List of Disney's ''Big Hero 6'' characters

Hiro Hamada

Hiro Hamada 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 San Fransokyo Institute of Technology and put his brain to work. However, tragedy struck when Tadashi perished in a fire. From this, Hiro decided to use his smarts to form a team with his friends and lead Big Hero 6.

Hiro is loosely based on Hiro Takachiho and is voiced by Ryan Potter in all forms of media.^[2]

Baymax

Baymax is an inflatable health care robot that was created by Tadashi Hamada. Baymax's only function has been to help people not just physically, but mentally and emotionally as well. After Tadashi's death, Baymax felt that his purpose is now to help Tadashi's younger brother Hiro. Equipped with "10,000 different medical procedures", various forms of martial arts, but a loose grasp of common thinking, Baymax does all he can to rescue people in more ways then one.

Baymax is loosely based on the character of the same name and is voiced by Scott Adsit in all forms of media.^[3]

Honey Lemon

Honey Lemon is a chemist who enjoys what she does. While somewhat maniacal and eccentric, she deeply cares for her friends and does everything she can to bring optimism to the group. She does not necessarily think violence is the answer to everything, but she will throw herself into the fight when needed.

Honey Lemon is loosely based on the character of the same name and is voiced by Genesis Rodriguez in all forms of media.^[4]

Go Go Tomago

Go Go Tomago is an adrenaline junkie who prefers working with electromagnets. She does not socialize with people much and comes off as rude and anti-social, but is really a team player. When fighting, she comes off as the most experienced due to her background, but prefers to fight alongside her team.

Go Go is loosely based on GoGo Tomago and is voiced by Jamie Chung in all forms of media.^[5]

Wasabi

Wasabi 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. While he is apparently cowardly, he pulls through for his friends and occasionally shows a flare for the heroic life much to everyone's and his own shock.

Wasabi is loosely based on Wasabi-No-Ginger and is voiced by Damon Wayans Jr. in the film and Khary Payton in the television series.^[6]

Fred

Frederick "Fred" Frederickson IV 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.

Fred is loosely based on the character of the same name and is voiced by T.J. Miller in the film and Brooks Wheelan in the television series.^[7]

Tadashi Hamada

Tadashi Hamada was the older brother to Hiro and, just like him, displayed a knack for understanding and building various forms of technology. He built Baymax for the sole purpose of helping people, but was unable to see this to fruition due to his early death. His death sets in motion a series of events that would lead Hiro to forming the Big Hero 6.

Tadashi is voiced by Daniel Henney in all forms of media.^[8]

Aunt Cass

Aunt Cass is Hiro and Tadashi's aunt who was granted custody of them after the death of her sister and brother-in-law. Cass continued to care and love them as if they were her own children though like any other parent she would feel concern and anger whenever they got into any trouble. She bailed them out of jail after an incident involving bot fighting and regretted the fact that she never picked up a book on parenting. She is present when Hiro presents his microbots at the SFIT showcase and expressed joy at seeing him succeed. Cass planned on an after party for her nephews and friends, but Tadashi is killed in a fire, devastating her and Hiro. Weeks later, Cass tries to cheer Hiro up and get him out of house, leading into a series of events involving Hiro, Baymax and his friends becoming Big Hero 6, all while Cass remains blissfully unaware. Hiro eventually begins attending SFIT much to Cass' happiness and support.

The television series expands on her character, depicting her as not only being unaware of her nephew's heroics, but displaying some eccentricities when it comes to cooking and food.^[10] This is further shown in the episode "Food Fight" where she not only is shown mastering many uncommon dishes with a variety of unfamiliar ingredients, but she is shown to love doing so to challenge herself.^[11] Cass also displays a ditsy personality that sometimes hinges on ignorance. Though once she does become aware she takes her situation seriously. She also has never dated or gotten married prior to the events of "Aunt Cass Goes Out" and while she did find Alistair Krei interesting and romantic, she ultimately saw his flaws enough for her to dump him.^[12]

Alistair Krei

Alistair Krei is the self-made CEO of Krei Tech. Considered an influential man, Krei is always searching for the next best thing and found it in Hiro Hamada's microbots at SFIT. He is heavily impressed with Hiro's microbot project and ask that his tech be bought by his company, but he is turned down after a stern talking to by Professor Robert Callaghan with whom he had a rough past with. It is soon revealed that Krei had helped develop a special teleportation device for the government of which Callaghan's daughter, Abigail, was a test pilot to. The test went wrong and Abigail was thought lost somewhere in the unknown and since then Krei has been blamed. Despite this, he has continued in his illustrious career as if nothing happened revealing a morally dubious side. Krei is soon attacked by a vengeful Callaghan, but is rescued by the Hiro and his friends as the Big Hero 6. After Callaghan's defeat and Abigail's rescue, Krei went back to business now somewhat more aware of his actions.

The series continues to display his morally ambiguous personality. While not evil, he is manipulative and seems to hold absolutely no concern for anything. He outright decides to copy Hiro's microbot transmitter, something his assistant outright confirms^[14] and rushes production on a defense drone that he failed to run diagnostic checks on. When he realizes this, he demands that the Big Hero 6 fix the problem or else he will blow their identities. He presents a charming facade when he meets Hiro's Aunt Cass which she falls for, but after revealing his true self, even she found him despicable.^[12] 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.^[15]

Yokai

Yokai (Professor Robert Callaghan) is a supervillain who was once a kind and respectable Professor and dean at SFIT. Coming from a military background,^[17] Professor Robert Callaghan is a pioneer in developing many cutting edge tech inventions including the Callaghan-Catmull Spline. He had a daughter that he loved dearly named Abigail who grew up to become a test pilot for Krei Tech. When a teleportation accident left her test pod lost in an abyss, Callaghan angrily blamed Krei and swore revenge. He taught many students at SFIT and met Hiro Hamada the younger brother of his star student Tadashi. Callaghan was impressed with Hiro's invention: Microbots that are controlled by a head transmitter. Seeing this as an opportunity to get back at Krei, Callaghan started a fire and stole Hiro's microbots, but unintentionally killed Tadashi. Nevertheless, he continued his quest under the name Yokai and stole many parts to recreate the teleportation machine in an effort to destroy Krei Tech's new building and Krei himself. He is thwarted by the arrival of the Big Hero 6 who manage to retrieve Abigail from the portal. When Callaghan is carted away by police, he sees his still living daughter being tended to and could only put his head down in shame for the crimes he had and was about to commit.

Callaghan returns in the episode "Mini-Max" where it is shown that he is being kept in a high-level security prison. He reveals that he has worked with Professor Granville in the past as she was one of the best teachers working at SFIT and that she had initially resigned due to an accident. While Callaghan is remorseful of his actions, especially towards causing the death of Tadashi, Hiro still refuses to forgive him.^[18]

Mr. Yama

Mr. Yama is a notorious Japanese gangster who runs much of the underground illegal activities in San Fransokyo which includes bot fighting. He owns his own bot dubbed "Little Yama" which he prides himself on using due to its violent attacks. However, he is outsmarted by Hiro Hamada whose simpler bot managed to overpower and destroy his own. Not wanting to be outdone, Yama asked his men to "teach [Hiro] a lesson". He gives chase when Hiro is rescued by Tadashi, but after the whole commotion, Yama, Hiro, Tadashi as well as everyone participating in the illegal bot fighting are arrested.

Sometime later, he got out of prison and has gone back to doing illegal work. In the premiere episode of Big Hero 6: The Series, "Baymax Returns", Yama has started to work for the mysterious Obake of whom he himself is afraid of. The series further shows that despite his large overweight appearance, he does display some technical knowhow as he was able to replicate and mass produce Baymax's skeleton after having him for a limited amount of time. He is nevertheless defeated by Hiro once again along with his friends.^[10] Yama is also shown to not be very good at working with or controlling others such as in "Food Fight" he was easily outsmarted by Momakase who paralyzed and stole back a device she initially stole for him.^[11] In "Small Hiro One", Yama is also revealed to have a giant variant of Little Yama called "Mega Yama" which he had attempted to upgrade. In that same episode, he is shown to be unaware that Hiro and his Big Hero 6 alter ego are one and the same.^[20] Despite his criminal occupation, Yama takes samba classes on the side.^[21]

Professor Granville

Professor Grace Granville is the new dean of SFIT after Professor Callaghan is arrested. Granville came to replacing him the day Hiro started his first day at school. Despite finding Hiro unfocused and selfish, she saw great potential in him due to being related to Tadashi whom she found to be an exceptional student. She continued to question Hiro's motivations and is shown to dislike direct physical contact with people. Later on, she realizes how important it was for Hiro to remember his brother and opted to give him his lab in the hopes that it will keep him focused.^[10] Granville shows concern for all if not most of her students including the envious Karmi. Granville gave off the impression that Hiro needed to socialize more and paired her up with Karmi, seemingly unaware of the fact that she disliked Hiro. However, it becomes apparent that Granville intended for Karmi to take a lesson from their brief gathering implying that she is well aware of her moody personality.^[22] When Hiro attempted to give up on a project, Granville refused for him to quit, showing that despite her prior perceptions of him, she still considers him a genius.^[23] Granville has shown a comically eccentric side as well. In "Rivalry Weak", she is shown to take the pranks between SFIT and San Fransokyo Art Institute seriously by forcing Wasabi and Fred to act as guards to the cafe, which is the source of SFAI's pranking.^[24]

It is revealed in "Small Hiro One" that she had taught at SFIT twenty years prior, something that she had apparently never brought up to Hiro. Her old students included Trevor Trengrove, Wendy Wower and Obake.^[20] In "Mini-Max", Granville reveals that one of her students (unnamed, but clearly Obake) was one of the greatest geniuses at SFIT to the point that she allowed him to take whatever risks he wanted. Unfortunately, this resulted in Obake injuring himself in an accident with Granville taking the fall and causing her to resign. She returned years later, but with the intent of keeping her students under control as she feels that "students need limits, even geniuses" and presumably fears that if not accounted for, Hiro could end up the same way. She is later comforted by the fact that Hiro is genuinely a good person.^[18] Evidently, it is revealed that she is well aware of Hiro and his friends' efforts as Big Hero 6.^[25]

Obake

Obake (Bob Aken) is a mysterious villain and former SFIT student^[26] with a strange fascination for the Big Hero 6. His obsession for the team has been apparent since before they officially decided on being superheroes. He has control over many other villains including Mr. Yama.^[10] Through Yama, he also worked with Momakase.^[11] He tasked Globby with stealing a painting for him, which contained blueprints behind its frame, and expressed interest at his super powers which he stated was useful.^[23] Obake directly meets with the Mad Jacks for a mission, however he intended for them to lose to the Big Hero 6 and was successful in this case. Through his planning a special chip was acquired by Krei who used it to look for special information. While there was not anything on it, Obake's plan was for it to be used to trace information from Krei's personal files, ultimately discovering the identity of Hiro Hamada.^[27] He later learns the identities of the rest of the team after kidnapping and reprogramming Noodle Burger Boy so as to use its prediction algorithm.^[15] He soon uses some of his information to feed self-doubt into Hiro forcing him to make future irrational decisions^[28] and to manifest the fears of the rest of the team.^[29] He finally reveals himself to the Big Hero 6 in "Rivalry Weak" after he steals a journal belonging to famed artist and secret scientist Lenore Shimamoto.^[24] In "Steamer's Revenge", he was willing to aid the Big Hero 6 as long as it helped further his goals.^[30]

In the episode "Mini-Max", it is implied that Obake has a major vendetta against Granville, implied to be due to the accident that turned him into what he is in the present.^[18] In "Countdown to Catastrophe", it is revealed that he blames Granville for holding him back. In his youth, Obake attempted to create a energy amplifier, but was caught in an accident that severely affected his temporoparietal junction (the part of the brain that tells right from wrong). Feeling that his experiment could work, he opted to create a machine using Shimamoto's notes to create a powerful star that could wipe out San Fransokyo so that he can recreate is in his own image and bring Hiro on as his apprentice. He is defeated when the Big Hero 6 manage to circumvent the disaster and resigns himself to his slowly crumbling lair. What became of him is not revealed.^[25]

Globby

Globby (Dibs) is a minor thief who was transformed into a super powered villain. Dibs was lived in the more harsher parts of San Fransokyo where he partook in his favorite pastime: taking part in petty crime by stealing purses. He was a terrible at his "job" as he always found himself losing whatever it was he tried to steal. He was finally successful in stealing Honey Lemon's chem-purse, thinking it was a regular purse, and hid in a warehouse belonging to Alistair Krei. Krei had created a neuro-transmitter, based on Hiro Hamada's design, and realizing it was worth something, decided to steal it. However, Dibs tried to flee with the transmitter and accidentally destroyed the chem-purse, mixing together and coating him with a gooey substance that turned him into a monster. Taking the name Globby, after hearing him being called that by Fred, he had decided to become a career supervillain. He is not entirely evil though as he does not like killing people, rather he thinks it is better to humiliate others.^[14] In "Failure Mode", Globby learns that he can alter his own matter, turning into metal, wood, acid, chocolate etc., and actually defeats the Big Hero 6. He once again shows a softer side by giving Hiro chocolate after defeating him.^[23] In "Kentucky Kaiju", he seems to have become a full time lackey to Obake.^[28] He eventually sees the error of his ways once he realizes that Obake is crazy and not "fun crazy" and helps the Big Hero 6 bring down his plan. He apparently considers Felony Carl his only true friend.^[25]

Karmi

Karmi is an intellectually gifted biology student at SFIT and Hiro's academic rival. Karmi was initially the youngest student attending SFIT, a fact that she was inherently proud of. She was considered anti-social by many and did not have any friends, considering the germs and microbes that she studied as her friends and treated almost as pets. When Hiro Hamada began seriously attending SFIT, Karmi felt threatened and showed an egotistical, cynical and boastful side. She cared very little for Hiro and hated working with a student that she felt "stole her thing" as the youngest student at SFIT. Ironically, Karmi has a huge crush on Hiro's superhero alter ego of which she was completely unaware was the same person. She is also under the assumption that Hiro has a crush on her of which she mocks him for.^[22] She prefers seeing Hiro fail to the point that she will record and upload his failures online, though it has been proven that he is smarter than her to a certain degree.^[23] Despite this, her invention gets funded by billionaire Liv Amara.^[31] She can be purposefully manipulative to those around her such as in "Kentucky Kaiju" when she convinced other students that Hiro's accidental mishaps were done on purpose.^[28]

Karmi has shown some concern for the health of others and criticized Hiro for not considering his own health and those around him when he was sick.^[27] She later gained his sympathy when famed scientist Trevor Trengrove kicked her out of his lecture and thanked Hiro for understanding, though they were both mutually disgusted by this afterwards.^[20] Karmi also writes fan fiction about herself and the Big Hero 6 with Hiro (whom she calls "Captain Cutie") depicted as her boyfriend. She incorporates her own scientific thoughts into her stories as they end up inspiring the heroes to use their powers in new and interesting ways.^[32]

Richardson Mole

Richardson Mole is a fanboy, comic book nerd and Fred's arch-nemesis. Self-described as "San Fransokyo's most eligible eleven year old", Mole is a short, overweight, rich snob who is the antithesis to Fred. He owns his own comic book store and does everything he can to outsmart and humiliate his much older rival. He fancies himself as a ladies' man and pursues Go Go whom he affectionately calls "dream girl". However, the only thing the two seem to have in common is their mutual feeling of annoyance from Fred, though in Go Go's case it is only mild bemusement while Mole outright dislikes him. He owns a whole arcade dedicated to his hatred to Fred with a Whac-A-Mole variant being his favorite. Fred only gets favors from him as a last resort which Mole is happy to oblige to simply to show his superior collection compared to Fred's.^[22] His mother Binky Mole appears to not like her son's hobby, which does not seem to bother him, but he does hate it when people comment on his hygiene which is apparently terrible.^[12] He is further shown to be manipulative and even downright sinister as shown in "Big Hero 7". When he found out about the Big Hero 6's identities, he did not feel concern for the potential harm it could bring to others. By the end of the episode, a major static shock to him by High Voltage's orb caused him to forget their identities.^[33]

Felony Carl

Felony Carl is a former criminal in San Fransokyo. Carl was given his nickname by his own mother, which he does not seem to mind as it is technically an accurate name. He gave up a life of crime, but continued to live in the rougher neighborhoods in San Fransokyo. He is shown to be positive about his own masculinity, as he admitted that he liked having his motorcycle colored glitter-pink. Carl is somewhat friends with Dibs, though he looked down on his attempts to be a criminal and told him to give up. After Dibs transformed into Globby, he still continued to criticize him though the two still seemed to be okay with him.^[14] Despite his huge and intimidating appearance, he is shown to be a very insightful person and very good at analyzing certain things and people. He nevertheless manages to find work as a bouncer for various places including the underground Food Fight competition^[11] and for various clubs throughout the San Fransokyo night life.^[34] Carl is also a self-described "hopeless romantic" and is shown trying to pursue a love life.^[12]
