Fan Casting Nightshade in George Nolfi's Captain America

A brilliant young woman, Tilda Johnson grew up in poverty in Harlem. At the age of ten, she was already making strides in what would become her "werewolf serum", though her mother, teachers, and classmates at the public school she went to continued to think of her as "brilliant but lazy", not seeing that she had already surpassed most people with doctorates. Seeing in the world around her that crime paid, she decided to start her own criminal organization, mostly as a way to get out of poverty and fund her future experiments. Calling herself Nightshade – sometimes Deadly Nightshade – Tilda let herself get arrested on a drug charge mainly to get into a prison. Once imprisoned in the minimum security section of Ryker's Island penitentiary, she quickly enticed the male guards and started injecting the inmates and several guards alike with her "werewolf serum", turning them into humanoid wolves under her control. At that point, her antics at the prison caught the attention of Captain America, who investigated with his partner, Bucky. Although she managed to inject her serum into the Captain, he fought off her pheromone influence to lead a "werewolf revolt" while Bucky personally fought Nightshade and procured the antidote, reverting the Captain to normal. In a move that could only be called a childish temper tantrum, Nightshade ordered her werewolves to commit mass suicide by plunging over Ryker's outer walls onto the rocks just off its shore, following them over the side soon after. Nightshade turned up not long after in Chicago, where she tried to appeal to the local adventurer, Iron Fist, to help her become 'Queen of the U.S.', expecting him to choose her over his current girlfriend, Misty Knight, when Nightshade used her genius to hack into and override Knight's cybernetic prosthetic arm. Upset that he spurned her, she attempted to blow up the city, but was stopped and arrested.
