"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.
Oil Slick: One of Optimus' less-used tricks has him spraying "negative friction lubricant".
Reassigned to Antarctica: He was on the fast track to the Elite Guard as a cadet, maybe even future Magnus. That was derailed after Sentinel talked him into visiting a planet with a crashed Decepticon warship, resulting in the loss of Elita-1. The reassignment actually could have been worse, though; he got his rank and position on the charity of Ultra Magnus.
Unknown Rival: Megatron knows he exists, but spends almost the entire series calling him "Autobot". Megatron calling him "Optimus Prime" in the finale is when he finally acknowledges Optimus as his greatest enemy.
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.
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.
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.
"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.
Alien Arts Are Appreciated: Bulkhead doesn't know what art is, but when Sari introduces him to the concept, he takes to it immediately and has a gallery show at the end of the episode. He's painting again in the season 2 finale.
"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.
Jerk with a Heart of Gold: He may be a cranky old bot, but he's genuinely concerned about protecting the Earth from Megatron and the Decepticons, which he admits in a rather tearful confession to Sari.
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.
Distress Ball: In episode 2, he tells Optimus Prime that there's only one person he trusts. Himself. He promptly gets sucked into a nanite monster and almost killed were it not for his teammates. In fact, despite him being the best fighter of the team, Prowl catches the Distress Ball quite a few times in the series, usually after trying to do something alone. Maybe it's trying to send him a message?
Draft Dodging: Tried to avoid being drafted into the war, but ended up being apprehended by Warpath and taken to Yoketron's Dojo.
"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.
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.
"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.
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.
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).
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.
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.
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.
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.
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.
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.
Line-of-Sight Name: Mixed together from stuff people were yelling at him. "They call me Angry Archer." "They call me "Worthless-wreck-walking-pile-of-garbage"." "Oh, really? Bit of a mouthful..."
Red Eyes, Take Warning: His eyes turn red for a brief time in "Garbage In, Garbage Out" when he declares that he's going to destroy the city, a nod to The Movie and the original Wreck-Gar's toy commercial.
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.
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.
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."
"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!
Adaptational Badass: This incarnation of Wasp/Waspinator is much, much scarier and more villainous than the Waspinator in Beast Wars, who was mostly the Chew Toy of the series, being blown apart frequently.
Shout-Out: There are many similarities between this version of Wasp and the BW incarnation. It could even be said that his misfortune of being thrown out of the academy and into the stockades referenced the original incarnation's misfortune of being The Chew Toy.
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.
"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.
"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).
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.
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.
"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.
Caped Mecha: Her labcoat, although it's actually part of her vehicle-mode.
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.
Dub Name Change: In Japan, Bulkhead is now called "Ironhide", so this Ironhide is now "Armorhide".
Jerk Jock: With Wasp as an Autobot cadet. Unlike Wasp (or Sentinel), he got better.
"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.
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.
Adaptational Badass: He's not as competent a leader as he thinks he is, but he's still a powerful fighter.
Back from the Dead: Megatron slags him in the last episode of season one, but an Allspark fragment lands on his head a few episodes into season two and keeps bringing him back to life no matter what happens to him. At least, until Prowl and Jazz removed it.
Butt Monkey: From season 2 onward, he becomes a Butt Monkey in this series. It starts with the infamous "Starscream Death Montage" with Megatron killing him over and over again (with the allspark fragment on his head being the only thing keeping him alive). All of his plans always fail and in the finale in which may be his Crowning Moment of Butt Monkery, his clones (with one heavily implied to represent his self-loathing) betray him for Megatron. He spends the majority of season three as a disembodied head trapped with Megatron aboard Omega Supreme, and just when he fnally gets a new body, Megatron blasts him (He recovers). And in the finale, The allspark fragment that was keeping him alive is pulled out, thus killing him. And if you count the comic adaptation, he gets humiliated and blackmailed by Professor Princess. One can't help but feel a bit sorry for him.
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.
Early Episode Weirdness : Blitzwing's design changes a bit through the series. Early Blitzwing had spikes on his shoulders and didn't have the large have the large, square weapon pack on his back (His Weapons just came out from his back). His Wings were also smaller.
Personality Powers: Icy and Hothead are ice/jet and fire/tank respectively, while his Random persona can use both. His big weakness is that it's involuntary - if you can get him to, say, switch from Icy to Hothead when he's in jet mode, he'll have no choice but to turn into a tank while in midair.
"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.
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.
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 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.
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.
"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.
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.
"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.
"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.
The Assimilator: He takes trophies from his victims and incorporates whatever bits he likes or needs into himself. The rest go on the wall.
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.
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.
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.
"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.
Punch Clock Villain: He's not very malicious, unless his business ventures are threatened. His joining up with Lugnut and the Decepticons in "Decepticon Air" was only to get some payment from Megatron, and he outright abandons them.
Chest Blaster:Something resembling a futuristic gatling gun pops out of his chest. He's lost most of these weapons by his second appearance - possibly the police or the Elite Guard removed them - but makes up for it using his personal storage dimension.
"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 someof 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!
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.
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.
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.
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.
Villainous Glutton: Dirge, the one toy-only clone, represents Starscream's insatiable greed.
Grievous Harm with a Body: One of his major battle tactics is to grab an opponent with his tongues, swallow them, coat them in explosive slime, and fire them at their other opponents as a living projectile.
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).
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.
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?
"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.
Batman Can Breathe in Space: Post-upgrade, switching to her robot alt-mode is sufficient to protect her from the vacuum of space. Notable because Blackarachina, also a techno-organic, threw a fit about her own organic parts not being able to survive underwater long enough to reach the Autobots' sunken spaceship. Then again, maybe Sari's version is just better given its source.
Blade Below the Shoulder: Her upgrade included pop-out arm blades that can do some serious damage, as poor Bumblebee found out the hard way. Ratchet apparently had to shut most of her weapons down after she nearly overloaded.
Robot Girl: Before the upgrade, she could eat, sleep, cry and catch colds, but just happened to have metal under her skin and hidden palm blasters. Post-upgrade, she's still at least partly human, but has a lot more tricks.
Undead Tax Exemption: Averted. When she takes over her father's company in season 2, she's quickly ousted because there are no documents proving she legally exists. This also serves to explain why she was so sheltered. It's not that he didn't want to send her to regular schools, he simply couldn't.
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.
Absent-Minded Professor: He runs his own company, but sometimes forgets to feed himself and... isn't that great at judging how trustworthy someone is.
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.
Running Gag: His car is regularly crushed and was once blown up by Blitzwing, but it keeps coming back, complete with its characteristic rust. Is it possible for a non-sentient object to be The Chew Toy?
Tuckerization: According to Marty Isenberg, he's named after Detroit native Carmen Fanzone, a former neighbour of his who used to play for the Chicago Cubs.
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.
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.
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.

"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".
Ascended Extra: He originally appeared as one of Prometheus Black's investors in "Total Meltdown." He wasn't going to appear afterwards, but the crew were taken by his design and wanted to see more of him.
Laser-Guided Karma/Break the Haughty: After being a Karma Houdini throughout Season 2, "Black Friday" saw him tormented by Grimlock, lose a valuable piece of equipment and Fanzone threatening to arrest him for "disturbing the peace." Later in Season 3's "Human Error," he sells Soundwave toys based on Sumdac's original design. After the real Soundwave's villainous actions, however, Powell is financially ruined by the returns/refunds.
What, Exactly, Is His Job?: He's... he's definitely a businessman. Yeah. But he's been seen as the CEO of a car company, breaking deals with gene-splicers, usurping a robotics company from an 8-year-old girl, and selling knockoffs of the original Soundwave toy. His main area of expertise remains a mystery.

"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).
Beware the Silly Ones: This guy might be an idiot, but outside of Meltdown, his the only human that manages to actually a pose a danger to the Autobots without any help from the Decepticons.
A family of in-jokes, the Witwickys are generally somewhere in the background, although they briefly join the main plot in "Garbage In, Garbage Out", during which Carly is giving birth and is unlucky enough to be picked up by Ratchet in ambulance mode. Spike and/or Carly work for Isaac, since Daniel is one of the few kids at Sari's birthday party.
"I ain't nobody's errand boy... unless the price is right."
Nino was once a common thief until he was given a speed suit secretly by Megatron, causing him to create wanton havoc until the suit aged him up. He is eventually restored to his youth by Slo-Mo, whom he falls for.
"I'm the leader of this syndicate. The head honcho, the big cheese, see?"
Speaking in 1930s moxie speak, Slo-Mo is a woman with the ability to slow down time, thanks to a watch embedded with an Allspark fragment. She rounds up all the other human villains and forms the S.U.V (Society of Ultimate Villainy). She also has a thing for Nanosec.
