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 appeares in the non-cannon 3rd movie Bleach: Fade to Black.

Appearance
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

Personality
Beeing born from siblings wishes to erase all memories of Rukia, Rukia's original personality is far from present and this Dark Rukia only seeks to destroy everything, that comes in the way of siblings desires to have Rukia for themselves.

Bleach: Fade to Black
When Rukia, who had her memories stripped, finally begins to remember people, Renji Abarai amongst others, the sister declares that she would never forgive Ichigo Kurosaki for trying to steal Rukia from them. She then proceeds to wish that she, her brother, and Rukia will become one, and it is granted, resulting in a twisted form of Rukia (picture to the left), referred to as "Dark Rukia" in the trailers. Renji deals with any other enemies for Ichigo, leaving him to do whatever necessary for "that woman."

Ichigo is forced to fight Rukia, but never attempts to actually attack her, instead only evading her attacks. He desperately asks her to remember, earning a reply that Rukia will erase her memories of him, destroying their bond. Ichigo, however, retorts that as long as he remembers her, the bond can never be broken." Dark Rukia is almost at the point of decapitating Ichigo, when she is interfered by Byakuya Kuchiki's kidō. Byakuya and Renji inform Ichigo that Rukia is turning into a Hollow and must be destroyed.

Ichigo refuses, emphasizing on his bond with Rukia again, to which Byakuya replies that he may do as he wishes, and breaks the kidō and steps out. Dark Rukia immediately rushes to Ichigo again, but Ichigo states that it is his turn to give her power this time, much as she had done on their first day of meeting. He stabs her with Zangetsu, and gives her his power. With this, Rukia transforms back to a shinigami, and immediately collapses to his arms. He hugs her with one arm, as all other shinigami apparently regain their lost memories.
