Koffing

Say it: KOFF-ing

Kids summary (simpler)Tap to expand

Koffing is the Poison Gas Pokémon — Poison before Weezing (and Galarian Weezing). In Pokémon GO it is usually candy on the way to Weezing — not a finished raid attacker. Poison helps against Grass and Fairy; Ground and Psychic hit Poison hard. Catch Koffing from the wild, eggs, or events, then evolve.

Koffing (#109) is a Poison Pokémon in Pokémon GO — the baby stage of Weezing. Trainers almost never power Koffing for raids; the value is candy and IVs for Weezing or Galarian Weezing. Against Koffing, lead with Ground or Psychic. Stats, type chart, moves, and counter picks below use our Game Master snapshot.
