The super-villain training academy known as H.I.V.E. Academy presents three of its finest cadets - Jinx, Mammoth, and Gizmo - for their first mission: to beat the Teen Titans. They succeeded in two attacks, in which Robin - the group's leader - goes missing in the aftermath of the first, and the second forces the Rest of the Group - Starfire, Raven, Cyborg, and Beast Boy from their home of Titan's Tower. Will they be able to take back the tower? At the end of the episode Robin finally learns of a villain named Slade, the same who was behind the events of Divide and Conquer.
