Characters[]

The following is a list of characters featured in the Transformers film series, distributed by Paramount Pictures, and its related media appearances. Over 214 characters have appeared in the film franchise.

Autobots[]

In the first five films, 40 Autobots have appeared in the series. By the end of Dark of the Moon, ten Autobots remain on Earth. Five years later, half of the Autobots have been eliminated by Cemetery Wind, Lockdown and TRF. By the end of The Last Knight, all surviving Autobots (Optimus Prime, Bumblebee, Hound, Drift, Crosshairs, Cogman, Daytrader, Hot Rod, Sqweeks, Wheelie, Topspin, Roadbuster, Brains, Mirage/Dino, Trench, Bulldog, Grimlock, Slug, the Mini Dinobots, HMS Alliance Autobot and the Knights of Iacon) finally leave Earth and return to Cybertron.

• Primes – The title of Prime is bestowed upon the civilian and spiritual leader of Cybertron. Among the known Primes are:
  • Optimus Prime (voiced by Peter Cullen) is the leader of the Autobots, the last descendant of the Dynasty of Primes, one of the Guardian Knights, keeper of the Matrix of Leadership and the narrator of the series. He transforms into a 2007 red and blue Peterbilt 379 semi-trailer truck in the first three films, a rusty 1973 Marmon HDT-AC 86 semi cab-over truck in the beginning of the fourth film, and later a blue and red Western Star 5700 OP Phantom semi-truck. Optimus Prime is armed with an ion blaster, a shotgun, energon blades, an energon axe, energon hooks, bladed knuckles, a shield, and flight gear. The flight gear features machine guns and missile launchers. In the first film, Optimus Prime arrives on Earth with Ratchet, Ironhide, and Jazz trying to find the AllSpark. At Mission City, he kills Bonecrusher and battles Megatron, but Sam pushes the AllSpark into Megatron's chest, killing him and destroying the cube. As a result, Cybertron can no longer be restored. Afterward, Optimus and the other Autobots form an alliance with the humans and work closely with NEST. In Revenge of the Fallen, Optimus is killed (impaled from behind) 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. 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 finally has a trailer similar to his Generation 1 counterpart,^[5] and has been redesigned to look more heroic.^[6] The trailer contains enhanced weapons and flight gear. Optimus loses his right arm to Sentinel Prime at the film's climax. In Age of Extinction, he is being hunted by both the Transformer-hating Harold Attinger and a Cybertronian assassin and bounty hunter, Lockdown, who is working for the Creators to bring him to 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 Harold Attinger and Lockdown (avenging the deaths of Ratchet, Leadfoot, and Lucas among others). He then sets the Dinobots free and asks his fellow Autobots to protect Cade and his family before taking the Seed into space and going after the Creators. In The Last Knight, when frozen and floating past Jupiter, he arrives at Cybertron, now a dead planet. There he finds Quintessa, the Prime of Life. She brainwashes Optimus to do her bidding and gives him a red marking to achieve her goal of destroying Earth, which she reveals is an ancient enemy planet called "Unicron". She tells Prime that he must retrieve her staff to rebuild Cybertron. Prime's eyes turn purple, his paint scheme turns to black, and he becomes Nemesis Prime under Quintessa's control. Later, just as he is about to kill Bumblebee, Bee speaks for the first time in 10 years. The sound of his friend's long lost voice causes Prime to return to normal, shown by his eyes turning blue again and his red marking disappeared. He rides with Dragonstorm into battle. After brutally seemingly slaughtering Quintessa and saving both worlds, Optimus and all Autobots return to Cybertron but don't actually leave Earth as Earth and Cybertron are now joined as one planet. Optimus Prime reappears in Bumblebee, in which he is designed more like his G1 self. In the film, he leads the Autobots against the Decepticons trying to take over Cybertron, but is forced to retreat when Decepticon reinforcements led by Soundwave and Shockwave attack them. Realizing that Cybertron has fallen, he orders all Autobots to get to their escape pods. However, he has given Bumblebee the task to protect Earth and set up a base for them before being attacked by Ravage and other Decepticons. In the end of the film, he praises Bumblebee for keeping Earth safe.
  • Sentinel Prime (voiced by Leonard Nimoy) is another member of the Dynasty of Primes, the first leader of the Autobots and the captain of the Ark who transforms into a red and black Rosenbauer Panther 6x6 airport crash tender fire truck. Sentinel Prime is armed with a cosmic rust cannon, a double bladed Primax blade that can be folded into one and a shield. He is the leader of the Autobots before Optimus succeeds him, during the War for Cybertron. He makes a deal with Megatron to restore and rebuild Cybertron to bring the Pillars (including the Control Pillar) to Earth's moon and later to Chicago, in order to transport Cybertron to Earth/Unicron's atmosphere on Quintessa's behalf. However, after Bumblebee and Ratchet destroy the Pillars and Megatron interferes with his fight against Optimus, Sentinel gets his brains blown out by Optimus for his betrayal. His head makes a cameo appearance at the KSI building in Age of Extinction, it is not converted into transformium.
• Bumblebee (voiced by Dylan O'Brien in Bumblebee, Mark Ryan in the 2007 film and the Revenge of the Fallen video game, Erik Aadahl in The Last Knight) is an Autobot scout, later Optimus' second-in-command after Ratchet's death in the fourth film, Hot Rod's brother-in-arms and Sam's former guardian in the first three films. Bumblebee is armed with a plasma cannon that is capable of selective fire. He also uses radio soundbites after losing his voice on Cybertron, his throat begins healing after Ratchet fires a regenerative laser. Bumblebee transformed into a 1977 Chevrolet Camaro, and upgrades into the 2006 model. Later at the end, his voice has spoken again. 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". He also transforms into a new 2009 Chevrolet Camaro. For Dark of the Moon, his vehicle mode became a customized 2011 Chevrolet Camaro, featuring a new body kit and paint job. For Age of Extinction, Bumblebee is now a modified vintage 1967 Chevrolet Camaro, and later 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. In The Last Knight, Bumblebee is now a modified 2016 Chevrolet Camaro, and gets his voice back and fixed, but is accidentally given a female voice. However, near the end, his real voice speakes again 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 Mercedes-Benz Typ 320 (This backstory was later retconed in the spin-off/reboot movie, where it reestablished that Bumblebee first arrives on Earth in 1987). 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 Bumblebee, he is redesigned to look like his G1 counterpart and will transform into a Volkswagen Beetle. In the film, he lands on Earth after Cybertron falls to the Decepticons. After his synthetic voice communicator is ripped out and destroyed by Blitzwing, Starscream's slave, he manages to escape and befriends Charlie Watson, an 18-year-old girl in Brighton Falls, California. He comes into conflict with Decepticons Shatter and Dropkick, who are looking for him in regards to Optimus Prime's location. After being captured by Sector 7, led by Jack Burns, Shatter and Dropkick interrogate him and plan to bring a Decepticon army to Earth, intent on destroying it. Bumblebee manages to kill Shatter and Dropkick and he and Charlie part ways so he can be with Optimus Prime and the other Autobots.^[7]
• Jazz (voiced by Darius McCrary in the first film, Andrew Kishino in Transformers: The Game) is the first lieutenant of the Autobots and Optimus Prime's second-in-command who transforms into a modified silver Pontiac Solstice Custom Hardtop GXP. Jazz is armed with a crescent blaster. He is later killed by Megatron during the battle in Mission City where his body ripped in two.
• Ironhide (voiced by Jess Harnell in the films, Mark Ryan in Transformers: The Game) is the Autobots' English-accented weapons specialist who transforms into a modified black 2006 GMC TopKick C4500 medium-duty truck. Ironhide is armed with shell cannons. In Dark of the Moon, he has a new rifle and a new rocket launcher. In Revenge of the Fallen, Ironhide takes down the Demolishor with Prime in Shanghai, then later takes over as Autobot Leader when Optimus is killed by Megatron in the forest. He leads the Autobots in the desert battle and helps Sam get to the pillars where Optimus lies. He is heavily damaged and forced to drop his heavy cannons during an airstrike. In Dark of the Moon, he helps Sideswipe to take down the Decepticon Dreads, as they chase Sentinel to NEST. But Sentinel Prime reveals his true color and betrays the Autobots, shooting unaware Ironhide twice in the back with his cosmic rust cannon, then once more in the chest, the Autobot warrior crumbling into dust in seconds. He was later avenged by Optimus when he kills Sentinel. Ironhide also appeared in a photo in Age of Extinction and The Last Knight.
• Ratchet (voiced by Dennis Singletary in Bumblebee, Robert Foxworth in the film, Fred Tatasciore in Transformers: The Game) is the Autobots' medical officer who transforms into a Los Angeles Fire Department Search and Rescue 2004 Hummer H2. Ratchet is armed with heavy machine guns and a saw. For Dark of the Moon Ratchet's alt mode is given a new paint job of green and white. In Age of Extinction, he has his spark torn out by Lockdown and his corpse is taken to KSI, melting his head to build remote controlled Transformers. His death was later avenged by Optimus when he killed Attinger and Lockdown. Ratchet reappears in Bumblebee, looking like his G1 self.
• Sideswipe (voiced by André Sogliuzzo in Revenge of the Fallen, James Remar in Dark of the Moon, Fred Tatasciore in Transformers: The Game, John DiMaggio in the Revenge of the Fallen video game) is the Autobots' combat instructor who transforms into a silver Chevrolet Corvette Stingray concept. Sideswipe is armed with Cybertanium blades. Having wheels for feet, he moves around skating. In Dark of the Moon, Sideswipe's vehicle mode is upgraded into a convertible Corvette. While Sideswipe goes completely unmentioned in Age of Extinction, he has been killed by Cemetery Wind or Lockdown.
• Jolt is a technician Autobot armed with a pair of electro-whips who transforms into a blue Chevrolet Volt. He appears in Revenge of the Fallen, where he used his whips to fuse Jetfire's parts onto Optimus. Jolt did not appear in Dark of the Moon as he was killed by Shockwave before the film was released.
• The Twins – The Twins are the result of a split Spark that resulted in two Autobots.
  • Skids (voiced by Tom Kenny) is an Autobot infiltrator and Mudflap's twin who transforms into the front half of a white/pink Dodge ice cream truck, and later a green Chevrolet Beat. He has an oversized right arm. Skids is armed with a grappling hook.

• Sqweeks (voiced by Reno Wilson) is a small Autobot and Izabella's only friend who 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. Despite his status, his Headmaster ability is not demonstrated. He also has the ability to drive cars to escort Burton to safety and tends to go on a road rage when trying to evade capture by MI6 and British TRF forces. He can also shoot a missile from his mouth, as shown when he destroys a TRF SUV, causing it to crash.
• Canopy (voiced by an uncredited actor) is an Autobot refugee who can pose himself as a shielding pile of rubble and is friends of Izabella and Sqweeks. 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. As Izabella vowed to repair him, Canopy implored Izabella to run and thanks her for the companionship.
• 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 arriving at Cade's junkyard after salvaging old Transformers parts from old battles for profit and finding a ship for the Autobots to leave. Daytrader is similar to Wreck-Gar.
• Trench is an Autobot who resembles the same body of Scrapper and transforms into a yellow Caterpillar 320 excavator. He made a cameo in The Last Knight, transforming when the Decepticons are approaching Cade's junkyard, forcing Cade, the Autobots and the others to escape. His fate is unknown.
• Burton's Autobot Allies – The following Autobots are allied with Sir Edmund Burton and Cogman.
  • Bulldog (voiced by Mark Ryan) is an Autobot who acts as a sentry for Sir Edmund Burton's castle and transforms into an army green Mark IV tank. Bulldog suffers with "robot dementia".
  • Lieutenant (voiced by Mark Ryan) resembles a tweaked version of Jetfire and transforms into a Supermarine Spitfire (although this is not shown). He made a cameo in The Last Knight within Edmund's castle in response to TRF's arrival, but collapsed.

• Cliffjumper (voiced by Andrew Morgado) is an Autobot who appears in Bumblebee.^[13] Like some different versions of Cliffjumper, he is a retool of Bumblebee with a new head design. While on the Moons of Saturn, he is killed by Dropkick after refusing to reveal the location of Optimus Prime and instead asking B-127 where the location of Optimus Prime is. His death is similar to his Prime counterpart in which he got sliced in half by Megatron, while in the "Bumblebee" film, he is sliced by Dropkick. Chronologically, he was the first Autobot to be killed and die onscreen. He would later be avenged by Bumblebee, who tears Dropkick apart with a chain and crushes Shatter in a flood.
• Brawn (voiced by Kirk Baily) is an Autobot who made an appearance in Bumblebee. Brawn looks like his G1 self.

Decepticons[]

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

• The Fallen (voiced by Tony Todd in the film, James Arnold Taylor in the video game), formerly Megatronus, is a rogue Prime of the Dynasty of Primes, the founder and the first Decepticon (the second known born enemy of Earth from Cybertron after Quintessa), and Megatron's mentor. In 17,000 B.C., he and his brothers set out into the universe seeking distant suns to harvest to create Energon by building Star Harvesters, but the Fallen defies his brothers rule to “Never destroy a planet with life,” by building a Star Harvester on Earth in order to destroy both the planet and its sun. He then steals the Matrix of Leadership, the only thing that can turn on the machine. 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 void scepter as a melee weapon.^[14] 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 with help from Soundwave 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 Harvester, declaring revenge is his at last. However, as the Sun Harvester charges, Jetfire sacrifices himself in order to let Optimus utilize his components.

He is the only Constructicon who has no toy in the Transformers Studio Series line, as of 2020, besides Demolisher, who even then will be likely to come out as a repaint of Scavenger. Even if the toy is released, there will probably be no way to connect him with Skipjack/Rampage since they already make a full leg. He may connect and wrap around the ankle, or just be a stand-in remold for Long Haul. This would be inaccurate, because he is smaller than Long Haul.

Shockwave returns in Bumblebee.^[41] 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.^[42]
  • The Driller is Shockwave's pet. It is a giant, tentacled Mongolian death worm-like Cybertronian creature, which is used for drilling purposes. It is also Cybertron's most feared predator.

Million of years later, they send their assassin and bounty hunter Lockdown to Earth—to bring Optimus Prime alive, wanting their "chessboard cleaned" and wanting him to rebuild Cybertron, and kill the remaining Autobots and Decepticons. They appear to be hostile and consider the intermingling of species to upset the cosmic balance. At the end after Lockdown was killed, Optimus flies into space from Earth, stating that he is coming for them with the Seed. They don't appear in body, but a pink, organic-looking hand is briefly seen inside of one of their ships.

She has a Staff with the power of Cybertron, but her Knights betrayed her and stole her Staff and hidden on Earth. Quintessa appears to have the ability to create balls of blue electricity and throw them as projectiles. After Cybertron was destroyed in Dark of the Moon, she plans to destroy Earth to rebuild the planet with Optimus Prime (who was coming for questions on why his Creators want him back), who formerly becomes "Nemesis Prime", and Megatron. After failing her plan to retrieve her staff, she disguised herself as a human offers the Humans on how to kill Unicron.

When a group of kids enter a war torn area of Chicago to see some "dead robots", they are frightened by a dying Knight awakening while looking in his crashed ship. Cade discovers a Knight, who refuses treatment and gives Cade the talisman before dying.
  • Skullitron is a Guardian Knight who only appeared in The Last Knight. When Cade and Viviane arrive to find the staff, the TRF arrive after Cade accidentally awakens Skullitron. He attacks everyone present to protect the staff, but is shot multiple times by the TRF and falls into a large crevice to his death.
• Unicron is the Chaos Bringer that formed Earth and Cybertron's ancient enemy who finally appeared in The Last Knight. His six horns are around the planet when Sir Edmund Burton searched a book with pictures of Unicron and Cybertron itself. Later, Quintessa seeks to destroy Unicron, so that Cybertron will live. Two worlds begin to collide, but two worlds are saved by the Autobots and the Knights who retrieved the Staff and vanquished Quintessa. However, unaware to them, Quintessa survived and disguised herself as a Human and continues her plans to destroy him.
• A Vatti Transformer is a Cybertronian who only appeared when Daytrader was collecting the remain pieces. It transformed into one with two parts until it was killed by Bumblebee.

• 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 gone rogue by eliminating the Autobots and due to Attinger's belief that all Transformers were menaces to humanity, no matter their faction. After the final battle of Hong Kong and the deaths of Attinger and Savoy, Cemetery Wind was disbanded for military crime and was replaced with the TRF.
  • Harold Attinger (portrayed by Kelsey Grammer) is a rogue CIA operative who is the nefarious founder of the black ops division Cemetery Wind. Later in the battle of Hong Kong, he is finally killed after being shot in the chest by Optimus Prime, saving Cade's life, before Optimus kills Lockdown.
  • James Savoy (portrayed by Titus Welliver) is a ruthless, corrupt field leader of the CIA black ops division Cemetery Wind and second in-command of Harold Attinger. He lost his sister in the battle of Chicago, which might be one of the reasons why he supported the idea of exterminating the transformers species and not care which side they're on. He later got killed by Cade Yeager who knocked him off a building during their fight.
• Lockdown (voiced by Mark Ryan in the film,^[8] Gregg Berger in Rise of the Dark Spark) is a ruthless, cold hearted and barbaric Cybertronian assassin and bounty hunter who transforms into a grey 2013 Lamborghini Aventador LP 700-4 Coupe and speaks with a Cockney accent.^[11] His robot mode slightly resembles Optimus Primal's appearance in Beast Machines,^[10] but also features a scar on his left face and he is capable of turning his helmet into a gun, and uses his hook (from the Revenge of the Fallen deluxe version), a sword and a booster shot. In the film, Lockdown is working for Quintessa to bring Optimus Prime to rebuild Cybertron. He made a deal with Attinger (though he does have a slur towards humans, much like Attinger does to transformers, yet neither seem to hate each other specifically) to kill the remaining Autobots including Ratchet, Leadfoot, (possibly Sideswipe and Mirage) and Deceptions on Earth while offering the Seed in exchange for aid in hunting Optimus. At some point in the past, Lockdown also captures the Legendary "Dinobot" Knights and took over the Knight Ship, but they are later freed by Optimus in order to destroy Galvatron's army. Later in a duel at Hong Kong, Lockdown is bisected by Optimus Prime, avenging the deaths of Lucas, Ratchet, and Leadfoot. Afterwards, his body was disposed of by his own grenade, when Optimus destroys the rest of the KSI Drones.
  • The Shadow Raiders 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. It is revealed in The Last Knight that they were knocked out by Daytrader, taking the Knight Ship for the Autobots.
  • The Steeljaws are the techno-organic wolf-like creatures and the minions of Lockdown. They are colored black and blue in the toyline. During the Autobots' raid in the Knight Ship while hanging on the cables, they are killed by Cade Yeager and Bumblebee.
