Tadashi Hamada

Tadashi appears in "Big Hero 6" as Hiro's older brother. Due to their parents being deceased, Tadashi is Hiro's primary voice of reason and father figure. In the film, Tadashi and Hiro live in San Fransokyo with their aunt, Cass. Although his age is not explicitly described in the film, Tadashi acts very mature for his age. Additionally, Henney describes the character as "pure," even comparing Tadashi to an angel. Tadashi is also a "tech-wizard" who conceives, builds and programs Baymax.
