Suggested by Sonic Both of these fighters are pretty similar when it comes to movesets. They each possess super strength and telepathic abilities. However, Ultra Humanite is Grodd’s superior in both areas. In physical strength he was able to take on heavyweights like Power Girl and Superman. I don’t see Grodd matching that level of ability anytime soon. Humanite’s a lot stronger than you would think and that’s likely because he simply isn’t very popular. Ultra Humanite wins.
Update 2/12/2022 with the Flash’s speed from the comics, Gorilla Grodd definitely wins this. Gorilla Grodd wins.
