Heihachi Mishima

==Early Life==
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. Although the son of a martial arts master, Heihachi was not taught his father's famed Mishima Karate, as Jinpachi wished for his son to have a more, educated life, working as the eventual successor to the Mishima Zaibatsu. The young Heihachi and his childhood best-friend, Takuma Sakazaki attended Kangokou High, which showed the young boys how hard life can be, by the time of their sophomore year, they were a constant target of Kangokou's numerous bullies who beat them up routinely after school. However unlike Takuma, Heihachi is far more quick tempered and less willing to take the beatings lying down. When Heihachi informs his father how much he not only wants but also needs to learn Mishima Karate, Jinpachi shrugs this off telling his son that anybody can be bought with money and suggest to flash some at the attackers, which only results in Heihachi and Takuma getting beaten up more. 
==Osu!!! Karate Bu ==
As the pair grow increasingly tired of being victimized they decide to join the Karate Bu Karate Club, which is notorious throughout Osaka's youth gangs for training and producing the city's most hardened and toughest teenage thugs while maintaining the facade of a legit school sports club. But when they join the club, they find themselves picked on just as much if not worse by the club's current members. But as their training progresses they grow to be increasingly capable fighters. However things would eventually take a turn for the worse for Heihachi when an old junior high classmate of his named Yamane Junji reveals to him that he's joined the Yakuza, and forcibly steals the Karate Club's money from him at gun point. Heihachi felling as if he has dishonored the Karate Club quits the team, but to the disappointment of Takuma. After hearing what happened with the Yakuza member Jinpachi became traumatized at the thought of losing his son and decided to finally teach Heihachi to properly defend himself. Jinpachi then taught his son Mishima Style Fighting Karate (三島流喧嘩空手 Mishima-ryū Kenka Karate) including the deadly moves "Rising Uppercut", "Dragon Uppercut", "Tsunami Kick", "Flash Punch Combo", "Demon Slayer", "Spinning Demon", and "Demon Scissors". During the middle of junior year Heihachi purposely encountered Yamane, braking four bones in his body and retriving the exact amount of money that Yamane took from him last year. Takuma surprised at the dramatic increase in Heihachi's abilities asked Heihachi if he could also learn Mishima Style Fighting Karate, even going so far as to beg Jinpachi until till he finally agreed. 
==Life in Prison==
The boys seemed to have a bright fighting future ahead of them, however the gang life consumed Heihachi, during his senior year, resulting in him killing another rival gang member and leader of all the waring gangs, Imawara "Kira" Takashi, with his bear hands. Because of Jinpachi's expensive lawyers Heihachi only got a 10 year sentence to prison. Takuma and Heihachi's mother went to visit Heihachi everyday something Jinpachi rarely did seeing his son as an embarrassment. Heihachi would grow an increasing resentment for his father because of this.  
While in prison Heihachi did nothing but practice his craft perfecting Mishima Style Karate into a deadly Martial arts, in a place it had acquired it's origins. It was also in prison that Heihachi began to condone the weak, growing increasingly frustrated that people were subjected to harassment and physical abuse, by other inmates, and began braking the bones of both the attacker and the victim earning him the nickname Tora o funsai-bone literally meaning “Bone Crushing Tiger”. This resulted in a feud between himself and several Yakuza members inside the prison walls. Heihachi defeated and broke so many of the members that they had to force Heihachi into solidtary confinement until he served his remaining sentence. 
==Struggles On The Outside==
Once out he was welcomed back by Takuma and his mother but merely greeted by his father, who refused to give Heihachi anymore money or shelter until he found an honest job. Hehiachi then moves out of his family's estate of Hon-Maru, and for the next several several months goes looking for an earnest job while working part time at Takuma's dojo in order to pay the rent on his apartment. As the struggle grows more and more apparent for a 28 year old convict times get even worse for Heihachi as Takuma's dojo expands across Japan forcing Takuma to leave Osaka and move to Tokyo, in order to promote his business on a larger scale. However with Takuma gone and struggling to get his new dojo started, the old one now being fully run by Heihachi folds. 
==The Street Fighter==
Because of this Takuma and Heihachi head down completely separate paths Takuma eventually becomes a nationally known Dojo owner across Japan; Heihachi, decides to uses his deadly arts to his advantage, becoming a mercenary, and assassin, living only to prove his own fighting abilities. Heihachi has little in the way of a moral code, and will resort to any means necessary to collect on debts owed to him, including selling his debtors' family into sexual slavery. Such as when he meets the condemned murderer Tateki (Junjo) Shikenbaru while disguised as a Buddhist monk. Heihachi applies his "oxygen coma punch" to Junjo, causing him to collapse just before he can be executed. As Junjo is rushed to a hospital, Heihachi and his sidekick Rakuda (Ratnose) ambush the ambulance and free him. As Heihachi and Ratnose watch the incident on the news, Junjo's brother Gijun and sister Nachi arrive and plead for more time to pay for Heihachi's help. Outraged, Heihachi refuses and attacks the siblings. Gijun accidentally kills himself when Heihachi dodges his flying kick, causing him to go out of a window, and Nachi is sold into sexual slavery through Renzo Mutaguchi. Mutaguchi and his associates attempt to hire Heihachi to kidnap Kazumi Sakazaki, the younger sister of Takuma whom Heihachi never met due to her going to an all girl boarding school in china during their youth. Heihachi is asked to take Kazumi because her father, an oil tycoon “accidentally” dies. Heihachi refuses after discovering that the gangsters are Yakuza and that would result in condemning his best friends sister. He escapes, but the Yakuza gangsters resolve to kill Heihachi as well as kidnap Kazumi. Heihachi immediately seeks out Kazumi, who is being protected at the Nippon Seibukan dojo by her uncle, Kendō Masaoka, a Karate master. Heihachi captures Kazumi and challenges the entire dojo to a fight. He brutalizes the rank-and-file students before Masaoka bests him. Ultimately, Heihachi offers to protect Kazumi, and Masaoka agrees, against Kazumi's protests. Meanwhile, the Yakuza's allies in Hong Kong, led by Kowloon boss Dinsau, recruit Junjo Shikenbaru to avenge his siblings by killing Heihachi. The gangsters make several attempts to kill Heihachi before they successfully kidnap Kazumi. Heihachi manages to rescue her, but gets captured himself. Ratnose gives up Kazumi's location to save Heihachi, causing Heihachi to forsake him. When Heihachi faces a blind swordsman working for the Hong Kong gangsters, Ratnose dies in a reckless attempt at redemption. Heihachi finally tracks the gangsters down to a shipyard and fights his way through their guards. In the end, Dinsau permits Heihachi to duel Junjo. Nachi sacrifices herself to give her brother a free shot with a sai, but Heihachi survives and kills Junjo. Critically wounded, Heihachi is helped to his feet by Kazumi and Dinsau, earning his respect. 
==Return of The Street Fighter==
Heihachi is then hired by Japanese mobster Otaguru Tanaka to kill a pair of captured employees so they cannot inform on his activities (he has teamed with the American mafia under the guise of building a martial arts center). When Otaguru orders Heihachi to kill his friend Master Masoaka, Heihachi refuses and is forced to go on the run with. To make matters worse, Junjo's bastard brother Tsugury, has appeared and set his sights on revenge. Heihachi takes a vicious beating from Tsugury, but recovers in time to punch, kick, and gouge his way through everyone who has crossed him, including Tsugury and the police force.
==The Street Fighter's Last Revenge==
Heihachi now 32 has been doing nothing but assassinating people for the last 4 years, he has become increasingly tired of all the blood soaked on his fist, and finds himself thinking more and more about Kazumi everyday. However he soon finds no time to ponder her as he quickly receives another assignment. Heihachi is tasked with retrieving Go Owada during a riot. Heihachi evacuates Go Owada in the middle of a violent strike in which bitter workers at the largest chemical manufacturing plant in the East are engaged in combat against a riot police squadron. After Heihachi receives what is believed to be payment for bringing Go to them, he discovers that he had been paid in newspapers. Outraged, Heihachi lashes out at the mobsters present and clashes with a young assistant district attorney from Taiwan named Huo Feng, that reminds him of Kazumi. The Owada family is enraged that Heihachi turned on them and decides to crush him. Upon returning from a shareholders' meeting at Tokyo Chemical, Seigan blackmails a politician, Mr. Iizuka, with a tape recording of a recent conversation just as Heihachi ambushes them and steals the tape. Aya is inspired to hire a former Mafioso from Chicago, Frankie Black, after watching him tear apart a strong chain on live television. Upon hearing who her new partner is, Huo Feng turns on the Owada family and decides to align herself with Heihachi. Meanwhile, Kunigami confronts Heihachi after Aya outwits him following a dance at the local club, and he nabs the missing tape after defeating him at the local fairgrounds. Afterward, Heihachi turns to Master Masaoka to learn some Okinawa styles of martial arts and reclaims the tape after intercepting Kunigami as he returns home. Heihachi later encounters Huo Feng after she intercepts him in a tunnel. Unknown to them, Frankie Black and his gang had shown up to ambush them, and Black kills Huo Feng before retrieving the money Heihachi had been paid for the blackmail tape. Kunigami then allies himself with Seigan to crush Heihachi, who chases after some of the Owada family's goons, disguised as a motorcycle cop, and fights them at a car crushing plant. Seigan sends Aya after the money, which Heihachi had hidden at Aoidani Funeral Home. She brings Black along to help with the retrieval. Heihachi intercepts them, having cleverly hidden himself inside one of the twin retorts behind a conveniently-placed casket, and burns Black to death in the ensuing struggle. Aya then proceeds to seduce him. Some time later, Go ambushes Heihachi, and the two fight, giving Aya enough time to escape with the suitcases. Realizing he had been tricked again, Heihachi follows Owada and his gang to a harbor as Kunigami confronts Seigan by himself, with Heihachi taking out many of the Owada goons and Kunigami taking on one goon and Seigan. Unknown to the survivors, Heihachi then puts a deadly surprise in the Owada family car. Aya is poisoned when Kunigami finds out she had tried to poison his drink, and Heihachi and Kunigami have a final fight to the death which Heihachi wins. Then a critically wounded Heihachi fails to save Aya from the booby trap he had placed earlier. 
==Going Global==
With the police still after him for the countless murders he has committed, Heihachi decides to flee all of Japan's cities and goes across the globe to not only continue his occupation but to also further train his fist. When he did this Heihachi's legend quickly grew from assassinating unwilling jobbers of the Sumo ring to murdering unwilling losers in the American sports of Boxing and professional wrestling; Killing a massive amount of Triads in china; outwitting the mafia in New York, and his most famed fight of all, decimating a wild tiger in India. Heihachi came to love his traveling life, although he still thought of Kazumi everyday.
==Mortal Kombat==
One day while traveling afoot in unoccupied land in Japan, he finds the oddest weather he has ever felt. It was strange as if a calm before a storm. In the middle of that night a strange thing accrued, the earth rumbled underneath Heihachi's sleeping body, and lighting began to strike all around them as rain poured down from the sky as if the gods them selves were crying. When Heihachi awoke, he finds the entire area shaking, known he isn't underneath steady ground, he begins to run, however Heihachi is not fast enough to out run fate and the ground crumbles underneath him. Then the unimaginable happened, a hole in the “bottom less pit of the world” appeared out of nowhere and Heihachi goes through it. As he lands sore from the fall he looks around at the gloomy place and says to himself, “So...This is Hell hun?...It's Not that bad”. However just then strange creatures/warriors rush out. Heihachi's pulse races as he looks at how strong the unknown creatures are and decides to challenge them to test his fists. As Heihachi battles he feels the overwhelming strength these warriors posses and gets invigorated as he begins to decimate them. Meanwhile the ferocious Heihachi cut by a being with long pointed teeth, large mouth, and blades protruding from his forearms. Heihachi becomes overwhelmed, but still manages to survive as his mysterious attackers leave without cause and without warning. Just as they leave, Heihachi tells the bladed creature that their fight isn't over and turns around to see a man standing behind him, eyes glowing. Heihachi steps back gets into stance and asks “And what creature are you” as he attempts to strike him. However the mysterious man merely sidesteps the attack, stating “I'll admit I’m impressed with your fighting ability but if you want a spot on my team, your going to have to do better than that.” Heihachi confused asks the man what he is going on about as he attempts another strike, but the man merely catches Heihachi's kick and gives a long sigh stating “I guess I was wrong about you, your not strong enough to save us” Heihachi is taken back by his words as he retorts “Save you ?..I'll kill you!” Raiden laughs and says “you don't get it do you, it's time, it's upon us” Heihachi deeply confused with the man and tired of trying to hit him, stops his attack and asks “What are you talking about” to which the man lifts his head up and his eyes emulate lightning as he says “Mortal Kombat”. Heihachi shocked asks “what are you” to which the man states “I am the Thunder God, Raiden, protector of Earthrealm...and I choose you to help me save it” Heihachi then says “what is this Mortal Kombat, why have I never heard of it ?” Raiden then says “Mortal Kombat is a tournament between the warriors of Earthrealm and those from outworld that wish to invade it...I choose you not for your personality, not for your lifestyle as you disgust me, but you have proven yourself to have vast skill in the arts of fighting and for that my team, Earthrealm, needs you.” Heihachi then asks “What the Hell is Outworld”. Radien laughs and says “we're in it as we speak” Heihachi is shocked and ask Raiden “so... we're not in Hell” Radien then jokes “Well that depends on your point of view” However Heihachi doesn’t laugh and simply looks at Raiden. Raiden then gets serious and tells Heihachi “Follow me”, curious to see if what this man is saying, is true Heihachi follows him. They meet with the other Kombatants for Earthrealm and Heihachi is introduced to the Chinese Monk twins, Sing and Sang who can combine themselves into one being named Siang, doubling their already formidable abilities. Heihachi finds pure amazement not knowing such a warrior existed or can even exist. Raiden then further explains to his team the severity of their need to win reminding most, but informing a few that in order to invade Earthrealm Outworld needs 10 consecutive wins in the tournament and already have 8. The next day the tournament begins, over the next week Heihachi and Siang are the only two the manage to make it to the finals on the side of Earthrealm, and Raiden chooses his first chosen warrior Siang to face the Mortal Kombat Champion, Prince Goro, a large creatures that dwarf Humans in size and boast incredible strength, possessing four massive arms complemented by three digits on each hand. Heihachi is horrified to see such a warrior but knows if anybody can defeat Goro Siang can. However the fused twins were defeated quickly by Goro who tore the warrior apart, in effect, tearing the two brothers out of their combined body. Sang dies from the forced separation and Goro decides to toy with Sing, ripping each limb off at a time. Heihachi seeing what awaited him if he competed sneaked away from the distracted Raiden and fled into Outworld. For 3 months Heihachi survives by himself in the uncharted world, immerses himself in the “live by your fist” culture of the realm, even getting his face painted like an Outworlder to signify his change. During his travels Heihachi defeats a Tarkatan and meets the walking wandering merchant, Maho Tsukai, offering the powerful Earthrealm warrior, a metallic claw. However something else catches Heihachi's interest a vile of liqud, at the bottom of Tsukai's cart. Tsukai smirks when Heihachi points the potion out, and calls it his most prized possession. Heihachi asks what it is and Maho tells him “The Blood of a thousand Immmortals (Edenians), to and the secret to Eternal Life” Heihachi is skeptical and tells Tsukai to prove him claims. Maho then takes out a sword from his cart, and “drinks” the elixir, merely holding the liquid in his mouth. Maho then stabs himself with the sword, spitting out blood along with the elixir. However Maho then secretly steals the fallen Tarkatan's soul, healing himself. Seeing the elixir work Heihachi buys it and immediately chugs the whole bottle exclaiming “I am Invincible!!!!”. Heihachi then continues his battle for survival in the apocalyptic world. Heihachi however unknowingly just put a countdown on his life as when he reaches 100 years old he will die automatically. Raiden eventually finds the adapted Heihachi and in disgust calls him a coward and forced him back to Earthrelm so he can see full hand the consequences of his cowardice actions, promising Heihachi that when outworld invades he will not save him.
==Building a New Life ==
When Heihachi resurfaces in Japan, he immediately heads to Tokyo to speak with Takuma. However Takuma is nowhere to be found and he instead finds Kazumi. The Two talk and she express gratitude for saving her again, to which Heihachi confesses his constant thought of her, she is flattered by his words and the two express more until Heihachi asks where he could find Takuma, she seems confused and asked “haven't you heard? Takuma is in America, he turned his dojo international.” Heihachi is saddened but brightens his day by spending the rest of it with Kazumi. The two continue this for months as they grow more and more love toward each other. Meanwhile with news that his missing son has surfaced Jinpachi sends for him. Jinpachi then attempts to repair their damaged father and son relationship which Heihachi pretends to accept, merely using his father for his influence, money and shelter. Heihachi is devastated to find that his mother died by suicide after his apparent death and he mourns her for a week. After that he then moves Kazumi into Hon-Maru and a month later she becomes pregnant. Heihachi's life seems to finally be on an upraise and he along with Kazumi go to America to ask Takuma permission to marry his sister. Takuma knowing what Heihachi as become over the years, looks into his eyes and sees something new, something terrifying, not the best friend he once knew. On that basis Takuma refused to bless his friend, resulting in the two having a falling out, much to the distraught of Kazumi. Heihachi and Kazumi then go through with the wedding and neither Takuma or his American wife Ronnet attend. 3 months later Kazumi dies giving birth to their son whom she names Kazuya right before her death. Heihachi then buries Kazumi next to his mother with Kazumi dying on his mother's birthday. Heihachi couldn't look at Kazuya, for several weeks as his look reminded him too much of his beloved wife and began drinking heavily, leaving Jinpachi and his servants to look after the infant. However Heihachi eventually sobers up and begins to take over parenting Kazuya. Heihachi raised Kazuya harshly. Much to Heihachi's chagrin, Kazuya grew up kind and frail, due to the more loving treatment he received from his grandfather. Heihachi told his father to stop being so soft to his son, telling him that the world was too hard for childish actions, and blames his father for his troubled childhood of being bullied. Heihachi dosen't however tell Jinpachi the true reason he pushed Kazuya from such a young age, Raiden's final words “you and your family will shout save me, and I will whisper...no”. Needing the Mishima bloodline to survive Kazuya must survive the invasion undoubtedly coming at some point. However even if Kauya wasn't up to par against the otherworlders he would have another plan, a fighting monster of his own, one that could defeat Goro. Heihachi needing the resources being head of Mishima Zibatsu provide betrayed Jinpachi and stole the Zaibatsu from him. 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, however Heihachi used this opportunity to “repay” his father for turning his back on him when he needed him most in life and defeated Jinpachi in one-on-one combat. Jinpachi was then sentenced to death via starvation by Heihachi as he imprisoned his father underneath Hon-Maru. 
==Training Kazuya==
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 the Devil Gene in his blood. To further motivate Kazuya, Heihachi adopted an orphan named Lee Chaolan and raised him as a rival to his true son. Heihachi didn't care about Lee at all and only used him to irritate Kazuya. Over the next 10 years, Kazuya finally found it too sickening to see his father's face and left the Mishima Estate, much to Heihachi's amusement. Heihachi further enjoyed the fact Kazuya fled to Takuma in America, not long after he found Lee to be of no purpose and sent him to America to irritate Kazuya. 7 years later however Heihachi forces Lee to the leave Southtown, and move to New York to handle the Mishima Zaibatsu's operations there, and to continue his business education. 
==King of Iron Fist==
Meanwhile Kazuya traveled abroad and competed in martial arts championships, becoming an undefeated champion. For the next 27 years Heihachi devotes his life toward his secret plan to abstain from annihilation. However news of his son's fame reaches Heihachi which makes him curious of Kazuya's power, and he finally decided to test his son's strength, announcing the King of Iron First Tournament not long after, and to ensure his son's apperance he puts the empire of the Zaibatsu as the prize. Much to Heihachi's surprise, he was beaten by Kazuya who ironically tossed Heihachi off a cliff. However, Heihachi managed to survive but he lost both his fame and family. Having spent his previous years indulging in deviant acts instead of training, he vows to regain what he has lost and began training to regain what was once his. 
A Grandson ?
One day, Heihachi was visited by a 23-year-old man named Bo Kazama. Being informed that Bo was his grandson and hearing that a mysterious being, sounding extremely simmilar to Heihachi's secret weapon, killed his mother, Jun, Heihachi reasoned that this creature must thrive on the "strong souls" of others. Heihachi then decides to train Bo to use him as a decoy to lure his weapon toward him.
==King of Iron Fist 2==
Heihachi finally 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 and his devil form a power something Heihachi dreams of having. Afterward, he tosses Kazuya (who had become too powerful to control) into a volcano and believed he killed his son. Heihachi then leaves by helicopter, and while holding onto a ladder the volcano erupts, as Heihachi smiles. Heihachi then continued scheming to further develop the Zaibatsu, Heihachi organized "Tekken Force", the Zaibatsu'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. 
==Ogre==
Now back in control, He sets up a secret excavation of Central American ruins by the Tekken Forces and a year later unearths an unusual find. They were annihilated by the mysterious being. Heihachi then confirms that the mysterious being is the legendary Ogre, and took action to realize his life's goal: to capture Ogre and therefore rule the world. 
==King of Iron Fist 3==
A year later, with Bo's training complete, Heihachi declared to the world that the third "King of the Iron Fist Tournament" was forthcoming. At the same time he noticed that Bo, the youngest of Mishima bloodline, began to show the same dangerous power Kazuya had. Heihachi decided to dispose of Bo after he lures Ogre, in order to end the doomed destiny of the Zaibatsu and save himself from the invasion. During the tournament Heihachi appeared and forced Bo to fight him in order to lure out Ogre, but kept this from Bo. Instead, he told him that he wanted to test Bo's abilities and determine whether or not he was strong enough to fight Ogre. Eventually, Bo defeated his grandfather, and Ogre who was defeated by Bo's best friend Forrest Masters, absorbed Heihachi's power allowing him to become True Ogre. True Ogre then appeared before him. Angered by the sight of his mother's killer, Bo engaged True Ogre in a fight, fueled by rage. Bo defeated True Ogre and had avenged his mother at last. Suddenly due to the extreme battle True Ogre violently exploded. Mere seconds after his victory, Bo is attacked by Heihachi's Tekken Force soldiers, and received multiple gunshot wounds. Slowly succumbing to death, Heihachi shot Bo in the head, therefore killing his own grandson. However, when Heihachi turned his back and walked away, he saw the bodies of his soldiers before him, and turned around to see Bo morphed into his devil form, Devil Bo. Bo then slammed Heihachi through a wall of the temple and violently hurled Heihachi down into the ground. Finally, Bo spread his wings and flew off. Heihachi, weakly, sat up and watched as his grandson, Devil Bo, disappeared into the night.
==Tekken 4==
However Heihachi only cared that he failed to capture Ogre. He made his researchers collect blood and tissue left behind by the explosion 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 Bo. During the search, Heihachi learned that the body of his son, Kazuya - whom he killed 4 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 Bo'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. 
==Coup==
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; although he was put into a coma. Heihachi wakes up only to find out that the King of Iron Fist Tournament 5 has already ended.
==Tekken 6==
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 Bo Kazama is the new head of the Mishima Zaibatsu, he is enraged and declares that he will get everything back, saying"The Mishima Zaibatsu is mine!". During the King of Iron Fist Tournament 6 (which he secretly entered), he was defeated by Lars Alexandersson, who is later revealed to be his illegitimate son. 
==Death==
After the tournament, Kazuya assumed control of the Zaibatsu and Heihachi spends the next several years conspiring with numerous members within the Corporation and the Zaibatsu to attempt a coup, but Kazuya finds out and goes directly to Heihachi, resulting in the two fighting once again. Kazuya easily defeats his elderly father but decided to pity his once mighty enemy suggesting to him that he stay down and die with pride. Moments later as he contemplates his son's words, and his own life, a woman appears from the shadows, points her gun at Heihachi, and says “you don’t know me but you killed my father 7 years ago.” Heihachi just looks up at her baffled and Chun Li continues “My name is Chun Li Wulong, daughter of Dorai Wulong.” Heihachi still baffled says to himself out loud “Chun Li?” as she puts a bullet in between his eyes killing Heihachi Mishima.
==Legacy==
Despite all the pain and suffering Heihachi has caused, he is attributed to making the Zaibatsu the conglomerate it is known as today, far surpassing the ideas of his father Jinpachi. Heihachi's foresight that the invasion would come eventually became true, and Raiden kept his word not saving Heihachi nor his sons biological or adopted from Shao Kahn when he absorbed the souls of Earthrealm. However it is Heihachi's grandson Bo that does what he was too afraid to, participating in the finals of Mortal Kombat defeating the sorcerer Shang Tsung and Outworld's emperor Shao Khan, thus saving Earthrealm.
