>>86223692Sorry, I should have elaborated.
Legendary Godzilla wasn't a Godzillasarus like the original, he lived in a time where living things consumed the radiation that the world was covered in. As the food supply ran out, he went into the ocean and went dormant, feeding on the radiation there.
In the 50's, when he surfaced, the Japanese armies bombed him, which gave him a slight power-up. The nuke didn't change him, it fed him. He has no actual animosity with humanity.
