Cosmoem
Say it: CO-smoe-m
Kids summary (simpler)Tap to expand
Cosmoem is the Protostar Pokémon — Psychic middle stage between Cosmog and Solgaleo or Lunala. In Pokémon GO it only knows Splash and Struggle — not a battler. Psychic typing still takes Bug, Ghost, and Dark damage. Evolve Cosmog to Cosmoem, then finish to Solgaleo or Lunala when the research allows.
Say it: CO-smoe-m
Cosmoem (#790) is a Psychic Pokémon in Pokémon GO — the middle evolution of Cosmog toward Solgaleo or Lunala. Trainers never power Cosmoem for raids; its Game Master pool is Splash + Struggle only. Against Cosmoem, lead with Bug, Ghost, or Dark. Stats below use our Game Master snapshot — the real investment is Solgaleo or Lunala.

Pokédex notes
Cosmoem is a Psychic-type Pokémon in Pokémon GO. National Dex #0790. Legendaries shine in Master League and 5-star raids when IVs and moves align.
Where in GO: Legendary raids, research breakthroughs, and GO Tour events
Invest tip: Do not TM or power Cosmoem. Keep it tagged for Solgaleo/Lunala evolution when available. Shadow Cosmoem (if present) follows the same rule — evolve to the legendary final form.
