In addition to Kommo-o receiving its very own Z-Move, it has also been revealed that Lycanroc too will be gaining an Exclusive Z-Move. It's Z-Move will be called Splintered Stormshards, and all three Forms of Lycanroc (Midday, Midnight & Dusk) can use it. However, said Lycanroc must know the move of Stone Edge, as this Z-Move can only be used from it.
Splintered Stormshards is a pure Rock-Type Physical Attack, one that will do massive damage to opposing Pokemon. But what makes this Z-Move all the more incredible is its secondary effect that completely eliminates all Terrain Effects that are currently in play on the battlefield. With this move, Lycanroc will become one of the better counters to all Tapu Island Guardians.
