Heihachi

Heihachi Mishima is one of the main villains in the Tekkenfighting video game series, as well as the most recurring one. A vile and power hungry monster, he is almost always responsible for the events of the games but his impact seems to decrease during the events of Tekken 5 and Tekken 6, after his last defeat and false death after Tekken 4, yet he is still the indirect reason of the events in those games as well. In Tekken 7, he seems to regain his prominence as a character and it is revealed that Heihachi himself wasn't directly responsible for the fued or the events that followed, but rather the only woman he loved, Kazumi Mishima.

Heihachi was the main antagonist of the first Tekken game, the protagonist and anti-villain of Tekken 2, the secondary antagonist of Tekken 3, the main antagonist of Tekken 4, a supporting antagonist for both Tekken 5 and Tekken 6, and the main antagonist of Tekken 7. He is also the main antagonist of the film Tekken: Blood Vengeance.

Heihachi has made several appearance in other non-canonical games and animations, either as playable character, a boss or main antagonist, or just cameos.

In the original Japanese versions, he is voiced by late seiyu, Daisuke Gōri, and Unshō Ishizuka
