Here comes the Injustice League! In tonight's episode of Cartoon Network's Young Justice, a secret society of super villains emerges — and there's some cool voice casting on the roster. Star Trek: The Next Generation's Brent Spiner (who appeared on last night's Big Bang Theory) stars as the Joker, while Charmed vet Alyssa Milano plays Poison Ivy.
In the episode, "Revelations," a series of attacks by plant monsters around the world triggers the Justice League into action. Their teenage sidekicks — Robin, Superboy, Kid Flash, Miss Martian, etc. — want to help in the fight but are instead dispatched to take out the Injustice League. This formidable collection of classic DC Comics rogues includes (pictured, left to right) Count Vertigo, Poison Ivy, Black Adam, Wotan, Ultra-Humanite, Atomic Skull and Joker.
Young Justice airs Fridays at 6:30/5:30c on Cartoon Network.
