Don't call them sidekicks! The Justice League needs a covert team that could operate on the sly, so who better than experienced crime fighters Robin, Kid Flash and Aqualad? Together with Superboy, recently rescued from the top-secret Project Cadmus, and the crush-worthy shape-shifting alien Miss Martian, these teens are ready to stop being sidekicks and start taking down their own villains—like League of Shadows and the Joker—all on their own. But Superboy may have a secret mission of his own to complete ... destroying Superman! Based on the hit Cartoon Network series!
