Poison Type Explained

Poison is one of only two types (with Steel) that hits Fairy super effectively. Defensively it resists five types, including Fighting, Bug and Fairy, but Steel types are completely immune to Poison attacks.

Against a pure Poison Pokémon, lead with Ground and Psychic moves and avoid Grass, Fighting, Poison, Bug and Fairy. Against a Poison dual type the answer changes, because the second type can cancel a weakness or stack it into a 4× hit — use the Pokémon type calculator to check any exact combination.
