>>48112483I used what I liked, but here you go.
Any fairy type, He has a berry but that won't help for long, and flash cannon won't mean shit if you have any bulk, Gardivoir easily shit on him for example and you get dazzling Gleam before the fight, so you have no excuse to have nothing effective, It's fighting type, any Flying pokemon can fuck it up a fair bit, Even more so if they air slash and flinch it to death.
Salazzel can use toxic, now it's just fucked no matter what, or burn it so it can deal less damage, but is can summon scizor to take a flamethrower.
Tallonflame is in the game and can end up getting burned and have Flying stab.
You could use zygarde, but who uses him? Bitches.
Turtonator can fuck his shit with shell trap, any water type with ice beam and chance of freeze can cheese it.
He has so many ways to get fucked, you can get dragon claw if you look near the area, even the Fairy bug could probably put decent dent into it.
Just accept that Kommo-o is the worst of all the totems. Ultra Necrozma is actually way harder, struggle with Kommo-o is like struggling to fucking Toad man.
