This is an epic crossover pic.



I could see Godzilla fighting Gomora in a vicious fight. I believe that Godzilla could defeat him, but Gomora is a powerful monster. He even defeated Ultraman during their first fight.



The best chance Godzilla has at winning would be to get past Gomora's powerful tail. I've seen how he uses it to beat down his opponents, and Godzilla would probably get thrashed by it as well.
