Tekken is a fighting game and is the first of the series of the same name. It was released at arcades in 1994 and on the PlayStation in 1995 and was later released again in Tekken 5's arcade history mode. It was developed and published by Namco.
A worldwide martial arts tournament is nearing its final, with a large purse of prize money to the fighter who can defeat Heihachi Mishima in the final round of competition. The contest is sponsored by the giant financial group, the Mishima Zaibatsu. There are eight fighters that remain after winning death matches all over the world. The winner of the tournament will receive The King of the Iron Fist title. Only one will have a chance at defeating Heihachi and taking home the prize money and fame. The player is initially able to select one of those eight fighters at the start of the game, each one having their own personal reasons for entering the tournament aside from the prize money.
Kazuya Mishima is the main character. Heihachi's biological son, he was thrown into a ravine by his tyrannical father when he was five years old. Heihachi, believing his son was too weak to ever inherit his conglomerate, decided that if he were truly strong enough, he would be able to survive the fall and climb back up. Kazuya barely survived a fall that left him with the scar prominently visible on his chest. Fueled by hatred for his father, he enters the tournament to exact his revenge.
Although all playable characters in Tekken have their own ending upon completion of their particular scenario, depicting events following the tournament as if they were the one victorious, it became a staple in later Tekken games of having only one character's ending as the true canonical one, and the following sequel's storyline is based on what happened after that particular ending.
