Kazuya Mishima (Japanese: 三島 一八 | Hepburn: Mishima Kazuya) is one of the main characters in the Tekken series. He appears in all Tekken games except Tekken 3, in which he only made two cameo appearances. Although he is seen as the main protagonist and hero of the first Tekken game, Kazuya became one of the major antagonists of the series ever since Tekken 2. Most importantly, Kazuya is the son of Heihachi Mishima and Kazumi Mishima, the possible love interest of Jun Kazama and the father of Jin Kazama. He's also the half-brother of Lars Alexandersson, the adoptive brother of Lee Chaolan, and the grandson of Jinpachi Mishima.
