Lore & Background
San Fransokyo is defined by its role as the backdrop for high-stakes scientific discovery and conflict. The city houses the San Fransokyo Institute of Technology, a hub where students like Hiro Hamada, Go Go Tomago, Wasabi, Honey Lemon, and Fred gather. It was here that Professor Robert Callaghan demonstrated his microbots—devices capable of linking into any configuration via a neural transmitter. The city's infrastructure also supported secret projects like Krei Tech's teleportation research on a remote island. When a prototype portal destabilized, it trapped test pilot Abigail Callaghan, setting off a chain of events that turned the city into a battleground between heroes and the masked villain Yokai.
In Their Own Story
The narrative begins in San Fransokyo's underground robot fight clubs, where 14-year-old Hiro Hamada competes before his brother Tadashi takes him to the Institute of Technology. After Hiro impresses the school with his microbots, a fire breaks out at the university while Professor Callaghan is inside; Tadashi rushes back and perishes in the explosion. Two weeks later, Hiro accidentally reactivates Baymax and follows a rogue microbot to an abandoned warehouse, discovering Yokai mass-producing them. The group tracks the villain to Krei Tech's island lab, unmasking him as Callaghan. In the climax, Callaghan reactivates the unstable portal at Krei Tech headquarters, but Hiro and Baymax enter to rescue Abigail, destroying the portal in the process while saving the city from further destruction.
