Altar of the Sunne/Moone

Defeat Dusk Mane Necrozma (Ultra Sun) or Dawn Wings Necrozma (Ultra Moon) at the Altar of the Sunne/Moone. Fire, Dark, and Ghost types are recommended.

During this battle, you’ll face off against Necrozma that has fused with one of the Legendary Pokémon. If playing Ultra Sun, you will have to fight Dusk Mane Necrozma, which resembles Solgaleo. Meanwhile, Ultra Moon players will encounter Dawn Wings Necrozma, which resembles Lunala.

No matter what form Necrozma has taken, your goal is the same: to knockout Necrozma. Don’t worry about trying to capture Necrozma, because you can’t at this point in time. Compared to the Totem Pokémon previously, this battle should be easier in theory, but this is a Legendary Pokémon we’re talking about.

Dusk Mane Necrozma (Ultra Sun)

• Level: 50
• Type: Psychic/Steel
• Moves: Sunsteel Strike (Steel, ignores Ability), Morning Sun (Heal), Psycho Cut (Psychic STAB), Night Slash (Ghost)
• Weaknesses: Fire (resists Sunsteel Strike), Ground, Dark
• Incineroar is ideal: immune to Psycho Cut, resists Night Slash.

Dawn Wings Necrozma (Ultra Moon)

• Level: 50
• Type: Psychic/Ghost
• Moves: Moongeist Beam (Ghost, ignores Ability), Moonlight (Heal), Psychic (Psychic STAB), Power Gem (Rock)
• Weaknesses: Dark (4x damage, immune to Moongeist Beam and Psychic), Ghost (4x damage, but takes super-effective from Moongeist Beam)
• Normal-types can be useful due to immunity to Moongeist Beam, but need an attack.

Successfully drive off Necrozma and it’ll escape back to its home turf. Now you’re back to square one. Fortunately, all hope isn’t lost, as the Ultra Recon Squad arrive on the scene. You’ll borrow their Legendary Pokémon and use it to enter Ultra Space in search of the world that Necrozma fled to.

Your aim is to fly through the balls of energy and travel through one of the pure white warp holes. Succeed and you’ll reach Ultra Megapolis, where Necrozma can be found. If you enter a different warp hole, you’ll receive a message that Necrozma isn’t here. You must then exit this world and speak to the Ultra Recon Squad to try again.
