Suggested by Destroyer Hao is a being of near limitless cosmic abilities. He has a solid Oversoul and can try to keep Goku back with his ranged moves. Still, there isn’t much he can do against a Super Saiyan god. Goku’s Kamehameha alone would end the fight rather quickly. Goku’s one of the strongest beings in all of media, trying to stop him is like trying to stop an Earthquake with a spoon. There are less than a handful of characters in all of media who can hope to beat him. Goku wins.
