Optimus Prime

"My name... is Optimus Prime, and I'm prepared to sacrifice my life to defend the Allspark."

The leader of a small maintenance crew, Optimus Prime is a well-meaning young 'bot who dreams of a bigger, more heroic lifestyle. He gets his wish when his crew stumbles upon the elusive Allspark. A run-in with Megatron and his Decepticon crew causes Prime and his crew to land on Earth where they try to adapt while saving the world on a daily basis. Though Optimus gets the "hero" life he asked for, he is inexperienced. He's a nice guy who does the best he can despite some insecurity and reluctance.

"Fastest thing on wheels, coming through!"

Bumblebee is a speedy, impatient, and impulsive young Cybertronian. He thinks on his wheels and less on his head and tends to goof-up and have fun with his human friend, Sari. Despite it, he's ready for battle when the situation calls, even if he tends to rush in without thinking first.

  • Berserk Button: Downplayed. It's not as bad as Edward Elric, but he really doesn't like being called short.
  • Big Brother Instinct: Towards Sari.
  • Bratty Half-Pint
  • Child Soldier: "Human Error" indicates that he's mentally around the same age as Sari.
  • Four-Temperament Ensemble: The Sanguine.
  • Fragile Speedster: What he lacks in size, strength and power, he makes up for in speed.
  • Freudian Excuse: Non-villainous example: his attitude towards teamwork makes a lot more sense once you've seen "Autoboot Camp". Everyone but Bulkhead and Longarm treated him like slag, and helping out Bulkhead tanked his career.
  • Hot-Blooded
  • Jet Pack: His turbo-boosters can work like this, though he needs someone to get him into the air first.
  • Keet: About as much as a robot can be.
  • Kid-Appeal Character: The former Trope Namer.
  • Leeroy Jenkins
  • The Load: While he is okay at fighting human super-villains, he is utterly useless when fighting Decepticons on his own, as his one weapon (nodes that shoot out beams of electricity) are too weak to even make any of them flinch. Well, until he gets the limiters on them taken off and they become the most powerful weapon on the entire team.
  • Reassignment Backfire: Space Bridge maintenance is largely considered a crap job, especially with Elite Guard aspirations. Then he and the rest find the MacGuffin that catapults him and the rest into the positions of the most important robots on Cybertron.
  • Red Oni, Blue Oni: The red to Prowl's blue.
  • Rollerblade Good
  • Shock and Awe: His stingers.
  • Shooting Superman: Before his stingers were set to their full power setting, he may as well have been throwing tennis balls at the 'Cons.
  • Took a Level in Badass: Ratchet sets his stingers to the full-power setting intended for combat bots. After this, his stingers do become a genuinely useful weapon.
  • Unwitting Pawn: Of Shockwave.
  • Whack A Mole


"You guys got it easy. All people want me to do is break stuff. I've got a sensitive side too, you know... but breaking stuff is kinda fun."

Bulkhead may be big and strong and he may enjoy smashing things around here and there, but he wants you to know he has a sensitive side, too. Ever the Gentle Giant, he is often taken for granted, thinking because of his brawny nature, he isn't all that smart. Though unsubtle, Bulkhead is an insightful 'bot with a natural gift for art.

"It's not that I don't want to remember. I have to remember - for those who can't."

Ratchet suffered through the Great War millions of years back, experiences which have caused him to be grumpy 24/7. He refuses to talk about his time there (especially with an eager Optimus Prime) and suffers Vietnam-style flashbacks due primarily to two traumatic incidents of failing in his profession: accidentally wiping Arcee's memory core and having to participate in the near-death of Omega Supreme that reduced the giant to a mere spaceship. Despite his constant angry outbursts, however, Ratchet possesses a sweet side deep down.

"Stillness... then strike."

Prowl is a lone Ninja-Bot who doesn't play well with others, preferring to rely on only himself. Stuck with Optimus and crew, he is forced to learn how to work as part of a team. Prowl is sneaky and clever due to his occupation and spends countless hours meditating. He enjoys observing nature and the organic life that most of his kind fear. He later develops from a stoic warrior into a true hero.

"Wipe my memory core. Ratchet, the access codes in my processor are crucial to the war effort. If Megatron gets them..."

Formerly a schoolteacher to young Autobots, Arcee became an intel courier during the Great War, tasked with carrying the important codes for Project: Omega, a valuable resource that the Decepticons wanted. This job came to an abrupt end when Ratchet accidentally wiped her memory during the Great War, causing her to suffer amnesia. She isn't seen until later on when Megatron and crew manage to get their hands on her and the code. Fortunately, Sari and Ratchet restore her memory afterwards.


"Dinobots rule!"

Grimlock is the leader of the Dinobots. He and the other Dinobots are simpleminded and aggressive creatures who started out as animatronic dinosaurs for a theme park, which Megatron upgraded with weapons in the hopes of using one of them as a new body. This plan went off the rails when they were brought to life in an accident involving the Key. They tend to get violent very fast the moment they sense hostility, and Prowl is the only one who can calm them down...usually.

Snarl and Swoop

Sentinel Prime

Voiced by: Townsend Coleman / Junichi Suwabe

"If I need a trash-can emptied or a floor mopped, I'll call on my buddy Optimus Prime. Or should I say "Maintenance Prime"?"

Sentinel Prime is, plain and simple, a jerkass. He is an egotistical, boisterous bot who uses his high position to issue orders and command high respect, especially towards Optimus (despite sharing the same rank). Years back, the two and Elita-1 were best friends until an incident on a foreign organic planet, during which Elita was separated from them and assumed dead. Their relationship has been strained since.

  • Aesop Amnesia: Tends to suffer from this thanks to his ego.
  • Asshole Victim: Of a similar type to Archer. If something bad happens to him, he's probably done something to make it hard to feel sympathy.
  • Anti-Hero
    • Nominal Hero: If his general characterization doesn't establish him as this, then his actions in "Five Servos Of Doom" and "Predacons Rising" certainly do.
  • Break the Cutie: The flashbacks to "Along Came a Spider" show he was a nice (if somewhat smug) guy who considered Optimus his friend. What happened to Elita-1 broke him.
  • Break the Haughty: He goes through several Humiliation Congas, including having his head cut off and body taken, losing prisoners on his watch and having his ship taken over (then beaten flung and frozen), getting a beating from his friends, accidentally, when a Starscream clone uses him as a shield. Ultimately, this does nothing to reduce his arrogance, it does however, repair his relationship with Optimus, as he finally stops blaming Optimus for Elita-1's fate, and even helps him on Cybertron (even if he does give him some digs about Toxitron looking like him).
  • Butt Monkey: If you get annoyed at him, just wait five minutes and something nasty will happen to him. Usually it's related to Earth's weather/inhabitants/road structure, but he's also had his body stolen by a human, been humiliated in front of his comrades, screamed like a little girl when encountering organics, failed at driving in the rain, and been wrong in pretty much every arrogant assertion he's made.
  • Drill Sergeant Nasty: Back when he was a sergeant.
  • Drives Like Crazy: He assumes traffic laws only apply to organics. Thus, he'll run every light, cut through cross traffic, run over parked cars, gets a stop sign jammed in his grill, and during his first drive on Earth, he drove himself off an unfinished overpass.
  • Dumbass Has a Point: In "Five Servos Of Doom", Prowl takes the fact that the primary mods of his prisoners are not on the prisoners as evidence that Sentinel had help from Lockdown. Sentinel shows him the mods then points out that he'd have to be pretty stupid to let his prisoners keep explosives on them (if only because he's already let it happen).
  • Early Installment Weirdness: His head (which was the only part of him that they had designed at that point) has a different design in "Transform and Roll Out!" Interestingly, when the series was aired on the Hub in 2012 and in Shout Factory's 2014 DVD release of the full series, they changed the animation in this scene to match his final head design.
  • Entitled Bastard
  • Expy: Several of his design elements (he's energetic, mostly blue, with a very prominent chin) are based on The Tick, with whom he shares a voice actor. This was done on purpose after said actor was cast for the role.
  • Fantastic Racism: Towards organics. He has a bigger problem with Blackarachnia's organic nature than even Blackarachnia.
  • Glory Hound
  • Good Is Not Nice
  • Jerkass: By no stretch of the imagination is Sentinel an okay guy, though at least some of this can be traced to what happened with Elita-1 and the spiders. He is basically what one would get if Zapp Branigan turned into a robot and then became a New Testament Pharisee.
    • Jerk With A Heart Of Jerk: A crowning example of one. Just when we think he may have redeeming qualities, he tries to destroy Elita-1 when she's become part organic.
  • Jerkass Has a Point: See Dumbass Has a Point
    • His whole approach to Blackarachnia is based on Fantastic Racism, but considering some of her actions, he has a point when he says "Elita-1 went off-line a long time ago."
  • Karma Houdini Warranty: In "Endgame: Part 1", in a flashback, Optimus is shown taking the fall for the Elita-1 incident, even though it was Sentinel's idea to go to the organic planet in the first place. As a result, Optimus gets expelled from Autobot Academy, while Sentinel goes on to become a member of the Elite Guard. Karma catches up with him when the Elite Guard arrive on Earth and Sentinel is subjected to frequent humiliations due to his arrogance, contempt of the human race and general Jerkass behaviour. Furthermore, in "This Is Why I Hate Machines", when Sentinel attempts to defeat the 'cons, putting the whole planet at risk, the Cybertron High Council actually call Sentinel out for his reckless actions, though are unable to demote him as 'acting Magnus'. By the end of the series, when Optimus and his crew return to Cybertron with Megatron, Shockwave and Lugnut as prisoners, Sentinel stands glowering amidst a huge crowd of cheering Autobots.
  • Lantern Jaw of Justice: Moreso than any other and it's his Berserk Button.
  • Laser Blade: His lightsaber-esque lance.
  • Luckily My Shield Will Protect Me: It can sprout spikes and expand into a wall (or even a bubble).
  • The Neidermeyer: A classical example, complete with delusions of competence. Handled a little differently in that he does suffer for his screw-ups, even if he retains Ultimate Job Security.
  • Never My Fault: How he reacted to the Elita-1 incident. Optimus did prevent him from going back for her, but the whole trip was his idea in the first place, and Elita-1 was just as eager to tag along. Optimus tried to talk them both out of it.
    "This is all your fault!"
  • Noble Bigot with a Badge: Emphasis on "Bigot".
  • Oh Slag: Says this as a tower falls on him, during a flashback in the episode "Autoboot Camp".
  • Pet the Dog: He does get one or two such moments during the series, usually brought on by Optimus.
  • Politically Incorrect Hero: He's terrified of organics.
  • Red Oni, Blue Oni: The red to Optimus' blue.
  • Screams Like a Little Girl
  • Why Did It Have To Be Organics?


"The classic Metallikato "Five Servos of Doom" attack! But have you seen this one?"

Jazz is calm and collected and just plain cool. He is a graduate of the Cyber-Ninja Corps and later on, befriends fellow ninja Prowl. Jazz, like Prowl, has an interest in organic life.

Supreme Commander Ultra Magnus

"We're at war, soldier. We do what we must."

Current leader of the Autobots, Ultra Magnus is a straightforward leader. He usually makes decisions that would benefit the Autobots no matter how unethical they may seem, though he has his soft spots, mainly concerning Optimus Prime, in whom he sees potential. He is tragically damaged by traitor Longarm Prime aka Shockwave, and according to the Allspark Almanac, dies would have died in season four, making his current position nebulous.

  • Authority Equals Asskicking
  • Big Good
  • Celebrity Impersonator: Jeff Bennett does a pretty good impersonation of G1 Ultra Magnus from The Movie (Robert Stack, if you wanted to know).
  • Drop the Hammer
  • Expy: Whoever holds this hammer, if they can deal with that now, shall posses the power of the Magnus... One could say the Magnus Hammer is basically an Expy of Mjolnir, and Animated Ultra Magnus is basically Thor for wielding it. Also, the hammer is the symbol of office for the Magnus, since in this continuity the suffix "Magnus" is a military rank, and they must have the hammer in their possesion at all times to be considered the Magnus similar to Mjolnir only granting the power of Thor to whom it deems worthy.
  • The Extremist Was Right: Using the supplementary materials and the Transwarped three-parter, Ultra Magnus was this for the war, instituting a draft and creating the super robots with reduced minds so they wouldn't question the destruction they'd bring. Considering that blowing up a planet was considered a Decepticon victory, and the death toll, his actions aren't unreasonable. He also has the ability to rein it in, and stop before his methods get too extreme, unlike Sentinel.
  • Good Is Not Soft: He has made some very questionable decisions during his regime, but he's still unquestionably a hero.
  • Horrible Judge of Character: Optimus willingly took the blame for the Elita-1 incident, but that doesn't quite explain how Sentinel ended up as Magnus's right hand guy.
  • Large And In Charge: The tallest non-Omega Sentinel Autobot on the show.
  • Reasonable Authority Figure: He pulled a lot of strings to get Optimus his rank and command.
  • Shock and Awe: The Magnus Hammer can summon lightning, Thor-style.
  • Supporting Leader
  • The Worf Effect: Leader and one of the most powerful of the Autobots, capable of raining thunder down from the sky. In his only onscreen fight with a Decepticon Starscream cheap shotted him in the face and knocked him out. Then Shockwave critically injures him offscreen.


"Did someone say hero? I am Wreck-Gar! I am a hero!"

Wreck-Gar means well, he really does. When he first arrives, he has no idea who he is and what his purpose in life is. He spends the entire episode switching between hero and villain in an effort to find what his life goal is, though in a somewhat unintentional manner. Wreck-Gar literally does whatever he is told — good or bad — with hilarious results. He later becomes an Autobot and tries his darnedest to be the hero he would like to be. His head may not be in the right place, but his spark is.

Omega Supreme

Voiced by: Kevin Michael Richardson (season two), Phil LaMarr (season three) / Tessho Genda


The current ship of Optimus Prime's crew, Omega Supreme was part of a huge project against the Decepticons during the Great War. He nearly lost his spark during the Final Battle and ended up comatose in ship form. Ratchet is his linked partner and constantly keeps him well maintained.

  • Badass
  • Badass Baritone
  • Cool Starship: At first glance, a beat-up repair ship. In reality, an Autobot war machine.
  • Dumb Muscle: He was deliberately designed with a simplistic processor to prevent him questioning the commands of his mentor-bot...or thinking too hard about the amount of deaths he'd be responsible for.
  • Giant Robot
  • Heroic Sacrifice: Twice. He survives both of them, but the first one puts him in modified stasis for millions of years.
  • I Am Not a Gun: Omega and the other sentinels were built to be war-ending WMDs by desperate Autobots. While Omega couldn't avoid this, he was at least able to reflect on the contradiction of his actions.
    Omega: You taught me to protect like an Autobot, but all I did was destroy like a Decepticon
    Ratchet: We do what we must...even if sometimes it doesn't make sense.
  • It's What I Do: "I am programmed to protect... and sacrifice, if necessary."
  • Last of His Kind: Omega is the last surviving and active Omega Sentinel, with Steelhaven/Sigma Supreme being used as a regular spaceship.
  • Meaningful Echo: "We do what we must, even if it sometimes doesn't make sense."
  • Meta Mecha
  • Person of Mass Destruction
  • Sapient Ship
  • Toyless Toyline Character
  • Weapon of Choice

Wasp / Waspinator

Voiced by: Tom Kenny / Kenji Nojima (as Wasp), Kenso Kata (as Waspinator)

"Wasp not thing, Wasp upgrade! Spider-bot Wasp friend... make Wasp powerful... make Wasp... Waspinator!"

A former Autobot who worked alongside Bumblebee and Bulkhead in Autoboot Camp, Wasp is a cocky little guy who often got on the latters' nerves. After overhearing a Decepticon spy communicating with Megatron, Bumblebee accused Wasp of being said spy, leading to his imprisonment—thanks to some evidence planted by the real deal. Wasp eventually escapes (again with the help of the real spy) but he's not the bot he used to be. One thing is clear: He will get his revenge on Bumblebee!


Voiced by: John Moschitta (another G1 reprisal) / Takahiro Sakurai


Blurr is a member of the Autobot Elite Guard—specifically, a spy tasked with watching over Optimus and crew. With his lightning-fast speed (and speech), no one can keep him down ...except Shockwave.

  • Adaptational Badass: Generation One Blurr: comic relief. Animated Blurr: a very powerful and agile member of the Elite Guard.]
  • Back from the Dead: While it's arguable whether he was actually dead per se, The Return of Blurr gives him back a body instead of being trapped in the cube.
  • Chainsaw Good: The weapon his action figure comes with. It doesn't show up in the series, unfortunately.
  • Determinator: If he has a message important enough, he will traverse the galaxy on wheels to get it to Cybertron.
  • Family-Unfriendly Death / Droppeda Bridgeon Him
    • And I Must Scream: A fan theory, and the fact that his cube is still glowing blue, is that he is still alive like that. Or was until he hit the incinerator.
      • The comics show he escaped the incinerator. But his spark is still trapped in the cube until the events of The Return of Blurr, in which he gets a new body.
    • Earlier, in 'Velocity', he's shown to have been under Master Disaster's control via an AllSpark fragment in a remote, presumably while conscious. Poor guy barely gets a break in this series.
  • He Knows Too Much
  • Hypercompetent Sidekick: to Longarm.
  • Motor Mouth
  • Sacrificial Lion
  • Suddenly Voiced: Does not speak or transform during his first appearance while under Master of Disaster's control.

Jetfire and Jetstorm

Jetfire voiced by: Tom Kenny / Kappei Yamaguchi
Jetstorm voiced by: Phil LaMarr / Wataru Takagi

"Is time to... double up!"

Twin brothers (if you're wondering how that works for robots, they come from a single spark that split in two) who became the first official flying Autobots after a risky experiment. They are lively and work together.


"You must not sacrifice a piece of the future to bring back the past."

Prowl's former master, Master Yoketron was the head of the Cyber-Ninja Corps. He trained a then-punkish Prowl in the ways of the ninja, humbling him in the process. He planned to make Prowl his successor after his pupil mastered the Processer-over-Matter technique, but he was brutally murdered by Lockdown while Prowl was on an optics quest.


Voiced by: David Kaye / Atsushi Imaruoka

"Any Autobot who won't fight Decepticons is no better than a 'Con himself. We're at war."

An Elite Guard member who answered to Yoketron during the Great War. The loss of his master hit him hard, and he's had trouble finding an outlet for his anger since the end of the War. He's even been known to rough up prisoners when he's in a bad enough mood. He does manage to have a healthy relationship with Flareup, thanks to their mutual love of Stuff Blowing Up.


If your first thought was "Who?", this guy only appeared in the UK comics.

Team Athenia

Rodimus Prime

"You'll have to get past me first, Decepticreeps!"

Hot Rod, later Rodimus, earned the attention of the higher-ups before he even finished boot camp, and he was accepted into Autobot Academy long before any of his campmates. Everyone seems to agree he's destined for big things... if he survives his first encounter with the Decepticons, that is.

  • The Ace: If his magazine bio is to be believed, Rodimus is popular, well-versed in several forms of armed and unarmed combat, and was even nicknamed "The Chosen One" in the Academy (see below).
  • Archer Archetype
  • The Chosen One: Additional material indicates that Rodimus is most likely to become the next Magnus.
  • Determinator: His entire team is defeated while defending a space bridge, and he winds up surrounded by much larger Decepticons. His response?
    "You'll have to get past me first, Decepti-creeps!"
  • Energy Bow
  • Jumping on a Grenade: He did this in boot camp to protect his drill sergeant (Kup) from a stray grenade. It turned out to be a dud, but neither of them had any way of knowing that.
  • You Shall Not Pass / Go Through Me: After the rest of his team has been disabled, he tells Team Chaar they'll have to get past him to get to the space bridge. Oil Slick, unimpressed, takes him out with a vial of cosmic rust.

Hot Shot

Voiced by: Bill Fagerbakke /

"Is it hot in here, or is it just me?"

Team Athenia's own Bumblebee, Hot Shot's speed and recklessness lead to him spending more time in the medbay than any other member, much to Red Alert's exasperation. Why Rodimus thinks he has command potential, she can't imagine.

  • An Arm and a Leg: Strika's bomb damages his leg so severely that Red Alert says she needs to amputate it. She's yanked away before she can finish, and he remains out of the fight.


Might over microchips.

Smaller than Bumblebee, stronger than Bulkhead. Do not cross.

Red Alert

Voiced by: Tara Strong

"I'm gonna have to amputate. Don't worry, Cybertron Service will issue a replacement leg within six to eight solar cycles."

R.A is less of a Combat Medic than Ratchet, but she lived through the height of the Great War and created a cure for Gold Plastic Syndrome along the way. Her teammates appreciate her dedication, although her bedside manner leaves something to be desired.


Voiced by: Corey Burton /

"Hit me with everything you got, sir!"

Ironhide was protoformed in a rural prefecture on one of Cybertron's moons, and he was in the same boot camp squad as Bumblebee, Bulkhead, "Longarm" and Wasp. His pranks can get a little crude, but he's generally a decent "country" bot.

     Main Decepticons 


"With the power of the Allspark, I will reclaim Cybertron for all Decepticon-kind - but not before I lay waste to the miserable world that held me captive for so long."

Megatron likes to think of himself as a freedom fighter, leading his troops to reclaim their home from the Autobots who exiled them after the Great War. This claim is somewhat undermined by his complete lack of concern for anyone not useful to him and his willingness to manhandle his own soldiers to remind them who's in charge... or to field-test weapons of mass destruction on defenceless human cities.

In a surprising turn from the regular "Optimus Prime vs. Megatron" setup of most Transformers series, here Megatron regards Optimus as a minor nuisance, in fact, up until the last episode he never even calls him by name.

  • Affably Evil: Compared to most of his namesakes, this Megatron treats his troops fairly reasonably. note  However, his confrontations with the Autobots will remind you the trope is called affably evil.
  • Aliens of London
  • Authority Equals Asskicking: Even his larger, more powerful subjects bow down to him with little hesitation.
  • Badass: There's a reason why he is the leader of the Decepticons.
  • Big Bad: Takes the throne full-time as of the first season finale.
  • Captured Super-Entity: For most of season one.
  • The Chessmaster: Always has a long-term plan going on, and is known to edit them on the fly when necessary.
    • Pulls a delicious gambit in the final episodes with Shockwave, Starscream and Lugnut as his pawns in the game. He needs a template for his Omega clones, but using himself will likely result in massive Megatron clones that will try to overthrow him and likely will succeed. Starscream is currently in league with him out of no other choice, so Megatron keeps him around to help out despite knowing he will betray him and likely try to become the template himself. So when Shockwave returns to the fold full-time, he begins showering him with praise as his most loyal servant - deliberately to piss off Lugnut, who's loyal to Megs to the point of religious fanaticism and starts making obscenely over-the-top displays of loyalty. When the time comes to make a template, Lugnut stops Starscream from betraying Megatron... and becomes the template for the clones himself. Now Megatron has three massive Lugnut's with Undying Loyalty to him to do his bidding.
  • Chewing the Scenery: While he's usually a lot more sedate than other incarnations of the character, he has his moments. Starscream!!.
    • Bonus points for being voiced by none other than Norio Wakamoto in the Japanese version.
  • Composite Character: Of a few previous incarnations. While based mostly off of his G1 counterpart, his extended planner qualities are from the Beast Wars incarnation (and would have looked somewhat like his Beast Machines counterpart had Season 4 happened). His look prior to Earth and the fact technology was reverse-engineered from him were taken from the first live-action film.
  • Creepy Monotone
  • Dangerously Genre Savvy: He doesn't take Starscream's crap at all. See also The Chessmaster.
  • Dark Is Evil: He is colored black and metallic grey.
  • Dark Lord on Life Support
  • Deadpan Snarker
  • The Dreaded
  • Evil Brit: Speaks with a slight accent.
  • Evil Sounds Deep: Corey Burton took inspiration from Tim Curry and Christopher Lee.
  • False Friend: Paints himself as a friend of the Autobots and ally of humanity during his time trapped in Professor Sumdac's lab.
  • Large And In Charge: Averted. He's huge, but he's got soldiers bigger than him like Lugnut and Blackout.
  • Lightning Bruiser: Has incredible strength and speed.
  • Losing Your Head: Lost it when he crash-landed on Earth.
  • Manipulative Bastard: Can play people like a fiddle, including Professor Sumac, the Constructicons, his troops...
  • Oracular Head: Season 1, following the destruction of his body in the pilot. He gets a new one in the season finale.
  • Orcus on His Throne: During season 2, his space bridge project keeps him too busy to go out.
  • Psychotic Smirk: Does this frequently.
  • Sealed Evil in a Can: For most of season 1.
  • Shoulders of Doom: In his Cybertronian body; his Earth form replaced them with Vertical Mecha Fins.
  • Shrouded in Myth: At least by the time of the present day, if Bumblebee's crazy stories in the pilot about him are any suggestion.
  • The Stoic
  • Villainous Breakdown: "Destroy everything that's not me!"
  • Villainous Cheekbones
  • Weapon of Choice
  • Wicked Cultured: He's the vicious leader of the Decepticons, but he's also an oil connoisseur, even brewing his own blends!
  • Worthy Opponent: He's alarmed when he believes Ultra Magnus has come to fight him in the Grand Finale. By the end of the episode, he regards Optimus Prime as this after he's stood in the way of his plans for far too long and too stubbornly.
    Megatron: If I cannot save my clones, then at least I'll have the satisfaction of destroying you, Optimus Prime!
    Optimus Prime: So you can remember my name.


Voiced by: Tom Kenny / Jin Yamanoi
"YES! Right then, solemn face, solemn face..."

Starscream is an actual threat to the Autobots this time around, capable of flooring even Ultra Magnus with a close enough shot, but he has about as much chance of winning a fair fight with Megatron as his G1 self. Of course, being Starscream, a fair fight is generally the last thing on his mind.


Voiced by: David Kaye

Lugnut: Stasis lock itself could not deter me from your grand and glorious plan, o wise and noble Megatron!
Megatron: Just... go.

A powerful Decepticon and former gladiator, Lugnut is extremely and utterly devoted to Megatron. During the Grand Finale, he becomes the imprint for Megatron's Omega Sentinel clones, transforming them into a trio of Lugnut Supremes.

  • Battle Butler
  • The Brute: One of two.
  • Canon Emigrant: Has gotten a toy in the 2010 Transformers toyline, and later made a few appearances in the IDW G1 comics.
  • Comically Serious: He's the straight man to Blitzwing (which isn't saying much), but a few moments shine.
    (after finding Megatron)Lugnut: Oh master! I am not worthy! I am not worthy! *beat* What happened to your body??
    Megatron: Long story.
  • Cyber Cyclops: He seems this way, but those things on the side of his head are also eyes, so he actually has five.
  • Dumb Muscle
  • The Dragon: Takes over this position after Starscream's treachery is discovered.
  • Evil Sounds Deep
  • Foil: Serves as a foil of sorts to several characters.
    • Starscream: Starscream's legendary treachery makes a big contrast to Lugnut's Undying Loyalty.
    • Bulkhead: They're both the biggest, strongest and least intelligent members of their respective teams, but where Bulkhead is a Gentle Giant with Hidden Depths, Lugnut is a destructive brute with no depths seen.
    • Shockwave: They're both devoted to Megatron (and have been known to brawl over who's the most loyal) but while Lugnut is dumb as a rock, Shockwave is loyal but smart.
    • Which is exactly why Megatron does not consider it a setback for him to be the template for the custom Supremes.
  • Ground Punch: Lugnut often uses his Punch Of Kill Everything in this manner, leaving enormous craters and devastating any Autobots (and unfortunate Decepticons) who happen to be in nearby.
    • This can be turned against him, however. The trigger on the POKE is a Big Red Button on top that's highly sensitive. In "Megatron Rising, Part 2", Lugnut tries using the POKE against Bulkhead, but the Autobot is able to use his flail to push the button, sending Lugnut flying. In "Garbage In, Garbage Out", Wreck-Gar misinterprets Lugnut's threatening to Ratchet as the universal greeting...which in this continuity, ends in a high five.
  • Hidden Depths: He displays some considerably competent leadership abilities during "Decepticon Air", and several other times he's shown to be rather cunning.
  • Honor Before Reason: "I will not hide! I will stand proudly and shout Megatron's name to the HEAVENS!"
  • Implacable Man
  • Large Ham: Especially when he starts praising "The great and GLORIOUS Megatron!".
  • Lightning Bruiser: Suprisingly fast as well as incredibly strong.
  • Minion Shipping: With Strika, although this is only mentioned in secondary material.
  • Stuff Blowing Up: He has perfected the art of making things explode. Behold! The P.O.K.E!
  • Sycophantic Servant: To the point where even the Grand and GLORIOUS Megatron gets tired of the praise.
  • Those Two Bad Guys: With Blitzwing. They hang out even when they aren't fighting.
  • Undying Loyalty: Taken to the extreme. He can practically make religious sermons about his great and GLORIOUS leader.

(Icy): But my orders are to retrieve the Constructicons...
(Random): Oooh, but I like iron filings! Especially sprinkled on top of servo salad!

At first glance, Blitzwing seems to be a stoic, no-nonsense Decepticon. However, he is a master Mood-Swinger, able to change from stoic to anger to insanity depending on his mood.


"It'll be a long time before I ever trust another Autobot. Especially you, Optimus."

Formerly Elita-1 - Optimus and Sentinel's best friend - Blackarachnia joined up with the Decepticons to find a cure for her cursed techno-organic form. Though she uses her spider abilities to her advantage, she can't stand her hideous appearance and is desperate for a cure. She tends to use her beauty to seduce those around her to get what she wants - just... don't look under the helmet. She's currently stuck in an unknown jungle with Waspinator.

  • Advertised Extra: Despite her importance to Optimus and Sentinel's backstory, and receiving top billing, the Dinobots, who are recurring characters at best, make far more appearances than her.
  • Anti-Villain
  • Arachnid Appearance and Attire
  • Building Swing
  • Combat Stilettos: Oddly, she only has these after becoming part-organic.
  • Composite Character: She's a combination of the original Blackarachnia from Beast Wars and Elita One from Transformers Generation 1.
  • Corrupt the Cutie: Her transformation from Elita-1 after being mistakenly Left for Dead with the giant spiders. Also doubling as her Start of Darkness.
  • Dark Action Girl
  • Dark Chick
  • Distracted by the Sexy: She plays it up for the male bots.
  • Expy: She's like a less psychotic version of Demona.
  • Fallen Hero
  • Fantastic Racism: Or a victim of such. She left the Autobots rather than risk being strapped to a lab table.
    • Also, a self-inflicted example: she can't stand being part-organic.
  • Faux Action Girl: Her evil schemes very often ended with her needing to be rescued as well as, or rather than, her victims.
  • Femme Fatale
  • Giant Spider: And unlike her BW version, her spider mode is the same size as the ones she gained it from.
  • I Am a Monster: Thanks to a combination of Cybertronian anti-organic prejudice, the trauma of her transformation and the fact she is kind of disfigured looking, she's really, really not happy about her present state.
  • Mad Scientist: Not only regarding techno-organics; The AllSpark Almanac states that she rebuilt Blitzwing into a triple-changer sometime after the Great War.
  • Power Copying: Her original special power was the ability to download and temporarily replicate the powers of other transformers. Trying to use this on Energon-infused alien spiders turned her into what she is now. She still has the power, though she doesn't use it very often.
  • Never My Fault: Has elements of this in her attitude; Optimus may have been the one to assume she was dead and leave her behind, but it was (presumably) Sentinel's idea to go to Aracha 7 in the first place, and she was willing to go along in the first place — she and Sentinel convinced Optimus to come, not the other way around.
  • Sealed Evil in a Can: "Black Friday" reveals she washed up on the shore of Dinobot Island after the Season 1 finale. Because of her organic nature, she can't simply swim back to the mainland. Prometheus Black's laboratory, however, gives her a reason to not want to leave.

Shockwave/Longarm Prime

"Rise, Shockwave: my most loyal servant!"

Shockwave is a Decepticon spy taking on the form of Autobot Longarm Prime. When rumors of a spy were floating around Autoboot camp, Longarm secretly plotted for Wasp to take the fall, succeeding admirably. He later becomes leader of Cybertronian Intelligence and uses his position to spy for the Decepticons. He gloatingly reveals himself to Bumblebee in the season two finale, only for Megatron's space-bridge plan to fail, leaving him terrified of discovery. Shockwave eventually attacks and severely damages Ultra Magnus, stealing his hammer in the process.

  • BFG
  • Creepy Monotone: As Shockwave.
  • Cyber Cyclops: He even quotes HAL 9000 in season 3.
  • Deep Cover Agent
  • Devil in Plain Sight: Spent several decades, if not longer, worming his way up the Autobot chain of command, and no-one was the wiser.
  • Drop the Hammer: He steals the Magnus Hammer after almost killing its owner. Ratchet retrieves it in "This Is Why I Hate Machines".
  • Evil Brit: Corey Burton reprises his David Warner impersonation.
  • Eviler Color Switch: He celebrates his reunion with Megatron by switching to his G1 colours.
  • Expy: With his grey and purple coloring, antler-like comm antennae, extensible arms & sinister mono-eye, he's a dead ringer for Perfect Zeong.
  • False Friend: to Bumblebee during their academy days.
  • Have You Told Anyone Else?: Blurr hadn't and was dead in a matter of minutes.
    • Not dead, just cubed. In the animated version, we don't know if he lived or died; he was alive after being cubed, but supposedly tossed in the incinerator, but in the comics he lived for certain.
  • Hero Killer: He nearly killed Blurr, but also had the series continued, his attack on Ultra Magnus would've proven fatal. He also murdered Highbrow for the job of Head of Cybertron Intelligence in the past.
  • In the Hood: His head's shape and one eye glowing on a dark panel visually evokes a face hidden under a hood.
  • Knight of Cerebus: Unlike many other Decepticons in the show, he has no humorous quirks to balance out how frightening and serious he is.
  • The Mole
  • Nice Job Fixing It, Villain: Shockwave ultimately proves to be his own undoing by blaming Wasp for the space bridge attacks.
  • Rubber Man: His shapeshifting ability allows him to extend his limbs.
  • Secret Identity
  • Sudden Name Change: He was actually given the name "Chugway" in the subtitles for the episode "Autoboot Camp."
  • Tank Goodness: As Shockwave, he can turn into a tank.
  • Tinman Typist
  • Villainous Breakdown: Approaches this by the time people have found him out.
  • Vocal Evolution: Burton's take on Shockwave is more whispery and soft spoken compared to the G1 cartoon, where he bordered on No Indoor Voice.
  • Voluntary Shapeshifting: Moreso than the other Transformers.
  • Worthy Opponent: Admits this much to Ratchet during This Is Why I Hate Machines.

     Other Decepticons 


"I am Soundwave. I am Decepticon. The revolution begins now."

Soundwave was another of Megatron's attempts to regain a body during his tenure as a talking head. He presented the plans to Isaac as a walking music player he could give Sari for her birthday, anticipating that Sari would use the Key on it and programming Soundwave to upgrade into a specific form. What he didn't expect was that Soundwave would become sentient, although he was only too willing to take up the Decepticon emblem.

Scrapper and Mixmaster

Voiced by: Jeff Bennett (Mixmaster) and Tom Kenny (Scrapper) /

Mix: Who puts the "crude" in "crude oil"?
Scrap: Mixmaster and Scrapper, that's who!

Two 'bots brought to life by Allspark fragments, Mixmaster and Scrapper (known as the Constructicons) want two things: hot cars and oil. Though Bulkhead tries his best to befriend them, their minds drift right back into trouble just searching for those two things. They later join the Decepticon side by building Megatron a space bridge in exchange for oil. They're later caught in a massive explosion alongside their boss, Dirt Boss, but only Scrapper is currently shown to be alive. The whereabouts of the other two are unknown. During their separation, Scrapper ended up on Dinobot Island, befriended Snarl, and briefly joined the "Subtitute Autobots", with poor effects.

Dirt Boss

Voiced by: John Mariano

"What're you cogs lookin' at? You wanna piece 'a me? Try it and you'll be goin' to the scrapyard in a crankin' box!"
His first words

Mixmaster and Scrapper's self-appointed boss, also a product of an Allspark fragment (combined with a damaged Headmaster unit and a forklift). He is a no-nonsense, strict and nasty piece of work who keeps the Constructicons busy.

Lockdown (technically unaffiliated)

Voiced by: Lance Henriksen
"I know you... EMP generator, right? I'm not good with names and faces, but I never forget a trophy."

A neutral bounty hunter, Lockdown caters to whoever pays him the most (usually the Decepitcons). He is a mish-mash of different mods and body-parts and a hoarder of trophies from various 'bots he has stripped and robbed over the years. He was also a former student of Yoketron before he realized he didn't like all that spiritual crud. As his first act as a bounty hunter, Lockdown killed him and took the protoforms Yoketron was tasked to guard. He has a history with Ratchet and a rivalry with Prowl, in whom he sees a Worthy Opponent and kindred spirit.

  • All There in the Manual: The Allspark Almanac confirms that Lockdown utilizes an Autobot shell, which adds further evidence to the possibility that Lockdown was actually an Autobot before his current form of business.
  • Arch-Enemy: To Prowl and especially Ratchet, due to having personal history with both.
  • The Assimilator: He takes trophies from his victims and incorporates whatever bits he likes or needs into himself. The rest go on the wall.
  • Badass Baritone
  • Badass in a Nice Suit: His design suggests a skull-like head on top of an undertaker's tuxedo.
  • Bounty Hunter
  • Canon Emigrant: Has shown up in the Revenge of the Fallen toyline, IDW's G1 comic continuity, and the fourth live action Michael Bay film.
  • Chainsaw Good
  • Collector of the Strange / Creepy Souvenir: He states outright that collecting trophies from his victims is his favorite part of the hunt.
  • Cool Car
  • Deceptive Disciple: He used to be an Autobot in the Cyber-Ninja Corps, but was expelled after 'bringing shame to it' somehow. He later killed Yoketron and stole the Corps' cache of protoforms to sell to the 'Cons.
  • Evil Sounds Deep
  • Fashionable Asymmetry: to represent that he has parts from former preys, each of his limbs has a different color, with a yellow right arm, a purple left arm, a metallic left leg with purple features, and his right leg is the only one that actually fits with the black and green pattern of his torso. The first figure of the character is the only one that keeps him that way (even if both arms are the same color when removing the hook hand), while later recolors and the movie versions miss the point by keeping him in more uniform color patterns, with the hook as the only asymmetrical element.
  • Faux Affably Evil: One of the scarier parts about him.
  • Hook Hand
  • Knight of Cerebus: Has nothing comedic about him and is by far the most outright evil character to appear.
  • Morph Weapon: His chainsaw.
  • Ninja Pirate Zombie Robot: His hook hand effectively makes him a robot pirate; early designs even had an eyepatch. What's more, he has a death motif in his undertaker look and skull-like head, and was once a ninja pupil of Yoketron - meaning he may be one of very few literal expressions of the trope depending on how you count it.
  • Psycho for Hire
  • Rocket Punch: He used one in his first appearance; when Ratchet destroyed it, he replaced it with a Hook Hand.
  • Shoulders of Doom
  • Spikes of Villainy
  • The Unfettered
  • Whole Costume Reference: His color scheme is very reminiscent of Boba Fett, who the creators said was part of the inspiration for Lockdown.
  • Working for a Body Upgrade: Between taking parts from those he hunts and preferring to be paid in upgrades, Lockdown has a double dose of this.

Swindle (technically a Decepticon)

Voiced by: Fred Willard
"Hmmm, maybe I should help them - or maybe I should just help myself!"

The Decepticon equivalent of a used car salesman. Swindle is a charming individual who sells weaponry and whatever business he can get his hands on - as long as he can make a profit, it doesn't matter! Voiced, fittingly enough, by the CEO of Buy & Large.

Starscream Clones

Voiced by: Tom Kenny (all males), Tara Strong (Slipstream)
"Ah, never before have I seen a more impressive group of lethal fighting machines... and pretty good-looking if I do say so myself."

Stolen protoforms + Starscream personality mod suits + Allspark slivers from the chunk keeping the real Starscream online = trouble (and hilarity). While they have the same weapons and speed as the original, they each represent an exaggerated (er, even more so) aspect of his personality, which makes some of them a lot less effective than they could be. Two of them show up in A Fistful of Energon, but are revealed to be walking bombs. Starscream builds five more during the season two finale for his assault on Megatron.

The second Almanac adds another two - Dirge (toy-only) and Thrust (who never showed up at all), created by Swindle to act as bodyguards. All in all, not one of his best ideas. You want them? He can let them go cheap!

  • Affably Evil: Sunstorm
  • All There in the Manual/Mythology Gag: None of them are ever named in the cartoon, although if you're a fan of the original series, you can guess all but one or two based on color scheme.
  • Bad Liar: Ramjet, who literally can't say anything except outright contradictions.
    "Oh, I would never do that."
  • Cannot Tell a Lie: Inverted by Ramjet.
  • Dangerously Genre Savvy: Slipstream when handling allegiances or taking down Omega Supreme. Sunstorm also displays some creative thinking, once cutting out his tracking signal to lure Autobots off his tail.
  • Dark Action Girl: Slipstream.
  • Dirty Coward: Skywarp.
  • Green-Eyed Monster: Thrust, the clone created late in the game according to the Allspark Almanac 2, is the embodiment of Starscream's intense envy. He pals around with Dirge, which is appropriate since their quirks more or less compliment one another.
  • Ineffectual Sympathetic Villain: Poor Skywarp.
  • Informed Ability: Their bios claim they have various unique abilities based on their G1 counterparts (teleportation for Skywarp, energy absorption for Sunstorm, etc). None of these ever had a chance to appear in the cartoon.
  • Literal Split Personality
  • Me's a Crowd
  • Nice Hat: Swindle gives Sunstorm and Ramjet helmets to help him differentiate them. Doubles as a Mythology Gag.
  • Not-So-Harmless Villain: Most have comedic points, but they can be quite dangerous. Sunstorm especially was effective in the 2nd Season Finale.
  • Palette Swap
  • Professional Butt-Kisser: Sunstorm.
  • Riddle for the Ages: According to Word Of God, the aspect of Starscream that Slipstream represents is one of these.
  • Small Name, Big Ego: Thundercracker, who takes this trope Up to Eleven.
  • The Smurfette Principle: Slipstream.
  • Toyless Toyline Character: Slipstream. Inverted by Dirge, who does have a toy, but never appeared on the show. Thrust didn't get either and is only known to exist through supplementary material. No wonder he's envious.
    • Slipstream did eventually get a the Transformers Legends line. This is a confusing example as while the tie in comic does say she's the same character having jumped dimensions (with her head specifically made to look animated style), it's a completely different toyline altogether.
  • Villainous Glutton: Dirge, the one toy-only clone, represents Starscream's insatiable greed.
  • Yes-Man: Sunstorm.
  • You Do Not Want To Know: What part of Starscream's personality does Slipstream represent, anyway? Best just not to ask. Word Of God isn't being entirely serious about this.

Team Chaar

"Oooh, the Autobot Elite Guard. This should be fun."

A big, hulking fembot who is just as loyal to Megatron as Lugnut is. Makes sense, too - they're married.


Are you going to eat that?

A Decepticon who can suck in Autobots with his tentacles and either "eat them" or spit them out, covered in explosive slime. He's kind of horrible.


Voiced By: Bumper Robinson

"Lights out."

An extremely large Decepticon - in fact, until the advent of Project: Omega, he was the single largest Cybertronian ever protoformed. He fought during the Great War and was essentially a one-man army.

  • Badass: He was on the Decepticon's answer to The Wreckers, and he was personally involved in the destruction of at least four Omega Sentinels.
  • The Brute
  • Canon Immigrant: Based heavily on his live-action counterpart. His transformation sound is deeper and more metallic than the other characters, very much like the movies' sound.
  • Dumb Muscle: He's the biggest, most heavily-armed Decepticon alive, but isn't much help without supervision.
  • EMP: Also works in reverse.
  • Hero Killer: He's one of the biggest and most feared Decepticons that was ever created.
  • One-Man Army: His custom Decepticon sigil means he is the Decepticon Heavy Brigade: the rest of his unit died fighting Zeta Supreme. Blackout went on to kill three other Omega Sentinels during the War.
  • Percussive Maintenance: He can use his stomp to knock out electronics and then reactivate them by doing it again.
  • Villain Decay: Only in The Cool comic. Jetfire and Jetstorm are able to easily avoid his attacks because of their speed, and then they turn into their combined mode to take him down. In the War, Blackout killed robots the size of Omega Supreme, and took down opponents both larger and smaller than him (like Rodimus).

Oil Slick

Voiced By: Phil LaMarr

Rodimus Prime: You'll have to get past me first, Decepticreeps!
Oil Slick: You say that like it's a difficult thing, Autobot.

An expert chemist, Oil Slick invented the deadly weapon "cosmic rust", is a master of vehicle-to-vehicle combat and claims to have trained in Circuit-Su with an Autobot motorcycle, although he's not giving out any details.

  • Canon Immigrant: He started as an unrelated sketch, got produced as a toy, made an appearance in a side-comic, and was introduced in the third season.
  • Cool Bike: Based on the 'Dodge Tomahawk' concept motorcycle, with a goat skull at the front.
  • Epic Flail
  • Evil Genius
  • Lean and Mean
  • Mad Scientist
  • Ninja Pirate Robot Zombie: A ninja robot chemist, though the 'ninja' part is only mentioned in secondary material: he apparently studied Circuit-Su with Prowl. How that could happen is unclear, but there is a big gap in Prowl's past...
  • Plague Master: His dome-helmet protects him from his own chemical weapons and poisons.
  • Spikes of Villainy: More notably in his Cybertronian mode, where he's practically covered in them.
  • We Have Reserves: In the comic where he was introduced, he tested his "Cosmic Rust" chemical in the middle of a battle, taking out soldiers from both sides.


Compassion is the Autobots' downfall.

The stoic Cyclonus appeared in the skies of New Kaon in a storm of light and tachyons some time after the Great War ended, and has remained a complete mystery ever since. He has sworn loyalty to Megatron, but even that seems somehow abstract - and just who is this "Galvatron" he keeps talking about?


Sari Sumdac

Voiced by: Tara Strong

"Listen up, oil brain! My family needs your help, and you are going to help, get me?"

The young daughter of Issac Sumdac, Sari is what anyone her age is; precocious and spunky. She is immediately drawn to the Autobots (especially Bumblebee) and serves as their representative and educator of Planet Earth. When she comes in contact with the Allspark, Sari's access key turned into a literal key that can fix damaged Autobots and allow her to manipulate nearly any type of machinery.

We later find out why the Allspark chose her: Sari is really a Cybertronian protoform turned half-human, half-robot after Issac accidentally input his DNA into said protoform. Naturally, she doesn't take this well at first. Sari then gets a system upgrade that ages her up to a sixteen-year-old to make her more powerful. She continuously uses her skills in battle and later helps out during the final battle.

Professor Isaac Sumdac

Voiced by: Tom Kenny /

Isaac Sumdac is the head of Sumdac Systems, the business at the heart of 22nd century Detroit, which relies heavily on his "tireless mechanical helpers". He managed to create these elusive robots by reverse-engineering technology from Megatron, whose head he discovered as a teenager. When Megatron reactivated, he convinced Isaac, who had no idea he was talking to a Decepticon, to keep him a secret from the Autobots. When they found out, they weren't pleased. Megatron later kidnapped Isaac to work on his space bridge, leaving Sari to take over Sumdac Systems briefly before Porter C. Powell kicked her out. He is eventually freed - just in time for Sari to learn the truth about herself.

He is the classic absent-minded professor, forgetting to eat in order to get his robotics in tune. He is well-meaning despite it and remains a loving father to Sari.

Captain Carmine Fanzone

Voiced by: Jeff Bennett

"A technophobe is someone who fears technology." *smashes a phone* "Does ''this''' look like fear to you?!"

The loud captain of the Detroit Police (and master of yelling into megaphones), Fanzone dislike one thing and one thing only: machines. This hits him over the head when Detroit's heroes turns out to be giant robots. Still, for the sake of peace, he tries and learns to live with it, relying on them when he has to. Irony of irony, Fanzone is also the first person to visit Cybertron and most of the residences there fear him because of his Organic stature.

Prometheus Black/Meltdown

"Are you ready to feel the burn?"

An expert biologist, Prometheus Black used his talents to manufacture "biochemical makeovers", but lost his funding when a PR stunt involving Bumblebee and Colossus Rhodes went badly wrong. Angry that he has to compete with the likes of Sumdac and his machinery (which he hates), Prometheus vows vengeance. He gets it when he's accidentally turned into essentially walking acid. He's one of the few who can melt Cybertronians without even trying, making him a deadly foe.

  • Becoming the Mask:
    Fanzone: Prometheus Black?!
    Meltdown: The name is Meltdown!
  • Beware the Silly Ones: His outfits and Disco Dan-nature aside, Meltdown is the only human villain who poses a real threat to the Autobots one-on-one and his experiments are about as depraved as anything the Decepticons do.
  • Body Horror: Himself obviously. But those two monsters working for him in two episodes? One used to be his lawyer.
  • Cool Shades
  • Disco Dan
  • Fantastic Racism: Against machines, to a far more vicious extent than Captain Fanzone.
  • Freak Lab Accident: Autobot fluid + his special steroids = ouch.
  • Hollywood Acid: Outside of some specific things that can apparently resist acid, he can melt through anything he touches, including the Autobots.
  • I'm Melting: His own genetic modifier liquefies him in Black Friday. The end of the episode reveals he's still alive, but he never shows up again.
  • Mad Scientist
  • Pick on Someone Your Own Size: He blames the Sumdacs for his company's failure and kidnaps Sari when he decides he needs a child for an experiment.
  • Playing with Syringes
  • Sesquipedalian Smith
  • Squishy Wizard: His acid, which he can also fire from his hands, will burn through anything, but if he's helpless is faced by something that's resistant to it, notably shown when Fanzone grabbed one of his protective suits and overpowered him.
  • Unknown Rival: Sumdac knew about him and his company, but he had no idea how much Prometheus outright hated him.

Porter C. Powell

Voiced by: Bumper Robinson
"Oh, I don't think I'm in charge, young lady: I know it."

A shrewd business man who uses every dirty trick in the book to gain power and money. He works in Sumdac Systems, but briefly takes over it when Isaac "mysteriously disappears".

Henry Masterson/Headmaster

Voiced by: Alexander Polinsky
"Get ready for T.O.T.: Total Ownage Time!"

A young scientist who has created a robotic head that can take over any other living robots' body (he's kind of a control freak that way), controlling them under his will. Headmaster speaks in computer leet speak (retro leet speak, considering this is the 22nd century).

A. A. Archer/Angry Archer

Voiced By: Jeff Bennett

"An Autobot! Verily the arrows of outrageous misfortune seek to pierce me to the quick - exeunt!"

A Robin Hood-ish figure who steals from the rich and gives to the poor, namely himself. The Angry Archer also has a habit of speaking in quasi-Shakespearean diction.
