List of Disney's Big Hero 6 characters
The following is a list of fictional characters from Walt Disney Animation Studios 2014 feature film adaptation of Big Hero 6, as well as its follow-up television shows Big Hero 6: The Series and Baymax! and its subsequent comic book adaptation through IDW Publishing, based on characters created by Steven T. Seagle and Duncan Rouleau and published by Marvel Comics.
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.
Film introductions
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 the 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.
Baymax
Baymax is an inflatable healthcare robot who 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 was now to help Tadashi's younger brother Hiro. 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.Baymax is loosely based on the character of the same name.
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 Aiko Miyazaki.
Go Go Tomago
Ethel "Go Go" Tomago is a sarcastic adrenaline junkie who prefers working with electromagnets. She is 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 Leiko Tanaka.
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 cowardly, he pulls through for his friends and occasionally shows a flare for the heroic life much to everyone's and his shock.Wasabi is loosely based on Wasabi-No-Ginger.
Fred
Frederick Flamarian "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.
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 form the Big Hero 6.Aunt Cass
Aunt Cass is Hiro and Tadashi's aunt and guardian, who was granted custody of them after the death of her sister and brother-in-law, and owner of the Lucky Cat Café. Cass continued to care and love them as if they were her 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 both 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 expresses joy at seeing him succeed. Cass plans 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 the house, leading to 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 also displaying some eccentricities when it comes to cooking and food. 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. 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 before 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. In season two, she starts dating Chief Diego Cruz, whom she had known since high school. It is later implied that the relationship does not last. In season three, she displays some athletic ability; revealing that she used to play softball when she was in college, and is also very good at singing.
Despite being Hiro's aunt, she acts more like a mother; setting him up to have a date with a girl his age and taking pictures of them when they are going to a dance. She is also shown to be heavily oblivious to major events happening throughout the city, usually due to Hiro and his friends stopping her from seeing anything major happening. At the end of the series, she adopts Noodle Burger Boy and his robot family as her staff. They in turn, affectionately call her "mom", which she admits is weird.
In Baymax!, Cass confides in the titular robot that her attachment to the café is the result of her fearing the loss of her family, as the customers are like family members to her and she is afraid of them leaving her for another establishment. She adds that she "made a promise" to look after her family; implying that she took over the café from Hiro and Tadashi's parents.
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 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. 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. 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 Hiro and his friends who become the Big Hero 6 superhero team. 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 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 whom she falls for, but after revealing his true self, even she finds him despicable. 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. He initially held a minor grudge against Globby for stealing his wallet, but later hires him to be a spokesperson. He accepts Hiro as an intern at his company to compete with Liv Amara whom he has a one-sided rivalry with.
In "Muira-Horror!", Krei finally reveals an honorable, sentimental, and even intuitive side. He reveals that when he was a child he did not have any friends, so when he went to summer camp he would train himself to know the wilds as much as possible, making him surprisingly knowledgeable about nature. He also jumped into action when Go Go was in trouble, something that surprised her and Hiro. 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. He also wanted to have a bunny when he was younger, but his parents forbade him to have any "weak" pets. Despite constantly covering for Big Hero 6, he works with Chief Cruz in trying to capture the team. It was later revealed that he was taken advantage of by Trina. Following the shut down of Sycorax, Krei purchases the building, presumably out of spite.
Yokai
Yokai is a supervillain who was once a kind and respectable Professor and dean at SFIT. Coming from a military background, 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 neuro-transmitter. Seeing this as an opportunity to get back at Krei, Callaghan seemingly 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 to destroy Krei Tech's new building and Krei himself. He is thwarted by the arrival of the Big Hero 6 who manage to stop him and can 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 under solitary confinement in a high-level security prison serving life in prison without parole. 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. Callaghan admits that he is very remorseful of his actions, especially towards causing the death of Tadashi, and that he understands that his apology is not enough for Hiro to forgive him. 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.
