Hanging around at Fred's Mansion and reading comics, Fred decides to help give Baymax a brand new alter ego, even though his alter ego is a Personal Healthcare Companion. Through a series of ideas, Baymax dresses up in many different costumes that would suit his new alter ego. He tries a cowboy, a biker, a firefighter, and much more. All which Fred rejects. However, after Baymax tries on a sumo look, Fred forgets about finding him an alter ego and challenges him to a sumo wrestle. Dressed in a sumo costume, he charges at Baymax, but bounces back off his inflated body and hurts himself.
