If you have superpowers, you are more powerful than almost all weapons. So you fight with you as the weapon, because it's the most powerful you have.

Also: I presume you meant duel. Using a duet to elect your leaders has a certain charm to it...

Thanks, it should be duel. Updated accordingly. I kinda think that quantitive change in energy output will lead to qualitative change in the form of fighting. In addition, it's hard for me to relate to fist fighting among superheroes. If I were to enjoy fist fight, Legend of Fist by Jet Li is a much better alternative.
