    Sari Sumdac (SPOILER!) 

Sari Sumdac
Click  to see her after her upgrade.
Voiced by: Tara Strong / Satomi Akesaka

"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.

  • Action Girl: She's as useful in combat as the Autobots.
  • Alliterative Name: Her first and last names both begin with S.
  • Ambiguous Situation:
    • It is unknown how her protoform got into Sumdac Towers. The "The Trial of Megatron" reading reveals that she isn't a protoform and no one is sure of what she is. Not even Word of God came up with an explanation on what she was, although they also state that this would have been answered by the Season 5 finale.
    • According to Vector Prime in All There in the Manual, he says that something feels familiar about her.
  • Badass Adorable: She's a very cute child and is also a useful ally to the Autobots.
  • 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 activated a pair of pop-out arm tonfa 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.
  • But Not Too Black: She is suppossed to be Indian, but has distinctly un-Indian facial features(possibly due to the art style), has red hair, is voiced by Tara Strong(who is white), and lacks her father's Hindi accent. The fact she's a Transformer herself somewhat explains the discrepancy, but it then raises a whole new question of how Sari's protoform scanned Isaac and to what extent.
  • Curtains Match the Window: Until her upgrade, when she gets Autobot-style eyes.
  • Dark-Skinned Redhead: Her hair is red and her skin is dark brown. This may be a nod to the unnatural "neon" colors often used for beast modes in the Beast Era.
  • Deadpan Snarker: Oftentimes is one, especially whenever Bumblebee (or any of the other Autobots, really) regard humans as weird. Significantly more so in Season 3 due to her adopting a Let's Get Dangerous! attitude.
  • Drop the Hammer: The Almanac II even calls it a Hyperspace Mallet!
  • Expressive Hair: Her pigtails sometimes droop down or stand on end to reflect her emotions.
  • Fiery Redhead: She's a pretty passionate young girl.
  • Friendless Background: Because she's been homeschooled her whole life, she doesn't have any friends.
  • Genki Girl: She's very chipper and energetic.
  • Girlish Pigtails: She has pigtails. Even in her robot mode.
  • Half-Human Hybrid: She is eventually revealed to be half-Cybertronian and born from a protoform copying her father's DNA.
  • Has Two Mommies: Primus only knows how many actual daddies she has. Isaac Sumdac plus however many it takes to make a protoform.
  • I Got Bigger: Sari's first transformation into her robot mode significantly increased her height. Compared to the kid she was before, Sari is actually pretty lanky in Season 3, outgrowing her father. It's possible that her new height reaches Statuesque Stunner levels, but the artstyle of the show doesn't really allow an ideal comparison and there haven't been any official height measurements either, so that makes that rather difficult to pon down.
  • Innocent Blue Eyes / Icy Blue Eyes: Sari's light blue eye color matches that of the other Autobots and she's a very kind and caring teenage girl. For the Decepticons, however Sari's eyes are the other trope, as she actually gets serious the few times she comes into contact with them in Season 3.
  • Jet Pack: That forms out of a scooter.
  • Jumped at the Call: She eagerly wanted to help the Autobots in their adventures from day one.
  • Kid-Appeal Character: She's the youngest of the main cast and provides some comic relief.
  • Killer Rabbit: Just ask Mixmaster and Scrapper.
  • The Load: Averted as she is somewhat of a liaison between humans and the Autobots as well as having a key empowered by the AllSpark.
  • Luckily, My Shield Will Protect Me: A weapon that never made it to air.
  • Luke, I Am Your Father: Inverted and otherwise played with with Isaac Sumdac.
  • Magic Skirt:
    • Her skirt usually keeps covering her pelvic area in spite of how short it is. At one point, her leg goes right through it.
    • Subverted in "TransWarped" when she is upgraded. While we see up her skirt in some scenes, it's the standard Cybertronian armor there, so it's okay.
  • Magical Girl Warrior: Her transformation into robot mode is an homage to these, and she boasts a plethora of weapons inside her. You could argue Sari is a borderline example of this as her powers are purely technological in nature.
  • Make Me Wanna Shout: As Bumblebee quickly learned, the sound of her shrieking is very, very painful to Cybertronians. She's weaponized it against the Decepticons on a few occasions.
  • Mid-Season Upgrade: In the most literal sense. Being a Robot Girl, the Key allows her to give herself a Plot-Relevant Age-Up.
  • Missing Mom: Averted - she never had one due to her 'birth'.
    • Although, since the AllSpark is the source of life for all Cybertronians that would technically make the AllSpark Sari's "mother".
  • Mundane Utility: There is virtually no situation in which she wouldn't use the AllSpark key to make things easier.
  • Puberty Superpower: Inverted in that making herself stronger has accelerated her growth.
  • Raised by Robots: She has a robotic tutor educate her, and the Autobots pretty much serve as guardians whenever her father is missing or busy.
  • 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 up her Cybertronian sleeves.
  • Robotic Reveal: It is eventually revealed that she's a techno-organic Cybertronian.
  • Sixth Ranger: At least, she was by the time of the finale. She grew into the role over the course of Season 3.
  • Socially Awkward Hero: Has a much better time getting along with giant robots than kids her age. Justified, as she was home-educated, and spent most of her time around robots anyway.
  • Super Strength: After her AllSpark upgrade, she can effortlessly lift a full oil drum with each hand, even in her human form.
  • Tagalong Kid: She used to be this to the Autobots before she Took a Level in Badass.
  • Technopath: She gains control over machines after her upgrade.
  • Tinman Typist: After her upgrade, her fingers interface with whatever computer system she hacks into.
  • Took a Level in Badass: She becomes a more capable ally to the Autobots than ever after her upgrade, thanks to gaining some new abilities. Subverted, however, as Sari's first official fight actually has her overload due to the AllSpark energy flowing within her, and later episodes show that, while still far more badass than before, Sari still doesn't reach quite the same level of badass and has far less weapons at her disposal. Word of God explained that Sari's weapons have been mostly disabled by Ratchet and that she needs to be able to control energy consumption first in order to truly master them, something that would have likely happened in Season 4 had it not been cancelled.
  • Twofer Token Minority: Female, Indian, cyborg.
  • 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.
  • Unwitting Instigator of Doom: It was Sari using her key to enter her dad's lab that caused Megatron to reawaken.

    Isaac Sumdac 

Professor Isaac Sumdac

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.

  • Accent Adaptation: In the German dub, he is given a Chinese accent.
  • 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.
  • Adult Fear: He chose to raise Sari in isolation for fear of her alien nature being discovered. When Sari finds out about this, it throws their whole relationship into question. And he almost loses her right after.
  • Bollywood Nerd: He's a genius inventor and Indian.
  • Ditzy Genius: He's a brilliant inventor, but unfortunately he's also forgetful and has poor judgment of the people who try to deceive him.
  • Forgets to Eat: "When was the last time you ate?" "What is today?"
  • Honest Corporate Executive: His only real "crime" is withholding his knowledge of Megatron and designing his tech around him. Even then, he had no knowledge of what Megs was upon finding him, the legality of salvaging alien robots is probably not well established, and the only reason he didn't tell Prime decades later is out of shame.
  • Horrible Judge of Character: Despite Megatron's menacing nature, aggressive tone, and fairly obvious choice of words, Isaac trusts him entirely and believes every word he says right up until it's too late.
  • Manly Tears: He cries at the end of the Season 1 finale when Megatron takes him captive, especially given what he had learned earlier that day.
  • My God, What Have I Done?: At the end of "Megatron Rising", having realized that that robot he was helping this whole time was actually the Big Bad.
  • Nice Job Breaking It, Hero: Sari starts the overall story of the series by accidentally reactivating Megatron.
  • Older Than They Look: Since he saw Megatron fall to Earth 50 years ago, he's at least 60 years old.
  • Once Done, Never Forgotten: Working for Megatron, as Bulkhead often brings this up.
  • Open-Minded Parent: He loves his daughter even after unlocking her Cybertronian powers and aging up into adolescence.
  • Robot Master: He creates and controls a lot of robots.
  • Sdrawkcab Name: His last name is "Cadmus" backwards.
  • Skunk Stripe: He has a white S-shaped stripe on his hair.
    • Retcon: We see him with it during flashbacks in Season 1, but in Season 3 it's revealed he got it when he touched the protoform that became Sari.
  • Technological Pacifist: He says so himself that his company does not make weapons.
  • Truly Single Parent: Sort of. Maybe. He's the only human parent, at any rate.
  • Unwitting Instigator of Doom: Twice over, in that he was not only helping Megatron due to his Horrible Judge of Character, but never got around to making any sort of legal citizenship for Sari. The net result was the former coming back to terrorize the world and the latter being kicked out of her own home and life by Powell because she didn't legally exist in any capacity.

    Captain Fanzone 

Captain Carmine Fanzone
Voiced by: Jeff Bennett / Nobuo Tobita

"A technophobe is someone who fears technology. Does this! Look! Like! FEAR TO YOU?! *smashes a phone*"

The loud-mouthed captain of the Detroit Police Department (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. Ironically, Fanzone is also the first human to visit Cybertron and most of the residents fear him because of his organic nature.

  • Acrofatic: He's a Big Eater, but he can kick some serious ass.
  • A Day in the Limelight: The episode featuring him and Ratchet (hilariously, named by his Catchphrase) being sent to Cybertron. Hilarity Ensues then some Mood Whiplashes.
  • Badass Normal: He's a useful ally to the Autobots even though he's just a normal man.
  • Born in the Wrong Century: He doesn't really approve of the inconveniences of modern tech.
  • Catchphrase: "This is why I hate machines!" He also hates kids and lawyers, but above all else, he hates tech support.
  • Child Hater: Admits to being one in "Mission Accomplished", though in his defense, he said so after Sari was making a list of extensive demands while the Autobots suggested that he be Sari's legal guardian.
  • The Commissioner Gordon: He's the main authority figure the Autobots work with.
  • Crouching Moron, Hidden Badass: Despite being a bit bumbling, he actually fights competently alongside the Autobots on several occasions.
  • Da Chief: He often gets angry at the Autobots whenever they mess up or inadvertently inconvenience him.
  • Eyes Always Shut: Though it appears to vary by episode (and animation studio)
  • Failed a Spot Check: By the time he arrives at a military base to investigate the ruckus caused by Blitzwing and Lugnut, the two Decepticons have scanned plane modes for themselves and hid among the jets present. Captain Fanzone angrily asks how the Decepticons could simply disappear into thin air, seemingly forgetting that Transformers can disguise themselves as vehicles and not noticing that the Decepticons' plane modes sport bizarre purple paintjobs that are hugely out of place among the normal military vehicles. Even more incongruously, due to his status as a Triple-Changer, Blitzwing's plane mode has tank treads under its wings in place of landing gear.
  • Fantastic Racism: He has plenty of disdain for machines. Especially since a lot of times he's at the expense of gags involving them. However, he's always willing to help the Autobots in times of need and his disdain never veers into outright hatred like it does with Meltdown.
  • Jerk with a Heart of Gold: He's often very grumpy, but he's an honest police officer and helps the Autobots whenever they need it.
  • Noble Bigot with a Badge: He repeatedly states "This is why I hate machines." That doesn't stop him from working with the Autobots, helping them, or saving them.
    • He also recognizes the good bots from the bad ones.
      "This is why I hate machines." (looks at Sentinel) "Certain machines more than others."
  • Reasonable Authority Figure: He accepts that the Autobots have noble intentions.
  • 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?
  • Technophobia: Dislikes machines, and the ones he does use tend to be oddly old-fashioned for such a futuristic setting.
  • 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.
  • Walking Techbane: This is why he hates machines. They seldom work for him the way he wants them to.
  • Why Did It Have To Be Robots?: Parodied when the Elite Guard make a public arrival in Detroit.
    "Robots. Why did it have to be robots?"

    Porter C. Powell 

Porter C. Powell

Voiced by: Bumper Robinson / Toru Okawa

"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.
  • Corrupt Corporate Executive: He's very sleazy and often does questionable things with his businesses. One of his most heinous violations, however, would be in the tie-in comic story "The insincerest Form of Flattery", where he tried to sell a bunch of SWAT Vehicles named after Bulkhead without the Autobot's permission, used Manipulative Editing to make it look like the vehicles' namesake approved of them, and was later made to confess that he sold the vehicles even while aware that they were completely unsafe.
  • Hate Sink: Aside from cutting funding to Promethus Black in "Total Meltdown", everything Powell does just makes him more and more of a hatable Jerkass, the biggest offense being when he kicked Sari Sumdac out of her home and usurped ownership of Sumdac Systems all the while smugly reminding her that she can't prove she legally exists.
  • Jerkass: Big time, especially when he took sadistic glee in kicking Sari out of her home after exposing there was no legal proof she existed.
  • Jerkass Has a Point:
    • Downplayed. His defunding of Prometheus Black was a sound business decision as Black had not only failed to deliver a product but had also brought legal action down on himself. Since this was before Powell's characterization as a money grubbing asshole the scene frames his actions as sympathetic and logical. With Powell's later characterization as a Corrupt Corporate Executive this action stands out as one of the more sensible and less assholish things he'd done. Even if he helped kickstart Black's Start of Darkness, Black wasn't the most sympathetic of characters.
    • Similarly, while he was being an absolute jerk about it, he is right that a child shouldn't be running a massive, multi-billion dollar robotics company.
  • Karma Houdini: He gets away with all the shit he pulls... well, until things start going pear-shaped for him starting with "Black Friday".
  • Karma Houdini Warranty: His luck starts slowly running out as the season progresses. First, Ratchet threatens to throw him and the mayor into the river if they don't settle a contract dispute over malfunctioning garbage bots. Then, when Prometheus Black is busted out of jail, not only do his attempts to make it seem that Sari did it fail miserably, but his lab is broken into, he's tossed around and frightened by Grimlock, and Fanzone threatens to arrest him for causing a public disturbance leaves him completely stunned. Then, when Sumdac comes back, he's not only fired, but Sari angrily blasts him with her newly discovered Cybertronian abilities. And to put the cherry on top, he tries selling his own brand of Soundwave toys, but when said toys end up nearly enslaving all of Detroit under the real Soundwave's thrall, he's left in ruin by the mass demand of recalls and refunds.
  • Kick the Dog: When he throws Sari out of Sumdac Tower, he continuously gloats about how she can't prove that she legally exists.
  • Kick the Son of a Bitch: In his first scene, he cuts off his funding to Prometheus Black. Given what an asshole Black already was, it's not hard to see what Powell did as karmic.
  • 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 being a "public nuisance". The third season begins with him being kicked out of Sumdac Tower when Professor Sumdac regains control of his company. Much later in "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.
  • Making a Spectacle of Yourself: He wears big pink-lensed glasses.
  • Mysterious Middle Initial: It's never been revealed what the initial "C" stands for.
  • Smug Snake: He's not very respectful or humble towards anyone.
  • Villain with Good Publicity: He's very well respected by the public in spite of being a highly contemptible dick. Well, he was until "Human Error", thanks to the whole fiasco with Soundwave.
  • 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.

    Mayor Edsel 

Mayor Edsel


A silent mayor who lets his secretary do all the talking.

  • Silent Bob: Even though he never speaks, no one has trouble understanding him.
  • Silent Partner: Flipped around from what you'd expect.
  • The Voiceless: He needs his assistant to interpret him.

    The Witwicky Family 

The Witwicky Family

Voiced by: Corey Burton (Spike), Tara Strong (Carly and Daniel) / Katsuyuki Konishi (Spike)

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.

  • All There in the Manual: The AllSpark Almanac books reveal that the family's infant daughter is named Nancy.
  • Ambiguously Related: Spike Witwicky's father Sparkplug Witwicky is also present in this continuity, but he is never seen with the rest of the Witwicky family and is never confirmed to be a Witwicky, which makes it unclear whether he is still Spike's father.
  • Constantly Curious: Daniel Witwicky in the short "Career Day". Optimus Prime introduces himself to Daniel's school, but Daniel won't stop asking Optimus questions about how he transforms.
  • Continuity Cameo: They are based on the characters of the same names from the Generation 1 cartoon.
  • Panicky Expectant Father: Spike Witwicky is visibly nervous when he is seen with a pregnant Carly in "Garbage In, Garbage Out", and he doesn't get any calmer when Ratchet's attempt to drive them to the hospital goes awry.
  • Recurring Extras: Their appearances are generally limited to background cameos.


    Prometheus Black/Meltdown 

Prometheus Black/Meltdown
Voiced by: Peter Stormare / Fumihiko Tachiki

"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.

  • Awesome McCoolname: Prometheus Black
  • Bad Powers, Bad People: His body is made of acid corrosive enough to melt through Autobots, and he's also a depraved Mad Scientist willing to perform human experimentation on even children.
  • 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? The bat one used to be his lawyer.
  • Cool Shades: He wears sunglasses, even after his mutation.
  • Disco Dan: Dresses like he should be at a 70's disco club.
  • Driven by Envy: He’s extremely jealous of Sumdac’s fame and success, and determined to outshine him.
  • Dub Name Change: He's called Dr. Fusion in the French dub.
  • Evil Counterpart: To Isaac Sumdac. Both are scientific geniuses who are quite famous. But whereas Sumdac's specialty is robotics, Black's is biotechnology. While Sumdac uses his robots to benefit mankind, Black uses his biotech for his agenda about organic material being better than machines.
    • Come Season 3, he also counts as one to Sari herself. Both are humans affiliated with a revolutionary tech company who are granted inhuman powers by their encounters with the Transformers, and while Sari fights alongside the Autobots and embraces who she is, Prometheus resents his transformation and seeks to exploit them for his twisted experiments.
  • Evilutionary Biologist: He's a biochemist who creates bio-augmentations for humans, and for his own nefarious schemes.
  • 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.
  • Knight of Cerebus: Of the show's human villains: he's the only one who isn't played for laughs and poses a genuine threat to the Autobots.
  • Mad Scientist: He performs genetic experiments that turn people into deformed monsters and superpowered beings.
  • 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: He'll perform experiments on people regardless of how they are affected.
  • Poisonous Person: Meltdown is a walking acid creature that can melt Transformers with a touch.
  • Right for the Wrong Reasons: He once says Isaac Sumdac merely got lucky with his success in robotics; if only Prometheus knew the half of it...
  • Sesquipedalian Smith: His first name Prometheus is rather sophisticated when compared to his mundane surname of Black.
  • Small Role, Big Impact: Black never appears again after his supposed "death", but Blackarachnia is still using his lab and resources in "Predacons Rising." And as it turns out,creating a "Transforming organic" isn't entirely impossible...
  • Squishy Wizard: His acid, which he can also fire from his hands, will burn through anything, but he's helpless if faced by something that's resistant to it, notably shown when Fanzone grabbed one of his protective suits and overpowered him.
  • The Resenter: He absolutely loathes Isaac Sumdac, viewing him as intellectually inferior and a fraud.
  • Token Super: He's the only human villain with real superpowers, though his condition came from exposure to Mech-Fluid, basically Transformer blood.
  • Unknown Rival: Sumdac knew about him and his company, but he had no idea how much Prometheus outright hated him.
  • Unskilled, but Strong: His acidic powers make him a huge threat, but beyond that he's not very combat capable. When Fanzone neutralizes his powers using a backup acid-proof suit, he takes Black down easily.
  • What Happened to the Mouse?: After he's melted into a puddle in Season 2, he never appeared in the show again.
  • Would Hurt a Child: When his experiments don't get the results he wants he decides to try the procedures out on child test subjects. And then he decides to get even with Sumdac at the same time by abducting Sari. As Fanzone put it, he's a seriously twisted fruitcake.

Nino Sexton/Nanosec

Voiced by: Brian Posehn / Takehito Koyasu

"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.

  • Dub Name Change: In Japanese dub, he goes by "Speed King".
  • Evil Redhead: He has red hair.
  • Line-of-Sight Name: Despite his name, he didn't get the idea for his supervillain moniker until one of his victims claimed his money "disappeared in a nanosec!"
  • Opposites Attract: The man with Super Speed gets interested in a woman who can slow down time.
  • Rapid Aging: A side-effect of the suit was that he'd grow older the more he used it. Slo-Mo fixed him up in Season 2.
  • Steven Ulysses Perhero: Nino Sexton, Nanosec. Oddly enough, he didn't come up with it himself.
  • Super Speed: His power is moving superhumanly fast.
    Angry Archer 

A. A. Archer/Angry Archer

Voiced by: Jeff Bennett / Katsuyuki Konishi

"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.

    Professor Princess 

Penny Princess, Ph.D./Professor Princess

Voiced by: Kath Soucie / Megumi Toyoguchi


A bratty "princess" whose goal in life is to destroy anything "boyish" so the world can be a happier, pinker place.


    Henry Masterson/Headmaster 

Henry Masterson/Headmaster

Voiced by: Alexander Polinsky / Kōsuke Okano

"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).

  • Adaptational Villainy: Headmasters are normally supposed to enable a cybernetic partnership, with the bot gaining an extra perspective from his new partner. Here they're the creation of an unstable, angry manchild with emphasis on forceful control, and no consent from the disembodied bot.
  • Awesome, but Impractical: The Headmaster Units are very powerful and very dangerous machines, especially to Transformers, granting the pilot control of a powerful alien war machine. If the Transformers weren't there, however, their flaws outweigh their benefits. The Headmaster Units are far too heavy for conventional Earth weaponry, and even when he takes over Transformer bodies the size of the thing prevents actual transformation. What the units boil down to are expensive upgrades to already functional weaponry that are more likely to compromise the weapon's infrastructure than provide any major benefits.
  • Beware the Silly Ones: This guy might be an idiot, but outside of Meltdown, he's the only human that manages to actually a pose a danger to the Autobots without any help from the Decepticons.
  • Broken Pedestal: When he first meets Professor Sumdac, he gushes on how he's always admired his work and how he grew up tinkering with his robots. He loses his respect for Sumdac when he gets fired because of his dangerous Headmaster unit demonstration and is chewed out for attempting to make weapons for the company.
  • Bunny-Ears Lawyer: His ludicrous tendency to speak in outdated Internet slang aside, he's still very dangerous to the Autobots and he made the Headmaster unit himself.
  • Catchphrase: "Total ownage, noobs!"
  • Combining Mecha: The Headmaster unit will make any other robot one against their will.
  • Disco Dan: He talks like an early 2000s online game nerd in the 22nd century when "l33tsp33k" was already on its way out when the show premiered.
  • Expressive Mask: It's subtle, but despite being a piece of technology with no mind of its own, the Headmaster Unit sometimes changes to match the presumed expressions of its owner.
  • Expy: He's essentially the same guy as Control Freak.
  • Gadgeteer Genius: He invents his own equipment.
  • Grand Theft Me: His modus operandi is using his tech to steal Cybertronians' bodies.
  • Karma Houdini: Twice he's able to scoot out of legal punishment. First, Porter C. Powell is able to keep him from being charged with nearly destroying all of Detroit. Then, in the same episode, Powell gets him off charges of destruction of property and assault through legal loopholes. Fortunately, karma catches up with him.
  • Karma Houdini Warranty: His third attack on Sumdac ends with his arrest.
  • Leet Lingo: He speaks in outdated Internet slang.
  • Mad Scientist: He uses technology of his own creation in his crimes and is not exactly mentally stable.
  • Mythology Gag: His Headmaster suit is one for the entire "Headmasters" concept in the Generation 1 comics, albeit as a weapon that takes control of an unwilling bot, rather than a symbiotic partnership. Later iterations of the unit even go as far as to give it a Mini-Mecha form.
  • Nice Job Fixing It, Villain: He tries attacking Sumdac just around the same time Sari had angrily disowned him for refusing to tell her about her robotic origins. Doing so leads Sumdac to throw his life on the line for his daughter, causing Sari to forgive him for the whole thing in the end.
  • Psychopathic Manchild: Masterson acts more like an immature teenager than a grown man, considering his speech patterns, his demonstration of the Headmaster Unit to Professor Sumdac, and also carelessly endangering lives while acting like his technology is the coolest thing ever. He gets angry when Professor Sumdac rejects his ideas and fires him, leading him to hold the city of Detroit to get the money needed to make his own company, only to decide to blow up the city anyway when it looks like he got what he wanted just for the thrill of destruction. Getting fired again leads him to try and kill Sumdac and his daughter personally. It's no wonder Professor Sumdac doesn't want him working for his company.
    Henry Masterson: The only thing better than making toys, is breaking toys!
  • Real Men Wear Pink: When he moves into Sari's room in "The Return of the Headmaster", he is quite ecstatic about it and doesn't appear to mind that everything in it is pink and frilly.
  • Steven Ulysses Perhero: His first name begins with H, his surname contains "master", and he calls himself Headmaster.
  • Too Dumb to Live: Yes, overload the solar fusion reactor after you've requested $7 billion, and think the government will want your war bots. That will look good on your resume. It really begs the question as to how Powell manage to get him off the hook the first time and dismiss it as a "misunderstanding".
  • Totally Radical: A somewhat updated example in that his slang is based on Internet lingo.
  • Villain: Exit, Stage Left: His debut episode ends with him getting away.

    Master Disaster 

An evil Australian-accented man who also is the host of an illegal street-racing broadcast.

  • Awesome Aussie: Averted, he's an antagonist.
  • Dub Name Change: He's called Captain Chaos in the Finnish dub.
  • People Puppets: His AllSpark-amplified remote allows one to control vehicles, which presumably allows him to rig the races.
  • Villain of the Week: His only significant role in the show is as an antagonist in "Velocity". He is arrested by Fanzone in his debut episode.

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.


How well does it match the trope?
