Hiro Hamada is the protagonist of Disney's 2014 animated feature film Big Hero 6. He is a fourteen-year-old robotics prodigy living in San Fransokyo under the care of his aunt and older brother Tadashi. After Tadashi's sudden death at the hands of a kabuki-masked villain, Hiro—with support from his healthcare companion, Baymax—became the founder and leader of Big Hero 6. Hiro is based on Hiro Takachiho from the Marvel comic of the same name.
