Gizmo (voiced by Laurent Tom) is a supergenius criminal and a member of the H.I.V.E. Five. He has an extensive arsenal of high-tech weapons, and a very nasty bratty attitude. Gizmo was often seen with Jinx and Mammoth. Gizmo and the other H.I.V.E. Five joined the Brotherhood of Evil to take down the Titans, but ended up being frozen at the final battle.
