Having dealt with his sons' treachery, Heihachi, now the head of the Zaibatsu once more, founded his own private army, the Tekken Force. Likely at a similar time, he also founded the Mishima Polytechnical School, which masqueraded as a high school and polytechnical college, but doubled as a secret Tekken Force training facility. During the second tournament, Kazuya had imprisoned Nina Williams who had attempted to assassinate him. When Heihachi took over the Zaibatsu, Nina was frozen in experimental cryosleep machines. Heihachi kept her in this machine and had eggs harvested from her for use in a supersoldier program. The experiment claimed the lives of all the children involved, save one, and Heihachi had the experiment closed as a failure. Also during this time, Heihachi worked on the Zaibatsu's image and used Tekken Force to cultivate a benevolent image, sending them on humanitarian and peacekeeping missions. In actuality, Heihachi was hunting down a rumoured source of great power, a creature known only as Ogre. Possession of this creature's genetic material was rumoured to extended life and increase power. Heihachi succeeded in finding this creature, but, on awakening it in its temple in Mexico, the entire Tekken Force team on the mission was wiped out, and the creature vanished. Some sixteen years after Heihachi overthrew Kazuya, a fifteen-year-old boy came before Heihachi, claiming to be the son of Kazuya and Jun Kazama. The boy, Jin Kazama, drew Heihachi's interest when he claimed that his mother had been killed by a creature matching Ogre's description. At this time, Ogre seemed to be preying on the strongest martial artists. Utilizing the boy's desire for revenge, Heihachi undertook to train him, intending to use the boy to lure Ogre out into the open once he was strong enough.
Both Kazuya and Jin attended the tournament, but Heihachi interrupted the competition and kidnapped Jin before the semi-finals. After defeating Kazuya in the finals, Heihachi brought him to Hon-Maru, where Jin was being held captive. On meeting his son for the first time, Kazuya was possessed by his Devil, which then informed Heihachi that when Kazuya had been thrown into the volcano, Devil had been split in two, with half of it seeking out Kazuya's unborn son. Devil rendered Heihachi unconscious then proceeded to try and extract its other half from Jin. It was unsuccessful and, when Heihachi awoke, Kazuya was unconscious, and a semi-transformed Jin stood before him. Jin defeated Heihachi too, and drew back his fist to kill him. He spared him at the last moment, however, and again flew off. Moments later, a battalion of Jack robots arrived and Heihachi and Kazuya were forced to fight together in order to fend off the attack. When he saw the opportunity, Kazuya pushed Heihachi into the robots and flew off, now able to control his Devil at will. The robots detonated, blowing up the temple with Heihachi inside, and unleashed the sealed demonically-animated body of Jinpachi Mishima from beneath.
Heihachi is also incredibly tenacious. Despite setbacks and defeats at the hands of his son and grandson, he bides his time and makes miraculous returns to power, demonstrating his craftiness and adeptness at handling crisis situations. He has a code that applies both to martial arts and to life that he drilled into his sons: "A fight is about who's left standing. Nothing else", highlighting his divergence from a more honorable approach favored by his father. Although an excellent businessman, Heihachi is someone for whom violence takes precedence and has an almost sacred role. He at numerous times puts up his corporation as a prize for the Iron Fist Tournament, a tournament he himself founded, and frequently resorts to solving personal and business matters through the violence of his Tekken Force, or even by interceding himself. He commands the respect and fear of many of his employees, to the point where many remain loyal to him, even when he is no longer head of the Mishima Zaibatsu. Although he does not have the same honorable approach to fighting as Jinpachi (and arguably Kazuya), Heihachi often expresses a respect for women and claims that he is chivalrous, and also expects his Tekken Force to conduct themselves according to a chivalrous code of conduct (though he seems happy to break such a code when he orders them to abduct Jin Kazama from the fourth Iron Fist tournament, and had no qualms abducting Michelle Chang in order to use her as leverage).
Version 1Heihachi Mishima is the head of the Mishima Financial Group (MFG), sponsor of the tournament, and father to Kazuya Mishima. The MFG is the world's largest developer of military equipment. Heihachi is holding this tournament for the purpose of gathering the strongest soldiers for his own personal use. Heihachi Mishima is well versed in various forms of combat the world over.
Manual, NTSCBeaten by Kazuya in the previous tournament, in an instant he lost both his fame and family. Having spent his previous time indulging in deviant acts instead of training, he vows to regain what he has lost.
Manual, PAL*The PAL manual frames the character profiles as a Mishima Zaibatsu intel report.Following the management take-over at the conclusion of the last tournament, the subject has been living in seclusion in the mountains. All known pro-Heihachi elements within the Conglomerate have been dealt with - the coming tournament should be an excellent opportunity to close this file permanently. Known associates: Lee Chao Lan [sic] (though of course Lee's loyalty to K.M. and the Conglomerate is above question).
However, the experiment failed. Heihachi learned that he lacked the Devil Gene necessary to harness Ogre's powers. In order to obtain the Devil Gene, Heihachi searched for Jin, who transformed into a devil during the last tournament. During this search Heihachi learned that the body of his son Kazuya, whom he killed 20 years ago, was stored at a cutting-edge biotech firm called G Corporation. Heihachi ordered his Tekken Force to raid G Corporation in an attempt to obtain Kazuya's remains. Much to Heihachi's surprise, Kazuya, resurrected from the dead, thwarted the mission.
Summary of In-Game EventsAt the seventh stage of the tournament, Heihachi had his Tekken Force abduct Jin, overwhelming him by force and subduing him with a chain that suppressed his Devil Gene. This gave Kazuya an automatic win and he went on to face Heihachi in the finals. Kazuya demanded to see his son, and Heihachi told him he would take him to Jin after they fought.
A month later, Heihachi learned that someone had taken control of the Mishima Zaibatsu and planned to hold The King of Iron Fist Tournament 5. Having fully recovered, Heihachi was determined to enter the tournament.
Official Strategy GuideHeihachi was knocked unconscious when the JACK military units he was fighting self-destructed. When he came to, The King of Iron Fist Tournament 5 was already over. He went home, without any knowledge of the events that occurred at the tournament, where he was ambushed by the Tekken Force.
Afterward, the Mishima Zaibatsu announced The King of Iron Fist Tournament 6. Heihachi was furious when he heard that Jin had taken control of the Zaibatsu, and he left for the tournament to reclaim control of the Mishima Zaibatsu.
Shortly after the attack, the Mishima Zaibatsu announced The King of Iron Fist Tournament 6. Heihachi is furious when he hears that Jin has taken control of the Zaibutsu. He leaves for the tournament to reclaim control of the Mishima Zaibatsu.
However, Heihachi survives and returns to the Mishima Zaibatsu. With Akuma going after Kazuya and Jin still missing, he decides to take advantage of the situation. He orders the Tekken Force to announce his death and that the tournament is off. He then has the fight between Kazuya and Akuma broadcasted worldwide, exposing the former's devil form and turning public opinion against G Corporation. Afterwards, Heihachi launches a laser attack from a satellite, destroying G Corporation tower. Believing Kazuya to be dead, Heihachi laughs with his supposed victory. But when his satellite is suddenly destroyed by Kazuya, he is horrified to learn that his son had survived, and the Mishima Zaibatsu is under scrutiny once again for supposedly destroying its own satellite, which has fallen to earth and caused devastation.
Heihachi Mishima is featured in Tekken: The Motion Picture. In it, Heihachi is first shown throwing his son, Kazuya Mishima, off of a cliff at the age of five, stating that lions push their young off of cliffs and only raise the ones that manage to climb back up. Twenty-one years later, Heihachi hosts a martial arts tournament, dubbed The King of Iron Fist Tournament, on an island. Kazuya attends the tournament, having survived his fall and climbed back up by selling his soul to the Devil. Heihachi and Kazuya face-off near the movie's end. The battle is brutal for both of them, but, in the end, Kazuya emerges as the victor. Kazuya plans to kill Heihachi, but Jun Kazama manages to convince him not to. After Lee Chaolan sets the island to self-destruct, it is revealed that Heihachi has regained consciousness, and escapes from the island via airplane.
Heihachi is presented as scheming and manipulative throughout the show, lying to Jin in order to control him, including making Jin believe that he himself was to blame for Ogre's attack on his mother, when in fact Heihachi had unleashed Ogre into the world in the first place. As Jin hears more about Heihachi and the Mishima Clan from other tournament competitors, he grows apart from his grandfather, rejecting more of his teachings in favour of compassion. Heihachi grows increasingly irate over this, especially as Ogre has not yet shown up to the tournament. Eventually, Jin wins the tournament and Heihachi challenges Jin himself, telling him he has failed his mother, him, and his teachings. Jin surprises hHeihachi by using his Kazama Ryu however, and is eventually able to defeat Heihachi. According to Heihachi, the fight has forced Jin to draw enough on his latent devil power that Ogre is able to detect it. The Chang pendant glows with Ogre's presence and Ogre descends from the sky to fight Jin. After Ogre is defeated in both its forms, Jin's voice is distorted and his eyes are red. Heihachi claims this is the power of the devil and that he is doing the world a favour to rid it of it. He shoots Jin and Jin collapses. This triggers the final part of Jin's transition into Devil Jin. Devil Jin launches at Heihachi and pummels him into the ground, only stopping at Ling Xiaoyu and Hwoarang's request, before flying off into the night. 2b1af7f3a8
