Also known as: 三島仁八
Tekken character.
He was the original CEO of the Mishima Zaibatsu until his son Heihachi imprisoned him under Honmaru for years, thus passing the title of Zaibatsu CEO to Heihachi.
It wasn't until Tekken 5 when Jinpachi freed himself from the chains that imprison him under Honmaru and reclaimed the title of Zaibatsu CEO, when Heihachi is rumored to be dead by an unknown secret agent who uses Raven as a codename.
He was eventually defeated by Kazama Jin, thus passing the title of Zaibatsu CEO to Jin prior to Tekken 6.
