Dark Rukia

Dark Rukia is an alternate form of Rukia Kuchiki, resulting from her being merged with Homari and Shizuku, resulting in a non-vizard Hollowification. She only appeared in Bleach: Fade to Black. Instead of having a Zanpakuto, she is wielding a gigantic, double-edged scythe. Her outfit appears to be completely different, and she is also barefoot, although she frequently ventures in bare feet while wearing her normal kimono as well. Her powers and abilities increases greatly, and appears to fight differently, as opposed to her current self.

Trivia

 * Dark Rukia is playable in the Bleach video game, Bleach: Heat the Soul 6.
