Better Arch-Enemies
Which characters would benefit from a better arch-enemy? Or who would you rather see as an arch-enemy pair?
Some of my examples:
Hawkeye - Bullseye
Superman - Loki
Hank Pym - Lex Luthor
Punisher - Deadshot
Cap America - Deathstroke
Black Widow - Harley Quinn
Silver Surfer - Sinestro
Rocket Raccoon - Dexstar
