Background Three teenage bad seeds - Gizmo, Jinx and Mammoth - were about to graduate from the Hive Academy and were looking to be employed by criminal patron Slade. But first he asked them to pass one final exam: destroy the Teen Titans. Gizmo, covered head to toe in high-tech gadgets, is a pint-sized boy-genius with a bad attitude. Mammoth is not just big for his age, this ultimate bully is big for his species. Jinx is a beautiful but arrogant witch able to cast hexes that bring her enemies the worst kind of bad luck.
The three criminals took over Titans Tower - but were ultimately defeated by the Titans. They are still trying to graduate the Hive Academy to become villains in their own right.
Gizmo often clashes with Cyborg - who provides a challenge and a threat to the diminutive high-tech genius. Gizmo also allies himself with the "Hive Five" - a mischievous group of fellow Hive Academy students. So far, their collective efforts have met with little success.In Winner Take All, Gizmo verses Cyborg in a competition to see who takes all and is the champion of games. This is the only time he uses his goggles in the whole Teen Titans series. He uses his flight wings, machine guns, and spider legs to attempt to beat Cyborg. In the end, Cyborg ends up beating Gizmo by destroying his Spider Legs.
