Heihachi Mishima is a fictional character of Namco’s Tekken fighting game series as one of the main antagonists of the series. 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, in order to rid the world of the Devil Gene as reckoned in Tekken 7 whereas before he showed an interest in taking Jin’s Devil Gene power to perfect his youth formula that he was trying to create since Tekken 3 with Ogres DNA. He never successfully creates his youth formula in canon though although he has successfully created it in PlayStation All-Stars and Tekken Tag 2 which are both non-canon appearances of the character. Heihachi’s past and motives are revealed in Tekken 7, which is said to be his final appearance in the story.
