One of the robotic heroes who will be fighting evil forces in Disney-Marvel's upcoming animated superhero movie, “Big Hero 6” is a mix between the Stay Puft Marshmallow Man and the Michelin Man.

The first trailer reveals that's problematic, because his inventor — a brilliant robotics prodigy named Hiro Hamada living in high-tech city of San Fransokyo — needs him in fighting shape. Or at least looking like he's in fighting shape.

Based on the Marvel comics of the same name, “Big Hero 6” follows Hamada and his robotic friend, Baymax, joining forces with a reluctant team of first-time crime fighters on a mission to save their city.

T.J. Miller, Maya Rudolph, and Jamie Chung provide voices for the CG-animated film that hits theaters on Nov. 7, TheWrap reported.
