Jet Jaguar fought alongside Godzilla in Godzilla vs. Megalon. The best description of him is that he's a robot built by a child that can change sizes and fight. Well that sounds just plain silly. He also has a weird look to him, but that's because he was actually designed by a 10 (or younger, idk) year old for a design a character contest. So that's why Jet Jaguar's on the list. He's just a silly monster. Sorry to any Jet Jaguar fans!
