Type Poison

Poison-type Pokémon have a toxic quality about them, be it because they produce venom (Ekans and Arbok for example), are poisonous plants (Bulbasaur and Oddish – these are dual Grass-and-Poison types), or have some sort of general toxicity about them (such as Koffing or Grimer). Many Poison-type moves can cause the Poison status effect, which causes the attacked Pokémon to lose hit points each turn. The Toxic or 'badly poisoned' status effect causes the amount of damage done by the poison to double each turn. Some Poison Pokémon are considered to represent a forms of pollution such as Koffing/Weezing (air pollution) and Grimer/Muk (toxic waste). Poison-types are immune to the Poisoned status effect.
