Baymax is one of the primary protagonists of the Disney's animated feature film Big Hero 6. Based on the Marvel character of the same name, Baymax is an inflatable robot created by Tadashi Hamada, whom he designed to work as the healthtaker companion of the San Fransokyo Institute of Technology. Following Tadashi's death, Baymax is taken under the care of his brother, Hiro Hamada. Since then, he appears as the secret weapon of the Big Hero 6, a team founded by Hiro to fight crime in the city of San Fransokyo. Of particular note, Baymax is programmed with considerably impressive strength, as well as the ability to access data throught the city. His battle armor is also immensely invulnerable to enemies' attacks and, thanks to Hiro's chip and tai-chi videos, he is also knowledgeable in martial lessons, which he uses against challenging foes.
