Silver Surfer: Fantastic Four V Phoenix: Xmen 3
Okay so we have the silver surfer from fantastic four rise of the silver surfer with his board vs Phoenix from x men 3 the last stand. Now we all know they messed up the phoenix with the movie to how she is in the comics. But I'm just basing it on that version and the same with the silver surfer as well. If you want to use a setting then maybe Lake Alkaline if thats how you spell it from xmen 3 or you can choose a city whatever up to you.
