Gizmo

Gizmo was created by Chris' dad, Professor Quantum, to protect the kids -- but they end up protecting him. He loves upgrades to make himself more useful and would rather stay in the lab than time travel with Superbook. A really cool feature of Gizmo is that he can change his appearance as needed.

He is the Rainbow Superbook Power Ranger. He pilots the Superbook Penguin Megazord, his superpower is guiding lights, and he represents hope and light.
