    Tadashi Hamada 

Tadashi Hamada
"I'm not giving up on you!"
Voiced by: Daniel Henney
Appearances: Big Hero 6 | The Seriesnote 

Hiro's older brother and Baymax's creator.

  • Adorkable: Best proven when Baymax's video shows how happy he is after finally activating Baymax (after 84 tries), prompting him to run around and kiss Baymax.
  • All-Loving Hero: Tadashi's concerns extend to the general public; he developed Baymax with the sincere hope that the healthcare companion would help people all over the world. He is dedicated to helping others no matter what the cost is to him, a statement undeniably proven when he makes the ultimate sacrifice in an attempt to protect his teacher.
  • Always Second Best: Tadashi's voice actor Daniel Henney states that Tadashi "had his bad days" where he was jealous of Hiro's intellect and felt inferior to him, but pushed it away because supporting Hiro was more important.
  • Always Someone Better: It is implied that Hiro feels that he'll never be as great as Tadashi.
  • Anger Born of Worry: In the movie, after asking Hiro if he's okay and hurt as they escape Yama and his goons, Tadashi does a hilarious 180° and starts berating Hiro while driving on his moped.
    Tadashi: You okay?!
    Hiro: Yeah!
    Tadashi: Are you hurt?!
    Hiro: No!
    Tadashi: Then what were you thinking?! Knucklehead!
  • Arc Words: "Someone has to help!" becomes this to Hiro. Justified as they're Tadashi's last words and they had a great impact on Hiro.
  • Asian and Nerdy: Like Hiro, Tadashi is half White and half Japanese, and is a robotics student.
  • Augmented Reality: In "Obake Yashiki", Obake uses projections via contact lenses on Hiro to give him the impression Tadashi came back from the dead.
  • Badass Biker: Escapes Yama and his goons on his moped like a pro. Too bad he and Hiro get arrested soon after, though.
  • Back from the Dead: In the series episode "Obake Yashiki", or perhaps his spirit but this, unfortunately, is not the real Tadashi.
  • Big Brother Bully: Played for Laughs and subverted. He grabs Hiro by the ankles and shakes him around to get him to come up with a project for the tech showcase.
  • Big Brother Instinct: Rushes in to save Hiro when he is about to be beaten up by Yama's goon's after Yama discovers that Hiro hustled him.
  • Big Brother Mentor: For Hiro. As the only male figure in his little brother's life, he has carried the burden of responsibility from a young age, knowing he had to lead Hiro and be a good role model.
  • Big Damn Heroes: Arrives on his scooter with perfect timing to save Hiro from an angry Mr. Yama.
  • Big Man on Campus: According to Wasabi, Tadashi is considered "a legend" at SFIT.
  • Big Ol' Eyebrows: Like Hiro, Tadashi has bushy eyebrows.
  • Brainy Brunette: Tadadshi has black hair, a student of SFIT, and Baymax's creator.
  • But Not Too Foreign: Like Hiro, Tadashi is half Japanese, half white.
  • The Cameo: Tadashi has multiple ones through the series, mostly through photographs and video footage from Baymax's tests. Though he's not always in the center of the intrigue, it showcases that he's not forgotten and will always be part of Hiro's life.
  • Canon Foreigner: In the original Big Hero 6 comics, Hiro never had a sibling. Tadashi is, essentially, a stand-in for comic-book Hiro's father.
  • Catchphrase:
    • Says "unbelievable" whenever exasperated.
    • "Look for a new angle."
    • "I'm not giving up on you."
  • Chronic Hero Syndrome: He feels the need to help, even when there's nothing that can be done. This gets him killed, trying to save Professor Callaghan from a burning building despite his own lack of rescue experience or equipment.
  • Cool Big Bro: Tadashi is eternally supportive of Hiro, and encouraged him to do something great with his genius.
  • Dare to Be Badass: He encourages Hiro to use his smarts for something greater.
  • Dead Hat Shot: After being killed off-screen, there's a shot of Tadashi's cap while Hiro is heard screaming his brother's name in the background.
  • Deadpan Snarker: "Wow. Washed up at fourteen. So sad."
  • Death by Origin Story: Deconstructed. His death is what spurs Hiro to fight Yokai, but his grief from it is what drives him into Revenge Before Reason, nearly murdering Yokai when he finds out who he is.
  • Death Glare: Tadashi gives a hilarious one to Hiro when they're both in jail; most specifically, as Hiro has his cell to himself due to being a minor and Tadashi is squished against the bars of the cell by the other botfighters.
  • Decomposite Character: He has some traits that originally belonged to Hiro's older and more mature comic counterpart, such as being the one to build Baymax.
  • Determinator: Tadashi did eighty-four tests before Baymax finally worked. He also wasn't going to give up on Hiro constantly encouraging him to do something with his life.
    Tadashi: I'm not giving up on you...
  • Dies Differently in Adaptation: In the manga adaptation, Tadashi doesn't die in a fire, he gets sucked into a portal while trying to help Robert Callaghan bring Abigail back. Hiro believes that he could be alive in Another Dimension but Baymax confirmed that he wasn't in the Acid-Trip Dimension where they found Abigail.
  • Dub Name Change: In the Korean and Mandarin Chinese dub of the film, Tadashi is renamed "Teddy Armada".
  • The Dutiful Son: More like "The Dutiful Nephew", but Tadashi is the more responsible one than Hiro, and makes it clear that his brother has to make it up to their aunt for his illegal botfighting.
  • Establishing Character Moment: His first scene involves him saving Hiro from Yama and his goons, asking if he's alright before punching him for doing such a dangerous stunt, and also asking Hiro if he plans to use talents for something better.
  • Exhausted Eye Bags: Can be seen in one of video footages of him testing Baymax.
  • Famous Last Words: "Someone has to help!"
  • Fanboy: Hiro mentions that Tadashi was a big fan of Trevor Trengrove and got inspired by his theory to build Baymax. Turns out the theory was actually Wendy Wower's, which Trengrove stole from her.
  • Fatal Flaw: His selflessness when he tries to save Callaghan from the fire. He doesn't consider that Hiro might try to follow him inside (which Hiro does) or the grief it would cause Hiro if he fails.
  • Foolish Sibling, Responsible Sibling: Tadashi is the Responsible to Hiro's Foolish. He regularly attends school (unlike Hiro, who spends most of his time bot-fighting since he graduated from high school early) and encourages Hiro to be more productive with his intelligence. In the beginning of the film, he's the one who bails Hiro out of trouble when Yama's goons are about to beat him up.
  • The Gadfly: Is not above playfully teasing his brother, as revealed in the scene where he tells him his fly was down for the whole time Hiro presented his project at the showcase... and it was correct.
  • The Ghost: Both literally and figuratively. It was stated by the creators during their panel at the 2018 San Diego Comic Con that he would always have a presence in the show.
  • Handshake Substitute: He and Hiro would fist bump and then make explosion noises.
  • The Heart: Tadashi provides the optimistic drive to the motivations of his friends and his younger brother.
  • Hidden Depths: Despite being the Determinator and always encouraging Hiro to never give up, "Failure Mode" shows a complete different side of Tadashi: being frustrated after 57 missed attempts and considering giving up. Shows that even if he was optimistic and determinate, Tadashi was still human and had bad days where he considered giving up was an option, thinking spending so much time and energy on Baymax was pointless and would never work.
    Hiro: I never saw him like that...
  • Hollywood Nerd: He looks like a male model, or perhaps a Disney Prince, but he's skilled with building robots.
  • Honor Before Reason: He goes in to attempt to save Callaghan from a building completely engulfed in flames, with nothing but one eyewitness account that Callaghan was still in the building in the first place. While this is very noble, on the other side of the coin, he doesn't even remotely consider that his brother may go in after him, which Hiro does in fact attempt to do or the grief he will inflict upon Hiro if he fails in his rescue attempt (which he does).
  • Iconic Item: Is rarely seen without his San Fransokyo Ninjas baseball cap. It's one of the few things Hiro has of him after his death.
  • It Runs in the Family: He scolds Hiro for bot fighting the exact same way Aunt Cass scolds him and Hiro after bailing them out of jail. Also the use of the word "knucklehead".
  • Killed Offscreen: Died in the Exposition Hall explosion trying to rescue Callaghan. The only thing the audience sees is the building exploding, and a shot of Tadashi's cap while Hiro screams his name in the background.
  • Living Emotional Crutch: To Hiro, Tadashi isn't just his big brother. He's also his best friend and the most important figure in his life. His death sent Hiro into depression.
  • Meaningful Name: A common meaning for Tadashi's name is "loyal" and his name sounds like the Japanese adjective tadashii (正しい) which means "fair," "proper," or "righteous." All of which matches his Nice Guy and All-Loving Hero personality.
  • Mixed Ancestry: He's half white and half Japanese.
  • Mr. Fanservice: Is definitely attractive, and his clothes have been shown emphasizing his muscles and broad shoulders. Even the series' exaggerated geometric style seem to show those well.
  • Nephewism: He and Hiro were raised by their Aunt Cass after their parents died.
  • Nerds Are Sexy: He's a robotic major and extremely attractive.
  • Nice Guy: His character description here indicates him to be one:
    Tadashi is a good guy. He just is. He actually developed, built and programmed a state-of-the-art nursebot—a Healthcare Companion named Baymax that will likely help millions worldwide. But it's his role as big brother that makes Tadashi truly special. Every kid needs a guy like Tadashi looking out for him, and Hiro knows just how lucky he is to have him in his life.
  • Nice Hat: Has shown to frequently wear a cap with the team logo of the San Fransokyo Ninjas on the front. The back of his cap (and a white T-shirt he frequently wears) has the Ninjas' team symbol.
  • Only Friend: To his younger brother, Hiro, before he introduces Hiro to the rest of the team.
  • Out-of-Character Alert: In "Obake Yashiki", "Tadashi" telling Hiro he doesn't need limits and that he shouldn't waste his time fixing Baymax confirms for Hiro that it's not really his brother.
  • The Paragon: Tadashi will always be there to save his brother, but at the same time wants to point Hiro in the right direction.
  • Parental Substitute: Tadashi acts not only as a Cool Big Bro to Hiro, but also acts as a father figure.
  • The Pollyanna: Despite losing his parents at a young age and taking a huge responsibility by being Hiro's father figure, Tadashi is an optimistic individual that doesn't see giving up as an emotion, and shares this point of view to his younger brother.
  • Posthumous Character: Since he died in the movie, Tadashi is this in the series where he still has cameos in video footages, pictures, and there's the infamous "Obake Yashiki" episode where Obake uses a ultra-realistic hologram of Tadashi to trick Hiro.
  • Pretty Boy: He's quite the handsome young man.
  • Puppy-Dog Eyes: This scene.
    Baymax: On a scale from one to ten, how would you rate your pain?
    Hiro: Physical? Or Emotional? (glares at Tadashi)
    (Cue puppy dog eyes and frown from Tadashi.)
  • Raven Hair, Ivory Skin: Like Hiro and GoGo, he has black hair and pale skin.
  • Red Oni, Blue Oni: The mature, responsible Blue Oni to Hiro's brazen, impulsive Red Oni.
  • Smart People Build Robots: He created Baymax.
  • Something They Would Never Say: In "Obake Yashiki", Hiro starts to realize the Tadashi he's been talking to is a not really his brother when he tells him limits will slow him down and to not focus his energy on continuing his old work.
    Hiro: [backing away from the fake Tadashi] Tadashi would never say those things [...] You are not my brother!
  • So Proud of You: In his own way to Hiro after he got an acceptance letter to San Fransokyo Institute of Technology.
    Tadashi: [to Hiro] Welcome to nerd school, nerd.
  • Straight Man and Wise Guy: The Straight Man who goes to college and encourages his little brother to do the same, to Hiro's Wise Guy who spends his free time competing in illegal bot-fights.
  • Tall, Dark, and Handsome: Tadashi is quite tall, black-haired, and extremely good-looking.
  • Tall, Dark, and Snarky: He also has a sarcastic side.
  • Vague Age: It doesn't help that the Japanese media calls him 21, while Hiro's San Fransokyo Files say he's 18. The general consensus is that he's somewhere between the two.

    Aunt Cass 

"For 10 years I have done the best I could to raise you. Have I been perfect? No! Do I know anything about children? No! Should I have picked up a book on parenting? Probably?! Where I was going with this? I had a point..."
Voiced by: Maya Rudolph
Appearances: Big Hero 6 | The Series

Hiro and Tadashi's aunt, who adopted them after their parents died.

  • The Ace: When it comes to cooking competitions, Cass is the unbeatable champion who wins all battles without struggle AND without cheating. She even defeats the supervillain and Evil Chef Momakase.
  • Action Mom: More like "Action Aunt". "Food Fight" shows that Aunt Cass is quite acrobatic. Oh, and she's not afraid to use knives to defend her nephew from harm.
  • Adorkable : She has an almost child-like glee whenever she gets excited. It's just so cute.
  • Adult Fear: Her sisternote  and brother-in-law die, leaving behind her young nephews who she raises as her own. Then her oldest nephew dies in a fire trying to save his teacher.
  • Amazingly Embarrassing Parents: Her shipper tendencies around Hiro and Megan embarrasses her nephew.
  • Anger Born of Worry:
    • In the movie, she's introduced being mad against her nephews after being arrested, and worrying about their well-being as well as how she's been raising them over the past 10 years.
    • In "The Bot-Fighter", after Hiro gets arrested, she has to bail him out yet again. She's understandably mad, and grounds Hiro. After Hiro notes he's never seen Aunt Cass that mad in a long time, Baymax notes it's out of concern for him.
  • Badass Driver: Aunt Cass drives away from the buddy guards like a pro.
  • Badasses Wear Bandanas: Wears a yellow bandana in the Food Fight cooking competitions. She quickly showcases to be a badass chef who contrary to her opponents, wins all the duels without cheating once.
  • Battle Trophy: As of "Food Fight", Aunt Cass collects all the knives of the chefs she defeated in the Food Fight competitions.
  • Canon Foreigner: She was made specifically for the film adaptation. Possibly as a stand-in for Hiro's mother, who is not dead in the comics.
  • Cheaters Never Prosper: She teaches this to those who try to cheat to win against her in "Food Fight." She ends up taking their knives as a Battle Trophy.
  • Chef of Iron: Becomes a food-fighter in "Food Fight".
  • Collector of the Strange: Has an entire room full of knives that she gained from the chefs she defeated in "Food Fight".
  • Comfort Food: After bailing Hiro and Tadashi out of jail, she starts eating a doughnut, while lampshading it. She also encourages it in Hiro, trying to comfort or reward him with his favorite foods, like hot wings.
  • Cool Aunt: Took in her nephews when they were orphaned and is an eternally loving, supporting figure for both.
  • Cuddle Bug: Is always prone to hugging her nephews. After Tadashi's death, she has a "last hug" tendency, which is giving a second last hug to Hiro before he goes somewhere.
  • Damsel out of Distress: Though the anti-gravity device helped, Cass escaped the net Momakase trapped her in and is the one who neutralized Momakase with the same net by herself.
  • A Day in the Limelight: "Food Fight" turns around Aunt Cass participating in the underground cooking competitions, which are also attented by the villain Momakase.
  • Dub Name Change: In the two french versions, Aunt Cass' name is changed to "Tante Cassie" (Aunt Cassie) since "Cass" sounds too anglophone.
  • Dude Magnet: Over the course of the series, she catches the eye of Krei, Mel and Chief Cruz.
  • Establishing Character Moment: Cass' first scene has her hugging her nephews in relief after posting their bail and then angrily pulls their ears for scaring her.
  • Fangirl: Fangirls hard when renowned chef Bolton Gramercy is in her café. Turns out to be a light case of Broken Pedestal when she realizes how big of a Jerkass he is.
  • Genki Girl: A rare adult type, but she is always excited and happy.
  • Good Parents: She's an adoptive parent who's always doing her best to raise Hiro and Tadashi.
  • Hartman Hips: Let's just say that if she were to decide to have children of her own, she would be well equipped for it. Seriously, though, her hips are wider than her shoulders.
  • Kindhearted Cat Lover: Owns a cat named Mochi and her coffee shop is named the "Lucky Cat Café."
  • Mama Bear:
    • In the movie, she goes to the police station to bail out Hiro and Tadashi after they get into an illegal bot fight and lectures them for getting themselves in trouble afterwards, being genuinely concerned for their safety, and doing whatever she can to be the best possible motherly figure.
    • In "Food Fight", when Aunt Cass was gonna get Hiro whom she thought was out botfighting, she was ready to use knives in order to protect him and herself from harm. Do not mess with Hiro...
  • Nervous Wreck: Loses all control when worried about her nephews, and she copes with it with food.
  • Nice Girl: Nurturing, loving, caring, amiable, devoted, supportive, and motherly.
  • Oblivious to Love: She doesn't seem to be aware Chief Cruz has a thing for her.
  • Only Known by Their Nickname: Everyone calls her "Cass", which is a nickname derived from "Cassandra" or "Cassidy".
  • Only One Name: Only known as "Aunt Cass", and no clue of her last name.
  • Outliving One's Offspring: Her eldest adoptive son/nephew, Tadashi, dies in a fire at only 18 or 21.
  • Parental Obliviousness: Aunt Cass has no idea of her nephew's superhero whereabouts and she buys most of Hiro's lies, despite the fact he's a terrible liar.
  • Parental Substitute: Becomes one to Hiro and Tadashi after their parents died, then even more so to Hiro after Tadashi dies.
  • Parents as People: Lampshaded. Cass never expected to be a parent, nor did she know anything about being a parent. But she loves both her nephews, and they clearly love her back.
  • The Pollyanna: After Tadashi's death, she maintains her cheerful and optimistic personality for Hiro's sake, even if it's clearly a façade and she obviously misses her nephew.
  • Promotion to Parent: She mentions that she never expected to be a parent, but she has raised Tadashi and Hiro for ten years and always refers to them as her "boys."
  • Shipper on Deck: Introduces Hiro to Megan, the daughter of an old friend of hers, and is trying really hard to make them an item.
  • So Proud of You: Cass always tells Tadashi and Hiro how proud she is of their accomplishments.
  • Stepford Smiler: In the movie, she forces herself to smile in Hiro's presence in order to cheer him up after Tadashi's death, even if it's quite obvious she's suffering herself.
  • Supreme Chef:
    • "Fred's Bro-tillion" had Cass cater for Fred and his family (as Hiro recommended her for the gig); she later gets a stack of orders to cater OTHER events as well.
    • Demonstrated in "Food Fight," where in underground cooking duels she wins strings of matches after defeating her mentor. Given "cheating is encouraged" in said duels her ability to show Cheaters Never Prosper makes her a Chef of Iron. In the duels she wins the knife set of her opponent as a Battle Trophy, and when her mentor asks for his "Nana's knives" back, she showed him her Trophy Room before asking which knives "were his Nana's."
    • Subverted in "Lie Detector", though it's Played for Laughs. Even if Cass is an excellent chef, she improvises a recipe of " acai-salami bowl". It's as disgusting as you might imagine, and Hiro lies about it being good not to hurt Aunt Cass' feelings.
    Aunt Cass: [grimaces after tasting her acai-salami bowl] Ugh! Can't believe Hiro likes this!
  • Sweet Tooth: For pastries, as she has her own café.
  • Trophy Room: In "Food Fight", Cass beat so many chefs in the underground cooking competitions that she has a room dedicated to the knives she gained from them. Bolton, who asked for his Nana's knives back, is shocked, not to say the least.
    Aunt Cass: Which one are your Nana's?
  • Worthy Opponent: To Momakase. Though it's inverted as Momakase is determinate to annihilate Cass since she thinks she's better than her.


Appearances: Big Hero 6 | The Series

The Hamada family's pet calico cat.

  • Action Pet: Mochi looks like your average, sweet, fat cat. But mess with his owner Hiro or Baymax, and you'll regret it. See for yourself as he fights Hibagon Ned and wins!
  • Animal Gender-Bender: He's a male calico cat.note 
  • Badass Adorable: Took on Hibagon Ned by himself in "Muira-Horror!" to save Hiro, GoGo, Krei and Baymax.
  • Beware the Nice Ones: Mochi is the sweetest cat... until you try to attack Hiro and Baymax.
  • Butt-Monkey: This poor cat always finds himself in the craziest situations.
  • Cats Are Mean: Completely averted, as Mochi, a chubby Japanese bobtail cat that likes to snuggle, is one of the nicest Disney cats to date.
  • Cats Are Snarkers: Look at Silent Snarker below.
  • Cats Hate Water: In his short with Baymax, Mochi yowls and flails whenever the robot tries to clean him in the sink.
  • Cat Up a Tree: The premise of the "Save Mochi" Big Chibi 6 short.
  • Cool Cat: Already a nice, cuddly cat, he becomes even cooler after becoming "Slow Clap Cat". And then he beats up Hibagon Ned by himself in "Muira-Horror!".
  • Cute Kitten: He may not be a kitten, but no one can resist Mochi's cuteness.
  • Distressed Dude: Gets kidnapped by Mr. Sparkles and threatened to be blasted to space after his "Slow Clap Cat" video got more popular than his show.
  • Death Glare: Gives one to Hiro after he threw him up the stairs.
  • Evil-Detecting Cat: More of a "Jerkass-Detecting Cat"; when Krei goes to take Aunt Cass out on a date, he hisses at him.
  • Fat Cat: He's so fat that he looks like a ball.
  • Fluffy Dry Cat: In "Food Fight", Baymax pets Mochi at one point and the static causes his hair to brissle.
  • Freeze-Frame Bonus: Mochi can briefly be seeing playing with a laser-pointer during Hiro's Hard-Work Montage.
  • Green-Eyed Monster: Played for Laughs when Cass adopts a Mayoi and gives it more attention than to Mochi.
  • The Internet Is for Cats: Becomes a meme after Honey Lemon's video of him "slow clapping" becomes viral.
  • Meaningful Name: He is named after a Japanese rice cake, kinda fitting as he looks like he's had too much cake.
  • Nice Guy: A sweet, docile and affectionate cat that loves being anywhere he can get attention.
  • Papa Wolf: Protects both his owner Hiro and Baymax from Ned Ludd in Hibagon form by jumping on his face and clawing him.
  • Silent Snarker: Just look at his face as he watches Hiro and Aunt Cass switching roles after Aunt Cass sneaks out in "Food Fight".
  • Team Pet: The series seems to be treating him as this to the heroes, seeing as he got a short all to himself. And then there's him beating Hibagon Ned by himself.
  • That Poor Cat: He gets tossed up the stairs by Hiro when he's trying to hide Baymax from Aunt Cass. He turns out to be okay but is not happy with Hiro and runs away howling when he approaches.
  • Tropey, Come Home: Mochi has the tendency to wander off from home more than once in the series and it's up to the team to bring him back.

The Frederickson family


"Welcome home, Master Frederick."
Voiced by: David Shaughnessy
Appearances: Big Hero 6 | The Series

A stoic butler who works for Fred's family.

  • Badass Driver: "The Fate of the Roommates" has him getting mixed up in a street race, leading to some very quick maneuvering a limousine of all things, including barely avoiding hitting a woman with a baby carriage and a truck in quick succession. Throughout the whole thing, he still keeps his stoic expression. Later in the episode he infiltrates one of said street races and manages to recover from being put in a spin, outmaneuvers the person who put him in that spin and causes him to drive off a bridge, and almost catches Mr. Sparkles when he hijacks the other remaining car, being stopped only by the fact that the latter had an egg- and bomb-dropping flying chicken robot at his disposal.
  • Badass in a Nice Suit: Badass Driver in a butler tux.
  • Badass Mustache: A Badass Driver who wields a small, pointed mustache (the same as Alfred, nonetheless).
  • Battle Butler: Downplayed. So far, Heathcliff didn't show any combat abilities... but he's one hell of a badass driver.
  • The Comically Serious: Despite always acting like a reserved, professional butler, he ends up participating in some odd and mundane situations, such as giving Fred (and Baymax) a fist bump, serving as the team's Training Dummy, and eating a pastry while having the tech tested on him.
  • A Day in the Limelight: Has a very prominent role in "The Fate of the Roommates", where he's the key to discover who is behind the illegal street racing.
  • High-Class Glass: Wears one as part of his costume when he infiltrates Mr. Sparkles and Yama's race.
  • Ironic Echo: When Heathcliff goes undercover in Mr. Sparkles' underground racing league in "The Fate of The Roommates", an arrogant opponent underestimates him and mocks his butler appearance before asking Heathclif to "fetch him an iced tea". When the same opponent tries to get rid of Heathcliff, only to be eliminated instead, Heathcliff asks him to "fetch him an ice tea".
  • The Jeeves: A classic example of the stone-faced, well-mannered, devoted butler.
  • Master Actor: Boss Awesome notes Heathcliff is an amazing actor which permitted him to go undercover for him and the bad guys always bought it.
  • Master of Disguise: Boss Awesome reveals that he used Heathcliff in undercover works back in his superhero days, and Heathcliff could always pull it off without having his cover be blown.
  • Nice Guy: Even if he's stoic, he's a polite, well-mannered butler.
  • Not So Above It All: While poised and stoic, there are moments where Heathcliff is... not as poised and stoic. Moments like he's using the limousine's hot tub, being excited over snow cones or insulting an adversary racer.
  • Not So Stoic:
    • While normally reserved, he does crack tiny smiles at the team.
    • He's also a bit baffled (or amused) by Baymax's fist-bumping.
    • He is also easily ticklish.
    • He loves snow cones. A lot. "Fan-Friction" shows him getting a snow cone from Honey Lemon's iceberg.
    • Not even Heathcliff can hide his contempt for Binky.
  • Perpetual Frowner: Though his face is in constant deadpan mode, he does occasionally crack smiles.
  • Servile Snarker: Has his moments. Makes sense when you're working for a Cloud Cuckoo Lander like Fred.
    Heathcliff: [to an arrogant racer who previously mocked his butler appearance] Be a dear and fetch me an iced tea.
  • Shout-Out: To other valets like Jarvis and Alfred. Especially since Fred's dad is actually a superhero, so BH6's training is nothing unusual for him.
  • The Stoic: He shows no reaction to Fred bringing his friends home while drenched, or serving as a practice Yokai for the team.
  • Trademark Favorite Food: The series reveals he really loves snow cones.
  • Training Dummy: He helps the team practice by letting them attack him, although they hold back their attacks to ensure he doesn't get hurt.
  • Unfazed Everyman: He had no problem serving as the team's training dummy or even seeing them become superheroes, since he was Boss Awesome's right-hand man back in his superhero days.

    Mr. Frederickson 

Boss Awesome (Frederick Frederickson III)
Click here  to see him in his superhero suit

Voiced by: Stan Lee
Appearances: Big Hero 6 | The Series

"A real hero helps everyone in need, even their worst enemies."

A retired superhero and Fred's father, who bears an intentional likeness to a certain comic book creator.

  • Action Dad: To Fred, as showed in "Supersonic Sue".
  • All-Loving Hero: He vows to help everyone in need, even his enemies.
  • Ascended Extra: We see more of him in the series, including his superhero past.
  • "Awesome McCool" Name: His superhero alias is "Boss Awesome".
  • Badass in Distress: Discussed and exploited. Mr. Frederickson tells the team that back in his superhero days, he let Baron Von Steamer capture him so he could hear his evil plan and defeat him easily. And it worked each time.
  • Badass Mustache: Has a white mustache and was a badass superhero. When he comes back from retirement to help Big Hero 6 in "Supersonic Sue", Boss Awesome proves he always remained a badass.
  • Batman Gambit: He always let Steamer capture him because he knew he'd gloat his evil plan, thus he'd easily escape and stop him in time.
  • Big Damn Heroes: Comes just in time to help the team against his old foes in "Supersonic Sue".
  • Blue Is Heroic: His superhero suit is mostly blue, with red and yellow highlights.
  • Bookcase Passage: The way into the secret room with his gear is by pushing a painting of the family, causing the wall behind it to open.
  • Boots of Toughness: For extra awesomeness, Mr. Frederickson fights Supersonic Sue and Baron Von Steamer wearing cowboy boots.
  • Calling Your Attacks: Downplayed. Boss Awesome doesn't scream the name of his attacks as he does them, but he does have some signature moves.
    Boss Awesome: [fighting Baron Von Steamer] I call this one [move] "The Blender".
  • The Cape: He is the archetypal superhero in a classical suit (albeit lacking an actual cape), a wise and caring man who believes that a real hero helps everyone in need - even his enemies.
  • Catchphrase: "Classic!"
  • Cool Old Guy: Even though he's only Fred's father he looks about as old as Stan Lee, if a little more color in his hair, but he casually wrestles bulls. In "Supersonic Sue", he briefly comes out of retirement and defeats the duo of his old arch-enemies.
  • Cool Shades: Wears Stan Lee's iconic dark specs. His superhero suit also has opaque yellow ones.
  • Daddy Had a Good Reason for Abandoning You: Downplayed. Fred mentions that he rarely sees his father because he is away on their vacation island for long periods of time. Likely, he's off superheroing during these times, but that doesn't mean Fred doesn't miss him. Despite that, Mr. Frederickson clearly loves his son and Fred can always video-call him when he needs to.
  • Dark Is Good: His "Boss Awesome" suit is mostly black, and he's a superhero.
  • A Day in the Limelight: Even as the Ascended Extra in The Series, he is the Hero of Another Story most of the time. In "Supersonic Sue", however, we get to see him actually fighting as he saves Big Hero 6 from his old arch-enemies. The episode is dedicated to the memory of Stan Lee.
  • Genre Savvy: Justified. Being a superhero for decades, he knows villains' mindsets and all their tactics.
  • Good Parents: Despite travelling a lot, he clearly loves his son and is always there to give him advice about superhero business.
  • Happily Married: Seems to have a loving marriage with Mrs. Frederickson, as the two of them often leave in vacation together.
  • Heroes Want Redheads: Married Fred's mother, who is a redhead.
  • Hero of Another Story: He was a superhero back in the 70's and now travels the world wrestling yetis and bulls.
  • Ink-Suit Actor: He is clearly modeled after Stan Lee, his voice actor.
  • Lantern Jaw of Justice: He has a square chin, befitting a classic superhero.
  • Like Father, Like Son: Secretly a superhero. And they wear their underwear the same way.
  • May–December Romance: Implied. Fred's mother looks far younger than her husband. Either she's younger than him or simply looks younger than he does.
  • Mysterious Parent: Mentioned in passing during the events of the film and revealed in the post-credits scene.
  • Nice Guy: A sympathetic, wise man that gives good advice and cracks jokes.
  • The Obi-Wan: He becomes somewhat of a mentor to Big Hero 6, as they take up his role as protectors of San Fransokyo.
  • Old Superhero: Was a superhero back in the 70's, and comes out of retirement briefly in "Supersonic Sue" to rescue the team from his old arch-enemies.
  • Off Hand Back Hand: A staple of his fighting style, at least with the way he usually appears in The Series: the main characters call him, and as he gives them advice, he fights yetis and bulls hardly even looking at them.
  • Primary-Color Champion: His superhero suit is red, blue and yellow. Classic.
  • Reasonable Authority Figure: Though annoyed at his son not keeping the secret, he is still happy to let Fred and his friends use his hidden superhero lair for their crime fighting.
  • Red Is Heroic: Wears red in his superhero suit.
  • Retired Badass: Although long retired from superhero business, he hasn't lost his game when he saves Big Hero 6 from Baron Von Steamer and Supersonic Sue and is still as athletic as he was back in the day.
  • Underwear of Power: A part of his supersuit resembles blue underwear.
  • Unnamed Parent: Credited only as "Fred's Dad." In the TV series his superhero name is "Boss Awesome", and since his son is called "Frederick Frederickson the 4th", it implies that his name might be "Frederick Frederickson the 3rd".
  • Wall Jump: His move "The Blender" consists of taking a boost on the wall and jump forward at your opponent.
  • Would Hit a Girl: He showcases a wrestling move on Supersonic Sue during their fight. Though she is a supervillain trying to defeat him...

    Mrs. Frederickson 

Mrs. Frederickson, née Flammarion

Voiced by: Susan Sullivan
Appearances: Big Hero 6 (picture only) | The Series (debut: "Fred's Bro-Tillion")

Fred's mother and the wife of Mr. Frederickson/Boss Awesome.

  • Absurdly Youthful Mother: Either she really is younger than her husband, or she's Older Than She Looks.
  • Ambiguous Situation: It's unknown whether or not Mrs. Frederickson is aware of her husband's superhero past. Considering Fred himself didn't know until the post-credits scene of the movie, she most probably doesn't.
  • Auntie Pennybags: Is incredibly friendly to Fred's friends, actually listens to Hiro when he gives suggestions on on a caterer, and ultimately decides that pleasing her fellow aristocrats is overrated and happily enjoys a party at a humble cafe.
  • Catchphrase: In "Fred's Bro-Tillion":
    Mrs. Frederickson: "Binky, wait!"
  • Comically Missing the Point: Although she sees a huge hole in Fred's room and sees it in a mess, she's only concerned Fred is not dressed for their dinner with Orso Knox.
  • Early-Bird Cameo: Appeared in a family painting in the film.
  • The Everyman: Contrary to her husband and son who are superheroes, Mrs. Frederickson is a normal aristocratic woman.
  • The Fashionista: Flashbacks of Fred's childhood shows that Mrs. Frederickson has a diversified wardrobe for any occasions.
  • Fiery Redhead: Averted. While a perfectionist, she has a poised and collected temper, though she's more prone to worry fits rather than anger fits.
  • Giant Poofy Sleeves: She seems to loving wearing dresses who has these.
  • Good Parents: Despite wanting Fred to be into aristocracy like her, Mrs. Frederickson respects his interests of comic books and clearly loves her son.
  • Graceful Ladies Like Purple: She wears a purple dress during Fred's bro-tillion.
  • Hair Decorations: Fred's flashbacks shows that Binky often wears headbands or hats.
  • Happily Married: Seems to have a loving marriage with Mr. Frederickson, as the two of them often leave in vacation together.
  • Horrible Judge of Character: Puts trust into Liv Amara, wanting to fund her company and like everyone else, has no idea of her true motives. It puts her in danger, since those who fund her end up being mutated.
  • It Runs in the Family: "Joy screaming". Despite Fred saying his mother's is embarrassing, he actually does the exact same thing when he's excited.
  • Light Is Good: She mostly wears white and is Fred's kind mother.
  • Likes Older Men: Implied. She's definitely younger than Mr. Frederickson.
  • May–December Romance: Implied. Fred's mother looks far younger than her husband. Either she's younger than him or simply looks younger than he does.
  • My Beloved Smother: Downplayed. While not smothering towards Fred, she desperately wants him to make a good impression (especially in Binky's presence).
  • Nice Girl: While a tad neurotic and perfectionist, she truly is a kind-hearted woman.
  • Nervous Wreck: She tends to worry easily, especially for her son and their image as a family.
  • No Name Given: Only known as "Mrs. Frederickson".
  • The Perfectionist: Her debut episode in "Fred's Bro-Tillion" showcases this. During Fred's Bro-Tillion, she wants everything to be "absolutely perfect", from the catering, to her son's appearance and mannerisms, in order to impress Binky.
  • Proper Lady: She's an aristocrat who loves luxury and fanciness.
  • Rich Bitch: Completely averted. While rich, she's a good mother to Fred and an overall kind and friendly woman, in contrast to Binky.
  • Skewed Priorities: In "Big Problem", Fred's mom enters Fred's room after Orso Knox attacked to find it completely trashed with a giant hole in the wall...and is only concerned that Fred's not dressed for dinner.
  • So Proud of You: In the end of "Fred's Bro-Tillion", Mrs. Frederickson decides to no longer lose her time trying to impress Binky and tells Fred how proud she is of him.
  • Vague Age: She looks far younger than Mr. Frederickson, though she can also simply look younger.




Voiced by: John Michael Higgins
Appearances: The Series (debut: "Mini-Max")

"Mini-Maximum Justice!"

Fred's sidekick robot.

  • Adaptational Badass: The Mini-Max from the Big Hero 6 manga that was simply a robotic companion to Aunt Cass that was not programmed to fight whatsoever. Here in the series, he's Fred's robot sidekick and can hold a fight.
  • Adaptation Relationship Overhaul: In the manga, Baymax was Aunt Cass' robot. While in the series, he's Fred's robot and the occasional Seventh Ranger to the Big Hero 6 team.
  • Alcohol-Induced Idiocy: Just like Baymax, when Mini-Max is on low-battery, he acts like he had too much to drink.
  • Badass Adorable: As seen in his debut episode "Mini-Max" when he takes on foes with ease.
  • Bad "Bad Acting": Justified, since Mini-Max is a robot and is only programmed to be Fred's over-the-top sidekick. It doesn't make his terrible impression of Mochi less hilarious:
    Mini-Max: MINI-MAXIMUM CAT IMPRESSION! Purr, purr! In the name of all that is cute! Purr!
    Fred: [Aunt Cass] might not buy it.
  • Big Guy, Little Guy: The Little Guy to both Fred and Baymax's Big Guys.
  • Blue Is Heroic: A heroic robot with a dark blue armor and red highlights to boot. His eyes are blue, too.
  • Brainwashed and Crazy: When in contact with too much water, Mini-Max's personality switches from good to bad, and when he's bad, he's bad.
  • Brutal Honesty: Can be quite blunt by moments. Justified, since he's a robot.
    Mini-Max: [reacting to Fred and Globby's terrible Cockney accents] Both your accents were highly inaccurate!
  • Butt-Monkey: Despite being a fighter, his small size causes villains to toss him aside as if he was nothing on more than one occasion.
  • Canon Immigrant: Was a minor character that first appeared in the manga adaptation, that made it into Disney's canon as of the series.
  • Captain Obvious: A trait he shares in common with Baymax.
    Mini-Max: [pours water on Fred's cellphone to cool it down, only to have it explode] I should not have used water!
  • Catchphrase: "Mini-Maximum [insert line here]!!"
  • Cute Machines: Admit it, he's adorable, but in costume and out.
  • A Day in the Limelight: The plot of "Mini-Maximum Trouble" is about Mini-Max's accidental Face–Heel Turn.
  • Drunk on Milk: As seen in "Muira-Horror!", Mini-Max has the same drunk behavior as Baymax when on low-battery.
  • Evil Is Hammy: He maintains his hammy personality when he becomes evil in "Mini-Maximum Trouble", complete with an Evil Laugh. Fortunately, it doesn't last.
  • Evil Makeover: In "Mini-Maximum Trouble", when temporarily a bad guy, Mini-Max trades his blue armor for a black one, completed with red highlights.
  • Face–Heel Turn: In "Mini-Maximum Trouble", he "laughs in the face of justice" because water messed up his personality chip. He organizes a series of "accidents" for Fred, kidnaps him, and nearly kills the whole team. Luckily, Fred subdues him, and Hiro fixes him in the end of the episode.
  • Flight: Just like Baymax, Mini-Max's armor allows him to fly.
  • Foil: Whereas Baymax is quiet and built to help heal people, Mini-Max is bombastic and built to prevent as much property damage that Fred could cause.
  • Hyper-Competent Sidekick: It's made blatantly obvious that Mini-Max is nowhere near as destructive as Fred. Justified as Hiro created Mini-Max as damage control because Fred keeps causing property damage.
  • Kid-Appeal Character: Mini-Max is a smaller version of Baymax, and his comedic Large Ham personality and vow to protect the city from foes definitely makes him endearing.
  • Large Ham: Hiro seemed to specially design Mini-Max to be just as crazy and eccentric as Fred.
  • Laughably Evil: During his brief stint as a villain in "Mini-Maximum Trouble", he is as evil as he is hilarious.
  • Light Is Good: Just like Baymax, Mini-Max is all white and an ally.
  • Monster of the Week: He accidentally becomes the antagonist of "Mini-Maximum Trouble" after being damaged by water. Luckily, Hiro has him fixed and now makes Mini-Max waterproof so it doesn't happen again.
  • Morality Dial: In "Mini-Maximum Trouble", it's revealed that if damaged by water, Mini-Max's personality chip can change from good to evil.
  • No Indoor Voice: Due to his Large Ham personality, he is constantly shouting. And if you think he can't scream louder, he can.
  • No Water Proofing In The Future: He gets easily damaged by water, despite the franchise happening in 2032. Deconstructed in "Mini-Maximum Trouble" when water messes up his personality chip, and he turns evil as a result. After Fred subdues him, Hiro fixes him and now makes him waterproof.
  • One-Man Army: When temporarily turned bad, the team struggles to catch up and get easily subdued by Mini-Max.
  • Pint-Size Powerhouse: Mini-Max is far stronger than his small appearance would suggest. Justified as Hiro based his design off of Baymax who is stated to be able to lift 1,000 pounds.
  • Plucky Comic Relief: Invoked by Fred.
  • The Pollyanna: Played for Laughs. Mini-Max is always excessively cheerful, even as he tells Fred that he have blown his mind (literally).
  • Promotion to Opening Titles: Season 2 adds him to a few shots in the opening.
  • Robot Buddy: Fred's own personal one.
  • Sidekick: Acts as one for Fred... Sort of. He's actually more there to keep Fred out of trouble.
  • Status Quo Is God: He commits a Face–Heel Turn after his personality chip gets damaged, but once stopped and fixed by Hiro, Mini-Max becomes good again.
  • Running Gag: Villains tossing Mini-Max against a nearby wall after Mini-Max vows to stop them.
  • The Sixth Ranger: The seventh ranger to Big Hero 6.
  • Theme Naming: Has "Max" as part of his name, like Baymax and Skymax.
  • Visual Pun: In "Supersonic Sue":
    Mini-Max: [to Fred] You have blown my mind! [Mini-Max's head catches fire]
  • Weak, but Skilled: While he's a Pintsize Powerhouse, Mini-Max's short stature can be problematic as he is often tossed aside easily and down for the count afterwards.



Voiced by: Dee Bradley Baker
Appearances: The Series (debut: "Mr. Sparkles Loses His Sparkles")

Six remote-controlled robots created by Hiro to deliver the team's suit.

  • Abnormal Limb Rotation Range: Their "head" (which is only their eye) can turn 180°. Justified, since they're robots.
  • Colour-Coded for Your Convenience: Not only are the Skymaxes the same color as their member's color motif, they also have a symbol for each team member:
    • Hiro: Purple with a microbot symbol.
    • Baymax: Red with his own face as a symbol.
    • GoGo: Yellow with a mag-lev disc symbol.
    • Honey Lemon: Pink with a chem-ball symbol.
    • Wasabi: Green with a plasma blade symbol.
    • Fred: Blue with a monster eye symbol.
  • Cute Machines: Their appearances along the high-pitched beeping sounds they do is too adorable.
  • Cyber Cyclops: They have only one eye and are robots on the heroes' side.
  • Flight: They can fly with rockets and get to the team's location to hand them their gear with the press of a button. The original Skymax used his rockets to save Mochi from getting blasted into space.
  • Silent Snarker: The Skymaxes are able to be offended, as one seems offuscated Hiro said he missed Baymax while riding one to get his energy amplifier. The original Skymax also shook his head frantically when Fred asked if he came with a washing machine device.
  • Single Task Robot: They can only deliver the team's suit when ordered to via cellphone (though the original Skymax was also used to rescued Mochi from Mr. Sparkles). However, in "Countdown To Catastrophe", Hiro uses his Skymax to get to the highlight and deactive his energy amplifier.
  • Theme Naming: Has "Max" as part of his name, like Baymax and Mini-Max.
  • Tin-Can Robot: While Baymax and Mini-Max are made out of white vinyl, the original Skymax that rescues Mochi is metallic. It gets downplayed when the proper Skymaxes get added with the team's colors.
  • The Unintelligible: Contrary to Baymax and Mini-Max, they don't speak, they can only do beeping sounds.


Voiced by: Zehra Fazal
Appearances: The Series (debut: "Hardlight")

The virtual assistant of Big Hero 6's new base.

  • Artificial Intelligence: She's a virtual assistant that activates the secret lair through voice recognition.
  • Benevolent A.I.: The artificial intelligence system of Big Hero 6's new base who greets the team when they enter their lair.
  • Distaff Counterpart: She doesn't have a physical body, but her appearance on the screen is Baymax's face, even if Basemax's voice is female.
  • The Smurfette Principle: The only female invention of Big Hero 6 that ends with "Max".
  • Theme Naming: The fourth invention that ends with "Max".
  • Tomboyish Name: Sort of. Her name ends with "Max".


Happy face
Battle face

Appearances: Big Hero 6 | The Series

Hiro's bot that he uses in the botfight competitions.

  • Badass Adorable: A cute robot invented by Hiro that can dissemble robots almost ten times its size.
  • Beware the Silly Ones: Exploited by Hiro. He made Megabot look silly and weak on purpose to hide how much of a skilled fighting machine it actually is.
  • The Bus Came Back: Since Hiro started to botfight again in "The Botfighter" (part of being undercover), Megabot returns.
  • Brainwashed and Crazy: Briefly by Trina, but subverted once Hiro was able to hack control back of Megabot and use it to defeat Trina's robot.
  • The Cameo: Before having another prominent role in "The Bot-Fighter", Megabot appears on Hiro's desk in his room and in his locker.
  • Chekhov's Gun:
    • His design inspires Hiro to create the microbots, which go on to inspire the design for the nanobots used to cure the real Liv Amara.
    • One of his magnets falling on Hiro's foot is what sets Baymax to activate and the movie's intrigue to start.
  • Cute Machines: Even with his battle face, he's adorable.
  • Dark Is Not Evil: He's mostly black, but he's a good robot due to being controlled by Hiro.
  • Detachment Combat: He can detach and reattach himself and can destroy his opponents similarly to a boa constrictor by tightening himself around them.
  • Everything's Better with Spinning: He can rotate his limbs to give him further speed.
  • Eye Beams: In "The Bot-Fighter", Hiro upgrades Megabot with laser eyes that only work with the "battle face".
  • Fragile Speedster: He's rather small and easy to hit, but you gotta catch him first because he's really fast.
  • Ironic Name: "Mega" means "huge", while Megabot is small in size. Subverted in that each of its pieces is larger than an individual piece of the microbots and nanobots.
  • Jekyll & Hyde: Played for Laughs; Megabot has a happy face, and once fighting starts, his face rotates to a "battle" face, which gives a devious grin.
  • Magnetism Manipulation: Megabot is principally made out of magnets, in which he can easily assemble and dissemble himself.
  • Perpetual Smiler: He either has a happy smile or a devious grin. Justified, since the facial expressions are painted on his face.
  • Pint-Sized Powerhouse: He intentionally looks small and pathetic in comparison to the large, intimidating battle bots of the San Fransokyo gambling rings, but dismantles Mr. Yama's larger bot with ease.
  • Pre Ass Kicking One Liner:
    Hiro: Megabot... destroy!
  • Red Is Heroic: Even if the red face is during the part where he attacks, Megabot is controlled by The Protagonist Hiro Hamada.
  • Remote Body: To Hiro.
  • Three-Point Landing: Picture above as Megabot defeated Little Yama.

San Fransokyo Institute of Technology Faculty and Other Students

    Robert Callaghan 

Professor Robert Callaghan
"We push the boundaries of robotics here. My students go on to shape the future. "'

Voiced by: James Cromwell
Appearances: Big Hero 6 | The Series

The owner of a science institute and Tadashi's mentor, he has made major achievements in the field of robotics. He encourages Hiro to attend the institute and dissuades him from selling his microbots to Alistair Krei.

  • The Ace: Callaghan is a brilliant and gifted scientist and teacher, and is famous In-Universe for developments in both engineering (Callaghan actuators) and robot programming (Callaghan's Laws of Robotics).
  • Big Bad: He was the one who stole Hiro's microbots and faked his death to get revenge on Alistair Krei, and eventually revealed as Yokai.
  • Brainy Brunette: A picture of him twenty years ago from "Mini-Max" reveals that he had brown hair in his youth.
  • Broken Pedestal: To his students and Hiro when it is revealed that he is Yokai.
  • The Bus Came Back: He comes back in the series to give Hiro information about Professor Granville while having what appears to be the start of a redemption arc.
  • Canon Foreigner: He was made specifically for the film adaptation.
  • Cool Teacher: Tadashi's teacher and mentor and head of the school robotics program. He also encourages Hiro to do something more productive with his intelligence.
  • Cynicism Catalyst: Abigail's apparent death by the portal was what caused Callaghan to become Yokai in his desire to avenge her.
  • Evil All Along: He was already planning his revenge on Krei when we were introduced to his character.
  • Ex-Big Bad: As Yokai, he is the Big Bad of the movie. In the series, Callaghan is shown to be in prison, regretting his actions and cooperating with Hiro when the latter needs information from him.
  • Foil: He and Krei are explicitly set up as foils at the expo, with Krei wanting to profit off of Hiro's invention and Callaghan trying to persuade Hiro to use his talents for something more. This sets up the reversal when it's revealed that Callaghan is actually Yokai.
  • Foreshadowing: When he warns Hiro not to sell his invention to Alistair Krei, he does so in a surprisingly condescending manner towards Krei. This foreshadows the extreme vengeance he holds towards Krei for causing his daughter's supposed death.
  • Heel–Face Revolving Door: Started as a good teacher and father until the "death" of Abigail at the hand of Krei Tech's experiment caused a Face–Heel Turn, before committing a final Heel–Face Turn once he realizes the consequences of his actions and regrets them.
  • Heel Realization: In the series, when Hiro visits him in prison, Callaghan is very regretful of what happened to Tadashi, and while he knows Hiro isn't happy to see him again, all that matters to him now is that Abigail is back, alive and well.
  • Irony: He became Yokai to get revenge on Krei whom he believed caused his daughter's death. His intention was to make Krei watch as everything he built disappeared. When it turns out she's still alive and is rescued, his own criminal actions have ensured they will be separated by a prison sentence and his reputation is in ruins. His daughter will awaken to find that everything he built has disappeared. His expression when they take him away even says as much.
  • Last-Name Basis: Is called Professor Callaghan or simply "Callaghan". Krei is the only person to call him by his first name, Robert.
  • Manipulative Bastard: Convinced Hiro not to give his microbots to Krei Tech only so he could steal them for his Evil Plan.
  • Meaningful Name: "Callaghan" is an Irish name meaning "bright-headed". His name Robert also means "fame-bright". Both tie with the fact Callaghan was a bright man with an impressive career, before he threw it all away and let revenge consume him.
  • Mr. Exposition: In the series' episode "Mini-Max", Hiro visits Callaghan in jail where he gives Hiro, and to the audience as well, key informations about Professor Granville and her former star student, Obake.
  • My God, What Have I Done?: His face as he gets arrested and watches Abigail get embarked into an ambulance shows nothing but regret, as he understands all his actions were for nothing. In "Mini-Max" he even gives a genuine apology to Hiro for what happened to Tadashi because of him.
  • My Greatest Failure: Reconstructed. At first, Callaghan dismisses Tadashi's fate and calls it his own mistake. But as he's being arrested and realizes his action was All for Nothing, he seems remorseful and in "Mini-Max", gives a honest apology to Hiro for Tadashi's demise.
    Callaghan: I know it's not enough... but I'm sorry.
  • Pet the Dog: Gives a genuine apology to Hiro for what happened to Tadashi because of him. He knows it's not enough, but he's clearly regretful.
  • Redemption Demotion: Callaghan gets the start of a redemption in "Mini-Max" while he's in jail for probably a long time.
  • Reed Richards Is Useless: Averted; in the movie, Hiro flips out when he first meets Callaghan and notes Callaghan's achievements in the field of robotics, such as Callaghan's Laws of Robotics. This seems to imply that he was a pioneer in A.I. development in the movie world.
  • The Reveal: He's Yokai, and he faked his death and stole Hiro's invention in order to get revenge against Alistair Krei for causing his daughter's death.
  • Sacrificial Lamb: He dies in the same fire that kills Tadashi. Subverted as he faked his death.
  • Secret Keeper: After the events of the movie, he is one of the few people knowing Big Hero 6 Secret Identities, and he doesn't tell anyone.
  • Silver Fox: His hair has turned grey for a while, but he doesn't look older than his mid-fifties.
  • Sir Not-Appearing-in-This-Trailer: He's absent from all the trailers save for a split second in this TV spot. Major subversion, as he has appeared since the first official trailer as Yokai.
  • Start of Darkness: His daughter Abigail disappearing and supposedly dying in that portal was what drove him to villainy.
  • Two Aliases, One Character: Professor Robert Callaghan and Yokai are one and the same.
  • Unreliable Expositor: Callaghan when saying that Krei "cuts corners" with science. From what the video footage shows, if the reading had been serious, the general less demanding and Abigail less enthusiastic, he would have halted the experiment.
  • Villain Has a Point: Despite his cruelty in telling Hiro that Tadashi's death was his own mistake, he is still somewhat correct in saying so, as Tadashi chose to run into the flaming SFIT building by himself, thus resulting in his death.
  • Walking Spoiler: He dies in the fire... no, wait, he doesn't. Actually, he fakes his death and steals Hiro's invention, and he is the Big Bad dead set to destroy Alistair Krei whom he deems responsible for his daughter apparent death.
  • A Wolf in Sheep's Clothing: Even as Callaghan was planning his revenge, he was still seen as a kind teacher on the outside.

    Grace Granville 

Professor Grace Granville
"Students needs limits. Even geniuses."

Voiced by: Jenifer Lewis
Appearances: The Series (debut: "Baymax Returns")

The new dean of students at San Fransokyo Institute of Technology after Callaghan's arrest.

  • Action Survivor: While not an Action Girl per-say, Granville makes up for her lack of fighting skills with running, in which she excels at and doesn't even get tired as she's being chased.
    Professor Granville: I may be bad at fighting, but I'm really good at running!
  • A Day in the Limelight: "Seventh Wheel" mainly revolves around her not respecting her limits towards the team and rescuing them from Momakase.
  • Adorkable: Her hidden Genki Girl side that she lets out by moments make her extremely endearing.
  • Affectionate Nickname: Karmi calls her "Professor G". Surprisingly, Granville doesn't mind it.
  • Alliterative Name: Grace Granville.
  • Attack! Attack... Retreat! Retreat!: She tries to fight against Momakase while rescuing her students, only to realize she's a noob fighter against a trained ninja and decides that running away from her is her best skill.
  • Badass in Distress: Despite holding against Momakase for quite some time, she eventually neutralizes Granville and is about to be finished off by the chef, only for Big Hero 6 to stop her just in time.
  • Badass Teacher: In "Seventh Wheel", Granville goes against Momakase to rescue her students who have been held captive by the chef. While not considering herself a fighter, she's able to distract Momakase long enough while Baymax go finds the team by running from her without getting tired. Just Granville standing up to Momakase to save her students is pretty badass in itself.
  • Beneath the Mask: Underneath her serious, no-nonsense mask, Professor Granville is surprisingly a repressed Genki Girl. She actually used to be a straight exemple when she taught at SFIT twenty years ago, as Wendy Wower inspired her TV character from Granville herself. Her hidden excitable side shows by moments, like "Rivalry Weak", "Big Problem" and "Seventh Wheel".
  • Berserk Button: Slackers. She can get a little testy when rules are broken, but this is more of a Downplayed Example as she is able to control her temper quite well.
  • Big Damn Heroes: Pulls one on Momakase who held Big Hero 6 hostage in her pantry.
  • Black Boss Lady: She has dark skin, and as the no-nonsense dean of SFIT, she is the authority figure Big Hero 6 most frequently interacts with.
  • Boyish Short Hair: Has her hair cut short in a pixie cut.
  • Brainy Brunette: Has dark brown hair and is a brilliant scientist and teacher at SFIT.
  • Character Development: She learns to be much more honest as Season 1 goes on, particularly with Hiro, who she ends up having something of a bond with.
  • Cool Teacher: A Reasonable Authority Figure? Check. Hides an excitable side under her serious demeanor? Genre Savvy? Check. Badass? Check.
  • Drill Sergeant Nasty: Shows shades of this in "Rivalry Weak" towards Wasabi and Fred in order to prank SFAI, and in "Seventh Wheel" when putting the team through an exercise regimen. All Played for Laughs, of course.
  • Demoted to Extra: She has far less appearances in Season 2 due to the Obake arc being done with (though she did have A Day in the Limelight in "Seventh Wheel").
  • Expository Hairstyle Change: Back in the day when she taught at SFIT, she had long curly hair reaching under her nape. Twenty years after Obake's accident and when she started teaching again, she wears her hair in a short pixie cut, indicating her manners of teaching and the person she was back in the day have changed.
  • Foil: To Callaghan. While Callaghan was generally lax and seemed to be a Reasonable Authority Figure, Granville is more no-nonsense. But while Callaghan ultimately succumbed to his own anger and ended up not caring for any of his students, Granville is only tough on her students because she wants them to be at their best.
  • Fragile Speedster: Granville makes up for her lack of fighting with her incredible running speed and her stamina.
  • Genki Girl: She used to be a straight example 20 years ago, and even inspired Wendy Wower's TV Character. But after a terrible lab accident injured one of her students, she quit her job in guilt and once she came back in the present day to replace Callaghan, became much more severe and uptight for her students' sake. It's later reconstructed as loosening up around the team makes her inner excitable side come out more often, like when she was a novice teacher.
  • Genre Savvy: "Seventh Wheel" shows that Granville actually knows a lot about supervillains' tactics, and uses this to help Big Hero 6 against Momakase. Though her help slowly becomes smothering.
  • Hates Being Touched: Implied. Let's just say she's not a hugger.
  • Hidden Depths: "Rivalry Week" reveals that she's actually quite a prankster, to the point she not only allows the group to pull a prank on SFAI, she actually joins in so that they don't get pranked first.
  • Horrible Judge of Character:
    • Subverted with Karmi — at first, it seems that she's fallen for Karmi's "nice girl" routine, but it later turns out that the reason she wanted Hiro and Karmi to hang out together was actually more for Karmi's sake rather than Hiro's sake.
    • Played straight with Liv Amara. Granville has no idea who she truly is and sees her as friend.
  • Jerk with a Heart of Gold: She tends to be strict on her students, scolding Hiro for repeatedly violating school policy by breaking into Tadashi's former lab when it is off limits to first semester freshmen. However, she lectures him calmly and wants him to live up to his potential, praising him for his work efforts in class at one point. In fact, the times she lectures Hiro, she is patient and is determined that he not screw up his future. When Hiro fake cries, she is baffled and even tries comforting him (albeit reluctantly), even enduring a hug from him. Overall, she is a Reasonable Authority Figure.
  • The Mentor: Acts like one towards Hiro. Makes sense when you realize he reminds her of her former star student she feels like she let down because she didn't give him limits.
  • My Greatest Failure: The accident that left her student Bob Aken grievously injured. While she had nothing to do with the accident, she felt personally responsible due to her lack of supervision on her students, which consequently caused Bob to conduct more and more reckless experiments. This was what caused her to resign.
  • Mysterious Past: Used to be a teacher at SFIT in the past, and left for reasons not explained yet, not mentioning that she used to be at the school when coming back, and is in a picture with a boy who appears to be a young Obake.
  • No Celebrities Were Harmed: Her voice and demeanor is most likely based on that of Lynne Thigpen from Where in the World Is Carmen Sandiego?.
  • Not So Above It All:
    • "Rivalry Week" reveals she's just as enthusiastic about stealing SFAI's Lenore Shimamoto statue as the school's students. She even ropes Wasabi and Fred into guarding SFI's dining hall, making them wear camouflage clothes and use whistle signals, while she wears full-on spy gear.
    • In "Seventh Wheel", Granville is about to fly on Baymax's back to save the team. Before blasting off, Baymax tells her "Don't look down.". As soon as Baymax is off the ground, every part of Granville's stoic nature vanishes.
    Professor Granville: I LOOKED DOWN! I LOOKED DOOOOWN!
    • Falls just as hard as everyone else for the Mayoi's cuteness in "Something Fluffy", to Hiro's dismay.
  • O.O.C. Is Serious Business:
    • She gets all The Knights Who Say "Squee!" when Liv Amara visits SFIT.
    • Played much more seriously when she discovers that Hiro proposed a power amplifier for his final project, where she's much more livid and emotional and outright rejects his proposal. Turns out her former student Bob Aken attempted the same before, only for the experiment to backfire horribly.
    • When she meets her former student Obake, she's uncharacteristically emotional.
    • She appears rather broken when she explains to Hiro Karmi's parents decided to have her move out of the city.
  • Pet the Dog: Take any scene with her and apply this trope: first scene, she is sympathetic towards Tadashi's death, saying that he was an excellent student. She describes herself as "tough, but fair". She praises Hiro for his work efforts so far in a meeting and even decides to allow him access to Tadashi's former lab, thinking that it would help him.
  • Reasonable Authority Figure: She may seem strict, but it's to be expected considering her position. And with that, it comes with rationality, and she can be playful at times. For example, she tries to get Hiro and Karmi to befriend each other since the latter is friendless. And while she shows that she was somewhat irritated with Hiro spying on her in "Mini-Max", she understands and takes a moment to explain why she lied, apologizing to Hiro for not being honest since it caused more trouble than it was worth.
  • Rummage Sale Reject: In "Seventh Wheel", Granville has no time to build herself an armor so she ends up mixing up parts of Big Hero 6's armors into one suit. (Honey's helmet, Wasabi's left gauntlet, Gogo's chest plate, and Hiro's pants and right gauntlet).
  • Secret Secret-Keeper: She reveals to Big Hero 6 that she knew who they were the entire time in "Countdown to Catastrophe".
  • Sixth Ranger: Becomes the Seventh Ranger to Big Hero 6 in the episode "Seventh Wheel", where she gives helpful (though pushy) advice to the team and even goes to rescue them from Momakase. She chooses to resign by the end of the episode.
  • Stern Teacher: Tough, but fair. She's mainly tough on her students, Hiro in particular, because she wants them to succeed while still respecting their limits. She especially has a soft spot for teen geniuses, as seen with Hiro, Karmi and Bob Aken, whom she's determined into leading to the right direction.
  • Tragic Keepsake: Why does she have a dangerous energy amplifier in her office? It's the one that Bob Aken made that caused his accident.
  • Unskilled, but Strong: She doesn't have any fighting skills, but she has a good stamina and can easily escape Momakase and leave her hanging long enough while Baymax frees the rest of Big Hero 6.
  • Unwanted Assistance: The whole premise of "Seventh Wheel". While she means well and starts out helpful, Granville quickly begins to overstep her bounds, putting the team on a exercise regimen, planning their missions for them, and "fixing" Wasabi's plasma blades, causing them to make a really annoying sound when activated.
  • Victory by Endurance: While Granville doesn't stand a chance against Momakase, she keeps up against her by running from her with her unlimited stamina, which keeps Momakase focused on trying to get to her while Baymax frees the team. When she does get caught however, the team rescue her in time before Momakase can kill her.
  • Wrench Wench: She's a thermodynamics teacher, but she also teaches (or at least taught) robotics, in which she showcases herself to be quite skilled in by how she fixes Baymax without problem in "Seventh Wheel". She also created and built the security system spider bots.

Voiced by: Haley Tju
Appearances: The Series (debut: "Issue 188")

The second-youngest student attending San Fransokyo Institute of Technology, right after Hiro. She's a biotechnology major who specializes in the study of virology and bacteriology.

  • Abhorrent Admirer: Downplayed. While not hideous or obsessive, Karmi's crush on "Captain Cutie" makes Hiro extremely uncomfortable (justified, since she hates his real identity).
  • Action Survivor: She's the usual Damsel in Distress, though she shows herself to be quite able to fend for herself in "Big Problem" where she takes down Orso Knox BY HERSELF.
  • Adorkable: Shown particularly whenever she's excited by something Bio Tech-related or Big Hero 6 related (especially in regards to her beloved "Captain Cutie".) She also loves cute stickers and puts them on her virus' containers.
  • Ambiguously Brown: Her ethnicity has not been explicitly expressed in the show yet. Considering the Big Hero 6 franchise's tradition to have Actor-Shared Backgrounds, it's plausible she might be partially based off of her voice actress, who is part-Indonesian and part-Chinese.
  • Alliterative Name: The name of her fictionized superhero persona, Lab Lady.
  • Always Second Best: The reason why she's jealous of Hiro is because he stole her "thing", which was being the youngest genius at SFIT before his arrival. It obviously implies she feels threatened by his genius and potential.
  • Ascended Extra: She was a recurring character in Season 1, with only 3 episodes where she was in the center of the story (most of the time, not related to the Obake arc). Now in Season 2, Karmi is more prominent due to unknowingly working for the main antagonist and helps the team against the monsters Liv creates.
  • Ascended Fangirl:
    • She got to be rescued by "Captain Cutie" and meet him several times.
    • Her ideas from her fanfiction (Gogo vertically skating, Honey and Fred making an ice shower, Baymax's overdrive mode) are actually used by the team.
    • She idolizes Liv Amara, and got to know her personally and intern at her company Sycorax. Unfortunately for Karmi, it's exploited by Liv.
  • Ascended Fanon: In-Universe, the team actually finds that the tricks that she suggested in her fanfiction of them work pretty well, like GoGo skating vertically up walls and Honey Lemon and Fred creating ice showers. Hiro also upgrades Baymax with his own "Overdrive Mode."
  • Asian Rudeness: When meeting Hiro, she tends to treat his naivety with a condescending attitude of disdainful scorn, and teases him out of spite and enjoying seeing him humiliated, currently unaware that Hiro and "Captain Cutie" are the same person. The rivalry continues as Karmi and Hiro become Liv Amara's and Alistair Krei's respective interns.
  • Aww, Look! They Really Do Love Each Other: Despite the differences she has with Hiro, she shows genuine concern over his health. The first time is seen when Hiro chokes on food in "Baymax and Hiro", and the second time in "Prey Date" after Hiro is "kidnapped" by Orso Knox. Finally in "City of Monsters", Hiro and Karmi put their differences aside to work on her project together, and it ultimately culminates in Hiro telling a transformed Karmi that he's her friend, and that he cares about her.
  • Badass Bystander: Karmi's latest invention, which caught the eye of Liv Amara, much to Hiro's dismay, becomes instrumental in taking down Orso Knox. What makes her more badass is the fact that she put them on herself.
  • Baleful Polymorph: Is eventually turned into a monster by Liv in "City Of Monsters," and is forced to attack Hiro.
  • Belligerent Sexual Tension: With Hiro (when he's not in superhero gear).
  • Beneath the Mask: Underneath her quick temper and stinginess, actually hides a kind-hearted, passionate girl who always chooses the right thing to do.
  • Berserk Button: Killing her viruses. She's very attached to them.
  • Big Damn Heroes: Saves Liv Amara right before she can get attacked by Orso Knox by applying her nano-receptor stickers.
  • Birds of a Feather: Seems to get along pretty well with Honey Lemon, since the two of them are science-loving Adorkable Genki Girls. Honey Lemon even refer to her and Karmi as "bio-besties".
  • Bitch in Sheep's Clothing: She's very sweet and polite in front of Granville, but turns on a dime the moment she is left alone with Hiro. Hiro realizes that Granville knew about the false niceties already, and that Karmi was the person that needed to learn to socialize. By "Failure Mode" she seems to have dropped this by how she openly insults Hiro and films humiliating videos of him in front of Granville.
  • Blue Is Heroic: Her fanfiction alter-ego, Lab Lady, is all dressed in blue.
  • Bound and Gagged: In "Fan-Friction", Karmi gets kidnapped by Momakase and taken to Akuma Island, and Hiro finds her tied on a chair and her mouth gagged with a rag.
  • Brainwashed and Crazy: After Liv mutates her in "City of Monsters", Karmi goes wild and kidnaps Hiro, with the intention of bringing him to Liv. She luckily gains back control.
  • Brainy Brunette: Has brown hair and was the youngest teen genius in the history of SFIT to attend the school before Hiro came along.
  • Butt-Monkey: A mild example - something frustrating always seems to happen to her every time she appears (having a beloved virus die, having embarrassing snapshots taken of her, getting tricked into being locked out of a seminar, being the accidental victim of Hiro's new super-strength twice, getting kidnapped by Momakase, etc.) The end of "Fan Friction" and all of "Big Problem" gives her a break, though.
  • Camera Fiend: Takes a lot of pictures of Hiro in superhero gear, as well as embarassing ones of his real identity.
  • Character Development: Karmi's development that occurs late in Season 1 and even more in Season 2 is about her learning to open up more to people and be less aloof and hostile, particularly in regards to Hiro whom she finally befriends in "City of Monsters".
  • Character Narrator: She narrates her own fanfiction in "Fan-Friction".
  • Chekhov's Gun: Her electric rose project from "Countdown To Catastrophe" comes in handy in "City of Monsters" in order to cure the real Liv.
  • Child Prodigy: If she's a Teen Genius like Hiro, it's implied that like him, her genius was discovered at a young age as well.
  • Cloudcuckoo Lander: Downplayed. Karmi is rather down to earth, but still baby-talks to her viruses and says they're her friends. She is quick to be angered if anyone (Hiro, in that case) questions about the "weirdness" of it.
  • Companion Cube: Karmi talks to her viruses, puts cute stickers on their petri dishes and considers them her friends. "City of Monsters" shows she has a plush chicken pox virus toy that she cherishes like a teddy bear.
  • Curb-Stomp Battle: She at first receives one from Chris while the two fight as mutants, but later the table turns for her when Liv deactivates his chip and he's turn back into his normal human appearance and she inflicts one right back at him, though off-screen.
  • Damsel in Distress: Just like Marys Iosama before her.
  • Deadpan Snarker: Has her moments. Mostly reserved at Hiro.
    Hiro: [about the Mayoi] Liv created these things, and even if they look cute, they're monsters!
    [Karmi looks at a Mayoi affectionately licking a student's face.]
    Karmi: Yeah. I'm terrified.
  • Death Glare: She gives one to Hiro in "Prey Date" after Fred drops all the petri dishes containing her viruses, thus killing them.
  • Decomposite Character: Seems to be based of Marys Iosama from the comics, who was a teen genius Hiro's age. Though Karmi is a tad older than Hiro, a Tsundere and Marys's Nice Girl personality and friendliness have been given to Megan.
  • Defrosting Ice Queen:
    • She starts showing this a little following Hiro covering for her in Granville’s office. Emphasis on "little" as she quickly shushes Hiro in getting a notification on his secret hero identity.
    • Shown again in "Baymax and Hiro" when she appears to show concern when Hiro choked while Baymax was feeding him in his overpowered mode. Immediately after taking her phone out and recording a video out of amusement.
    • "Prey Date" has a moment where she genuinely worries about Hiro's health when he gets "kidnapped by Orso Knox", and later in the cafe when she's alone with Hiro.
    • "City of Monsters" has her and Hiro finally fully start to warm up to each other, after working on the cure for the Parasyns together. They go from snarking insults to giving unambiguous compliments and bonding, including Karmi giving Hiro warm words about Tadashi.
  • Determinator:
    • Despite Liv refusing and Orso Knox being loose into Sycorax, nothing stops Karmi from trying to find a cure for him.
    • In "City of Monsters", when Karmi is mutated, she protects Hiro from Chris, and does not stop fighting him despite Chris clearly having the upper hand. She was ready to fight until she couldn't for Hiro.
  • The Dog Bites Back: During her fight with Chris, Monster Karmi was easily overpowered due to Chris being more skilled and strong than she was. The instant the real Liv deactivates his chip and he turns back to normal, Karmi, still in monster form, beats Chris to a pulp for both attacking her and wanting to harm Hiro.
  • Et Tu, Brute?: Karmi realizes Hiro was right about Liv since she implanted her with a mutation chip off-screen.
  • Extreme Doormat: When it comes to Liv, who manipulates her for her own gains. Hiro is aware of this and also uses this to his advantage to get infos on Orso Knox.
  • Fangirl: To Big Hero 6, especially "Captain Cutie". Also of Liv Amara.
  • Fighting from the Inside: Hiro begs a mutated Karmi to remember who she is and that he cares about her. Liv keeps ordering Karmi to kill Hiro via her phone, and we see Karmi grab her head and growl, fighting for control of her body. She wins, as no matter how many times Liv orders to kill on her phone, she has now gotten rid of Liv's control and now protects Hiro from further threats like Chris.
  • Flower Motif: Hers appears to be the rose. Not only is her electricity powered rose her best invention, the rose is symbolic to Karmi's character: she's passionate and devoted (towards her her work), loving (towards Captain Cutie), and underneath her thorns, hides a truly beautiful heart.
  • Foil: Her interest in germs and pathogens — which can hurt people — contrasts with Hiro, Tadashi, and Baymax's focus on healthcare and rescuing people.
  • Forced into Evil: Liv implants a mutation chip into her neck and turns her into a monster so she can kidnap Hiro and bring the nanobots to her.
  • Friendless Background: According to Gogo, Karmi (though certainly very intelligent and a good student) doesn't really have any friends (other than her viruses, of whom Karmi's very proud of) and, up until Hiro came along, pretty much the only thing she had going for her was the fact that she was the youngest student in the history of SFIT. And at the end of her debut episode, it turns out that Granville's actually fully aware that Karmi's not as nice as she likes to make people think she is and that the reason she wanted Hiro and Karmi to hang out together was for Karmi's sake and not Hiro's.
  • Genki Girl: When excited about something she has a passion for (like Big Hero 6 or anyting bio-tech related), Karmi has a sparkle in her eye and acts like a little kid on Christmas day, which makes her more endearing.
  • Giver of Lame Names: While one or two of the codenames she gives the Big Hero 6 members in her fanfiction aren't that bad, like Gogo's "Speed Queen", Honey Lemon and Hiro are "Tall Girl" and "Captain Cutie", respectively.
  • Grade Skipper: Implied. She's a Teen Genius like Hiro, and attends SFIT at 16 years of age. Hiro said he skipped a couple of grades, so Karmi must've done so as well.
  • Green-Eyed Monster: She's jealous of Hiro for stealing her place as the youngest genius in history to attend SFIT. Ironically, Hiro is also jealous her and her internship at Sycorax.
  • Hair-Trigger Temper: When Hiro is around, anyway. She grows out of it thanks to Character Development.
  • Hates Being Touched: Implied; Karmi says to Honey that she's not much of a hugger and seemed shocked to be hugged by Honey. In "City of Monsters", when Hiro sees Liv/Di implanted a chip in her neck and tried to get if off, Karmi's first reflex is to immediately shove him away from her. On the other hand, she has no problem hugging Captain Cutie at the end of "Fan Friction".
  • Hates My Secret Identity: Karmi's in love with superhero Hiro, but really despises Hiro Hamada the student. Averted by "City of Monters" when Hiro and her become friends (and still loves Captain Cutie).
  • Hazmat Suit: She wears one while working with the most dangerous of her viruses.
  • Heroic Willpower: After Hiro gives her an I Know Youre In There Somewhere talk when she's in monster form, she manages to get back to her senses, and was the only mutant that managed to slip away from Di's control. All thanks to The Power of Friendship.
  • Hidden Depths: "Issue 188" shows that Karmi has some artistic ability sketching Hiro in his superhero form in one of her notebooks. Additionally, while her lyrics need work, "Small Hiro One" shows that Karmi actually has some singing skills and can play the ukulele pretty well.
  • Hot-Blooded: Extremely excited over virology and biotech, and Hiro discovers it's better not to go between her and her work.
  • Horrible Judge of Character: Not only does she think Hiro is only up to annoy her and steal her spotlight as the youngest genius on campus, she has no idea her so called "BFF" Liv Amara is a manipulative sociopath.
  • Hypocritical Humor:
    • In "Prey Date", after Orso Knox's containment unit changes from "secured" to "disabled":
    Baymax: Oh, no.
    Karmi: Do not "Oh, no"! I don't want to hear any "Oh, no-ing" from you!
    Hiro Uh, Karmi?
    Karmi [faintly, after she sees Orso Knox has broken out]: Oh, no.
    • After the team has brought Orso Knox back:
    Hiro: So, Karmi, did your serum work?
    Karmi: Yes, but it's not my serum; at Sycorax, we don't like words like "my" or "me". The breakthrough was a team effort... based almost completely on my work.
    • Karmi states that she's not a hugger to Honey in "Nega-Globby". But in "Fan-Friction" she jumps at Hiro to hug him.
  • Iconic Item: Even while working in her lab or on a prestigious gala, Karmi never takes off her red and yellow bracelets.
  • "I Know You're in There Somewhere" Fight: Hiro pulls one on her when she's about to kill him in mutant form. It works, as Karmi now regained control of her mind and protects Hiro from Chris.
  • Insufferable Genius: Downplayed. Karmi is more of a Jerk with a Heart of Gold and while she's hyper-competent in her scientific field, the "insufferable" part is mostly reserved at Hiro's expense. It's also implied that just like Hiro, it's out of insecurity.
  • Jerk with a Heart of Gold: While she's harsh towards Hiro, she has a high sense of morals and shows that she actually cares about him even if she doesn't want to admit it. She's also pretty friendly with Honey Lemon and simply socially-awkward with people she's not familiar with. In "Prey Date", Karmi is determined to save Orso Knox because she wants to prove herself — and because he is still human in need of help.
  • Kick the Son of a Bitch: You can't help but cheer for her when she beats up Chris, even if he was de-powered and her still mutated. First because he's a villain, and second because he previously beat her, threw her around and also tried to attack Hiro. He had it coming.
  • Labcoat of Science and Medicine: Wears a white lab coat in her first appearance and during her internship at Sycorax.
  • Laser-Guided Karma: In "Small Hiro One," she mocks Hiro for not being able to get into SFIT due to his age, but is the first of the students to get kicked out by Trengrove.
  • Long Hair Is Feminine: Has a long ponytail that ends at her bottom of her back.
  • Loves My Alter Ego: She seemingly has no idea that Hiro is Big Hero 6's "Captain Cutie", who she is in love with.
  • Meaningful Name: "Karmi" is derived from "Carmen", which can mean "garden" or "orchard". Karmi studies in biotechnology, which includes all forms of biology and in that case, botany, as Karmi's breakthrough invention is an electricity powered rose.
  • Most Fanfic Writers Are Girls: Writes fanfiction about the team.
  • Motor Mouth: In "Big Problem" when she learns Liv Amara is coming to SFIT.
    Karmi: [fast-paced] I saw Liv Amara's helicopter land, and I had to come and meet her! She is my hero, I love her! Is she here?!
    Baymax: You should breathe, now.
  • Ms. Imagination: Her Big Hero 6 fanfictions are extremely creative and detailed. So much that it actually inspires Big Hero 6 in real life.
  • Naïve Everygirl: Despite being a genius, Karmi is shown to be quite naive. Not only there's the fact she's unaware Hiro and "Captain Cutie" are the same person, she also believed Trengrove right away she had the right to a free ice cream while he was actually kicking her out of his workshop. Also, there's her not believing for a second Liv is behind the monsters and being played by a fiddle by the latter.
  • Nice Girl: After much needed Character Development, she becomes this.
  • The Nicknamer: She's the one who gave BH6 some surnames people who read her fanfiction seems to use as well: Captain Cutie for Hiro, Red Panda for Baymax, Speed Queen for GoGo, Chop-Chop for Wasabi, Tall Girl for Honey Lemon and Flame Jumper for Fred.
  • Nightmare Fetishist: She's studying virology and bacteriology, and seems really attached to them.
  • No Social Skills: Karmi is anti-social, and has never had real friends before.
  • Not So Different: As Baymax notes at one point, Karmi's essentially what Hiro would be like if he didn't have his friends (and replaced robotics with virology). Karmi denies this, but she probably knows it's true and is too proud to admit it.
  • Off Screen Momentof Awesome: The scene of her beating up Chris is not shown (only heard), but you can't help but cheer for her as it happens.
  • One Head Taller: Than Hiro.
  • Only One Name: Her last name is unknown, so she's solely known and credited as "Karmi". Even on her chip at Sycorax, only her first name is written.
  • Painful Transformation: In "City of Monsters", Liv implants a mutation chip into Karmi. Contrary to the characters' mutations, who were gradual, Karmi's is instantaneous and she wails in pain the whole time.
  • Pet the Dog: She finally befriends Hiro in "City of Monsters", after complimenting his invention and sympathizing with Hiro over Tadashi's death.
  • Proper Tights with a Skirt: Wears an orange skirt over black leggings as her everyday outfit.
  • Put on a Bus: After the whole Sycorax and monsters ordeal, Reality Ensues and her parents decide to make her quit San Fransokyo for her safety. Though by the ending of the episode where Karmi continues her fanfiction and it's To Be Continued, it's probably a foreshadowing that it's not the last we see of her.
  • Rapunzel Hair: Her ponytail ends at her waist. Which means if it was to be loose, it'd be even longer.
  • The Rival: To Hiro, as she feels envious that he stole her position of being the youngest student in the history of the school. Hiro isn't interested in a rivalry and would rather they be friends at the very least, but as of "Failure Mode", he starts playing back into the rivalry and it continues even into Season 2.
  • Serious Business: Her work with viruses. It's not a good idea to disturb her while she works...
  • Ship Tease: With Hiro, when he's both in and out of his armor.
  • Shorter Means Smarter: Is barely a few inches taller than Hiro, but smaller than GoGo, and is the second youngest teen genius at SFIT after Hiro.
  • Shrinking Violet: Despite the overly-confidence she gives herself about her genius, she has moments of shyness and vulnerability, like when she enters Liv Amara's office and shyly asks to help cure Orso Knox.
  • Slipknot Ponytail: In "City of Monsters", when Karmi turns into a monster, her hair grows even longer and her elastic snaps, letting her hair wild and loose from the ponytail as she kidnaps Hiro.
  • Smitten Teenage Girl: Is head over heels for Big Hero 6's leader whom she calls "Captain Cutie". She draws him in her notebooks and writes a self-insert fanfiction about their love. Unbeknownst to her, he's actually her rival Hiro Hamada who she despises.
  • Snark-to-Snark Combat: With Hiro, whenever they are in the same room. Since he gives increasingly lame comebacks as he gets too worked up, she usually wins.
  • Stepford Smiler: Her cheerful appearance around Professor Granville is a façade for her feelings at being displaced as the youngest student when Hiro enrolled at San Fransokyo Tech.
  • Sugar-and-Ice Personality: At first, Karmi is aloof, anti-social and harsh towards Hiro, but as the series go on, she shows she has a good heart and her real colors shows an Adorkable girl passioned about science and can be friendly when she wants to (as shown with Liv Amara and Honey Lemon).
  • Teacher's Pet: Professor Granville is the most nice to her compared to other students. Proof is, Professor Granville lets Karmi call her "Professor G", instead of everyone else who has to call her "Professor Granville". Karmi also acts friendly to Hiro only when Granville is around, in order to be seen as an angel by the latter (though only in Issue 188).
  • Teen Genius: Karmi was previously the youngest person ever accepted into SFIT until Hiro came along.
  • Teens Are Short: Is not that taller than Hiro, who is 5'0".
  • Terrified of Germs: Ironically, despite — or perhaps because of — her obsessive devotion to germs and viruses, she is hyper-conscious of the slightest possibility of getting sick, and she runs away the moment Hiro so much as sniffs in her presence. It's also worth noting that while she's somewhat reckless in her growth and containment of deadly viruses, she does her serious work while wearing a full Hazmat Suit.
  • Tomboyish Ponytail: Inverted. Karmi wears her hair in a ponytail but is more of a Girly Girl.
  • There Is No Kill Like Overkill: A variant in "Big Problem". After Karmi puts a bunch of her tranquilizer stickers on Knox, he faints. But when he starts regaining consciousness soon after, she frantically puts on several more to make sure he stays asleep.
  • Trauma Conga Line: "City of Monsters" was not kind on Karmi. She finally realizes how evil Liv actually is despite Hiro's protests, and Liv attacks her and implants a chip off-screen. She then runs away to SFIT, terrified, and warns Hiro. Then she turns into a mutant and is forced to kidnap and attack her new friend. And once it's all over, her parents make her quit SFIT for her safety, and she and Hiro didn't get to say goodbye. We don't see how she copes with it, but it must be a lot.
  • True Blue Femininity: Wears a blue dress for Liv Amara's celebratory gala in "Big Problem"
  • Tsundere: The "tsun" side is shown around Hiro, while the "dere" side is shown around his heroic alter-ego, although it occasionally shows around Hiro as well, especially in Season 2 where she is constantly on the defensive about the notion that she and Hiro are friends or could become friends.
  • Unstoppable Rage: After being mutated by Di, Karmi is extremely violent and basically a new pet of Di that obeys to her every order. And when she finally breaks away from Di's control, she gets EVEN ANGRIER when Chris was gonna harm Hiro, which made Karmi violently attack him to protect her friend.
  • Violently Protective Girlfriend: Downplayed. While Karmi is not Hiro's girlfriend, when she was mutated and Chris tried to attack Hiro on Liv's orders, she snapped, tossed Hiro aside to keep him away and started ruthlessly attacking Chris, with the intention of protecting Hiro from him. No matter how many times Chris beat her, she kept going. When the real Liv turned Chris back to normal, Karmi, who had all of her conscious thoughts, beat Chris up unconscious. Yeah, Karmi grew to really care about Hiro, so don't hurt him if you know what's good for you.
  • What Measure Is a Non-Human?: Zigzagged. Karmi says that Hiro is the pathetic one for having Baymax as a friend, citing that at least her viruses are actually alive.
  • What You Are in the Dark: When she and Hiro are locked in Sub-Level 9 with a feral Orso Knox, Karmi doesn't even want to think about running away. She installs herself in a lab and tries to work on a cure. She's still determinate to help even if Liv says otherwise, and shows concern over Hiro after he gets taken away by Orso Knox.
  • Wrong Genre Savvy:
    • She thinks Hiro is crushing on her solely because he's being polite and wants them to work on their project.
    • She also thinks Hiro is bragging about stealing her spotlight of the youngest teen genius on campus, but it couldn't be more far away from the truth.

  • Meaningful Name: The name "Wendy" was invented by Peter Pan's author J.M. Barrie; the name comes from the word "fwendy" ("friendly") that was said by the young daughter of a friend. In Wendy Wower's case, she's definitely friendly.
  • Nice Girl: Friendly and well-meaning to a fault, even if she's a little weird.
  • Nice Shoes: She has bright pink shoes with purple highlights along with yellow lightnings on the sides, similarly to the Olympian God Hermes.
  • Perpetual Smiler: She's excited and happy, thus she's always smiling.
  • Pink Means Feminine: Wears a pink shirt and shoes.
  • Self-Serving Memory: Wendy says she based her persona on Professor Granville, or rather how she remembers her.
    • Turns out, considering the information we learn about her later on, this interpretation may not have been too off in the past. Though based on Granville's reaction to this herself...Maybe Wendy is just remembering weirdly.
  • We Need a Distraction: Distracts Yama and his goons with her group's baking soda volcanoes while Hiro and Baymax sneaks inside Trevor's workshop.
  • You Gotta Have Blue Hair: Her hair is green. The flashback scene of her youth shows that it was once brown, so she probably dyed it.

    Trevor Trengrove 

Dr. Trevor Trengrove
"Who's jazzed for some science?"

Voiced by: Andy Daly
Appearances: The Series (debut: "Small Hiro One")

An alumni of SFIT that became a famous scientist.

  • Accidental Misnaming: Trevor calls Hiro "Kiro".
  • Alliterative Name: Trevor Trengrove.
  • Behind Every Great Man: Wendy is the one behind the thesis, and Trevor stole it and got all the credit.
  • Brainy Brunette: Seems to be the case considering how big of a scientist Trevor is, but actually subverted as Trevor actually stole Wendy's thesis and slowly reveals himself to not entirely know science and its terms.
    • Played straight in his youth, when he was in Professor Granville's robotics class.
  • Easily Forgiven: Despite not being on speaking terms for many years, Wendy was more than grateful that Trevor gave her back her thesis and will admit to what he did.
  • Fake Ultimate Hero: He stole Wendy Wower's thesis on artificial intelligence, using it to make himself a celebrity and idol among young scientists. He's felt really guilty about it, and after being blackmailed, he decides to give Wendy back her thesis.
  • Heel–Face Turn: Ultimately betrays Yama and gives Wendy back her original thesis.
  • Hot Scientist: Is quite attractive.
  • Inferiority Superiority Complex: Portrays a version of himself that is almost infuriatingly egotistical and self-centered. As the episode goes on, this becomes very clearly not the case.
  • Kick the Dog:
    • Tricking Karmi into getting a free ice cream to kick her out of his workshop, before doing the same to other students.
    • Stealing Wendy's thesis and getting all the credit for it is probably his biggest dick move.
  • Jerkass: Repeatedly kicks anyone out who isn't a physics, engineering, or chemistry major, and in a rather rude and obnoxious way at that.
    • Jerk with a Heart of Gold: Regardless of his actions in his debut episode, it doesn't change the fact that he really does mean well, and deeply regrets his actions towards Wendy.
  • Jerkass Realization: Trevor ended up being a glory-mongering jerk who stole Wendy's thesis, but after all the trouble he was put through with the blackmail, Trengrove does feel bad for it all and decides he will tell the world and give Wendy the credit she deserves in the first place.
  • One-Shot Character: Contrary to Wendy, who appeared in two episodes, Trevor was only seen in "Small Hiro One".
  • Perpetual Smiler: Has a constant fake smile on his face.
  • Plagiarism in Fiction: Trevor stole Wendy's thesis.
  • Took a Level in Kindness: By the end of "Small Hiro One", Trevor betrays Yama and gives back Wendy's thesis to her, stating he had felt guilty about it for long and it's time people knew the truth.
  • The Un-Smile: He has a very creepy grin on his face as he watches the team work.

Other Allies


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

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

"And that's how you monster!"

An affable, but incompetent purse thief that steals Honey Lemon's chem purse and turns into an increasingly competent goo-based supervillain.

However, at the end of Season 1 he has a change of heart after witnessing the full scope of Obake's plan, and ultimately finds his callings as a hero instead - which lasts throughout the rest of the series, even after being framed and branded a criminal again, leaving him a fugitive.

  • 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 he turns back into human, Dibs is happy at first, but soon starts to miss having powers and later, needs to help his friends against Nega-Globby. So he steals Honey Lemon's chem purse again, transforms back into Globby, and swallows his Evil Counterpart, 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.
  • Anti-Villain: As a villain, he is an affable, non-malicious dork looking for his purpose in life in all the wrong places. When he learns of Obake's plan to level the city, Globby realizes just how evil his employer is and promptly defects to the heroes' side.
  • 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.
  • Big Damn Heroes: In "Nega-Globby", he comes out of his 10-Minute Retirement and saves the heroes from the titular monster.
  • Birds of a Feather: After he pulls a Heel–Face Turn, he instantly befriends Honey Lemon. Both are adorkable, excitable cloudcuckoolanders who are devoted to their friends and really love hugs.
  • Blatant Burglar: Before his transformation, Dibs wore a green coat and a black ski mask during his thefts.
  • Blob Monster: After his accident, he turns into an indestructible purple blob that can shapeshift into anything.
  • Buffy Speak: "Quick! Use your thing to stop that thing!"
  • 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.
  • Cuddle Bug: After he becomes a good guy, he envelopes his newfound friends in a hug every five seconds.
  • 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.
    • He can change parts of his body into any element or item, yet never thinks to create and profit off selling rare material.
  • Determinator: In "Failure Mode", despite being a terrible supervillain (or "sub-par villain" as Hiro says), he never stops trying to steal Lenore Shimamoto's "City Rising" painting. Once he learns how to control his powers, he actually succeeds stealing it and defeating Big Hero 6.
  • Didn't Think This Through: When he ate Nega-Globby, he didn't know the latter will remain dormant inside him and eventually try to take control.
  • Dumb Blonde: He's a natural blond, and he's prone to a few ditzy moments. Gradually subverted as he undergoes Character Development.
  • 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 Loved Ones: Even as a supervillain, he cared a lot about his Only Friend Felony Carl. He's the reason Globby pulled his Heel–Face Turn.
  • 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 ultimately 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.
  • Evil Counterpart: As a villain, Globby is this to Honey Lemon. They use the same method of attack (even coming from the same source), they both are adorkable, excitable cloudcuckoolanders.
  • 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. It sticks in Season 2, having fully become a superhero even after becoming a fugitive.
  • 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.
  • I Just Want to Be Normal: In "Nega-Globby", the reformed Blob Monster has trouble finding a job, so he wants to become human again. Honey and Karmi grant his wish, and he is happy, until he starts to miss being special.
  • I Just Want to Be Special: In "Nega-Globby", he is initially happy to be normal again, but soon finds it boring, because his life as a mutant was exciting and he misses being a valued member of a supervillain team and, later, an ally of the heroes. Then, Nega-Globby shows up and threatens his city and friends, so he steals Honey's purse again and transforms back into Globby.
  • Imagination-Based Superpower: His goo takes any form and shape he wishes.
  • Iron Butt Monkey: Thanks to his gelatinous form that can take any shape and detach and reattach itself, the numerous Amusing Injuries Globby goes through never have full-term consequences on him.
  • Jerkass Ball: Probably his biggest jerk moment was telling Hiro he was useless without his friends. Though it was part of Obake's plan to test Hiro.
  • 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.
  • Laughably Evil: Even as a Not-So-Harmless Villain, he is an adorkable, klutzy Butt-Monkey.
  • Light Is Good: His glob form is a light purple, and he makes a Heel–Face Turn later on.
  • Meaningful Name:
    • There's the obvious fact that he's made out of glob, hence being named "Globby".
    • His human name, "Dibs", means "a small amount of money". Dibs was your average purse-stealing thief before becoming the supervillain Globby.
  • Nice Guy: Was not mean to begin with, and after a Heel–Face Turn and Character Development, he becomes a full-on nice guy by Season 2.
  • No Sense of Personal Space: He doesn't seem to be aware that the concept of personal space even exists, which annoys Momakase in "Countdown To Catastrophe".
    Momakase: Your breath smells like garbage.
  • Not-So-Harmless Villain: Once he realizes how his shapeshifting powers work, he actually gives Big Hero 6 quite a hard time.
  • Only Known by Their Nickname: Other than his alias "Globby", his human name is "Dibs", which is most likely a nickname.
  • Painful Transformation: The chemicals of Honey's purse along with the neurotransmitter turn his whole body into glob, INCLUDING HIS BONES. Dibs' screams in his first transformation just shows it can't be pleasant. Globby even lampshades it when turns back into Globby for the second time:
    Dibs: Oh, I forgot how much this part hurt! [groans loudly in pain]
  • Pet the Dog: He give Hiro a chocolate bar before he runs off with the stolen painting.
  • Platonic Life-Partners: He develops a close bond with Honey Lemon.
  • 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.
  • Reality Ensues: In "Nega-Globby", he tries to find a normal job. Too bad, people are not eager to hire a Blob Monster, because he scares the customers and sheds his goo everywhere.
  • 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.
  • Seventh Ranger: As of Season 2 and post-Heel–Face Turn, Globby becomes a strong ally to Big Hero 6.
  • Shadow Discretion Shot: His first transformation from Dibs to Globby is shown dramatically from a shadow on the wall. It's justified since the chemicals, turns his whole body flesh, muscles, bones included into glob.
  • 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.
  • Villainous Rescue: Although he did kidnap Krei, he saves him from falling to his death when he accidentally causes him to fall of a skyscraper.
    Krei: This is a little awkward. Thanks, I guess...
  • 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.

    Felony Carl 

"Felony" Carl
Voiced by: Diedrich Bader
Appearances: The Series (debut: "Big Roommates 2")

A former felon who works as a bouncer to various places. He lives in GoGo's and Honey's neighborhood and is a friend of Dibs/Globby.

  • Ambiguously Brown: He's olive-tanned.
  • Badasses Wear Bandanas: A large thug that wears a red bandana.
  • Big Ol' Unibrow: A thick monobrow is a prominent feature of his Face of a Thug.
  • Bouncer: His job, as seen in "Food Fight" and "Mr. Sparkles Loses His Sparkles".
  • Deadpan Snarker: One of his main traits.
    Mr. Sparkles: Don't you know who I am?
    Felony Carl: A guy with an over-inflated sense of self?
  • Face of a Thug: He looks like a tough, scary guy, but is actually a very kind person.
  • Friend to All Living Things: He immediately bonds with a cat and "Something Fluffy" shows him on his motorcycle filled with Mayoi.
  • Gentle Giant: He's huge and scary-looking, but quite friendly.
  • Guttural Growler: He speaks with a low, deep voice, but he's quite soft-spoken.
  • Hidden Depths:
    • In "Aunt Cass Goes Out", he describes himself on his dating profile as a "hopeless romantic".
    • He appears to be quite a Cuddle Bug. Who would've known by simply looking at him.
  • Icy Blue Eyes: Subverted. Felony Carl looks rather intimidating in appearance, but once you get to know him, he's actually a kind, friendly person.
  • Kick the Son of a Bitch: Calls Mr. Sparkles a nobody after he loses his popularity to Mochi. Considering how much of an obnoxious self-centered jerk Mr. Sparkles is, he deserved it.
  • Kindhearted Cat Lover: He's quite affectionate to cats, and immediately bonds with one that was clawing at Globby's face moments earlier. "The Globby Within" shows that he's adopted it.
  • Meaningful Name: "Carl" means "strong man", which definitely fits Felony Carl.
  • Morality Pet: Is the one reason Globby did his Heel–Face Turn. Felony Carl is his Only Friend, or his "whole list" as he says.
  • Mr. Exposition: He knows a lot about the criminal underworld, as "The Fate of the Roommates" shows.
  • Nice Guy: Oddly enough is probably the kindest person on the show outside of Honey Lemon.
  • Noodle Incident: He did something that made him go from being called "Misdemeanor Carl" to "Felony Carl".
  • Not So Above It All: He fell just as hard as everyone else for the Mayoi, and he's shown to have adopted at least a dozen who all hang out on his motorcycle.
  • Only Friend: Dibs sees him as this, though Felony Carl just seems to tolerate him at best. However, by Season 2 they seem to have become genuine ones, with Carl even acting as a sort of emotional support for Dibs.
  • Only Known by Their Nickname: Is known by everyone as "Felony Carl" rather than simply "Carl". Carl implies it's his mother who started the nickname. Back in his youth, he was "Misdemeanor Carl".
  • Real Men Wear Pink: Asks Honey Lemon to make his motorcycle hot pink with glitter.
    Felony Carl: Love the glitter. It showcases how comfortable I am with my masculinity.
  • Reformed Criminal: Possibly. He seems aware of the crime happening throughout the city, even the underground type, but nonetheless has never committed any crime on-screen. It was also mentioned on his dating profile that he got out of jail recently.
  • Unfazed Everyman: When he meets Globby for coffee after his transformation, Felony Carl isn't bothered in the slightest that he's talking to a humanoid goo man. He isn't even bothered by Mr Sparkles's over-the-top ego-derived antics in a later episode.

    Megan Cruz 

Megan Cruz
"Hiro, we're going to have to change this all work, no play lifestyle. It's not healthy."

Voiced by: Isabella Gómez
Appearances: The Series (debut: "Something's Fishy")

The 14 year-old daughter of an old friend of Aunt Cass. She becomes Hiro's friend after the latter introduces them to each other.

  • Adorkable: She's very excited about being a journalist and trying to discover Big Hero 6's real identities. She also calls herself "Super Sleuth Megan Cruz".
  • Camera Fiend: Comes with being in photography club and her school's journal.
  • Daddy's Girl: Seems to have a good, loving relationship with her father, even if he's embarassing at times.
  • Deadpan Snarker: She has a sarcastic side, though it's more playful than derisive.
    Megan: [after seeing Hiro dance] You're not a genius at dancing.
  • Decomposite Character: Seems to be based of Marys Iosama from the comics, who, like Megan, is a nice, friendly and sassy girl Hiro's age who ends up befriending him. The Teen Genius part of Marys' character has been given to Karmi.
  • Determinator: As Hiro discovers, Megan will stop at nothing to discover Big Hero 6's true identities.
  • The Everyman: She's a normal high school student, compared to Hiro and most of the cast, who are technological geniuses.
  • Foil:
    • To Karmi and Trina. All of them are female acquaintances to Hiro, are around his age, and have had Ship Tease with him. Karmi is his rival at SFIT and despises him (except for his alter ego) and Trina is what Hiro would've been like if he had stayed in bot-fighting and also turns out to be a villain and Obake's "daughter". As for Megan, she's an ordinary girl who has no problem getting along with him and the two hit it off pretty well and become friends. Unlike Karmi, she is a threat to Hiro's superhero life rather than a source of help to it, but unlike Trina, the threat is of a good-natured variety rather than a villainous one.
    • To Hiro. Megan is a normal 14 year old kid with interests, attends high school and loves to have fun. Hiro never got to live a normal life due to being a Child Prodigy growing up and being a superhero in the present day. He also doesn't do activities outside of school, his internship at Krei Tech and superhero missions, making him wonder if he misses out on being a normal 14 year old kid.
  • Genki Girl: She's always happy and has a child-like glee when it comes to photography.
  • Girl Next Door: A normal Nice Girl who's new in town and becomes the protagonist's friend while having some Ship Tease moments with him.
  • Hair Decorations: Wears a green clip in her hair with her everyday clothing. In the school dance from "Something's Fishy", she wears a blue hairclip to match with her dress.
  • Intrepid Reporter: She works for a school newspaper and is dead set on finding out Big Hero 6's real identities.
  • Latina Is Brown: She's voiced by Isabella Gomez and has the Hispanic surname of Cruz.
  • Manic Pixie Dream Girl: Downplayed. Though she has a few Ship Tease moments with Hiro, Megan's primary role is one of a new friend of Hiro's age that makes him see the world through the eyes of a normal 14 year old kid and have fun like kids their age normally do.
  • Missing Mom: No clues of her mother's whereabouts. Her dad is apparently single, as he attempts to romantically pursue Aunt Cass.
  • Morality Pet: Chief Cruz is at his most sympathetic when it comes to his daughter.
  • Nice Girl: Is overall pretty friendly and sociable, especially when compared to Hiro's other love interests.
  • No Sense of Personal Space: She gets really up close to Big Hero 6 and pressures them into giving their real identities.
  • Omniglot: Implied. One of her elective in high school is foreign languages.
  • Plucky Girl: Determined to find Big Hero 6's true identities for her school's journal.
  • Protectorate: To her father, BIG TIME.
  • School Clubs Are Serious Business: Megan is in photography club, foreign language, and also works for the school journal, and she takes her work VERY seriously.
  • Ship Tease: To some extent with Hiro. The two are only friends, though everyone else around them (especially Aunt Cass) thinks there's something going on between the two.
  • Stalker Without a Crush: She has a conspiracy wall about Big Hero 6 and stalks them to find out their secret identities.
  • String Theory: Megan has a whole conspiracy wall of Big Hero 6's whereabouts with red thread in her bedroom.
  • Teens Are Short: Is a teenage girl about the same height as Hiro.
  • Tomboyish Ponytail: Styles her hair in a short high ponytail.
  • True Blue Femininity: Wears a blue dress at the school dance she brings Hiro to in "Something's Fishy".

    Roddy Blair 

Roderick "Roddy" Blair
Voiced by: John DiMaggio
Appearances: The Series (debut: "Hardlight")

An architect that built Boss Awesome's lair and is hired to build Big Hero 6's lair.

  • Big Fun: He's bulky and a nice guy, but it's downplayed as his impatience towards Fred doesn't play this trope straight.
  • Brought to You by the Letter "S": He wears a cap with the first letter of his name on it.
  • The Engineer: He specializes in building superhero lairs, and is called by Fred to build Big Hero 6's secret base.
  • Fiery Redhead: Averted. He's more dismissive than fiery.
  • Gadgeteer Genius: He builds superhero lairs, which includes a lot of electronic devices.
  • Gentle Giant: Roddy is a tall and quite friendly guy (well, when he feels like it).
  • Hates Being Touched: He's not a hugger. He gives Fred exactly three seconds to stop his hug.
  • Jerk with a Heart of Gold: He's a bit insensitive towards Fred at times, but he's quite a nice guy, as he helps Hiro find a solution to defeat Hardlight and doesn't despises Fred himself.
  • Mentor Archetype: Of a sort. He seems to like Hiro, who he tells to play his own game and do what he's best at in order to defeat Hardlight.
  • Nice Hat: Has a cap with a red "R" on it.
  • Old Friend: Of Boss Awesome.
  • Secret Secret-Keeper: He knew Fred was in Big Hero 6 despite never having meeting him before "Hardlight". Justified; since he knew Boss Awesome personally, of course he knows Fred's real identity as a member of Big Hero 6.

How well does it match the trope?
