The Poison type is one of the 18 Pokemon types. Poison is weak to Psychic and Ground type moves, and resist five types (Fighting, Bug, Grass, Fairy and themselves). Poison type moves are immune to Steel types since you can't poison anything organic.

Poison used to be strong against Bug and weak to Bug in Generation I, but since it has been changed. From Generation II to V, it is strong against only one type, Grass. Since the new Fairy type was introduced in Generation VI, Poison is strong against Grass and Fairy.


  • Poison types resist all three types that Dark types are weak to.
  • Poison types have an immunity to Steel type.
  • Sadly Poison is the only type that does not have a Legendary Pokemon.
