Official Disney Bio

Robotics prodigy Hiro Hamada has the mind of a genius—and the heart of a 14 year old: his state-of-the-art battle-bots dominate the underground bot fights held in the dark corners of San Fransokyo. Fortunately, big brother Tadashi redirects Hiro's brilliance, inspiring him to put his brain to the test in a quest to gain admission to the San Fransokyo Institute of Technology. When a tragic event changes everything, Hiro turns to a robot named Baymax, and they form an unbreakable bond—and two-sixths of a band of high-tech heroes on a very important mission.


Hiro Hamada is a young boy with intelligence far beyond his years. Because of this, he can be rather brazen and cocky (Especially when he was seen to be bored during his bot fight with Mr. Yama), but never to the point of being annoying.

He spent much of his time using his technology to win money through illegal bot fight bets (He states that bot-fighting isn't illegal, but betting on it is, though he still did bet on bot-fighting illegally), something he prided himself on, though his older brother Tadashi heavily disapproved. While Tadashi felt that his brother had a greater purpose and should attend college, Hiro believed that he held the knowledge of all that there is to know in the world, or at least all that any school can teach him, showing a strong sense of pride, as well as possible past experiences of school being redundant, unchallenging, and boring for him.

Despite his bold nature, Hiro has a much softer side to him, as he's shown to sometimes be rather shy in front of crowds and during the process of making new friends, as well as socially awkward at times. Even so, he is very compassionate, which, in the beginning, is mostly seen when dealing with his older brother Tadashi who, despite his brotherly nagging, holds a special place in Hiro's heart as the latter's best friend and inspiration. When with Tadashi, Hiro's true colors emerge, showing him to be free-spirited, innocently sassy, warm and ultimately very loving and appreciative. Such aspects wouldn't be seen again until the void left by Tadashi's demise is eventually filled by the lovable Baymax, who cares for Hiro in the same sense, forming a strong companionship.

However, while Hiro has a kind heart, he is a very complex character, and is far from perfect, engaging in some darker behaviors when highly provoked. At certain points during the movie, the boy genius allowed his anger to cloud his better judgement and commit acts normally out of the question. He is similar to Yokai (the villainous mastermind responsible for the death of Tadashi) in this respect, as both experienced the loss of a loved one, thus mutilating their hearts to the point where they sought revenge against the wrongdoers responsible, going as far as conscious murder. However, what separates the two and ultimately classifies Hiro as a hero and Yokai as a villain is the fact that, unlike Yokai, Hiro not only learns the error of his ways, but he makes a serious effort to right the wrongs he caused as quickly as possible. Such revelations are mostly due to the comforting nature of Baymax, the legacy of Tadashi and the support of his closest friends, resulting in a newly-reformed young prodigy who values the lives of all human beings and refuses to carry out acts of justice through the use of violence and murder.

As time would move on following the events of Tadashi's death, Hiro would slowly shape into a heroic, wise and inspirational leader, following in his brother's footsteps. Such traits passed down include Tadashi's philosophy of "looking for a new angle", as well as the devotion to doing whatever is necessary to help others and make the world a better place for all, especially the innocent and deserving. As mentioned above, Hiro would notably organize the Big Hero 6 team, vowing to protect the city of San Fransokyo in order to fulfill Tadashi's lifelong dream of helping others.

Physical Appearance

Hiro is a 14-year old young adolescent boy. According to official sources, he is 5"0" (152 cm) in height.He can often be found in a blue hoodie jacket, a red shirt with a robot on it, long dark beige capri shorts and dark brown trainers with yellow laces. He has fair skin, brown eyes and messy black hair. His eyelashes and eyebrows are somewhat thick and his eyes are a rounded almond shape. When he smiles or opens his mouth, a gap in his teeth can be noticed along with a slight overbite.

Hiro's super-suit is made of primarily indigo with red accents and black armor, with black clothing underneath that covers most of his body up to his knees, along with steel-toe black sneakers. On his suit are red magnetic pads, used to carry onto Baymax's armor for transportation and battle purposes.


Big Hero 6

Hiro Hamada is a 14-year-old robotics genius living in the futuristic city of San Fransokyo. After graduating from high school, he spends much of his free time participating in illegal robot fights. To redirect Hiro, his elder brother Tadashi takes him to the research lab at the San Fransokyo Institute of Technology, where Hiro meets Tadashi's friends, GoGo, Wasabi, Honey Lemon, and Fred. Hiro also meets Professor Robert Callaghan, the head of the university's robotics program. Amazed, Hiro decides to apply to the university. To enroll, he signs up for the school's science fair and presents his project: microbots, swarms of tiny robots that can link together in any arrangement imaginable using a neuro-cranial transmitter. Hiro declines an offer from Alistair Krei, CEO of Krei Tech, to market the microbots, and Callaghan accepts him into the school. When a fire breaks out among the exhibits, Tadashi rushes in to save Callaghan, but the building explodes moments later, killing Tadashi and (apparently) Callaghan, and injuring everyone else inside.

Weeks later, a depressed Hiro inadvertently activates Baymax, the inflatable healthcare robot that Tadashi created, who follows Hiro's only remaining microbot to an abandoned warehouse. There, the two discover that someone has been mass-producing the microbots and are attacked by a man wearing a Kabuki mask who is controlling them. After they escape, Hiro equips Baymax with armor and a battle chip containing various karate moves and they track the masked man to the docks. GoGo, Wasabi, Honey Lemon, and Fred arrive, responding to a call from Baymax, and the masked man chases the group. The six escape to Fred's mansion where they decide to form a high-tech superhero team to combat the villain.

The group tracks the masked man, who they suspect to be Krei, to an abandoned Krei Tech laboratory on an island which they discover had been used for teleportation research until a test pilot was lost in an accident. The masked man attacks, but the group manages to knock off his mask, revealing the man to be Callaghan who had stolen Hiro's microbots to shield himself from the explosion on campus. Hiro realizes that Tadashi died without reason, while Callaghan refuses to take responsibility for Tadashi's death. This prompts an enraged Hiro to remove Baymax's healthcare chip, leaving only the battle chip, and to order him to kill Callaghan. Honey re-installs the healthcare chip at the last second, preventing Baymax from carrying out the kill order. Callaghan escapes, and Hiro leaves with Baymax, intent on avenging Tadashi. Back home, Hiro tries to remove the healthcare chip again, but Baymax stops him and states that vengeance is not what Tadashi would have wanted. To calm him down, Baymax shows Hiro videos of Tadashi running numerous tests during Baymax's development as a demonstration of Tadashi's benevolence and legacy. A remorseful Hiro apologizes to his friends, who reassure him they will catch Callaghan the right way.

Video footage from the accident reveals that the pilot was Callaghan's daughter Abigail and that Callaghan is seeking revenge on Krei. Callaghan interrupts Krei at a public event and attempts to destroy his headquarters using Krei's teleportation portal. After a lengthy battle, the team deprives Callaghan of his microbots and the mask, saving Krei, but the portal remains active. Baymax detects Abigail inside, alive but in hyper-sleep, and leaps into the portal with Hiro to rescue her. They find Abigail's pod, but on the way back out, Baymax is struck by debris, damaging his armor and disabling his thrusters. Knowing that the portal will collapse, Baymax uses his armor's rocket fist to propel Hiro and Abigail back through the portal, forcing them to leave him behind. Callaghan is arrested while Abigail is taken to the hospital. Sometime later, Hiro discovers Baymax's personality chip clenched in the rocket fist. He rebuilds Baymax's body and the six friends continue their exploits through the city, fulfilling Tadashi's dream of helping those in need.
