Baymax

Baymax is Hiro 's robot from the 2014 Disney animated feature, Big Hero 6. He was originally built by Hiro's brother Tadashi. He is based off of the orignal Baymax from the Big Hero 6 Marvel comics.

Appearance
Baymax is a large white robot with a very simplistic face. Since he was built to be a nurse, his body is covered with soft, white, pillow-like material (he is often referred to as "balloon man"). During the movie, he wears a red suit of armor designed by Hiro, which makes him appear to be more of a tough fighter robot.

Role in the Crossover
Baymax plays a huge role in Hiro's life as his surrogant older brother. Since Hiro is being added to the RotBTD crossover by fans, it is likely that Baymax plays a role in the crossover as well (as in cases such as Big Dragon Guardians ). As a funny and perceivably adorable sidekick, fans may often associate him with Toothless or Olaf.
