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 main protagonist and anti-villain of the second game, he is the main antagonist 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 as he has become a minor character to the storyline. But in Tekken 7, Heihachi is part of the main storyline once again and is also the main antagonist of the game. It was confirmed that he was not the one who started the Mishima feud in the first place, as it was his wife, Kazumi Mishima who started it all. Heihachi is the son of Jinpachi Mishima, the ex-husband of Kazumi Mishima, the father of Kazuya Mishima and Lars Alexandersson, the adoptive father of Lee Chaolan, and the grandfather of Jin Kazama.
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 (if the player uses him, his final boss would be his son) 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, paternal 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 an elderly, yet, buff man. He is shown to have grey hair with a distinctive hairstyle across all the Tekken series. (With some exceptions in: Tekken 1, Tekken Tag Tournament 2, and Tekken 7 with its flashbacks and character customization.) With his legacy outfit, he wears a black sleeve-less karate gi outfit with a tiger head design on the back. In Tekken 7, he had a new attire which looks like a samurai-like design.
Character Profile: "Heihachi 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."
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.
Like all boss and sub-boss characters in this game, Heihachi does not have an ending movie.
Version 1: Heihachi, beaten by Kazuya in the last tournament, instantly lost his dignity and fortune.
Grief-stricken over his past transgressions and for neglecting his studies drove Heihachi to a life of seclusion deep within the mountains with his dear friend, Kuma, where he refined his Mishima Combat Karate.
Heihachi descended from the mountains after catching wind of Kazuya's new Tekken tournament with the intentions to participate.
Version 2 (Manual): 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 3: 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..."
Tekken 5Head 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. Jinpachi awakens and wonders where he is, he tries to move but finds out he is strapped onto the rocket with chains by his wrists and ankles unable to move, Jinpachi desperately tries to break free but to no avail cannot seem to, it is then revealed Kazuya is also strapped to the rocket just like Jinpachi and cannot break free and finally Jin is revealed to be strapped, also unable to break free. As the countdown gets to ten seconds left. They all try to get free desperately and fast using but unable to break themselves free, as the countdown reaches five Kazuya realised his grandfather is also strapped and calls out to him, Jinpachi then hears Kazuya and realises that he and his grandson plus great-grandson are all strapped. After the countdown is over, a female voice says, "Ignition!" The rocket is launched and all of them have failed to break free and they all scream. Heihachi looks at their faces with binoculars revealing them possibly bracing themselves 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.
In the Scenario Campaign, he is a boss at Mishima Estate. Lars and Alisa are led to him by Tougou, who tells Lars that he was planning to meet him before his amnesia. On their way there, they meet Wang who tells them to ask Heihachi about an epitaph he found in Central America, as Wang believes it might reveal what the Zaibatsu is planning to do next. At the estate, he is guarded by his personal security force called "Secret Service" that partly consists of former Tekken Force members. It is revealed that Heihachi has been following the rebel leader Lars for some time, and is impressed by his fighting capability and plans to have Lars join him. When Lars and Alisa reach him, they proceed to fight and defeat him, leading him to ponder how someone like Lars could match his fighting ability so well. They then have a conversation where Heihachi finally realizes that Lars is his illegitimate son, with Heihachi stating how he "always had [his] suspicions" (indeed, in Tekken 7, it is revealed that Heihachi knew of Lars being born). Lars then threatens his father at gunpoint and asks him where the epitaph is, leading to him realizing that Wang had helped them. He does not budge, however, and the situation gets more tense. After dispatching a few more of his guards, Lars is finally able to get a clear shot at his father and shoots him despite Alisa's objections. However, Heihachi manages to catch the bullet with his teeth, and spits it away, saying how a tiny "peashooter" like that can't hurt him. Lars then mocks him and tells him to join a circus, before getting a call from Tougou who informs him that the location of the epitaph has been found. Lars and Alisa then leave him be but not before Lars vows that his will be the last face Heihachi will ever see. When a guard then asks if they should let them go, Heihachi says not to bother since "in the end they will all be [his]" and laughs.
Heihachi is not seen in the story after this and the mysterious epitaph is never mentioned again either. It's likely that the epitaph was just something related to Ogre, and thus unrelated to Azazel, as it was stated to be found by Heihachi and related to a Tekken Force unit being wiped out while exploring ruins in Central America "a while ago", fitting Ogre's backstory.
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 presumed 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, which has fallen to earth and caused devastation.
In an unknown location, Heihachi meets with an investigative journalist who was looking into the Mishima Zaibatsu. Impressed by 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 was 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 seems to have become paranoid for the rest of his life.
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. He has the journalist away, then has 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 final blow to Heihachi in the chest, defeating his father once and for all. Heihachi's body 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.
Although Heihachi dosen't appear as a playable character the bowling pins are based on him.
Heihachi returned as a playable character for Tekken Tag Tournament.
For more information, see Heihachi on the Soulcalibur wiki.
Heihachi Mishima is a playable character in the PlayStation 2 version of SoulCalibur II. His appearance is exclusive to this release, as Nintendo's Link (The Legend of Zelda) is exclusive to the GameCube release, and Spawn is exclusive to the Xbox release. He appears in the HD remastered versions of the game for PlayStation 3 and Xbox 360 as well, along with Spawn.
Heihachi's story aligns him with evil and the Soul Edge sword, but his motivations are his own. He simply wants to challenge the best in the realm, and leaves once he has accomplished his goal. His weapons include various forearm guards and knuckles, being the only true pugilist in the game. His ultimate weapon, Tekken, references the series and that he prefers to fight bare-handed.
This appearance also marks one of only a handful of occasions in which Heihachi received an English voice dub.
Heihachi appears in Nina's 2005 spin-off game, Death by Degrees. In the game, he is first seen in the projector room where Enrique Ortega is speaking with him (in Japanese) about the Tekken Force soldiers he hired Heihachi to protect himself. While they're still communicating with each other, Nina Williams drops from a balcony and lands catching Heihachi's attention on her, wishing for himself to take her on. As for Enrique fights Nina off with a katana sword, although he ultimately gets beaten by her. Later on, towards the end of the game, Nina will either fight her sister or Heihachi Mishima as the final boss if the player beats Anna Mode.
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.Daisuke Gōri, had died in January 2010, and the Tekken Tag games are non-canonical, Heihachi was given a rejuvenated appearance in this game to better suit his new voice actor, Unshō Ishizuka. Heihachi's new voice actor and appearance were announced on Twitter by Katsuhiro Harada on December 23, 2010.
To better explain his changed appearance in-game, Heihachi was also given a backstory on the official page:
"Working as the long-time head of the Mishima Zaibatsu, Heihachi Mishima solidified the organization’s foundation. At the same time, however, he ran a top-secret research lab, on the search for a way to understand the aging process and regain his youth. The search for perpetual youth and longevity may have seemed like just a dream, but after years of work, his team of researchers finally completed the rejuvenation serum he sought. 'Ha ha ha... Now, eternal youth is finally within my grasp!' Gulping down the serum, the effects became to emerge almost immediately. Within minutes, he had transformed into a younger version of himself, complete with a full head of black hair. 'This surging power...! Now I will be invincible!' Just as Heihachi was musing over how to reveal his newfound power to the world, the Tag Tournament announced its opening. 'Tag, huh? I think I know just who to choose as my partner.' And with that, the curtain raises on the mysterious Tag Tournament."Heihachi on the PlayStation All-Stars Battle Royale Wiki & Heihachi's movelist
Heihachi Mishima appeared as a playable character in the 2012 PS3 crossover game "PlayStation All-Stars Battle Royale". His appearance was based on his rejuvenated look from Tekken Tag Tournament 2.
Like all characters in this game, he has three levels of Super Moves: his Level 1 Super is a faster version of his Lightning Hammer (d+1+4) unblockable that also emits a small lighting upwards, his Level 2 Super summons an AI-controlled Kuma II to aid him for a while, and his Level 3 Super chains the opponents onto a rocket and sends them off to space like he does to his family in his Tekken 5 ending.
Heihachi's unlockable alternate costume is his fundoshi from Tekken 4 which also features him in his normal older appearance, and his DLC costume is his fur-collared coat from Tekken 3.
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 has made a few cameo guest appearances in Nintendo's cross-over series, Super Smash Bros., the latest two installments of which have also been partly developed by Bandai Namco.Mii Brawler character; resembling his rejuvenated self from Tekken Tag Tournament 2. His Mii personification also sports a quick appearance at the end of Ryu's reveal trailer for Super Smash Bros. 4, where he engages Ryu in a fight. Heihachi was also briefly considered to be the crossover representative for Bandai Namco in Smash Bros., but was later dropped from the roster in favor of Pac-Man.
King of Fighters: All Star
Heihachi is set to appear at SNK's mobile game alongside Kazuya and Jin as Tekken's guest characters.
Heihachi has had several other guest appearances outside the Tekken universe:
- Heihachi is a playable character in Namco X Capcom.
- Heihachi makes a cameo playable appearance in Pac-Man Fever.
- Heihachi appears as a solo unit in the collaborative crossover titles, Project X Zone and Project X Zone 2.
- Heihachi is playable in the crossover game Street Fighter X Tekken.
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.
The person Heihachi hates 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 needed to hone his fighting ability. When Heihachi's wife, Kazumi became completely possessed by the Devil Gene and attacked Heihachi, he was forced 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 over losing his wife and his son's inability to forgive him, he tossed his son down a deep ravine, suspecting that Kazumi's devil blood would help him survive the fall. As he expected, Kazuya's Devil Gene was awakened inside of him due to the near-death experience, and this gene enabled him to climb back up. After this, Heihachi raised Kazuya and adopted a son to be his rival so that he could hone his fighting skills against him. As Heihachi grew old, he wanted the power of the Devil Gene to gain eternal life in order to keep equal footing and defeat Kazuya.
In the events of Tekken 7, Heihachi manages to regain the Zaibatsu due to his grandson's disappearance and announces the next King of Iron Fist Tournament in order to use it as the perfect stage to reveal to the world that Kazuya is a Devil. He does this so that he can turn public opinion against Kazuya in the global war for world domination between the Mishima Zaibatsu and G Corporation. 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.
In Tekken Tag Tournament when paired with Lee, Heihachi will sometimes give him a noogie or spank him, showing that he still treats him like a child and is happy to humiliate him. Lee felt no respect for Heihachi as seen in his endings each showing he is trying to either beat up, kill or even humiliate Heihachi.
Heihachi's grandson. After Jun Kazama disappeared, Jin sought out his grandfather Heihachi under her instructions. He took Jin under his wing and trained him in the Mishima style to fight Ogre. Heihachi 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, participating with Jin in the tournament.
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, being kind to his grandson. Jin liked a lot and looked up to his grandfather, trusting him with his life.
It is unclear how much Heihachi ever cared for Jin however, since it became clear that Heihachi was using Jin and the tournament to lure Ogre out so that Heihachi could gain samples from the creature that would make himself more powerful. As soon as Heihachi no longer needed Jin to bait Ogre, he used Tekken Force to capture him, and then shot Jin in the head. This caused Jin's Devil Gene to activate, something Heihachi may have suspected would happen, given that he knew the genetic nature of the devil gene. After Heihachi's betrayal, Jin lost all respect for his grandfather and started to despise everything about his bloodline.
Heihachi's father. It is unknown how was their relationship prior to Heihachi's betrayal, but Jinpachi was the one that trained Heihachi in the Mishima style Karate (and also trained Kazuya). About 50 years before Tekken 5's events, Heihachi defeated Jinpachi and took the Mishima Zaibatsu from him, and when Heihachi attempted to make the Zaibatsu enter the military industry, Jinpachi tried to stop him, only to be defeated and locked under the Hon-Maru, causing him to starve to death. After his betrayal, Jinpachi held a deep dislike for his son and wanted to bring him to justice, but from his Tekken 5 dialogue, Jinpachi still cared about him and regrets the feud that the Mishima family was brought in. Heihachi on the other hand, didn't like his father and forgot that he locked him under Hon-Maru.
One of the only "people" 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 mentions 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 Scandinavia. Due to Lars already knowing his father's status of causing betrayal and endless fighting within the family line, starting with Kazuya, then Jin, Lars has a grudge against him and never trusted him from the beginning. During this meeting, Lars tried to shoot Heihachi, but Heihachi managed to stop the bullet with his teeth. Lars then jeered that he should join a circus, but spared him due to Alisa's insistence, yet swore that he will defeat him for justice if he does something bad ever again.
- Kazumi Mishima - His beloved wife. She was the only Mishima family member who he never hated and one of the only people Heihachi ever cared about other than himself. He was forced to kill her after her Devil side caused her to take action and try to kill Heihachi after he had overthrown his father.
- Doctor Abel - Abel worked for Heihachi and the Mishima Zaibatsu as a scientific adviser in Tekken 4, before apparently being killed by Bryan Fury.
- Michelle Chang - He stole her amulet and used it to resurrect Ogre. 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 sought to capture it in the hope of creating the ultimate life form in Tekken 3. Later, in Tekken 4, Heihachi's scientists tried to use captured samples of Ogre's blood and tissue in order to splice Ogre's DNA with Heihachi's and make him immortal, but the experiment failed since Heihachi lacked the necessary Devil Gene in his blood.
- Nina Williams - He was her assassination target during the first tournament. Heihachi later employed her in Tekken 7.
- Ling Xiaoyu - After Heihachi discovered her to have singlehandedly defeated multiple of Heihachi's men after being found trespassing on a Mishima Zaibatsu yacht, Heihachi was greatly amused, let her go, and promised her that he would fulfill her dream of building her own personal amusement park if she'd win The King of Iron Fist Tournament 3.
- Violet - The alter-ego of his adopted son.
- Panda - Heihachi trained her as a gift to Xiaoyu.
- Mr. Rochefort - Seems to be one of his business partners.
- 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.
- Steve Fox - Heihachi ordered his creation to get himself a more durable test subject for his Devil Gene research after the second tournament. Steve survived and later escaped, and, due to this, in Steve's TK4 ending and in Street Fighter X Tekken, Heihachi can be seen expressing a desire to eliminate Steve, likely due to fears that Steve might tarnish the Mishima Zaibatsu's reputation if the full truth of his past ever came to light.
- Yoshimitsu - Heihachi was robbed by him and his clan during Tekken 4.
- Prototype Jack - Heihachi entered him in the first King of Iron Fist Tournament to defeat his rival and upgrade, Jack.
- Akuma - Sent by his estranged ex-wife Kazumi (whom he owed a debt to for saving his life from an unknown situation), to kill Heihachi & Kazuya should Kazumi fail to stop them. They first met when Heihachi was meditating at the Mishima Dojo. Akuma stated that the reason he did not appear until now was due to him "only waiting for [Heihachi and Kazuya] to get stronger". They began to fight, but the fight got momentarily interrupted by Jack-6 robots. After the robots were defeated, they continued their fight, leading to Akuma ultimately defeating and nearly killing Heihachi.
- Claudio Serafino - Heihachi tried to recruit Claudio's group of exorcists in Tekken 7 in order to better fare against Jin and Kazuya's devil powers, but the group refused to voluntarily aid him, leading to Heihachi personally visiting them and "persuading" Claudio to join him.
- Geese Howard - Possible Rival CEO. In Geese's reveal trailer, he deems Heihachi too weak to control the world and says that he "can just die".
- Heihachi Mishima is one of the four Tekken characters that have appeared in all of the Tekken games (the others being Nina Williams, Paul Phoenix and Yoshimitsu).
- His given name in Japanese is 平八 which is literally "flat eight" in English. All Mishima given names end with the kanji "八" (meaning "eight"). It can be read as hachi, hatsu, ya, yattsu or yō. The surname of all members of the Mishima family 三島 (Mishima) means "third island".
- Heihachi's fighting style is heavily based on Okinawan karate styles such as Shorin-ryu and Goju-ryu.
- Leroy blames Heihachi for the violence that the Mishima Zaibatsu did to his family in New York 50 years ago, even though Jinpachi was head of the Zaibatsu at this time. It is likely therefore that Heihachi had significant power in the Zaibatsu under his father's leadership and that he may have used this power to terrorise others and cause violence, despite Jinpachi's pacifist intentions for the Zaibatsu at this time.
- Heihachi was voiced by Daisuke Gōri prior to his death on January 17, 2010, from Tekken 3 to Tekken 6, by Banjo Ginga in Tekken and Wataru Takagi in Tekken 2. From Tekken Tag Tournament 2 until Tekken 7, he was voiced by Unshō Ishizuka.
- He is also one of the bonus characters available to play as or against in Anna Kournikova's Smash Court Tennis for the PlayStation, alongside fellow Namco characters, including Tekken characters Eddy Gordo and Yoshimitsu (in his Tekken 3 incarnation). Heihachi also appears as a playable character in the PlayStation 2 version of Soulcalibur II.
- In the PlayStation 2 version of Soulcalibur II, the player can choose to change the voice languages to either English or Japanese. If Japanese is chosen, he is voiced by Daisuke Gōri. If English is chosen, he will have the English voice actor Kevin Michael Richardson (who went under the alias Victor Stone). His "Destined Battle" is against Raphael.
- The tiger's head design at the back of Heihachi's karate gi primary outfit could be for the memory of his wife, Kazumi who also had a pet tiger.

- Heihachi (and Kuma II) are able to face Japanese PlayStation mascots Toro and Kuro, and Cole MacGrath from the inFAMOUS series in two entirely different games: Street Fighter X Tekken and Playstation All-Stars Battle Royale. Additionally, if Heihachi's Mii Costume from Super Smash Bros. 4 is counted as Heihachi, he is also able to face Pac-Man, Mega-Man, and Ryu in both SFxTK and SSB4.
- In the long, "New Content Approaching", trailer for Super Smash Bros. for 3DS & Wii U on June 14, 2015, where Ryu and Heihachi's Mii Costume were first revealed, the part where Heihachi is showcased is accompanied by the character select theme from Tekken 6. Said music was also used for the introductions in the Tekken 6 character trailers for each character.

- His sub-boss is Lee Chaolan.
- He is the protagonist of the game.
- Heihachi bizarrely speaks mostly in third person.
- His reason for throwing Kazuya down a cliff is better explained (Heihachi states that lions push their cubs off cliffs and raise only those who climb back up). Whilst this version of the story fits with the earlier Tekken games, since the introduction of the devil gene into the Tekken canon, this is no longer Heihachi's primary motivation for throwing Kazuya off.
- Heihachi also seems have a greater sense of honour in the movie, stating that if Kazuya did not survive the fall from the cliff, then Heihachi would have killed himself. Heihachi also rebukes Lee for caring only about power and wealth rather than understanding the honour and spirit of fighting.

- Heihachi is unlocked by beating Story mode 9 times with different characters.
- His win animation, "Come back when you're ready to fight!" (when holding the square  button, he says this while picking up his defeated opponent by the head, and then slamming their face into the ground), works on all characters except Yoshimitsu.
- If the penultimate round in the "Time Attack" mode is reached fast enough, a sub-boss fight with Heihachi can be triggered. He has a brief cutscene with varying dialogue before the fight;in one of them, Heihachi introduces himself as "The true leader of the Mishima Zaibatsu".

- Heihachi's first two opponents in the "Arena" mode are Jack-6 and Kazuya Mishima.
- Heihachi can be customized to look like Jiraiya "The Pervy Sage" from the Naruto series, Raiden from the Mortal Kombat series, & Akuma.

- He is a minor antagonist in the game's story mode.
- He is the final boss in Jin's "Arena" mode.

- His official partner is Kuma II.
- Their special intro has Heihachi preparing for battle and calling Kuma, before suddenly looking and pointing at Kuma confusedly due to the latter having imitated his movements.

- Akuma's swap costume has him don Heihachi's infamous fundoshi from Tekken 4 as well as his signature hairstyle.
- In his rival battle with Guile and Abel, Heihachi notes Guile's peculiar similarities to Paul due to Guile's hairstyle. However, in one of the victory screen dialogues during the arcade run, Heihachi shows Kuma a picture of the two men and tells Kuma to remember them, so it seems that Heihachi and Kuma "recognizing" Guile is meant to have a double meaning. However, neither of them still manage to fully recognize or remember who they are.
- Heihachi is the only character who does not get possessed by Pandora when using it during a match, he instead gets angry and his skin becomes red (the power-up effect remains the same as the regular Pandora).
- This is one of the few interventions by Namco on the game, as stated by Harada that Heihachi does not accept any kind of help or transformations.
- Three of his themes from the Tekken series were remixed for the Mishima Estate stage, making him the only Tekken character in the game outside of the boss characters (Jin, Xiaoyu, Ogre) to have their theme or themes be remixed.
- Heihachi's up+circle move is called the "Bowling Pin Toss"; it has Heihachi throw a Heihachi Trophy in an upwards arc that will deal damage to the first enemy it hits. The move also has a chance of him spawning and serving a Tekken Ball, which all players can then use to deal damage by striking it into enemies, just like in the Tekken Ball mode in Tekken 3. Said move is also Heihachi's only ranged ability, fitting his status as a martial artist.

- Heihachi has two CGI appearances which are his normal CGI art his CGI art as a special boss.
- He is the penultimate boss in the arcade mode and can be replaced with Jin.
- He along with Kazuya are the main protagonists of the game.
- Heihachi's Tekken Tag Tournament 2 design (his younger self), is seen in flashbacks in Story Mode. He can also be customized to look like his younger self, but he will still have wrinkles on his face.
- He can be customized to resemble old Joseph Joestar from JoJo's Bizarre Adventure, with whom Heihachi shares a voice actor.
- Unlike most other rage drives that send the opponent to the ground and guarantee ground hits, which are middle and single hit, and launch standing opponents, Heihachi's rage drive (b+2,1+2) is a two-hit middle, high move that bounds standing opponents. Also, it is not possible to make the 2nd hit do 60% damage on the wall due to it being a high.
- In his Rage Art, he launches the enemy with his old Twin Pistons (d/f+1,2) from before Tekken 6 (where it was changed into a bound move).
- Additionally, he also regains the use of the Twin Pistons during the final chapter of The Mishima Saga and when he is encountered as a special boss in Treasure Battle.
