The heroes of the saga. A group of civilians, scientists, and soldiers founded by Optimus Prime to defend the AllSpark from Megatron. The war eventually deteriorated Cybertron, forcing the Autobots to launch the AllSpark to prevent it from falling into Decepticon hands. Millions of years later, the AllSpark was rediscovered on Earth, re-starting the Autobot–Decepticon conflict. Later films show the Autobots forming an alliance with humanity to defend Earth from the Decepticons, as the loss of the AllSpark has eliminated any possibility of rebuilding Cybertron.


In General:

Advertisement:
  • Alien Among Us: The benevolent kind.
  • Arm Cannon: Most Autobots have them, until they began to get phased out in Dark of the Moon.
  • Badass Crew: Whether it's Optimus's initial Five-Man Band or the Ragtag Bunch of Misfits plus the Dinobots, they're a force to be reckoned with.
  • Band of Brothers: In the first three films. The fourth features a bunch of loners and misfits who don't get along, eventually becoming Fire-Forged Friends.
  • Beauty = Goodness: The Autobots have human-like appearances so that audiences can identify as them as the good guys. Their faces resemble human faces and they have five-fingered hands. Even Jetfire and Drift, defectors from the Decepticons, can be identified as good guys by this trope. Sentinel Prime subverts it.
  • Car Fu: These Autobots certainly have a lot more creativity with their vehicle forms, especially with Optimus being as big as he is.
  • Advertisement:
  • Dark Is Not Evil: A number of them (i.e., Ironhide and Hot Rod), sport dark colors, but they are heroes.
  • Dual Wielding: Be it blades or guns, every Autobot does this with every Shapeshifter Weapon they have.
  • Dwindling Party: The original five Autobots from the first film (Optimus, Bumblebee, Ironhide, Ratchet and Jazz). The films consistently kept the tendency to kill one per movie Jazz dies in the first, Optimus dies in the second, Ironhide in the third and Ratchet in the fourth. Out of them, only Optimus came back, leaving Optimus and Bumblebee as the last remaining members of the original group.
  • Hero with Bad Publicity: Despite saving the world in every film, the people of Earth are unfriendly and want them off Earth; the third film had them exiled and the fourth film had them the victims of a manhunt. Somewhat justified as humanity can't cope with an alien war on Earth and takes the easier choice of getting rid of them, which always proves wrong so they eventually stand with the Autobots.
  • Advertisement:
  • Innocent Blue Eyes: Most Autobots have blue eyes, like in Generation One, so that they can be identified as the heroes. Exceptions are Jetfire, Sentinel Prime, Drift, and the Dinobots.
  • Mechanical Lifeforms: As is tradition.
  • Mildly Military: They don't show any sort of military discipline whatsoever, even if they work alongside the human military. Hound comes off as a grizzled, over-the-hill veteran brought back out of retirement.
  • La Résistance:
    • The Decepticons clearly outnumber the Autobots, both in terms of the on-screen cast and in the universe at large, leaving Optimus's unit as seemingly the sole force really putting a dent in the Decepticons.
    • Taken even further in Age of Extinction, with the Autobot-human alliance being dissolved and the Autobots being forced to go on the run.
  • Shapeshifter Weapon: Their arms transform into their weapons. Dark of the Moon and Age of Extinction subvert it, with the Autobots' weapons being handheld instead.
  • Transforming Mecha: Natch.
  • True Companions: The cast of the first three films act as a well-oiled bunch of killing machines, fueled by their long comradeship and friendships. Averted initially in Age of Extinction: the only Autobots that survived The Purge are a bunch of loners, misfits, and assholes who clearly don't belong together, but they're stuck with each other because they're literally all that's left. By the end of the film, however, it's safe to say they've become this.

Introduced in Transformers (2007)

    Optimus Prime

"Sam, fate rarely calls upon us at a moment of our choosing."

Voiced by: Peter Cullen, Blas Garcia (Latin-American Spanish dub, 2007-2011), Alfonso Ramirez (Latin-American Spanish dub, 2014) Tessho Genda (Japanese dub)

The valiant, courageous and noble leader of the Autobots, Optimus is very guilt-ridden about the damage done to Cybertron and protects the Earth so that it doesn't suffer the same fate. Though idealistic, millions of years of war have hardened him considerably, and he is willing to take more brutal methods than usual to end the war. He transforms into a series of semi trucks, most prominently a Peterbilt 379.


  • Action Hero: He's a soldier, after all. He sees more action than any other Autobot in the films.
  • An Axe to Grind: Used in DOTM to devastating effect, and in the end to kill Megatron.
  • Antiquated Linguistics: Rarely uses contractions.
  • Arm Cannon: Gains one in RotF using Jetfire's parts.
  • Asskicking Equals Authority: How Optimus gains the loyalty and support of the Dinobots.
  • Authority Equals Asskicking: There is a reason why some of the best fight scenes have him in them.
  • Back from the Dead: What? It's nothing new.
  • Badass Baritone: Well, he is voiced by Peter Cullen.
  • Badass Boast:
    • "I'll take you all on!"
    • To a lesser extent, "We're NOT your technology!!" note 
  • Badass in Distress: He is captured by Lockdown and brought to his prison ship in Age of Extinction. The other Autobots free him, along with the captured Dinobots.
  • Being Good Sucks: Boy, does it ever! So many tragedies happen to Optimus in the film series, even when most of them aren't really his fault. He could leave Earth to its fate—he was even considering it in Age of Extinction—but he chooses to stay because of his belief in the freedom all sentient beings deserve.
  • Benevolent Boss: An effective commander and a loyal friend to his subordinates.
  • Bequeathed Power: Optimus achieves his upgraded form when Jetfire donates his parts to him.
  • Berserk Button:
    • Don't you dare harm any human in front of him, especially humans who are particularly close to him. He WILL scare the crap out of you, like what he did to Sector Seven, who kidnapped Sam and Mikaela. Or beat you senseless, like what he did to Megatron, Starscream and Grindor when they captured Sam and tried to get his brain. He destroys the Fallen, who was endangering the whole human race, and brutally cleaves Megatron's head in half and then uses the latter's gun to blow Sentinel Prime's head off for slaughtering thousands of people and several of his friends.
    • Changed in Age of Extinction. With humanity indiscriminately killing Autobots, Ratchet being the most recent casualty, it takes all of his self control to stop him from killing every human in sight. To his credit, he doesn't go destroying city blocks like the Decepticons, and directs his rage at those who are responsible for or are accomplices to the betrayal. Furthermore, attempting to harm the Yeagers in his vicinity pretty much ends badly for anyone who tries it, particularly Attinger and Lockdown.
  • Beware the Nice Ones: The greatest living Cybertronian warrior is according to Word of God a peace loving and kind-hearted scientist, so don't piss him off or he'll take your face.
  • Big Badass Rig: He transforms into a long-nosed Peterbilt 379 truck in the first trilogy; in Age of Extinction, he transforms into a rusty Marmon 97 semi truck and later into a Western Star 4900 Phantom Custom semi-trailer truck.
  • Big Damn Heroes: His job in a nutshell.
  • Big Good: Leader of the Autobots and all that. Age of Extinction shows that without him, the Autobots were getting ready to blow each other apart. Also, when Optimus gains the loyalty of the Dinobots, this exchange happens.
    Crosshairs: Ugh, you just want to die for the guy. That's leadership... or brainwashing... or something.
    Drift: No, that's Optimus Prime!
  • Black and White Insanity: In the fourth film. While he's justified in being angry at the humans involved with the killing of his friends and using them for experiments, he seemingly extends that anger to all humans, excepting only those who help him (Cade and his family), as if they're all bad. Thankfully changed at the end, though.
  • Blade Below the Shoulder: One in each arm. He switches to using more conventional handheld swords from Dark of the Moon onwards.
  • Brainwashed and Crazy: In TLK, by Quinessa, to aid her. It lasts until he nearly kills Bumblebee.
  • Broken Pedestal: He starts out advocating for humans and holds them in high regard, despite various Autobot and Decepticon characters explicitly telling him that humans are a warlike and unintelligent species which don't deserve his protection. The pedestal cracks significantly when Sentinel Prime, his mentor and the one who instilled these principles into Optimus, betrays him and the Autobots in the third film. Thanks to the humans turning on them soon after, this pedestal is thoroughly broken by the fourth movie, if his initial reaction upon being reawakened is any indication. Once he learns of Ratchet's fate, you might as well pull out a fusion cannon and vaporize any remnants of said pedestal.
  • But Now I Must Go: At the end of Age of Extinction, Optimus takes the Seed and heads into deep space alone, leaving the remaining Autobots on Earth, as he still has to confront his apparent Creators.
  • Character Development:
    • By the end of the first trilogy, he has finally lost all hope for peace with Megatron, especially after the massacre of Chicago.
    • The fourth film focuses on him regaining faith in humanity after a quite unforgivable betrayal.
  • Composite Character: In most continuities, Nemesis Prime is his Evil Doppel Ganger. Here he is given the name after he is brainwashed.
  • Cool Mask: He has a retractable faceplate for combat situations. Megatron breaks it in Revenge of the Fallen, but it gets repaired when Optimus merges with Jetfire's parts.
  • Cool Sword: He wields a longsword in Age of Extinction.
  • Combat Pragmatist: Very much so. Starting from his first fight scene, where he rams his blade into Bonecrusher's face. There is practically nothing he won't use as a weapon against a foe.
  • Et Tu, Brute?: His very realization when he discovers that Sentinel Prime had betrayed him and the Autobots.
  • Fatal Flaw: Idealism. At first, Optimus believes in the unfailing goodness of all living things, both human and Cybertronian, and ignores the advice of his more pragmatic friends. While it's implied his idealism is fueled by his desire to end centuries of warfare, it does him no favors while confronted by the betrayals of Megatron, Sentinel and even the humans he swore to protect. Over the course of the series, Optimus learns to let go of his idealism' more negative aspects and keep his sense of perspective.
  • Genius Bruiser: Aside from being a formidable soldier, he's also one of Cybertron's greatest scientists.
  • Gentle Giant: Being the largest Autobot in the main group, he fits this trope the most.
  • Good Is Not Soft: As several very dead Decepticons can attest, Optimus is merciless in a fight.
  • Guns Akimbo: He wields two guns when attacking Megatron to save Sam in Revenge of the Fallen.
  • The Hero: He is the alpha protagonist over the course of the movies. Sam and Cade might provide a human perspective the story, but Optimus is the one moving the story forward.
  • Heroes Prefer Swords: Optimus gets to use swords quite a lot through the saga, such as his arm-blades in the first trilogy and the longsword in Age of Extinction.
  • Heroic Sacrifice: He gets better, though.
  • Heroic Spirit: He wouldn't be Optimus Prime if he didn't display it.
  • Honor Before Reason: Except when he kills Megatron at the end of DOTM instead of accepting a "truce". Though considering Megatron seemed less than sincere, taunted Optimus while asking for said truce, and still had his gun pointing at him, this is a Justified Trope. The novel has him use this trope all the way through, though in both the novel and comic adaptations, Megatron is clearly sincere about the truce, and even asks Optimus to kill him if he deems it fit.
    • Then again, Optimus calls out Sentinel on making an alliance with Megatron, so if he did the same, he would look like a Hypocrite.
  • Hooks and Crooks: A memorable scene in Revenge of the Fallen has him swapping his blades for hooks, then using said hooks to tear Grindor's head apart.
  • Hot Blade: His swords are superheated, allowing Optimus to slice his enemies more easily.
  • Hot Paint Job: Optimus has red flames painted on his blue chassis, letting him keep the iconic red-chest-windows look.
  • Humans Are Special: Firmly believes this, and trusts his human friends with his life.
  • Humans Are the Real Monsters: Tragically, has come to believe this by the time of the fourth film, after The Purge that wiped out most of the Autobots on Earth, luckily Cade convinces him otherwise.
  • Hurting Hero: Just like in Generation 1, there is an ever present yet dignified sadness in Peter Cullen's performance of Optimus, as if The Great War has affected him so deeply, that he is always crying deep inside. Cullen stated in interviews that he drew inspiration from his brother Larry, a Shell-Shocked Veteran of The Vietnam War, who told him before the audition for Optimus "Don't be a tough hero; you are strong enough to be gentle." This is given far more focus in Age of Extinction.
  • Ideal Hero: Deconstructed and reconstructed in Age of Extinction. Optimus's faith in humanity results in them slaughtering Autobots to create their own Transformers. Optimus is angry at this betrayal and is ready to abandon them to their fate, but Cade re-awakens Optimus's idealism and convinces him humanity is still worth protecting.
  • I Did What I Had to Do:
    • This is what he says to Megatron's corpse at the end of the first film, and it clearly pains every inch of his being.
    • Not quite so much the second time 'round, though. Killing The Fallen, Sentinel Prime, Lockdown and Attinger similarly leaves him with little remorse.
  • Jet Pack: Gains one from Jetfire's parts in Revenge of the Fallen, his trailer can become one in Dark of the Moon, and has booster rockets on his legs in Age of Extinction.
  • Knight In Sour Armor: Has become this by Age of Extinction. He ultimately gets better, but it's clear the past couple years of hiding and fighting for his life have taken a toll on him. For one thing, he legitimately considers leaving humanity to face the apocalypse they brought on themselves.
  • Large and in Charge: The tallest of the Autobots at 32 ft., until Jetfire (50 ft.) gets involved, and then later the Dinobots.
  • Large Ham: Downplayed. He has his moments here and there, though.
  • Last of His Kind: Was believed to be the last of the Primes, and was therefore hunted by the Fallen (who lost his title when he betrayed his brothers). Dark of the Moon reveals that he actually isn't; Sentinel Prime is still around, and when Optimus finds out, he revives the old warrior. Then Optimus kills Sentinel after the latter tries to enslave humanity, putting this trope back into effect. Ouch.
  • The Leader: A combination of the Levelheaded and Charismatic varieties. Optimus remains calm and taciturn in combat situations and is able to inspire his soldiers through his charisma and idealism.
  • Lightning Bruiser: He's the tallest of the Autobots and is capable of pulling off impressive acrobatic stunts. Dark of the Moon shows his strength and speed in a Foe-Tossing Charge that ends up killing Shockwave.
  • Like a Son to Me: Implies Bumblebee is this in Age of Extinction.
  • Living MacGuffin: In Age of Extinction, Lockdown wants to capture Optimus and bring him to his Creators.
  • Luckily, My Shield Will Protect Me: He carries a shield to match his Hot Blade in Dark of the Moon and his longsword in Age of Extinction.
  • Master Swordsman: Whenever he gets his hands on a sword, Optimus becomes more lethal than usual.
  • Messianic Archetype: It's Optimus Prime, this is par for the course.
  • Midseason Upgrade: Every new movie sees Optimus getting a new upgrade like there's no tomorrow. First, his combination with Jetfire's parts in Revenge of the Fallen, then his trailer in Dark of the Moon contains a whole arsenal for him to use, and in Age of Extinction, scanning a new alt-mode redesigns his body with new weapons.
  • My God, What Have I Done?:
    • After Sentinel Prime goes on a rampage, killing Ironhide and destroy the NEST base, the look on his face as he realizes this is his fault for bringing Sentinel back can only be described as this.
    • Says this word for word after snapping out of his brainwashing and realizing that he nearly killed his friends
  • Narrator: Every movie begins and ends with a narration from Optimus.
  • Nice Guy: Optimus is loyal, friendly, noble and treats both Autobots and humans with kindness and respect.
  • Off with His Head!: His fondness for this spawned the meme. note 
  • Old Friend: He's closest to Bumblebee, Ratchet, and Ironhide. He does not take the deaths of the latter two well at all.
  • Papa Wolf:
    • He loves his human friends like his own children, and would literally tear you a new one if you harm even one of them; Starscream, Grindor, The Fallen, and Megatron find this out the hard way.
      Optimus: Taking the children was a bad move.
    • And then in DOTM when Sentinel Prime, his father figure and teacher, has led an invasion of Chicago that murdered and enslaved millions of innocent civilians, Optimus shoots the bastard execution-style as he begs helplessly for his worthless life lying on the ground. Do not screw with a race that Optimus Prime has come to love.
  • Primary-Color Champion: Naturally, by way of his Hot Paint Job.
  • Protagonist Powerup Privileges: Optimus is among the very few characters to get a power-up in each movie.
  • Rage Against the Mentor: Towards Sentinel Prime.
  • Rated M for Manly: A giant robot that transforms into a Big Badass Rig with a Hot Paint Job, has a deep voice and uses swords in battle.
  • Reasonable Authority Figure: He is always willing to let his friends handle things if the situation calls for it.
  • Restored My Faithin Humanity: Cade's words about having faith in what humanity can be instead of what they are, along with him and his family risking their lives to save him and help him fight Lockdown cause this
  • Roaring Rampage of Revenge: Optimus leads a truly terrifying one when he learns that Ratchet was slaughtered and is being melted down for parts.
    Optimus: THEY SLAUGHTERED RATCHET!!! I'M GONNA TEAR THEM APART!!
  • Self-Made Orphan: Kills Sentinel Prime, his father figure.
  • Series Mascot: Shares this role with Bumblebee.
  • Shotguns Are Just Better: He uses Megatron's shotgun to execute Sentinel Prime in Dark of the Moon.
  • Standardized Leader: Comes with being Optimus Prime. He doesn't have the quirks of other Autobots, is more focused on the mission and rarely affords moments of leisure.
  • Supporting Leader: In the first film, Optimus stands in the background while Sam is in the spotlight. Subverted in the sequels.
  • There Is No Kill Like Overkill: Blasting Attinger with a weapon designed for giant mechanical lifeforms. Not that many were sad about it.
  • Took a Level in Badass: In the first film, Optimus took out Bonecrusher, but could barely stand against Megatron. In the second, likely to add more emphasis on the importance of Optimus being a Prime, Optimus suddenly becomes strong enough to competently AWESOMELY battle Megatron, Starscream and Grindor at the same time! Taken Up to Eleven in the third film where he leads a massive Foe-Tossing Charge and kills Shockwave on one combo.
  • Took a Level in Cynic: By Age of Extinction, years of the Autobots being hunted down by humans has caused Optimus to lose much of his faith in them, to the point where he will not hesitate to kill humans in self-defense. He regains his idealism and faith in humanity at the end though.
  • Walking Armory: Two ion blasters, two retractable Hot Blades, two superheated hooks, an axe (also superheated); the trailer he gets in the third film adds a shield, a BFG, spiked knuckles, and a jetpack; and he gets the "Sword of Judgement", another shield, and rocket boosters in his feet from Lockdown's ship. The guy's positively armed to the teeth.
  • Weaponized Exhaust: His upgraded form in Revenge of the Fallen can throw Megatron through a stone wall.
  • Wolverine Publicity: Optimus gets the spotlight of any movie's marketing campaign, alongside Bumblebee and the human protagonists,
  • Wrecked Weapon: At least one of Prime's swords is broken when fighting Galvatron in Age of Extinction.
  • You Are Not Ready:
    • Refuses to share Autobot weapons advances with the humans for fear of them pointing said weapons at non-Decepticon targets. Part of this is because he's afraid of contributing to mankind destroying themselves like his own race did. In other words, if the Cybertronians weren't responsible enough not to wipe out their own race with their weapons, how is a race who are millions of years behind them supposed to?
    • Age of Extinction proves just how justified Optimus was with this, since what little they did share with the humans is indeed used against them. The scene of Ratchet's death is eerily similar to the opening sequence of ROTF, only turned on the poor Autobot medic.

    Bumblebee 
https://static.tvtropes.org/pmwiki/pub/images/300px-tf-alliance03_cover_nizzi_7455.jpg
Voiced by: Mark Ryan (Transformers), Erik Aadahl (Transformers: The Last Knight), Alfredo Gabriel Basurto (Latin-American Spanish dub, 2007-2011), Akio Kato (Japanese dub/Transformers, non-radio voice), Hiroshi Iwasaki (Japanese dub/Transformers, radio voice), Kōichi Yamadera (Japanese dub/Transformers: Age of Extinction), Masato Obara (Japanese dub/Transformers: The Last Knight), Ryohei Kimura (Japanese dub/Bumblebee)

Sam's designated guardian, Bumblebee is a 16-foot tall yellow Autobot. His vocal processor was damaged, so he speaks through the radio in his Chevrolet Camaro form.


  • Adaptational Badass: An example that made its way into later series featuring the character. In Generation One, Bumblebee's main purpose was evacuating humans from danger while the larger Autobots did the fighting. In the movies, Bumblebee is active in combat.
  • Animal Motifs: With bees and even dogs.
  • Beware the Nice Ones: He's one of the friendliest Transformers in the series, even compared to other Autobots, but he's also an extremely skilled fighter with a fair number of Decepticon kills to his name, and you do not want to piss him off. Burns and his men learned that last part the hard way.
  • Character Development: He goes from scout to guardian to warrior over the course of the series.
  • Combat Parkour: Due to his light armor and small size, Bumblebee cannot defeat enemies through brawn alone, so he has to leap around the battlefield to keep his enemies distracted.
  • Composite Character: Has the name and color scheme of his Generation One self but his design takes cues from Prowl and Bluestreak. He even provides the page image.
  • Deadpan Snarker: He can't talk, but he gets his points across.
  • Demoted to Extra: Downplayed in Age of Extinction. While Bumblebee is still a relevant character, his role as the designated guardian to the human protagonists is taken by Optimus. He seems to develop a small bond with Shane, however.
  • Detachment Combat: He's somehow picked up the ability to do this in The Last Knight.
  • Drop the Hammer: He uses a warhammer in The Last Knight against Nazis in a flashback sequence and Nemesis Prime in the present.
  • Handicapped Badass: His inability to speak does not reduce his ability in combat one bit.
  • Heroic Mime: Not by choice in the first movie: backstory reveals that a battle that takes place before the films ended with Megatron ripping his arms off and then crushing his vocal processors. In the second movie, Sam says that he plays it up.
  • Kid-Appeal Character: Though he's much more badass this time around.
  • Kid Hero: Bumblebee's exact age is unknown, but given the audio clips he uses to communicate, he displays the behavior of a teenager at the very least.
  • Nice Guy: He is one of the easiest Autobots to get along with. Optimus and Sam are very fond of him for this reason.
  • Pint-Sized Powerhouse: Compared to other Autobots, at least.
  • Poor Communication Kills: His failed attempts to inform Sam that the hot girl Alice who's riding with them is a Decepticon.
  • Puppy-Dog Eyes: He's very emotional.
  • Series Mascot: Shares this role with Optimus.
  • Shipper on Deck: In the first two movies, it's quite apparent that he's all for Sam & Mikaela. In the first he's outright trying to play The Matchmaker. We don't know his thoughts on "Sam and Mikaela's break up", but whatever the case, he, like Sam, has clearly moved on, and totally jumped on the Sam/Carly boat, outright trying to hint that he wants Sam to propose to Carly at the end of the third film.
  • True Companions: Considers Sam this, at one point "saying" that Sam is "the person I care about most in my life. If there's anything you ever need, I won't be far away."
  • Weak, but Skilled: Bumblebee's one of the smaller Autobots, so strength isn't one of his strong suits. However, he's also one of the smarter fighters, knowing how to use the environment to his advantage and exploit bigger opponents' weak spots to level the playing field.
  • Wolverine Publicity: He is always at the forefront in advertisements, alongside Optimus and the human protagonists.

    Ironhide 
https://static.tvtropes.org/pmwiki/pub/images/img_0037.JPG
"I'm a soldier. I'm made for war. Your kind simply... are not."
Voiced by: Jess Harnell, Dafnis Fernández (Latin-American Spanish dub, 2007-2011), Katsuhiro Kitagawa (Japanese dub)

A grouchy war veteran and Optimus's oldest friend. Ironhide is a proud figure who enjoys fighting and likes showing off his arm cannons. He transforms into a black GMC Topkick pickup truck. He is the first Autobot fatality of the third film, killed by the opening betrayal shot of the treacherous Sentinel Prime.


  • Arm Cannons: One in each arm.
  • Badass Baritone: His voice is very deep.
  • Bash Brothers: Mostly in the first movie, with Ratchet.
  • Blood Knight: Though thankfully much nicer than Sideswipe.
  • The Big Guy: He is the Autobots' weapons specialist.
  • Character Development: In the first film, he was pretty cantankerous and disapproved of the Autobots' aiding humanity. By ROTF, he's happy to work with them, and even accepts orders from them. Plus, he's become cool-headed enough to be a worthy second in command of the Autobots.
  • Demoted to Extra: Despite not getting this as bad as Ratchet, he's a very minor character in Revenge of the Fallen, though he does get a good fight scene in DOTM.
  • Et Tu, Brute?: His very reaction when he was shot In the Back by Sentinel Prime.
  • Famous Last Words: "What have you done...?"
  • Foreshadowing: Worries about rusting when Sam's dog pees on him in the first movie. This is exactly how he dies two movies later, courtesy of Sentinel Prime.
  • Hypocrite: He complains that humans are a violent race, all the meanwhile gloating to Sam about his cannons.
  • In the Back: How Sentinel Prime murders him.
  • Jerk with a Heart of Gold: He doesn't like humans too much, but he'll fight for them all the same.
  • Killed Off for Real: By Sentinel Prime.
  • Number Two: After Jazz's death, he takes on the role of the Autobots' second-in-command, leading in the field when Optimus isn't around. Upon Optimus' death in Revenge of the Fallen, he seems to take over the Autobots, though he's willing to defer to Lennox when he doesn't know something about Earth (like the terrain in Egypt).
  • Old Soldier: He is old by Cybertronian standards and is still one of the best Autobots in the field.
  • Proud Warrior Race Guy: In the comics, it's noted he was initially part of the Thetacons, who were separate of the Autobots and Decepticons. Although not technically a different race, he does say "I was built for war. Your kind, simply, are not."
  • Sacrificial Lion: Sentinel Prime's coldblooded murder of Ironhide shows just how dangerously unstable the old guy has become.
  • Sociopathic Hero: His Trigger Happy nature could easily associate him as such. He eventually grows out of it, though.
  • Trigger Happy: Replying to Optimus scolding him for half-jokingly suggesting they slag Sam's annoying parents: "I'm just sayin' we could. It's an option..." The first movie's Video Game also implies that he's responsible for destroying an entire planet. Though Ironhide claims that "it was gonna blow up anyway."
  • Unnecessary Combat Roll: Seems very fond of this, especially in the first movie.

    Ratchet 
https://static.tvtropes.org/pmwiki/pub/images/img_0039.JPG
Voiced by: Robert Foxworth, Jesús Cortez (Latin-American Spanish dub, 2007-2011), Jin Urayama (Japanese dub)

The Autobot's medical and science officer. A former member of Cybertron's High Council, Ratchet is very diplomatic and intelligent. He transforms into a Hummer Search & Rescue truck.


  • An Arm and a Leg: Ratchet gets his left leg blown off by Cemetary Wind as they pursue him. He tries to use this to get them to take him alive. It doesn't work when he learns they have no intention of wanting him alive.
  • Arm Cannon: His right arm turns into a machine gun.
  • Badass Bookworm: He's one of the smartest Autobots and he's no slouch in combat either. He is always taking part in the battles across the series, and has taken on the likes of Brawl, Megatron and Starscream, and Sentinel Prime. He was one of the last casualties of Cemetery Wind's hunt, managing to hide and survive for five years on his own.
  • Bash Brothers: Mostly in the first movie, he's this with Ironhide.
  • Combat Medic/Deadly Doctor: His weapons are often also medical tools, and he constantly makes use of his knowledge in combat.
  • Cruel and Unusual Death: He's hunted down by Cemetery Wind and brutally worn down and blown apart by their superior firepower. Then, Lockdown arrives (after having sniped him), rips into his chest, and removes his spark.
  • Defiant to the End: When he realizes he isn't going to be spared, he puts up as much of a fight as he can before his death, and spits in Lockdown's face when offered a chance to survive by ratting out Optimus.
  • Demoted to Extra: A major character in the first movie, but unlike Bumblebee or Ironhide, his screentime decreased massively by the second. The third film does try to give him more spotlight, however. And the fourth film brings him back only to be Killed Off for Real, in a particularly brutal fashion.
  • Face Death with Dignity: Though he initially panics while being hunted down, he sadly accepts his death and lies back and waits for it.
  • Famous Last Words: "Never."
  • Foil: To Ironhide.
  • Friendly Sniper: If one pays attention to his fighting style, he mostly walks slowly while carefully aiming and sharpshooting his foes with precision.
  • Gentleman Snarker: Upon being confronted by Galloway, his reaction is "This fool is terribly misinformed."
  • The Heart: Besides Bumblebee and Que, he is the most genuinely nice member of the Autobots and is good friends with the entire team. His death in Age of Extinction sends Optimus and the surviving Autobots into a rage, even those who we never saw interacting with him, like Cade, Hound, Crosshairs and Drift.
  • Ink-Suit Actor: His appearance seems to be styled after Mr. Foxworth himself.
  • Killed Off for Real: Wounded by Cemetery Wind operatives while responding to Optimus's call to arms, leaving Lockdown to finish him off in Age of Extinction.
  • My Sensors Indicate You Want to Tap That: See his quote.
  • Nice Guy: In contrast to most Ratchets from alternate continuities, who are, at the very least, a Dr. Jerk / Jerk with a Heart of Gold.
  • Noble Profession: Being a doctor and all.
  • Officer and a Gentleman: Alongside Optimus, the most polite of the Autobots. Overlaps with Gentleman and a Scholar.
  • Omnidisciplinary Scientist: Seems to know everything from chemistry, physics, biology, and medicine.
  • Old Friends: With Optimus, Ironhide and Bumblebee. It's his death and subsequent desecration that sends Optimus over the edge in Age of Extinction.
  • Sacrificial Lion: In Age of Extinction. He gets an entire scene depicting his slow, brutal death at the hands of Cemetery Wind and Lockdown, to not only show what's been happening to the Autobots since Dark of the Moon, but what will happen to Optimus and company if they're found.

"You wanna piece of me?! You wanna piece?!"
Voiced by: Darius McCrary, Gerardo García (Latin-American Spanish dub, 2007-2011), Taiten Kusunoki (Japanese dub)

"This looks like a cool place to kick it!"

Optimus's first lieutenant. He loves Earth's cultures and styles and has since taken on several of Earth's customs. He transforms into a Pontiac Solstice hardtop convertible.


Introduced in Transformers: Revenge of the Fallen (2009)

    Sideswipe 
https://static.tvtropes.org/pmwiki/pub/images/300px-revenge_of_the_fallen_sideswipe1_6826.jpg
Voiced by: André Sogliuzzo (ROTF), James Remar (DOTM)

Introduced in the second film. Sideswipe is a silver-armoured Autobot with retractable blades on his arms and wheels for feet. He is a bit of a showoff. In the tie-in comics, Sideswipe was in charge of an Autobot colony until it was destroyed by Demolishor and chased him to Earth where he joined Optimus's team. He transforms into a Corvette Stingray car. DOTM sees a slight change to a convertible variant.


  • Backpack Cannon: Which he likes to fire downward at foes while flipping over them.
  • Blade Below the Shoulder: One in each arm.
  • Blood Knight: According to the Tales of the Fallen tie-in comic: "I am a warrior; I bleed conflict."
  • Cool Car: A shiny new Corvette.
  • The Lancer: After Ironhide's death, Sideswipe is seen leading the Autobots in the battle for Chicago when Optimus isn't around.
  • Killed Off for Real: Tie-in cards for Age of Extinction confirm he was hunted down and killed by Cemetery Wind and Lockdown during the Time Skip between the third and fouth films.
  • Killed Offscreen: His death was never shown.
  • Sociopathic Hero: Tie-in comics establish him as not caring about civilian casualties. He mellows out a bit by the time he appears in the movie, though.
  • Rollerblade Good: Two of his Corvette's tires form his feet; he uses skating moves to get around.
  • Shout-Out/Continuity Nod: Sideswipe's backstory appears to be inspired by that of Depth Charge from Beast Wars, who guarded a Maximal colony until it was destroyed by Rampage.

    Jetfire 
https://static.tvtropes.org/pmwiki/pub/images/img_0383.JPG

Voiced by: Mark Ryan

"Behold, the eternal glory of Jetfire!"

An elderly Decepticon turned Autobot. He was once a Seeker Transformer, but was abandoned on Earth by the Fallen and joined the Autobots as a result. He is falling to pieces but is resourceful and actually a pretty awesome fighter. He transforms into an SR-71 Blackbird jet.


  • The Atoner: As an ex-Decepticon, he gets a chance of redemption by aiding the Autobots.
  • An Axe to Grind: His landing-gear cane conceals an axe blade.
  • Badass Beard: Yes, robots can have beards, why do you ask?
  • Been There, Shaped History: According to the tie-in comics, he accidentally provoked the Spanish-American War.
  • Bifurcated Weapon: His cane/axe.
  • Character Blog: He has a formspring account.
  • Cool Old Guy/Grumpy Old Man: He straddles the line between these two tropes. One hand, Jetfire is easy to anger and not very happy to learn the Decepticons are winning the war. On the other hand, he is very skilled in combat, happy to see Optimus return to life and willing to take his own life to give Optimus an upgrade.
  • Composite Character: He is based on his G1 version (a plane Transformer who is a Decepticon-turned Autobot), and shares traits of Kup (an elderly Autobot) and Sky-Lynx (a bombastic jet). His parts form a jetpack for Optimus Prime, a homage to Jetfire in the Armada cartoon
  • Cool Plane: His altmode is an SR-71 Blackbird, which for the uninformed holds the still-unbeaten record for fastest military aircraft.
  • Deadly Upgrade: Unusual in that it's not for him. He dies to upgrade Optimus.
  • Heel–Face Turn: Technically he made it decades—if not centuries—before the movies take place, but never got around to changing his altmode's emblem, leading to a slight panic situation with Sam & co. at first.
  • Heroic Suicide: So that Optimus can get a much needed upgrade.
  • Large Ham
    • Incoming Ham: "BEHOLD! The eternal glory of... Jetfire!!!" (and of course, his first line: "What sort of hideous mausoleum is this?!")
  • Madeof Iron: He's pretty tough, even by Transformer standards. He survives being dismembered by Scorponok and later on a massive airstrike that obliterated the Decepticon army. He dies only when he gives up his life and parts to help Optimus Prime. He died by his own hand, as no one could kill him.
  • Mr. Exposition: Explains what the heck the Fallen's beef with humanity is.
  • Old Soldier: One of the oldest Cybertronians we've seen, and when he actually fights he shows how good he is.
  • Precision F-Strike: "Oh, BOLLOCKS!"
  • Sanity Slippage: In Wheelie's words, he has not aged well.
  • Screw Politeness, I'm a Senior!

    Arcee, Chromia, & Elita- 1 
https://static.tvtropes.org/pmwiki/pub/images/250px-rotfconceptarceecombinerdvd3_3486.jpg
"We're on our way."

Voiced by: Grey DeLisle
Hologram rider played by: Erin Naas

A trio of female Autobots who transform into motorcycles. Arcee was captured by the Decepticons Thundercracker and scientist Flatline, who created Chromia and Elita-1, planning to use the three as attack drones, but they combined their mental links and escaped to Earth.


  • Action Girl: They're soldiers, this is a given.
  • The Bus Came Back: Grey Griffin returned to give Arcee a one-liner in Bumblebee.
  • Chuck Cunningham Syndrome: While they don't return for DOTM or AOE, the comics overrode their apparent death in ROTF, showing them alive and well post-Fallen, although Elita-1 was killed by Shockwave. Arcee and Chromia survive, making their current status alive, just off screen with all the other comic Autobots that weren't killed by Shockwave but didn't appear in DOTM. Arcee is listed as deceased by Cemetary Wind in Age of Extinction though.
  • Combining Mecha: Not in the movie itself, mind, but they originally would have. They still do combine in the comics and (supposedly in the toyline.)

    Skids & Mudflap 
Voiced by: Tom Kenny (Skids) and Reno Wilson (Mudflap)

Skids: You scared?
Mudflap: Scared? Scared of your ugly face!
Skids: I'm ugly? We're twins, you stupid genius!

A pair of kid-like Autobots who are identical twins save for their colors (green and red). They begin Revenge of the Fallen as combiners, transforming into two halves of a beat-up ice cream truck, and later take on Chevrolet subcompact forms.


  • Sibling Yin-Yang: Skids thinks he's the smart one, but to everyone else they're both obviously kinda stupid. Skids is also inwardly fearful that he's ultimately the weaker of the two, which frankly he sort of is. However, they both process information much more rapidly than any of the other Earthbound Autobots, so that's something.

    Jolt 
"Jolt, electrify! Transfer those afterburners!"
Ratchet

A blue-armored Autobot who becomes a Chevrolet Volt. He is shown to be an assistant to Ratchet, wielding a pair of electrical whips. He is killed by Shockwave during the events between the second and third films.


  • The Cameo: Well, sort of. His head can be briefly seen on the Junkyard in The Last Knight.
  • Killed Off for Real: According to the IDW tie-in comics, Jolt was at Diego Garcia when Shockwave came calling, killing Jolt as well as the other two Autobots present.
  • Real Life Writes the Plot: Jolt is such a minor character because he was an extremely late addition to the film, which didn't exactly make it easy for the film crew to give him a role.
  • Satellite Character: He doesn't have a single line throughout the entire movie, and has no apparent importance besides helping upgrade Optimus at the end. And he doesn't appear in any of the subsequent movies, either.
  • Shock and Awe: Wields a pair of electrical whips, befitting his alt-mode (a primarily battery-powered car).
  • The Voiceless: He never says a single word in the entire film.

    Wheelie 
https://static.tvtropes.org/pmwiki/pub/images/300px_rotfwheelie.jpg

Voiced by: Tom Kenny

"Easy, Warrior Goddess, I'm just a little salvage-scrap drone!"

A small salvage scrap drone used by the Decepticons as a spy, he transforms into an RC toy truck. He is sent to retrieve the Allspark shard given to Mikaela by Sam, but ends up siding with the Autobots.


  • Chuck Cunningham Syndrome: Though Brains has a significant role, Wheelie doesn't appear in Age of Extinction. It's conceivable that he's wherever Sam and Carly are if he survived the climax of Dark of the Moon, or given what happen to his buddy Brains, a victim of The Purge. He turns up in ''The Last Knight'', living with the other Autobots in Jimmy's junkyard.
  • Dying Moment of Awesome: He and Brains take control of a Decepticon carrier, providing a distraction at a crucial moment. When last seen, they appear to be on a crash course into Lake Michigan. Subverted, as Brains survives and Wheelie both survive.
  • Eye Scream: His first meeting with Mikaela involves her pinning him down and taking a blowtorch to his optic.
  • Famous Last Words: "We had a nice run, Brains, you and me." Though in the fifth film, he returns unscathed.
  • Heel–Face Turn: At first, he only helps the Autobots when Mikaela threatens to burn his eyes. He later joins the Autobots for real. It's clear that he was only working for the Decepticons out of (justified) fear ("I'm going to be dead without that shard!") and when he learns he doesn't have to work for them, he embraces Sam and his friends.
  • Heroic Sacrifice: He and Brains are able to deactivate some of the Decepticon dropships, but he dies (maybe) while Brains survives.
  • Never Found the Body: Only implied to have been destroyed in the third movie along with Brains. Brains, at least, is shown to have survived in the next movie. He turns up alive and well in ''The Last Knight.
  • It Has Been an Honor: See Famous Last Words.
  • Those Two Guys: In the third film with Brains.
  • What Happened to the Mouse?: Disappears near the end of the second film; by the third film, though, he's living with Sam and Carly.

Introduced in Transformers: Dark of the Moon (2011)

    Brains 
https://static.tvtropes.org/pmwiki/pub/images/dotm_brains_closeup.jpg
Voiced by: Reno Wilson

"Want me to tell ya what I know? I can tell ya about the solar system, all the fun planets to hang out in."

A Decepticon drone that gained sentience, Brains sided with the Autobots and now lives with Wheelie in Sam and Carly's apartment. He transforms into a laptop.


  • A.I. Is a Crapshoot: Heroic example. Was built by the Decepticons, but gained sentience and defected.
  • An Arm and a Leg: When he shows up in AOE, he's missing a leg and walks with a cane.
  • Break the Cutie: While his status as a cutie is debatable, he was a pretty upbeat and fun guy in DOTM. After five years of enslavement and torture, being forced to operate on the bodies of not only dead Decepticons but his dead Autobot friends, as well as enabling Megatron's return, he's pretty broken and doesn't break a sweat when it seems humanity's extinction is nigh. Optimus holds no objection when he apparently bails and just outright leaves the conflict.
  • Cassandra Truth: Brains is the only one who knows of Megatron's plan to manipulate KSI into building him a new body. It doesn't look like Joshua cares much for what he says.
  • Covert Pervert: Carly mentions she found Brains in her underwear drawer. From Sam's reaction, this isn't a rare thing with Brains.
  • Einstein Hair: Made of what look like fibre-optic cables.
  • Genius Ditz: As his name implies, he's supposed to be pretty smart, and Dark of the Moon and Age of Extinction show that he can be, he just needs the proper incentive first.
  • Heel–Face Turn: He was created to be a Decepticon, but quickly had other ideas.
  • Mr. Exposition: His last act in Age Of Extinction is to explain how Megatron was reborn in Galvatron, and just what Galvatron's plans are.
  • Never Found the Body: Only implied to have been destroyed in third movie along with Wheelie. But it's never really shown that they did die. Age of Extinction shows he survives.
  • Nice Guy: Some reviewers even noted that while they were displeased to have another pair of comic relief characters, they actually found Brains quite likable.
  • Those Two Guys: With Wheelie in DOTM.
  • Translator Buddy: What the builders of the man-made Transformers use him for, though "Buddy" is stretching it quite a bit.
  • True Companions: With Wheelie, Sam, and Carly.

    Sentinel Prime 
https://static.tvtropes.org/pmwiki/pub/images/sentinel_prime.png
"For Cybertron! For our home! What war destroyed we can rebuild..."
Voiced by: Leonard Nimoy

"All I ever wanted was the survival of our race."

The leader of the Autobot faction before Optimus Prime, who looks up to him almost as a father with admiration and respect. He transforms into a Rosenbauer fire engine.


  • Adaptational Badass: In earlier incarnations he only existed to get killed by Megatron; then, in Transformers Animated he played the Straw Loser, and then here he fights and wins against Optimus twice.
  • Adaptational Villainy: Even moreso than his counterpart in Animated, since he effectively betrayed the Autobots and is helping the Decepticons to take over Earth.
  • Anti-Villain: Subverted. He paints himself as a Well-Intentioned Extremist, but shows he nothing more than a hypocritical tyrant.
  • Became Their Own Antithesis: Lampshaded by Optimus right before he kills him.
    Sentinel: Optimus, all I ever wanted was the survival of our race. You must see why I had to betray you...
    Optimus: You didn't betray me. You betrayed yourself.
  • Beware the Nice Ones: He's soft-spoken and an elderly mentor to Optimus, but you know crossing him is hazardous to your health considering he's Optimus' teacher. Sure enough, NEST learns this the hard way when he betrays them.
  • BFS: Carries one on his arm.
  • Big Bad: More proactive than Megatron, the other half of the Big Bad Duumvirate. Note that Michael Bay claimed in the lead-up to DOTM that Shockwave would be the Big Bad, possibly as a misinformation campaign to make Sentinel's reveal more shocking.
  • Big "NO!": His last words as Optimus finishes him off.
  • Bastard In Sheep's Clothing: He projects the image of a kindly old mentor when he is in fact a genocidal tyrant corrupted by eons of warfare.
  • Broken Pedestal: Sentinel's betrayal causes Optimus to lose all respect towards his former mentor.
  • Calling the Old Man Out: Optimus does this to Sentinel during their final battle, although he's more of a father figure to him than an actual father.
  • Chronic Backstabbing Disorder: Betrayed the Autobots to join with Megatron, but then betrays Megatron later on (in Megatron's estimation, anyway). Also a literal example, as The Reveal that he's actually with the Decepticons comes with blasting Ironhide In the Back.
  • Classic Villain: Fits all of the criteria as an Ambition and Pride villain.
  • Composite Character: Takes his name from Optimus's predecessor in the Transformers mythos, while his back story as a scientific genius and his overall design seem to be modeled after Alpha Trion. His reveal as a traitor also brings to mind Nova Prime, who was also a Prime who became evil.
  • Cool Old Guy: Subverted. He initially appears to be one, and is certainly treated as such by the rest of the Autobots and most of their human allies, until his true colors are revealed.
  • Deal with the Devil: Inverted. It's arguable that he's the Devil in the relationship, despite him making the deal with Megatron in the first place.
  • Dirty Coward: Shoots Ironhide in the back, and when at the mercy of Optimus tries to save himself by pulling I Did What I Had to Do.
  • Dragon-in-Chief: To Megatron. As Carly points out, he made Megatron his "bitch".
  • Drunk with Power: You know that there is nothing of Optimus Prime's noble father and teacher left when he starts declaring Godhood of Earth.
  • Evil Counterpart: Retroactively, to Jetfire, who betrayed the Decepticons after falling out with their ways and defected to the Autobots; while he had issues with the humans, he was willing to put up with and defend them. Sentinel betrayed the Autobots because he thought they were never going to win the war, and considers himself superior to the humans in every manner.
  • Evil Sounds Deep: After being revealed as a bad guy.
  • Face–Heel Turn: Sentinel actually betrayed the Autobot faction a LONG time ago by siding with Megatron before he started his journey in the Ark. His reanimation basically allowed him to pick up where he left off.
  • Fallen Hero: Was once Optimus's mentor and the leader of the Autobots, but it turns out that he turned traitor.
  • Foreshadowing: "This is the one where Spock goes nuts." Also a case of Fridge Brilliance.
  • A God Am I: "We were Gods once, all of us! But here, there can be only one!
  • Guttural Growler: Talks in low, deep growl. Especially, after he reveals his true colors.
  • Hypocrite: Sentinel states that "the needs of the many outweigh the needs of the few"... conveniently ignoring the fact that there are six billion humans, versus the few hundred or so Cybertronians.
  • I Did What I Had to Do: An injured Sentinel tries to save himself by apologizing to Optimus, begging him to understand why he's done what he felt he had to do. Not surprisingly, it doesn't work.
    Sentinel: Optimus, all I ever wanted was the survival of our race. You must see why I had to betray you...
    Optimus: You didn't betray me. You betrayed yourself.
    Sentinel: NO, Optimus!!!
    [Optimus shoots Sentinel with Megatron's fusion shotgun]
  • Ink-Suit Actor / Comic-Book Fantasy Casting: He looks like 1970s Sean Connery, while having the facial expressions of Leonard Nimoy himself.
  • Kick the Dog: Killing Ironhide.
  • Killed Off for Real: Shot in the head by Optimus.
  • Knight Templar: He struck a deal with Megatron by making plans to use Earth's resources that could be used to replenish Cybertron. This status is also revealed to be influenced by his god complex; remembering how the Cybertronians, particularly the Primes, used to lived like gods. He is also disgusted by how the humans sees the Autobots as simple machines.
  • Laser-Guided Karma: Him shooting Ironhide in the back, as well as his tyrannical and ruling nature, become his undoing, when Megatron does the exact same thing to him at the end of the film, having realized that he would be nothing more than "his bitch".
  • Master Swordsman: He taught Optimus how to use his after all.
  • The Mentor: To Optimus Prime.
  • The Mole: To the Autobots.
  • Off with His Head!: His decapitated head can be seen at the KSI facility in Age of Extinction, with the scientists there pulling data from it to learn more Cybertronian physiology.
  • Offing the Offspring: What he spent most of the war trying to do to Megatron. And what he spent most of Dark of the Moon trying to do to Optimus.
  • Old Soldier: Is capable of taking on the entire Autobot team by himself without breaking a sweat. Also duels Optimus (who by this point has taken out the Driller, Shockwave and a small army of Decepticons with little difficulty) and would have killed him but for Megatron's intervention.
  • One-Man Army: To be expected considering he's mentored the likes of Optimus, Megatron, Shockwave, and Ironhide. In the final battle of Chicago, he takes on the entire non-Wrecker Autobot force and the NEST troops and is clearly winning until the Decepticons' numbers become less and less, leaving him open to more and more enemy fire.
  • Parental Substitute: To Optimus and Megatron. He loses this when he reveals his betrayal.
  • Red Is Heroic: Played straight once.
  • Sealed Good in a Can: Sealed himself in a vault on the Ark for a great many years in stasis until the Autobots revive him. Turns out he was actually Sealed Evil in a Can and betrayed them long ago.
  • Shout-Out: Sentinel has numerous Gundam-like design elements. The most noticeable are the iconic "V" on his forehead, along with his shield, which he even holds in a very Gundam-like fashion.
  • Sir Not-Appearing-in-This-Trailer: Before the film's release, he was not shown in any trailers except for the teaser, although he was shown in toy promotions.
  • Sixth Ranger Traitor: Betrays the Autobots to Megatron.
  • Slasher Smile: He gets an unnerving sneer when he is about to kill Ironhide and reveal his betrayal.
  • The Sociopath: He puts up the facade of a kindly old mentor, but in reality is nothing but a power-hungry lunatic who wants to enslave humanity and plans on betraying Megatron.
  • The Starscream: To the Autobots and later on, Megatron.
  • There Is No Kill Like Overkill: During his final battle with Optimus, he orders all Decepticon ships in Chicago to fire at his former student.
  • Villain Has a Point: He's proven right about his observation that the humans only view Transformers as machines in Age of Extinction, when Joshua Joyce declares the fallen Transformers as "just metal". Though Sentinel is more bemoaning how far the Transformers have fallen from their golden age than anything else—especially for the Primes.
  • Walking Spoiler: The entire plot of Dark of the Moon revolves around him.
  • Well-Intentioned Extremist: His intention of restoring Cybertron was indeed legitimate. Unfortunately, he decided to "defect" to the Decepticons, and presumably use them, as well as launch a massive invasion on Earth with the intention of enslave humanity in order to do so. He also makes clear that although he does intend to restore Cybertron, that does not mean that he intends to let Megatron rule it. However, his A God I Am speech shows he's nothing more than a power-hungry traitor by this point.
  • Wham Line: "Indeed I am. What you must realize, my Autobot brothers, is we were never going to win the war... For the sake of our planet's survival, a deal had to be made... with Megatron."

    Dino/Mirage 

https://static.tvtropes.org/pmwiki/pub/images/img_0132_4.JPG

Voiced by: Francesco Quinn

"On the ground, per favore, and stay there!"

A new member of the team in the third film who speaks with an Italian accent and transforms into a red Ferrari. While he doesn't do much, what little there is of him in the film does have him as a combat partner with Sideswipe.


  • Blade Below the Shoulder: A pair of curved blades on his forearms that he appears to be able to rotate.
  • Cool Car: His alt-mode is a Ferrari 458 Italia
  • Death by Adaptation: Wheeljack's death in the movie is how Mirage died in the novelization, while Wheeljack dies in an entirely different manner.
  • Shout-Out: His name is an homage to Alfredo "Dino" Ferrari, son of the company founder Enzo Ferrari.
  • Sudden Name Change: In Dark of the Moon he is referred to in-film as "Dino", but as "Mirage" in the merchandise and novelization.
  • Toyless Toyline Character: So far his only toys are a small Legion-scale figure which is a Palette Swap of Sideways, and a die-cast which doesn't look like his car mode. (Hasbro has the problem of Mattel retaining the rights for Ferrari toys.) Takara released an extremely movie-accurate retool of Sideways as Dino as part of a celebration of the movie toyline.
  • What Happened to the Mouse?: If the wiki is to be believed, he is the only Autobot whose fate is currently unknown, as he disappeared after DOTM, but hasn't been killed off. Averted in the novelization where Starscream slaughtered him.

    Que/Wheeljack 
Voiced by: George Coe (DOTM); Steve Blum (Bumblebee)

"They're great inventions for kicking ass!"

The Autobots' inventor, Que is first seen handing Ironhide a new gun. Speaks with a vaguely Irish(?) accent. Doesn't really have any awesome moments, but does contribute to others'.


  • Ain't Too Proud to Beg: The poor guy frantically begs for his life and those of his comrades before he's executed.
  • Alien Hair / Einstein Hair: Has glowing fiber-optic cables on his head that increase his resemblance to Albert Einstein.
  • Barrier Warrior: Makes use of an impenetrable force field during the Philadelphia battle in Rising Storm; Fearswoop learns about the "impenetrable" part the hard way.
  • Cool Car: Turns into a Mercedes.
  • Cool Old Guy: He even states he won't let the humans go into battle without his latest kilamajigs.
  • Cruel and Unusual Death: Executed by Soundwave and Barricade despite being unarmed and pleading for mercy.
  • Einstein Hair: His face even resembles Einstein himself.
  • Gadgeteer Genius: He's a genius inventor. Provides Sam with the weapons he ultimately uses to kill Starscream.
  • Killed Mid-Sentence: "Why did you—"(BANG)
  • Non-Action Guy: Rather ironically, given all the weapons he carries on his person. Nonetheless, he's clearly not that great in a straight-up fight, as evidenced by his getting blown up by Shockwave in Rising Storm, and how easily he falls to the 'Cons in Chicago, resorting to begging for his life before Barricade snuffs him out.
  • Shout-Out: To the character Q from the James Bond franchise. He's also a real-life shout out to a certain German scientist.
  • Sudden Name Change: In ''Dark of the Moon he is referred to in-film as "Que", but as "Wheeljack" in the merchandise and novelization.
  • You Don't Look Like You: Tell a faithful Transformers fan that this is meant to be Wheeljack. Go on, try it.

    The Wreckers 

Leadfoot, Roadbuster, and Topspin

Voiced by: John DiMaggio (Leadfoot), Ron Bottitta (Roadbuster), and Steven Barr (Topsin, credited as Volleybot)

"This is going to hurt... a lot!"

Mechanical engineers, warriors, and (according to the novelization) NASCAR fans, the Wreckers were left to look after an Autobot ship in NASA custody. They transform into NASCAR stock cars that are festooned with guns.


  • The Bus Came Back: After being absent in Age Of Extinction, Roadbuster and Topspin return in The Last Knight, having been granted asylum in Cuba with Simmons.
  • Chromatic Arrangement: Leadfoot, the leader and most prominent of the Wreckers, is the red one (because his NASCAR alt-mode advertises Target).
  • Cool Shades: All three constantly wear these.
  • Jerkass: This is explained as why they aren't active with the other Autobots; they don't get along well with humans.
    Mearing: These guys are the Wreckers. We don't let 'em off the base much, 'cause they're assholes.
  • Jerk with a Heart of Gold: Despite that, they're all for defending humanity with the other Autobots. Leadfoot even reassures Sam that "We ain't goin' nowhere."
  • Killed Off for Real: Leadfoot was killed by Cemetary Wind, as shown in an audio recording in Age Of Extinction.
  • Suddenly Voiced: Topspin speaks in The Last Knight.
  • Violent Glaswegian: Leadfoot and Roadbuster both have Scottish accents, and if you need proof of the "violent" bit, there's how they kill that Decepticon pilot at the beginning of the Final Battle...
  • The Voiceless: Topspin, until averted in The Last Knight.
  • Weaponized Car: Their alternate modes seem to automatically be like this—weaponized NASCAR Sprint Cup Series Chevrolet Impalas: Topspin becomes the #48 of Jimmie Johnson, Leadfoot becomes the #42 of Juan Pablo Montoya, and Roadbuster becomes the #88 of Dale Earnhardt, Jr. These alternate modes also appeared in the parade laps for the 2011 Daytona 500.
  • What Happened to the Mouse?: Apart from Leadfoot's death, Roadbuster and Topspin were not heard from since. The Last Knight reveals that the latter two have survived, currently under Simmons' watch.

    Hound 
https://static.tvtropes.org/pmwiki/pub/images/300px-tf4hound_8458.jpg
"I’m like a fat ballerina, who takes scalps and slits throats!"

Voiced by: John Goodman

"We got the gang back together!"

Introduced in the fourth film as a new member of Optimus's team, Hound transforms into a Oshkosh Defense Medium Tactical Vehicle.


  • Acrofatic: Being that big doesn't really slow him down. As he puts it:
    Hound: I'm like a fat ballerina! Who takes scalps and slits throats!
  • Adaptational Badass: He's a grenade-chucking, pistol-firing blend of Bulkhead, Ironhide, Roadbuster, and Kup. He fits the bill.
  • Author Avatar: His obese figure could be a self-reference to John Goodman.
  • Badass Beard: It may even put Sentinel's to shame.
  • Big Fun: Despite being an armory on legs, he's rather jolly, and even dances with Bumblebee and Tessa in a deleted scene.
  • The Big Guy: He's the most powerful Autobot besides Optimus and the Dinobots, and is a dead ringer for the trope personality-wise. He shares the role with the less conventional Drift.
  • Boisterous Bruiser
  • Bruiser with a Soft Center: Regardless how trigger-happy he may be, it's clear that Hound cares for his Autobot comrades like a family, and, while he despises humans at first due to their involvement in the deaths of his friends, comes to accept Cade, Tessa, and Shane as part of his family too.
  • Cigar Chomper: The bullet he holds in his mouth evokes this.
  • Composite Character: He's named after G1 Hound, but he seems more based on Bulkhead of Transformers Animated and Transformers Prime, being a big, green, friendly bulky guy, with a bit of Kup and Roadbuster from G1 thrown in.
  • Combat Pragmatist: When pushed, this fat ballerina proves how damn good he is at this.
  • Due to the Dead: Sadly takes off his hat and places it over his Spark when he learns of Leadfoot's death.
  • Firing in the Air a Lot: His introduction sees him so overjoyed at Optimus's return that he pulls out a gun and lets off several rounds.
    Hound: Oh yeah! Hell yeah! He's back! He's alive! [fires in the air a lot] Optimus is here!!
  • Gatling Good: His default weapon is a powerful triple barreled mini gun.
    • More Dakka: ...And by "triple barreled" we mean three separate 6-barreled mini guns, in a triangular set-up.
  • Hurting Hero: The loss of Leadfoot, Ratchet and the other Autobots has gotten to him.
  • Improbable Weapon User As he runs out of ammo, he ends up throwing his Nice Hat at the oncoming Vehicon onslaught, using his belt as a melee weapon, and (quite awesomely) firing his bullet-cigar out of his mouth into the face of a Vehicon.
  • Ink-Suit Actor: Looks quite a bit like John Goodman himself.
  • Made of Iron: Hound stands of being one of the few characters to take a direct hit from Megatron's gun and live to tell the tale.
  • No Man Left Behind: He's completely unwilling to abandon his fellow Autobots or Cade on the battlefield, and he's the one who takes the time to free the oft-forgotten Brains.
  • Stepford Smiler: Implied during the scene where the group learns of Leadfoot's death. Hound had been jovial until Optimus asked if they knew of any other survivors, and immediately gets very quiet and soft-spoken. His voice nearly breaks when he sees footage of Leadfoot being killed, and he quietly curses the humans responsible. He remains this way until Optimus declares he plans to kill Attinger.
  • Undying Loyalty: To Optimus.
  • Walking Armory: He carries a multitude of guns and explosives that he uses to great effect, though it it isn't quite enough to take care of the dozens of Vehicons he fights in Hong Kong. By the time the movie ends, he is completely out of ammo, and forced to rely on whatever he has on his person to keep fighting. His toy likewise features a total of eight weapons, in contrast to the one or two that most other toys come with.

    Crosshairs 
https://static.tvtropes.org/pmwiki/pub/images/img_0384.PNG
"Nah! This isn’t our fight! I’m done being an underdog. Underdogs suck! I say they get what they deserve."

Voiced by: John DiMaggio

"I'm unclear. What's in it for me?"

Introduced in the fourth film, Crosshairs is a paratrooper who transforms into a green 2014 Chevrolet Corvette C7 Stingray.


  • Anti-Hero: At the end of the day, Crosshairs is a good person but is also very selfish and distrustful of humans. When the Autobots sneak onboard Lockdown's spaceship to save Optimus and Tessa, Crosshairs does not want to save Tessa until Hound forces him to cooperate. Justified because of The Purge.
  • Awesome Aussie: Has a bit of this.
  • Badass Baritone: Comes with being voiced by John DiMaggio.
  • Badass Longcoat: His alternate mode kibble forms a long, flowing duster. In old-style Transformers that's called shell-forming and is a sign of bad transforming design. Just this once, though, it's awesome.
  • Blood Knight: He certainly has fun flipping through the skies of Chicago and gunning down Decepticons.
  • Composite Character: In addition to taking some cues from Sideswipe (Blood Knight antics, Corvette Stingray altmode) he also draws heavy inspiration from Rattrap (somewhat disrespectful toward the team leader, a expert saboteur, Deadpan Snarker tendencies).
  • Deadpan Snarker: One of the biggest. Essentially he's Damon Baird if John Di Maggio voiced him.
  • Guns Akimbo: During the battle in Chicago he proceeds to do this while descending from the skies, parachutes deployed. See here.
  • It's Raining Men: He's the Autobots' paratrooper.
  • Jerk with a Heart of Gold: Much like the Wreckers, he's an asshole, but he'll come through in the end. Perfectly exemplified when the Autobots' ship crashes and he realizes the Autobots are outnumbered ten to one: he immediately declares that it isn't their fight and says he's sick of fighting against impossible odds, then he asks Optimus what they're going to do next, clearly ready to follow no matter whatever his leader decides.
    Crosshairs: Nah! This isn't our fight! I'm done being an underdog. Underdogs suck! I say they get what they deserve. What's the play, Prime?
  • The Lancer/The Smart Guy: Pulls double duty on the Five-Man Band, due to having both the most technical prowess and the most disagreeable temperament.
  • Oh, Crap!: When Grimlock transforms into a Tyrannosaurus for the first time. He hastily tries to climb away from the battle even further.
  • Screw This, I'm Outta Here!: Generally his approach when faced with a situation he doesn't like. When aboard Lockdown's ship, he quickly tries to get the others to bail with him. Hound has to threaten to kill him to get him to stay and help. Later, in a lesser example, he quickly scrambles to the sidelines when Optimus and Grimlock are going at it.

    Drift 
https://static.tvtropes.org/pmwiki/pub/images/img_0385.PNG

Voiced by: Ken Watanabe

"Hound, find your inner compass. Loyalty is but a flower in the winds of fear and temptation."

An Autobot tactician and a former Decepticon who transforms into a black and blue 2013 Bugatti Veyron Grand Sport Vitesse, as well as an unspecified attack helicopter.


  • Composite Character: He is a former Decepticon and wields twin swords like G1 Drift, and is a Triple Changer with a car mode and an helicopter mode like G1 Springer.
  • Cool Car: A Bugatti Veyron Grand Sport Vitesse, and in the fifth film a Mercedes-AMG GT-R.
  • Dual Wielding: Has two samurai swords that he stows on his back. On a larger scale, he's a Triplechanger, transforming into both a car and a helicopter.
  • Everything's Better with Samurai: His robot mode is essentially a robotic samurai.
  • Headbutting Heroes: Drift threatens to cross blades with Hound when he is provoked, and also scraps briefly with Bumblebee when calling the latter out on his lack of discipline.
  • Heel–Face Turn: Pulled one before the events of the fourth film. However, he still resents the fact that he's had to tolerate Bumblebee's attempts at leadership, as he views the young Autobot as inexperienced and unfit to lead.
  • Ink-Suit Actor: He only lacks the facial hair.
  • Mood-Swinger: Quite a few instances where Drift goes from calm and soft-spoken to violent and manic at the drop of a hat. Perhaps he hasn't forgone all his Decepticon connections.
  • Not So Stoic: When spooked by a captive creature on Lockdown's ship, he quickly hacks it to death in a panic, immediately after admonishing the others to save violence as a last resort.
  • Only Sane Man: With Optimus becoming more emotionally volatile, Hound being a bit too boisterous for his own good, Crosshairs being a self-serving jerk, and Bumblebee having a fragile ego to go with his lack of maturity, Drift is this among the surviving Autobots.
  • The Stoic: He's very soft-spoken, but see Not So Stoic.
  • The Strategist: Also indicated in his toy bio.
  • Throwing Your Sword Always Works: During the battle of Hong Kong, he destroys a Vehicon by flinging one of his swords through it. He fails to retrieve it and is down to one sword in TLK.
  • Undying Loyalty: To his sensei, Optimus.
  • Warrior Poet: He recites a Japanese haiku while lamenting the Autobots's situation.
  • Wrong Genre Savvy: He thought that Grimlock's alt mode was going to be a "giant car". Justified in his case, as up until the Dinobots reveal, the only Transformers with animal alt-modes were the much smaller Ravage (who may not have even had an alt-mode) and Laserbeak.

    The Dinobots 

Appearing in the Movie: Grimlock, Strafe, Slug, and Scorn

Other members: Slash, Slog, Snarl

https://static.tvtropes.org/pmwiki/pub/images/800px_aoe_dinobotsbravewarriors.jpg

  • Adaptation Name Change: Slug the Triceratops was originally Slagnote . Slog the Brontosaurus was originally Sludge. Slag's name has been "officially" changed to Slug since 2007, mainly because of a case of his name meaning "slut" in the United Kingdom.
  • Alphabetical Theme Naming: All of their names apart from Grimlock start with the letter S.
  • Badass Crew: They curbstomp Galvatron's army in Age of Extinction.
  • Badass in Distress: They briefly become this when Lockdown attempts to recapture them with his ship.
  • Breath Weapon: Grimlock is shown having a fiery breath that can burn Transformers.
  • Canon Foreigner / Canon Immigrant / God-Created Canon Foreigner: Strafe, Slash and Scorn. Strafe is a semi-Expy of Swoop, but Scorn and Slash are both completely new characters, and there were never any theropod-based Dinobots aside from Grimlock. Slash could be a heavily-modified semi-Expy of Dinobot (who also has a dromaeosaur alt-mode), and Scorn one of ''Cybertron'' Undermine.
  • Chuck Cunningham Syndrome: Grimlock and Slug are present in the early part of The Last Knight, only to vanish after the Decepticon attack on Cade's junkyard.
  • Color-Coded for Your Convenience: Unlike the film, each of the Dinobots' toys sport a unique color instead of being metallic grey.
    • Grimlock — Gold with silver highlights.
    • Scorn — Red with orange highlights.
    • Slug — Purple with red highlights.
    • Slash — Light blue with yellow highlights.
    • Strafe — Dark blue with silver highlights.
    • Slog — Black with red highlights.
    • Snarl — Green with purple highlights.
  • Everything's Better with Dinosaurs: They're Dinobots, come on. Every moment with them onscreen is made to look awesome as much as possible.
  • Death from Above: Strafe is a giant, two-headed Pteranodon in his dino-mode and commonly employs this tactic.
    • Scorn is shown entering the fray by leaping into the air and landing back-first on enemy transformers, impaling them on his spines.
  • Defeat Means Friendship: Optimus has to smack around Grimlock, the leader, for the rest of the Dinobots to follow his lead.
  • Dinosaurs Are Dragons: All of them have designs that invoke a draconic appearance to them. And hey, Grimlock breathes fire.
  • Dual Wielding: Most of their toys. Grimlock is the only one to wield a single weapon.
  • Dumb Muscle: They don't seem to be very intelligent, but are significantly larger (Grimlock is at least twice the size of Optimus) and more physically powerful than most other Transformers.
    • Slog, whose bio describes him as, "Low on brainpower, even by Dinobot standards". However, he's still the biggest and one of the physically strongest of the Dinobots. This is consistent with the classic depiction of Sludge (who Slog was initially intended to be), who also transforms into a Brontosaurus and is typically portrayed as the largest and dumbest Dinobot.
  • Famed In-Story: Implied. Upon seeing Grimlock, Optimus says (in Cybertonian) "The legend exists." Pretty blatantly stated when Optimus shows them to Drift and Crosshairs, calling them "legendary warriors."
  • Giant Flyer: Strafe. He's big enough to have two car-sized Transformersnote  fighting on his back at once.
  • I'm a Humanitarian: Or, as the case may be, a Cybertronarian. The Dinobots munch their way through enemies just as much as they smash. Grimlock even eats Dreadbot in The Last Knight.
  • The Juggernaut: Scorn, apparently. According to his toy's bio "His massive size makes him almost impossible to bring down."
  • Kaiju: The Dinobots' beast modes are huge - Grimlock is as large compared to Optimus as a normal T. rex is compared to a human.
  • Kill It with Fire: As stated previously, Grimlock has fire breath in Dino-mode that is hot enough to cook Transformers.
  • Knight in Shining Armor: All of the Dinobots' robot modes resemble armored knights. Grimlock and Scorn's designs carry a particular samurai flair as well.
  • Large and in Charge: Subverted—Grimlock is obstensibly the leader, but is only the second largest. True to life, Scorn the Spinosaurus dwarfs the other three. Likely to be subverted even more once Slog appears on screen, as even though the Brachiosaurus isn't the biggest of the sauropods, it's still far bigger than a Spinosaurus.
  • Multiple Head Case: Strafe is a pterosaur with two heads.
  • Single Specimen Species: Averted with Slash in concept art (see Men of Sherwood).
  • Spike Shooter: Scorn is depicted doing this in concept art.
  • Stock Dinosaurs: Albeit with each one having an element of the fantastic.
    • Pterosoar: Strafe is a two-headed pterosaur.
    • Tyrannosaurus rex: Grimlock is a horned T. rex.
    • Raptor Attack: Slash is a dromaeosaurid with metal "feathers" covering his body.
    • Slug is a Triceratops with a spiked tail (the spikes possibly being a stand-in for the quills Triceratops might have had in real life).
    • Scorn is a Spinosaurus with multiple sails.
    • Slog is a Brachiosaurus with rows of spikes along his back.
    • Snarl is a Stegosaurus with... not much different from a regular Stegosaurus aside from being robotic.
  • The Voiceless: None of them say a word. It's not clear if they even can speak, but Grimlock seems to understand what Optimus is saying.
    • Averted in the toyline. Grimlock's Electronic Titan Toy has a voice chip, with lines provided by Gregg Berger, Grimlock's original voice actor from the original cartoon.
  • Weapon of Choice: Each of them has a specific weapon (or two) in Robot mode.
  • What Happened to the Mouse?:
    • When the first information on Age of Extinction was revealed, there were seven Dinobots and their alt-modes named. Slash, Slognote , and Snarl are nowhere to be seen in the film.
    • In TLK, all the Dinobots but Grimlock and Slug are absent, without comment or explanation.

Introduced in Transformers: The Last Knight (2017)

    Hot Rod 
Voiced by: Omar Sy

  • Bash Brothers: Described to be one with Bumblebee.
  • Cool Car: He's a Lamborghini Aventador Centenario, a limited-edition 770hp Aventador created to commemorate Ferrucio Lamborghini's 100th annivesary. So yes, he's basically a Good Counterpart to Lockdown alt-mode wise.
  • French Jerk: He has been described as arrogant, and speaks with a French accent. However, it turns out that the accent is not his choice, and he cannot turn it off, downplaying this somewhat.
  • Jerk with a Heart of Gold: He's also described as "brash but noble". Such an example is him addressing Vivian as "lady", even while the latter is hitting him with a broom.
  • Time Stands Still: His Weapon of Choice can create a localized temporal rift.
  • You Don't Look Like You: His design greatly differs from any of his previous incarnations. While design changes for the films are largely accepted by now, he is notable for having no visual resemblance to original Hot Rod.

    Sqweeks 
Voiced by: Reno Wilson

     Daytrader 
A junk collector.

    Canopy 
Voiced by: Frank Welker

  • Advertised Extra: Has been shown in a few promotions, only for his death to occur early in the film.
  • Canon Foreigner: He was created exclusively for the film; he has no counterpart in any other media.

    Knights of Iacon / Dragonstorm 

A group of Cybertronian knights, who landed on Earth in the fourth century AC, in Britain. Allying with Arthur, the twelve knights can combine into one gigantic three-headed dragon.

  • An Axe to Grind: Some of them wield axes instead of swords.
  • Been There, Shaped History: They helped make legends of King Arthur and Merlin, and inspired the Knights of the Round Table.
  • Combining Mecha: Twelve bots who combine into one alt-mode.
  • Humans Are Special: They beat Optimus to the punch by over a thousand years, seeing mankind for their potential.
  • Instant Awesome: Just Add Dragons!: Dragonstorm, their combined alt-mode. Although most of Vivianne's lecture in the beginning turned out to be bogus, she was right about one thing: the dragon is awesome.
  • Knight in Shining Armor: Their look in robot mode (minus the odd bit of patina after a thousand years sleep).
  • Palette Swap: The Knights all share a similar build in robot mode, outside of slightly different proportions, and different colour-schemes.

     Trench 
An Autobot who transforms into a Cat 320 excavator taking refuge from the TRF. Due to his limited screen time, he's the "Jolt" of The Last Knight.

  • Dull Surprise: When Grimlock approaches him snarling, he still remains intact.
  • Screw This, I'm Outta Here!: Bails out of the Autobot improvised headquarters in a junkyard when Bumblebee accidentally gave away the location by failing to notice a tracker that the TRF put on him.
  • The Voiceless: Doesn't have any lines.
