 Unlike the original Tekken Tag Tournament, the game's sequel features a storyline although it is still not the series canon. Just like last time, it is more of a "dream match", giving fans the opportunity to play as almost every character in the series up to that point, including some of those that had apparently been missing in the main Tekken storyline, in addition to the character roster of Tekken 6. In the story, Heihachi Mishima has developed a rejuvenation serum, which, as it name suggests, has the ability to regress his appearance and power. After consuming it, Heihachi hosts another King of Iron Fist Tournament, sensing powerful challengers who would come to the tournament.
