This page is for Hiro Takachiho, the character from Marvel Comics. For the character from the film, see Hiro Hamada.
It doesn't matter that this all happened before we were born -- the responsibility is ours to bear... the world still ours to protect.

Hiro Takachiho is a young super-genius who is the leader of the Big Hero 6 team and creator of Baymax, his personal shape-shifting robot bodyguard.


Hiro Takachiho was born to wealthy industrialists Tomeo Takachiho and Maemi Takachiho and was raised in the rich Tokyo suburb of Yōga, City of Setagaya. Hiro was gifted with super-intellect, a trait that his parents recognized and had him enrolled into pre-school at age 2. As Hiro grew up, he was soon recognized as one of the world's most brilliant child prodigies and was accepted into the private Tesuka Advanced Science Institute. It was there that young Hiro's aptitude for invention was discovered. At some point, Tomeo passed away, and in order to fill the void of his father, Hiro created his first and greatest invention, Baymax.

Although he is only an adolescent, he is a visionary theoretician and accomplished machinesmith who has already made several breakthroughs in fields such as robotics, computer science, synthetic polymers, geology, biology, and communications.


Hiro is a brilliant child prodigy because of his gifted intellect. However, he is still young, so he must deal with the transition from child to adult as he grows up, from experiencing depression to learning how he can cooperate with others. Hiro is overall heroic and possesses a sense of integrity. He greatly cares about his parents, as the death of his father was what motivated him to build Baymax to have a father figure. At times however, Hiro feels isolated from others because of his intellect, making it difficult to communicate with other children from his age. Hiro idolizes Sunfire and has a crush on Honey Lemon.


Hiro began with a bowl haircut, plain t-shirt and jeans during his early appearances, but in the 2008 comic series, he sports an anime-styled haircut (inspired by Samurai Champloo's Mugen[1]), a Yoshimuri Giants tee, jacket, and Sketchers-type shoes.
