Shortly after the reveal of Lycanroc's new Dusk Form coming to Pokemon Ultra Sun & Ultra Moon, a number of new features of the games were also shown in a massive release. One of these came with the news of brand new Exclusive Z-Moves coming to a number of Pokemon within Ultra Sun & Ultra Moon, starting with none other than Kommo-o.
Kommo-o new Z-Move will be called Clangorous Soulblaze, a Dragon Type Attack that will do massive damage to all opponents of the field. What makes Clangorous Soulblaze so unique (and incredible) is that fact that it also raises ALL of Kommo-o's Stats by one level. Because of this new Z-Move, Kommo-o goes from a relatively mediocre Pokemon to that of a god among us.
