Jinpachi Mishima

Jinpachi Mishima (三島 仁八 Mishima Jinpachi?) is a fictional character as well as an anti-villain in the Tekken series. Despite being an main antagonist of Tekken 5, he appears to be remorseful about his wrongdoings as his evil aura consumes him. He is the father of Heihachi Mishima and the founder and former head of the Mishima Zaibatsu.

Personality
Unlike most Mishimas (who were ruthless and power hungry), Jinpachi was a man of honor and wisdom as he showed compassion to his grandson Kazuya when the latter was a child (this is possibly another reason Heihachi resented Jinpachi so much) and was friends with Wang Jinrei. In his Tekken 5 ending, realizing no one could stop him, he shed tears as the evil spirit that possessed him grew more powerful.

Also, Jinpachi is a perfect example for an anti-villain, as you can't help but empathize with him for his plight.
