Silver Surfer vs Captain Marvel (Marvel)
The particular Captain Marvel I'm thinking about is the Genis-Vell version right before he went crazy insane-o after getting freaked out by his cosmic awareness. Although, if you want to make comparisons after he went hrough this, by all means go ahead. I just never was able to track down those issues much to my chagrin because I loved the premise. "Is too much power, too much responsibility?"
I thought this up because I really don't know. I mean, Surfer is pretty powerful... but Cap got a lot too. He's got ability to shoot around the universe, energy wielding powers on par with Surfer's destructive powers (if not energy manipulating), and cosmic awareness.
Go ahead and make it no-holds barred and the plot device is Captain Marvel is made cosmically aware that if Surfer continues to exist for one more day, he will bring about a cataclysm that destroys the universe, so he zips over to him in some remote galaxy and starts beatin on him. I'm stating this because I don't want people saying Surfer is too pacifist to get serious. Oh, and just as a monkey wrench, Rick Jones is connected to Captain Marvel and is watching this.
