Kuma

The younger Kuma is the son of Heihachi Mishima's pet, the first Kuma. Raised and trained in the Mishima style of fighting arts, learning of his father's defeat, Kuma Jr. decides to train with his master and enter The King of Iron Fist Tournament 3. However, he fails, and realizes that due to his docile upbringing by Heihachi, he could not utilize his animal instincts to his full potential. Leaving Heihachi, Kuma Jr. travels to the mountains of Hokkaidō to train himself, both mentally and physically.

Now hearing of The King of Iron Fist Tournament 4, Kuma enters, more powerful than ever to defeat Paul. He succeeds, and he quickly returns home in triumph.

Now learning that Jinpachi Mishima has taken over the Mishima Zaibatsu, Kuma once again takes his role of the loyal pet, vowing to return the syndicate to Heihachi by entering the King of Iron Fist Tournament 5, but he is defeated by Paul.

After the death of his former master, Heihachi Mishima, Kuma believed no one but he could rescue the Mishima Financial Group (MFG) from its captor. Eager to do just that, Kuma confronted the MFG. However, the MFG's new CEO, Jin Kazama, was waiting. Kuma was easily beaten and discarded in the Hokkaido wilderness. Though defeated, his fighting spirit was not lost and he found his former master Heihachi.
