List of ''Transformers'' film series characters

The following is a list of characters featured in the Transformers film series, distributed by Paramount Pictures. Over 214 characters have appeared in the film franchise. For the list of the characters and their actors, see the list of Transformers film series cast and characters.

Autobots

In five films, 40 Autobots have appeared in the series. Most of them were members of NEST. By the end of Dark of the Moon, ten Autobots remained on Earth. After five years, the Transformers Reaction Force, Cemetery Wind, and Lockdown eliminated four of them. At the conclusion of The Last Knight, all surviving Autobots left Earth and returned to Cybertron.

• Primes
  • Sentinel Prime (voiced by Leonard Nimoy) is Optimus' mentor, the Prime of Dynasty of Primes, the first leader of the Autobots and the captain of the Ark who transforms into a red and black Rosenbauer Panther airport crash tender fire truck. He was the leader of the Autobots before Optimus took place, during the war for Cybertron. However, his intention to restore and rebuild 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, murdering Ironhide and kill most of the NEST 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 through his pride, 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 attempts to justify his actions, but Optimus, claiming Sentinel betrayed his own codes of honour, executes his traitorous mentor with Megatron's fusion shotgun.
  • Optimus Prime (voiced by Peter Cullen) is the second, leader of the Autobots after Sentinel, the last Prime of Dynasty of Primes, one of the Knights of Cybertron, keeper of the Matrix of Leadership and the narrator of the series.^[1] 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.^[2] 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.^[3] His performance consisted of much improvisation with Bay, and portraying the traditional heroism of the character as well as bringing a sense of humor.^[4] 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.^[5] 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.^[6] 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.^[7] Hasbro had previously rejected designs of Optimus which were too blue.^[7] Optimus' head was built on set as a prop.^[6] 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, despite Optimus stating that Sam should place the Allspark into his chest, sacrificing himself so Megatron would not be able to receive the Allspark. As a result, Cybertron can no longer be restored. Afterwards, Optimus and the other Autobots form an alliance with the humans and work closely with NEST. In Revenge of the Fallen, conceptual essays were made in an attempt to use his classic trailer for his power up mode,^[8] 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.^[9][10] 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.^[11] In Dark of the Moon, Optimus revives Sentinel Prime using the Matrix of Leadership and revealed he was the leader of the Autobots before him. But, Sentinel later betrays the Autobots and joins the Decepticons to restore Cybertron with the Pillars. During the battle in Chicago, Optimus kills Sentinel Prime (avenging Ironhide's death) along with all Decepticons, including the Driller, Shockwave, and finally Megatron. Optimus has finally added a trailer similar to his Generation 1 counterpart,^[12] and has been redesigned to look more heroic.^[13] The trailer contains enhanced weapons, a shield and a flight gear. Optimus loses his right 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 5700XE Custom Phantom semi-truck, which also gives him a more knightly appearance. However, he is being hunted by both the Transformer-hating Harold Attinger and a bounty hunter, Lockdown, who is working for the Creators to bring him to them. It is also revealed aboard Lockdown's ship that Optimus is a member of the Knights of Cybertron. Soon after his capture and in the battle of Hong Kong, Optimus tames the four Legendary warriors (the Dinobots) and rides Grimlock to fight Galvatron (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, Sideswipe, Dino and Lucas). He then sets the Dinobots free and ask his fellow Autobots to protect Cade and his family before taking the Seed into space and going after the Creators. In The Last Knight, he is seen in the beginning, frozen and floating past Jupiter, and later arrives at Cybertron, a dead planet. When he finds out his home is destroyed, he encounters and is captured by his maker, Quintessa, who wants to destroy Earth, which she reveals is an enemy planet called "Unicron". She tells Prime that he must retrieve the staff to rebuild the planet, and eventually brainwashes him to do her bidding. Prime's eyes turn purple and he becomes Nemesis Prime. Later, just as he is about to kill Bumblebee, Bumblebee speaks for the first time. The sound of his friend's long lost voice causes Prime to return to normal, shown by his eyes turning blue again. After defeating Quintessa and saving both worlds, Optimus and all Transformers finally leave Earth to return to Cybertron as it remains in orbit over Earth. He 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 that was later succeeded by a handheld Barrage Cannon in Dark of the Moon and Age of Extinction, and a handheld Energon axe first seen in his trailer in Dark of the Moon. In the fourth film, Optimus now carries a large handheld "Sword of Judgement" and shield cannon as a replacement for his energon swords, which he previously lost in his fight with Galvatron. In The Last Knight, he also has a pair of wrist-mounted retractable daggers much like his energon swords and a retractable pistol.
• Bumblebee (voiced by Mark Ryan in the first film and Erik Aadahl in the fifth) is an Autobot scout, and later Optimus' second-in-command after Ratchet's death in the fourth film. He was Sam's former guardian in the first three films. 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. 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". Additionally, it was revealed in the IDW comics tied in to the film that the loss of Bumblebee's voice a second time was the result of Starscream, who blasted him in an attempt to claim the fragment of the Allspark that would revive Megatron in Revenge of the Fallen. 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 had gone through some changes. His vehicle mode became Chevrolet Camaro 2011, and featured 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. It is likely that in Optimus Prime's absence, he held command of the Autobots during Optimus' flight into space to find his creators. In The Last Knight, Bumblebee gets his voice back and fixed, but is accidentally given a female voice. However, near the end, he speaks in his real voice to Optimus, turning him back to normal and snapping him out of Quintessa's brainwashing. Flashbacks reveal that he and Hot Rod were the first Autobots to arrive on Earth and fought alongside the Allied forces to fight the Nazi Party during World War II, and transformed to a Volkswagen Beetle similar to his G1 counterpart. He also knows Edmund from when they first met before he met Sam and has the ability to reassemble himself after being blown to pieces. In Transformers Universe: Bumblebee, Bumblebee will transform into a Volkswagen Beetle.^[14]
• Ironhide (voiced by Jess Harnell) is the Autobots' cantankerous but noble weapons specialist who transforms into a modified black 2006 GMC TopKick C4500 medium-duty truck. He has a rocket launcher and a plasma cannon on his forearms which in the first film, he threatens to blast Mojo, Sam's pet chihuahua. 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 first 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
• Jazz (voiced by Darius McCrary) is a lieutenant who develops a fondness for urban culture and music (specifically jazz) and he is 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 cartoon. "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.
• Ratchet (voiced by Robert Foxworth) is 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. For Dark of the Moon Ratchet had some changes done to his vehicle mode, which was painted green and white. 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, to the point of Optimus wanting to kill the humans responsible for Ratchet's death. Optimus avenges him by killing Hattinger and Lockdown
• Sideswipe (voiced by André Sogliuzzo in Revenge of the Fallen, James Remar in Dark of the Moon) is 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. In Dark of the Moon, Sideswipe's vehicle mode is upgraded into a convertible Corvette. He also seemed to be the second-in-command alongside Ratchet after Ironhide's death.
• 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. He solely 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.
• The Twins
  • Skids (voiced by Tom Kenny) is 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.
  • Mudflap (voiced by Reno Wilson) is 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.
• Arcee Sisters
  • Arcee (voiced by Grey DeLisle, holographic rider played by Erin Naas) is a female Autobot who transforms into a pink Ducati 848. She is killed by a Decepticon.
  • Chromia (voiced by Grey DeLisle, holographic rider played by Erin Naas) is one of Arcee's sisters who transforms into a blue 2008 Suzuki B-King.
  • Elita-One (voiced by Grey DeLisle, holographic riders played by Erin Naas) is another of Arcee's sisters who transforms into a purple MV Agusta F4 R312. She is killed by a Decepticon.
• Jetfire (voiced by Mark Ryan) is 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 walks with a cane, which doubles as a battle axe, which is also the landing gear for his transformation into the Lockheed. He later sacrificed his spark to allow Optimus Prime to utilize his components and weaponry to destroy the Fallen.
• Wheelie (voiced by Tom Kenny) is 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. In Dark of the Moon, he lives with Sam Witwicky, Carly Spencer, and Brains whom he becomes friends with. Later he and Brains participate in the Battle of Chicago. Although he was absent in Age of Extinction, Wheelie returned in The Last Knight hiding in a junkyard with Cade Yeager.
• Brains (voiced by Reno Wilson) 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. In Age of Extinction, Brains is captured by KSI, he lost his right leg and he is used to read and transfer data from fallen Autobots and Decepticons 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 cyberforming artifact known as the Seed for himself. Brains is later rescued by the Autobots during their raid to the KSI headquarters, and reveals that Megatron has possessed the KSI built Galvatron.
• Mirage (voiced by Francesco Quinn) is an Autobot spy who transforms into a red Ferrari 458 Italia and speaks with an Italian accent in Dark of the Moon. He has blades on his arms, and he resembles Bumblebee. In the film he was credited as Dino.
• Wheeljack (voiced by George Coe) is an eccentric Autobot scientist who speaks with an Irish accent, whose head design resembles Albert Einstein in reference to his genius 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 by Barricade when Soundwave orders his execution. He was credited in the film as Que/Wheeljack.
• The Wreckers are a trio of Autobots who transforms into NASCAR Sprint Cup Series Gen-5 Chevrolet Impala stock cars as disguises. Two represent Hendrick Motorsports and one represents Earnhardt Ganassi Racing. In contrast to the groups title, 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 engage in a counterattack on Sentinel Prime.
  • Roadbuster (voiced by Ron Bottitta) is the leader of the Wreckers who transforms into an armored version of the #88 Hendrick Motorsports AMP Energy/National Guard car driven at the time by Dale Earnhardt, Jr., and speaks with a Scottish accent. In The Last Knight, he makes a cameo with Topspin in Cuba.
  • Topspin (voiced by Steven Barr in the fifth) is one of the three Wreckers who transforms into an armored version of the #48 Hendrick Motorsports Lowe's/Kobalt driven by Jimmie Johnson, and appear to have claws on his hands. In The Last Knight, credited as Volleybot, he is seen in Cuba with Roadbuster under the protection of Seymour Simmons.
  • Leadfoot (voiced by John DiMaggio) is one of three the Wreckers who transforms into an armored version of the #42 Earnhardt Ganassi Racing Target car driven at the time by Juan Pablo Montoya, and speaks with a Cockney accent. In Age of Extinction, he appears in drone video footage, being attacked and killed by Cemetery Wind agents. Cade, who hacks a Cemetery Wind's spy drone, shows the footage to the Autobots, compelling Hound to salute his fallen friend.
• Hound (voiced by John Goodman) is an Autobot commando^[15] who transforms into a dark green Oshkosh Defense Medium Tactical Truck in Age of Extinction.^[16] His robot mode is modeled after a human commando with a bushy beard and bullet which he smokes like a cigar. Hound is the heavy weapons expert of the small group carrying various types of guns, as well as grenades and a knife, with him. Hound returns in The Last Knight as an olive green Mercedes-Benz Unimog military tactical ambulance and replaces Ratchet as Autobot medic.
• Drift (voiced by Ken Watanabe) is an Autobot tactician, a former Decepticon^[15] and a Triple Changer who transforms into a black and blue 2013 Bugatti Veyron Grand Sport Vitesse and a Cybertronian helicopter in Age of Extinction. He speaks with a Japanese accent. His robot is modeled after a samurai warrior with a braided beard. Drift is partnered with Dinobot Slug, who he rides into battle at the film's climax. Drift returns in The Last Knight as a black and red Mercedes-AMG GT.
• Crosshairs (voiced by John DiMaggio) is an Autobot paratrooper and sniper^[15] who transforms into a green 2014 C7 Corvette Stingray in Age of Extinction. His robot mode is modeled after a human paratrooper with goggles, sidearm machine pistols, and even a trench coat which can act as a parachute. He also rides with Dinobot Scorn into battle at the film's climax, and later nicknamed him "Spike". Crosshairs returns in The Last Knight as a green 2016 Chevy Corvette C7 Stingray.
• The Dinobots are the very large Cybertronian Knights who transform into giant mechanical spiked dinosaurs. In Age of Extinction, they were captured inside of their ship, which Lockdown took over as his prison ship until they were freed by Optimus in the end.
  • Grimlock is the leader of the Dinobots who transforms into a horned mechanical fire-breathing Tyrannosaurus, and formerly partnered with Optimus to ride on him.^[17][18]
  • Strafe is one of the Dinobots who specializes in assault infantry and transforms into a mechanical two-headed, two-tailed Pteranodon and formerly partnered with Bumblebee to ride on him.^[17][18]
  • Slug is the savage destroyer amongst the Dinobots who transforms into a mechanical spiked and bestial Triceratops and formerly partnered with Drift to ride on him.^[19]
  • Scorn is the Dinobots' demolition specialist who appears in Age of Extinction and transforms into a mechanical three-sailed Spinosaurus and formerly partnered with Crosshairs to ride on him and name him, "Spike".^[19] Scorn has a right arm and a left tail-whip arm.
  • Mini Dinobots are a group of small counterparts of Grimlock, Strafe and Slug. They appeared with Grimlock and Slug, living in Cade's junkyard.
• Hot Rod (voiced by Omar Sy) is Bumblebee's brother-in-arms and first seen transforming into a Citroën DS, then into a Lamborghini Centenario. He also speaks with a French accent to which he doesn't like and doesn't know how to get rid of. In The Last Knight he and Bumblebee helped fight the Nazi's during World War II. Years later, Sir Edmund Burton gave him the assignment of secretly watching over Viviane Wembly. He returned to Cybertron with others Autobots after Stonehenge's battle.
• Sqweeks (voiced by Reno Wilson) is a small Autobot in The Last Knight and Izabella's only friend who transforms into a turquoise Vespa (in the toyline). He struggles to communicate and has trouble transforming due to prior damage and has the ability to change his new arm into a gun.
• Cogman (voiced by Jim Carter) is a human sized sociopathic Autobot Headmaster who acts as Sir Edmund Burton's butler. He does not transform in The Last Knight, but he is mentioned to be a Headmaster by Edmund Burton. In the toyline, he transforms into an Aston Martin DB11.
• Canopy (voiced by Frank Welker) is an Autobot refugee who can pose himself as a shielding pile of rubble. He shares the same body-type as Long Haul possibly meaning that his alternate form is a Dump Truck. Like Sqweeks, he is a friend of Izabella. In The Last Knight he is mistakenly shot down and killed by TRF, believing him to be a Decepticon trying to harm kids who had trespassed into a restricted zone.
• Daytrader (voiced by Steve Buscemi) is an Autobot scavenger who transforms into a cloaked rusty Mercedes-Benz LK Model 1920 dump truck. He is seen in The Last Knight arriving at Cade Yeager's junkyard after salvaging old Transformers parts from old battles.
• Trench is an Autobot who resembles the same body of Scrapper and transforms into a yellow front end loader excavator. He made a cameo in The Last Knight transforming when the Decepticons are approaching Cade's junkyard, forcing Cade, Autobots and the others to escape.
• Bulldog (voiced by Mark Ryan) is an Autobot warrior who transforms into a Mark IV tank. He was a veteran from World War II and suffers from "robot dementia".
• Other Autobots
  • An elderly war plane Autobot who transforms into a Hawker Hurricane, resembling Jetfire. He appears in The Last Knight within Edmund's castle attempting to transform in response to TRF's arrival but his old age causes him to collapse.
  • An HMS Alliance submarine Autobot in The Last Knight who doesn't transform on screen, but is mentioned to being a Transformer.

Decepticons

In five films, 48 Decepticons have appeared in the series.

• The Fallen (voiced by Tony Todd), formerly Megatronus, is a rogue Prime of Dynasty of Primes, the founder and the first Decepticon, and Megatron's mentor. 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. Luckily, his brothers stopped him and took the Matrix and hid it from him. Years after his betrayal, he is shown aboard the Nemesis, which was crash landed on one of Saturn's Moons, in some kind of stasis. 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.^[20] 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 utilize his components. After Rachet and Jolt fuse Optimus with Jetfire's weaponry, Optimus Prime destroys the Sun Harvester and the Fallen is finally killed by Optimus Prime. The writers selected The Fallen after looking through various cartoons and comics for new characters, because he was the most "elemental" villain.^[21] At some point, Leonard Nimoy^[22][23] and Frank Welker^[24] (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 (voiced by Hugo Weaving in the first three and Frank Welker in the fifth) is the iron fisted, tyrannical, ruthless, and maniacal leader of the Decepticons, Optimus Prime's archenemy, but brother, and an apprentice of his master, The Fallen.^[25] 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.^[7] 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.^[6] 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".^[7] 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.^[7] Optimus calls Megatron his brother; Cullen interpreted this line literally,^[26] but while the writers state this was the case in early drafts, they consider the line in its final context to be metaphorical.^[27] 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 apprentice of the Fallen, who is the founder of the Decepticons.^[28] Despite Michael Bay's initial claims of him not returning after he was killed and thrown into the Laurentian Abyss in the first film,^[29] 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. He deactivates Optimus Prime and later pursues Sam Witwicky for vengeance and to obtain the AllSpark knowledge the human possess within his mind. In Egypt, 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.^[30] When reviving the character, the writers chose not to rename him Galvatron so as to not confuse the general audience.^[24] In Dark of the Moon, 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 and goes into hiding in Tanzania.^[31] After Optimus Prime destroyed half of his face in Revenge of the Fallen, Megatron sometimes hides it by using a cowl.^[32] Instead of using a Fusion Cannon integrated into his arm, he wields a hand-held fusion shotgun similar to a Lupara. 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, but the latter sees through the ruse and attacks his eternal foe, tearing off Megatron's head with a battle axe. In Age of Extinction, Megatron's head is seen in at KSI, where a captive Brains discovers that the Decepticon leader's consciousness is still alive and in a deep stasis. Megatron's mind silently manipulates Joshua Joyce and his creation of the artificial Transformers, including a Galvatron model where he accepts the name as his new identity and is able to take control of other artificial Transformers as well.^[15] Megatron returns in The Last Knight. Concept art for him that has been released has revealed him to resemble a darker, more monstrous version of Optimus Prime's knight form, with a similar faceplate to Optimus's own and a horned helmet vaguely resembling his G1 incarnation helmet. He is further revealed to have his signature forearm-mounted fusion cannon and a knight's sword like Optimus, further emphasizing the enmity between the two. His vehicle mode for the film has been revealed to be a Cybertronian jet, similar to G1 Cyclonus' jet mode.^[33] In the film, he searches for the talisman to find Quintessa's staff. Later in the final battle on Cybertron, he is defeated by Optimus when Optimus cuts off his right arm as he did in Revenge of the Fallen, and is kicked through a wall, sending him falling back to Earth.
• Starscream (voiced by Charlie Adler) is 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.^[34] Despite being a popular character, his role is limited because of the film's running time.^[27] A post-credits scene of him escaping Earth was added because audiences at test screenings wanted to know what happened to him.^[6] This keeps the character's role as the powerful and technologically advanced air commander. Starscream has a rather negative relationship with Megatron.^[7] 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.^[35] In Dark of the Moon, Starscream is finally killed by Sam Witwicky who blows off his head with a small bomb that was designed and given to him by Que. In The Last Knight, his head was seen being boasted by Daytrader, who claims he found it in Buffalo, New York. Later it is seen being held by Megatron reminiscing about him.
• Blackout is a first-strike Decepticon and the 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 eliminates most of the humans, except Lennox and Epps. He later attacks Mission City where he tries to kill Sam and get the All-Spark. Blackout is killed by human fighter jets and Major Lennox, who shoots him in his spark.

In the beginning, he is seen attached on Blackout's back, and during Blackout's attack on Qatar's military base, the former deploys him with Scorponok jumping into the sand. After being damaged by the gunships, Scorponok retreats beneath the sand, and does not appear for the rest of the film, while his tail was recovered by Lennox's team for study. In Revenge of the Fallen Scorponok reappears in the final battle in Egypt, where he disembowels and damages Jetfire, only for Jetfire to crush him under his fist, finally killing him.
• Barricade (voiced by Jess Harnell in the first and fifth, and Frank Welker in the third film) is a Decepticon scout who transforms into a black Saleen S281 police car, whom Frenzy guides to Sam. He is shown as Bumblebee's rival in the first film.^[36] He was modeled after the G1 Autobot Prowl, because the writers thought a Decepticon displaying authority would use the police car form.^[7] 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.^[37][38] Barricade was soon defeated by Bumblebee, but reappeared when Starscream calls the Decepticons to mobilize. Barricade later returned in Dark of the Moon. He appears in the Battle of Chicago last seen being shot in the head by a group of soldiers after a boom-stick blew off one of his legs.

In Revenge of the Fallen, Frenzy's head is seen in the basement of Simmons' mother's deli.
• Bonecrusher (voiced by Jimmie Wood) is a very hate-fueled and a cantankerous Decepticon who transforms into a Buffalo H Mine-Protected vehicle. The animators modeled his fighting styles on hockey and football players.^[6] 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.^[7][40] 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 by Optimus Prime, after his right arm is cut off. In Revenge of the Fallen, аfter reset its remains on the bottom was rebuilt as Megatron, participated in the final battle in Egypt, along with Starscream attacking Arcee and their attacks killed Chromia and Elita 1, when they were trying to protect Sam.

• Soundwave (voiced by Frank Welker) is the Decepticon Communication Officer and one of Megatron's most loyal lieutenants.^[42][43] In Revenge of The Fallen he attaches himself to a military satellite to coordinate the Decepticons' movements around the world. The concept artists also designed an Earth form of a Chevrolet Silverado for him to upgrade into, which was ultimately dropped.^[44] 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.^[45][46] 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.
  • Ravage (vocal effects provided by Frank Welker) is a Decepticon infiltration expert and a minion of Soundwave that resembles a large one-eyed Jaguar^[47] and is a fierce hunting machine.^[48] He is later killed by Bumblebee in Revenge of the Fallen when Bumblebee rips out his spine during the battle in Egypt. Early in production, he was meant to adopt a fish/submarine-like form right after he first falls into the ocean,^[49] and while this was ultimately left out of the movie, it can still be seen in the film's toyline.^[50]

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.^[65] The fan art impressed Bay enough to hire him on to the film.^[66] After the air strike in Egypt from long Haul escaped only his head became a drone Igor. 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.^[67]

Reedman appears when at a certain point in the film, Ravage is seen deploying a load of marble-sized "microcons"^[8] 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.

• Shockwave (voiced by Frank Welker) is a Decepticon scientist.^[73][74][75] He is killed in the Battle of Chicago by Optimus. Shockwave transforms into a Cybertronian self-propelled artillery vehicle. 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.^[76] 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.^[77]
  • The Driller is Shockwave's pet; a giant, tentacled Mongolian death worm-like Cybertronian creature, which is used for drilling purposes. It is also Cybertron's most feared predator.

They were built with the metal extracted from the remains of the dead Transformers. They also modeled after both Autobots and Decepticons. They were originally mindless drones remote-controlled by humans, but later were granted autonomy by the Megatron possessed Galvatron, organizing them into a new 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 in an attempt to retrieve the Seed. His army is soon destroyed along. However, Galvatron survives vowing that he will meet Optimus again, and declares that he is reborn.

According to Roberto Orci, the character of Sam was written as a "2007 version of Marty McFly".^[91] Sam Witwicky did not return for the fourth film; his character is later replaced by Cade Yeager (portrayed by Mark Wahlberg).^[92][93] LaBeouf makes a brief cameo as Witwicky in a photograph in Burton's mansion in Transformers: The Last Knight.^[94]

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. Sam Witwicky is never seen again after Dark of the Moon, and his fate is ultimately unknown.

In The Last Knight, a photo of Sam is seen as part of the Witwiccan Order gallery along with Sir Edmund Burton (played by veteran actor Anthony Hopkins), who is the last surviving member of the "Witwiccan Order". However, due to Burton being the last surviving member, it can be implied that Sam may be dead at this point.^[97]

Toys

• Transformers Deluxe Barricade with Frenzy Screen Battles: First Encounter (2007)

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.^[98]

• Revenge of the Fallen Human Alliance Bumblebee with Sam Witwicky (2009)

A larger (between Voyager Class and Leader Class size) figure than the Deluxe Class figure with a 2-inch-tall figure of Sam, which can ride inside Bumblebee.^[99]

• Transformers Human Alliance Bumblebee with Sam Witwicky (2010)

A re-release of the Human Alliance figure with a remold of the Sam figure; this one wearing a white shirt instead of a black one. In addition, the Sam figure lacks the upper torso articulation of the previous version.

Portrayed by	Megan Fox
Information
Species	Human
Gender	Female
Occupation	Student Ally to the Autobots (formerly) 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, but 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 nor any of the other films due to Megan Fox being fired.^{[101][102][103]} Because of this, the film's storyline says that Sam and Mikaela broke up and went their separate ways.

In Transformers: Dark of the Moon, Carly Spencer (portrayed by British model Rosie Huntington-Whiteley) is Sam's second girlfriend, with whom he lives. She is feisty, kind, clever, jolly, sarcastic, and loyal.

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

Carly Spencer appears in the book Transformers: Dark of the Moon: The Junior Novel.^[96]

Movie plot

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 by pushing his buttons and taking advantage on his arrogance, leading to the deaths of Megatron and Sentinel. Carly reunites with Sam after the battle and they admit they love each other. Carly is never seen again after Dark of the Moon and her fate is unknown.

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.^[108] She had previously worked with the film's director, Michael Bay, on a Victoria's Secret commercial.^[109] MTV Networks' NextMovie.com named her one of the 'Breakout Stars to Watch for in 2011'.^[110] Prior to the film's release, she won the "Female Star of Tomorrow" award at the 2011 CinemaCon Awards.^[111] Critics were highly critical of the acting of Huntington-Whiteley and co-star Shia LaBeouf. Peter Travers stated the two "couldn't be duller."^[112] 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."^[113] 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."^[114] Baz Bamigboye gave his review of the film the title 'Come back Megan Fox, all is forgiven...'.^[115] 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."^[116]

Seymour Simmons

Seymour Simmons (portrayed by John Turturro) is a former arrogant and paranoid Sector 7 agent and Sam's unlikely ally turned friend 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.^[6] 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.^[27] 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.^[6]

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 broken his leg during the Highway chase by Crowbar and is revealed to have had a relationship with Charlotte Mearing.

Simmons returned in The Last Knight. Simmons is shown to be hiding out in Cuba along with the remaining Wreckers Topspin and Roadbuster, as Cuba gives asylum to Autobots and their supporters. Simmons gives information to Edmund Burton, using what Simmons learns from informants in the government. At one point, Simmons asks to be initiated into the Witwiccan Order, which Burton does.

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.^[117] 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.^[118] He and Judy leave Washington DC before the final battle.

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

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 a human collaborator of the Decepticons, specifically Soundwave, declaring he wanting to survives in the upcoming war, 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 with 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.

There, he finds and buys parts to send his young daughter to college until he discovers a rusty truck, which is damaged. He uses Lucas' money to buy the truck. Later, he discovers that the truck is not a normal vehicle, but a transformer. Cade, eager to learn more about it and its technological secrets, keeps the truck despite Lucas and Tessa's protests. When fixing the truck, Cade removes a live missile from the truck's power core, and it transforms, revealing it to be the Autobot leader Optimus Prime, who is badly damaged and weak from an attack by humans. Cade manages to calm him down, and he agrees to repair Optimus.

After Bumblebee and Drift take Cade out of Attinger's interrogation, they are pursued by Galvatron and Stinger, and Lockdown appears, seeing as he takes Optimus and Tessa with him. It was with Cade and the Autobots to save them by going to the Lockdown ship. Then in finding her, they escape with Bumblebee and Crosshairs from the mercenaries. In Hong Kong, they search for Joshua with the Seed and fall off the ship with Bumblebee and Hound. After him and the others are attacked by Savoy, Cade lets them escape so that he will kill Savoy. In the battle, Cade leaves him with his daughter to protect her and to go with Bumblebee, but when Shane hears Tessa that he does not want to leave his father, they decide to return to help him and Optimus in kill Lockdown.

He originally works with Harold Attinger to obtain the Seed (a cyberforming bomb) from Lockdown in exchange for Optimus Prime. He also arrogantly claims the Autobots are no longer needed as a means of justifying his use of dead autobots for KSI's project, causing them to leave, hurt and betrayed. However, upon unleashing Galvatron and seeing him malfunction during a pursuit of the Autobots at Attinger's insistence, as well as Attinger's complete and despicable disregard for civilian safety as well as his insatiable greed for fame and fortune for ridding the world of Transformers, Joshua begins to change his views. Added to this, after talking with Cade Yeager, he soon realizes that Galvatron has been manipulating him into bringing the Seed to him. When Galvatron activates himself and brings to life the other KSI-created Decepticons, Joshua flees with the Seed, siding with Cade Yeager and the Autobots to keep it from Galvatron and Attinger both. After Optimus Prime and the other Autobots defeat Galvatron's forces and Lockdown, Joshua watches with Cade and his family as Optimus leaves earth. He also agrees to help Cade and his family rebuild their home due to Attinger and Lockdown's destruction of it as part of his reparations to them.

Cemetery Wind

The Cemetery Wind is a secret black-ops unit of the Central Intelligence Agency and works with KSI. They were asked to hunt down the Decepticons only, but without the President's and their own agency's knowledge, Cemetery Wind have secretly went rogue by eliminating the Autobots (who were granted asylum after their alliance with the military ended) and due to Attinger's belief that all Transformers were menaces to humanity, no matter their faction. To that end, they were also willing to eliminate any potential human allies the Autobots might have had, such as the Yeager family. After the final battle of Hong Kong and the deaths of Attinger and Savoy, Cemetery Wind and its nefarious dealings have been presumably exposed and shut down, eventually labeled as a terrorist organization.

However, the remnants of the group were reformed into the Transformers Reaction Force (TRF) in The Last Knight by mercenaries who wanted to see all Cybertronians destroyed.

Attinger's other goal is to gain fame and fortune for his work in ridding the world of all Transformers. 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, hoping that it will allow him to reap immense profits from his business "partner" Joshua Joyce and KSI's use of it to build a man-made army of Transformers to command. Joyce however betrays Attinger upon realizing just how ruthless and murderous the CIA operative is and runs away with the Seed when Galvatron comes after it. He later gets involved in the battle in Hong Kong where after watching Savoy die at Cade's hands and failing to obtain the Seed from Joyce, 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.

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.
