Background
Gizmo (also often referred to as "Giz" by Billy Peltzer) was an adorable, very kind Mogwai who is the pet of Billy Peltzer. He didn't seem to have a single bit of evil within him unlike some of the other Mogwais, making him an Eternal, or a Mogwai who refuses to be evil. He used to be owned by Mr. Wing until his death. Gizmo continued to live with Billy and Kate Peltzer in New York.
