Mr. Yama

"NO ONE hustles Yama!"

- Mr. Yama intimidating Hiro after losing the bot fight.

Mr. Yama is a minor antagonist of the 2014 Disney film, Big Hero 6, which is based on the comic of the same name published by Marvel Comics. He is the bot-fighting champion that Hiro Hamada (the hero of the film) challenged against.

History
He is first introduced as the undisputed bot-fighter champion in San Fransokyo's illegal bot fights with his prize robot, Little Yama. After defeating an unfortunate contender girl, Hiro Hamada shows up and asks if he can participate with his own robot. Yama, underwhelmed by Hiro's naive demeanor, agrees to fight the boy. When Hiro's bot seems to collapse after the first round, Yama is about to gloat in his victory until Hiro bribes him with more money for a rematch. The confident Yama accepts this and the match restarts.

However, Hiro's bot is revealed to be highly advanced, quickly repairing itself and destroying Little Yama with ease. Hiro brazenly boasts about his victory until Yama, out of spite, has his goons attack the boy and chase him into the alley. When the group seems to have Hiro cornered, Hiro's brother Tadashi rescues him on his moped away from the goons.

The brothers, along with Yama's gang and everyone in the bot fights, are caught and arrested by the San Fransokyo police during the escape. Yama and his gang are forced to share a cramped cell with Tadashi, while Hiro has a separate cell to himself due to being a minor. Hiro and Tadashi are released that same night on account of their aunt Cass, while Yama is presumably left in prison.
