Suggested by Destroyer Space Godzilla is definitely a powerful Kaiju. In fact it wouldn’t be a bluff to say that he is probably one of the strongest Kaiju of all time. That being said, Dark Vader is still in a whole different league to be honest. Space Godzilla can roar as loud as he wants, but Vader can dodge all of his attacks and use The Force at his disposal. Space G has no defense against the Lightsaber either which really doesn’t bode well for him. Dark Vader wins.
