✒ Percy Jackson did it in the best ways possible! Riptide...! I remember exactly what Chiron said... " Percy, I've been looking for the person who was a daughter or son of Poseidon for over 50 years! Percy, just be careful and don't die, ok? Your mother told me to promise to keep you safe, and if I don't... Well, I might be sued... AS A CENTAUR!" I think he said something like that!
Harry also: saved the sorcerers stone, can speak parsletong, defeated tom riddle and a basilisk, saved Sirius and buckbeak, survived the triwizard tournament, survived a Voldemort attack, delt with the prophecy, watched loads of people die, survived and won the battle of hogwarts. So yeah Harry's the best.
