Tekken 6
Plot

Following Jin Kazama's victory against his great-grandfather, Jinpachi Mishima, in the previous King of Iron Fist Tournament, he is now the new head of the Mishima Zaibatsu special forces. Jin uses the company's resources to declare independence, becoming a global superpower, severing its national ties and openly declaring war against all nations over the following year. This action plunges the world into an extremely chaotic spiral, with a large-scale civil war erupting around the globe and even among the space colonies orbiting the planet. Meanwhile, Kazuya Mishima, Jin's father, who has risen to lead G Corporation, places a bounty on his son's head. In retaliation, Jin announces the sixth King of Iron Fist Tournament to lure Kazuya out.
As the war continues to erupt, the field leader of Mishima Zaibatsu's Tekken Force, Lars Alexandersson, has rebelled from the army along with several of his soldiers. However, Lars loses his memory during an attack by the G Corporation and spends some time recovering it. Accompanied by an android, Alisa Bosconovitch, Lars ventures throughout the world, avoiding the Mishima Zaibatsu's manhunt for him while also trying to recover his past. It is eventually revealed that Lars is actually the illegitimate son of Heihachi Mishima, who has gone into hiding since his supposed demise in the last tournament, and has been trying to take the Mishima Zaibatsu from Jin's hands. After coming into contact with several allies, including his adoptive brother, Lee Chaolan, Lars confronts the G Corporation and Mishima Zaibatsu's headquarters. Jin reveals he had sent Alisa to spy on Lars' actions all along. Disabling Alisa's safe mode, Lars is forced to confront his former teammate, who leaves with Jin to Egypt.
Helped by one of his allies, Raven, Lars goes to Egypt. He meets an astrologist named Zafina who provides them with information about the clash of two evil stars that will awake an ancient evil who will destroy the world. This evil, Azazel, is a demonic monster responsible for giving birth to the Devil Gene and is currently bound in an ancient temple. Lars confronts his half-brother Kazuya in front of the door leading to Azazel's chamber and fights him. Lars and Raven enter the chamber and confront Azazel, whom they seemingly defeat. Outside the temple, Lars confronts his half-nephew Jin, who uses Alisa to attack him. Lars is forced to damage Alisa and, enraged, beats up his nephew, when he mocks her uselessness. Following his defeat, Jin admits that his reason for launching the war was to awaken Azazel and destroy him, freeing the world from a greater threat than the war itself. Also, in doing this, he would free himself from the Devil Gene, as Azazel can only have a physical form through negative energies of the world. Revealing Azazel can only be destroyed by someone with the Devil Gene, Jin confronts and attacks the revived Azazel, sending them both plummeting to the desert. Lars requests Lee to use his technology to fix Alisa and goes to another mission. Raven unearths Jin's body in the desert and notes that Jin still has the Devil mark on his arm, implying that Azazel's demise did not free him from the Devil Gene.
