Godzilla is a mutated genus of Godzillasaurus from the Triassic Period, his origins are unknown location-wise, however some believed that Godzilla was a marine reptile rather than a Dinosaur before his radiated mutation state. Getting the Wiki-like description out the way, it's MY turn. In this world, Godzilla wouldn't be likely to survive if he existed as the movie variation, however, even though the guy i remixed made something that could live, i wanted to make a godzilla that looked more like from one of the movies. i also updated it to this.

Lore: a deep sea monster, discovered in the Mariana Trench. a giant dino-like creature who feed on deep sea fish, but was also capable of living on land. the scientists studied form a safe distance, do to the creature being massive, and having tough and rough jagged scale's as body armor. it's Height when standing went to about 70 feet (21.4 meters), just as tall as an Argentinosaurus. one time while they were studying this beast, they tried giving it some bait, which worked a little to well.... the monster had seen the scientist. curious, it swam up to him. once the scientist looked back and saw it was coming towared him, he started to swim back up faster, he managed to get back to the boat, but the creature had seen the boat as well. this monster was intelligent, and had a fasination in what it had seen, so it swam up and burst through the water with a mighty roar, it's lungs un-collapsing to allow it to breath in a different way than it was used to. it looked down at the scientists, who were terrified, and started the engine. but the newly discovered creature wouldn't let them escape, so it persued them. the scientists had reached an island, where they got off and started running, as it finally surfaced, stomping towards them with a loud and terrifing roar. the scientists made it back home the day after being chased, and they had decided to name the new species "Gojiopeidosaurus". they day after returning to there home land, the exact same specimen had tracked them all the way to there home, re-surfacing at the docks. it had smelled the fish that fisher man had caught, it smelled different... do to not being deep see fish. it used it's massive and powerful jaws to chomp through the fish, and then it started to wander around the city, watching as all the people run in terror, leaving big footprints in the streets. it roared, claiming tokyo as it's new territory. the scientists had met up with the government, and one solder was just conveniently watching Godzilla. which is why this specific Gojiopeidosaurus specimen was named, "Gojira", or in english, "Godzilla".
