Fan Casting Viper in Darren Aronofsky's The Wolverine

Noburo Mori's secretary—and Shingen Yashida's most lethal weapon. Viper is a cold-blooded assassin, a poison expert, and a master manipulator who uses seduction as a tool and cruelty as a currency. She serves no one but herself, playing all sides against each other while waiting for her moment to strike. She is fascinated by Logan, seeing in him a kindred spirit—another weapon without a master. But Viper's interest is never innocent. She will destroy anyone who gets in her way.
