Kintoki

is a giant bear that lives on the island where Killer B and A trained at.

Appearance
Kintoki is a predominantly black bear with white patches of fur on his arms, legs and head while his paws and body are covered with black fur. He also has a mark that runs over his right eye that resembles an eye patch.

Confining the Jinchūriki Arc
When B beats him in a sumō match, he tells Kintoki that he has got soft. He was later seen along with King and the other bears, watching Might Guy with interest as he opened his sixth gate.
