Kommo O

Kommo-o is an excellent bulky mixed attacker in the 1v1 metagame, with a powerful offensive typing in Dragon / Fighting and the ability to beat common Pokemon such as Mega Gyarados, Mega Lopunny, and Aegislash. It also has access to the only Z-Move that deals damage and boosts all stats, Clangorous Soulblaze, which gives it the power necessary to beat threats such as Greninja, Mega Charizard Y, and Zygarde. Kommo-o also has a somewhat rare niche of being able to beat virtually every single Sturdy Pokemon in the metagame, such as Donphan, Carracosta, and Magnezone. It only loses to Skarmory, thanks to the latter's Supersonic Skystrike. With some defensive EV investment, Kommo-o can tank several powerful attacks such as Ice Beam from Choice Specs Greninja, Air Slash from Mega Charizard Y, and Outrage from Mega Gyarados without compromising its ability to reliably overcome its other matchups. Unfortunately, its relatively poor defensive typing for the 1v1 metagame makes it quite susceptible to virtually every Fairy-type, such as Magearna, Tapu Lele, Tapu Fini, and Mega Gardevoir. Additionally, it is also unable to stand against most Dragon-types, such as Mega Charizard X and Dragonite, which can easily OHKO it with their powerful STAB attacks.
