Thor vs Silver Surfer vs Superman
There is no weakness exploitation of any kind, this means not manipulating their internal powers, no draining, no taking away hammers nor boards or anything crappy like that. This is a sheer power, defending and attacking, with all characters fighting in character but at the height of their abilities -which means they will use their full speed, skill and will use tactics with their respective powersets-. The three will fight in a secluded planet, with no bfr.
Who. Comes. On. Top?
