Kwannon

Revanche/Psylocke

Japanese assassin who infamously swapped bodies with the X-Man Psylocke. Briefly becoming an X-Man, Kwannon contracted the Legacy Virus and died, got better, got her body back and now goes by Psylocke.

Not much is known about Kwannon's life, not even her last name, She was however a mutant gifted with empathic and low level telepathic abilities. After years of ninja training, Kwannon became the top assassin for Japanese crime Lord Nyoirin, who was deeply in love with her. However she and Matsu'o Tsurayaba, assassin of rival group the Hand. Kwannon and Matsu’o feared their line of work would put them on opposing sides but, respecting each other as warriors with honor, they vowed to fight to the death should they ever be forced to directly fight each other. When the interests of Nyoirin and the Hand came into conflict, Kwannon was honor-bound to face Matsu'o in combat. During the battle, she fell off a cliff suffering severe brain damage leaving her in a coma. Seeing this, Matsu’o abandoned his mission and retrieved Kwannon, bringing her to the Hand’s labs, promising to find a way to heal her.

On her grave, Matsu'o and Psylocke chose to engrave as a tribute the epitaph "Kwannon, love that transcended body and soul". She was buried in Wolverine's private cemetery in Japan.
