Kazuya Mishima

Kazuya is the son of Heihachi Mishima. His father hoped for Kazuya to be strong to be the next leader of the Mishima Zaibatsu, but Kazuya was a kind and weak child. Heihachi being fed up with Kazuya's weaknesses threw him off a cliff stating, that he can only be his successor if he will survive the fall and climb back up. Kazuya did that, but with a price. He made a deal with the Devil.

He then grew up to be a great fighter and was unbeatable around the world. Heihachi announced the King Of Iron Fist Tournament. Kazuya joins and reaches the final where he fought his own father and won. He then threw his father off the same cliff as an act of revenge.

Kazuya took over the Mishima Zaibatsu and in his command it became more corrupt than ever before. It was because Kazuya was under the influence of the Devil. Two years later he announces the second King Of Iron Fist Tournament. During the tournament he met Jun Kazama and had relations with her, which led to his son being born. That son is Jin Kazama. In the finals he met Heihachi, who survived the fall off the cliff. While Kuzuya was confused by the inside struggle of Devil and Angel inside of him Heihachi defeated him and tossed his body into a volcano.

Kazuya's body was found by the G Corporation and resurrected. They wanted to learn about his Devil Gene and Kazuya made a deal with them. They will study his body and make him in control of his Devil Gene. Years later Tekken Force attacked the G Corporation research facility only to find Kazuya alive. He took out the Tekken Force and made his way to the recently announced fourth King Of Iron Fist Tournament. In the finals he fought his father for the third time and won. Heihachi brought him to Hon-Maru where he kept Jin. The Devil within Kazuya wanted to make himself whole again by extracting his lost half from Jin, but he was unable to do so because of the Kazama blood. After that Kazuya had full control of the Devil and could use his power at will.

But that didn't help him against Jin and Kazuya was defeated by his own son.

When he regained his conscience the Hon-Maru was attacked by Jack-4 robots, who were send by the G Corporation. He fought them off alongside Heihachi, but in the heat of battle he threw his father in to a pile of Jack robots and flew transformed in his Devil form right before the explosion, that destroyed the Hon-Maru.

He soon learns about the fifth King Of Iron Fist Tournament and joins to get the revenge against Heihachi and Jin, but he soon learns that none of them are responsible for the tournament. The tournament was held by Jinpachi Mishima, Kazuya's grandfather. He lost to Jinpachi and left.

After the tournament he attacked the G Corporation for betraying him. He killed everyone and took over the corporation. He now was in the command of the only force to able to counter Jin's world domination plans. To make things easier he announced a reward on Jin's head. But with the announced King Of Iron Fist Tournament 6 he decides take matter into his own hands and beat Jin.
