Kazuya Mishima is the son of Kazumi and Heihachi Mishima. One day, Heihachi threw the five years old Kazuya into a deep ravine, to test him. This experience awekens something within him, giving him immense strenght and permanantly corrupted his personality. Whatever was left to his good side appears to be totally suppressed by his Devil persona, and the two have becomes fully fused. By dark936 #Tekken #KazuyaMishima #Kazuya #Mishima
