Plot Elements

 * Twenty-five years after the first film, the Goddess of Darkness Medusa mysteriously resurrects and sets out to conquer the world. In response, Pit is sent on missions by Palutena to destroy Medusa's forces.
 * During his missions, Pit fights Medusa's returning commanders Twinbellows, Hewdraw, Pandora, and Thanatos, as well as new commander Dark Lord Gaol with the help of 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, because Pit destroyed the mirror before he could be completed, Dark Pit turns against Pandora, steals her powers from her corpse, and vows to kill the gods in order to stop the conflict, as well as Pit in the belief he is the original.
 * After briefly tailing him, Pit eventually gains the key to the Underworld from the defeated Thanatos. He then retrieves the Three Sacred Treasures from space and travels to the Underworld, where with Dark Pit's brief assistance, he kills Medusa.
 * Just then, it is revealed that Medusa was a resurrected puppet of Hades, ruler of the Underworld. Hades has been using the war to harvest the souls of humans killed in it and molding them into monsters to build his army.
 * Hades spreads a rumor about a wish-granting seed guarded by a Phoenix, turning humanity against each other. This war prompts Viridi, the Goddess of Nature, to intervene; angered by both sides' desecration of Earth, Viridi and her army, the Forces of Nature, drop nuclear weapons called Reset Bombs that create artificial forests. This forces Pit and Palutena to focus on Viridi, destroying the Reset Bombs' depot and defeating her commanders Arlon and Phosphora.
 * Before Pit and Palutena can defeat Viridi, the deities' ongoing battles prompt a hive mind alien race called the Aurum to invade Earth for its resources.
 * Assisted by the sun god, Pyrrhon, Pit and the deities reluctantly unite against the threat. In the final siege against the source, the Aurum Brain, Pyrrhon betrays the deities and attempts to gain power by taking over the Aurum Brain, nearly killing Pit, but is taken over himself.
 * Viridi saves Pit, who defeats the Aurum Brain, and Pyrrhon takes them away from Earth.
 * Though peace is briefly restored, Pit wakes up three years later in the form of a ring. Eventually reclaiming his body with the help of Magnus, Pit learns from him and Viridi that, in his battle with Arlon, an insectoid monster called the Chaos Kin from another dimension escaped.
 * The Chaos Kin devours others' souls, allowing it to puppeteer them, and uses this to create mass destruction; its latest victim is Palutena, who under its control incapacitated Pit and sent her army against humanity, bringing them to the brink of extinction.
 * Pit is forced to ally with a somewhat-reformed Viridi to save Palutena and humanity. Unable to reach her temple due to it being guarded by a forcefield, Pit claims the Lightning Chariot that can successfully break it. After doing so, Pit infiltrates the temple. He frees Palutena of the Chaos Kin, but it steals her soul, turning her to stone.
 * Pit and Viridi follow the Chaos Kin into its dimension and are assisted by Dark Pit, who has discovered he and Pit have a symbiotic relationship. They kill the Chaos Kin and restore Palutena, but the Chaos Kin makes a desperate strike against Dark Pit.
 * Pit overuses his Power of Flight to save him, burning his wings and leaving him on the brink of death. To save him, Palutena and Viridi direct Dark Pit to a fountain, the Rewind Spring, where his wings can be restored. Pandora, who has been hiding in Dark Pit's wings, also uses the Spring to reclaim her body, but is defeated by Dark Pit, who revives Pit but loses Pandora's powers.
 * Pit attempts to destroy Hades with the Three Sacred Treasures, but Hades easily destroys them and eats Pit.
 * After escaping from Hades' insides, Pit is guided by Palutena to the home of Dyntos, God of the Forge, who fashions a mecha Great Sacred Treasure after Pit proves himself worthy in three trials.
 * Launching a fresh assault, Pit succeeds in injuring Hades, but the Great Sacred Treasure is badly damaged, leaving only its cannon intact.
 * Hades attempts to launch a massive attack on Pit and a nearby town, but Medusa, whom Hades revived again, sacrifices herself to create an opening.
 * With Palutena's and Viridi's help, Pit uses the cannon to vaporize Hades, saving humanity. As he and Dark Pit celebrate among the townspeople, he manages to talk Viridi down from another attack.
 * Post-Credits Scene: A disembodied Hades postulates he will return for the next sequel in another twenty-five years.
