The Movie's Antagonists


Yokai / Robert Callaghan

Voiced by: James Cromwell
Appearances: Big Hero 6

A mysterious individual with control over a massive swarm of microbots. For some reason, Yokai is trying to murder the titular heroes, and Fred believes that it is simply a case of them having seen too much.

  • Achilles' Heel: His microbots serve as both a powerful weapon and a deadly crutch. Yokai is completely reliant on his microbots to fight. Strip him of them and he's utterly helpless. Hiro and the gang manage to defeat him by sending his microbots into the transporter, depriving him of his only weapon.
  • Alas, Poor Villain: He tries to get revenge on Krei because of what happened to his daughter. When Hiro retrieves his daughter, he realizes his actions were futile and he is going to jail just for meaningless destruction of property.
  • All There in the Script: His name is only given in promotional materials associated with the film. In the actual film, he doesn't have one, only being referred to as "Mr. Kabuki" after his mask.
  • Anti-Villain: His actions are horrible and menacing, but he's also a grieving Papa Wolf who clearly shows remorse at the end.
  • Badass Bookworm: Given his true identity is Robert Callaghan, a brilliant roboticist and he's a ruthless No-Nonsense Nemesis, he definitely qualifies.
  • Badass Longcoat: This guy can control microbots with his mind and styles himself with a sinister-looking longcoat.
  • Berserk Button: When Krei described the apparent death of his daughter as a "setback".
  • Big Bad: He is using microbots to recreate the teleporter that killed his daughter in a plot to get revenge on Alistair Krei. He causes Tadashi's death and is trying to kill the heroes to keep all this a secret.
  • Bitch in Sheep's Clothing: As Callaghan, he has the appearance of a kind-hearted teacher earlier in the film. However, when his identity as Yokai is revealed, it's shown as nothing more than a façade to mask his heartless Jerkass nature and how much of a hateful and vengeful wreck he actually is.
  • Broken Ace: Callaghan is a brilliant and gifted scientist and teacher, but he's so consumed by his grief and desire for revenge that he just doesn't care about any of that.
  • Broken Pedestal: When it is revealed that he is Callaghan.
  • Canon Character All Along: Inverted. His character design (primarily the kabuki mask) is loosely based off the Marvel Comics villain, Lord Deathstrike, but his true identity is the Canon Foreigner, Callaghan.
  • Classic Villain: Because Yokai is completely silent, his motivations remain a mystery for a good portion of the film, leaving Genre Savvy Fred to interpret his actions and appearance using this trope as a guide. Ultimately, it's Subverted because Fred while correct about the genre was wrong in his assumptions. When Yokai is revealed as Professor Callaghan, we learn that he is not inherently evil and intending to be a perennial villain but that he's seeking revenge on one person and so consumed by his grief that he doesn't care about bystanders that might be hurt in the process.
  • Collapsible Helmet: The mask acts like this in a limited fashion near the end. It slides up over Yokai's face with no indication how, when he needs to speak face to face, and then slams back down when it's time to fight.
  • Combat Pragmatist: Yokai is a No-Nonsense Nemesis, using any objects in his immediate area as weapons to be thrown by his microbots at his opponents. As The Voiceless, he doesn't stop to banter or gloat, and instead operates with cool efficiency.
  • Comic-Book Movies Don't Use Codenames: He's never referred to as Yokai in the film.
  • Cool Mask: A Kabuki mask. He uses it to control the microbots. The heroes remove it from him, stripping him of his powers.
  • Dark Is Evil: Is seen wearing all black, his microbots resemble a Living Shadow when attacking, and he is the Big Bad.
  • Darth Vader Clone: He's an antagonist who wears all black, sans his kabuki mask, and his backstory is that he was formerly a figure of respect among the scientific community, which he threw away for vengeance against Krei for what happened to his daughter.
  • Even Evil Has Loved Ones: His plan is to get revenge on Alistair Krei whom he believes caused the death of his daughter.
  • Evil Counterpart:
    • To Hiro. Both are genius inventors who lost a loved one, but unlike Hiro, who sees the error of his actions and learns to accept his loss, Yokai is too mad with grief to change, and it's this that fuels his actions. He seems to feel guilt at the end of it all. Also, unlike Hiro, who has friends and other loved ones to help him with his loss, Callaghan seems to have kept his pain private. They have similar Berserk Buttons also.
    • To Tadashi. He occupied a similar role as an inspirational mentor to Hiro and his friends. But whereas Tadashi sacrificed his life for those he cared about, Callaghan doesn't care who he hurts in his quest for revenge.
  • Evil Wears Black: Lampshaded by Fred's line "That mask, the black suit... We're under attack from a super villain, people!"
  • Fallen Hero: He was once an inventor and teacher who wished to shape the future, but he became blinded by his own grief.
  • Freudian Excuse: He thought his daughter died in an experimental portal.
  • He Who Fights Monsters: Became this after his daughter's apparent death, driving him to extremely desperate measures to take revenge on Krei.
  • Hoist by His Own Petard: Hiro and the gang manage to defeat Yokai by sending his microbots into the very transporter he is using to exact his revenge on Krei, stripping him of his only weapon.
  • Hypocrite: Given that the motivation for his vengeance and his villainous actions is that his daughter apparently perished due to someone else's actions, he is surprisingly unsympathetic towards Hiro for the death of Tadashi, which he caused through his actions as Professor Callaghan. Not to mention, he has no qualms about trying to straight-up murder his own students, numerous times, when they inconvenience his plans or putting the city at risk to get to Krei during the climax. Despite his rage at Krei, Callaghan himself is an extremely callous, insane and self-involved man.
  • Imagination-Based Superpower: The microbots are essentially this. Hiro, when exhibiting them even states the only limit for what they can do is your imagination.
  • Irony: Yokai uses the lone functioning portal as the instrument to avenge his daughter's death. Which turns out to reveal that she's still alive and all the destruction caused by his vengeance was unnecessary and pointless.
  • Jerkass: When a distraught Hiro confronts Callaghan over the death of his brother, he coldly and rudely dismisses it as being Tadashi's fault for trying to save him, mostly out of impatience as he was demanding Hiro give him back his mask, while Hiro was questioning his survival. To say nothing of all the times he tried to murder Hiro and his friends before and after this scene, for getting in his way. Also doubles as a Jerkass Woobie due to his motivation.
  • Knight of Cerebus: When Yokai appears, the mood significantly darkens.
  • Lightning Bruiser: When riding his microbots, Yokai is incredibly swift, and the microbots themselves have immense strength and give him plenty of destructive power.
  • Long-Range Fighter: Due to not having any powers of his own, Yokai relies heavily on his microbots to fight. He keeps well out of grabbing range.
  • Malevolent Masked Man: The main villain is a man in a trench coat and Kabuki mask with an army of microbots he controls with telepathy. His design would be the sort of thing you'd expect to see in a hardcore action game, not a Disney film.
  • Meaningful Name: "Youkai" is the Japanese word for "ghost", "apparition", or "phantom". Fitting for a mysterious villain who hides his identity, doesn't speak, and shows up out of nowhere. It becomes even more fitting when it's revealed that he's actually Callaghan who at the time of Yokai's first appearance was presumed to be dead.
  • The Mentally Disturbed: According to Baymax's scans, he suffers from acute stress disorder as well as emotional instability.
  • My God, What Have I Done?: Callaghan's face after being arrested and seeing his daughter alive implies he's feeling immense guilt for his actions.
  • Names to Run Away from Really Fast: Youkai are creatures, spirits, monsters, and demons from Japanese Mythology. Fitting for a creepy villain with powers that seem supernatural.
  • Nanomachines: His microbots are his Weapon of Choice. However, unlike most examples, these aren't self-replicating and he only has a finite supply. Hiro and the gang exploit this by sending them into the transporter, depriving Yokai of his only weapon.
  • Never My Fault: He coldly declares that Tadashi was responsible for his own death, rather than admit that it was his actions that directly lead to Tadashi's death. He was also impatient and revenge-driven when he says this, so at least from his point of view, he doesn't have time to think about it right now.
  • No-Nonsense Nemesis: Yokai is a Combat Pragmatist, using any objects in his immediate area as weapons to be thrown at his opponents. As The Voiceless, he doesn't stop to banter or gloat, and instead operates with cool efficiency.
  • Outliving One's Offspring: Subverted. He thought that his daughter died in an experimental portal, but she turns out to be alive.
  • Papa Wolf: Deconstructed. His daughter's apparent death is what drives his desire for revenge against Krei, whom he holds responsible.
    Yokai: Setback!?! Was my daughter a setback!?
  • Pyrrhic Victory: Yokai manages to destroy the new Krei Tech Industry headquarters, but his daughter is revealed to still be alive, and his actions resulted in the death of Tadashi, the loss of his reputation and status, a likely prison sentence and Abigail and the rest of the world will know what he did.
  • Redemption Rejection: Yokai ignores Hiro's pleas for him to stop, having been pushed too far into revenge. Alistair Krei interjecting with a panicked attempt to buy his way out of trouble at the worst possible moment didn't help. His expression at the end, however, reveals this may not be the case anymore.
  • Revenge: His primary motive. Alistair Krei, while experimenting with a massive teleportation machine, seemingly killed his daughter, wracking Callaghan with immense grief and leading him to don the Yokai alias to exact revenge.
  • Revenge Before Reason: Yokai's desire for revenge against Alistair Krei for his daughter's apparent death pushes him beyond the realm of any reason or sense. He ignores Hiro's plea for redemption and instead opts to swallow up an entire building area with his portal solely to get his revenge.
  • Shadow Archetype:
    • To Hiro. Both are genius inventors who lost loved ones. But whereas Hiro managed to see the error of his ways and moved on from his grief with the help of his friends, Yokai had no one to turn to and couldn't let go of his pain. He's a dark reflection of how Hiro could have ended up.
    • To the rest of the Big Hero 6. Like their suits, the technology he uses is stuff that he developed and laid the groundwork for, but which required Hiro's miniaturization skills to be effective in combat. Unlike the Big Hero 6, he stole it from Hiro and uses it for destructive purposes rather than heroics.
  • Shaping Your Attacks: A staple of his fighting style. Yokai's microbots can form themselves into whatever shape he desires, such as spears to impale opponents, barriers to protect himself or trap enemies, or a large tidal wave to smother them.
  • Silent Antagonist: He never speaks until his identity is revealed.
  • Silent Snarker: His body language in his first proper fight with Big Hero 6 is, in general, fairly annoyed and impatient, but particularly when he traps Wasabi; he points his left hand to his right, with Wasabi being thrown afterward.
  • Super Weapon, Average Joe: While very intelligent, his age and possession of a very potent weapon system ventures into this and Squishy Wizard territory.
  • Tragic Villain: A once kind and caring father turned grieving villain on a Roaring Rampage of Revenge due to the seeming death of his daughter.
  • Tranquil Fury: His default mood after he thinks his daughter's dead.
  • Two Aliases, One Character: Professor Robert Callaghan and Yokai are one and the same.
  • The Unfettered: He will avenge his daughter's death no matter who or what has to be destroyed to do so. Woe to any who stand in his way.
  • Ungrateful Bastard: When it's pointed out that Tadashi died trying to save him, he responds that it was his mistake for doing so.
  • Unskilled, but Strong: His fighting style suggests this. While the microbots can form any shape he desires and give him plenty of destructive power, Yokai is far less flashy than most users of the Shaping Your Attacks trope and his fighting style mainly boils down to either impaling enemies, trapping them in barriers, or burying them alive in his microbots. That said, given how strong the microbots are, how his supply of them is seemingly endless, and how much of a No-Nonsense Nemesis he is, he doesn't need anything else.
  • Vengeance Feels Empty: You can kind of see it on his face when he's arrested. Yeah, he paid Krei back for mishandling the portal experiment by destroying his headquarters, but his daughter didn't perish in the portal like he thought. But since he took revenge before finding that out, now he's branded a criminal and can't even enjoy the very thing he took revenge for.
  • Vile Villain, Saccharine Show: Yokai is surprisingly dark and menacing for a film that's otherwise rather lighthearted and adventurous, commanding an army of little robots that can construct anything and he isn't afraid to use them to cause all manner of destruction and family-unfriendly scenarios.
  • Villain Has a Point: He coldly tells Hiro that Tadashi's death was his own fault. It was a major Kick the Dog moment, but he still makes a pretty good point; Tadashi ran into a building fully engulfed in flames with no protection or equipment in a futile attempt to try to find Callaghan, when he had no idea where he was. Noble as it may have been, it was a monumentally stupid thing to do, and Tadashi made the decision on his own accord.
  • Villainous Breakdown: "THIS ENDS NOW!"
  • The Voiceless: During the first encounters with Yokai, he is silent and menacing. He only starts talking after being exposed as Callaghan.
  • White Mask of Doom: He wears a kabuki mask that's mostly white with markings, highlighting his eerie appearance.
  • Woobie, Destroyer of Worlds: He is driven entirely by a desire for revenge on Krei for apparently causing his daughter's death.
  • Would Hit a Girl: Has no qualms about killing either Honey Lemon or GoGo.
  • Would Hurt a Child: He nearly kills Hiro (a 14-year-old) twice and his friends once, even though he could have simply evicted the latter from the warehouse. Callaghan doesn't apologize for it when Hiro and the others unmask him.
  • You Killed My Father: A daughter variant. Yokai is actually Callaghan, and the reason he became "Yokai" is to take revenge on Krei who apparently caused his daughter's death. His daughter turns out to be alive and well.

    Mr. Yama 

Mister Yama
"Who is next? Who has the guts to step into the ring with Little Yama?"'
Voiced by: Paul Briggs
Appearances: Big Hero 6 | The Series

A sleazy underground bot-fighter and the boss of a crime ring.

  • Acrofatic: In "The Bot Fighter" episode of the series, the team finds footage of Yama taking samba dance lessons, and he's quite talented at it for someone who has the girth of a sumo wrestler.
  • Ascended Extra: He's a minor threat to Hiro, and quickly overshadowed by Hiro deciding to attend SFIT in the film. He's a recurring villain in the TV Series.
  • Benevolent Boss: Despite being a Jerkass, he treats his thugs fairly well. If you exclude the one thug Yama used as a Human Shield.
  • Berserk Button: He does not like hustlers, and he tries to attack Hiro when Hiro hustles him.
  • Brought to You by the Letter "S": His jacket has the character for his name in Japanese, "山", written on the back.
  • Butt-Monkey: Something frustrating always seem to happen to him whenever he's on screen.
  • Creator Cameo: Voiced by the film's head story writer.
  • The Dragon: In the series premiere, he's Obake's main lackey. After his failure to retrieve Granville's paperweight, it appears that Yama no longer works for the villain.
  • Evil Counterpart: Though not necessarily evil per se, he was created to be a sort of "what if" possibility for Hiro; namely, what he might wind up being like if he continues down the road of hustling back alley bot-battles.
  • Fat Bastard: He's as unpleasant as he is huge.
  • Genius Bruiser: While he prefers to throw his own weight around, he is a bot fighter who likely created Little Yama. He also uses a robot army in the TV series to distract the police from his actual goal of stealing a valuable alloy from the dean's office.
  • High-Altitude Interrogation: Does this twice in the premiere, the second time to Hiro.
  • Hypocrite: He dismisses Hiro's request for a rematch, saying that nobody likes a Sore Loser. After his bot is defeated, he and his goons decide to beat Hiro up.
  • Jerkass: He is very condescending towards his opponents.
  • Knuckle Cracking: Delivers the neck crack variant as he and Hiro face off prior to their first bot fight.
  • Laser-Guided Karma: Gets arrested along with all of his thugs, everyone that showed up at the bot fight, and the Hamada brothers.
  • Meaningful Name: "Yama" is Japanese for "mountain", which is a pretty apt description of him.
  • Oh, Crap!: Has one when Obake calls him after Yama failed to retrieve an item for him.
  • Out of Focus: Over the course of Season 1, his role decreases in favor of the new antagonists introduced in the series, and he isn't part of Obake's inner circle by the finale.
  • Smug Snake: He's an arrogant brute who believes he's the best bot fighter around.
  • Starter Villain: He's the first antagonist Hiro faces, both in the movie and in the series.
  • This Cannot Be!: His reaction when Hiro's megabot annihilates his Little Yama bot.
  • Would Hurt a Child: Yama was about to beat up a 14-year-old.
  • Yakuza: Yama has partaken in such San Fransokyo criminal activities as illegal underground bot fighting, thievery, loansharking, and murder. In the series premiere, he serves as The Dragon to Obake.

    Yama's Thugs 

Yama's Thugs

Voiced by: Andy Richter ("Basketball Shirt"), Khary Payton ("Tank Top"), David Shaughnessy, Scott Adsit, Diedrich Bader
Appearances: Big Hero 6 | The Series
Yama's loyal henchmen that listen to his every order. Though Yama has a lot of people working for him, the ones pictured are his main right-hand men.
  • Badass Biker: A bunch of them chase Hiro with motorbikes in "Mini-Max".
  • Badasses Wear Bandanas: One of Yama's main thugs wear one.
  • Beard of Evil: Basketball Shirt and Tank Top have these.
  • The Brute: All of them.
  • The Chew Toy: Each time they're on screen, they get beaten in some way. Since they're bad guys, it's satisfying to watch.
  • The Dragon: Are these to Yama.
  • Human Shield: Yama uses one of his knocked-out thugs to protect himself from Honey Lemon's chem-balls in "Baymax Returns".
  • Mooks: Yama's personal ones. In the series, they basically exist to get their asses kicked by Big Hero 6.
  • Nice Hat: "Basketball Shirt" wears a grey beanie in the movie, and a blue one in the series.
  • No Name Given: We don't know their real names. Two of the henchmen trio are credited as "Basketball Shirt" and "Tank Top" in the series.
  • Terrible Trio: While Yama has many mooks working for him, the ones pictured from the movie are his main henchmen.
  • Undying Loyalty: To Yama. They follow his every orders.
  • The Silent Bob: The thug with the grey bandana is the only one who hasn't spoken yet.
  • Sleeves Are for Wimps: One of Yama's thugs wears a tank top.
  • Stun Guns: Use a taser tod on Baymax's exoskeleton in "Baymax Returns".
  • Would Hit a Girl: Basketball Shirt tries to punch GoGo in "Baymax Returns."
  • Would Hurt a Child:
    • Were about to beat up Hiro in the movie if not from Tadashi's intervention.
    • Did not mind dropping Hiro off a building under Yama's orders in "Baymax Returns".

Obake's Team


Obake/Bob Aken
"Tragedy has molded us, intellect has driven us. Now we stand at the doorway to greatness!"

Voiced by: Andrew Scott
Appearances: The Series (debut: "Baymax Returns")

A mysterious villain in San Fransokyo.

  • Affably Evil: He's relatively soft-spoken (although this can easily come off as sinister), seems to have some level of legitimate respect for Big Hero 6, and actually treats Globby and Noodle Burger Boy quite well. He also has potentially dangerous plans for San Fransokyo. He respects Hiro enough to try and make him his apprentice, and when his plan completely fails, sends Baymax away to save him.
  • Alas, Poor Villain: After his plan to recreate "The Great Catastrophe" was stopped by Big Hero 6, he goes to a Villainous BSoD that's saddening to see.
  • Ambiguously Evil: While its made clear that Obake became the villain that he is after the accident that caused his tumor, it's left debatable over what his true nature was. It's possible that he was once a genuinely idealistic student, but the lab accident left him without any moral constraints and drove his obsession with science to monstrous extremes. On the other hand, it's also possible that he had already been a science-obsessed maniac, and the accident merely caused his true nature to come to light.
  • Ambiguously Human: He seems to be a normal man, but the fact that his face sometimes glows neon purple suggests otherwise. It's eventually revealed that it's the result of the brain damage he received after his failed experiment.
  • Analogy Backfire: He tries to use the story of The Fall of Icarus in persuading Hiro to join him, rationalising that Icarus fell because he didn't build better wings. However, Hiro points out that the reason Icarus fell was because "he flew too high". In short, Icarus fell because he tried breaking his limits, which is what ultimately caused Obake's undoing.
  • Arc Villain: He's the main antagonist of Season 1, and seemingly disposed of by the end of the season.
  • Ax-Crazy: His incident left him rather mentally unstable to the point where he's obsessed with unbridled destruction and cannot decide right from wrong. Globby realizes he's that insane.
  • Bad Boss: When Yama fails to grab the object he needs in the pilot, Obake comes just short of murdering him before Yama reveals he's built a makeshift robot army. Played with in future episodes when it's shown he treats his other minions more tactfully. Given Obake's personality, it's likely that he treats Yama the way he does because it gets results.
  • Big Bad: Of Season 1.
  • Benevolent Boss: Treats his minions well even if he is somewhat condescending towards them.
  • Brainy Brunette: Has jet black hair and is a former Teen Genius turned Evil Genius.
  • Broken Ace: He's an extremely gifted, intelligent and visionary man. However, the accident from an experiment gone wrong left him with a brain tumor that makes him unable to perceive right from wrong.
  • The Cameo: He's made a cameo appearance in almost all of the Big Chibi 6 shorts.
  • The Chessmaster: The man makes lots of plans for some purpose only he knows about. When he starts to plot against Big Hero 6, he launches a series of attacks against them just so he can gather intel. The implication is that when he has enough information he'll start his real plan.
  • Childhood Brain Damage: Suffers a brain tumor that is slowly spreading throughout his brain as a result of the failed lab experiment.
  • Cold Ham: He can be rather bombastic, but still in a quiet tone of voice.
  • Contrasting Sequel Antagonist: Yokai was fairly taciturn, direct in doing his deeds, and had a very serious personality. Obake, meanwhile, is much more talkative, prefers hired guns to get things done (as well as keep his existence a secret), and is much more eccentric. Callaghan is a teacher of the San Fransokyo Institute, while Obake was a former student.
  • The Cracker: He's hacked just about everything, and if he hasn't he can do so easily.
  • Deadpan Snarker: Has a sarcastic side, reserved at his henchmen and of course, Big Hero 6. Helps he's being voiced by Andrew Scott.
    Globby: I did what you asked, but I'm gonna be honest, I don't get it.
    Obake: Well, of course not. It's beyond you.
  • Do Not Adjust Your Set: Hijacks Yama's TV to tell him to steal Granville's paperweight.
  • Driven to Suicide: Implied. Upon his plan being foiled, the last we see of him, is him dejectedly sitting in his chair as his lair collapses around him. The final shot focuses on his programming chip, which may hint that he's (or at least his personality is) still alive.
  • Eerie Pale-Skinned Brunette: Has an extremely pale skin complexion and dark hair, making his appearance more sinister.
  • Even Evil Has Loved Ones: He shows affection for his robotic "daughter" Trina.
  • Evil Brit: He has a crisp English accent despite living in an American city influenced heavily by Japanese culture.
  • Evil Eyebrows: He has dark, high-arching eyebrows.
  • Evil Feels Good: His comment to Baymax implies that he hasn't had his brain damage treated because he enjoys the freedom it gives him from his moral compass. It certainly fits in with how he hates limits.
  • Evil Genius: He's one of the few people who rival Hiro in intellect, which he uses both to create advanced technology and to manipulate people for his Evil Plan.
  • The Faceless: In his first appearances he's either seen from the back, or his face is in shadows. His face is abruptly revealed in the seventh episode, without any real drama.
  • Famous Last Words: "I am satisfied with my care."
  • Fatal Flaw: His inability to recognize that just because you can do something doesn't mean you should. Granville's lack of supervision combined with his brain damage has driven him to complete his goals, no matter how dangerous or who gets hurt in the process.
  • Faux Affably Evil: Despite his level of respect for Big Hero 6 and for Hiro's intelligence, his plan still involves needlessly endangering countless innocent people.
  • For Science!: His primary motivation. He wants to destroy San Fransokyo and rebuild it into a city of science where he can experiment freely without any limitations.
  • Freak Lab Accident: As a teenager, he was Professor Granville's star student, and she gave him access to the labs after school hours. She had no idea Obake was working on an energy amplifier, a dangerous experiment, who turned awry and gravely injured him. One of the aftereffects of his accident is a brain damage that causes the left side of his face to glow, and to not defer right from wrong.
  • Going Down with the Ship: After his plan is foiled and his lair begins to collapse, a dejected Obake refuses Baymax's offer to save him, instead opting to let himself go down with his lair.
  • Guy Liner: The black traits that define his eyes looks a lot like eyeliner.
  • Hidden Agenda Villain: It's made clear in the pilot that he's planning something for San Fransokyo, and it likely isn't good.
  • Icy Blue Eyes: Has blue eyes and is a creepy, ruthless figure.
  • Ink-Suit Actor: He bears some resemblance to his voice actor, Andrew Scott.
  • Kick the Dog:
    • Tricked Hiro into thinking that his dead brother Tadashi was alive.
    • When he steals Hiro's power amplifier from his lab, he casually tosses Tadashi's cap aside.
  • Knight of Cerebus: While Obake still has some comedic traits, stemming from much of his quietly bombastic personality, he's also shown to be much more adept and subtly creepy than most of the other recurring antagonists.
  • Leitmotif: Ominous ambiance tends to play around him.
  • Lean and Mean: A tall, thin man and the antagonist of Season 1.
  • Mad Hatter: He's aware of his own brain damage, but is content with it because it allows him to pursue his experiments without any guilt holding him back.
  • Mad Scientist: Literally so, as Baymax scans that he's suffering treatable damage to the part of his brain responsible for discerning right from wrong.
  • Manipulative Bastard: He is very talented at either manipulating people or at least predicting how they will act. As an example, he concocts an elaborate scheme where he tries to steal a chip that came into Krei's possession. The chip contains Obake's spyware, and Obake only tries to steal it to trick Krei into installing it.
  • Meaningful Name: "Obake" is a name for a type of shapeshifting youkai. Over the course of Season One, he reveals himself to be a pretty effective Master of Disguise.
  • Never Found the Body: Hiro and Baymax never found his body while searching amongst the debris of his destroyed lair.
  • No Sense of Personal Space: When he has Hiro's captive, he doesn't respect his personal space, which obviously makes Hiro uncomfortable.
  • Not So Different: Despite Hiro stating he's nothing like him, Obake thinks otherwise. And he's right. Both are (were in Obake's case) teen geniuses with difficulty respecting their limits under Professor Granville's teaching. The difference is, Hiro realizes this and learns to respect his limits, while Obake never does and thinks they're only holding him back because of his Child Hood Brain Damage, which causes him to lose his sanity to villainy.
  • Not-So-Well-Intentioned Extremist: While he may believe his plan to destroy San Fransokyo will result in a place of unrestrained scientific progress and learning, he is also primarily doing this to be "remembered" and so that no one can limit his research. Due to his morality being heavily skewed by his brain damage, he sees scientific progress as an end to itself and doesn't care much about the people it's supposed to benefit.
  • Omnicidal Maniac: His whole plan is to destroy all of San Fransokyo and remake it into a new city for the gifted.
  • Only Known by Their Nickname: "Momakase" is probably her supervillain alias, and her real name is unknown.
  • Peek-a-Bangs: His younger self had had messy black hair with a bang hiding his right eye.
  • Pet the Dog:
    • He hugs Trina and gently caresses her hair while she's deactivating in "The Botfighter".
    • After his plan fails, he removes his programming chip, allowing Baymax to save Hiro.
  • A Pupil of Mine, Until He Turned to Evil: He was once Professor Granville's top student, until the accident left him with a tumor that makes him to unable to differentiate right from wrong, and is what drives him off the deep end.
  • Redemption Equals Death: Played With. He doesn't seem to regret the horrible atrocity he was about to commit, but his very last action is to release Baymax from his control to save Hiro, the only person who he feels is his equal, and when Baymax insists on trying to help him, he tells Baymax he doesn't want to be saved, and seems to prefer to die alongside his plan.
  • Red Herring: Given that the left side of his face glows occasionally, the reveal that he got gravelly injured as a kid in an experiment, and the fact that Trina is his robot daughter, it led to a lot of viewers to think he was a robot or a cyborg of some type which on top of it seemed all but confirmed on a sneak peak screenshot of the season's finale. It turns out said glow it's product of a brain tumor caused by his childhood accident which makes him mentally unstable. The picture of a robot is merely a drone he made to distract Hiro.
  • Red Right Hand: The left side of his skull glows purple on occasion, the result of an unusual tumor he gained following a botched attempt to create an energy amplifier in his youth.
  • The Reveal: In "Countdown to Catastrophe", Granville reveals that Obake was once a pupil of hers once known as Bob Aken.
  • Sanity Slippage: Slowly goes through one in "Countdown to Catastrophe". When Globby helps Hiro escape, Obake, who's normally calm and collected, becomes actually furious for the first time and angrily orders to Momakase to bring him back.
  • Sdrawkcab Name: When he goes undercover to steal from Honey Lemon, he gives his name as "Herman Ekabo."
  • Shadow Archetype: Just as Yokai was who Hiro might have become if he had let his desire for revenge against the person who took away someone he dearly loved overtake him, Obake is who Hiro could be if he didn't set limits for himself or care about who gets hurt in his experiments. Obake himself sees the similarities.
  • Skunk Stripe: Has an reddish-orange streak in his otherwise dark hair.
  • Slasher Smile: Gives a terrifying one in "Killer App" before he kidnaps Noodle Burger Boy.
  • Steven Ulysses Perhero: His real name turns out to be Bob Aken.
  • Surrounded by Idiots: Obake is a fairly dangerous and serious villain, while his henchmen, such as Globby and Noodle Burger Boy, are more prone to comedic and idiotic moments. He's clearly irritated by their antics as he tries to work in "Kentucky Kaiju":
    Obake: [rubbing his temples] Stop. Talking.
  • Teen Genius: Was one in his youth, just like Hiro.
  • Theme Naming: Obake is a type of yokai.
  • Truly Single Parent: Built Trina, and she considers him her father. By how he caresses her hair in her debut episode, it's shown that Obake also cares about her the way he would for a daughter.
  • Two-Faced: A downplayed variant. His face looks rather normal, but once he lives a strong emotion like anger or excitement, the left side of his face glows a bright purple. It's due to a Freak Lab Accident in his youth.
  • The Unfettered: Likely at least in part due to both his brain damage and Granville not setting proper limits for him as a student, he has no problem destroying the entire city in order to create a better one.
  • Used to Be a Sweet Kid: The flashbacks involving him in his youth from "Mini-Max" shows that Obake used to be a kid passioned about science and was excited to show his work to his teacher. Professor Granville even talked about him about a kid who wanted to make the world a better place.
  • Tom the Dark Lord: His real name is "Bob Aken". Lampshaded by Fred when he finds out.
  • Uncertain Doom: While he chooses to remain in his collapsing lair, the episode makes his fate nebulous.
  • Vile Villain, Laughable Lackey: He's the serious, creepy Vile Villain in contrast to Globby and Noodle Burger Boy's Laughable Lackeys.
  • Vile Villain, Saccharine Show: Obake, despite his occasional quirks, is a disturbingly dark and wicked villain for such a light-hearted and optimistic series. He's an Omnicidal Maniac who's willing to destroy an entire city and rebuild it to his vision at the cost of the lives of millions of people.
  • Villainous Breakdown: It's more subdued, but he's clearly shocked and subsequently saddened to see his plan come apart, to the point that he doesn't even bother trying to save himself as his lair collapses around him.
  • Villainous BSoD: After Big Hero 6 save the city, he's uncharacteristically heartbroken that everything he'd worked for up to that moment had been for naught, lamenting that he could have built San Fransokyo into something "perfect". Baymax offers to save him, but he refuses and orders him to save Hiro, believing they still could have done great things together. As his lair crumbles around him, Obake quietly sits in his chair and tells Baymax he's satisfied with his care, resigning himself to his fate.
  • Villains Out Shopping: Played with. He goes to Aunt Cass' cafe in "Kentucky Kaiju" because he wants to see how his latest plan is affecting Hiro.
  • Villain Respect: He respects Big Hero 6's intellect and ability to perform heroics, and thus views them as a Worthy Opponent.
    • In the Season 1 finale, when his evil plans are thwarted, he releases Baymax from his control and tells him to go back to Hiro. He could have kept Baymax under his control to stay with him, but it's implied that he respects Big Hero 6 enough (particularly Hiro, Baymax, and indirectly, Tadashi) that he sees their genius minds as worthy enough to entrust the care of the world to and didn't want that to go to waste.
  • Villain Takes an Interest: In Hiro. Some of his plans amount to nothing more than testing the local boy genius, and it's implied he may believe they're Not So Different. The finale reveals he wants to take Hiro in as his own protégé.
  • Villainous Cheekbones: He has high and sharp cheekbones.
  • Visionary Villain: His plan is revealed in the season 1 finale to be recreating the Great Catastrophe and the city's subsequent rebirth.
  • Voice with an Internet Connection: His preferred method of talking is through phones, or hacking into various objects to communicate.
  • We Can Rule Together: He plans to take Hiro in as a student so he could "reach his full potential", and rebuild what's left of San Fransokyo together after Obake succeed in recreating the Great Catastrophe.
  • Xanatos Gambit: After he decides Big Hero 6 are a threat to his plans, Obake enacts several plots against them that seem to fail... but in fact, help him learn more about the heroes.
  • You Have Failed Me: Narrowly averted. When Yama fails to retrieve the alloy for Obake, he barely escapes a murder attempt from him by making an army of Baymax exoskeletons to get the alloy for him. He warns Yama not to deceive him next time.


Globby (Dibs)
Click here  to see his human self.

Voiced by: Andy Richter
Appearances: The Series (debut: "Big Roommates 2")

A purse thief that steals Honey Lemon's chem purse and turns into a goo-based supervillain, making a Heel–Face Turn later on.

  • 10-Minute Retirement: After Globby has difficulty finding work in "Nega-Globby", Honey Lemon and Karmi work together to develop a substance that will remove the goo. After Globby turns back, Dibs confesses to Felony Carl that he actually missed having powers, so he steals Honey Lemon's chem purse and transforms back into Globby, stopping Nega-Globby by swallowing it, with Nega-Globby remaining dormant inside Globby.
  • Abusive Parents: Implied at the end of "Failure Mode".
    Globby: Potential, huh? I told Mom she was wrong about me!
  • Adorkable: Despite being a villain, Globby's clumsy tendencies and him giddily learning to control his powers make him this. After his Heel–Face Turn, Globby's dorkiness is emphasized when he's excited to be part of the good guys and help Big Hero 6 save the city.
  • Appropriated Appelation: Fred was the first to call him Globby, and it stuck. He's actually initially rather aggravated at the name, but goes onto use it anyway.
  • Auto Cannibalism: Once he mastered his shape shifting, one of the first things he does is turn his hand into a bar of chocolate, then ice cream. He even gives Hiro some later on.
  • Baleful Polymorph: Was turned into a gelatinous purple blob. Though he was less horrified than most would be and more annoyed.
  • Blob Monster: After his accident, he turns into an indestructible purple blob that can shapeshift into anything.
  • Butt-Monkey: He can't do his thief stuff right. Becomes even more so after transforming, and even taking a level in badass does not fully cure him from this.
  • Catchphrase: Whenever his poor coordination causes him to trip, splat, or otherwise harm himself, he'll usually utter the phrase "Darn it!" Once he learns how to properly use his powers though, he drops this catch phrase.
  • Character Development: Season 2 shows that he actually has come around to liking his abilities, to the point he actually misses them upon being cured. He's also heavily implied to have finally left his criminal life behind.
  • Co-Dragons: He, along with Noodle Burger Boy, seem to be Obake's top subordinates, and have each acted as The Heavy in his plans to study Big Hero 6.
  • Create Your Own Villain: In "Big Roommates 2", Dibs, who just stole Honey Lemon's purse, discovers Alistair Krei's neurotransmitter headband. Afterwards, he gets covered by exploding purple chemical goo, and Fred calls him "Globby". While on top of a skyscraper, he threatens to throw Krei to the ground below, until Honey Lemon tells him he could use his unique powers to improve his lot in life and make a new start... which backfires when he decides to start a new life of crime as super-villain Globby.
  • Cut Lex Luthor a Check: Played with; as Globby, he has the potential to make a new start by turning his life around and improving his chances... and he uses his neurotransmitter-enhanced abilities to take Krei's wallet, something which he wasn't too successful at as Dibs, being inspired to commit greater crimes as a supervillain.
    • Subverted in "Countdown to Catastrophe" part 3, when he makes his Heel–Face Turn and uses his powers for good to save San Fransokyo.
  • Early-Bird Cameo: Dibs makes a cameo appearance in "Baymax Returns" before his proper debut in the series.
  • Embarrassing Nickname: He hates the name Globby. Naturally, it's a Running Gag that the name spreads like wildfire after Fred coins it, until everyone in the city is using it.
  • Even Evil Has Standards: He's an uncouth weasel and an unabashed thief, but he doesn't want to kill anybody. When he accidentally knocks Krei off a building in his first appearance, he springs into action to save him without even thinking.
    • He even has a Heel–Face Turn in the season 1 finale when he realizes how insane Obake really is.
  • Everything's Better with Dinosaurs: In the Season 1 finale, he shapeshifts into a Tyrannosaurus rex and a Ptero Soarer while wreaking havoc. The kaiju-obsessed Fred wonders why he hasn't done it before.
  • Freudian Excuse: A lot of his villainy seems to come from the fact nobody really took him seriously, with apparently even his mother telling him that he had no potential.
  • From Nobody to Nightmare: Goes from a Harmless Villain to a genuinely dangerous foe... Though he's still a huge Butt-Monkey.
  • Glowing Eyes: Has green glowing eyes. Justified since it's due to the neurotransmitter.
  • Harmless Villain: Was this for a while even when he transformed; it was only after being inspired by Honey Lemon that he starts to leave this trope.
  • The Heavy: The antagonist who ultimately goes up against Big Hero 6 the most throughout the season, and the one who carries out a majority of Obake's plans.
  • Heel–Face Turn: He turns against Obake in "Countdown to Catastrophe" upon learning of his plan to wipe out the city and helps Big Hero 6 save it by stretching his synthetic body out to act as a makeshift dam.
  • Ignored Epiphany: After Globby saves Krei's life, Honey Lemon tells him You Are Better Than You Think, and he decides to give up being a small-time purse snatcher, by deciding to put his new-found powers to use as a supervillain.
  • The Klutz: Before taking a level in badass, Globby has difficulty getting used to his new gelatinous form and is extremely clumsy in the result.
  • Light Is Good: His glob form is a light purple, and he makes a Heel–Face Turn later on.
  • No Sense of Personal Space: He doesn't seem to be aware the concept of personal space exist, which annoys Momakase in "Countdown To Catastrophe".
  • Not-So-Harmless Villain: Once he realizes how his shapeshifting powers work, he actually gives Big Hero 6 a hard time.
  • Only Known by Their Nickname: Other than his alias "Globby", his human name is "Dibs", which is most likely a nickname.
  • Pet the Dog: He give Hiro a chocolate bar before he runs off with the stolen painting.
  • Power Incontinence: Globby had no idea initially on how to use his powers, despite being told that being able to control his powers are as easy as thinking about how he wants to use it. However when he does figure out how to do use it properly...
  • Purple Is Powerful: As the first villain with genuine superpowers, and one with shapeshifting abilities, he has a bright purple body.
  • Real Men Wear Pink: Ever since stealing Honey's chem-purse and Krei's neurotransmitter, Dibs has been permanently mutated into a pinkish-purple bloblike mutant with super powers.
  • Redemption Promotion: In "Countdown To Catastrophe", after deciding to stop Obake from destroying the city, he manages to easily defeat Momakase, and proves instrumental in stopping thousands of people from dying from the tidal wave caused by the mech to cancel out the explosion Obake is trying to create.
  • Secondary Color Nemesis: He has a pair of green eyes to match his purple body. Subverted when he pulls a Heel–Face Turn.
  • Screw This, I'm Outta Here!: After Obake plans to destroy the city, Globby helps Hiro break out of a holding cell and makes a Heel–Face Turn, stopping Momakase by pinning her against the wall with some of his slime.
  • Story-Breaker Power: After learning how to use his abilities, he's consistently one of the most difficult opponents that Big Hero 6 faces, due to the incredibly versatile nature of his abilities that allows him to do almost anything. The fact that he switches sides at the end of Season 1 ends up significantly tipping the odds in the heroes' favor, managing to quickly defeat Momakase, and getting Hiro out of Obake's lair. Unfortunately, this works against him when he's pitted against Nega-Globby, who has the same powers but more mass.
  • Stupid Crooks: His Establishing Character Moment is him trying to steal a purse from an old lady asleep at the bus stop. And failing miserably.
  • Took a Level in Badass: He learns how to better control his powers in "Failure Mode", then trounces Big Hero 6 in their rematch. He's since become one of their toughest opponents.
  • Trademark Favorite Food: Chocolate. Once he discovers how to shapeshift, one of the various objects he creates is chocolate bars.
  • Unskilled, but Strong: He starts out with little experience in using his powers, but his varying chemical makeup makes it nigh-impossible to deal long-term damage to him. This gets downplayed when he learns how to apply his powers to transform into almost anything he can imagine.
  • Vile Villain, Laughable Lackey: The clumsy Laughable Lackey to Obake's creepy Vile Villain.
  • Voluntary Shapeshifting: His powers when fully utilized allow him to become anything he wants. Anything from iron to acid and even icecream with whipped cream.
  • Was Once a Man: Was your average purse thief before the chemicals from Honey Lemon's purse combined with Krei's neurotransmitter transformed him into the Blob Monster Globby.
  • You Are Better Than You Think You Are: When Globby takes Alistair Krei up to the top of the skyscraper, Honey Lemon gives him the following speech:
    Honey Lemon: Listen Globby, I know things look bad now, but there's always a silver lining. You can make this work!
    Bluff Dunder [from his news copter]: The hero says there's a silver lining for the monster. Seems like a stretch... to this reporter.
    Globby: Oh, come on! Nobody believes in me! Why would you? You don't even know me!
    Honey Lemon: Before, you were just a common purse thief. Now, if you dedicate yourself to making the best out of the situation, you can truly be special.
    Globby: Hmm?
    Honey Lemon: No one else has your... abilities.
    Globby: You think?
    Honey Lemon: I know.
    Globby: You're right, this is a new beginning for me.
    Krei: This is very touching, but I want my prototype back!
    • The news camera buzzes by, and as Alistair Krei is falling to the ground after being distracted by the lights, Globby reaches down with his arms and saves Krei, later lampshaded by Honey Lemon and subverted when Globby decides to become a supervillain.
      Krei: This is a little awkward. Thanks... I guess.
      Globby: Thank her, she believed in me. My days of being a loser, small-time purse snatcher are behind me.
      Honey Lemon: That's right! You're better than that!
      Globby: I am! And that's why I'm going to be a supervillain!
    • Later in Part 3 of "Countdown to Catastrophe", Honey's words have a greater long-term effect when he makes a Heel–Face Turn and saves San Fransokyo from an artificial tsunami Obake created to destroy San Fransokyo and rebuild it according to his plans.


    Noodle Burger Boy 

Noodle Burger Boy
"Howdy and hello!"

Voiced by: Lucas Neff
Appearances: The Series (debut: "Killer App")

The fast food mascot of Noodle Burger, who is reprogrammed by Obake to be his henchman.

  • Adorable Evil Minions: To Obake in Season 1.
  • Affably Evil: Even after being reprogrammed by Obake, Noodle Burger Boy retains his jovial personality.
  • Annoying Younger Sibling: Is this to Trina, who although annoyed by his antics, cares about him and refers to him as her "little brother".
  • Big Girl, Little Guy: The Little Guy to Trina's Big Girl.
  • Bottomless Magazines: Of a sort. While on his rampage in "Internabout", Noodle Burger Boy spews out way more ketchup, mustard and pickles than a robot of his size should be capable of holding.
  • Brainwashed and Crazy: Obake reprogrammed him by installing one of his chips, the same kind that Noodle Burger Boy installed into Baymax.
  • Catchphrase: "Howdy and hello!"
  • Chair Reveal: Does a dramatical chair spin in "Obake Yashiki" before greeting the team.
  • Co-Dragons: With Globby. Both work closely with Obake, and have each acted as The Heavy to acquire information on Big Hero 6.
  • Combat Clairvoyance: He can predict every move his opponents make before they make it.
  • Comically Missing the Point: When Trina, in her new mecha body, finds him in "Internabout":
    Noodle Burger Boy: Hi, sis! Something is different. Is it the hair?
    Trina: I cannot believe we're related.
  • Crippling Overspecialization: He's programmed to examine and record behavioral patterns, which makes him very effective at predicting what his opponents can do, which allows him to efficiently counterattack. However, when his opponents switch up their tactics or even outright change their combat style (such as Hiro and Wasabi switching costumes), he struggles to adapt.
  • Cute and Psycho: A cute, cheerful fast food mascot turned evil thanks to Obake.
  • Cute Is Evil: Is an adorable-looking fast food mascot reprogrammed by the Big Bad Obake for nefarious purposes.
  • Evil Laugh: "Hee-hee. Hee-hee."
  • Eye Beams: After being upgraded by Obake, Noodle Burger Boy can shoot lasers from his eyes.
  • Foolish Sibling, Responsible Sibling: The Foolish Sibling to Trina's Responsible Sibling.
  • The Friend Nobody Likes: Obake's inner circle are annoyed by him (and sometimes even Obake himself, who turns him off at one point due to his incessant questions), due to his overly cheery attitude and theme song. Comes to the point they tell him to just shut up when they escape in the Season 1 finale. However, in Season 2 Trina reveals that despite not entirely liking him, she still has a strong attachment to him.
    • Averted when he was a peaceful food service robot, since the Noodle Burger employees are shown to miss him.
  • Giggling Villain: Laughs a creepy robotic "hee-hee".
  • Hostile Animatronics: Becomes this after Obake gets a hold of him.
  • Keet: A villainous example. Even as a supervillain, Noodle Burger Boy maintains his cute, cheerful and excitable personality, which annoys everyone around him.
  • Leitmotif: An entire song, in fact. Since he's a robot, he can play it off a stereo whenever he's doing anything, and he does. Constantly. It even sneaks into the series' score from time to time, most noticeably when he's arming Obake's doomsday device.
  • Made of Iron: A justified, and even literal example; Noodle Burger Boy was built by Krei Tech, and Krei mentions that he was built from military-grade titanium from an abandoned robot soldier project that took too much space. Because of this, Noodle Burger Boy is indestructible and incredibly hard to defeat.
  • Mascot: Of Noodle Burger.
  • Mundane Utility: He was a combat robot prototype turned into a fast food mascot.
  • Perpetual Smiler: Justified since as a mascot his mouth is sticked to his face, but it doesn't make it less disturbing when he's threatening the team or laughing eerily and his face remains the same.
  • Red Eyes, Take Warning: Before shooting lasers from his eyes, they glow an orange-red light.
  • Red Is Violent: Wears red dungarees, and is Brainwashed and Crazy.
  • Siblings in Crime: With Trina as of Season 2.
  • Super-Powered Robot Meter Maids: His durability is due to Krei making him out of a scrapped combat robot prototype.
  • Uncertain Doom: Since he was last seen deactivated by Obake, we don't know if he was destroyed with the base. The Season 2 opener confirms his survival.
  • Vile Villain, Laughable Lackey: The cheerful Laughable Lackey to Obake's creepy Vile Villain.


Click here  to see her updated version
Voiced by: Christy Carlson Romano
Appearances: The Series (debut: "The Bot-Fighter")

A young bot-fighter.

  • Artificial Human: What she turns out to be. She's an overly-realistic teenage girl android created by Obake.
  • Bare Your Midriff: In her first appearance she wears a T-shirt that is too short to cover her belly.
  • Beneath Notice: Hiro never considered her involved with thefts involving Bot-Fights because she always lost. He realizes this was intentional.
  • The Big Gal: After her upgrade.
  • Big Girl, Little Guy: The Big Girl to Noodle Burger Boy's Little Guy.
  • Big Sister Instinct: In "Internabout", Trina spends most of the episode equipping herself to help her "brother", Noodle Burger Boy, even though it's obvious she finds him annoying.
  • Bitch in Sheep's Clothing: Seems to be a nice, friendly girl towards Hiro in her debut episode. Turns out this whole time, she was the one behind the bot thefts, and most likely faked being friends with Hiro as she drops her nice façade when Hiro discovers her. Also important to know Obake programmed her to lure Hiro back into the botfighting world so he'll be out of his way.
  • Brainy Brunette: Enforced. Obake built her to be a competent and highly-realistic android and gave her brown hair.
  • Cool Big Sis: Noodle Burger Boy sees her as such. He even calls her "sis".
  • The Cracker: Can hack into bot-fighter's robots and use them to commit thefts and blame the bot-fighters for it.
  • Daddy's Little Villain: She's a robot made by Obake, and the two have a father-daughter relationship.
  • Deadpan Snarker: Has a sassy, sarcastic streak.
  • Delinquent Hair: Gains a mohawk in Season 2.
  • Even Evil Has Loved Ones: She cares for her "father" Obake and her "little brother" Noodle Burger Boy.
  • Evil Makeover: Although already an antagonist, her new look in Season 2 is much more villainous and anchors her as a threat to Big Hero 6.
  • Fingerless Gloves: Wears these in Season 1 as part of her "teen rebel" look.
  • Foolish Sibling, Responsible Sibling: The Responsible Sibling to Noodle Burger Boy's Foolish Sibling.
  • Girliness Upgrade: Inverted. Her new design in Season 2 looks far more tomboy-ish compared to her original Season 1 look.
  • Girly Girl with a Tomboy Streak: Though it might be how Obake programmed her, Trina wears a pink shirt, jeans with stars and has long hair, while being simultaneously into bot-fighting and has an overall "teen rebel" look and personality. By Season 2, she goes more into tomboy territory when she upgrades herself and cuts her hair.
  • Ink-Suit Actor: She does bear some similarities to her voice actress, Christy Carlson Romano.
  • Innocent Blue Eyes: Subverted. Seems to hint her friendly nature to Hiro at first, but turns out to be a case of Icy Blue Eyes as well as hinting her being Obake's "daughter", since Obake has Icy Blue Eyes as well.
  • Little Miss Con Artist: Similarly to Hiro in the movie, she pretended to lose in all her bot-fights. This permitted her to hack into her opponents' robots without them knowing and frame them for her thefts.
  • Losing Your Head:When Hiro is taken to Obake's lair he sees her head on a table.
    • Becomes a Running Gag in "Internabout", where she constantly loses her head. It pushes her to upgrade herself a new body.
  • Manipulative Bitch: Implied to have faked her friendship with Hiro and used his help to commit more crimes. Also her goal from the start was to make Hiro go back to bot-fighting in order for him to stay away from Obake's path.
  • Mini-Mecha: Her new body in Season 2 definitely counts as this.
  • Nice Hat: Wears blue and purple beanies in Season 1 as part of her "teen rebel" look.
  • Obfuscating Stupidity: Just like Hiro in the movie, she pretends to be a noobie at botfighting only to fool her opponents and hack their robots.
  • Pink Means Feminine: Wears a pink shirt in her initial look.
  • Purple Is Powerful: Her mecha body has different purple highlights, and makes her a much more dangerous foe than she initially was with her android body.
  • Rapunzel Hair: Has long loose hair reaching the bottom of her back. In Season 2, she cuts them into a mowhawk, stating "they got in the way".
  • Robotic Reveal: It turns out that she's a robot made by Obake. She considers him her father.
  • Siblings in Crime: With Noodle Burger Boy as of Season 2.
  • Skunk Stripe: Has two white streaks in her hair.
  • Teen Genius: Is very skilled with building robots. Justified, since Obake programs her as such.
  • Uncertain Doom: She is not seen again before Obake's base is destroyed. She returns in the Season 2 opener.
  • Villainous Crush: She appears to have one for Hiro, despite being an android and Hiro being human.
  • Wham Shot: In "The Botfighter", seeing her face open and revealing robotic insides.

    Buddy Guards 

Buddy Guards
Click here  to see their appearance before the glitch
Dumpling form

A brand of drone robots created by Krei Tech that was made for safety purposes. A glitch in their systems causes them to go haywire and attack everything it sees. It eventually becomes Noodle Burger Boy's minions, and overall work for Obake.

  • Adorable Evil Minions: Once Noodle Burger Boy makes them turn into smiley-faces dumplings.
  • Attack Drone: While built as Surveillance Drones, they turn into this due to a fabrication malfunction and after Obake builds them for Noodle Burger Boy.
  • Brainwashed and Crazy: After Fred dumps juice on one, it attacks the gang. It's because they have a fabrication malfunction that once triggered, their friendly programming goes out the window and they try to neutralize everything they see.
  • Cute Machines: Before their glitch, they're actually quite adorable. Taken Up to Eleven when Noodle Burger Boy makes them turn into smiling dumplings.
  • Cyber Cyclops: Are attack drones with only one eye.
  • Eye Beams: They can shoot non-lethal lasers from their eye.
  • Inescapable Net: Can trap threats into nets, or throw bolas to restrain them.
  • Invisibility: They can turn invisible, which makes it impossible for the team to know when they'll strike.
  • Killer Robot: Downplayed. While not designed to kill people, it was programmed to neutralize what they see as "threats". Thing is, after it glitches and once Obake takes control of them, they see everything as a threat. Especially Big Hero 6...
  • Light Is Not Good: They're white-colored, but once they malfunction, they attack everything they see.
  • Mecha-Mooks: Act as henchmen to Noodle Burger Boy, and overall to Obake, as seen in "Obake Yashiki" when they're building a machine for him, and are competent enough that Big Hero 6 always struggle against them.
  • Punny Name: Their names is a pun between "buddy" and "bodyguard".
  • Purple Is Powerful: After they turn evil, their secondary cyan lighting turns purple.
  • Red Eyes, Take Warning: Once their programming goes haywire, their green eye turns red before they attack everything they can see.
  • Shapeshifting: Thanks to Mel's Flexible Display technology, they can turn into about quite everything, from giant Krei heads to adorable dumplings.


Sycorax and Associates

    Liv Amara 

Liv Amara
"At Sycorax, we believe in progress at any cost."

Voiced by: Mara Wilson
Appearances: The Series (debut: "Big Problem")

A self-made billionaire whose company, Sycorax, specializes in bio-technology. The main antagonist of Season 2.

  • Always Someone Better: Krei refuses to believe that she's better than him in every way.
  • Ambiguously Evil: While it's clear that Liv is a cruel and vindictive sociopath, the revelation that she wasn't the real Liv all along brings into mind just how much is the real Liv even aware of, much less involved, in the actions of the fake one..
  • Arc Villain: For the "City of Monsters" arc of Season 2.
  • Beauty Is Bad: Is an attractive 23 year old woman, and the main antagonist of the second season.
  • Beneath the Mask: Underneath her kind, likable facade is a sociopath who seems to take pleasure in her ruthless acts of villainy.
  • Benevolent Boss: She believes in treating her employees well, unlike Krei, who doesn't give good pay and can be an ass to his workers.
  • Big Bad: Of Season 2's "City Of Monsters" arc.
  • Bitch in Sheep's Clothing: She appears to be a nice, charismatic person. Beneath this front, she is eerily ruthless and amoral, having no qualms with experimenting on human beings and turning them into monsters.
  • Blackmail:
    • As "Prey Date" reveals, Liv was the one who turned Orso Knox into a monster in the first place back in "Big Problem", and blackmails him into funding her unless her wants to be turned back into his monster form.
    • In "Something's Fishy", she bails out High Voltage out of jail, but when they turn down the occasion to work with her since they want a normal life, Liv threatens to call the police on them and states no one will believe criminals like High Voltage she bailed them out, since she gave the police new K-9 units and is overall loved and seen as an angel by the public, leaving them no choice but to work for her.
  • Contralto of Danger: Has a low-pitched, mellow voice tone for a 23 year old, hinting at her evil nature.
  • Contrasting Sequel Antagonist: Obake stayed out of the spotlight, and predominantly utilised robotics in his schemes. Liv Amara, however, is a businesswoman who is beloved by the public, and heavily prefers bio-engineering. Obake is mentally ill as a result of his growing brain tumour, but all the while refuses to have it treated, even seeing it as a blessing. The fake Liv on the other hand goes to great lengths to treat the real Liv's illness, and is what primarily drives her villainous actions. Obake is Affably Evil who is genuinely civil and polite to both his subordinates and enemies, and even shows a display of empathy towards his own creation Trina and treats her like a daughter. Liv is Faux Affably Evil whose relationships with others a merely a means to an end, with even her creation/assistant Chris being seen more of a pet than an actual person. The difference goes all the way down to how they treat their younger counterparts: Hiro and Karmi respectively. While Obake and Hiro are enemies, the former genuinely respects the latter and wishes for Hiro to be his protégé, and in his final moments goes his way to save Hiro's life. Karmi admires Liv and does become her protégée, but Liv is nothing more than a False Friend who has no qualms trying to have Karmi killed when she interferes with her plans.
  • Corrupt Corporate Executive: As she herself puts it, Sycorax is dedicated to progress "by any means necessary", which includes creating monsters out of humans through illegal experimentation. She is also just fine with aligning herself with criminals like Momakase.
  • Even Evil Has Loved Ones: Being the narcissist that she is, it's no surprise that she only cares for the real Liv.
  • Evil All Along: Is introduced in "Big Problem" as a kind, charismatic business woman. Season 2 reveals she's a sociopath and a Hidden Agenda Villain.
  • Evilutionary Biologist: She intends to "improve on Mother Nature's work", which means giving biological enhancements to people that turns them into powerful monsters.
  • Evil Wears Black: Wore a black gown in her debut episode. Can count as foreshadowing since it was before her villain reveal.
  • False Friend: Is this to Karmi, who has no idea of Liv's true colors and sees her as her "bff".
  • Finger-Tenting: Pictured above, as her villainous side is revealed to the audience in "Seventh Wheel".
  • Foil:
    • To Krei.
    • To Karmi.
      • Both are two-faced in different ways. Karmi's "nice girl" act was only in front of Granville to annoy Hiro, and dropped it by "Failure Mode". As for Liv, she gives herself a nice mask in public only to hide how monstrous she truly is. Also, Character Development turns Karmi into a Jerk with a Heart of Gold, while Liv becomes more immoral and villainous as episodes go on.
      • Both are passionate about their scientific work and would rather not interact with people if they aren't interested in that same passion. While two biologists, Karmi has a strong sense of moral by how she was ready to work into a basement with a feral monster Knox loose into it to be sure he turns back into a human, and also by how she cares about Hiro's well-being despite not getting along with him. As for Liv, she has no sense of morals, doesn't care about the consequences of her actions, and is even thrilled to commit them.
      • They also seem to be a bit oblivious about how their male counterpart feels about them, with Amara being unaware of Krei's envy of her and Karmi being unaware that Hiro, a boy she sees as her rival, is the hero she crushes on. Both Krei and Hiro also express immaturity when talking about their female counterparts as well.
  • Freudian Excuse: The real Liv Amara is an Ill Girl, so she's naturally dispositioned. As a result, she wants to "improve on Mother Nature" by mutating people into monsters for a currently unspecified reason, likely relating to her health.
  • Granola Girl: A rare, surprising villainous exemple. She sees herself as a "Mother Nature protégée", uses ecologic technology and Sycorax contains lots of bio food. Yet, she's a villain. Though she exploits this trope in order to be seen as a good person and have no one doubts her plan.
  • Hair of Gold, Heart of Gold: Exploited by Liv. Liv is a blonde-haired woman who gives herself a "Mother Nature"-loving façade, and is seen as a kind, charismatic individual by the public. Behind closed doors, she's a Bitch in Sheep's Clothing and a ruthless sociopath.
  • Hate Sink: Is a manipulative Corrupt Corporate Executive who turns people into monsters often without their consent, blackmails people into supporting her, and treats her assistant like a pet.
  • Hot Scientist: An attractive Mad Scientist.
  • Hidden Agenda Villain: We have no idea why Liv does illegal mutations on those who fund her, and what is has to do with the real Liv Amara who's in stasis.
  • Ill Girl: The real Liv Amara is seriously ill (it is implied she has a rare disorder) and put herself into stasis while the Liv impostor tries to continue her endeavors.
  • Kick the Dog: When she comes to visit SFIT, she's eager to ask about Baymax to Hiro, but as soon as Hiro clarifies that Tadashi was the one who created Baymax, she immediately loses interest despite Hiro stating he's added additional features to Baymax and still being able to answer her questions.
    • She turned Orso Knox into a monster, then helped cure him (after months of deliberate delays) under the condition that he continually invest in Sycorax or else she will turn him right back to his monstrous state.
  • Know When To Fold Them: When she tried to create Nega-Globby, but it proved to be unstable, Liv decides it's not worth the trouble trying to get it back under control.
  • Mad Scientist: Uses her biotechnology skills for human transmutation and other morally questionable endeavors.
  • Manipulative Bitch: As Season 2 shows, she could give Obake a run for his money in terms of manipulative villainy.
  • Meaningful Name: "Amara" means "bitter" in Italian, and "grace" in African. Both fits her a lot, since Liv gives herself a gracious face, only to be a bitter, immoral person underneath.
  • Pet the Dog:
    • She kindly waves to Krei while in the middle of chatting to a bunch of other socialites.
    • She is affectionate towards her assistant Chris. However, this is downplayed in that she treats him as a pet rather than a person.
  • Psychopathic Woman Child: Implied. Even with her true colors being revealed, she's shown to be thrilled over her plans similar to an excited teenage girl. It's shown when she's alone with Orso Knox and High Voltage.
  • Psychotic Smirk: Does one of these at least once an episode in Season 2.
  • Red Is Violent: Liv wears a red shirt and pencil skirt. She's actually an amoral sociopath that doesn't care what mayhem she causes or who she hurts in the process.
  • Ship Tease: From Krei, maybe. At her gala for SFIT's new Bio-Tech building, Krei complains to Hiro that Amara is a rival who is somehow better than he is, even if she may be "brilliant and beautiful and generous", but then she notices him looking at her from the other side of the room and waves at him, to which he awkwardly waves back. Hiro seems to see it.
  • Smug Snake: Is completely confident in herself and her plans, to a point of being incapable of seeing why Big Hero 6 always seem to foil her plans.
  • The Sociopath: Arguably even worse than Obake. Liv is a manipulative Bitch in Sheep's Clothing who commits horrible actions and shows no remorse over them.
  • Tuckerization: Maybe. Her surname is Amara, whereas her voice actress's first name is Mara.
  • Unknown Rival: She isn’t aware that Krei is jealous of her.
  • Vile Villain, Saccharine Show: While apparently not the Omnicidal Maniac like Obake was, Liv's cruel actions have hurt many people on a much more personal level. As such, she definitely stands out as a disturbingly dark and wicked villain in such a light-hearted and optimistic series.
  • Villain with Good Publicity: Liv is well-liked and respected by the people, but no one knows about her shady way of recruiting investors through unsavory means.
  • With Friends Like These...: Is obviously manipulating the naive Karmi and tried to have her killed after Karmi sneaked into Sub-Level 9 with Hiro and found a cure for Knox. Karmi has no idea of this.
  • Would Hurt a Child: Has no problem leaving Hiro and Karmi to a feral Orso Knox's mercy (whom she herself freed from his cell) after Karmi interfered with her plans by sneaking into Sub-Level 9.
  • Xanatos Gambit: Even when Big Hero 6 catches on to her true nature and that she's responsible for the monster mutations, they have no choice but to go to her for help so she can give them the cure as the alternative is letting a monster go loose in San Fransokyo and being seen more as vigilantes than heroes. As a result, Liv gets free PR and more support while she's allowed to continue her schemes.
  • Younger Than They Look: Though Liv has a deep sultry voice, acts very mature and has her own company, sometimes it's easy to forget she's only 23 years old.



Voiced by: Ben Feldman
Appearances: The Series (debut: "Internabout")

Liv Amara's assistant, or as he prefers to be called, her "Chris-sistant".

  • Affably Evil: Is honestly a pretty nice guy, even if he is working for Liv Amara.
  • Affectionate Nickname: He likes it when Amara calls him her "Chris-sistant".
  • Ambiguously Brown: Has a light brown skin, but we have no clue of what his ethnicity could be.
  • Ambiguously Gay: Is quite flirty with Wasabi, as seen in "Internabout" and "Prey Date".
  • Artificial Human: Was created by Amara to be her perfect assistant and bodyguard.
  • Battle Butler: He is Liv's assistant and has some modifications that allow him to lunge and punch straight through an SFIT security drone unharmed.
  • Deadpan Snarker: Can be quite the snarker towards Liv herself.
  • The Dragon: To Liv.
  • Even the Guys Want Him: In addition to Honey Lemon, both Fred and Wasabi express how extraordinarily attractive he is (with only GoGo gives him a slightly disinterested "eh"). Even Ned Ludd constantly refers to him as "handsome".
  • Fun Personified: Sure, he's evil, but that doesn't change just how darn kind and excitable he is.
  • Human Pet: Acts like Liv's human dog. Liv states she named him, enforcing his status as an Artificial Human created by her.
  • Literal-Minded: When Ned Ludd asks him where he comes from, Chris answers "the world's most advanced genetic lab". He doesn't say he works for Sycorax, he says that because he literally comes from there, as he's an Artificial Human created by Liv.
  • Mr. Fanservice: Wears tight clothes that enhances his symmetrical build, and has his fair share of admirers.
  • Nice Guy: Despite being Liv's right-hand man and following her orders, he doesn't seem to be actually mean; he's friendly to everyone (in a genuine way, compared to Liv), proposes food he cooked himself (even when alone with Nega-Globby) and refers to Karmi as an "ambitious and adorable intern" to Liv in a private conversation with her.
  • The Nose Knows: In "Muira-Horror!", Chris uses his enhanced sense of smell to track down a bear and steal his DNA for Liv.

  • Supreme Chef: Makes excellent sushis, and can make delicious cupcakes using gold sprinkles.
  • Trademark Favorite Food: Really likes sushis.

    High Voltage 

High Voltage (Barb and Juniper)
Barb (left) and Juniper (right) (Click here  to see their mutant form)

Voiced by: Katy Mixon (Barb), Sophie Reynolds (Juniper)
Appearances: The Series (debut: "Issue 188")

A mother-daughter team of electricity/music-themed criminals.

  • '80s Hair: Both have voluminized, blonde bleached hair with colors in their bangs (purple for Juniper, pink for Barb), to go with their '80's aesthetic.
  • Action Mom: Barb is a villainous example.
  • Affectionate Nickname: Barb sometimes calls her daughter "Juni".
  • Acrofatic: Barb is a chubby woman capable of of doing flips and backflips just as easily as her daughter.
  • Animalistic Abomination: They have completely transformed into them by the end of their third appearance.
  • Attention Whores: High Voltage wants attention just as much as money, if not more.
  • Ax-Crazy: Their mutation causes them to lose about all of the sanity and morality they still had.
  • Big Beautiful Woman: Barb. Not once is her weight/appearance mocked, and she obviously has her admirers.
  • Black Eyes of Crazy: Their mutated eel forms have these.
  • Bratty Teenage Daughter: Juniper, by moments. She craves attention and even leaves her mother after she is caught by Big Hero 6 in their debut episode, but after her reconciliation with her mother in "Big Hero 7", she seems to have dropped this.
  • Calling Parents by Their Name: When they are feuding in "Big Hero 7", Juniper calls her mother "Barb" out of anger at one point. Once they reconcile by the end of the episode, Juniper goes back to calling her "mama" in future episodes.
  • Cut Lex Luthor a Check: Played straight and even lampshaded by Wasabi and Honey Lemon. Barb and Juniper are genuinely good performers, to a point where they even have crowds of people cheering for them as they commit crimes, well... mostly Juniper. Wasabi and Honey Lemon, in an attempt to get them to give up their life of crime, point out that if the duo simply auditioned for a talent scout, they could easily obtain fame and fortune through legitimate means. But due to some twisted form of pride, Barb and Juniper believe auditioning is beneath them, but stealing is alright.
  • Dance Battler: Both of them channel their electrical attacks through dance moves.
  • Dark Action Girls: Both are capable fighters and are the first female villains to be introduced to the series.
  • Disappeared Dad: No indication of Barb's husband/Juniper's father's status.
  • Driven to Villainy: Their mutation into eel-like creatures causes them to have a Villainous Breakdown, and return to villainy.
  • Dumb Muscle: Said to be such by Mr. Sparkles himself among the Sycorax team.
  • Even Bad Women Love Their Mamas: Despite the few differences they may have by moments, Juniper truly loves her mother.
  • Even Evil Has Loved Ones: Despite being criminals, they greatly care about one another.
  • Evil Feels Good: They come to this conclusion after their mutation causes them to realize just how fun it is being criminals.
  • Excessive Evil Eyeshadow: Since both have an '80's aesthetic, they have bright light blue eyeshadow, completed with a lightning for Barb. Juniper's isn't just on her lid, it's around her whole eye.
  • Expy: The duo seem to be a Distaff Counterpart of the father-son villains, Señor Senior Sr. and Señor Senior Jr. from the creators' previous series.
  • Fat and Skinny: Barb and Juniper, respectively.
  • Forced into Evil: Thanks to Liv.
  • Friendly Enemy: They actually get along pretty decently with Wasabi, even explaining how they got so good at dancing to him.
  • It's All About Me:
    • Juniper was willing to abandon her own mother when Barb is caught by Big Hero 6, however she didn't get far, as Juniper is shortly subdued by Baymax.
    • Barb. When a crowd cheers Juniper's name, she adds "And Barb!" And when Juniper points out how another crowd is cheering for her, Barb insists that they're cheering for both of them.
  • Heel–Face Door-Slam: Attempted to pull one in Season 2, only to be pulled back into crime by Liv...And then realize themselves that they could never really go straight due to how fun villainy is.
    • Reality Ensues: And besides, turns out it's difficult for recently escaped criminals to just put off crime all together without time.
  • Hidden Depths: Barb actually has quite the amazing singing voice.
  • Horror Hunger: High Voltage get a craving for fish, so they stop a seafood truck and eat the shipment, without cooking it.
  • Leitmotif: They have one that, given their gimmick, is as likely to be literally playing in-universe.
  • Lethal Joke Character: Their gimmick, appearance, and personalities are pretty goofy. However, they are capable of defeating and escaping from Big Hero 6 two times during their debut episode. This is lampshaded by Fred, who points out that it is not uncommon for heroes to underestimate and be defeated by seemingly silly villains.
  • Little Miss Badass: Juniper. She's a teen, and an acrobatic dancer and fighter.
  • Logical Weakness: Their attacks don't work on anything that can insulate electricity. Also, taking out their energy orb would get rid of their electrical powers.
  • Mama Bear: Barb promptly hands Richardson Mole's butt to him after he insults Juniper's dancing in "Big Hero 7".
  • Meaningful Name:
    • Barb is a common nickname for the biblical name "Barbara". The saint wearing her name is the protector of fire and lightning. Barb uses electricity powers and bolts of lightnings as a supervillain.
      • "Barbara" also means "strange", which makes sense considering High Voltage is a more comedic pair of villains.
    • Juniper means "young", "youth-producing". She's the Younger and Hipper part of the duo.
  • Mini Dress Of Power: Both wear black mini-dresses over bright-colored leggings.
  • Musical Assassin: They play music and perform dances while committing crime.
  • My Beloved Smother: Barb, to Juniper. She seems to have toned this down after "Big Hero 7".
  • Pride: The two really love attention. They even believe auditioning is beneath them since they already see themselves as "stars".
  • Psycho Electric Eel: In Season 2, they got the ability to make their own electricity with some Bio-Augmentation using electric eel DNA. This eventually resulted in them turning into eel-like Fish People, and then barely-human eel creatures.
  • Screw This, I'm Outta Here!: In "Issue 188", Juniper tries to escape and leaves Barb to be arrested after she is caught by Honey's chem-ball. She doesn't go far and is stopped by Baymax.
    • In "Something's Fishy", they try this when Liv wants them to work for her while all they want is a normal life. Unfortunately, Liv blackmails them, leaving them no choice but to give in.
  • She-Fu: Uses a lot of acrobatics in their fighting style.
  • Shock and Awe: They can use electrical attacks thanks to an energy orb floating above their heads.
  • Stage Mom: Barb acts as this to Juniper. Downplayed as while some of her lines pushes Juniper to get their dance moves right, Barb cares a lot about her daughter and loves to dance with her while they commit crimes.
  • The Unintelligible: As eel monsters, they can only communicate in screeches and hisses.
  • Villain Song: Barb has her own one in "Something's Fishy" called "We're Gonna Do Good". Ironically about turning good, while a few instants later, they go back to villainy.
  • Was Once a Man: In "Something's Fishy" they are transformed into eel monsters by Liv.
  • You Gotta Have Blue Hair: Their half-human half-eel form turns their blonde hair blue. They seem to keep these even as full-eel mutants.
  • Younger and Hipper: In-Universe, people seem to prefer Juniper over Barb.

    Mr. Sparkles 

Mr. Sparkles
Click here  to see his mutant form

Voiced by: Patton Oswalt
Appearances: The Series (debut: "Mr. Sparkles Loses His Sparkle")

An insane game show host.

  • Adaptation Dye-Job: A meta exemple. In the concept art of the movie, Mr. Sparkles is shown to have light blonde hair. Here in the series, he has pink hair.
  • Anime Hair: His mutated hair is long and spiked up.
  • Ascended Extra: He has only one voiced appearance in Season 1, and doesn't bother the heroes beyond that one despite being in the opening. In Season 2, he becomes part of Liv Amara's team of villains, which gets him a lot more screentime.
  • Attention Whore: Tells a contestant that he called onstage to get out of his light, and this was before Mochi's video took away his internet fame.
  • Ax-Crazy: Part of his new obstacle course has a giant blender, which GoGo almost falls into.
  • Bald of Evil: His pink hair is actually a toupee, and Mr. Sparkles is bald underneath. Though as of Season 2, he grows green hair after his mutation.
  • The Beastmaster: Liv engineers for him a species of creatures that can become giant beasts he can control and sense through.
  • Berserk Button: Having the attention taken away from him proves itself to be a major one.
    Mr. Sparkles: [growls] No one can take away Mr. Sparkles' sparkle! No one!
  • Cloud Cuckoo Lander: Surprisingly, a villainous example. His games uses a lot of bizarre aspects, and uses weird gadgets as well (ex: a chicken airship that drops egg bombs, and that's one of many weird things...)
  • Creepy Blue Eyes: Has blue eyes, and is an insane, bizarre individual.
  • Disproportionate Retribution: A cat took away all the attention away from you? Kidnap it and threaten to blast it into outer space unless someone can rescue it from your obstacle course.
  • The Dragon: He has this role to Liv Amara, who acts as the de facto leader of the monsters crafted by Sycorax. With him being more of a public face, no one will suspect that Liv is behind his activities.
  • Evil Is Hammy: Has quite the flamboyant personality, with Evil Laugh included.
  • Expy: Is this to Arcade, a villain with a game show host personality who forces people into what is essentially a deadly obstacle course.
  • Faux Affably Evil: He's a flamboyant and seemingly cheerful game show host, but is also quick to insult the contestants when they fail his challenges. He's also willing to commit crimes just to seek Fame Through Infamy.
  • Glowing Eyes of Doom: After Liv mutates him, his eyes glow a bright green when he gains control over the Mayoi.
  • Green and Mean: After his bio-augmentation, he gains green skin and hair.
  • Green-Eyed Monster: Exaggerated. He's jealous of a cat for stealing his fame.
  • I Lied: Even though he says he will let Mochi go if anyone can finish his obstacle course; after GoGo won the challenge, he still launches Mochi into space.
  • Karma Houdini: Zigzagged. He doesn't get into any actual trouble for kidnapping Mochi or putting his challengers through a deadly obstacle challenge but he has his own wanted poster, which in his eyes, means that he's famous again so he takes it as a good thing. Borders on Karma Houdini Warranty.
  • Kick the Dog: More like "Kick The Cat". He kidnaps Mochi and threatens to send him to space unless someone succeeds his obstacle cours. When GoGo succeeds... he blasts Mochi to space anyway.
  • Laughing Mad: The Evil Laugh he does on occasion showcases how mentally unstable he is.
  • Moral Myopia: He claims having having his fame stolen by a cat is "not fair", yet he rigged his obstacle course with various hidden traps so it would be all but impossible to win.
  • The Napoleon: A short, hot-tempered Psychopathic Manchild.
  • Plant Person: He is genetically engineered to become part-plant which gives him control over the Mayoi.
  • Psychopathic Manchild: Felony Carl describes him as an "emotionally unstable man-boy" in "The Fate of the Roommates".
  • Small Name, Big Ego: Pulls the "Don't you know who I am?" statement after Mochi is more popular than he.
  • Villain Team-Up: Teams up with Yama in "The Fate Of The Roommates". Subverted as he breaks it off and ends up backstabbing Yama and leaving him to be caught, though.
    • Played straight by the end of the episode where he affiliates himself with Liv Amara.
  • You Gotta Have Blue Hair: Has pink hair, apparently a toupee. He grows green hair when he activates the powers Liv gave him.
  • 0% Approval Rating: The people watching the show seem way more interested in the absurd challenges than its loud host. Noticeably even before Mochi becomes famous, nobody seems terribly interested in Mr. Sparkles’ antics.

    Orso Knox 

Orso Knox
Click here  to see his human self

Voiced by: Fred Tatasciore
Appearances: The Series (debut: "Big Problem")

A wealthy man turned into a monster in mysterious circumstances.

  • And I Must Scream: It's heavily implied that Knox is stuck in his savage monster form and a part of him is desperately trying to call for help.
  • Big Eater: Invoked by Hiro in "Prey Date". He actually never set to hurt anyone. He was simply hungry.
  • Dark Is Not Evil: Even as an unstable monster, Orso Knox doesn't want to hurt anybody purposefully. He's simply hungry and slowly loses himself to his animal instincts.
  • Forced into Evil: "Prey Date" reveals Orso Knox is far from being a villain. He was turned into an unstable monster by Sycorax, probably part of an experiment, and after Karmi helps turning him back into a human, Knox gets blackmailed by Liv into funding her company and give her good publicity or she'll turn him back into his monster form.
  • Ironic Name: Orso means "bear". Though he has no resemblance to a bear, his name means a ferocious beast... just like him.
  • The Mind Is a Plaything of the Body: The more time he spends in monster form, the more savage he becomes.
  • Mix-and-Match Critters: His monster form looks like a cross between a whale, a dinosaur and a human.
  • Non-Malicious Monster: Despite his vicious looks, he saves Hiro twice in a row.
  • Old Friend: Of the Frederickson family. Mrs. Frederickson greatly worries about his condition.
  • The Unintelligible: As of "Prey Date", Knox was kept for so long in his monster state he lost the ability to speak and can only growl, roar and grumble.
  • Speaks in Shout-Outs: Knox is a fan of Shakespeare. As a monster, he communicates entirely in Shakespeare quotes.
  • Was Once a Man: He turned into a monster by Liv Amara to ransom his humanity back to him.
  • Wouldn't Hurt a Child: Even if he's a feral monster, he never tries to actually harm Hiro. This shows he still has some of his humanity left into him. "Prey Date" implies he was actually trying to save Hiro from Liv's basement, thinking she'd mutate him as well.


Voiced by: Dee Bradley Baker
Appearances: The Series (debut: "Nega-Globby")

  • The Assimilator: Initially a small blob, it absorbed matter into itself to increase its size. It also absorbed an eye from a creature contained within Liv's lab.
  • Ax-Crazy: Liv's experiment on him made him too unstable, and once he escapes Sycorax, he destroys everything that gets in his way.
  • Black Eyes of Crazy: Has a black scelera behind his red eye.
  • Blob Monster: Just like Globby himself, he's entirely made of goo.
  • Cyclops: Is a Blob Monster with one, single red eye.
  • Dark Is Evil: Is a dark bluish-purple color, in contrast to Globby's much lighter purple color.
  • Evil Counterpart: To Globby.
  • Evil Is Bigger: Stands much taller than Globby, and this extends to all of its forms as well.
  • It Can Think: It's suggested to be smarter than it looks in spite of its animalistic rampage, due to knowing how to use all of Globby's abilities, and demonstrating strategic capability in its fight with Big Hero 6 and Globby.
  • The Juggernaut: None of the team even made it flinch, to a point where he pretty easily could have destroyed the city had Globby not intervened.
  • Nigh-Invulnerability: Nothing Big Hero 6 throws at him actually works to stop him, which makes sense due to him being made out an indestructible substance.
  • Not Quite Dead: Globby eats Nega-Globby, but the ending of the episode shows that Nega-Globby still exists inside of him.
  • Purple Is Powerful: Is a dark shade of purple, and a dangerous foe.
  • Red Eyes, Take Warning: Has only one red eye, and is a dangerous monster that destroys everything he sees. Completed with Black Eye Of Crazy.
  • The Unintelligible: Contrary to Globby who is half-human, half Blob Monster, Nega-Globby is simply derived from Globby's gelatinous consistency, thus he only communicates in growls and roars.
  • Unstoppable Rage: From the second Liv tampers with it, it becomes incredibly angry, rampaging and destroying basically everything in sight from that point forward.


Voiced by: Dee Bradley Baker
Appearances: The Series (debut: "Something Fluffy")

A bunch of cute creatures that mysteriously starts appearing around the city.

  • Adorable Evil Minions: Once Mr. Sparkles gets the power to control them, they become this to him.
  • Big Eyes, Little Eyes: Have quite large eyes, emphasizing their cute appearance.
  • Cute Is Evil: Was created by Liv Amara as part of her evil plans and are extremely adorable. Subverted as when not under Mr. Sparkles' control, they're more Punch Clock Villains than anything.
  • Cuteness Proximity: No one can resist their cuteness. Not even GoGo or Professor Granville. Only Hiro doesn't let their cute appearance fool him.
  • Expy: Let's see... adorable creatures that has multiple growing phases and can only say the name of their species. Where have we heard of this before?
  • Gentle Giant: Even when they become gigantic, they maintain their puppy-like personality and are still affectionate. That's as long as they're not under Mr. Sparkles' control, that is...
  • Giant Mook: Engineered to be this for Mr. Sparkles.
  • Green and Mean: Zig-zagged. Although created for nefarious purposes, they're pretty much inoffensive unless they're put under Mr. Sparkles' control.
  • Meaningful Name: Mayoi written in kanji can mean doubt, hesitation or bewilderment while katakana can refer to lost. They were engineered to sow doubt of Liv's culpability in the monsters, people are hesitant to believe they're a threat, Hiro is confused on how they could even be at first in spite of his suspicions and they ultimately end up escaping with Mr. Sparkles in the end.
  • Miracle-Gro Monster: Because they can eat regular food as well as photosynthesize they grow massive in a short amount of time.
  • Non-Malicious Monster: The Mayoi display no real aggression and are very friendly in their natural state, even when they grow to large sizes, allowing Big hero 6 to easily herd them. Unfortunately, this only lasts until Mr. Sparkles takes direct control of them.
  • One-Word Vocabulary: "Mayoi!"
  • Pintsized Powerhouse: When working together, they're capable of throwing shipping containers!
  • Planimal: More plant than animal.
  • Pokémon Speak: They can only say "Mayoi"
  • Punch-Clock Villain: Don't have any actual villainous intent, as shown from their friendly interactions with just about all of San Fransokyo. In fact, they're only really on the villain's side at all because of Liv Amara and Mr. Sparkles' control over them.
  • Ridiculously Cute Critter: Nearly everyone in San Fransokyo (even GoGo and Professor Granville) thinks of them as adorable.


Click here  to see Bessie as a meteor

Appearances: The Series (debut: "Muirahara Woods" (as a meteor), "Lie Detector" (as a monster))

A meteor owned by Ned Ludd whose magnetic field causes electronic devices to malfunction. In Season 2, Liv Amara steals and mutates it with bear DNA, creating a dangerous monster with electromagnetic capacities.

  • Ax-Crazy: Since it's part-bear, Bessie is extremely unstable and aggressive.
  • Bears Are Bad News: Liv mixes bear DNA (which she gets from Chris fighting one and getting some of its fur) and combines it with Bessie to create a meteorite-bear hybrid to get the gold she needs. The combination of the bear's savage nature and Bessie's Walking Techbane properties make it a formidable opponent for Big Hero 6.
  • Black Eyes of Crazy: Bessie's scelera is black, emphasizing her shining yellow eyes and violent nature.
  • Breath Weapon: Bessie has the ability to fire electromagnetic beams from her mouth.
  • The Brute: To Liv.
  • Companion Cube: As a meteor, Bessie is this to Ned. He sweet talks her and becomes aggressive when someone is too near her.
  • Eye Lights Out: Happens when Baymax sucker-punches Bessie. Unfortunately, she gets back up a few moments later.
  • Glowing Eyes of Doom: Has bright, yellow shining eyes.
  • Gold Fever: A variant. Liv created the Bessie monster to steal the gold she needs in order to cure the real Liv in stasis from a rare disease.
  • Green and Mean: As a bear monster, Bessie keeps her green color and glow.
  • Hybrid Monster: Liv combines bear DNA with Bessie the meteor to make a tech-nullifying bear.
  • It Can Think: Thanks to Liv, Bessie is now sentient and extremely dangerous.
  • Made of Iron: Justified. Using bear DNA, Liv planned to create a monster strong enough to steal the gold she needs and defeat Big Hero 6.
  • Rock Monster: By using bear DNA, Liv Amara turns Bessie into a glowing rock-bear.
  • Supernatural Gold Eyes: Bessie is a lab experiment by Liv Amara, and has bright yellow eyes.
  • Sickly Green Glow: Both as a meteor and a bear mutant, Bessie shines a bright green light.
  • Walking Techbane: Her magnetic field causes all electronic devices (including Baymax) to go awry or just stop working. In "Lie Detector", after being turned into a monster by Liv, Bessie causes the team's tech to malfunction in the worst possible time when they're too near her.

Boss Awesome's Rogues Gallery

    Baron Von Steamer 

Baron Von Steamer

Voiced by: Jeff Bennett
Appearances: The Series (debut: "Fred's Bro-Tillion")

The arch-enemy of Boss Awesome that uses steampunk technology.

  • Arch-Enemy: Of Boss Awesome. Or at least, he tries to be, even after the latter retires. Fights with Supersonic Sue over that spot.
  • Artificial Limbs: His right arm is revealed to be a prosthetic.
  • Beard of Evil: Has a white goatee, completed with a large mustache.
  • Big "NO!": Played for laughs when Boss Awesome reveals who his true arch-nemesis is. It's cabbage soup.
  • Blind Mistake: Although not blind, his vision has gotten so poor due to age, he mistakens Wasabi for Fred.
  • Born in the Wrong Century: Given his usage of Steampunk gadgetry, he may be from the late 19th or early 20th century.
  • Crazy-Prepared: He booby-trapped one of his unused bases in case someone tried to investigate it.
  • Drill Tank: His main mean of transportation. Perfect for dramatical entrances.
  • Evil Brit: Has a Victorian-English accent.
  • Evil Gloating: His Fatal Flaw. Despite capturing Boss Awesome in every encounter with him, his tendency to gloat about his evil plan ends up being his undoing.
  • Evil Is Hammy: Is a classical overly-dramatic villain that gloats his evil plans and swears revenge when he gets defeated. And lets out an Evil Laugh in each of his appearances.

Appearances: The Series (debut: "Food Fight")

A professional chef and thief for hire who uses cooking blades as weapons.

  • Absurdly Sharp Blade: They're made of graphene, both lighter and stronger than steel, translucent and glowing blue, so sharp they're invisible from some angles and are even sharper than Wasabi's plasma blades. Scenes of her crimes often have multiple objects fall into slices when touched.
  • Animal Eyes: Gains a yellow pair of Hellish Pupils after being mutated by Liv Amara.
  • Anime Hair: When dressed in her supervillain ninja suit, her hair is spiked up.
  • Ax-Crazy: The fact she tries to slice her opponents on more than one occasion with her sharp graphene knives showcases she might not be all sane up there... It's not for nothing Boss Awesome's file on Momakase states her as "extremely dangerous". Gets worst after being mutated in Season 2.
  • Badasses Wear Bandanas: Wears a blue bandana and is probably one of the most badass villains introduced.
  • Berserk Button: Eating her food the wrong way is a big no no for her. Krei learned it the hard way.

  • Dark Is Evil: Wears black and dark shades of blue, and is a dangerous criminal.
  • Domino Mask: Wears a blue one as part of her Ninja attire.
  • Even Evil Has Standards: Sort of. Once she throws a piece of poisonous fish into Yama's mouth to get away with the anti-gravity device, she gives his thugs a vial of antidote for seemingly no reason when she could just let him die. Though not wanting to face a manslaughter charge might have something to do with it.
  • Evil Brit: Voiced by the British-Japanese actress Naoko Mori.
  • Evil Chef: She's a sushi chef and uses it to commit crimes.
  • Greed: Yama hired her to steal an anti-gravity machine from Krei, but Krei split the machine in half and hid it in two safes. She suggests that Yama hire her to steal the other half. Once she does, she backs out of the deal and decides to sell it on the black market instead and throws a piece of poisonous fish into Yama's mouth preventing him from stopping her ]double cross.
  • Evil Counterpart: To Wasabi, who both use sharp scientifically-improved blades to fight. The two are often designated to fight eachother.

  • I Have Your Wife: In "Fan-Friction", Momakase kidnaps Karmi because her fanfiction showed her as Hiro's (AKA "Captain Cutie's") girlfriend. Clearly, Momakase doesn't understand what fanfiction is, and Hiro did not react kindly to her calling Karmi his girlfriend.
  • Improbable Aiming Skills: No matter how far Momakase is from her target, she always hits it with her knives.
  • Inescapable Net: Traps Aunt Cass into one in order to both stop Big Hero 6 and refrain her to win their cooking dual. Ironically, she gets caught in the same net and is stopped this way.

  • Only Sane Woman: Of Obake's team. She's the most dangerous member of the group, and is annoyed by her teammates Globby and Noodle Burger Boy.
  • Punny Name: Her name is a pun on "omakase", a Japanese phrase that means, "I'll leave it to you." It can also refer to multi-course sushi dinners created at the chef's discretion rather than the customer's, tying back into Momakase's cooking motif.

  • Psychotic Smirk: It is rare to see her not do one.
  • Running Gag: Objects falling into slices shows Momakase has been around.

  • Smoke Out: Uses smoke bombs to escape with Krei's anti-gravity device in "Food Fight".
  • Smug Snake: Is fully aware of her skills as both a chef and a thief, and often mocks her foes in both areas, like saying that Baymax, Hiro, and Wasabi lasted three seconds longer against her than she expected.
    • Fatal Flaw: Her pride in her skills and arrogance are also these, combined with envy. In her skybox above the cooking duels, she sees Aunt Cass is the undefeated champion. Instead of leaving to put the anti-gravity device on the black market, she vows "Not for long." Becoming Cass' next challenger in a sushi duel gives Big Hero 6 the time to catch up to Momakase, and leads to her both beaten and captured and her follow-up Villainous Breakdown (see below).
  • Supernatural Gold Eyes: Gains these after her mutation at the hands of Liv Amara.
  • Supreme Chef: A villainous example.

A former real estate developer that gave up on his former life and all forms of technologies to go live in the woods.

  • Affably Evil: Before trying to kill Baymax, Ned is shown to be a surprisingly decent and even friendly guy. The problem is his Berserk Button concerning technology is almost unavoidable to push in such a futuristic age. However, it should be noted that this is Downplayed, as he really wasn't evil in the first place.
  • Anti-Villain: He's not really that evil, and generally leaves people alone if they leave him alone. He doesn't even keep fighting Big Hero 6 after regaining his humanity in his Season 2 appearance, and freely hitches a ride with Krei to get back to the forest.
  • Badass Beard: Has a long, scruffy beard and quickly showcases that living alone in the woods shaped him into a capable fighter.

  • Bigfoot, Sasquatch and Yeti: Sightings of the "hibagon", a Bigfoot-like monster, were actually him running around in the forest, with his long hair and beard assumed to be the monster's fur. He temporarily gets turned into an actual hibagon in the Season 2 episode "Muira-Horror".

  • Glowing Eyes of Doom: His hibagon form has yellow glowing eyes.

  • Meaningful Name: Named after the iconic leader of the "luddites", who despise all forms of technology.

  • Stupid Sexy Flanders: Constantly points out Chris' good looks as he fights him in "Muira-Horror!".
    Ned: [disoriented after his fight with Chris] Out of nowhere, from above... handsome sky man, beautiful eyes.
  • Supernatural Gold Eyes: As the Hibagon, Ned has bright yellow-gold eyes. And it's not just the scelera, it's the whole eye.
  • Sweet Tooth: He has a fondness for sweets that overtakes his fear of technology, accepting one of Baymax' lollipops without hesitation.
  • Technophobia: He's now evolved to this point, having a fear of any machinery whatsoever.
  • Ungrateful Bastard: Baymax saving him and bandaging his arm means nothing to him. He still believes Baymax will one day betray humanity along with all the other machines.

  • Verbal Tic: He has a tendency to call people who bother him "dumb-dumb".
  • Wild Hair: Justified, since he's been living in the wild for years, thus has no brush or scissors under the hand.
