Three new graduates from the H.I.V.E. Academy, Gizmo, Jinx, and Mammoth, are hired by Slade to ambush the Titans. The Titans try to stop them, but Robin is lost during the fight and Titans Tower is taken over by the H.I.V.E. students.

When the H.I.V.E. shows up causing havoc, the Titans get straight to the job. Unfortunatley, they escape, but Robin was able to plant a locator device onto Jynx just in time. The Titans send Cyborg - disguised as a strong man known as ""Stone"" - to infilitrate the H.I.V.E. academy and find out what they're up to.
