If we give this Surfer the same attributes as 616 Surfer, and use the rules of the forum, where his powers and skills are used at peak performance, Surfer should win.
That's just the way it is. Surfer has too many options open to him, and they are not based on will-power, or absorbing energy from a sun, or how mad he gets.
It is just RIGHT THERE, at his command. He can pretty much do ANYTHING with matter or energy.
So, if you are going to say he is at his BEST, how exactly is Prime going to beat him?
Because, if you say Prime is at his best, you have to do the same for Surfer. If this is the case, all Prime has to utilize is his strength and fighting skills. And, Surfer can negate the Strength part with energy manipulation.
So, how does Prime overcome that? I'm just asking.
