Suggested by Sonic The Wasp Woman has some decent super strength and speed so we can’t write her off right away. That being said, Percy got some massive power ups in time for the final book of the series which was sadly never adapted into a movie. He became effectively invincible in a fight so that no opponent could challenge him. The Wasp Woman would have no way to deal damage while Percy would win in a single move. The difference in their abilities is quite large at this point. Percy Jackson wins.
