Ultra Burst (Japanese: ウルトラバースト Ultra Burst) is a transformation introduced in Pokémon Ultra Sun and Ultra Moon that affects only the Legendary Pokémon Necrozma. It appeared only once in the core series, but it also appears in spin-off games such as Pokémon Masters EX.

Necrozma requires an overwhelming amount of light and Z-Power to undergo Ultra Burst. In the core series, it must be in either Dusk Mane or Dawn Wings form and be holding Ultranecrozium Z to undergo the transformation.

History

Background

Ultra Burst is Necrozma's method of returning to its original, Ultra form. Many years prior to the events of Pokémon Ultra Sun and Ultra Moon, Necrozma was always in this form, offering its light to many worlds, including the one of the Alola region. This light became the Z-Power and aura found in Totem Pokémon and Z-Moves. Necrozma was heavily injured by the Ultra Recon Squad's ancestors who attempted to steal its light;, transforming it into a black crystalline shape that it is currently known as. It can revert to its true appearance when it has absorbed an overwhelming amount of light energy. It can get this energy from Solgaleo or Lunala and by absorbing Z-Power into its system.

Pokémon Ultra Sun and Ultra Moon

After the events of Lusamine using Nebby's power at Aether Paradise and leaving into Ultra Space with Guzma, Lillie and the player summon the Legendary Pokémon with Alola's ritual: by evolving Nebby into Solgaleo^US/Lunala^UM. They're interrupted by an Ultra Wormhole appearing, in which Guzma and Lusamina are thrown out of. Lusamine warns Lillie to stay away from the monster, with Necrozma reaching through the Ultra Wormhole and making its way into Alola. Nebby takes action and fights against Necrozma, resulting in its defeat. Necrozma pins down Nebby and absorbs its light, transforming into Dusk Mane^US/Dawn Wings^UM Necrozma. With light being drawn from Alola, Poni Island is covered in darkness. In the process, it escaped into Ultra Megalopolis, taking back the light it once claimed as its own and using Nebby's light to use Ultra Burst to become Ultra Necrozma. Necrozma appears to have undergone Ultra Burst without the use of an Ultranecrozium Z in its match against the player.

Gameplay

In order to undergo Ultra Burst, Necrozma needs to be in either its Dusk Mane or Dawn Wings form and hold an Ultranecrozium Z. Once the conditions are met, the player can select the Ultra Burst button on the move selection screen in battle in order to activate the transformation. This button appears in the same place as the Z-Move and Mega Evolution buttons would. After at least one turn has passed since Ultra Burst was used, Ultra Necrozma may use its signature Z-Move Light That Burns the Sky, provided it knows the move Photon Geyser.

Ultra Burst may only be activated once per battle, even if the player has multiple Necrozma holding Ultranecrozium Z. If Ultra Necrozma faints in battle, it will revert to its prior form and cannot activate Ultra Burst again for the rest of the battle, even if it is revived.

Pokémon Masters EX

Sygna Suit Lusamine is the only Pokémon Trainer to use Ultra Burst. Unlike Mega Evolution, Ultra Burst results in a 1.2× multiplier to five stats instead of the usual two when Mega Evolving. Dusk Mane Necrozma becomes Ultra Necrozma once it uses the sync move Loving Light That Burns the Sky, and it stays like that until the end of the battle.

In animation

Pokémon the Series

Pokémon the Series: Sun & Moon

Ultra Burst was featured in Securing the Future!, where Necrozma absorbed enough Ultra Aura from Z-Moves and the people of Alola, allowing it regain its original form, Ultra Necrozma.

In the manga

Pokémon Adventures

Sun, Moon, Ultra Sun & Ultra Moon arc

Ultra Burst was featured in Transcend!! Ultra Necrozma!, where Necrozma absorbed the Ultranecrozium Z carried by Dulse, allowing it to transform into Ultra Necrozma.

In the TCG

Ultra Necrozma is an Ultra Necrozma. But it doesn't have a state where it is only a Dawn Wings or Dusk Mane Necrozma; as a Basic Pokémon it just enters play from the hand. Mind the Ultra Burst Ability: even though it can be played at any point it is unable to attack until late in the game.

Ultra Burst, as in the act of becoming Ultra Necrozma, is not featured in the Pokémon Trading Card Game. Necrozma is described as changing form and even absorbing another Legendary Pokémon.^[1]^[2] In the game proper, however, Ultra Necrozma cards are Basic Pokémon with no special rules relating to the concept of Ultra Burst.

Ultra Burst is the Ability of Ultra Necrozma (Cosmic Eclipse 164), which does reflect a mid-battle form change by preventing it from attacking until the opponent has two or fewer Prize cards remaining. This generally reflects a "late in the game" timeframe.

Shining Burst, the attack of Ultra Necrozma (SM Promo 165), may be related to Ultra Burst.
