This eventually came to a head one fateful night. Initially, Heihachi tried to dismiss these incidents as some sort of illness, but in truth, Kazumi was the first known bearer of the Devil Gene, which had partialy compelled her violent outbursts. She would sporadically show signs of sickness and randomly lash out at Heihachi violently, trying to attack him with an almost demonic fervor. However, soon afterward, Kazumi began acting strangely and showed odd signs of not being herself. Eventually the two fell in love and married, giving birth to Kazuya. In the past, Heihachi spent his days studying the martial arts under his father Jinpachi's tutelage, alongside a fellow student named Kazumi Hachijo. He now continues the war against G Corporation and Kazuya, hoping to engage in one final battle to decide their fate.īefore his decisive battle, Heihachi would finally reveal his side of the story to a lone reporter who had collaborated with Lars Alexandersson. With Jin out of commission, but still alive unbeknownst to anyone, Heihachi seized control of the Zaibatsu. This pays off when, in the end, Jin sacrifices himself to stop the being known as Azazel and Kazuya leaves out of boredom. As Lars leaves, he surmises that Lars will end up doing his work for him, and continues to lay low. During Scenario Campaign, his plans to take back the Zaibatsu are interrupted in their early stages when Lars shows up and confronts him, revealing that he is Heihachi's son from an affair he had in the Netherlands. Heihachi survived, being no ordinary man, but was rendered unconscious for the entirety of the 5th tournament while Jin took over the Zaibatsu.

Jin foils his plan, then he gets ambushed by Jack robots, then Kazuya betrays him, and the Jack robots self-destruct on him after dogpiling him. Later he found out that Kazuya was still alive, and hosts the 4th tournament to lure his descendants for his plans. Once Jin beats Ogre, Heihachi betrays Jin by shooting him in the head, only to be smacked back by Devil Jin and thrown out of Ogre's temple through a wall.

When he's approached by his grandson Jin Kazama, who wants to avenge his mother's death at the hands of Ogre, Heihachi uses him to lure Ogre out. For years, Heihachi built up a good reputation with his Zaibatsu while hiding his ambitions.
