Kintoki

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

Appearance
Kintoki is a bear with white fur on his arms, legs and head. The fur on his paws and torso is black, as is a mark that runs over his right eye that resembles an eye patch.

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

Trivia
