List of Disney's Big Hero 6 characters

While the titular characters originated from Marvel Comics, their characterizations and supporting cast were newly invented by Disney, making their appearance a radical departure from the source material.

[1] Hiro Hamada (voiced by Ryan Potter) is a 14-year-old technology prodigy who initially planned to use his mental brilliance to con others through back alley bot fighting.

Through the advice and swaying of his older brother Tadashi, Hiro decided to join the San Fransokyo Institute of Technology and put his brain to work.

Equipped with "10,000 different medical procedures", and various forms of martial arts, but a loose grasp of common thinking, Baymax does all he can to rescue people in more ways than one.

[6] Wasabi (voiced by Damon Wayans Jr. in the film and Khary Payton in other forms of media) is an expert in laser technology but is an OCD neat freak who prefers to have systems and order in favor of chaos and spontaneity.

[7] Frederick Flamarian "Fred" Frederickson IV (voiced by T.J. Miller in the film and Kingdom Hearts III and Brooks Wheelan in the series) is a total comic book nerd who, despite being the son of a billionaire, spends his time as a sign-flipping school mascot who is a "science enthusiast".

Armed with a kaiju costume dubbed "Fredzilla" and his knowledge of comic book lore, his antics amuse, annoy and aid his friends on the team.

[8] Tadashi Hamada (voiced by Daniel Henney) was the older brother to Hiro and, just like him, displayed a knack for understanding and building various forms of technology.

He is heavily impressed with Hiro's microbot project and asks that his tech be bought by his company, but he is turned down after a stern talking to Professor Robert Callaghan with whom he had a rough past.

[13] While he considers the Big Hero 6 as allies, he prefers that they not visit him often as shown in "Killer App" where after explaining the original plans for Noodle Burger Boy to them, he politely, yet hurriedly, told them to leave.

[28] He initially disliked Christmas due to not being able to celebrate it while at boarding school, but immediately changed his mind after Hiro had Baymax dress up as Santa for him.

Coming from a military background,[35] Professor Robert Callaghan is a pioneer in developing many cutting-edge tech inventions including the Callaghan-Catmull Spline.

[36] He briefly returns in "Hiro the Villain", where Chief Cruz interviews him about Big Hero 6, but he defends them and warns him that his belief of considering them criminals is wrong.

The series further shows that despite his large overweight appearance, he does display some technical know-how as he was able to replicate and mass-produce Baymax's skeleton after having him for a limited amount of time.

[38] "Mini-Max" and "Countdown to Catastrophe" reveal Granville was also a mentor to Bob Aken (Obake) whom she considered enough of a genius to give him free rein in his research.

[16] Obake (Bob Aken) is a mysterious villain and former SFIT student[47] with a strange fascination towards Hiro, extending to the Big Hero 6 since before they officially decided on being superheroes.

This resulted in him suffering injuries caused by an explosion from his attempt of creating an energy amplifier, severely affecting his temporoparietal junction which greatly warped his sense of morality, making him psychotic, and is gradually worsening; despite being given awareness from Baymax, he refuses treatment, finding the condition "liberating".

[36][25] Out of this insanity and his obsessions, Obake masterminded various events in the first season from Globby stealing one of Lenore Shimamoto's paintings for her energy amplifier blueprint to pointlessly learning of Big Hero 6's identities through hacking Krei's personal files and Noodle Burger Boy's prediction algorithm.

Later, Karmi leaves SFIT and San Fransokyo, at the behest of her parents, following the events without saying goodbye to Hiro, but continues to write her fan fiction about Big Hero 6 and herself as Lab Lady.

Self-described as "San Fransokyo's most eligible eleven year old", Mole is a short, selfish, overweight, spoiled, and borderline sociopathic rich snob who is the antithesis to Fred.

But Dibs accidentally destroys the chem-purse while fleeing with the transmitter, the unstable chemical mix turned him into a blob-like humanoid mutant with the neuro-transmitter fused to his skull.

[23] In "Failure Mode", Globby learns that he can use the transmitter to alter his composition into any form of matter he can think off, allowing him to actually defeat Big Hero 6 while becoming the first of Obake's lackeys.

He nevertheless manages to find work as a bouncer for various places including the underground Food Fight competition[12] and for various clubs throughout the San Fransokyo night life.

[25] He completely turns his back on the Noodle Burger franchise and starts working alongside Trina whom he calls "big sis" and becomes openly affectionate to her.

[80] She later turns on Karmi by transforming her into a monster named Phoenomblina[57] and then kidnaps Hiro and Baymax in an attempt to remove the anti-viruses that were actually killing Liv.

Now made to look much older and sporting a hairstyle similar to her creator, Trina, along with Noodle Burger Boy, attempted to use thermonuclear reactors, disguised as garbage trucks, to obliterate San Fransokyo; believing that she would continue her father's legacy.

[78] In "Hiro the Villain", she begins to double down on her researching when she hits a roadblock and quickly discovers that Big Hero 6 have mostly been spotted at places such as Krei Tech and SFIT.

When she learns about Tadashi's death at SFIT and Callaghan's involvement, Megan finally surmises that all Big Hero 6 related events tie back to Hiro.

[85] It was later revealed in "Fred the Fugitive" that his attempt to quell vigilantism was mainly because his father sacrificed his life to a villain to save his son and Boss Awesome arrived too late.

[14] In "Legacies", Cruz finally sees the error of his ways when Megan is kidnapped by Trina and calls upon Big Hero 6 to help find and rescue her.
