Ultranecrozium Z
The Ultranecrozium Z (Japanese: ウルトラネクロZ Ultranecro Z) is a type of Z-Crystal introduced in Pokémon Ultra Sun and Ultra Moon. It is a Pokémon-specific Z-Crystal associated with Necrozma and allows it to transform into Ultra Necrozma after fusing with Solgaleo or Lunala, and allows it to upgrade its Photon Geyser into the special Z-Move Light That Burns the Sky when it is Ultra Necrozma.

This move effect may be in need of research. Reason: Can a Pokémon other than Necrozma that is transformed into an Ultra Necrozma use the Z-Move Light That Burns the Sky even if it does not hold an Ultranecrozium Z? You can discuss this on the talk page. |

In battle
Allows Necrozma to transform into Ultra Necrozma after using Ultra Burst and upgrades its Photon Geyser into the special Z-Move Light That Burns the Sky.
A Pokémon transformed into Ultra Necrozma cannot use any other Z-Move than Light that Burns the Sky, even if holding the appropriate Z-Crystal.
Unaffected by item negating effects (such as Embargo and Klutz). Item manipulating effects (such as Trick and Fling) cannot remove a Z-Crystal from a Pokémon.
Rayquaza cannot Mega Evolve if it holds a Z-Crystal.
Outside of battle
A held Ultranecrozium Z is automatically removed if the Pokémon is traded between players.

An image of an Ultranecrozium Z appeared in Transcend!! Ultra Necrozma!, where it was revealed to have been one of the aura-related items collected and researched by the Ultra Recon Squad.
