265 Million Years ago, Late Permian Era

A large, ancient filter-feeding fish was dead on a beach. Dying from something, it has already attracted a scavenger. It was a graysh black and red color, with wings on its sides, folded in case danger ever approached, and with 2 mandibles. It is 61 meters high, and around 5000 tons.

This creature has flown down from the skies to feed on the dead creature. The animal dug into the hide, and began to devour the beheamoth. Little did it know, however was that an even larger predator is on the prowl. The creature sensed something huge is coming, and flies away…just as a stream line of blue ray hits the carcass. It looked down to see a larger, bipedal reptile, 106 meters in height, and 90,000 tons in weight. The alpha predator has long dorsal spines going all the way down to its tail, and crocodile like skin. The flying creature screeched in defense and the alpha predator roared in response.

The flyer flew towards the beast and stabbed it with its mandibles. The alpha predator roared in annoyance, and tried to shake it off. When the flyer slid down to near its mouth, the alpha predator bit onto the creature's wing, and started shaking it from side to side. The bite force tore off a chunk of the wing from the flyer. The flyer screeched in pain as it tumbled to the ground. The alpha predator roared and advanced towards the downed prey. Little did they know however, was that their world will soon change forever.

Deep in outer space, several large asteroids were approaching the planet. There were about 3 of them, and the largest is around 2 times larger than even the asteroid that killed the dinosaurs almost 200 million years later.

The largest asteroid was the first to enter the atmosphere. As the flyer screeched in futile protest at the alpha predator, the Alpha predator felt something strange going on. It looked up, just in time to see a humongous ball of rock entering the atmosphere. The 2 creatures barely had enough time to react, as the ball of rock slammed into the very spot where they were fighting. The other asteroids fell in other parts of the world, each sending billions of fragments from each blast tumbling down.

This event is now known as the Permian Extinction. Far more devastating than any extinction before, each of these impacts have caused a chain reaction; super volcanoes erupted, covering the atmosphere with toxic chemicals, the eruptions creating massive earthquakes, causing release of toxic chemicals such as C02 and Methane. This killed off over 95% of all living things combined in this era alone.

During this time, radiation filled the atmosphere, creating giant creatures such as the flyer and Alpha Predator. But due to the extinction, the radiation levels decreased, causing the majority of creatures that depend on it for survival to perish. There are VERY few survivors however, that have adapted to the radiation-less environment and either swam to the deep ocean or bury themselves near the Earth's core, where there is an infinite amount of Radiation emitting from the core. Miraculously, the Alpha Predator, the last of its kind, and who survives the impact on point blank range, also adapts and buries himself in the deepest part of the ocean.

From there, the Alpha Predator remains dormant, feeding on the radiation unless some other monsters rose from the depths for unknown reasons. That's when he'll rise and kill whatever is a threat to his territory and to his title as Alpha Predator. Survivng well into Ice Age times, he has been seen by many prehistoric people, and at the dawn of civilization, has sometimes been worshipped as a god.

They call him, Gojira.
