If they're fighting in the Underworld, Tartarus, underground in general, or a cemetary, Nico would beat Percy hands-down. Now if their fighting in the desert or some other place without much water, I would say that Nico would probably win here as well. Unless Percy gets close enough to use his sword against Nico, that is. If their fighting in a creek, river, pond, lake, sea, ocean, or reletivly close to water, Nico would ALMOST always lose. Nico is still powerful and Percy is powerful, but I think it would come down to who's the better combatant (Percy), where they are fighting, and who can suprise the other (most likely Nico using shadow-travel).

So this one's hard to decide, but I think we can all agree that Percy or Nico could easily beat Thalia or Jason. (If you want me to explain why either of them could easily beat the Sky God's children, tell me)
