Heihachi Mishima (三島 平八 Mishima Heihachi?) is one of the main characters in the Tekken series and he debuted in the first game in the series and has returned for all subsequent titles. Though seen as the protagonist of the second Tekken game, he is the anti-hero and one of the main antagonists of the series as he is almost always responsible for the events, though his impact on the story has seemed to decrease since Tekken 5. However, after being featured in the debut trailer of Tekken 7, Heihachi may become a pivotal part of the storyline once again.
Heihachi Mishima is the host of the 1st, 3rd, and 4th King of Iron Fist Tournaments. He is the son of Jinpachi Mishima, serving as the final boss of 1 and 4 and the sub-boss of 3. He is the father of Kazuya Mishima and Lars Alexandersson, adoptive father of Lee Chaolan, grandfather of Jin Kazama, and the husband of Kazumi Mishima. Heihachi's fighting style is Mishima Style Fighting Karate. He is also the "Commander" of the Tekken Force Unit.
Heihachi was born as the heir to the rich, powerful, and well-respected Jinpachi Mishima, owner of the powerful Mishima Zaibatsu and a world-famous martial arts master. During this time, Heihachi married the japanese woman Kazumi and eventually had a son with her named Kazuya. It is believed that his wife died while giving birth to Kazuya or not long afterward. Heihachi raised Kazuya harshly. Much to his chagrin, Kazuya grew up kind and frail, perhaps due to the more loving treatment he received from his grandfather Jinpachi (see Kazuya's Tekken 5 ending). At some point, Heihachi betrayed Jinpachi and stole the Zaibatsu from him. His motives for this act are as-of-yet unknown, but it can be speculated that Heihachi disagreed with his lack of aggression and his "soft" treatment towards Kazuya. After assuming control, Heihachi began to steer the Zaibatsu into the military industry. Jinpachi attempted to launch a coup to retake the Zaibatsu from his son, but failed and was ultimately imprisoned underneath Hon-Maru where he remained for 40-45 years until the events of Tekken 5.
Finally fed up with Kazuya's "weakness", Heihachi tossed his son down a deep ravine, claiming that if he were truly his son, he'd be able to survive the fall and climb back up. Kazuya actually managed to do so, but only because of the Devil Gene's presence in his blood. To further motivate Kazuya, Heihachi adopted an orphan named Lee Chaolan and raised him as a rival to his true son. It's assumed that Heihachi didn't care about Lee at all and only used him to irritate Kazuya. Over the years, Kazuya traveled abroad and competed in martial arts championships, becoming an undefeated champion (the only blemish on his record being a draw against Paul Phoenix). Eventually, Heihachi decided to test his son's strength so he announced the King of Iron First Tournament.
Much to Heihachi's surprise, he was beaten by Kazuya who ironically tossed Heihachi off a cliff. However, Heihachi managed to survive and he returns two years later as a competitor in The King of Iron Fist Tournament 2 hosted by Kazuya. He has a final showdown with Kazuya and defeats him. Afterwards, he tosses Kazuya (who had proven to be too dangerous) into a volcano and believed he killed his son.
Fifteen years after the King of Iron Fist Tournament 2, Heihachi is approached by a young man who claims to be his grandson who is none other than Jin Kazama. Heihachi takes him in and teaches him Mishima Style Karate for his own selfish purposes of using him as bait for Ogre. Heihachi also notices that Jin possesses the same "dangerous power" as his son and resolves to eliminate him after he's served his purpose.
During the King of Iron Fist Tournament 6 (which he secretly entered), he was defeated by Lars, who is later revealed to be his illegitimate son.
Heihachi is the host of this tournament. During this tournament, Heihachi was defeated by his son, Kazuya Mishima. Kazuya took over the Mishima Financial Empire, and he ruled it to his heart's content.
Version 1: Beaten 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.
Version 2: Ever since his son, Kazuya Mishima took over the Mishima conglomerate, Heihachi has been training to regain what was once his. After he defeats his son and watches the death of Kazuya, Heihachi will gain back the Mishima Financial Empire.
Ending Description, "A Son's Fall": Heihachi is seen walking while holding an unconscious Kazuya in his arms. This takes place after Heihachi has defeated Kazuya and won The King of Iron Fist Tournament 2. Heihachi drops Kazuya's body in a volcano. Heihachi is shown leaving by helicopter while holding onto a ladder. The volcano erupts, and then a closeup of Heihachi smiling is shown.
Family matters... Heihachi retrieved the Mishima Financial Empire by defeating his son.
Scheming to further develop the MFE, Heihachi organized "Tekken Force", the MFE's private corps, and dispatched them to settle disputes and bring wasteland under cultivation to feed the poor countries of the world, in order to gain the support of leaders worldwide.
Fifteen years later, a secret excavation of Central American ruins by the Tekken Forces unearths an unusual find. They were annihilated by a mysterious being. Heihachi realized that the mysterious being could be the legendary Ogre, and took action to realize his life's goal: to capture Ogre and therefore rule the world.
One day, Heihachi was visited by a 15-year-old boy named Jin Kazama. Being informed that Jin was his grandson and hearing what had happened to his mother, Jun, Heihachi reasoned that Ogre thrives on the "strong souls" of others. Heihachi trained Jin to use him as a decoy to lure Ogre.
In Jin's 19th year, Heihachi declared to the world that the third "King of the Iron Fist Tournament" was forthcoming. At the same time he noticed that Jin, the youngest of Mishima bloodline, began to show the same dangerous power Kazuya had. Heihachi decided to dispose of Jin after he lures Ogre, in order to end the doomed destiny of the MFE.
Ending Description, "A Grandson's Fall": Heihachi defeats True Ogre, and True Ogre dissolves into nothing. Heihachi takes a moment to rest. He notices Jin laying on the ground, unconscious. Next, some helicopters are shown flying in the sky. Heihachi and Jin, who is still unconscious, are aboard one of them. Jin is laying down on what appears to be a stretcher, and Heihachi is sitting next to him. A short while later, Heihachi notices that devil markings are appearing on Jin's forehead. After, Heihachi picks Jin's body up and throws it out of the helicopter then watches Jin's body fall.
Two years ago, Heihachi failed to capture Ogre. He made his researchers collect blood and tissue left behind by Ogre and attempted to create a new life form by combining its genetic material with his own. The experiment failed, however, and Heihachi learned that he lacked the Devil Gene necessary to integrate Ogre's genome into his.
In order to obtain the Devil Gene, Heihachi searched for Jin, who transformed into a devil during the last Tournament. During the 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. They obliterated G Corporation's laboratory, and the mission appeared to be successful. That was until Kazuya, revived by G Corporation, retaliated and caused the mission to fail.
Heihachi needed Kazuya or Jin's body to create the new life form. After much deliberation, an evil smile crept onto Heihachi's lips.
The next day, an announcement was made for The King of Iron Fist Tournament 4, with the Mishima Zaibatsu as the prize.
Ending Text: Heihachi did not kill Kazuya outright. "Come with me if you want to see your son," Heihachi said, and led Kazuya out of the arena. A few hours later, the two were deep within the Mishima Zaibatsu compound. A massive temple stood in the midst of a forest enshrouded in fog.
The two entered the building...
Ending Description: Heihachi and Kazuya enter Hon-Maru. They notice Jin Kazama chained up and Kazuya gasps. Two chains wrap around Kazuya's arms, and then he is suspended in mid-air like Jin. A short while after Kazuya is suspened, two more chains wrap around his legs while he struggles to get free. Kazuya says, "You think this'll stop me?" while trying to get free. Heihachi says, "Did you think I'd be dumb enough--to let you in here without--a leash to tie you down? That chain has the ability to neutralize your powers. An individual saturated with the Devil Gene, such as yourself--will lose consciousness in a matter of minutes!" Heihachi laughs. Then, he says, "Now, all the pieces are in position! Be thankful that the two of you will die--helping me achieve my objective!" Heihachi laughs again, and then he starts to walk out of the building. White text on a black screen says, "Thereafter, the world came to know an age of darkness..."
Head of the Mishima Zaibatsu and sponsor of the King of Iron Fist Tournament 4, Heihachi Mishima.
After losing to Jin Kazama, Heihachi was cornered by a group of Jack robots in Honmaru. Heihachi and Kazuya began to fight off the Jacks together but Kazuya fled and Heihachi was caught in the explosion when the Jacks detonated.
The tremendous explosion would have killed a normal man but Heihachi, no ordinary man, managed to survive.
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. Heihachi, having fully recovered, was determined to enter the tournament.
"I don't know who's behind this but the Mishima Zaibatsu is mine!"
Ending Description: A rocket is shown while a female voice does a countdown, starting with thirty. The rocket is preparing to launch. It is revealed that Jinpachi, Kazuya, and Jin are strapped onto the rocket with chains. They all try to get free themselves, but fail. After the countdown is over, a female voice says, "Ignition!" The rocket is launched and all of them scream. Heihachi looks at their faces with binoculars and laughs until the ending video ends.
After being assaulted by the Jack force, Heihachi wakes up only to find out that the King of Iron Fist Tournament 5 has already ended. He goes back to Zaibatsu headquarters only to find the Tekken Force blocking his way. After the next Iron Fist Tournament is announced and Heihachi finds out that Jin Kazama is the new head of the Mishima Zaibatsu, he is enraged and declares that he will get everything back.
Ending Description: Located at a space station, Heihachi is seen, preparing to kick both Jin Kazama and Kazuya Mishima into space (all three wearing space suits, with Heihachi's additions of geta sandals on his own).
He proceeds to kick Jin into space....but Kazuya proved to be a REAL problem, as he begins to kick Heihachi twice (despite being bound), causing the latter to drift into space as well.
All three Mishima were left burning as shooting stars upon re-entry.
How he has his own followers/students in a new estate, remained unknown. He is soon heard that a rebel leader Lars Alexandersson will come after him, although he wasn't aware that Nina, under orders of Jin, patrols him, knowing that using Lars would further his plan to reclaim the throne back to him. Upon meeting Lars during a their fight, he finds out that Lars was his illegitimate son, who Heihachi unaware of, planning to kill him because Lars knows what the evil reputation Heihachi have? However, it fails because of Alisa's little interruptions and Heihachi himself can deflect a gun, using a mouth with a headbutt-like move, Lars then mocks him in to join circus due to his healthy body and current age. Lars and Alisa soon depart after Tougou calls them that they have found what Heihachi left behind, but not before telling him that he will be back for him after the war is over. When the guard tells if they should let him go, Heihachi tells him not to bother as it was already on his plan all along to reclaim Zaibatsu's throne.
To be add
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.
One of the most infamous scenes in this movie depicts Heihachi not only catching a tomahawk (thrown by Michelle Chang) with his bare teeth, but also biting it so hard the metal edge shattered.
Soul Calibur II
Heihachi Mishima is a playable character in the PlayStation 2 version of Soul Calibur II.
Heihachi Mishima appears in the live-action film portrayed by actor Cary-Hiroyuki Tagawa. He is initially a villain but becomes a much more sympathetic character than in the games, as he is willing to give his life to save Jin from the Tekken Corp soldiers. He is killed by his son, Kazuya Mishima, in his attempt to overtake Tekken. It looks as if Heihachi is killed near the end of the film. However, a post-credits scene reveals that he actually survived, saying "I am Mishima Heihachi. I am Tekken. You WILL obey!" to one of the Jacks.

Note: Namco's translation is not the literal translation.
The only person Heihachi hates the most of all is his own son. Heihachi treated him like dirt since he was a child due to his training method. Kazuya was kind and frail, perhaps due to the more loving treatment he received from his grandfather, Jinpachi, and Heihachi believed that kindness was for the weak.
Due to Heihachi's unwillingness to hand over the Zaibatsu, he tossed his son down a deep ravine, claiming that if he were truly his son, he'd be able to survive the fall and climb back up not realizing what he had done. Kazuya had awakened the Devil Gene inside of him, which enabled him to climb back up. After this, Heihachi saw the error of his way and realized what kind of monster he had created. Despite this, as Heihachi grew old, he wanted the power of the Devil Gene to gain eternal life.
Being the adoptive father of Lee, Heihachi never actually felt any emotion towards Lee and only used him to irritate Kazuya. However, Heihachi was impressed by Lee's street-fighting skill and decided to adopt him so he could rival with Kazuya and educated him back in Japan. There were times that Heihachi would put Lee in important roles from the Mishima Zaibatsu like sending him to the U.S to handle the operations and to continue his business education before the events of the original Tekken. Throughout the years, Heihachi still doesn't care about Lee.
Lee shows no respect for Heihachi as seen in his endings each showing he is trying to either beat up, kill or even humiliate Heihachi.
Heihachi took Jin under his wing and trained him to fight Ogre. He announced the King Of Iron Fist Tournament 3 in hopes of bringing together the most powerful fighters from across the globe to lure and capture Ogre. Unlike his relationship to his son Kazuya, Heihachi had a more friendly relationship with Jin in Tekken 3 and served as a father figure to the young fighter. Jin looked up to his grandfather and trusted him with his life. When Heihachi realized he had the Devil gene in his blood, he betrayed Jin to extract the Devil gene. After Heihachi's betrayal, Jin lost all respect for his grandfather and started to despise everything about his bloodline.
One of the only people Heihachi ever cared about other than himself was Kuma I. Heihachi trained Kuma in the arts of Kuma Shinken.
After the death of Kuma, Heihachi took care of the cub and named him Kuma Jr. Though he loves Kuma Jr, there are times Heihachi would trick Kuma Jr. As seen in Kuma's Tekken 4 ending, Kuma is signing some documents (by placing his paw print on it) that will officially hand the Zaibatsu over to him; but the last document reads Heihachi will get the Zaibatsu back from Kuma, thus causing Kuma to place his paw mark on Heihachi's face rather than on the document, thus outsmarting Heihachi. He can be frustrated as seen in Kuma's Tekken 5 ending with Heihachi saying, "Damn Kuma and his worthless hide... As long as there's a breath left in my body, I won't let you do as you please!"
In Soul Calibur 2 (PS2), Heihachi even mentioned Kuma at the end of his fight with Inferno saying "Even Kuma is stronger than you."
After hearing about this young Rebel Leader from his men, Heihachi gave orders to find Lars so that he could join forces with him. At this moment, Heihachi was staying at his estate and plotting to get the Mishima Zaibatsu back. Lars, at this moment, was suffering from amnesia. After he was told by his friend Tougou about Heihachi, he searched for him and eventually found him at his estate. Afterwards, Lars faced him in combat and defeated him. After the fight, Lars's memory was recovered. Heihachi suddenly discovered that Lars was his illegitimate son after Lars reminded him about an operation he commanded in Scandanavia.
- Kazumi Mishima - His beloved wife. She is the only Mishima family member which he never hated and one of the only people Heihachi ever cared about other than himself. He then had a son named Kazuya with her. Kazuya mentioned in the debut tralier of Tekken 7 that Heihachi killed Kazumi for unknown reasons. Heihachi does regret for killing Kazumi, as he shed a tear for her in the full trailer.
- Doctor Abel - Abel worked for Heihachi and the Mishima Zaibatsu as a scientific adviser in Tekken 4, before he was knocked out by Bryan Fury.
- Michelle Chang - He stole her amulet and used it to resurrect Ogre. It is unknown why he did this. He also held Michelle Chang's family hostage and later murdered them. He later kidnapped her prior to Tekken 3.
- Ogre - Heihachi witnessed the power of Ogre, and seeked to capture it in hope of creating the ultimate life form during the King of Iron Fist Tournament 3. Later in the fourth tournament, Heihachi's scientists capture samples of Ogre's blood and tissue in order to splice Ogre's DNA with Heihachi and make him immortal, but the experiment fails since Heihachi lacks the necessary Devil Gene in his blood.
- Nina Williams - He was her assassination target during the first tournament.
- Ling Xiaoyu - Promised her that he would build her an amusement park if she won The King of Iron Fist Tournament 3.
- Mr. Rochefort - Seems to be his business partner.
- Raven - Fought him after the fifth tournament. However, Raven received orders to return to headquarters, which forced Raven to withdraw from the fight before a victor could be decided.
- Yoshimitsu - Heihachi was robbed by him in Tekken 4.
- Prototype Jack - Entered him in the first King of Iron Fist Tournament to defeat his rival upgrade Jack.
With so many devastating and over-the-top moves, Heihachi is one of the best choices for players who like aggressive strategies. His damage potential is insanely high, and most of his best moves have little to no risk. For example, his infamous Demon Uppercut is a very damaging launcher, easy to perform, and almost impossible to punish if blocked.
Unlike Kazuya, Heihachi doesn't have any troubles into pressuring the opponent with pokes, and like every Mishima he has great punishers, although Kazuya's and Devil Jin's are much more varied and useful.
