Kommo-o's exclusive Z-move actually looks like it kicks huge butt! It basically pulls off a Z-Celebrate (Attack, Special Attack, Defence, Special Defence, and Speed all go up +1 stage) and an attack at the same time. I suspect Kommo-o will move up one tier thanks to this Z-move (but since stuff like Z-Conversion Porygon-Z only hit UU to BL, I suspect Kommo-o may end up in the same place).
I suspect it'll be a Dragon-type special attack, but the only proof I have that it's a Dragon attack is that it was super-effective on a Flying Dragon (Salamence) and a Ground Dragon (Garchomp) (note that this proves that it isn't a Fighting-type attack), and I don't have proof that it's a special attack.
