Fan Casting Kid Icarus: Uprising

Twenty-five years after the first game, the Goddess of Darkness, Medusa, resurrects and sets out to conquer the world. In response, Palutena sends Pit on missions to destroy Medusa's forces, and he fights her returning commanders Twinbellows, Hewdraw, Pandora, and Thanatos, as well as the new commander Dark Lord Gaol with help from a human mercenary named Magnus. In the battle with her, Pandora uses a magical mirror that spawns a doppelgänger of Pit called Dark Pit, intending to use him as a slave. However, after Pit destroys the mirror, Dark Pit turns against Pandora, steals her powers from her corpse, and vows to kill the gods to stop the conflict, as well as Pit. After briefly tailing him, Pit eventually gains the key to the Underworld from the defeated Thanatos, then retrieves the Three Sacred Treasures from space and travels to the Underworld, where he kills Medusa with Dark Pit's assistance. Later it is revealed that Medusa was a resurrected puppet of Hades, the ruler of the Underworld who has been using the war to harvest the souls of dead humans and turn them into monsters to build his army.
