Percy Jackson, Assassin, and Successor of Chaos [Discontinued]

Percy Jackson was dead. Betrayed by all his friends and family, even people he thought he could trust. His friends left him, his girlfriend cheated on him, his mortal family was dead, his father disowned him, and Zeus cast him out of Olympus, and both camps. Fortunately, some of the gods and goddesses took pity on him and blessed him. With nowhere to go on Earth, he decided to go travel the universe, changing his name and appearance.
Now known all over as the assassin, Ace, he is wanted by the creator of the universe himself, and many other powerful beings. He soon turns himself in for Chaos, getting bored of the universe, having explored most of it. Chaos, surprised, made him his second assassin and his successor, which has never been done before.
Soon, Chaos' brother escapes and heads for earth first. With a heavy heart, Chaos sends Ace down to help. What disasters awaits him this time on Earth? Maybe everything isn't what it seems?
