Ultranecrozium Z

The Ultranecrozium Z is a Z-Crystal exclusively for Necrozma-Dusk Mane and Necrozma-Dawn Wings. It can be obtained as a drop from Ultimate boss Pokémon.

Moves this Z-Crystal can upgrade:

• Photon Geyser → Light that Burns the Sky Special: Only Ultra Necrozma can use it, if a Dawn Wings Necrozma or Dusk Mane Necrozma hold the crystal, they must Ultra Burst before they can use the Z-Move.

Moves, abilities or items like Embargo, Klutz or Trick can't make a Pokémon drop the Z-Crystal that it's holding.
