Her second, alternate costume shows her dressed in the burnt, ripped remains of a dark brown dress, with bandages wrapped around her arms, shins and instep. Her default 'costume' appears to have her otherwise nude body mostly covered in purple with a short, dark brown hair, shiny body paint or oil, as if she had been submerged in it to her chest. She has many demonic traits, such as glowing yellow eyes and a devil symbol tattooed on her upper right arm which resembles that of Jin Kazama's.
Unknown appears to be a tortured soul which has been enslaved by the 'Forest Demon' (which takes the form of a wolf-like appearance and appears behind her in fights, controlling and mimicking her actions). Unknown (アンノウン Announ ?) made her debut in 1999 in the non-canonical Tekken Tag Tournament, where she serves as the final boss.
