Unknown

Unknown was introduced in Tekken Tag Tournament, and she hasn't made any other appearances since. A werewolf spirit-like creature seems to have possessed Unknown for it's own purpose, which is to complete itself, as shown in Unknown's ending. The creature accompanies her in battle and mimics Unknown's moves and actions. Since Tekken Tag Tournament's release, Namco has not, to this day, provided any clear explanation on Unknown. The comic book Tekken Forever was meant to explain who Unknown was, but it was canceled after only one issue. The Tekken 6 artbook stated that Unknown was originaly meant to be Jun Kazama's sister, but was dropped when the game became a spin-off.

Unknown and the wolf-like creature that possesses her aren't actually a tag team per se, as one cannot be switched out for the other. The wolf-like creature actually possesses Unknown to "even out" this disadvantage, while playing against her in story, she has the ability to regenerate lost health that is still red in her health bar, a trait normally attributed only to characters who are tagged out. Further more, Unknown is not knocked out until even the red bits of her health bar has been fully depleted (these traits do not carry over if a player plays as her).
