Heihachi Mishima (Japanese: 三島 平八, Hepburn: Mishima Heihachi) is a fictional character of Namco's Tekken fighting game series, serving as its main antagonist. Introduced as the boss character from the first Tekken video game from 1994, Heihachi appears as the leader of a military firm known as the Mishima Zaibatsu. He was the protagonist of Tekken 2 and Tekken 7. He was a boss character in two additional installments. He is opposed by many of his relatives who wish for his death out of revenge and to take over the Zaibatsu. This happens across the series and one of the creators of Tekken Katsuhiro Harada has called it a "family feud". Heihachi wants to defeat his son and grandson, Kazuya Mishima and Jin Kazama respectively. Heihachi's backstory and motives are revealed in Tekken 7, which is said to be his final appearance in story.
