Tekken 5: Dark Resurrection

In the wake of the King of Iron Fist Tournament 4, Jin Kazama defeats his father, Kazuya Mishima, at the Mishima Zaibatsu's Honmaru temple. Disgusted by Kazuya's weakness, Heihachi Mishima challenges Jin, only to be overpowered when Jin unleashes his Devil form — though Jin regains control at the last second, sparing Heihachi and walking away. Moments later, Honmaru comes under attack by an army of Jack robots from an unknown source. Heihachi and Kazuya are forced to fight back to back against the onslaught, but as it intensifies, Kazuya betrays his father and flees. The temple is destroyed in a massive explosion, leaving Heihachi presumed dead. As a mysterious figure watches the destruction and reports his death, the Mishima Zaibatsu appears to be collapsing — until an unknown new leader swiftly seizes control and rebuilds its power. A month later, the Zaibatsu announces the King of Iron Fist Tournament 5, setting the stage for a fresh conflict.
