Suggested by Destroyer Godzilla is the King of the Kaiju and not a fighter to be underestimated. That said, I don’t believe he will be able to take down the X Man here. Nate has considerable abilities at his disposal including energy projection and high speed flight. His abilities made him an omega level mutant and he would be able to deal serious damage to Godzilla while being way too fast to be hit in return. I don’t see any way for the Kaiju to turn this around. X Man wins.
