Heihachi Mishima

Heihachi was born in a rich and respected family. His father was Jinpachi Mishima. In time Heihachi had a son. His name was Kazuya. Heihachi wanted his son to be strong and powerful to be the next leader of the Mishima Zaibatsu, but Kazuya was actually weak and kind child. With time Heihachi stole the Zaibatsu from his father. After Jinpachi tried to take it back Heihachi imprisoned him and made the Mishima Zaibatsu a military company.

With time Heihachi became fed up with Kazuya's weakness and tossed him off a cliff stating that if he was his son, then he will survive this fall and climb back up. Kazuya did that, but with a price. He sold his soul to the Devil. Heihachi also adopted a young boy, who he raised as his sons rival. That boy's name was Lee Chaolan. With time Kazuya became a great fighter who was unbeaten around the world.

Once the time has come for Heihachi to test his sons strength he announced the very first King Of Iron Fist Tournament. Kazuya managed to beat his father at the end and in revenge tossed him off the same cliff and took over the Mishima Zaibatsu.

Heihachi survived that fall and returned two years later to compete in the second King Of Iron Fist Tournament. He managed to defeat his son. After his victory he took Kazuya's unconscious body and threw him into a volcano. With that he once again became the leader of the Mishima Zaibatsu.

15 years later Heihachi created the Tekken Force. This organization once stumbled upon ancient ruins, where they found Ogre, The God Of Fighting. Ogre destroyed everyone who was there. Later a young boy found Heihachi and told him that he is his grandson. That boy was Jin Kazama. Heihachi took the boy in and thought him how to fight. He planed to use Jin as bait for Ogre. Years later Heihachi announced the third King Of Iron Fist Tournament. His plan was to gather as much fighters as he can to lure Ogre to him. The plan worked and Ogre was defeated by Jin. Heihachi betrayed Jin by shooting him in the back. But Jin managed to survive and escape.

Heihachi wanted to inject the power of Ogre into himself, but couldn't because he lacked the Devil Gene. He started a search for Jin to extract the gene from him, but was unsuccessful in locating him. Heihachi later found out that G Corporation was doing experiments with Kazuya's body. In hopes to retrieve the Devil Gene from him Heihachi led and attack on G Corporation's headquarters only to find Kazuya alive.

Heihachi had a plan. To lure the both Devil Gene hosts to him he will announce the fourth King Of Iron Fist Tournament. He will make Jin and Kazuya fight eachother and then beat the weakened winner himself. He captured Jin and fought Kazuya in the finals. Kazuya won and after his defeat Heihachi brought Kazuya to Hon-Maru where Jin was held. He set his plan into motion, but it backfired. Jin defeated both of them in his Devil mode and escaped.

Right after that the Hon-Maru was attacked by an army of Jack-4 units. Heihachi fought them off, but one of the robots activated a bomb and blew up the Hon-Maru with Heihachi. But Heihachi survived the explosion.

When Heihachi awoke from the explosion he found out that the fifth King Of Iron Fist Tournament was already announced and over. He went back to Mishima Zaibatsu headquarters, but he was denied access. He found out that Jin Kazama is the head of Zaibatsu now. Heihachi filled with anger decides to enter the sixth King Of Iron Fist Tournament to defeat Jin and return everything, that was once his.
