Meeting of the Gods
Disclaimer: Don't own nothing of Buffy or Percy
Unknown to all but a select few, Xander Harris was no ordinary human. A fact that he would discover when he was only sixteen. During the period where he and his friends were being terrorized by Angelus, thanks to Buffy's inability to kill him.
Xander was going home when it happened. He was attacked and he lay on the street dying when a man appeared and killed his attacker, Angelus. Then the man lifted Xander up and took him...somewhere.
When Xander woke up, he saw that the man was still there, along with others. And when the man saw that Xander was awake, he began to speak. He was Zeus, God of the Sky's and King of the Gods. He then introduced the others. Poseidon, King of the Seas; Hades, God and Lord of the Dead; and Nyx, Goddess of the Night and Mother of Gods. Zeus went on to explain that Xander was their son, created when they became lovers, and as a part of all of them. He had been stolen from them when he was only a week old. The Hellmouth energies, created by Kronos had kept them from being able to find them.
Needless to say Xander was very shocked. But he still allowed them the benefit of a doubt. And once they unbound his powers he really believed them, he was their son and he was a God. The God of Destiny, Justice and Redemption. As ordained by his birth.
