History: An atomic bomb test in 1953 woke up a dinosaur that was stuck in the ice for over 100 million years. It moved down the coastline attacking ships and a lighthouse, and made it’s way to New York City. It came ashore and wondered around, eating people when hungry. Because of he is a carrier of a disease, normal killing wouldn't work, so he was shot with a radioactive isotope while attacking the Coney Island Cyclone roller caster, which destroyed it's diseased tissue.
Fighting Power:
***It is one of the few American monsters that had an animal battle. In one scene, he briefly fought in a battle between an octopus and a shark. No actually fight happened, so it is tough to tell how he would fight. Other than the obvious, he can also whip his tail quite good, as shown in one scene. He appears to be a killer without a cause, showing he has a lot of killer instinct. However, he appears somewhat basic.
