Logline
In Young Justice, being a teenager means proving yourself over and over—to peers, parents, teachers, mentors and, ultimately, to yourself. But what if you're not just a normal teenager? What if you're a teenage super hero? Are you ready to join the ranks of the great heroes and prove you're worthy of the Justice League? That's exactly what the members of Young Justice—Robin, Aqualad, Kid Flash, Superboy, Miss Martian and Artemis—will find out, whether they have what it takes to be a proven hero. This exciting adventure series is produced by Warner Bros. Animation and based upon characters from DC Comics. Sam Register (Teen Titans, Batman: The Brave and the Bold) is the executive producer. Brandon Vietti (Batman: Under the Red Hood, The Batman) and Greg Weisman (Gargoyles, The Spectacular Spider-Man) are the producers.
