From Bulbapedia, the community-driven Pokémon encyclopedia.
Poison (Japanese: 毒 poison) is a non-volatile status condition that causes a Pokémon to take damage over time. In the games, it is often abbreviated as PSN.
It is often caused by Poison-type moves. Poison- and Steel-type Pokémon are normally immune to being poisoned.
There is also a special kind of poison condition known as bad poison (Japanese: 猛毒 deadly poison). The amount of poison damage inflicted to a badly poisoned Pokémon increases over time.
In the core series games
In battle, a poisoned Pokémon takes damage each turn. The exact amount of damage varies between generations and depending on the type of poison.
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 (rounded down, but set to 1 HP if it would be less) on the first turn, after which damage increases by 1/16 each time it takes poison damage. The damage stops increasing when it equals 15 * floor(maximum HP / 16). When a badly poisoned Pokémon is affected by Haze, switches out, or when the battle ends, its poison status becomes regular poison.
If a Pokémon badly poisoned by Toxic is also under the effect of Leech Seed, 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 Rest, it will be cured of poison, but N is not reset; if it then suffers burn, Leech Seed 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).
A poisoned Pokémon will take damage equal to 1/8 of its maximum HP each turn.
Bad poison damage no longer interacts with other types of recurrent damage. Haze no longer affects poisoning.
While Steel-type Pokémon cannot be poisoned by Poison-type moves, they can be poisoned by Twineedle.
Poison damage is now taken at the end of each turn, regardless of whether a Pokémon faints.
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.
Steel-type Pokémon can no longer be poisoned by any moves, including Twineedle.
Generation IV onward
Poisoned Pokémon take double damage from Hex and Venoshock.
Poison- and Steel-type Pokémon can be poisoned by a Pokémon with the Ability Corrosion.
If a Dynamaxed opponent in a Max Raid Battle becomes badly poisoned, it will instantly become normal poison.
Outside of battle
Prior to Generation V, outside of battle, all poisoned Pokémon in the player's party lose one HP every four steps the player takes.
Pokémon with Immunity do not take poison damage outside of battle.
Generation I to III
Poisoned Pokémon take poison damage until they faint. If the player's last conscious Pokémon faints this way, the player blacks out.
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.
Poisoned Pokémon no longer take poison damage outside of battle.
In Generation V, a poisoned Pokémon glows purple while in battle; from Generation VI onward, a poisoned Pokémon continuously releases bubbles of poison from its body.
In Generation V, the poison status condition icon for badly poisoned Pokémon has dark purple characters instead of white; in Generation VI, both the icon and text change color.

The following moves may poison the target:
A Pokémon has a 30% chance of being poisoned after making contact with a Pokémon with the Poison Point Ability, and a 9% chance after making contact with a Pokémon with Effect Spore. Poison Touch 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 Synchronize Ability.
The following moves may badly poison the target:
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 Synchronize (prior to Generation V, Synchronize only inflicts regular poison).
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, Heal Powder, Lum Berry (MiracleBerry in Generation II), and Sacred Ash.
The moves Refresh and Rest remove the poison status condition from the user, while Heal Bell (unless the Pokémon has Soundproof as their Ability in Generation III and IV) and Aromatherapy remove it from all Pokémon in the user's party. In addition, the move Psycho Shift shifts the poison onto its target (thereby healing the user). In Generation I only, using Haze cures the opponent from poison.
Pokémon with Natural Cure will be cured upon switching out, those with the Hydration Ability will be cured whilst it is raining. Pokémon with Shed Skin have a 1/3 chance of being cured every turn, and Pokémon with Healer have a 30% chance of curing their allies.
In general, Steel- and Poison-type Pokémon cannot be poisoned. However, they can be poisoned by Pokémon with the Corrosion Ability. Additionally, in Generation II, the move Twineedle can poison Steel-type Pokémon. If a Pokémon is poisoned while not Poison- or Steel-type (such as while affected by a type-changing move or before evolving into a Poison-type or Steel-type Pokémon), it will remain poisoned.
Pokémon with the Ability Immunity cannot be poisoned. Pokémon with the Comatose Ability and Minior in Meteor Form are completely immune to being poisoned. Pokémon with the Ability Leaf Guard will be protected from status conditions in harsh sunlight. The Ability Magic Guard 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 Safeguard and Misty Terrain (for grounded Pokémon) will protect the party from status conditions for five turns. A Pokémon behind a substitute cannot be poisoned, except due to Synchronize or a held Toxic Orb.
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 Guts, Marvel Scale, and Quick Feet will have their Attack, Defense, and Speed increased by 50%, respectively, if poisoned or afflicted by any other non-volatile status condition excluding sleep and freeze; however, in Generation IV, sleep will increase the Attack of Pokémon with Guts. Poisoning will increase the attack of a Pokémon with Toxic Boost by 50%, and the base power of Facade is doubled (from 70 to 140) when inflicted with poison. A Pokémon with Poison Heal 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 Immunity through the use of Skill Swap, Trace or another method, the poison or bad poison status will be removed.
In Pokémon Emerald, 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, Pokémon Platinum, HeartGold and SoulSilver, 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 Merciless and hits a poisoned target, it will score a critical hit.
In the spin-off games
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 Rumble series. 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.
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.
In Pokémon Shuffle, a poisoned Pokémon takes 50% more damage from Poison-type Pokémon.
Poison can be inflicted by Pokémon with the Poison Skill.
Poison, Ground, Rock, Ghost, and Steel-type Pokémon are immune to poison.
In the anime
The poison status has been shown multiple times in the anime:
- In Princess vs. Princess, Jessie's Arbok proceeded to poison Yumi's Primeape by biting its fist.
- In Sharpedo Attack!, while Brock was battling a Sharpedo, it suddenly fainted. He examined it and realized that it had been poisoned by Seviper's Poison Tail. Brock did everything he could for Sharpedo, but even though he didn't have any medicine, Sharpedo's poison got cured by itself after a while.
- In Keeping In Top Forme!, Shaymin, Piplup, and Pikachu all got poisoned, Shaymin from getting exposed to some kind of poison and Pikachu and Piplup from a wild Shroomish using Poison Powder on them. Shaymin was cured by Brock, who used a Pecha Berry on it, and Pikachu and Piplup were cured by Shaymin's Aromatherapy.
- In A Real Rival Rouser!, during the Lily of the Valley Conference battle between Paul and Ash, Paul's Drapion used Toxic Spikes, which poisoned every Pokémon Ash sent out (regardless of type).

He also had his Chansey use Softboiled on Normajean's Pichu. In this episode, it seems that a fever and difficulty breathing is a side effect to the poison.
- In A Venipede Stampede!, Ash became poisoned when a wild Venipede headbutted him, activating Venipede's Poison Point. He was cured by a remedy that Cilan made. This episode shows that, not just Pokémon, but humans can also become poisoned.
- In Facing Fear with Eyes Wide Open!, Ash's Scraggy's aggressiveness towards a group of Foongus caused the Foongus to use Poison Powder in retaliation, affecting all of Ash, Iris, and Cilan's Pokémon except for Oshawott, who had been training with his Trainer and Excadrill who was not out. While Iris took care of the sick Pokémon, Ash, Oshawott, and Cilan went to a nearby pond to get Remeyo weed for Iris's poison remedy. After fending off the pond's Tympole, Ash and Cilan capture the Tympole's leader, Palpitoad, and its ally, Stunfisk, respectively, allowing them access to the herbs.
- In The Four Seasons of Sawsbuck!, a Pokémon photographer named Robert became poisoned by an Amoonguss's Poison Powder while trying to save a Deerling from a similar fate. He was cured by the Deerling's Sawsbuck friends with the help of a mysterious lake.

- In The Green, Green Grass Types of Home!, Ash's Fletchinder and Hawlucha were both poisoned by Ramos's Weepinbell's Poison Powder during Ash's Coumarine Gym battle. The poison quickly ate at their stamina, causing them both to fall to the Grass/Poison Pokémon. Frogadier managed to avoid the same fate by using its Frubbles as a mask, preventing it from inhaling the spores.
- In Mega Evolution Special IV, Alain's Charizard was poisoned by a Trainer's Mega Venusaur's Venoshock (despite the fact that Venoshock should be unable to poison its target). After the battle, Alain cured Charizard with a Pecha Berry.

- Main article: Special Conditions (TCG) → Poisoned
In the Trading Card Game, Poisoned is one of the five Special Conditions along with Asleep, Burned, Confused, and Paralyzed. When a Pokémon is Poisoned, a poison counter is placed on it and one damage counter is put on the Pokémon in between each turn. Some attacks require the player to put two, three, or even four damage counters on a Pokémon between turns, instead of the normal one. The condition can be removed by returning the affected Pokémon to the Bench or by evolving it. Unlike the Pokémon games, a Pokémon can be afflicted with Poison and Burned at the same time, along with one of Asleep, Confused, and Paralyzed.
- Poison is the only status condition to have an effect outside of battle; however, from Generation V onward, it no longer has an effect outside of battle either.
