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 an anti-villain of the second Tekken game, he is 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. But in Tekken 7, Heihachi is part of the main storyline once again and one of the two main characters of the game alongside Kazuya as well as the main antagonist of the game. (Although he could also be the protagonist as Tekken 7 mainly focuses on him and he was playable the most times in the game's story mode).
Heihachi Mishima is the host of the 1st, 3rd, 4th, and 7th 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 and 7. 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 inaugural "Commander" of the Tekken Force Unit, establishing the unit between the 2nd and 3rd tournaments.
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 sadly 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 suspended, 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 Hon-Maru. 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 their fight, he finds out that Lars was his illegitimate son, who Heihachi is unaware of, planning to kill him because Lars knows what the evil reputation Heihachi has. 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.
The original leader of the Mishima Zaibatsu, and the fighter known as the "King of the Iron Fist."
Heihachi continues to fight for control of the Mishima Zaibatsu against his son, Kazuya, and his grandson, Jin.
After having recovered from the injuries he sustained in the suicide attack on him from the G Corporation's Jack units, Heihachi is back with an iron fist--and body to match.
Heihachi is first seen in a flashback while fighting Kazuya as a child after murdering his wife, Kazumi. Heihachi easily knocked out Kazuya, and later threw his son off a cliff.
After Jin's presumable disappearance through supposed sacrifice of destroying Azazel, Heihachi infiltrates the Mishima Zaibatsu and defeats many Tekken Force soldiers. He then fights and defeats Nina, forcing her and the Tekken Force to work for him with his claim that he alone can restore the Mishima Zaibatsu to its former glory. Heihachi then launches a worldwide broadcast of his return and the announcement of the King of Iron Fist Tournament 7, with the intention of exposing Kazuya's devil form to the world.
His next step is to fly to the Archers of Sirius main base to get the organization on his side, despite their refusals in the past. After he and Nina dispose of several exorcists, Heihachi battles and defeats their leader Claudio Serafino, telling him that they are working for the same goal of bringing down the devil.
Later, Heihachi launches a worldwide search for Jin to use him to expose the devil to the world. But he then learns that his illegitimate son, Lars, has rescued Jin in the Middle East and is hiding him. After the Tekken Force fails to capture Jin, Alisa, and Lee, Heihachi warns Nina that he does not give second chances, prompting her to apprehend Jin herself.
Meditating at the Mishima dojo, Heihachi is suddenly attacked by an unknown assailant, who simply calls himself as "someone whose fists know no equal." The two of them battle, but their fight is interrupted by an army of Jack-6 sent by his son Kazuya to kill him. They form a temporary truce and take out the robots. Afterwards, Heihachi learns that his opponent's name is Akuma, and that he is repaying a debt to Kazumi by targeting both Heihachi and Kazuya. Startled by this revelation, Heihachi battles Akuma again but ultimately loses the fight and is seemingly killed by his assailant.
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.
In an unknown location, Heihachi meets with an investigative journalist who was looking into the Mishima Zaibatsu. Impressed on all that the journalist had already found, Heihachi decides to tell him about the dark secrets of the Mishima family.
Many years ago, Kazumi had arrived at Jinpachi's dojo when she was only a child, becoming his son's rival in training. Heihachi found himself attracted to her and the two of them fell in love. In time, Kazuya was born, and both parents were filled with joy. But all of this happiness soon faded away when Kazumi developed a fever one day. While Heihachi was nursing his wife back to health, Kazumi suddenly got up and attacked him. The following day, her fever subsided and she had no recollection of what she had done to Heihachi. As this continued on, Heihachi simply dismissed it as her having a split personality. But on one stormy night, while training at the dojo, he was confronted by his wife, who claimed that he would one day become a threat to the world. During the battle, Heihachi learned from Kazumi that she married into the Mishima family for the sole purpose of killing him on behalf of the Hachijo family. Despite her transformation into a devil, Heihachi defeated and seemingly killed Kazumi. When he turned to leave, he was attacked again by her devil form but he held her up by the neck. As she pleaded for her life, Heihachi noticed it's a trap, and shouted that she was no longer the Kazumi that he loved and snapped her neck. Letting go, Heihachi looked down on the corpse of his wife and shed one single tear. Because of the Hachijo clan's sudden betrayal and their evil nature, Heihachi becomes too paranoid for the rest of his tragic life as of the present.
After telling the journalist of Kazumi's death, Heihachi reveals that he threw Kazuya off a cliff to see if his son was not human, since he had his mother's cursed blood. Regretting not killing Kazuya when he had the chance, Heihachi decides that it is time to expose the truth of the devil to the world and be judged. Taunting the journalist by claiming responsibility for the deaths of his family, Heihachi reveals that he knew all along that the journalist had joined forces with Lars and had him taken away. He then had the Zaibatsu call his illegitimate son to pick up the journalist.
A few hours later, Heihachi confronts Kazuya for the final time at the mouth of a volcano. After a long exchange of blows at each other, Heihachi ends up fighting his son who transforms into the devil and loses. But even after being defeated, Heihachi musters all of his remaining strength and fights Kazuya again, who reverts back into his human form. Even though the two of them are worn out from the fight, they continue to exchange blows with one another until Kazuya delivers a fatal blow to Heihachi in the chest, killing his father once and for all. Heihachi's corpse is then tossed into a river of magma by Kazuya.
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.
Heihachi Mishima is a playable character in the PlayStation 2 version of Soulcalibur 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.
Playstation All-Stars Battle Royale
Heihachi Mishima is a playable character in the PS3 crossover game "Playstation All-Stars Battle Royale". He can summon Kuma during the battle or chain the opponents in a rocket like in the Tekken 5 ending for his Level 3 Super.
Heihachi Mishima is a playable character in Tekken Card Tournament. He functions as the game's "premium" character, since he has the unique ability to enforce or cancel out his opponent's actions. He can also heal himself when the cards that are designated to come into play. He can force his opponent to block, not strike, focus, or can't block, making matches against him terrifying. He can also take HP max from his opponent, and can deal powerful blows, but his drawbacks is that some of these cards enforce or cancel out his own actions, leading to inconvenient situations, and major disadvantages, especially since the other fighters all have specific cards that can be used to take advantage of his abilities. Overall, he is recommended for expert players, and for players that won't mind paying money for his additional cards, since as a premium character, his cards cost alot more than the standard characters. Matchups against him are never really seen, as there aren't alot of players who actually play as him online.
- Heihachi is a playable character in Namco X Capcom.

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.
Heihachi fights using Mishima Style Fighting Karate. His style is similar to Gojuryu Karate.

Note: Namco's translation is not the literal translation.
The only person Heihachi fears the most of all is his own son. There was once a time where Heihachi loved his son and had expected great skill from him since he was a child. He knew Kazuya had potential, yet was frail and lacked the determination need to hone his fighting ability. When Kazumi become completely infected by the Devil Gene and attacked Heihachi, which forced him to kill her. After Kazuya discovered this, the once kind boy started to be a bitter and hateful child who sought revenge against his father after what had happened to his mother.
Due to Heihachi's guilt of losing his wife and his son's inability to forgive him, he tossed his son down a deep ravine, suspecting that Kazumi's evil blood would help him survive the fall. As he expected, Kazuya had awakened the Devil Gene inside of him, which enabled him to climb back up. After this, Heihachi saw the error of his ways and realized what kind of monster his son truly had become. Despite this, as Heihachi grew old, he wanted the power of the Devil Gene to gain eternal life in order to gain equal footing to defeat Kazuya.
In the events of Tekken 7, Heihachi manages to regain the Zaibatsu due to his grandson's disappearance after he sacrifices himself to destroy Azazel. He quickly strengthened the Zaibatsu before Kazuya takes over. His main strategy to defeat his son and to hold another King of Iron Fist Tournament. Despite his initial goal to gain eternal life, when he faced Kazuya for the last time, he used his natural strength to fight him and faced his end with dignity.
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 with 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 end 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 left that 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. 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 Soulcalibur II (PS2), Heihachi even mentioned Kuma at the end of his fight with Inferno saying "Even Kuma is stronger than you."
Unlike Kazuya, Heihachi seems to respect and admire Lars for his fighting ability and uniqueness to his half-brother as well as being a better man than Kazuya. 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. Due to Lars already knows his father's inner status on causing a betrayal and an endless fight within a family line, starting with Kazuya, then Jin, Lars has a grudge against him and never trusted him from the beginning. Planning to kill him at first, however, Lars spares him later while jokingly that he should join a circus of having a fitting body at his age instead, yet swore to defeat him for justice if he does something bad ever again.
- 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 during his final battle against Heihachi that he killed Kazumi for unknown reasons. In reality, Heihachi does regret killing Kazumi, as he shed a tear for her after the sudden downfall of her clan and herself into killing Heihachi, which is the reason why he didn't spill the further truth to his son about Kazumi and her clan's true nature that results in him into becoming a paranoid man. Unknown to him after Kazumi is "healed" from her "unknown sickness", was that Kazumi made a deal with Akuma (whom was indebted to her for rescuing him from an unknown situation) to kill Heihachi as well as Kazuya if she dies.

- Nina Williams - He was her assassination target during the first tournament. Forced work for him during the seventh tournament, but managed to defect and escape from his watch once she found out Lars have a right reason to keep Jin under his protection.
- Ling Xiaoyu - Promised her that he would build her an amusement park if she won The King of Iron Fist Tournament 3. Unfortunately, as of the fourth tournament ends, he appears to attempt to use her as a bait to lure Jin out, but Yoshimitsu managed to rescue her giving the same warning Jin warned about Zaibatsu's true color.
