Biography
At some point at time, Lex Luthor became aware of Pamela, as well as her identity as Poison Ivy. Lex wrote in one of his journals that Pamela had began to exude a pheromone that had the ability to mind control others. Lex intended to take a sample of this pheromone in an attempt to mind control Superman. Supergirl learnt of this when she found Lex's journal in his prison cell at Stryker's Island.
