Big Hero 6
In the futuristic city of San Fransokyo,[b] Hiro Hamada, a 14-year-old high school graduate and robotics prodigy, spends his time competing in illegal underground robot fights. Hoping to get him out of this dangerous lifestyle, Hiro's older brother Tadashi takes him to attend the San Fransokyo Institute
of Technology, where Hiro meets Tadashi's closest friends – gritty Go Go, neurotic Wasabi, bubbly Honey Lemon and comic book fan Fred. Tadashi also introduces Baymax, an inflatable healthcare robot, which he invented. After meeting Tadashi's mentor Professor Robert Callaghan, Hiro applies to
the university, impressing the school's showcase with his project: a swarm of microbots that can link together in any configuration using a neural transmitter. Hiro is accepted, but the celebration is brief when a fire breaks out with Callaghan caught in it. Tadashi rushes back into the building to save him,
but an explosion occurs, killing him.
