Wheelie, and his partner, Brains. Bumblebee no longer lives with him, working with the other Autobots on secret missions, forcing Sam to drive a rundown car that vaguely resembles a small Bumblebee, Sam ends up finding a job as a mail boy despite wanting to work with the Autobots, but is dragged back into the war by Decepticon collaborator Jerry Wang and Laserbeak. Sam, with the help of Simmons, figures out the Decepticons' plot and is forced by Dylan Gould into finding out the Autobots' plans for the Decepticons. Sam is devastated when the Autobots are exiled from the planet and then apparently destroyed and teams up with Epps and other former NEST soldiers to rescue Carly from Chicago. He later sees the Autobots returned after faking their death. Sam succeeds with help from Bumblebee and in the battle that follows, he kills Starscream and Dylan Gould who retriggers the space bridge after Optimus stops it. Sam reunites with Carly after the Decepticons are defeated and admits he loves her.

A mini-diorama gift set with Barricade and figurines of Sam and Mikaela, along with an extra, non-poseable Frenzy figure.

The original "radiator" Frenzy available with Screen Battles: First Encounter Barricade was remolded in black (matching the car) but was installed with additional piece of plastic, preventing the black Frenzy figure from being removed -- due to redundancy -- without unscrewing the base of the Barricade's hood. This version of Frenzy has been referred to as "Restrictor Plate Frenzy" by collectors.

Mikaela Banes

Mikaela Banes
Transformers character
240px Mikaela Banes in Transformers.
First appearance	Transformers
Last appearance	Transformers: Revenge of the Fallen
Portrayed by	Megan Fox
Information
Species	Human
Gender	Female
Occupation	Student Ally to the Autobots Mechanic
Family	Cal Banes (father)
Significant other(s)	Sam Witwicky
Nationality	American

In the first two Transformers films, Mikaela Banes (portrayed by Megan Fox) is Sam Witwicky's first love interest. Differentiated from "typical" women in her age group, she has inherited mechanical skills from her father, Cal, a grease monkey and paroled car thief.

IDW Publishing

Mikaela was present shortly after the battle at Mission City in Transformers: Alliance #1 (December 2008) by IDW Publishing.

Films

In Transformers, Mikaela is initially the girlfriend of football player Trent DeMarco; however, she soon ditches him because of his snobbish attitude and because he treats her like a trophy wife. Sam offers her a ride home, as he has a crush on her, and Mikaela accepts Sam's offer. She inspects Sam's broken-down 1976 Chevrolet Camaro (nicknamed Bumblebee) in an empty lovers lane and is astonished at the various modifications present in the engine bay. Unfortunately, the visuals of the actual engine under the hood show a continuity error on the part of the filmmakers: the shot shows that Bumblebee has a Kinsler crossram fuel injection intake manifold, as her character discusses a double-pumper carburetor. She also surprises Sam with her knowledge about cars which he finds more attractive than the popular shallow girl she acts like around others. When asked why she keeps her mechanical expertise a secret, she says, "guys don't like it when you know more about cars than they do." Mikaela criticizes the poor conditions of Bumblebee's vehicle mode, causing him to scan a passing 2007 Camaro Concept and transform into the same model. She fights in the Battle of Mission City, initially pulling the seriously injured Bumblebee out of battle, but is ultimately unable to leave them to fight alone. She tells Bumblebee that if he's willing to fight, she'll take him back in and navigate. He acquiesces and with her help, Bumblebee rejoins the battle and destroys Brawl. After the battle, she and Sam begin dating because when they meet the Autobots, Ratchet said that he knows Sam has a crush on Mikaela and tells everyone.

Mikaela returns in the 2009 sequel Transformers: Revenge of the Fallen, carrying on a long-distance relationship with Sam. As he goes off to college, Sam entrusts her with a fragment of the AllSpark, which he found in the jacket he was wearing when he killed Megatron. Mikaela hides the fragment in a safe at her father's motorcycle repair shop, but she is followed by the Decepticon spy Wheelie, who is intent on recovering the fragment. She catches the spy and interrogates him. After going to inform Sam, Mikaela saves him from the Decepticon Pretender Alice (whom she kills and also found kissing Sam), only to be captured by Grindor and taken to the recently repaired Megatron. Rescued by Optimus Prime, Mikaela and everyone escape, and on the recommendation of Sam's roommate Leo, they seek help from a man who runs a robot conspiracy website. He is later revealed to be Agent Simmons. Simmons and Wheelie lead them to Jetfire, who uses a Space Bridge to transport the group to Egypt, where the Autobots and their allies battle the Decepticons and The Fallen. She is devastated when Sam apparently dies, but is ecstatic when he is revived and finally tells her he loves her. She survives the battle and returns home. Seen in the credits Sam kisses Mikaela goodbye as he returns to college.

Mikaela does not appear in the 2011 sequel Transformers: Dark of the Moon due to Megan Fox being fired.

IDW Publishing

In "Rising Storm", Carly was working a career fair in Philadelphia when the Decepticons targeted Sam Witwicky and his Autobot friend Bumblebee for harboring their escaped "pet", Brains. As the place became a battlefield, Carly quickly proved capable of defending herself. Seeing that Sam was about to be killed by Space Case, Carly used a weapon attached to one of the fallen Transformers around her to fend off the Decepticon. After saving Sam, they realized that they had met before, albeit under less deadly conditions. Soon, the pair were saved from subsequent danger by the arrival of the rest of the Autobots. When Brains is welcomed into the Autobot ranks, Sam traded barbs with her to see how well she was taking this whole experience.

Books

Movie plot

Carly Spencer as she appears in Transformers: Dark of the Moon.

The two met after Mikaela dumped Sam and he got a Medal of Freedom for his heroism. Carly believes Sam's stories and is annoyed by Brains and Wheelie who live with them. Carly works for Dylan Gould as a curator and is given an expensive car, a Mercedes-Benz SLS AMG, by him, making Sam jealous. Carly gets annoyed when Sam decides to work with Simmons on figuring out what the Decepticons are doing rather than going to Dylan's party with her and leaves angrily. She is shocked when it turns out that Dylan is a Decepticon collaborator and is taken hostage by him, Soundwave, who reveals himself to be the SLS in disguise, and Laserbeak to force Sam to cooperate. Sam launches a rescue mission for her and with the help of Bumblebee, rescues her and kills Laserbeak before using a shot-down drone to relay what she knew of the Decepticons' plans to NEST. During the battle, Carly travels with Sam and Epps' team to stop the plan and is attacked by Starscream who Sam kills. While Sam heads off to stop the space bridge, Carly convinces Megatron to help Optimus against Sentinel Prime, leading to the deaths of Megatron and Sentinel. Carly reunites with Sam after the battle and they admit they love each other.

Reception

In May 2010, it was announced that Huntington-Whiteley would become the new female lead in Transformers: Dark of the Moon, released 29 June 2011, replacing Megan Fox. She had previously worked with the film's director, Michael Bay, on a Victoria's Secret commercial. MTV Networks' NextMovie.com named her one of the 'Breakout Stars to Watch for in 2011'. Prior to the film's release, she won the "Female Star of Tomorrow" award at the 2011 CinemaCon Awards. Critics were highly critical of the acting of Huntington-Whiteley and co-star Shia LaBeouf. Peter Travers stated the two "couldn't be duller." Jason Solomons of The Observer wrote that "we're first introduced to Rosie via a close-up of her bum, segueing straight from the film's opening sequence and titles on to the pert buttocks and underwear of our heroine," and that Huntington-Whiteley's English posh girl accent "renders her practically unintelligible when surrounded by American accents and falling masonry." Much of the criticism towards Rosie Huntington-Whiteley compared her in an unfavorable light to Megan Fox. Lou Lumenick said that her "'acting' makes...Megan Fox look like Meryl Streep in comparison." Baz Bamigboye gave his review of the film the title 'Come back Megan Fox, all is forgiven...'. In a positive review, Drew McWeeny of HitFix said, "She reminds me of Cameron Diaz in The Mask, an actress who doesn't really show off any range, but who gives a natural, winning performance and who is up to the challenge of this particular picture."

NEST

The Non-biological Extraterrestrial Species Treaty, NEST for short, is a team of soldiers led by Lennox and Epps in Revenge of the Fallen and Dark of the Moon. They combined with the Human/Autobot alliance to fight against the Decepticons. They do not appeared in Age of Extinction, but appeared in the video footage of the Battle of Chicago and they were shutdown, replacing them with Cemetery Wind to hunt the Autobots and Decepticons.

General Morshower

Glenn Morshower plays General Morshower, the leader of NEST who communicates with the squad in the Pentagon in Revenge of the Fallen, and Dark of the Moon. He is named after himself.

William Lennox

Josh Duhamel plays William Lennox in the first three films as an eight-man Joint Special Operations Command team in Qatar, who survive Blackout's attack on the base. Lennox has a wife and newborn daughter in the United States. Duhamel was a fan of the toy line as a child, and with Tyrese Gibson, they spent three days in boot camp to prepare for the role.

In the first film, Lennox is United States Army Special Forces Captain. In the second film, he is promoted to Major, and is now part of NEST, an international taskforce battling Decepticons with the Autobots. In the third film, Lennox is again promoted to U.S. Army Lt. Colonel.

Robert Epps

Tyrese Gibson plays United States Air Force Combat Controller Technical Sergeant Robert Epps in the first three films. Duhamel and Gibson were fans of the toy line as children, and Gibson paid the filmmakers so he could be in the film. Gibson spent time learning technical terms and military code from an actual combat controller to make his dialogue sound convincing.

In the second film, Epps is promoted to USAF Master Sergeant, a Combat Controller and a member of NEST. He was given different first names in merchandise, like Ray Epps in The Last Prime storybook, and Julius Epps in The Movie Universe book.

In the third film, Epps left NEST and retired from the U.S. Air Force. He is seen helping the Wreckers with repairs to the Autobot ship Xantium and he also joined the final fight.

Graham

Matthew Marsden plays Graham, an agent of the fictional SASF, and a member of the British Army Special Air Service who joins NEST.

Marsden grew up reading the comics and loved the 2007 film. Bay was impressed with his audition and decided to increase the character's screentime.

Hardcore Eddie

Lester Speight plays Hardcore Eddie, a new NEST member in Dark of the Moon. He is an experienced soldier who has fought in war along with Epps' father many years ago.

Stone

Josh Kelly plays Stone, a former NEST member who went into retirement along with Epps in Dark of the Moon. Kelly also makes an appearance as a Strike Force team member in Revenge of the Fallen.

Mongo

Aaron Garrido plays Mongo, a NEST member in Revenge of the Fallen and Dark of the Moon.

Sector 7

Sector 7 is a secret American government agency, which deals with extraterrestrial technology and threats in Transformers, Revenge of the Fallen and Dark of the Moon.

Seymour Simmons

John Turturro plays Seymour Simmons, an arrogant and paranoid Sector 7 agent and Sam's unlikely ally in the first three films. Sector 7 is a government group of agents created by President Hoover. Bay wanted Steve Buscemi for the role, but he was busy, so Turturro, whom Bay had wanted to work with ever since seeing The Big Lebowski, was cast instead. Turturro gave a slapstick performance, which was intended to be in contrast to the serious military scenes, so that a sense of fun would not completely disappear. A backstory was fashioned for Simmons, explaining his family had served in Sector 7 for generations, giving him a "mother's boy" personality. Bay cut these jokes as they were too crude.

In Revenge of the Fallen, Simmons is now off-duty working in his mother's deli. After he left Sector 7, Simmons took extensive alien documentation with him, which aided Sam in his quest for the Sun Harvester. He is known online by his nickname "Robo-Warrior", and runs a website called www.GiantEffingRobots.com, Leo Spitz's (Sam's roommate) rival site.

In Dark of the Moon, Simmons has written a book, Codename Hero: How Seymour Simmons and the Aliens Saved the World about his adventures with the Autobots. He has lost his leg during the Highway chase by Crowbar and is revealed to have had a relationship with Charlotte Mearing.

Tom Banachek

Michael O'Neill plays Tom Banachek, the head of Sector 7's Advanced Research Division in Transformers.

Maggie Madsen

Rachael Taylor plays Maggie Madsen. She assists the Department of Defense in decoding the virus left by Frenzy. She realizes that those hacking into the government's data files cannot be human, due to the ease with which they made the attack. The writers had initially envisioned Maggie as quirkier and more cyberpunk. The filmmakers opted for Taylor's natural Australian accent to give the film a global sensibility. She found many of her scenes difficult because of the high heels she wore.

Glen Whitmann

Anthony Anderson plays Glen Whitmann, a computer hacker and friend of Maggie..

John Keller

Jon Voight plays the United States Secretary of Defense John Keller, the first one to believe Maggie Madsen's theories. He announces that Sector 7 is dismantled in the end of the film.

Witwicky family

Archibald Witwicky

W. Morgan Sheppard plays Captain Archibald Witwicky, Sam's great-great grandfather. Archibald Witwicky was a Dutch/English sea captain leading an exploration of the Arctic in 1897 when a crew member found something beneath the ice. They started digging and discovered the frozen Megatron. Archibald then accidentally activated Megatron's inertial navigation system which led to a sudden power surge, and died. Unbeknownst to him, the discharge etched a digital map to the AllSpark onto the lenses of his glasses. Blinded and forever marked by his vision, Archibald was committed to a mental institution for life, constantly ranting about visions of the future. A few of his personal items were given to his family, including the pair of glasses. These were passed down over time and eventually given to his great-great-grandson Sam.

In Revenge of the Fallen, Archibald Witwicky is mentioned by Sam Witwicky at college.

Judy Witwicky

Judith "Judy" Witwicky (portrayed by Julie White) is Sam's mother and Ron's wife. She is somewhat flighty as she dresses up Sam's male dog, Mojo, in girly colors and jewelry. She is also very emotional and prone to cursing when in a bad mood. She is one of the few humans to know of the Transformers, though she almost spills the secret in public after eating a brownie laced with marijuana while dropping Sam off at college. While high from the pot brownies, she also babbled to all the nearby girls that her son had lost his virginity, "popped his cherry" (with Mikaela presumably) whilst she was in the house and that he's "quite a catch". Sam and his father Ron quickly hustled her away before she could embarrass them further and reveal the secret of the Autobots. Afterwards, she goes to Paris with Ron where they are kidnapped by the Decepticons to serve as a bargaining chip. She and her husband are later rescued during the final battle in Egypt by Sam and Bumblebee who kills her kidnapper Rampage. Sam insists his parents leave him, but while his father refuses, Judy finally realizes Sam's grown up and convinces Ron to let him go. She appears at the beginning of the third film, upon seeing the Bumblebee no longer lives with Sam, and has bought a similar looking car, which Judy calls a "sad piece of shit". Sam tells her and Ron to leave Washington DC before the Decepticons attack it the next day.

Ron Witwicky

In the Transformers film series, Ronald "Ron" Witwicky (portrayed by Kevin Dunn) is Sam's father and Judy's husband. Unlike the cartoon, from which the film draws much of its inspiration, "Sparkplug" is not used as a nickname, although Roberto Orci has stated that this may occur in any future sequels. In the first film, Ron is oblivious of the true nature of his son's car, even at a point when the entire Autobot team is moving around outside his house. He is portrayed as a caring father but also as a rather picky person, cheapskate and a miser, who is at time obsessive in regards to his lawn and often enjoys playing jokes on his son. He also seems to have an irrational fear of earthquakes. Screenwriter Roberto Orci confirmed Ron knows the truth about the Transformers by the end of the first film. Unlike the first two films, in the third film, he has a beard. He and Judy leave Washington DC before the final battle.

In the Transformers: Dark of the Moon toyline, there is a character named Major Sparkplug who is partnered with the Autobot Whirl.

Jorge Figueroa

Amaury Nolasco plays ACWO Jorge "Fig" Figueroa. Fig is wounded by a rocket fired by Scorponok. In a deleted scene in the Blu-ray version of the film, "Fig" is seen dying after getting wounded by Scorponok, but his character was made to stay alive in the finished film, and he was even offered to reprise his role in Revenge of the Fallen, which he had to refuse due to scheduling conflicts.

Patrick Donnelly

Zack Ward plays First Sergeant Patrick Donnelly. He is impaled and killed by Scorponok.

Colonel Sharp

Glenn Morshower plays Colonel Sharp, a marine who was killed during Blackout's attack in the beginning of the first film. He is credited as "SOCCENT sergeant".

Leo Spitz

Ramón Rodríguez plays Leo Spitz, Sam's whiny and cowardly college roommate who owns a website on conspiracy theories called www.TheRealEffingDeal.com. Rodríguez endured winds created by electrical fans while filming in Egypt, which resulted in him dislocating his shoulder and having to spend 45 minutes having sand flushed from his eyes. At some point, the character was supposed to be called "Chuck" and Jonah Hill was considered for the role.

Rodríguez was initially planned to be in Dark of the Moon in a bigger role, but he was dropped during early production.

Theodore Galloway

John Benjamin Hickey plays Theodore Galloway, the American National Security Adviser who believes the Autobots' presence on Earth is the reason for the Decepticons still remaining on the planet. However, this later evolves into irrational prejudice and contempt towards the Autobots. After Megatron's return and Optimus Prime's death, Galloway orders a shutdown on the partnership with N.E.S.T. and the Autobots and to have Optimus' corpse shipped to Diego Garcia. However, during the flight there, Colonel William Lennox straps him into a parachute, before opening the docking board, sending Galloway flying out of the plane. He lands in an uncharted desert, and angrily calls General Moreshower to complain.

R. A. Colan

Rainn Wilson plays Professor R. A. Colan, Sam's college lecturer who initially disliked Sam because of his bizarre behavior which upstaged Colan during the first day in class, but later respects him after learning of Sam's involvement in saving the world once again.

Bay based the character on one of his professors at Wesleyan University, who was rumored to be chatting up his female students.

In Rising Storm #4, Carly explains that Gould is not fond of fighting robots, and it is all "kids' stuff" to him.

Movie Plot

Dylan Gould is the CEO of Hotchkiss Gould Investments and the boss of Carly Spencer, Sam Witwicky's love interest. Dylan aids Sam in eventually finding a job at the fictional Acuretta Systems by sending Sam's future boss at Acuretta Systems, Bruce Brazos, a recommendation letter. It is later revealed that Dylan is in the service of the Decepticons, specifically Soundwave, aiding the Decepticons in hunting down and murdering anyone involved with the American and Russian Moon missions to the Ark; having discovered the Decepticons' presence during the original Apollo missions, Dylan's father made contact with them, father and son considering the war none of their concern and therefore considering it 'practical' to side with the winners. During a key movie moment, as Dylan reveals his involvement with the Decepticons to Sam, he places Sam under control of a simple Decepticon shaped as a watch and kidnaps Carly with the help from Soundwave. Dylan wants Sam to find out if Optimus Prime has a special plan to fight the Decepticons, telling Sam that Carly will die if he doesn't cooperate. Technically, Dylan learns that the Autobots have no plans, and orders Starscream to shoot their spaceship down to kill them all, though the Autobots have actually survived by landing down in the Atlantic Ocean. Before Sam is released, Sam swears he will kill Dylan for his actions. Dylan then heads to Chicago and the Trump Tower to witness the final phase of the Decepticon plan, taking Carly with him. Later in the movie, as Sam attempts to rescue Carly, Sam finds Dylan at his Chicago apartment and has him at gunpoint before Laserbeak manages to save Dylan by grabbing Sam and dropping him off the tower. Sam is saved and Dylan runs to tell the Decepticons that the Autobots are back, setting both up for their final fight. In their final fight, Dylan is somewhat annoyed that Soundwave is keeping several Autobots as prisoners, and convinces him to just kill them instead, which only led to Soundwave's death by Bumblebee. Eventually, Dylan reactivates the Control Pillar after it is temporarily disabled by Optimus Prime. Sam confronts Dylan; during their final fight near the Control Pillar, Dylan then taunts Sam that he doesn't have the guts to take him down at all, but Sam proves him wrong by knocking Dylan into the Control Pillar with a pole, electrocuting and thus killing him as Sam promised he would.

Books

In the novelization for Transformers: Dark of the Moon, Dylan appears to be very good at engineering and fixing cars, as he is able to fix Sam's new car within a minute. Also, when Sam kills him, he is incinerated by the energy of the pillar.

He is secretly working with Lockdown and Savoy and leading the operation to rid the Earth of all Transformers regardless of their faction.

However, acting behind the U.S. President's back, Attinger secretly ordered for the Autobots' elimination as well under the notion that his nation will never be safe until all Transformers are gone and create a new world order. To that end, not caring who dies in the process, be they innocent civilians or an entire city, Attinger forms a partnership with the Transformer bounty hunter Lockdown to capture Optimus Prime in return for a "Seed", a bomb that cyberforms a large area of land. He later gets involved in the battle in Hong Kong where he holds Cade at gunpoint, telling him that there are "no good aliens, or bad aliens", it's just humans or Transformers, since he feels the Autobots are still a threat to national security.

Seven Primes

Michael York, Kevin Michael Richardson, and Robin Atkin Downes voices the three members of Seven Primes, the first Cybertronians who came into distant galaxies looking for planets where they could build Sun Harvesters. It was during the Dynasty's rule that Sun Harvesters were not to be used in solar systems containing life. In 17,000 B.C.E., one of them defied his brothers' rule about destroying planets with life by powering up the Sun Harvester, an act that ignited a war and earned him the name The Fallen. To stop the Sun's destruction the remaining six stole and hid the Matrix of Leadership, sacrificing themselves to make a tomb of their own bodies, sealing the Matrix away. When Sam dies, he has a vision of the Dynasty and they tell him he has earned his destiny. The Dynasty then resurrects Sam, who uses the Matrix of Leadership to bring Optimus back to life and kills the Fallen. Their bodies resembles their brother, the Fallen, the same hands, body, heads and legs.

Lockdown's crew

Lockdown

Mark Ryan voices Lockdown, a ruthless Cybertronian bounty hunter and a former Decepticon who transforms into a grey 2013 Lamborghini Aventador LP 700-4 Coupe and speaks with a British accent. His robot mode slightly resembles Optimus Primal's appearance in Beast Machines, but also features a scar and he is capable of turning his head into a gun, and uses his hook (from the Revenge of the Fallen deluxe version), a sword and a booster shot. He was hired by The Creators, the unseen alien race who appeared in the beginning of the film, to bring Optimus Prime to them alive, wanting their "chest-board cleaned", and kill the remaining Autobots and Decepticons on Earth. Also, he made a deal with Attinger to give him the Seed when he captured Optimus Prime. He hunts and kills the Autobots, including Ratchet, Leadfoot (possibly Sideswipe, Mirage, Roadbuster and Topspin), and the remaining Decepticons on Earth. At some point in the past, Lockdown also captures the Dinobots and took over the Knight Ship, but the Dinobots are later freed by Optimus Prime. Lockdown is later killed by Optimus Prime, who vertically bisects him, avenging the deaths of Ratchet, Leadfoot and Lucas (and possibly Sideswipe, Mirage, Roadbuster and Topspin).

Lockdown also appeared as a Decepticon in the Revenge of the Fallen toyline, Cyber Missions and the Dark of the Moon video game, whose appearance was influenced by a combination of his Animated appearance, which he was voiced by Lance Henriksen. He is also the archenemy of both Ratchet and Arcee.

Mercenaries

The Mercenaries are a group of techno-organic humanoids of Lockdown. They use the Drone balls to roll and see anything aboard the ship, appeared to have red or green lights on their faces and reuse the Decepticon weapons. Several of them are killed by Cade, Shane and Crosshairs, while the surviving ones remained inside Lockdown's ship, as the two Drone balls are also killed by Cade on the Knight ship. They also used the Cybertronian starfighters, which first appeared in Dark of the Moon for Decepticons to first use in the battle of Chicago.

Steeljaws

The Steeljaws are the techno-organic canines and the minions of Lockdown. They are colored black and blue in the toyline. During the Autobots' aid in the Knight Ship, while hanging on the cables, they are killed by Cade Yeager and Bumblebee. They were originally called Wolves (appeared in Trading cards), but later these names were changed to Steeljaws. The Steeljaws do not transform in the film, they transform in the Age of Extinction toyline. Steeljaw was once an Autobot (as a lion later a dog), but later changed as a Decepticon.

Stupid Drones

These Stupid Drones are the wheeled minions of Lockdown who appeared to have cartoon-like eyes. They have claws and guns in the film, while the whips appeared in the concept art. In the Knight Ship, they tried to attack and kill Tessa, but fled. During the Autobots' aid in the Knight Ship, they tried to engage Cade and Shane, they retreated after Cade killed the mercenaries.

Just recently, after Michael Bay confirmed he would direct Transformers 5, he revealed an underwater scene of a crashed alien spaceship and a "cloaked dump truck transformer". It is unknown if the dump truck transformer will be an Autobot or a Decepticon.

Unused Transformers

It is revealed in the comics that Wreckage is the reason humans know so much about the Transformers. He is killed by Starscream for "treason".

Tidal Wave

Tidal Wave is a Decepticon who was originally supposed to appear in the first film.
