He strongly dislikes the arrogance of the gods and fiercely defends the minor deities and outcasts of the mythological world. 🗡️ Powers & Combat Skills Hydrokinesis: As a son of the sea god, Percy can manipulate and generate water. He can create tidal waves, summon hurricanes, heal himself with water, breathe underwater, and remain completely dry at will.

His weapon of choice is Anaklusmos (Riptide), a cursed Celestial Bronze sword disguised as a mundane ballpoint pen that always returns to his pocket.
