List of Percy Jackson and the Olympians characters
Sherman: A son of Ares. He, like Mark (another son of Ares), is mentioned by Percy in The Demigod Files in the short story Percy Jackson and the Stolen Chariot, when Percy asks Clarisse which of her brothers played a prank on her. He also may have been the one that Percy awoke from a midday nap in The Titan's Curse.
