A seventh playable character has been announced for upcoming XBLA fighter Skullgirls. Valentine is both a ninja and a nurse who attacks her opponents with medical equipment including bone saws, defibrillators, injections and dead bodies. Her bio states:

Valentine is the only survivor of the Last Hope, a group of special Anti-Skullgirl Lab operatives. Before meeting their end at the hands of the Skullgirl, the Last Hope worked for the mysterious Lab Zero and performed duties ranging from reconnaissance and sabotage to advanced research.

Now Valentine dutifully serves the Skullgirl, carrying out her will from the shadows. She keeps to herself, so much of her true nature and personality are unknown.

Skullgirls is due out early 2012.
