It also saw the canonical returns of many characters absent from Tekken 4 and Tekken 3, contributing to a feeling of celebration for the series' tenth anniversary. Originally released in late 2004, Tekken 5 marked a turn from many of the mechanics introduced in Tekken 4. Trapped by his ruthless son underneath their family's own ancestral place of worship for decades, Jinpachi has been possessed by a demon and upon his liberation has to hastily announce a new King of Iron Fist Tournament to find literally anyone to stop him before he succumbs to his demonic influence. Unfortunately for the rest of the planet, the explosion also released a dormant entity capable of mass destruction: Heihachi's father, Jinpachi Mishima. The Jack robots activated their self-destruct feature and engulfed Heihachi's stronghold with Heihachi still in it.
