As reported by Disney, Big Hero 6 is returning back as a tv show for the brother network Disney XD in 2017.
The series will pick up immediately after the events in the film. Hiro is now the newest prodigy at San Fransokyo Institute of Technology. The show will focus on two aspects the daunting academic and social challenges of being the big/little man on campus and the challenges Off campus, as the stakes are raised for Big Hero 6 as they must protect their city from an array of scientifically enhanced villains.
No word yet on the villains, but hopefully we can get some Marvel bad guys and get some animated character synergy. This is a Marvel property after all, even if it is separate from the MCU. At the least, can we get another Stan Lee cameo!?!
