Kazuya Mishima (三島 一八 Mishima Kazuya?) is one of the main characters in the Tekken series. He appears in all of the Tekken games except Tekken 3, in which he only made two cameo appearances. Although he is seen as the main protagonist and hero of the first Tekken game, Kazuya is one of the main antagonists of the series ever since Tekken 2. Most importantly, Kazuya is the son of Heihachi Mishima and Kazumi Mishima, the love interest of Jun Kazama and the father of Jin Kazama. He's also the half-brother of Lars Alexandersson, the adoptive brother of Lee Chaolan, and the grandson of Jinpachi Mishima.
In the original entry to the franchise, Kazuya was considered to be the primary protagonist, and for all intents and purposes, there was no reason to believe differently. According to differing sources (such as Tekken: The Motion Picture and a brief scene in Ling Xiaoyu's Tekken 5 ending), Kazuya was actually quite frail and timid as a boy and was the victim of years of abuse at the hands of Heihachi. Indeed, Kazuya originally entered the first King of Iron Fist Tournament in order to face off against his father, who was played up to be a corrupt corporate tyrant. Kazuya's clothing of choice, simple white pants and red gloves and footpads, even helped to draw parallels to another "mysterious loner" hero, Street Fighter's Ryu. So most people (both within the game and in real life) simply wrote Kazuya off as the cliché fighting game hero.
There was only one clue as to Kazuya's true intents and nature: his secret PS One palette swap, which turned out to be Devil.
Tekken 2 saw Kazuya's true nature revealed in full. After killing his father (or so he thought), instead of bringing justice and honor to the Mishima Zaibatsu and righting the wrongs of his father, Kazuya repeated the corrupt practices of his father and turned it into an even much more ruthless and evil organization. While Heihachi was merely ruthless (though he had some standards), Kazuya was completely void of conscience or any compassion at all. He hired assassins to eliminate innocent people for the sake of his own pleasure (such as the father of Eddy Gordo), he attempted to extort money from several businesses and many organizations, and he even went so far as to smuggle endangered animal species, and conducted genetic experiments on them (Alex and Roger). Of course, the reason for his evil deeds was because he had sold his soul to the Devil all those years ago, and had allowed the evil within him to fully consume him.
However, Kazuya still had some sense of goodness within his heart, which gained more and more strength after he first met Jun Kazama, resulting in Angel, who constantly battled his evil side, though this would turn out to be his downfall. Heihachi managed to take advantage of his son's confusion caused by this internal war and defeated him in the second King of Iron First Tournament. Kazuya was then thrown into a volcano and killed, while the Devil in his body escaped and eventually made contact with Kazuya's son, who succeeded his father as the series' new protagonist.
Of course, G Corporation eventually located Kazuya's remains and at this point, they regenerated his body and made a deal with him to remain hidden within G Corporation's labs and be tested on. Kazuya had learned from his mistakes; the next time he faced Heihachi, he wanted to be in full control of his Devil powers. Of course, this plan did not go as Kazuya intended; Heihachi ruined it by invading G Corporation and stealing their research.
Since his original appearance, Kazuya's character has gone through many transformations: From hero to villain, from villain to anti-hero. Whatever was left of his good side appears to be totally suppressed by his Devil persona. Kazuya no longer fights against his darker side, and the two seem to have come to mutual terms, as Kazuya can call upon Devil whenever he likes now (such as in his Tekken 5 introduction). In Tekken 7, Kazuya seems less cruel than in previous Tekken, he even goes so far as to be more sentimental seen, that he reproaches Heihachi for having killed his mother.
In Project X Zone 2, Kazuya maintains his behavior in the main games but is also shown to be grumpy and rude towards other characters particularly because of the feud of his family, such as his father Heihachi and his son, Jin who became his partner. He also has shown interests in the other characters' performance such as Estelle's skills in writing a book about parents and children and hunting curse monsters when they spoke to Natsu about the broken curse. Kazuya also recognizes Ryo Hazuki's father who is the master of Hazuki-ryu Ju-Jutsu when he encounters Ryo Hazuki much to his son's confusion. Kazuya also dislikes people who are trying to getting hold of his actions which Jin tries to warn them about it and a prime example shows when Phoenix Wright was encountered by them due to his role as a lawyer and detective and became nervous to make trial on courts due to his actions for murdering people in the main games as well as media reporters such as Ulala who wants to know more of the Mishima family feud. Like Jin, Kazuya is also confused when Segata Sanshiro was encountered as he recognizes both being created by the producer of their game, Katsuhiro Harada or simply referring to his surname as Harada.
At five years of age, Kazuya found out his mother died at the hands of his father and attempt to get revenge against him. Unfortunately, Kazuya was defeated immediately and thrown off a cliff by his father, who claims that his son is weak and will have to survive and climb back up if he is to be his true son as well as his successor. Kazuya survives the fall and makes a deal with the devil in order to survive solely to murder his father. In the years prior to the events of the original Tekken, Kazuya enters martial arts tournaments all over the world, becoming an undefeated champion due to the Devil Gene within him, (only Paul Phoenix ever managed a draw with him). When the first King of Iron Fist Tournament is announced, Kazuya takes the opportunity to get back at him, setting the stage for the first game.
In reality, it is revealed that Kazuya was born with devil's power through his mother, and due to a result of his revenge against his father for killing his mother, and being thrown off a cliff by him, it awakens Kazuya's Devil Gene during his deal with his devil side.
Kazuya enters the tournament and makes it to the final against Heihachi. Apathetic towards the tournament's considerable prize money, Kazuya engages his father in a vicious, bloody battle in which Kazuya emerges victorious. Kazuya then proceeds to throw Heihachi's broken body off the same cliff Heihachi threw Kazuya off many years ago and smiles with his revenge completed.
Ending Description, "A Father's Fall": Having beaten Heihachi, Kazuya picks Heihachi's body up and throws it off the cliff, and smiles in satisfaction.
By the time of the second tournament, Kazuya has been the Mishima Zaibatsu's CEO for two years and engaged in much more evil actions beyond that of Heihachi Mishima. Around the same time, Kazuya hears the news that Heihachi is coming for him and to take back the Mishima Zaibatsu. Kazuya announces the King of Iron Fist Tournament 2 in order to lure his foes out for the pleasure of destroying them. During the tournament, Kazuya encounters a contender, Jun Kazama, and impregnates her with his son before leaving her to raise the child alone. Eventually, Heihachi makes it to the final round to face Kazuya and defeats him due to a battle between the light in him, represented by Angel who was brought forth after his meeting with Jun Kazama, and the darkness within him, represented by Devil. As a last resort, Kazuya transforms into his Devil Form and continues the fight atop the roof of the Mishima Zaibatsu headquarters, but Heihachi still emerges victorious due to his training to take back the Mishima Zaibatsu. In retribution, Heihachi throws Kazuya's body into the mouth of a volcano and escapes on a helicopter as the volcano erupts.
Ending Description, "Evil Smile": Kazuya is shown to have expelled and defeated Devil. Feeling pitiful for using such strength without controlling it, Kazuya starts to walk away. However, without knowing, Devil starts to rise again and is about to kill Kazuya with his eye laser. Although, as he fires, Heihachi appears in front of Kazuya and blocks the attack. Kazuya then grins, picks up his father's body, and uses him as a human shield. Even though Devil uses many eye lasers, none of them close to harming Kazuya, instead apparently killing Heihachi. As Kazuya throws Heihachi's body and Devil hits it away, Kazuya finishes Devil off with a Dragon Uppercut, and smiles with satisfaction, having rid himself of both Devil and Heihachi.
He is shown in Jin's memory of his mother. Kazuya in the memory flashes indicating his father's cursed blood relation is influencing his bid for vengeance against the God of fighting, Ogre. He also appears in Eddy Gordo's ending as the man responsible for his parents' deaths'.
Shortly after his demise at Heihachi's hands, Kazuya is recovered by G Corporation, a cutting-edge biotech firm and rival to the Mishima Zaibatsu. With help from the scientists, Kazuya slowly learns to control the power of the Devil Gene within him over the next twenty years, but as he begins preparing to take revenge and gain power, G Corporation is raided by Tekken forces on Heihachi's orders to acquire Kazuya's remains. Kazuya ambushes the Tekken Force and promptly defeats them, promising to come for Heihachi next. Around the same time, Kazuya learns of the existence of his son, Jin Kazama, and seeks to capture him with the intention of stealing Jin's devil power.
Kazuya enters the King of Iron Fist Tournament 4, despite knowing it is a trap by Heihachi. At the seventh stage, Kazuya is slated to fight Jin, who disappears. Kazuya is declared the winner by default and sent to the final round, where he meets Heihachi and demands to know his son's whereabouts. After winning the fight, Kazuya is taken by Heihachi to Hon-Maru, a Mishima compound in the woods, where Jin is being held captive. Once inside the compound, the Devil Gene brainwashes Kazuya's mind again and tries to steal Jin's Devil power, but is unsuccessful because of Jin's Kazama blood. Kazuya regains control and awakens Jin through psychic taunts, but is unable to defeat Jin in the following fight, and knocked unconscious.
Ending Description: Heihachi and Kazuya arrive at Hon-Maru. When Kazuya sees the body of Jin, the Devil Gene takes control of his body and tells Heihachi that 20 years earlier, he lost a part of himself (which is inside Jin), and he plans to regain it back. After knocking back Heihachi with telekinesis, he attempts to absorb the Devil Gene out of Jin. However he fails and when he loses control of his power, Kazuya once again reigns dominance over himself. He yells for Jin to rise, which he does, and Jin prepares to fight his father. After defeating Jin, Kazuya walks over to his body and successfully sucks the Devil Gene out of him. In triumph, Kazuya transforms into Devil (Using an appearance from Tekken 2 with a tail and scars) once again.
Following their defeats to Jin, Kazuya and Heihachi are ambushed by a squad of Jack-4s, who have been sent by G Corporation to destroy Kazuya as they no longer need him. Kazuya and Heihachi are forced to work together to fight the Jacks until Kazuya throws Heihachi into a group of Jack robots and leaves him to die in the ensuing explosion. When a mysterious man takes over the Mishima Zaibatsu and announces the King of Iron Fist Tournament 5, Kazuya enters to track down those who betrayed him and discover the sponsor's identity.
During the tournament, Kazuya crosses paths with Raven, who calls Kazuya a "coward who ran away from danger". He defeats Raven and interrogates him, it is during this little conversation that Kazuya finally learns who is holding the tournament: his grandfather, Jinpachi Mishima. It is unknown how far Kazuya progressed through the tournament.
Ending Description: Kazuya defeats and holds the dying Jinpachi in his arms. Kazuya reflects on his youth, spent affectionately training with his beloved grandfather. After a moment of nostalgia, Kazuya's true side surfaces, one of his eyes turn red alerting Jinpachi who is too exhausted to react, and he punches through Jinpachi's chest, destroying him heartlessly and turning him to dust. Satisfied with himself, Kazuya grins and looks back, as if ready to kill his next opponent, with an evil laugh.
Despite not winning the fifth tournament, Kazuya discovers the division of G Corporation that tried to kill him, thinking that he may be too much of a threat; in retaliation, he kills them all in revenge to gain all the power for himself, becoming the head of the company and opposing the Mishima Zaibatsu, led by Jin who has begun world conquest and declared war on the world to destroy a greater evil. By this time, the world's population sees G Corporation as its only savior, though Kazuya plans to destroy Jin and take over the world himself with an iron fist. Kazuya uses the company's influence to his advantage: to stop Jin from taking over his plans for world domination, Kazuya places a bounty on Jin's head for whoever can manage to capture him dead or alive and decides to enter the King of Iron Fist Tournament 6 (announced by Jin) to settle the score once and for all with his son.
During the tournament, Kazuya along with the G Corporation arrive at a remote area somewhere in the desert and he feels an overwhelming power within a large corridor/temple and is soon confronted by an entity named Azazel, who is believed to be the reason for the Devil Gene but they are interrupted by the arrival of Jin who has also felt this power and believes that he must win this battle to save the world and destroy the Mishima curse or bloodline but he believes that in order to achieve this, Kazuya, Azazel, and himself must all die. Kazuya later encounters Lars Alexandersson, a rogue Tekken Force leader who he discovers to be his half-brother. The battle ends without an outcome with Kazuya merely leaving and warning his half-brother about their fate being Mishima.
Ending Description: Kazuya is shown leaving Azazel's temple when the Tekken Force suddenly appear out of nowhere to destroy Kazuya (possibly a mission from Jin Kazama). In order to prove his dominance, Kazuya suddenly shows the unconscious body of Devil Jin in his hands to the crowd. Seeing this as a "Mission Accomplished" sign, the Tekken Force then lay down their weapons and salute him. Kazuya grins and laughs evilly, knowing that he has now defeated Jin and can gain more power.
Kazuya was raised as the heir to the Mishima Zaibatsu but rebelled against his father Heihachi. After awakening the power of the devil within him, he's finally able to control it.
Several decades ago, Kazuya confronted his father Heihachi for the murder of his mother. He desperately tried to fight his father, but Heihachi easily overpowered and defeated the boy. Kazuya was then tossed off a cliff.
In the present day, Kazuya watches from G Corporation tower as Heihachi announces his return and the announcement of the King Iron Fist Tournament 7, not surprised that his father is still alive. Learning that his father is searching for Jin, Kazuya tells his subordinates to hasten the preparations for his plans.
Later, Kazuya sends his Jack-6 army to kill Heihachi, who happens to be targeted by Akuma at the Mishima Dojo. However, after learning that Akuma was sent by his mother to kill both Heihachi and Kazuya himself, he disbelieves it, then maniacally laughs and deems his mother's task to kill him and Heihachi as absurd. He also wants to know how powerful Akuma is.
In the same time he suspects Heihachi faking his death at the hands of Akuma, he is soon confronted by Akuma on a later day, and they fight on top of G Corporation Tower after he dismissed his men not to engage Akuma due to his powers can beat them easily. Overwhelmed by his opponent's amazing powers, Kazuya transforms into the devil to increase his powers, not knowing that his devil form has been caught on camera by the Mishima Zaibatsu. Kazuya and Akuma are then attacked by Heihachi via a laser attack from a satellite that destroyed G Corporation tower. Although Kazuya survives the attack, public opinion is turned against G Corporation due to his devil form exposed to the world. Vowing to have the last laugh as a counteract on Heihachi, Kazuya shoots a Devil Blaster at Heihachi's satellite, causing it to plummet down to Earth and destroy an entire city. The world mistakenly believes that the Mishima Zaibatsu destroyed its own satellite, and public opinion is on G Corporation's side once again.
A few hours later, Kazuya finally confronts Heihachi inside a volcano. As they fight, Kazuya changes into his devil form and defeats Heihachi. But his father musters all of his remaining strength and defeats him, causing him to revert back to his human form. Even though the two of them have become severely weakened at this point, they continue to exchange blows when Heihachi head butts Kazuya. Looking up at the man he has always hated for all of his life, Kazuya finally kills Heihachi with a fatal blow to the chest. He then takes his father's corpse and tosses him into a river of lava.
Shortly afterwards, Kazuya is once again confronted by Akuma, who has also survived the attack at G Corporation tower. Transforming into the devil once again, Kazuya fights Akuma in a heated battle. In the end, Kazuya fires a powerful Devil Blaster at Akuma's Hadoken, and the collision destroyed the volcanic surroundings.
Although the final outcome of the battle is unknown, Kazuya's influence over the world is still present, as G Corporation is not ending the war and various nations face an incoming invasion. Considering how Jin is asked by Lars, Alisa, and Lee to defeat and kill his father once and for all, it is assumed that Kazuya not only survived, but actually defeated Akuma.
Kazuya appears in Tekken: The Motion Picture as one of the movie's main characters, exploring his relationship with Jun Kazama and his motivations for entering the 1st King of The Iron Fist Tournament.
Ending Description: Jin is defeated while Kazuya stands over him. He then snarls at a weakened Jin and then proceeds to walk away. Suddenly, Jin rises with vengeance (possibly showing Devil Jin spawning). Kazuya promptly turns around with a smirk and prepares for a fight.
Kazuya in Jin's Ending: Jin picks up an unconscious body of his father and archenemy, Kazuya. Jin is about to finish him with a single punch, only to have paused and dropped Kazuya's body back in the ground. He is then seen with his hands shaking as he falls down to his knees. This restraint is possibly due to "Kazama blood" influence or his mother's spirit taking control of him.
Kazuya in Angel's Ending: Angel stands over his unconscious body, puts her hand over his forehead and takes away the evil spirit. When he gains consciousness and wakes up, Angel is nowhere to be found.
In the 2010 live-action film Tekken, Kazuya is the main antagonist and is portrayed by American actor Ian Anthony Dale. In this version, he has facial hair and bears none of the video game character's bodily scars. Kazuya is Heihachi's right-hand man in Tekken Corporation, wishing to take over his father's company. Also, rather than being a hand-to-hand combatant, Kazuya relies on melee weapons such as axes and Eskrima sticks. Furthermore, the Devil Gene subplot is not used in the film. At the end of the tournament, he is defeated by his son, Jin Kazama.
Kazuya appears in the crossover game Street Fighter X Tekken. He was first revealed as one of the first few playable characters at San Diego Comic-Con International in 2010, along with Nina Williams, Ryu, and Chun-Li.
In the game, Kazuya (who is still the head of G Corporation) learns of the mysterious box known as the Pandora, which crash-lands in the Antarctic. He then plans to use the box's power to increase his Devil Gene, defeat his son Jin and take control of the Mishima Zaibatsu in his quest for power and to take over the world. At that moment, an old foe appears from the shadows: Nina Williams. Nina decides to accompany Kazuya on his trip to the Antartic. Kazuya accepts her assistance, but due to her relationship with the Mishima Zaibatsu and Jin, she has to do everything Kazuya tells her to despite the fact that she hates him.
During their journey, Kazuya and Nina run into Ryu and Ken Masters. Nina suggests to leave them be, not wanting to bother them, but Kazuya takes an interest in the two warriors and their power. Realizing that he could "use a warm-up" before arriving at the Antartic, he challenges them both to test his devil powers and their strength, much to Nina's dismay.
Ending Description: After defeating Akuma, Pandora's box opens. Kazuya and Nina then walk up to the box. Suddenly, Nina walks ahead of Kazuya and stands before him, much to his confusion. She then tells him that he can't have the box and that someone else wants it more, possibly Jin. Knowing her true intentions and that she means his son, Kazuya summons his soldiers from G Corporation, who had camouflaged themselves in the snow in case something like this would happen. Nina then runs and the screen immediately turns black with gunshots fired. Then it's revealed that all the soldiers have been defeated quickly, presumably Nina's doing. Despite her treachery, Kazuya still obtains the box, knowing that this is all that truly matters, he plans to take it back to his company in order to fully restore his body as well as the Devil Gene resting inside him.
In Tekken: Blood Vengeance, Kazuya is one of the film's main antagonists. He's still the head of G Corporation, as well as the boss of Anna Williams, who he orders to recruit Ling Xiaoyu as a spy (knowing that Jin would never harm Xiaoyu) to gather information on Jin's old school friend, Shin Kamiya. He later arrives in Kyoto at Kyoto Castle, where he finds Xiaoyu, Shin, Jin, Alisa Bosconovitch and a surprisingly alive Heihachi. After Heihachi ruthlessly kills Shin, Kazuya, Jin, and Heihachi have an epic three-way brawl and he's rendered unconscious by his father. After Heihachi's seemingly defeated, Kazuya confronts his son. After Jin declares to him that Kyoto will be his grave, Kazuya transforms into Devil Kazuya and smashes his son through the wall, taking the battle outside. Jin attempts to fight back, but his father easily defeats him. Devil Kazuya then urges him to transform into Devil Jin. Xiaoyu begs Jin not to, but Alisa puts her out of harm's way by declaring to take down Devil Kazuya by herself. However, Jin shuts her down immediately afterwards. Annoyed that Jin has been using a "doll" to do his work, Devil Kazuya stamps on Alisa and, with one single stomp crushes her in half, throwing Xiaoyu into despair. Afterwards, Jin finally transforms into a Devil, though his form is not yet complete as he battles his father. Devil Kazuya then tells his son that he's left with no choice but to finish him if he wants to end the Mishima Bloodline. He then easily defeats him and immediately believes that he's victorious. But suddenly, Jin finally takes control of his new form, surprising Devil Kazuya. His Devil powers now utilized, he finally defeats Devil Kazuya, telling his father that the Devil's power is his and sending him plummeting into a nearby waterfall. Devil Kazuya then tells his son that this isn't over before doing so.
Kazuya returns as a playable character in Tekken Tag Tournament 2. He retains his moveset from Tekken 6 with new moves added as both of his normal and devil forms are now one due to having the same fighting style as well as matching the current story that states how Kazuya attained full control of Devil ever since Tekken 4.
Ending Description: After Kazuya defeats Unknown, he absorbs her power (represented by the signature purple ooze on her body vanishing and washing over Kazuya instead.) Kazuya transforms into his Devil Form from Tekken: Blood Vengeance, laughing madly and triumphantly as he flies into the night. The absorption is similar to how Devil Jin absorbs Jinpachi's powers in Tekken 5.

Kazuya appears in Tekken Revolution as a playable character.
Kazuya appears as a playable character in Tekken Card Tournament. As his in-game information reads, he becomes more powerful and his cards' abilities activate when his health is at a set amount, which is a drawback since his best cards require very low HP in order to activate. He also specializes in dealing relatively powerful attacks, and can drain his opponent's health and draw quickly, but sometimes at the cost of his own health. He can also take away parries, and can weaken and parry his opponent's attacks, ideally punch attacks, and can strike without worry thanks to his cards that give him protection when striking. He also obviously has little to no basic cards that grant him healing abilities. Overall, he has good strength and great abilities, and a slightly roughly average draw ability, but he's recommended for anyone that doesn't mind losing HP to tap into his more powerful abilities.
Kazuya is the main protagonist of the prequel to 2010 film.
Kazuya is one of the most basic characters in the series. His moveset furthers powerful single strikes, and despite them being mostly slow and/or unsafe on block, they do a lot of raw damage. Most of Kazuya's best moves are predictable and hard to surprise with, so his most rewarding method of play is centered around block punishment. In fact, Kazuya's greatest assets are his punishing moves, like the Electric Wind Godfist, one of the best, if not the best punisher in every game he's in. In summation, he's overall best used as a defensive character, and a good timing is required to main him.
Starting with Tekken Tag Tournament 2, Kazuya gains the ability to morph into his Devil form at will. His Devil form gives him some demonic powers, like the ability to fly and shoot laser beams. Also changes slightly his moveset, most notably giving him the ability to perform the Twin Pistons move from a standing position, which can be used as a solid launcher move for juggle combos. However, he lost most of D/F+1 follow-ups in Devil Form.
His Rage Art has him doing two consecutive punches and transforms into Devil Kazuya to rake his opponent with a powerful Devil's Beam. This ability is also retained in his powerful devil form along with his Rage Art of his own during the battle against Heihachi and later Akuma.
In Tekken (Mobile), Kazuya's Rage Art has a minor change, instead of raking his opponent by Devil Kazuya's Devil's Beam, he maintains to hit his opponent with two consecutive punches followed by Hell Lancer and heavily knocks his opponent with a Dragon Uppercut and having his arm crossed on his downed opponent.
Kazuya fights using Mishima Style Fighting Karate. In a style similar to Shotokan karate.
