The Pokémon Company International and Nintendo today revealed new information about the mysterious Pokémon Necrozma, new Z-Moves and more for the upcoming games Pokémon Ultra Sun and Pokémon Ultra Moon. After taking over the Legendary Pokémon Solgaleo in Pokémon Ultra Sun or the Legendary Pokémon Lunala in Pokémon Ultra Moon, Necrozma will become Dusk Mane Necrozma or Dawn Wings Necrozma.
Dusk Mane Necrozma
Type: Psychic/Steel
This form of Necrozma manifests when the Pokémon takes control of both the body and mind of the Legendary Pokémon Solgaleo, absorbing the light energy that pours out of it. It slices opponents with its strong claws on its four legs and it can propel itself forward by shooting black light from both sides of its chest. Dusk Mane Necrozma’s high Attack stat greatly exceeds that of Solgaleo.
Dawn Wings Necrozma
Type: Psychic/Ghost
This form of Necrozma manifests when the Pokémon takes control of the Legendary Pokémon Lunala, stealing its light energy by force. Dawn Wings Necrozma accelerates by shooting black light from its back. This Necrozma form shoots energy that glows darkly from the black parts of its wings. By taking Lunala into itself, Necrozma’s Sp. Atk stat gets even higher.
