We didn't set out to be superheroes. But, sometimes life doesn't go the way you planned. The good thing is, my brother wanted to help a lot of people and that's what we're going to do. Who are we? BIG HERO 6!

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, his 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, having graduated from high school at 13. Because of this, he can be rather brazen and cocky, but never to the point of arrogance. He spends most of his time using his technology to win money through illegal bot fights, something he prides himself on, though his older brother, Tadashi, heavily disapproves. Despite coming across as an 'insufferable genius' at times, as shown by his claim to Tadashi that going to college would be pointless (What? Go to college like you? So people can tell me stuff I already know?), it is shown that this is merely a façade to hide his deep insecurities, which become especially apparent during his presentation of his MIcrobots.
Indeed, Hiro has a much softer side to him, as he's shown to be rather shy in front of crowds and during the process of making new friends, as well as awkward at times. Even so, his compassion 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 are shown; 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, underneath his kind heart lies a darker core. At some points during the movie, the boy genius would allow 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 makes a serious effort to right the wrongs he's 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 do whatever 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 to fulfill Tadashi's lifelong dream of helping others.
Hiro is a smart and handsome boy. According to official sources, he is 5'0" in height, and can often be found in his blue hoodie jacket, a red shirt, long dark beige shorts, and dark brown trainers with yellow laces. He's fair in the skin and has black hair and brown eyes. When he smiles, a gap in his teeth can be noticed. Hiro's super-suit is made of primarily deep purple, red 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.
Powers and Abilities
Unlike the rest of the team, Hiro's armor lacks any real ability, as his true power lies within his intelligence. As mentioned above, however, his suit enables him to hold onto Baymax whenever the robot takes flight with him aboard, as well as partial protection from destruction. His helmet is also equipped with a communication device, enabling him contact with the rest of the team members despite their distance, if any.
In the Big Hero 6 manga "Baymax", Hiro's story differs from the film. In the comic, Hiro is already attending the San Fransokio Institute of Technology with Tadashi and his friends. It is also shown that Hiro preferred to be in the company of machinery than with other people (except for Tadashi). When attending the science fair, Hiro has an argument with Tadashi over the latter wanting to attend a welfare college, which leads to Hiro nearly getting sucked into a portal created by Yokai, but is saved by Tadashi, who is sucked into the portal himself.
In the early drafts of Big Hero 6, Hiro, along with Tadashi, was going to be Cass's son rather than her nephew.
