->'''Appears in:''' ''1''-''7'' (playable), ''8'' (archival footage), ''Tag''-''Tag 2'', ''Death by Degrees'', ''Revolution''

Hiroshi Watanabe)

->The father of Kazuya, a badass extraordinaire who owns two pet bears (both named Kuma) and is a self-made man who owns the Mishima Zaibatsu...after toppling his father Jinpachi. He threw Kazuya into a ravine to see if he would be considered a worthy successor and riled him up further by adopting Lee Chaolan. Years later, Heihachi created the King of Iron Fist Tournament, where Kazuya entered, kicked his ass, and threw him into the very same ravine where Heihachi threw him before. Heihachi survived, writing Kazuya a letter saying, "You should have found a steeper cliff." He then hosted a second tournament where he battled Kazuya again, paid him back, and threw him into a ''volcano''.

->For years, Heihachi built up a good reputation with his Zaibatsu while hiding his ambitions. When he's approached by his grandson Jin Kazama, who wants to avenge his mother's death at the hands of Ogre, Heihachi uses him to lure Ogre out. Once Jin beats Ogre, Heihachi betrays Jin by shooting him in the head, only to be smacked back by Devil Jin and thrown out of Ogre's temple through a wall. Later he found out that Kazuya was still alive, and hosts the 4th tournament to lure his descendants for his plans. Jin foils his plan, then he gets ambushed by Jack robots, then Kazuya betrays him, and the Jack robots self-destruct on him after dogpiling him. [[NoOneCouldSurviveThat Heihachi survived]], being no ordinary man, but was rendered unconscious for the entirety of the 5th tournament while Jin took over the Zaibatsu. During ''Scenario Campaign'', his plans to take back the Zaibatsu are interrupted in their early stages when Lars shows up and confronts him, revealing that he is Heihachi's son from an affair he had in the Netherlands. The two fight and Heihachi is defeated. As Lars leaves, he surmises that Lars will end up doing his work for him, and continues to lay low. This pays off when, in the end, Jin sacrifices himself to stop the being known as Azazel and Kazuya leaves out of boredom. With Jin out of commission, but still alive unbeknownst to anyone, Heihachi seized control of the Zaibatsu. He now continues the war against G Corporation and Kazuya, hoping to engage in one final battle to decide their fate.

->Before his decisive battle, Heihachi would finally reveal his side of the story to a lone reporter who had collaborated with Lars Alexandersson. In the past, Heihachi spent his days studying the martial arts under his father Jinpachi's tutelage, alongside a fellow student named Kazumi Hachijo. Eventually the two fell in love and married, giving birth to Kazuya. However, soon afterward, Kazumi began acting strangely and showed odd signs of not being herself. She would sporadically show signs of sickness and randomly lash out at Heihachi violently, trying to attack him with an almost demonic fervor. Initially, Heihachi tried to dismiss these incidents as some sort of illness, but in truth, Kazumi was the first known bearer of the Devil Gene, which had partialy compelled her violent outbursts. This eventually came to a head one fateful night. Kazumi had finally truly awakened to her Devil form, and approached Heihachi fully with the intent to kill him, revealing that her "illness" had all been faked from the beginning. She had lied to Heihachi since long before their marriage, staying that she only married him under orders from her family, the Hachijo clan, who saw Heihachi as a great potential threat to the world if left unchecked, and now the time had finally come to fulfill her clan's mission and assasinate him. The battle ended in tragedy when Heihachi was ultimately forced to kill his own wife when it was clear that she would not stop, no matter how much she pleaded that the love between them was real.

->Ever since that day, Kazuya had hated his father and wanted vengeance against him. Heihachi throwing Kazuya off of the cliff all those years ago was, in fact, a test to see if he carried the same Devil Gene as his mother. The reveal that Kazuya was alive and well, still seeking revenge on him, confirmed it to be true. Heihachi had since made it his mission to ensure that all bearers of the Devil Gene were eradicated from this world, including his own grandson Jin. During that time, he had conceived Lars as another test to see if contact with Kazumi had somehow resulted in him becoming a carrier of the Devil Gene as well as to dispel any rumors surrounding him. With the truth now revealed, Heihachi sends the reporter away to tell the world his story, knowing of his allegiance with Lars but also giving him a mournful look before having him knocked out. Prepared to face his destiny with a solemn but firm resolve, knowing that he's come too far now to stop, Heihachi heads to the very volcano he threw Kazuya in all those years ago, and the two have their final battle. A battle that, despite neither side giving an inch, ultimately results in Heihachi's defeat - [[KilledOffForReal permanently]]. The legacy of Heihachi Mishima was finally ended at the hands of his own son, who killed him with a decisive blow and laid waste to the Mishima Zaibatsu, the company he had run and used to exert control over the world for decades.

->In gameplay, Heihachi is a powerful pressure character, renowned for his exceptionally fast mids and dangerous highs. Heihachi's game plan revolves around getting in the opponent's face and continually putting the pressure on until they are forced to back off or sidestep. If they move to challenge him, then Heihachi has several strong counter hit tools to catch these attempts and launch into combos. Unfortunately, his defense is subpar, and he must play aggressively or lose match momentum.

[[folder:Tropes A-J]]
* AbusiveParents:
** While his dad was practically a saint (DemonicPossession aside), Heihachi thinks chucking your son off a cliff or adopting another son solely to foment a sibling rivalry are sound parenting skills. Then he tries to kill them when the [[SarcasmMode ungrateful brats]] don't appreciate all he's done for them.
** He also extends his abuse over the generations. Grandson? More like live bait to attract an ancient monster that feeds off fighting skills! Did he screw up your plan by killing the beast? A bullet between the eyes. Later on, he ropes his son and grandson into being future subjects for his research.
** Notably, his [[HeroicBastard second biological son]], Lars, who Heihachi did NOT raise, turned out to be a pretty good guy. ParentalAbandonment is a blessing when it comes to being Heihachi's child.
* AdaptationalJerkass: Heihachi in ''Bloodline'' takes after his characterization shown in ''4'' and beyond. As such, he is shown to be significantly more abusive towards Jin than the caring grandfather act shown in the games. Because of this, Jin figures out much quicker that Heihachi is not the man he believes to be. Heihachi's betrayal at the end is much more openly evident, significantly softening its impact compared to Jin's ending in ''Tekken 3''.
* AlasPoorVillain: His backstory in ''Tekken 7'' shows [[spoiler: that his wife Kazumi tried to kill him many times. He chose to ignore it, thinking his wife might have mental issues he's not ready to deal with, hoping it goes away. Only to discover that her intentions were genuine; she was sent there to get close and kill him from the beginning. He is forced to kill her and this begins the Mishima's BigScrewedUpFamily.]]
* AmbiguousStartOfDarkness: ''7'' reveals that [[spoiler:he was forced to kill Kazumi, who had revealed that she had married the Mishimas to kill him. This leads to his hatred towards Kazuya and Jin; both of whom hold the cursed blood that drove Kazumi to make her attempt on Heihachi's life. But, the reason Kazumi went after him was that, in one year, he wrested control of the Mishima clan from Jinpachi, who had wanted to stray away from being a warmonger and focus his devotion to martial arts. Made more ambiguous by the fact that while throwing Kazuya off a cliff was ''after'' he killed Kazumi, his brutal actions of imprisoning his father and leaving him to starve to death, is implied to be a bit before that fateful battle, meaning Heihachi was always capable of extreme cruelty to his family.]]
* AnimalMotifs: His black dogi features a tiger's face at the back. Kazumi's similar motif in ''7'' hints that this is most likely a tribute to her.
* AnimeHair:
** The only hair he has left grows in two farcical upwards spikes like that of his son and grandson. ''This'' must be part of Mishima genetics, not the Devil Gene, as his father has even ''wilder'' hair.
** When he's rejuvenated in ''Tag Tournament 2'', his hair regrows to an improbably sweet swallow's tail. In the series timeline, even when most everyone was younger -- in the first two games -- Heihachi was already balding, so this is the first time we see him with a full head of hair. This hairstyle [[CanonImmigrant made its way into canon]] in ''Tekken 7'''s flashbacks that take place before the first game.
* AntagonisticOffspring: ''Tekken 5'' reveals him to hate his father Jinpachi, who was a good-hearted man. He took control of the Mishima Zaibatsu from him by betraying him and later imprisoning him in Hon-Maru when he attempted to take it back. Jinpachi would starve to death.
* AntiHero: A NominalHero in ''Tekken 2'' where he becomes TheProtagonist opposing his son Kazuya who has [[RogueProtagonist ironically become the]] BigBad after taking over Heihachi's empire and [[EvilerThanThou becoming even worse than he is]]. He's still a huge prick who only seeks to regain his former power, and he quickly returns to an antagonistic role from '' Tekken 3'' onwards.
* AntiVillain: While Heihachi took over the Mishima Zaibatsu for his gain and has a tendency to be unnecessarily cruel, he has some redeeming traits, like forming genuine relationships with Kuma and Xiaoyu, and his actions against Jin and Kazuya were only that to wipe out the Devil Gene, having an understandable reason to want to destroy it considering witnessing what it did to his wife. This makes him and Jin alike.
* ArcSymbol: A lot of promotional material for ''7'' features his Mishima Zaibatsu logo, a three-pointed star above a hexagon (like a thinner variant of Mitsubishi's three-diamond logo). This also appears in his ''Fated Retribution'' outfit on the right side of his chest.
* ArchnemesisDad: Like his son, he's on both sides of this trope - his war with Kazuya is pretty much the central plot of the games, but in ''5'' it turns out he wasn't on good terms with his own dad either. The latter is an inversion, though - his father was a pretty decent guy; Heihachi turned on him because he ''[[AntagonisticOffspring wasn't]].''
* AssholeVictim: [[spoiler:Regardless of how he had a HeelRealization in Tekken 7, Heihachi's death was long overdue, considering all the pain, death, and suffering he had caused for a vast majority of his life.]]
* AsskickingLeadsToLeadership: How he regains control of the Mishima Zaibatsu at the beginning of ''7'', as well as his method of employing Claudio.
* BackToBackBadasses: Father and son team up to kick robot ass! First featured in the opening movie of ''5'', and became a playable segment in the Story mode of ''7''.
* BadassInANiceSuit: In Story Mode of ''Tekken 7'', once he reacquires the Mishima Zaibatsu, he wears a nice suit that would make [[Film/TheGodfather Vito Corleone]] proud. The suit is even called "TheDon" in the character customization menu. Even before that, a winter tuxedo was one of his clothing options in ''Tekken 3''.
* BaldOfEvil: Until his more youthful appearance as first revealed in ''Tag 2''.
* BattleAura: Occasionally seen as a blueish-white coloration around him, especially in ''Tekken 7''. However, it seems to almost be like a physical representation of his {{Determinator}} status rather than an explicit supernatural force, as if to contrast with the Devil Gene powers of the rest of his family.
* BigBad: In the first, third, and fourth installments, where he's the organizer of the King of Iron Tournament and Kazuya's main nemesis.
* BigBadEnsemble: He and his son Kazuya shared the BigBad position for the majority of the series as a whole until Heihachi was KilledOffForReal by his son in ''7''.
** Even before the first game, his actions also ended up clashing with his wife's family, the Hachijo clan and Azazel, who they worshipped, which would ultimately set up almost everything else in motion.
* BlackSheep: While the Mishima family is full of evil people, Heihachi was the only one whose descent into villainy was of his own volition. Jinpachi was a good man who fell victim to DemonicPossession, Kazuya and Jin turned evil because of Heihachi's actions against them (with Jin becoming a WellIntentionedExtremist who wants to purge the world of the Devil Gene by any means from his betrayal). Heihachi however became a power-hungry warmonger even before Kazumi's betrayal.
* BossRemix: The [[https://www.youtube.com/watch?v=9f2PXby0kL8 arcade version]] of his theme in ''3'' is a darker, more badass version of [[https://www.youtube.com/watch?v=dCTag_9WW5w Jin's theme.]] The [[https://www.youtube.com/watch?v=IEsO0vTvTj0 remixed version,]] on the other hand, sounds a bit like a SuspiciouslySimilarSong to [[https://www.youtube.com/watch?v=S7ejsNdvpxA "Rollin With Kid N Play",]] thanks to that bass.
* BrokenPedestal: Jin Kazama looked up to him during the events of ''3'' in training him against Ogre. It is clear in both of their endings that Heihachi will kill Jin after all is said and done. He failed in the latter's ending, in which became the reason Jin started hating everything about the Mishimas, including the Devil Gene.
* BulletCatch: Catches one in his ''teeth'' in ''6''[='=]s Scenario Campaign.
* CallBack: His endings in ''2'' and ''3'' are titled "A Son's Fall" and "A Grandson's Fall" respectively, referring to Kazuya's canonical ending in ''1'' (i.e. "A Father's Fall") where he drops Heihachi down the same ravine Heihachi threw him down as a child. Both of Heihachi's endings (the one in ''3'' is non-canonical) involve him [[ThereIsNoKillLikeOverkill dropping his relatives from a high altitude]].
* CharlesAtlasSuperpower: He's one of the biggest examples of a BadassNormal among Mishimas, having no connection to the Devil Gene whatsoever (even Asuka has her anti-Devil abilities). That said, he's such a skilled Martial Artist that he can deflect missiles with his fists, and headbutt bullets in flight, and when he was younger, he [[spoiler: killed Kazumi when she went Devil just to assassinate him]]. The OVA has him catching Michelle's axe (which she had thrown at his head) ''with his teeth and grinding it into pieces'' before spitting the shards out.
* ContinuitySnarl:
** ''3's'' main profile talks about Heihachi not knowing about Devil, this not only contradicts [[spoiler: ''Tekken 7'', where Heihachi knew about it since Kazuya was a kid]], it contradicts ''3'' itself since Heihachi's own profile describes him as being aware Jin has the same "dangerous power" as Kazuya.
** In ''7'' [[spoiler: Lars says that he was only conceived so Heihachi could prove without a shadow of doubt that he doesn't have the Devil Gene, but Lars is around 20 years younger than Kazuya, so Lars would only be conceived around 15 years after Kazuya was thrown off a cliff and only a few years before the first tournament, so it makes little sense that Heihachi decided to wait so long to confirm something like that.]]
* CoolOldGuy: While he can be utterly abhorrent to those he despises, he's also pretty funny and badass. He has some very light-hearted interactions with Kuma and Xiaoyu, and even his endings in ''5'' and ''Tag 2'' are quite comedic.
* CorruptCorporateExecutive: A thoroughly selfish man at heart, Heihachi's only interest as head of his family's conglomerate is to continue pouring its resources into wars and other destructive endeavors, something his father tried to distance the Zaibatsu from.
* ADayInTheLimelight: After dropping off plot importance in ''5'' and ''6'', 7 gives him the most amount of CharacterFocus yet. [[spoiler:Also comes with ADeathInTheLimelight [[KilledOffForReal that canonically sticks]].]]
* DeadpanSnarker: His attitude as he greets Kazuya after their last encounter.
-->"You should have found a steeper cliff."
* DegradedBoss: Happens to him ''twice'', no less. After the first game, he is removed as Mishima Zaibatsu head by Kazuya and has to fight through Kazuya's King of Iron Fist Tournament two years later to get it back (he does). Later on, he hosts the fourth King of Iron Fist Tournament and this time is declared the official winner but is ambushed at his Hon-Maru compound and presumed dead. He wasn't, and still wakes up in time to compete in the sixth tournament, hosted by his grandson.
* {{Determinator}}:
** Not even being blown up ''point-blank'' by a squadron of Jack-4s, shot through the air at breakneck speeds, and crashing into a monument in the middle of a forest miles away [[NoOneCouldSurviveThat is enough to kill Heihachi]]!
** This gets exemplified in ''Tekken 7's'' story mode. [[spoiler:In the final battle between Heihachi and Kazuya, the latter, in full devil form, lights him up with several lasers that create a massive explosion, but he still gets back up. The next battle scene has Heihachi with (visually) low health, to show that he's fighting to his absolute limit. After this, they are both exhausted, and keep trading blows for who knows how long until Kazuya finally deals the finishing blow to him.]]
* DidntSeeThatComing: Let's just say that Heihachi didn't expect Jin to come BackFromTheDead as Devil Jin, kill his Tekken Force {{mooks}} (complete with one being PunchedAcrossTheRoom into a wall with enough force that ''blood'' appears to gush out of his armor), [[FacePalmOfDoom drive him through the wall by his head]], and then pounce on him from the sky. Heihachi's reaction to #2 on the list is a look conveying [[OhCrap "Holy shit! Should I run or turn around?"]]
* DifficultButAwesome:
** While he also has the same EWGF-setups all Mishimas have (though since he's taller, shorter characters won't be continuously juggled by his), he has a huge set of solid mid-level and high-level attacks with very save frames and many ways to pressure on block thanks to those said attacks being very safe pokes. Just like Kazuya, he can take a hit-into-a-combo as far as possible when it lands it. The biggest thing you need to worry about is that Heihachi has a severe lack of solid-and-safe low attacks, making his 50/50's quite bad.
** Even with a buff to one of his low attacks in ''Tag 2'', it's still very atrocious on block like the rest of his available low attacks and thus his means of forcing open one's defense is focused on frame-traps and throws with very unsafe mixups.
** In the same sense as Kazuya having a "Perfect" variant of the Electric Wind God Fist, Heihachi has a Just Frame variant of the Thunder God Fist, which players refer to as the Omen Thunder God Fist (OTGF). It's a faster version of the move that not only launches the opponent, but also hits a grounded opponent, so a Heihachi player with above-average execution will be well-rewarded in mastering this.
** ''Tag 1'' is the first game where he got EWGF, and unlike Jin's, it was a special mid instead of a high. To compensate for this, his EWGF is even harder to do than Jin's and Heihachi is on the group of characters with the lowest HP on the game.
* DisappearedDad: He has two confirmed illegitimate children in Lars and [[spoiler:Reina]], but Harada himself has confirmed Heihachi has ''[[ReallyGetsAround dozens]]'' of bastards lying around.
* DivergentCharacterEvolution: He was originally a MovesetClone of Kazuya, but began to get more and more original moves and stances of his own from ''Tekken 2'' onwards.
* {{Egopolis}}: Played for laughs. In ''Tekken 3'' he promises Ling Xiaoyu he'll give her an amusement park if she wins the tournament. In her ending when she does, he fulfills his promise... and opens up ''Heihachi Land''... which earns him a NoHoldsBarredBeatdown from Xiaoyu.
* ElixirOfLife: In ''Tag 2'', his scientists concoct a serum that restores his youth. [[spoiler:In his ending, another dose is administered that turns out to be tainted with ''Kuma's'' DNA, [[OhCrap turning him into a bear.]]]]
* EnlightenedSelfInterest: In the years between ''2'' and ''3'', Heihachi brings world peace through the military and philanthropic actions of his Tekken Force. This isn't done out of the kindness of his heart but for the sake of positioning the Zaibatsu as a global superpower and gathering information on Ogre for his own malign purposes.
* EvenEvilHasLovedOnes:
** Though it's non-canon, Heihachi does attempt [[TakingTheBullet to save Kazuya from Devil's beam]] in the former's ''2'' ending. Too bad Kazuya [[ChronicBackstabbingDisorder exploits that for his own victory]], and the two never share anything but hatred canonically [[spoiler:besides Heihachi shedding a SingleTear right before their final battle in ''7'']].
** In Heihachi's (also non-canon) ending in ''3'', he looked genuinely sad when he had to kill Jin by dropping him from his helicopter after the latter displayed signs of the Devil Gene taking him over while being unconscious, mainly the marks appearing on his forehead.
** Despite killing his wife, Kazumi, Heihachi still loves her, and when Kazuya called him out for it in the ''Tekken 7'' trailer, rather than brushing it off, Heihachi stayed silent, one single tear running from his eye. And though Kazumi knows her husband must be stopped, she also fondly remembers and believes in the love they once shared.
** He cares about his pets, Kumas I and II.
* EvenEvilHasStandards: Heihachi may be a greedy, power-hungry, self-centered megalomaniac, but he treats women and young girls with the utmost respect and ''despises'' those who bully the weak. He also generously rewards those who serve him well or amuse him, if only because it would tarnish his reputation not to. Further, he expresses distaste at squalor and substandard living conditions, noting that if he ran the Zaibatsu, he'd ''never'' let things degrade to such a level.
* EvilLaugh: He also does this the most out of all the Mishimas. In one of his moves, he does this while dashing away from his opponent.
* EvilMentor: Was this for Jin prior to the third tournament. Heihachi was the one who taught Jin Mishima-style Karate, though he had his own agenda to do that, namely to turn Jin into a powerful fighter that could draw Ogre out, after which he would [[YouHaveOutlivedYourUsefulness dispose of Jin via bullet to the head]]. Though that last bit didn't work out thanks to Jin awakening his Devil Gene...
* EvilOldFolks: He's 52 as early as ''Tekken 1'', and only gets older from then on, being in his 70s by ''3''. He's been a dick most of his life, however.
* EvilVirtues: To him, Strength, Diligence, [[{{Determinator}} Determination]], and [[VillainousValor Valor]] are paramount. He is one of the series' strongest fighters [[BadassNormal despite lacking his son and grandson's Devil Gene]], always takes the full-measure with any conflict, possesses iron willpower and resilience to the point of [[MadeOfIron regularly walking off life-threatening injuries]], and will fight to his last breath regardless of who or what he's up against.
* FinalBoss: Of ''Tekken'', ''Tekken 4'', ''Tekken Advance'', and the ''Tekken Force'' modes in ''3'' and ''4'', as well as the spin-off ''Death by Degrees''. Sub-boss of ''Tekken 3'' (before Ogre and True Ogre) and he and his father comprise the first tier of bosses in ''Tekken Tag Tournament 2'' (True Ogre and [[spoiler:Jun/Unknown]] as solo battles comprise the second and third tiers).
* GameplayAndStorySegregation:
** He's playable in ''Tekken 5''; in the story canon, however, he never participated. [[ZigZaggedTrope That being said]], him not participating in the fifth tournament is a {{Retcon}} from ''6'', as his profile from ''5'' rather clearly says he woke up early enough to participate on it (Meanwhile his profile from ''6'' says that by the time he woke up the tournament was over), and he even shows up on the story mode of a few characters (Kazuya, Wang, Lee, Raven, Jack-5).
** Heihachi is ridiculously tough, and survived a bunch of attacks that would normally kill or cripple someone, despite this, he's on the group of characters with low HP in ''Tag 1''.
* GlassCannon: In ''Tag 1'', characters had different HP values, and Heihachi's was among the lowest (140, while the general value was 151, and the highest was 168). This is likely to balance out his high damage and, most importantly, his special mid Electric Wind God Fist, and it's worth noting this is the only time until Tekken 7 where EWGF is anything but a high (Kazuya has a Devil transformation in ''7'' which makes his EWGF into a mid).
* GoodScarsEvilScars: He has an X-shaped scar across his chest, but a [[XMarksTheHero hero]] he is ''not''.
* GreaterScopeVillain: While Kazuya became the BigBad of the series (or at least the Devil inside him), it isn't hard to argue that everything bad in the series is Heihachi's fault in the first place, not only because him throwing his son off a cliff opened him up to the Devil Gene, but also because of him wresting control of the Mishima Zaibatsu from Jinpachi and pushing it toward weapon development, leading the Hachijo clan to predict the danger he would become if left unchecked, which led him to kill Kazumi. And his desire to rule the world would eventually lead to him wanting to discover the secret of the Devil Gene after witnessing firsthand what it does, leading to him setting his crosshairs on Jin and vice-versa.
* GroundPunch: A new attack he gained in ''Tekken 7''. It causes the opponent to stagger, and if an opponent is lying on the ground when his fist hits the floor, it will pop them up high enough in the air for a potential juggle if they're close enough.
* GruesomeGrandparent: While not as much of an enemy as he is [[ArchnemesisDad with Kazuya]], he has every intention of offing his grandson Jin as well.
* GuestFighter:
** In ''[[VideoGame/SoulSeries Soul Calibur II]]'' on the [=PS2=]
** He's also a playable character in ''VideoGame/PlaystationAllStarsBattleRoyale'', appearing in his younger appearance from ''Tag 2''.
* HeartbrokenBadass: As shown in the story mode of ''Tekken 7'', [[spoiler:the death of his wife Kazumi was the chief reason his heart had hardened. The revelation that her Hachijou blood was demonic in nature, and that her blood was passed on to their son Kazuya, was what originally drove him to toss him off a cliff. Kazumi's death also preceded his takeover of the Mishima Zaibatsu from his own father Jinpachi, and the Zaibatsu's subsequent move to the military-industrial complex.]]
* TheHeavy: He's the one hosting the original King of Iron Fist tournament, drawing out Kazuya in the first game. He contributes some part to most of the games until 7.
* HeelRealization: Vaguely implied in ''Tekken 7'''s story mode. [[spoiler: Before his final battle with Kazuya, he brings in the reporter that's narrated the story thus far to give him exclusive info about his actions and misdeeds, including the revelation of what really happened with Kazumi, with the request to tell it to the world. Though he does go back to his {{Jerkass}} behavior and has the man knocked out and thrown out for being an associate of Lars in the end, when asked what he thought about the ongoing war, the reporter states that he saw a 'mournful look in his eyes'. Considering the circumstances, it seems Heihachi knew how much of a bastard he was and effectively gave a biography before marching off to find some resolution in this mess.]]
* HiddenDepths: As he is confronted by Kazuya in their final battle in ''Tekken 7'', a single tear falls from his eye. In a later trailer titled "Rage and Sorrow," he represents "Sorrow" as his reason for fighting, implying that there might be deeper reasons for his apparently evil actions all throughout Kazuya's life.
* HorrifyingTheHorror: Curiously he's been on both ends of this trope, and most cases are related to the Devil Gene.
** In Jin's ending in ''3'', once Devil Jin throws Tekken Force members past him, Heihachi briefly looks baffled before scowling. In his own ending, when he sees Jin is about to transform, he throws Jin out of the helicopter.
** Back in Kazuya's ''4'' ending, when Devil takes control of Kazuya, Heihachi is clearly scared.
** In ''7'', he does that to [[spoiler: Devil Kazuya. First by surprising Kazuya over how resilient he is, and later at the end of the battle after he briefly overwhelms Devil Kazuya and the transformation is turned off. It reminds Kazuya of the previous trauma Heihachi gave him [[https://youtu.be/totCBeK8Wno?t=4657 and Kazuya's eyes even look teared]].]]
** PlayedForLaughs in [[https://youtu.be/LP9xrhJznnk?t=170 ''5's'' Time Attack cutscene with Jack-5]].
* {{Hunk}}: One may protest, but he fits this down to a T. His younger self certainly does, at least.
* {{Immortality}}: This seems to be his main motivation in later entries; as if being MadeOfIron wasn't enough, he's now seeking a way of becoming young again, which he achieves in ''Tag Tournament 2'' when his scientists develop a youth serum and he tests it on himself, leading to him appearing as he does in that game (in fact, that's the only shred of a plot this game has - well, that and [[spoiler:Jaycee actually being Julia filling in for a friend]]).
* InSpiteOfANail: It's implied in ''Tekken 7'' that his StartOfDarkness would've happened anyway since he had still overthrown Jinpachi with plans to continue the warmongering business, but [[spoiler: having to kill his wife with his own hands in self-defense]] didn't help.
* JerkWithAHeartOfJerk: He's that heartless ([[StartOfDarkness but only because of his woes that resulted in the said cliff the first time around]]). He still trained said grandson since Jun disappeared, [[BrokenPedestal if only to prepare him for the third tournament as bait]].
* {{Jerkass}}: Ultimately, everything the ''Tekken'' series is and has been being a result of Heihachi's heartlessness and zeal. He sealed his father away under the Hon-Maru compound to seize the Zaibatsu (which brought forth Hachijo clan's attempts to assassinate him through his wife), he threw his son off a cliff to "make him stronger" and later in his life (upon learning of his survival), held the first King of Iron Fist Tournament to draw him close. Then 22 years later he brings his grandson into the third tournament (also one he hosted) to use as living bait for Ogre and shoots him when things don't go the way he wants. Even though Kazuya and Jin are both bitter enemies, Heihachi has earned contempt from both.
* JokerImmunity: Thrown off a cliff in ''1'' and comes back just fine in the next game. Was smashed through a wall in ''3'' and wasn't even scratched. Jin was about to kill him in ''4'' but an hallucination of Jun prevents him from doing so. ''5's'' initial trailers had Jack-4's blowing him up and he was a timed release character in the arcade mode, but he's still a mini boss with his own cutscene and can be played in ''5'' itself after a while. [[spoiler: ''7'' ultimately ends this pattern, as Kazuya kills him and even throws his body in the volcano they fought to make sure he stays dead. In ''8'' he's not on the base roster.]]
[[/folder]]

[[folder:Tropes K-Z]]
* KarmicDeath: After years and years of cheating the Reaper, karma seems to have ''finally'' caught him for good by the end of [[spoiler:''Tekken 7''. Forced into a fourth battle with his estranged son--whose life he destroyed mainly out of misplaced hatred for his wife's sins--the aging Heihachi ultimately proves no match for Kazuya's sheer hatred against him, even after Heihachi forced him off from his devil form, and meets his end after receiving a powerful, fatal strike to the chest (without Kazuya's gloves on). To add insult to injury, Kazuya then carries his lifeless body in yet another IronicEcho of their past fights. Only this time, rather than toss Heihachi down a cliff ''again'', Kazuya opts to finish the job once and for all by dumping his corpse down a volcano, to make sure he's DeaderThanDead. A fitting end for such a poor excuse of a "father"]].
* KickTheDog: Almost too many examples to list, some of which are as follows: He's imprisoned his own father (who was by all accounts good to him) and left him to starve to death, threw his own son down a cliff to test if he had a devil gene, and then openly regretted the fact that his son ''survived''. Adopted a child for the sole purpose of giving his son a rival, fathered many children and abandoned them and their mothers, used Jin as bait and then shot him when his grandson foiled his plans, and so on and so forth.
* KickThemWhileTheyAreDown: More like a stomp. Also, one of his victory scenes has him berating his unconscious opponent, holding them up by their hair, and shouting, "Come back when you're ready to fight!" before slamming their head back down and walking away in contempt.
* KilledOffForReal: [[spoiler: His ultimate fate in ''Tekken 7''. Despite putting up what is perhaps his most valiant effort seen yet in the series, he is ultimately no match for Kazuya, who kills him with a fatal, Devil Gene-empowered strike to the heart. And to ensure that he dies for good, Kazuya gives the deceased corpse of his father the same treatment that he gave Kazuya in ''2'': being thrown into a volcano. And unlike when Heihachi did it to him, Kazuya watches Heihachi's body fall into the lava to make sure that he's actually dead this time. His death is reflected by [[OutOfFocus his absence]] in ''8'', while Kazuya moved on to Jin for the family feud...though he is still present in spirit through his illegitimate daughter Reina, who inherited her late father's fighting style and ambition]].
* LampshadeHanging: [[spoiler: When Akuma says he promissed Kazumi to kill Heihachi in in ''7'', Heihachi immediately wonders why Akuma took so long to show up (A question many fans were wondering since Akuma was confirmed to be the guy who talked with Kazumi). Akuma's [[HandWave response]] is that [[BloodKnight he was waiting for Heihachi to become stronger.]][[note]]Which is absolutely in character for Akuma.[[/note]]]]
-->'''Heihachi''': [[spoiler: You're saying Kazumi told you to kill me and Kazuya...? Nonsense. If that were true, why only appear now?]]\\
[[spoiler:'''Akuma''': ''I was merely waiting for you to become stronger.'']]
* LargeHam: Ya think? "With this, the world will hail MY victory! Gwahahaha!"
* LastDance: [[spoiler:The final battle in ''7'' takes place from his perspective]].
* LaughablyEvil: Since the original ''Tekken'', he's been PlayedForLaughs just as often as he's been played seriously. Some of the weirder things he's done ([[ButtMonkey or been subjected to]]) are: left a bear (Kuma) in charge of his company while he left to fight in a tournament, made his own amusement park, had his company make a magic potion (which he drank without testing first), was forced to work as an "exotic" drink server with a bomb shaped like a bow-tie strapped to his neck...
* MadeOfIron:
** In ''Tekken 3'', in Jin's ending, Devil Jin picks Hei up like a ragdoll, smashes him through a solid concrete wall and drops him several stories below, leaving somewhat of a crater on the ground, before flying away. Though a little stunned, shortly after that Heihachi gets up completely unscratched.
** The intro of ''Tekken 5'' has him surviving being blown up by a group of Jack units rigged with explosives. In previous games he's a BadassNormal; from that moment onward he's apparently Superman.
** ''Tekken 7'' takes this to absolute absurd levels. [[spoiler: The amount of punishment Kazuya has to inflict on Heihachi to finally put him down is ridiculous. Kazuya throws the proverbial kitchen sink at Heihachi in his regular form, it's not enough. Then Kaz goes into his devil form, beats him down and blasts him, but Heihachi proceeds to get up. Another back and forth HowMuchMoreCanHeTake ensues and Kazuya ''finally'' takes him out and tosses him into a volcano]].
* MadScientist: Many storylines have him show interest in scientific supervillainy, namely in ''Tekken 4'' where he shows interest in combining the genetic material of Ogre and the Devil Gene to create an UltimateLifeForm. Sometimes, he also wants to take the power of the Devil for himself. In ''Tekken Tag 2'', he has his scientists create a formula that restores his youth [[spoiler:(and transforms him into a bear in his ending)]].
* AManOfWealthAndTaste: ''Tekken 6'' reveals that he dislikes Paul and Marshall Law, considering both horrible wastes of talent living in squalor. He also expresses disgust in several cities being ruined during Jin's war.
* ManipulativeBastard: Heihachi has been a two-faced piece of trash all his life, manipulating his biological and adopted sons against one another and politicking against his own father Jinpachi. However, his manipulation of Jin in ''3'' is especially cruel. Jin was naively convinced that Heihachi was a good grandfather, but Heihachi merely saw Jin as a weapon against Ogre and shot him in the back of the head once that purpose was fulfilled. This betrayal spurred Jin's struggle with the Devil within himself and led to a three-way Mishima war that would leave the world in ruins.
* ManlyMan: A ripped old man wearing nothing but a worn karate gi has an impossibly cool horned hairstyle and can match supernatural entities with his own raw strength and combat prowess. He gets even ''manlier'' with age. As for his guest appearance in ''Soul Calibur II'', 'Hachi needs no stupid weapons; he'll beat you senseless with his bare hands.
* MaternalDeathBlameTheChild: ''Tekken 7'' reveals an odd example. [[spoiler: Heihachi was forced to kill Kazumi in her Devil form, but it wasn't just Kazuya he was taking it out on. Throwing him off that cliff had a hidden purpose: to see if he inherited her Devil Gene based on whether or not he survived. When it turned out to be true, he knew he had to destroy them both, and eventually Jin as well.]]
* {{Miser}}: Seems to consider charity for its own sake extraordinary stupidity at best. In the ''Tekken 4'' endings, the only character he outright refused to hand over his company to (the prize for that tournament) was Yoshimitsu, specifically ''because'' he was a Myth/RobinHood type who robbed the rich to help the poor (of course, Yoshimitsu expected that and was in the middle of [[UnwittingPawn robbing him anyway]]). While Heihachi can appear generous in public, this is always to pass off as a VillainWithGoodPublicity or to otherwise get something in return.
* MotiveDecay: ''7'' establishes that he feared and loathed the Devil Gene after [[spoiler:Kazumi's failed assassination attempt on him while using her Devil form]], leading to him trying to kill Kazuya and his manipulative and murderous intentions for Jin. Once ''3'''s bombshell of what his hunt for Ogre was really about drops, however, it's clear that in his later years Heihachi himself began to covet the power of the Devil, working with lab projects and secret, inhumane experiments to find out how to tame it -- and, when presented an opportunity for his resurrected son and exhausted grandson to be gathered in one place, try to seize it by force, only to learn yet again that EvilIsNotAToy. By the end of ''7'', [[spoiler:he finally resolves his decay to instead try to destroy the Devil Gene once more, [[KilledOffForReal and fails.]]]]
* MrFanservice: His primary in ''4'' was a ''fundoshi''. In Lee Chaolan's ending in ''5'', he's introduced via a FemaleGaze shot of his ass, wearing nothing but a tight speedo with a bowtie. In ''Tag 2's'' character customization, while older characters his age are supplied with modest swimsuits that cover up most of their bodies, Heihachi and the other male characters get the fundoshi.
* {{Narcissist}}: You'd have to be a [[{{Understatement}} little bit]] in love with yourself to have the trophy of your fighting tournament be a model of your head.
* NeckSnap: In ''7'', [[spoiler:this is how he kills Kazumi after defeating her Devil form]].
* NeverMyFault: Implied as one way to look at his StartOfDarkness. Having already overthrown his father with his plans for the family business, [[spoiler: Kazumi had ultimately been sent to kill him to prevent all the damage and misery he would later cause]]. While he ''does'' feel guilty about [[spoiler: having to kill his own wife]], he may have decided to [[spoiler: focus the blame on the Devil Gene for making him go through with it]], instead of [[spoiler: acknowledging that his warmongering plans were why they were trying to kill him to begin with]] setting the stage for [[spoiler: his own attempt to put an end to the Devil Gene]]. Considering what it is, [[EvenEvilHasStandards Heihachi may still have some valid reasons for doing so anyway]].
* NobleDemon: He's a bastard that will kill you without remorse if you're a threat to his warmongering empire, but he is also [[PragmaticVillainy pragmatic]], intelligent about his methods, polite to women and children unless they tried to kill him, tries to avoid letting his territories be stuck in squalor, and firmly respects power and skill in other combatants [[BigScrewedUpFamily besides his own family]]. It says a lot that the world was in a better state when he was in charge of the Mishima Zaibatsu compared to when he wasn't and, despite some of his horrible crimes, there's a lot ''less'' people that hated him the long-term than Kazuya [[spoiler:or Jin, post-World War III]].
* NoOneCouldSurviveThat: Nuked by dozens of Jack robots? No problem.
* NoSell: Heihachi's CounterAttack (b+2+3) can intercept opponent strikes, but doing so also hurts Heihachi. If successful he tanks the hit, clutches their limb against his shoulder, and then pushes them to the ground with a fierce leg thrust but suffers some damage in the process.
* OffingTheOffspring: On his son ''and'' grandson, no less. None of his attempts at doing so succeeded for good; in fact, [[spoiler:he [[KilledOffForReal totally died]] instead]].
* PetTheDog: In the non-canonical Kazuya ending in ''Tekken 2'', Heihachi tried to cover Kazuya from Devil's laser beam. Kazuya [[ChronicBackstabbingDisorder responds by grabbing Heihachi and use him as a human shield from Devil's laser, and tosses Heihachi aside when he's close enough to uppercut Devil to death.]]
* PragmaticVillainy: While the Mishima Zaibatsu was more evil under Kazuya, that's more due to this trope than Heihachi being some AntiVillain. Heihachi wasn't as inclined to have people assassinated or make links with the criminal underworld, but he was still highly unethical at best. He was smart enough not to do anything overtly criminal (or at least, to not get ''caught'' doing it). He's still a thoroughly selfish, power-hungry bastard through and through.
* PreFinalBoss: Heihachi is fought in Stage 9 of ''3'', just prior to Ogre. If you play as Heihachi, you will face Jin instead.
* PromotedToPlayable: Was the unplayable final boss in the original arcade version of ''Tekken 1''. He became an unlockable character in the home port, and has been playable in every subsequent game (usually by default) [[spoiler:until ''8'', where he's only absent because he's KilledOffForReal (by his very own son!)]].
* TheProtagonist: In ''2'' and ''7''. In the latter case, the Story Mode has him playable in more chapters than any other character, including the final chapter where he faces off against Kazuya. [[spoiler: Not counting the Extra Match against Shin Akuma, of course.]]
* PsychoElectro: Some of his attacks have electrical properties, and he's an asshole. [[LikeFatherLikeSon Just like his son.]]
* RasputinianDeath: Before finally dying, he survives being tossed off a cliff, being punched through a wall by Devil Jin, blown up point blank by several Jack-4 robots, crashing into another place as a result of said explosion, sustaining Akuma's Raging Demon, and finally, blasted by several lasers at once by Devil Kazuya. What finally kills him is a heart-stopping, devil-powered strike to the chest by Kazuya, then getting thrown into a lava pit for good measure.
* ReallyGetsAround: According to WordOfGod, Heihachi is rumored to have maybe 18-25 children around the world, with only 9 being confirmed. This was most likely to prove that he doesn't have the Devil Gene. [[spoiler: Unfortunately one other child happens to have it: Reina.]]
* RecessiveSuperGenes: He's the only member of the Mishima family who doesn't have the Devil Gene. [[spoiler: Ultimately this isn't the case, as the Devil Gene only became part of the Mishima bloodline because of Kazumi, meaning Jinpachi didn't have it either.]]
* RefugeInAudacity:
** In the first two games, being dropped off a cliff is enough to keep him out of action for roughly two years. In the fifth, though, he takes multiple miniature nuclear bombs ''to the face'' and isn't even scratched; instead, he is thrown several hundred miles through the air and crash lands into the hard earth. He's mostly just annoyed.
** His way of taking care of Jin and Kazuya in his endings in ''5'' and ''6''. He straps them onto a rocket in ''5'', and sends them plummeting into Earth from a space station in ''6''. In the latter case, though, Kazuya [[TakingYouWithMe is not about to go gently into the night]], and [[HoistByHisOwnPetard successfully pulls Heihachi with him to burn up in the atmosphere]].
* {{Retcon}}:
** In ''2'' it was Kazuya who wanted Michelle's pendant during the second tournament. ''3'' retcons it to have been Heihachi who wanted it.
** In ''6'' Heihachi was surprised to find out he has another son, but in ''7'' [[spoiler: he's fully aware of Lars and even was conceived to confirm Heihachi himself doesn't have the devil gene.]]
** His original reasoning for throwing Kazuya off that cliff was to see if he was strong enough to inherit the Mishima Zaibatsu. ''7'' [[spoiler: changes the reasoning, and now Heihachi did it to confirm if Kazuya really has the Devil Gene.]]
* RetroactiveIdiotBall: ''Tekken 7's'' retcons caused a few of these surrounding Heihachi.
** Heihachi originally threw Kazuya off a cliff to see if he was strong enough to inherit the Mishima Zaibatsu, [[spoiler: and ''7'' retcons it and says that he only did so to confirm if Kazuya has the devil gene, but the game offers no explanation over why he didn't just kill Kazuya after confirming that he does have it.]]
** ''7'' has the [[spoiler: Hachijos as the source of Devil Gene, and despite Heihachi getting some interest in the Devil Gene in ''4'' (And if Leo's ''Tag 2'' ending is canon, he became interested in it even before ''3''), he seemingly never went after the Hachijos.]]
** [[spoiler: Leo's ending from ''Tag 2'' causes another one if the information it gives is canon[[note]]''Tag'' endings are generally not canon, but Steve's episode in 7 shows scenes from his ''Tag 2'' ending, but neither him or Nina mention the Devil Gene, with Nina saying the project was about creating super soldiers and nothing else, so either Namco quietly dropped the Devil Gene part that was mentioned in Leo's ending, which is connected with Steve's ending, or Nina isn't aware or simply didn't want to tell Steve about the Devil Gene[[/note], since it claims Heihachi was trying to create a synthetic Devil Gene since after ''2'', and while the experiment was a failure, with Steve being the only survivor, once Jin showed up, Heihachi could always try to get his blood in some way but seemingly didn't. To make it even worse, if Heihachi got interested in doing experiments with the Devil Gene during ''2'' and not after it, he could always get blood samples from Kazuya's body before throwing him off a volcano, but seemingly, he didn't do it.]]
* SelfMadeOrphan: Ultimately succeeded with his dad; as while killing him outright failed, he had to settle for [[CruelAndUnusualDeath sealing him away under the family home where he then died of starvation.]] Conversely, he is the target of his son and grandson [[BigScrewedUpFamily (and those two want to do the same thing to each other)]].
* SerialEscalation: Most of his endings tops the one before it. From dropping Kazuya off a cliff (in the backstory), he drops him into a volcano in the second game. In the third game, he throws Jin out of a helicopter. In the fifth game, he launches Kazuya and Jin into space. In the sixth game, he drops them ''FROM ORBIT'', but Kazuya screws him over as well by dragging him along for the fall.
* ShadowArchetype: To Lars. Being of Mishima blood, they both have the ability to fight off Devil Gene bearers without the need to gain extra powers. They both differ in ideologies however:
** Lars utilizes the Tekken Force Martial arts, and is the leader of a rebellion to make the world a better place while Heihachi utilizes his iconic Mishima-style martial arts and is a power-hungry warmonger and overthrew his father as the owner of the Mishima Zaibatsu.
** Their relationships with Jin also started off differently, with Heihachi's relationship starting off on the right track before outright betraying Jin by shooting him, triggering his devil state, leading to Jin becoming progressively more cynical to the point of becoming a DeathSeeker. Lars' relationship with Jin was not pleasant to start, having to rebel against him due to starting WorldWarIII, but after knowing his real purpose of doing it, Lars was willing to become allies with Jin put a stop to the war, which made Jin ''gain the will to live''.
** To put it simply, Heihachi is Lars if he fought for power instead of for a better future.
* SharedFamilyQuirks:
** His ''Tekken 2'' profile lists collecting geta sandals (The ones he wears in a bunch of costumes) as a hobby, similar to Kazuya's own hobby of collecting sneakers.
** In ''Tag 2'' and ''7'' he got more spoken voice clips where he says which body part he's hitting, for example, during b1, he hits the opponent on the face and says "kao", meaning "face". Jin does something similar, where he says "chest" when hitting their opponents on the chest.
* SilverFox: There's certain evidence within the ''Tekken'' universe that points him toward this.
* SleevesAreForWimps: His classic tiger-pattern gi has its sleeves ripped off, in case you weren't sure how tough this old man is.
* SmugSnake: Bar ''Tekken 2'', his plans rarely go how he wants them to. And he wouldn't have been in that situation if he hadn't lost to Kazuya in ''Tekken 1''.
* SocialDarwinist: He claims that the reason he threw Kazuya off the cliff is to test his strength as a worthy successor to his corporate empire, at one point claiming that he must have no fear. He will also immediately respect someone if they show enough ambition and resolve, so long as they don't stand in his way.
* TheStarscream: He's primarily driven to take control over Mishima Zaibatsu and advance his evil plans, and regain it if he lost control of it. According to ''7''[='=]s story mode, Heihachi took over what would become the Mishima Zaibatsu from his father Jinpachi due to his disagreements over Jinpachi wanting to turn it into something more peaceful. He also vows to take control of the Zaibatsu from Kazuya in ''2'', and Jin in ''6'', succeeding both times.
* StrawNihilist: Shades of this in the game, addressed in ''Anime/TekkenTheMotionPicture'' where he states to Jun that people's beliefs are killing themselves and others, and he thinks the world should be wiped clean so they can start again. Jun is utterly disgusted by this.
* StrongerWithAge: Not the case in Tag 2, since it suggests that he needed to become younger to keep up, and in his ending he even looks tired when the serum stops working and he becomes old again. [[spoiler: However that game works on an ExcusePlot, and as far as canon is concerned, Heihachi actually got stronger over the years according to Akuma, and there's very little to contradict this considering Heihachi can face off against him, and later Kazuya, to the point he managed to make Kazuya detransform during the battle.]]
* TheTrainsRunOnTime: Heihachi considers it beneath him to allow his company, or the territory it controls, to become shoddy, run-down, or inefficient.
* UltimateLifeForm: After encountering Ogre and witnessing his grandson transform into a Devil, he combines genetic material from the two to create an ultimate weapon for world domination.
* UnreliableNarrator: There are some hints that Heihachi's autobiographical story to the nameless reporter in ''7'' is not entirely truthful, as he paints himself in a far more heroic light than all other accounts indicate. His motivation is to increase his publicity for the war against Kazuya and G Corporation. He explains that he killed Kazumi in self-defense and wanted to eradicate the Devil Gene by killing Kazuya, justifying his continued conflicts against his progeny. However, this runs contrary to his past motivations of wanting to appropriate the Devil Gene for himself. Considering the sliding nature of Tekken's story, this version of events may only be true for ''7''.
* UseYourHead: His "Stonehead" throw (which a male opponent can keep going back and forth with him on). One of his moves is a headfirst forward lunge to his opponent. This is also the second hit of his Rage Drive.
* VillainProtagonist: A case could be made that Heihachi is the true protagonist of the ''Tekken'' series. He is, after all, the only one of his bloodline to be in every game, and he is always the driving force of the plot, whether he's the game's main protagonist/antagonist. WordOfGod has recently painted him in this light with the advent of ''7'', seeing as how they want it to be the final battle between the Mishimas. [[spoiler:And now that Heihachi is KilledOffForReal, looks like Jin Kazama (previously TheHero of ''3'') has to pick up the mess.]]
* VillainRespect: Heihachi is a typical Machiavellian villain. While all he cares about are his ambitions, he will still give credit to others when it's due. Heihachi generally likes people with strength, refined tastes, and manners.
** He was impressed enough by Ling Xiaoyu after she stormed his boat and beat up his guards to give her a full scholarship to his school and a panda bear for a bodyguard.
** During the Scenario Campaign in ''Tekken 6'', he only attacks women such as Ling and Anna after they stand in his way, and he feels he has no choice. He openly expresses distaste at fighting women.
** Kuma I and Kuma II are the only known characters that Heihachi ''always'' respects.
* VillainWithGoodPublicity: Founded the ''Tekken Force'' to promote world peace, repair the damage Kazuya had done to the Zaibatsu's public image, and [[BreadEggsMilkSquick hunt down and capture ancient demonic fighting gods to find out how to harness their power.]]
* VillainousValour: [[spoiler:In his final duel with Kazuya, he acts somber and almost respectful towards his son.]]
* VillainousLegacy: [[spoiler: Heihachi may be dead but he left behind a nasty little gift for his progeny: Reina]]
* WalkingShirtlessScene: If not clad in his dogi, he'll be shirtless. ''4'' has in a fundoshi.
* WellIntentionedExtremist: It turns out the real reason Heihachi had thrown Kazuya down the ravine all those years ago was because [[spoiler: of Kazumi's attempt on his life while her Devil Gene was active. With [[StartOfDarkness his trust destroyed, paranoia overcame him. Properly paranoid in thinking Kazuya was also embedded with the same power]]; combine that with Kazuya explicitly trying to kill him as well due to Kazumi's death, and Heihachi tossed him down the ravine to see if he had inherited the Devil Gene and thus survive the fall. [[GoneHorriblyRight He did,]] and thus Kazuya's FaceHeelTurn was cemented for the rest of the series.]]
* WouldNotHitAGirl: Heihachi considers himself a gentleman with chivalrous manners. He deliberately tries to be respectful to women and young girls, to the point that he is ''disgusted'' when he finds the Tekken Force (which he considers his even under Jin's command) attacking one lone girl. But, if any lady stands against him, he'll take them down all the same. [[spoiler:Oh, and he regretted killing his wife Kazumi, even if he would become the warmonger that the Hachijou clan feared he'd become.]]
* WrestlerInAllOfUs: Seriously. He has a ''powerbomb'' and an ''atomic drop'' as throws. In Anime/TekkenBloodVengeance, his grandson Jin discovered that Grandpa Mishima has added a German suplex to his moveset.
* YouHaveOutlivedYourUsefulness:
** In ''Tekken 3'' to his own grandson, whom he used to lure Ogre out of hiding and then tried to kill once the latter was defeated.
** The [[EasterEgg continue screen]] for the Jinpachi/Heihachi battle in ''Tag 2'' has him do this to Jinpachi, sending him plummeting down a trapdoor. [[RunningGag He sure is fond of those things]]...
* YouKilledMyMother: ''7'' reveals that he [[spoiler:killed Kazumi, his wife and Kazuya's mother]], providing another layer to Kazuya's RoaringRampageOfRevenge.
[[/folder]]

->In gameplay, Heihachi is a powerful pressure character, renowned for his exceptionally fast mids and dangerous highs. Heihachi's game plan revolves around getting in the opponent's face and continually putting the pressure on until they are forced to back off or sidestep. If they move to challenge him, then Heihachi has several strong counter hit tools to catch these attempts and launch into combos. Unfortunately, his defense has taken a major hit, and he must play aggressively or lose match momentum.

* AmbiguousStartOfDarkness: ''7'' reveals that [[spoiler:he was forced to kill Kazumi, who had revealed that she had married the Mishimas to kill him. This leads to his hatred towards Kazuya and Jin; both of whom hold the cursed blood that drove Kazumi to make her attempt on Heihachi's life. But, the reason Kazumi went after him was that, in one year, he wrested control of the Mishima clan from Jinpachi, who had wanted to stray away from being a warmonger and focus his devotion to martial arts.]]

* JerkWithAHeartOfJerk: He's that heartless ([[StartOfDarkness but only because of his woes that resulted in the said cliff the first time around]]). He still trained said grandson since Jun disappeared, [[BrokenPedestal if only to prepare him for the third tournament]].

** In ''6'' Heihachi was surprised to find out he has another son, but in ''7'' [[spoiler: he's fully aware of Lars and even conceived to confirm Heihachi himself doesn't have the devil gene.]]

** [[spoiler: Leo's ending from ''Tag 2'' causes another one if the information it gives is canon, since it claims Heihachi was trying to create a synthetic Devil Gene since after ''2'', and while the experiment was a failure, once Jin showed up, Heihachi could always try to get his blood in some way but seemingly didn't. ''7'' can make that even worse, because if Heihachi got interested in doing experiments with the Devil Gene in ''2'' he could always get blood samples from Kazuya's body before throwing him off a volcano, but seemingly, he didn't do it.]]
* SelfMadeOrphan: Attempted with his dad; he had to settle for [[SealedEvilInACan sealing him away forever under the family home.]] Conversely, he is the target of his son and grandson [[BigScrewedUpFamily (and those two want to do the same thing to each other)]].

* BadassNormal: Who needs the Devil Gene to kick ass? [[spoiler: He even defeated Devil Kazumi in single combat by pure martial skills, before his StartOfDarkness and before he had any idea of what the Devil Gene was!]]

** [[spoiler: Leo's ending from ''Tag 2'' causes another one if the information it gives is canon, since it claims Heihachi was trying to create a synthetic Devil Gene since after ''2'', and while the experiment was a failure, once Jin showed up, Heihachi could always try to get his blood in some way but seemingly didn't.
