Godzilla is an ancient alpha-predator that thrived during the Permian Period, when radiation levels on the Earth's surface were much higher. After the Permian extinction, radiation levels declined and Godzilla retreated into the depths of the sea to live closer to Earth's core in order to subsist on the planet's natural geothermal radiation. Here he remained dormant for hundreds of millions of years, only surfacing on a few rare occasions in early human history and subsequently inspiring the mythologies of several cultures. Godzilla was awakened in 1954 by American and Soviet nuclear submarines reaching into the lower depths of the South Pacific Ocean, with his attacks on them leading each nation to suspect the other of being responsible for their destruction. When Godzilla's existence finally became known, the American military attempted to kill him under the pretext of testing nuclear weapons, however these attempts failed and Godzilla once again vanished into the ocean for another 60 years.
In 2014, Godzilla detected the mating calls of the M.U.T.O.s, parasitic kaiju that existed during the Permian Period, and followed them. After engaging the creatures in Honolulu and San Francisco, Godzilla, with some assistance from the US military, finally succeeded in defeating them and again returned to the ocean's depths.
