Byakuya vs. Vergil: Cold and aloof brothers to one of the main characters, who fight mainly through their signature supernatural swords. Both are also high-ranking members of their series' main law enforcement group.

Gilgamesh vs. Yukari: Gold-haired, red-eyed spirits who are seen as some of the most powerful characters from their series. Because of their powerful reputation, they are considered legendary, which makes them very arrogant and prideful. They're main abilities revolve around opening portals to other dimensions, which they use to fire weapons out as powerful projectiles. They both possess incredibly hax powers, which they believe makes them invincible.

I can't think of anyone else for Pain.
