But actually Percy is the strongest demigod alive( he's a better swordsman and is more capable with his powers than Jason. Despite him having been trained since he was 3) And from what we've got from the series children of Poseidon are just as powerful as children of Zeus. Theseus(the 2nd greatest hero of greek myth),Bellepheron. Heck even Sciron and Chrysaor have shown inhuman skill beyond anyone in the series. And they are all children of Poseidon. Also Achilles wasn't a son of Zeus.
