He is one of only four characters (the others being Paul Phoenix, Nina Williams and Yoshimitsu) to have appeared in every game in the series and he makes two appearances within the series as the final boss (in both Tekken and Tekken 4).
He is also the only Tekken character aside from Yoshimitsu to be featured in the Soul series (he is a guest character in Soulcalibur II on the PlayStation 2 console).
Tekken series director Katsuhiro Harada has stated that Heihachi is his favorite character in the overall series. and the character he most frequently selects when playing. He further described Heihachi as a "very human character", stating that while focus had been placed on his appearance he found the character's philosophy more interesting, and that in the series he was a "perfect portrayal of the evil that lurks in mens' hearts", an evil "far more hideous than any made-up monster or demon." Heihachi's fighting style is not based on any existing style, and was instead created by the series' development team.
Heihachi is 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. He fights with Mishima Style Fighting Karate and is the founder and the Commander of the Tekken Force Unit. He has hosted half of the King of the Iron Fist Tournaments with the second, fifth and sixth King of Iron Fist Tournaments being hosted by Kazuya, Jinpachi, and Jin respectively.
