# Ultra Burst and Ultra Necrozma

Sources checked: September 24, 2026

In Ultra Sun and Ultra Moon, a fused Necrozma can become Ultra Necrozma through Ultra Burst. This is a temporary battle transformation after fusion, not a separately caught or stored Pokémon.

## Ultra Burst and Ultra Necrozma

Pokémon: 1

Ultra Burst can be used once per battle. Fainting or ending the battle returns Necrozma to its fused form; Ultra Necrozma cannot occupy a HOME box.

Ultra Necrozma is Psychic/Dragon with Neuroforce, which strengthens super-effective attacks. After the transformation turn, knowing Photon Geyser allows its signature Z-Move on a later turn. Ultra Burst and that attack are distinct actions.
