Cosmoem Guide
Cosmoem is a Legendary Pokemon rated C-Tier. At 400 BST, it hits hard. It excels as a balanced. Base 131 Defense stands out.
Cosmoem's biggest threats include Volcarona (Bug), Misdreavus (Ghost), and Absol (Dark), all carrying super-effective STAB moves. At base 37 Speed, Cosmoem won't outrun any of these threats so switching to a resist is usually the safer play.
Sturdy is the go-to ability for Cosmoem. It prevents being KOed from full HP, leaving 1 HP instead. It's Cosmoem's only ability.
Base 37 Speed is low. Priority moves or Trick Room are the way to go. On offense, Cosmoem is leaning toward the physical side (base 29 Attack). Defensively? Tanky enough to absorb a few hits.
Best way to handle Cosmoem: Super-effective STAB from faster Pokemon is the simplest answer. Bug, Ghost, and Dark-type attackers hit hardest.
Game Availability
First obtainable in Sun & Moon, Cosmoem has been featured in 4 titles across 4 generations. Legendary status means a single encounter per playthrough in most games.
