Percy, Frank and Leo left Camp Half-Blood. They needed time away from everyone. Annabeth and Percy just broke up, Hazel dumped Frank, and Leo just came back from the dead, just to find everyone hated him. So, they left, and joined a team called Young Justice. They've been there for three years Martian Manhunter took Frank under his wing, and he found out a thing that he didn't know he could do. Percy and Kaldur got along very well. Leo feels like an outcast... Like always. They didn't want to go back to camp. They liked it in the mountain. Frank had teammates that were almost all his age. Percy had someone to swim with. No one at camp would swim with him because he would out swim them. Leo liked it because he was the only one with fire powers and that made him unique, so he was happy, too. Plus he learned he was a valuable member of the team.
