Poison (status condition)

The poison condition (PSN) (Japanese:  poison) is a non-volatile status condition found in the Pokémon games, it 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, and some Abilities. Poison and Pokémon are immune to being poisoned, making it the only non-volatile status condition to be ineffective against more than one type; however, Poison-type and Steel-type Pokémon can be poisoned by Pokémon with, and in Generation II, Steel-type Pokémon can be poisoned by. Along with the poison status, a Pokémon can also be badly poisoned (Japanese:  deadly poison); the effects are similar to 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.

Effect
The effects of poison vary between generations, but a poisoned Pokémon will take damage every turn. Prior to Generation V, outside of battle all poisoned Pokémon lose one HP every four steps the player takes. If the player's last conscious Pokémon faints this way, they will black out.

Generation I
A poisoned Pokémon will take damage equal to 1/16 of its maximum HP every turn, after it attacks, or at the end of the turn if it did not attack. If a poisoned Pokémon causes an opponent to faint, the poisoned Pokémon will not take damage that turn. Outside of battle, all poisoned Pokémon lose one HP for every four steps taken.

A badly poisoned Pokémon takes damage equal to 1/16 of its maximum HP on the first turn, after which damage increases by 1/16 each time it takes poison damage. When a badly poisoned Pokémon is affected by, switches out, or when the battle ends, its poison status becomes regular poison.

If a Pokémon badly poisoned by is also under the effect of, both types of recurrent damage will draw upon the same N value to calculate how many multiples of 1/16 of the Pokémon's HP is taken as damage, and both will increase that value. If a badly poisoned Pokémon successfully uses, it will be cured of poison, but N is not reset; if it then suffers , or poison damage, that damage will draw upon the N value, and the N value will still increase by 1 each time (however, if the Pokémon is poisoned with Toxic, the N value will be reset to 1).

Generation II
A poisoned Pokémon will take damage equal to 1/8 of its maximum HP every turn.

Bad poisoning remains at a starting amount of 1/16, and no longer interacts with other types of recurrent damage. Haze no longer affects poisoning. While Pokémon cannot be poisoned by  moves, they can be poisoned by.

Generation III
Poison damage is now taken at the end of each turn, regardless of whether a Pokémon is knocked out.

If a badly poisoned Pokémon is switched out, it will remain badly poisoned, but the counter is reset. Bad poison still reverts to regular poison after completing a battle.

Pokémon can no longer be poisoned by any moves.

Pokémon with will not take damage outside of battle.

Generation IV
Outside of battle, if a poisoned Pokémon is brought down to one HP due to poison damage, it will be cured of poison instead of fainting.

Generation V on
A poisoned Pokémon no longer receives damage outside of battle.

A poisoned Pokémon now glows purple in battle in Generation V, or continuously releases bubbles of poison from its body in Generation VI. Poisoned Pokémon take double damage from and.

In Generation V, bad poison displays with dark purple characters in the icon instead of white; in Generation VI, both icon and text change color.

Moves
The following moves may poison the target:

Other causes
A Pokémon has a 30% chance of being poisoned after making contact with a Pokémon with the Ability, and a 9% chance after making contact with a Pokémon with. has a 30% chance (20% in the Japanese versions of Pokémon Black and White) of poisoning the target when the user uses a contact move. A Pokémon can also be poisoned if it directly poisons a Pokémon with the Ability.

Moves
The following moves may badly poison the target:

Other causes
The item Toxic Orb badly poisons the holder at the end of the turn. From Generation V onward, a Pokémon can also be badly poisoned if it badly poisons a Pokémon with (prior to Generation V, Synchronize only inflicts regular poison).

Curing
Poison (including bad poison) can be cured with the use of an Antidote, Drash Berry (Generation III only) and Pecha Berry (PSNCureBerry in Generation II). In addition, like all other major status conditions, it can be cured by the items Full Heal, Rage Candy Bar, Lava Cookie, Old Gateau, Casteliacone, Lumiose Galette, Shalour Sable, Big Malasada, Full Restore,, Lum Berry (MiracleBerry in Generation II), and Sacred Ash.

The moves and  remove the poison status condition from the user, while  (unless the Pokémon has Soundproof as their Ability in Generation III and IV) and  remove it from all Pokémon in the user's party. In addition, the move shifts the poison onto its target (thereby healing the user). In Generation I only, using cures the opponent from poison.

Pokémon with will be cured upon switching out, those with the  Ability will be cured whilst it is ing. Pokémon with have a 30% chance of being cured every turn, and Pokémon with  have a 30% chance of curing their allies.

Prevention
In general, Steel- and Pokémon cannot be poisoned. However, they can be poisoned by Pokémon with the Ability. Additionally, in Generation II, the move can poison Steel-type Pokémon. If a Pokémon is poisoned while not Poison- or Steel-type (such as while affected by a or before evolving into a Poison-type or Steel-type Pokémon), it will remain poisoned.

Pokémon with the Ability cannot be poisoned. Pokémon with the Ability and  in Meteor Form are completely immune to being poisoned. Pokémon with the Ability will be protected from status conditions in. The Ability will prevent damage due to poison from being taken in battle; however, it does not prevent the damage from being taken outside of battle.

The moves and  (for grounded Pokémon) will protect the party from status conditions for five turns. A Pokémon behind a cannot be poisoned, except due to  or a held Toxic Orb.

Advantages
While poisoning and badly poisoning, like all major status conditions, have primarily negative effects, it can be advantageous to be poisoned in certain conditions. Pokémon with, , and will have their , , and  increased by 50%, respectively, if poisoned or afflicted by any other non-volatile status condition excluding  and ; however, in Generation IV, sleep will increase the Attack of Pokémon with Guts. Poisoning will increase the attack of a Pokémon with by 50%, and the base power of  is doubled (from 70 to 140) when inflicted with poison. A Pokémon with will regain 1/8th of its maximum HP at the end of each turn instead of taking damage. When capturing Pokémon, the poison status also adds a 1.5× multiplier to the catch rate of any given Pokémon.

In competitive battling in Generation I, as Pokémon were not healed before link battles in the handheld games, players would often enter battles with their Pokémon already poisoned, as it prevented them from being affected by other more harmful status conditions; also, poison only inflicted 1/16 of the Pokémon's total HP as damage each turn rather than 1/8 as it does from Generation II onward. This tactic was not viable in the Pokémon Stadium series, as Pokémon were restored to full health before battle in these games.

Other in-game effects
If a poisoned Pokémon gains the Ability through the use of,  or another method, the poison or bad poison status will be removed.

In, when the player is inside the Battle Pyramid, the types of Pokémon encountered on each floor follow a set of categories, on the second floor the player will encounter Pokémon that poison as their main tactic.

In the Generation IV games,, , at the Battle Arcade, one of the effects caused by the roulette is causing the poison status; Pokémon that would normally be immune to poison are unaffected. The poison will last for a single battle.

If a Pokémon has and hits a poisoned target, it will score a critical hit.

Pokémon Mystery Dungeon
Like the main games, Pokémon Mystery Dungeon also features both normal poisoning as well as bad poisoning. When a Pokémon is poisoned, it takes damage every ten turns and is also prevented from regenerating HP. Poison does not disappear over turns. When a Pokémon is badly poisoned, it takes damage every two turns and also prevents regenerating HP. Similar to the main games, the poison conditions do not disappear over turns but can be healed with certain moves or items, and by going to the next floor.

Poison and bad poison (Poisoned and Badly Poisoned when inflicted in-game) are negative statuses in the. When a Pokémon is Poisoned, its HP will gradually drain at a rate determined by the Power of the Pokémon that inflicted it for ten seconds. However, if the affected Pokémon is controlled by a player, moving around will make the condition wear off faster, with the minimum duration depending roughly on the Pokémon's Speed. While Poisoned, purple bubbles emanate from around the affected Pokémon's head. The effects under Badly Poisoned are similar, but the rate at which HP is depleted gradually increases while the status lasts and purple smoke emanates from the Pokémon's head instead of bubbles. Though most negative statuses will replace one another if one is inflicted while another is present, Poisoned cannot replace Badly Poisoned (though Badly Poisoned will replace Poisoned).

No types are immune to poison or bad poison, but Pokémon with the Poison Boost or Steady Special Traits cannot be poisoned or badly poisoned, and those with the Reflector Trait will cause the user of the poison-inflicting move to become poisoned or badly poisoned instead if hit by one.

Pokémon Conquest
Like the main series, a Pokémon inflicted with poison is protected from other status conditions and does not wear off over time. Normal poison can be inflicted by attacks, abilities, or by a Pokémon ending their turn in a poison bog. Bad poison can only be inflicted by the effect of Poison Fang. As in the main series, Poison- and Steel-types are immune to poison. Poison can be cured through certain Warrior Skills, items, or by ending a Pokémon's turn in a hot spring or a water bucket.

Pokémon afflicted with normal poison lose 1/8th their max HP, rounded down, at the end of their side's turn, even if the poisoned Pokémon itself took no action. Pokémon afflicted with bad poisoning lose 1/16th of their max HP initially, with damage increasing by 1/16 at the end of their side's turn. Enemy Warriors defeated through poison damage are not treated as being defeated by the player, and thus cannot be recruited after the battle.

Pokémon Shuffle
In Pokémon Shuffle, a poisoned Pokémon takes 50% more damage from Pokémon.

Poison can be inflicted by Pokémon with the Poison Skill.

Poison, Ground, Rock, Ghost, and Pokémon are immune to poison.
