In 2054, the world goverment gave the JSDF the go ahead to drop another atomic bomb on Godzilla in an effort to rid the earth of the king of monsters.
A sole fighter jet flew over the area were Godzilla slept and it's hatch opened ... In that moment 110 years of history repeated as the mushroom cloud rose up and lanced the sky. It was a direct hit. Godzilla was down ... What happens next defies everything science had written about Kaiju. The great beast got back on its feet and started to violently twitch. It began to transform, pushing the bombs energy through out it's body and what ever was left solidified as spikes.
From that day on, Shin Godzilla went global for the next 100 years causing death and bloodshed to thousands in a mind set of pure rage. Nothing worked on Shin, not even anti nuclear shells. TGKRS (The Global Kaiju Research Society) was formed and declared Shin Godzilla as the first of the "Super Monsters" that will rise up over the next century and nearly bring on armageddon.
The JSDF state that Shin Godzilla is by far the most dangerous Godzilla to ever walk the planet as it seeks only malevolence and vengence on humanity. Other than 2 Super monsters Shin Godzilla bonds with no one. He fights & in some cases kills other monsters on sight."
