In 2014, Disney released Big Hero 6, an animated science fiction film loosely based on a series of Marvel comics by the same name. Set in San Fransokyo, a fictionalized combination of San Francisco and Tokyo, the movie centers on brothers Hiro and Tadashi, who are local engineering prodigies. Protagonist and younger brother Hiro builds small battle bots in his spare time, entering them in underground bot fights. Elder brother Tadashi uses his talent for more altruistic means, creating an inflatable robot named Baymax, designed to provide medical assistance.
