Godzilla, The King of the Monsters VS Gamera, The Friend of the Humans! Well when it comes down to it, Godzilla is an S class Giant Monster who can destroy buildings in seconds. One slash and that’s it. Not to mention that he has Aura Bursts and Atomic Breath. Gamera can shoot fire and spin a lot while doing it, but that’s not enough to stop Godzilla.
If you saw Final Wars you’d see it too. Godzilla is just in a class of his own. His raw power is off the charts and Gamera would have a tough time just staying alive. Godzilla is just far too dangerous. Godzilla wins.
