Robin. Superboy. Wonder Girl. Impulse. Teen Lantern. Jinny Hex. Amethyst. They're the most dynamic young heroes in the world--or they would be, if their most recent adventure hadn't left them scattered across the Multiverse! To get back home, the members of Young Justice will have to fight their way through some of the most dangerous realities in all of creation--including one ruled by their own evil doppelgängers, the Young @#&*$^*!--and join forces with Zan and Jayna, a.k.a. the Wonder Twins, and the newly minted superhero Naomi for an all-out assault on S.T.A.R. Labs!
