Jinpachi's age is unknown.
No,Jinpachi is Heiachi's father.
Jinpachi is the father of Heihachi, grandfather of Kazuya, and the great grandfather of Jin. Although Jinpachi was the founder of The Iron Fist Tournament, Heihachi locked him up in the Mishima Zaibatzu dojo, and when Jack 5s blew the place up, Jinpachi became free and reopened The Iron Fist Tournament with Jinpachi at the top. Also, he was the first to receive the devil gene. Although i don't know why Heihachi didnt receive the gene.
Heihachi is an old man in a game called Tekken and is the father of Kazuya, grandfather of Jin, and the son of Jinpachi, which comes out the first time in Tekken 5
Jinpachi's age is unknown.
Lee Chaolan, Heihachi, Jinpachi and Raven likes Kazuya. Even, Jin knows him, but Devil Kazuya, Asuka and Jun don't.
Jin or Kazuya probably...
Jinpachi Mishima was possessed by a supernatural entity known as the Devil, which led to the creation of the Devil Gene in his family line. Jin and Kazuya inherited this gene from Jinpachi, while Heihachi did not. This difference in gene inheritance is a key plot element in the Tekken series and drives the conflict between the Mishima family members.
He was 54 years old.
Asuka Kazama, Heihachi Mishima, Kazuya Mishima, Lee Chao Lan(adopted), and Jinpachi Mishima
He's the son of Jinpachi Mishima, the father of Kazuya Mishima and Lars Alexandersson, the adopted father of Lee Chaolan, and the grandfather of Jin Kazama.
Im pretty sure that Kazuya was thrown off a cliff by Heihachi, and received the devil gene in the extinct volcano that he was thrown in, then it spread towards Jin as well, but Heihachi didnt get it, so that's why he was looking for them Then why is Jinpachi like that then?
He's the son of Heihachi Mishima, the long time CEO of a powerful worldwide conglomerate Mishima Zaibatsu, and grandson of Jinpachi Mishima. He has a foster brother, Lee Chaolan, who was adopted by Heihachi Mishima, and also a half brother, Lars Alexandersson, Heihachi's illegitimate son. Most importantly, he is the father of Jin Kazama, through a relationship with Jun Kazama.
