The Poison condition (PSN) is a non-volatile status condition found in the Pokémon games that causes a Pokémon to lose HP at the end of every turn, as well as outside of battle prior to Generation V. It can be caused by several moves most of which are Poison-type, and some Abilities. Poison and Steel-type Pokémon are immune to being poisoned, making it the only non-volatile status condition to be ineffective against more than one type.
Along with the poison status, a Pokémon can also be badly poisoned. The effects are similar to regular poison but instead of having a set amount of damage dealt each turn, badly poisoned Pokémon will receive increasing amounts of damage each turn. The label for a Pokémon that is badly poisoned has light purple text from Generation V on, rather than the white text of standard poisoning.
