Jessica Parker Kennedy

Jessica Parker Kennedy is best known for playing deranged teen Bette Sans Souci on "Smallville," the show that revamped Superman for a whole new generation. Kennedy's character is a lethal, deranged teen capable of great destruction with her super powers and is able to emit a weird forceful energy explosion at anyone who gets in her way. The character is also known as Plastique and a member of the Injustice League.

Kennedy also appeared on the MTV supernatural horror series "Valemont"--each episode is only two-and-a-half minutes long--and in 2011 earned the lead role on the CW dark fantasy program "The Secret Circle."
