Tekken 4, set 21 years after
Tekken 2. Kazuya was revived by G Corporation (a genetics-company rival of the Mishima Zaibatsu), and allowed the company to perform experiments on him to learn the nature of his Devil Gene. He vows revenge on Heihachi in the King of Iron Fist Tournament 4 and to extract the half of his Devil Gene in the body of his son, Jin Kazama. Kazuya defeats Heihachi and tries to confront Jin. Jin defeats Kazuya and Heihachi in battle, but spares their lives. In
Tekken 5, Kazuya and Heihachi are assaulted by a squadron of Jack-4s (machines sent to assassinate them by G Corporation for the Tekken Force raid on the corporation's laboratories) after Jin's departure from Hon-Maru. Kazuya jumps out of Hon-Maru, leaving Heihachi to die. Vowing revenge on the traitors, Kazuya enters the King of Iron Fist Tournament 5. During the tournament, Kazuya crosses paths with
Raven, who recognizes him after seeing him flying away from the Hon-Maru. Kazuya defeats Raven and interrogates him. When he makes Raven talk, Kazuya discovers that he was betrayed by G Corporation, and that something was awakened from under Hon-Maru. Kazuya realizes what Heihachi has done, and speculates that, in fact, it is his grandfather
Jinpachi Mishima, who is somehow controlling the Zaibatsu now. In
Tekken 6, as G Corporation's shadow head, he converts it into a military company which is the only opposition to the Mishima Zaibatsu (led by Jin), which has begun world conquest and declared war on several countries. The world sees G Corporation as its only savior, although Kazuya intends to kill Jin and dominate the world himself. He uses the company's influence to stop Jin from world domination.

Lars Alexandersson, before he can face Jin. They fight, and Kazuya is forced to leave. Artist
Takayuki Yamaguchi based one of Kazuya's
Tekken 6 costumes on a
robot. In
Tekken 7, Kazuya's mother is revealed as
Kazumi Mishima, who died while trying to kill Heihachi. In the story, Kazuya sends an army of Jack-6 robots to the Mishima dojo to eliminate Heihachi. The warrior Akuma says that he was sent by Kazumi to kill Kazuya and Heihachi, later confronting Kazuya at G Corporation's Millennium Tower and revealing his debt to Kazumi for saving his life from an unknown critical situation he was in. Surviving defeat by Akuma, Heihachi secretly captures images of the battle in which Kazuya transforms into his devil form. He broadcasts the images worldwide, exposing Kazuya's nature to undermine public trust in G Corporation as the Zaibatsu's opponents in the war. In the final battle at the mouth of a volcano, Kazuya transforms into his devil form and defeats Heihachi. He throws him into a lava pit, seemingly killing him. Akuma resurfaces, having survived the previous blast. Kazuya transforms into his final devil form and they battle once more, with the outcome unknown. In
Tekken 8, Kazuya is confronted by Jin on the streets of New York City. Kazuya easily defeats Jin and knocks him unconscious with a devil beam. After the battle, Kazuya decides to confirm his coming out as a devil, while setting up the eighth King of Iron Fist Tournament, with the finals being held in Rome, as the means to continue his previous mission to absorb Azazel, in order to become a true devil, having had learnt that Azazel's physical body was destroyed by Jin, and Zafina is under Sirius' protection after sealing the monster inside her left arm. As the primary star of despair, Kazuya absorbs the desires of the human race to fuel his avarice in destroying the nations' hierarchies and prepare to temporarily recover Azazel's physical body. Kazuya uses a joint assault by the allied armies of Yggdrasil, UN and Sirius to his advantage at the end of the tournament's quarter final matches. As Jin and his allies arrive at Yakushima, Kazuya initiates his warring plan against the allied forces who side with Jin. Kazuya is confronted by Lars, who reminds Kazuya of Heihachi after delivering a headbutt. Despite this, Lars loses to Kazuya and is nearly killed when Jin appears in devil form to save him. Despite Jin's new power, he is overwhelmed when Kazuya prepares to obliterate Yakushima with a massive energy attack. As Devil Jin struggles to stop the blast, an apparition of his mother appears in a vision, who grants him the power of purification. Transforming into a new form known as Angel Jin, the latter deflects Kazuya's energy attack into the ocean below, causing the ground below them to launch into space, which serves as the battle ground for Jin and Kazuya. As both Angel Jin and True Devil Kazuya clash their fists at full power, they completely lose their devil powers, and thereby erasing Azazel out of existence. Despite this, upon landing back to Earth, Kazuya engages Jin in a vicious, final battle. After an extremely difficult struggle, in the canon ending, Kazuya is finally defeated but spared, and he is later found by a seemingly-alive Jun. In an alternate ending where Kazuya wins, he throws the unconscious Jin off a cliff and resumes his leadership of G Corporation, vowing that he will rule the world despite having lost the devil gene.
