The Hamada family
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 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.
- 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 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.
- 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.
- 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 Hiro one when they're both in jail.
- 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.
- 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 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.
- 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.
- 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?

- Red Oni, Blue Oni: The mature, responsible Blue Oni to Hiro's brazen, impulsive Red Oni.

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

- 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.

- 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.
- Dub Name Change: In the two french versions, Aunt Cass' name is changed to "Tante Cassie" (Aunt Cassie) since "Cass" sounds too anglophone.

- 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.

- 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...

- 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.
- 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:
Aunt Cass: [grimaces after tasting her acai-salami bowl] Ugh! Can't believe Hiro likes this!
- "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.
- 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.

- Beware the Nice Ones: Mochi is the sweetest cat... until you try to attack Hiro and Baymax.

- 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!".

- Death Glare: Gives one to Hiro after he threw him up the stairs.

- 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.
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.
- 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.
- 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.
- 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.

- Boots of Toughness: For extra awesomeness, Mr. Frederickson fights Supersonic Sue and Baron Von Steamer wearing cowboy boots.

- 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.
- 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.

- 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.
- Parental Abandonment: 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.

- Would Hit a Girl: He showcases a wrestling move on Supersonic Sue during their fight. Though she is a supervillain trying to defeat him...

Appearances: Big Hero 6 (picture only) | The Series (debut: "Fred's Bro-Tillion")
Fred's mother and Mr. Frederickson/Boss' Awesome's wife.
- 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.

- 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.
- Drunk on Milk: As seen in "Muira-Horror!", Mini-Max has the same drunk behavior as Baymax when on low-battery.
- 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.
- Light Is Good: Just like Baymax, Mini-Max is all white and an ally.
- No Indoor Voice: Due to his Large Ham personality, he is constantly shouting. And if you think he can't scream louder, he can.
- 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: Mini-Max is always excessively cheerful, even as he tells Fred that he have blown his mind.
- 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.
- 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.
- 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.
Six remote-controlled robots created by Hiro to deliver the team's suit.
- 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 accidentally called it "Baymax". 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. However, in "Countdown To Catastrophe", Hiro uses his Skymax to get to the highlight and deactive his energy amplifier.
- 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.
San Fransokyo Institute of Technology Faculty and Other Students
Professor Robert Callaghan
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.
- 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.
- Evil All Along: He was already planning his revenge on Krei when we were introduced to his character.
- 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 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.
- 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.
- 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.
- 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 villaint.
- 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.
Professor Grace Granville
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!
- Affectionate Nickname: Karmi calls her "Professor G". Surprisingly, she doesn't mind it.
- Alliterative Name: Grace Granville.
- 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.
- 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.
- 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.
- 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—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.
- However, played straight with Liv Amara. She has no idea who she truly is and sees her as an old 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 as this 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:
Professor Granville: I LOOKED DOWN! I LOOKED DOOOOWN!
- "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.
- 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 frightened.
- 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 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".
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).
- 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.
- Ascended Fangirl:
- 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.
- 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.
- Belligerent Sexual Tension: In some way, with Hiro (when he's not in superhero gear).
- 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.
- 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, 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.
- Companion Cube: Karmi talks to her viruses, puts cute stickers on their petri dishes and considers them her friends.
- Damsel in Distress: Just like Marys Iosama before her.
- In "Issue 188", she almost gets crushed by a falling lamppost. Hiro saves her just in time.
- Momakase kidnaps her in "Fan-Friction" to lure Hiro and the team into a trap.
- Though by "Big Problem" and "Prey Date", Karmi seems to gradually grow out of this trope by being thrown in the middle of the action.
- 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.
- 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' 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 Granvilles 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.
- Fangirl: To Big Hero 6, especially "Captain Cutie". Also of Liv Amara.
- Foil: Her interest in germs and pathogens — which can hurt people — contrasts with Hiro, Tadashi, and Baymax's focus on healthcare and rescuing people.
- 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 really 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 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: She appears to be one of these around Granville when Hiro is assigned to help her socialize; subverted when Granville leaves the room and she's revealed to be a Stepford Smiler, warning Hiro to not interfere with her workspace, since she used to be the youngest student at SFIT until Hiro enrolled.
- Double subverted come "Fan Friction" and "Big Problem", where we see that Karmi actually can be a genuine Genki Girl when excited about something she has a passion for.
- 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.
- Hates My Secret Identity: Karmi's in love with superhero Hiro, but really despises Hiro Hamada the student.
- 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.
- 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:
Baymax: Oh, no.
- In "Prey Date", after Orso Knox's containment unit changes from "secured" to "disabled":
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.
Hiro: So, Karmi, did your serum work?
- After the team has brought Orso Knox back:
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.
- 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.
- 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 waist.
- Loves My Alter Ego: She seemingly has no idea that Hiro is Big Hero 6's "Captain Cutie", who she is in love with.
- 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.
- Nice Girl: What she initially comes off as...and then she tells Hiro to back off.
- 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.
- 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.
- Proper Tights with a Skirt: Wears an orange skirt over black leggings as her everyday outfit.
- 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 (though he starts to play more in the rivalry in 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.
- 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.
- 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.
- 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.
- 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.
- Wrong Genre Savvy: She thinks Hiro is crushing on her solely because he's being polite and wants them to work on their project.
The Cruz Family
The 14 year-old daughter of an old friend of Aunt Cass. She becomes Hiro's friend after the latter introduces them to eachother.
- Daddy's Girl: Seems to have a good, loving relationship with her father.
- 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.
- The Everyman: She's a normal person, 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.
- She's also 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.
- 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.
- 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.
- Nice Girl: Is overall pretty friendly and socialable, especially when compared to Hiro's other love interests.
- Omniglot: Implied. One of her elective in high school is foreign languages.
- Ship Tease: With Hiro. When Aunt Cass introduces the two to each other, they seem to hit it off pretty well.
- 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".

- Amazingly Embarrassing Parents: According to Megan, Chief Cruz has his moments.
- Da Chief: San Fransokyo Police Department's new chief of police.
- Good Parents: While being a no-nonsense cop that hates superheroes, he's a good father to Megan.
- Hidden Depths: Despite being stern and hating superheroes, Megan states that her father can be embarassing when it comes to her. For an example, she tells Hiro he took a ton of pictures of her in her dress the same way as Aunt Cass did for the two of them before letting her go.
- Jerk with a Heart of Gold: Clearly loves his daughter, but nonetheless has a completely unwarranted grudge against Big Hero 6.
- Latino Is Brown: Voiced by Nestor Carbonell and has the Hispanic surname of Cruz.
- Likes Clark Kent, Hates Superman: Has no issue whatsoever with Hiro, but sees Big Hero 6 as nothing more than vigilantes who aren't needed to protect his city.
- Nice Hat: Wears a police hat.
- No Name Given: So far, he's only known and credited as "Chief Cruz".
- Old Friend: Of Aunt Cass.
- Overprotective Dad: He once had the entire police force looking for his daughter because she was only 7 minutes late home from photography club.
- Papa Wolf: Implied to be extremely protective of Megan. Look above.
- Police are Useless: Regardless of his claims that the police can handle the threats facing the city, it has only been proven time and time again that, due to their lack of superpowers, they're utterly useless against actual supervillains. Though he swears to correct that now that he's the new chief of the Police Department.

A kids' TV Show Host and a former robotics student at SFIT.

- Alliterative Name: Wendy Wower.
- Ambiguously Brown: Her skin tone is a tan olive tone, but we have no mention of her ethnicity.
- Anime Hair: Either Wendy uses a lot of hairspray, either her two green pigtails can defy gravity.
- Brainy Brunette: Is a natural brunette and was a robotics major at SFIT in her youth. She was Trevor's lab partner and he stole the robotics thesis that made him famous from her.
- Cloud Cuckoo Lander: Perhaps her TV character has grown into her actual personality, but Wendy has a few weird quips.
- Excited Kids' Show Host: Is the host of her own show "Wendy Wower Science Hour", and she teaches science to her kid audience with an energetic, jovial attitude.

- Labcoat of Science and Medicine: Her character wears a bright orange lab coat. She later gains the title of doctor and keeps it.
- 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 Shoes: She has bright pink shoes with purple highlights along with yellow lightnings on the sides, similarly to the Olympian God Hermes.
- 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.

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.
- 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.

- HeelFace 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.

- Badasses Wear Bandanas: A large thug that wears a red bandana.
- Bouncer: His job, as seen in "Food Fight" and "Mr. Sparkles Loses His Sparkles".

- Face of a Thug: He looks like a tough, scary guy, but is actually a very kind person.
- Gentle Giant: He's huge and scary-looking, but quite friendly.
- Hidden Depths: In "Aunt Cass Goes Out", he describes himself on his dating profile as a "hopeless romantic".
- His Name Really Is "Barkeep": It's implied that "Felony" is part of his actual name. When Honey Lemon tells him to just go by "Carl", he replies "Talk to my mom". Though in Season 2, Globby states he knew Felony Carl back when he was known as "Misdemeanor Carl".
- 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.
- Kind Hearted Cat Lover: He's quite affectionate to cats, and immediately bonds with one that was clawing at Globby's face moments earlier.
- Morality Pet: Is the one reason Globby did his HeelFace Turn. Felony Carl is his Only Friend, or his "whole list" as he says.
- 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".
- 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", with no indication if "Felony" is part of the nickname or actually his first name.
- 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.
- 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.
