Poison-type Pokémon are weak to Ground and Psychic moves in the mainline games and in Pokémon Go-style charts.

Quick Scoop: Poison Weaknesses

  • Ground-type attacks hit Poison for super-effective damage.
  • Psychic-type attacks also hit Poison for super-effective damage.

Those are the only two standard weaknesses for a pure Poison-type; dual types can add more weaknesses or resistances.

Simple example

  • A Poison-type like Weezing will take super-effective damage from Earthquake (Ground) and Psychic.
  • Against everything else, it is neutral or resistant, depending on the matchup.
