Kommo-o

Kommo-o is the team's premier setup sweeper. Clangorous Soul trades a chunk of HP for a boost to every stat, and Sitrus Berry immediately refunds a portion of that cost so the trade is nearly free. Soundproof blocks Snarl, Hyper Voice, and other sound-based disruption that would otherwise stop the setup cold. Modest with maxed Special Attack and heavy Speed investment turns Clanging Scales into a four-times-effective nuke against common Dragon-weak cores, while Aura Sphere never misses and covers the Steel types that resist it. Protect lets it stall out Trick Room turns before sweeping.
