Godzilla is a radioactive reptile.
Godzilla like is a T-rex with the blades of a stegosaurus. He was a baby lizard on an island where the atomic bomb exploded. He was still inside his egg, which was the nonly one that survived.
Godzilla was also harmless like King Kong. He attacked ships because he wanted the fish inside. The reason why he came into the city was because he wanted the fish at the nearby fish market. He caused lots of damage only because he was big and mad at the navy for sending airplanes and tanks after him. Bad day!
