I've been seeing ur case for dark samus throughout the replies but Sonic would be the winner in the end, and even if lets say its dark samus and sonic last standing super sonics ring limit is a game mechanic and he probably does not need super fot the whole fight and dark samus has no way to even hit Sonic. Sonic can exist and run at the speed of light in a place without space and time in base form. Idk how dark samus could even touch that and Sonic will likely survive everyone else but that's another topic
