Tekken 2

2 years after the King of the Iron Fist Tournament , the Mishima Zaibatsu, under the leadership of Kazuya Mishima , has become more powerful than ever before and is involved in many illegal operations. While his father Heihachi Mishima was rather ruthless in his endeavors, Kazuya acts completely without a conscience. He hires assassins to eliminate any of his critics and rivals, extorts money from several businesses and organizations, and smuggles endangered species to conduct genetic experiments on them. The reason for his evil deeds is that he has allowed the Devil within him to consume his soul and mind as a result of his hatred towards Heihachi.

Kazuya is sentenced to being arrested by animal rights activist and operative Jun Kazama for his experiments. Heihachi on the other hand, whom Kazuya had defeated and thrown off a cliff 2 years ago, has climbed back up and is training himself, plotting to overthrow Kazuya and take back the Mishima Zaibatsu. In an attempt to rid himself of Heihachi and his enemies once and for all, Kazuya announces the King of Iron Fist Tournament 2, with a large cash prize of $1,000,000,000,000 , knowing that Heihachi will appear in an attempt to get his revenge. When Jun enters the tournament and eventually comes face to face with Kazuya, she tries to arrest him, but instead, the two cannot help being drawn to one another, propelled by a mystic force beyond Jun's control.

Besides her duty to arrest Kazuya, who smuggles protected animals, she wants to free Kazuya of his evil power and drops out of the tournament as a result. Meanwhile, during the tournament, Heihachi defeats the opposing fighters, including his adopted son Lee Chaolan , who had sided with Kazuya and worked for him as a secretary at the Mishima Zaibatsu. Despite his victory, however, Heihachi was defeated by Kazuya's old rival, Paul Phoenix , in the semi-finals of the tournament. Thus, Paul had earned the right to have a rematch with Kazuya.

Later on, the tournament officials reinstated Heihachi, allowing him to replace Paul in the finals when the latter was forced to forfeit after getting stuck in traffic due to a multi-car collision on the expressway and, therefore, unable to make the match on time. At some point during this time, Jun was able to cause an internal conflict within Kazuya, weakening Devil's hold over him. Despite her efforts, Jun fails to prevent Kazuya from going on to meet his father, Heihachi, in the tournament finals, to which Heihachi confronts Kazuya, and they battle once again. Kazuya is too weak to overpower Heihachi because of the internal conflict between his evil side - Devil - and his good side - an unknown entity called Angel, which was brought forth after his past meeting with Jun.

After defeating Kazuya in the finals, Heihachi throws Kazuya's unconscious body into a volcano before escaping on a helicopter just as the volcano erupts behind him, taking revenge and regaining the Mishima Zaibatsu. In the meantime, Jun became pregnant after her past meeting with Kazuya during the tournament, resulting in her leaving everything behind to raise her newborn son .
