Percy Jackson
Zeus: Zeus, the king of the Gods, has mixed feelings for Percy. He is upset over Percy's birth because it violates the pact that he, Poseidon, and Hades made after World War Two to not bear any more children, but is pleased when Percy returns his Master Bolt to him in The Lightning Thief. During the winter solstice in The Titan's Curse, Zeus votes to let Percy live, but this may have been tied to the fate of his own daughter, Thalia, as well. However, Thalia had agreed to become one of Artemis' Hunters before this, so it is possible that this may not have mattered. In spite of all of this, Zeus tells Percy that if he ever finds him in his realm (the sky), he will strike him down. After Percy fights in the battle at the end of The Last Olympian, Zeus offers Percy godhood, and therefore immortality, for saving Olympus from the Titans.
