Update: This week’s Nintendo Direct has shared more details, in that the exclusive Z-Move is Splintered Stormshards. The Rock-type Z-Move can remove effects from the terrain, and can be used by a Lycanroc that knows the move Stone Edge and is holding the special Z-Crystal Lycanium Z.
Original Story: CoroCoro Comic has revealed that Lycanroc will soon be able to unleash a special Z-Move called Radial Edge Storm in Pokémon Ultra Sun and Pokémon Ultra Moon.
Serebii reports that, to use it, Lycanroc will be required to know the move Stone Edge, and that the Z-Move’s secondary effect will remove any active terrain effects.
This will be available to all Lycanroc forms, whether that be Midday Form, Midnight Form or the recently revealed Dusk Form. The monthly manga magazine has also shared that any Rockruff with the ability Own Tempo can evolve into Dusk Form between 17:00 and 17:59 at Level 25, such as the Puppy Pokémon that will be distributed at launch.
Pokémon Ultra Sun and Pokémon Ultra Moon will release exclusively for Nintendo 3DS worldwide on November 17th.
