Ok one it's a remake. Two I want to change Godzilla's energy to be like a magic energy. Three Godzilla can turn human and has a crest in him. Ok so basically Godzilla goes to a anti war because he face war and almost died. So here's the story.

Fódlan the land of peace and unknown history but it was then there was a history of a legendary creature. Godzilla the kaiju creature who then is on a rampage. Godzilla who is an unknown dinosaur who survive from millions of years that live on the islands of Brigid. It was then Godzilla met an army who was part of the war. It wound him so they made him as their pet with their crest but died. It was then Godzilla was then revived by the crest and as then mutated his body into a 50meter monster. Godzilla then rules the seas and he began his terror up the surface. It was then people say that Godzilla is like some god that they worship. It was then Godzilla is the destroyer of the land. What will Godzilla do and how will Rhea defeat this abomination.
