ONLY REPLY TO THOSE WHO HAVE READ PERCY JACKSON/HEROES OF OLYMPUS/TRIALS OF APOLLO.
Battle setting: A riverbank
Weapons: Katara: pouch filled with water, Percy: Riptide
State: Bloodlust
I am looking for a good explanation, I am not pressuring you, but don't just say "Katara" or "Percy". Give me examples of why your contestant would prevail.
PS. I didn't do a poll because this is the Avatar wiki so people who have not read Percy Jackson will obviously say Katara and that's not fair.
