Young Justice - Training Day

"Your favorite cartoon teen heroes are back in action! The Justice League needed 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 villains--like the League of Shadows and the Joker--all on their own. But Superboy may have a secret mission of his own to complete-- destroying Superman!"--Page 4 of cover.
