Poison

Poison is a hazard that takes the form of a reddish-purple or turquoise gas, in and  respectively, that is fatal to Pikmin that are not White Pikmin: they begin choking if the top of their stem is engulfed by poison gas. Choking Pikmin run around in a panic and, if not saved, eventually succumb and die. These Pikmin can be rescued by being whistled at. Poison gas is completely harmless to leaders, presumably because their spacesuits filter the air.

One of the White Pikmin's most notable traits is their relation to poison. White Pikmin themselves are poisonous, and if an enemy ingests one, they instantly receive some damage.

In, it mostly takes the form of purple poisonous lakes, and attacks from the Berserk Leech Hydroe. Any Pikmin that falls into a poison lake, or even Olimar himself, instantly dies.

In Pikmin 2... Again?
Poison returns in Pikmin 2... Again?. It is unchanged from its previous incarnations, retaining a reddish-purple coloration and causing affected Pikmin to flop uncontrollably along the ground, but also has a liquid form.

In Pikmin Rebirth
Poison is a recurring hazard in Pikmin Rebirth. Poison is often a thick purple gas, like in its previous appearances, but can also be in liquid form, and can be grey or green. Usually, poison, in the form of purple gas, will come from vents in the ground, forming a pervasive cloud in enclosed spaces lacking ventilation, but can also be in other forms such as poisonous sludge that impedes the movement of captains. While White Pikmin resist purple poison, all types are affected by grey poison, which decays Pikmins' maturity by one stage every few moments and is fatal to those at leaf stage maturity, and green poison instantly kills all Pikmin types, even White Pikmin. Purple poison is found in many different areas, grey poison is found in damp and humid areas, and green poison is found in caves and dry areas. White Pikmin, in particular, are poisonous themselves and can harm enemies by simply being eaten. They become even deadlier if they infused with poison to become the highly-corrosive Cyanide Pikmin, which are resistant to all three types of poison, and, upon dying, leave behind a toxic puddle that can harm enemies.

In Pikmin: Shipwrecked Stargazers
In Pikmin: Shipwrecked Stargazers, poison comes in two forms: a gas, which is a thick, velvet-colored cloud, and a liquid, referred to as venom. Venom is a translucent, mucusy liquid with a faint purple tint that functions similarly to its gas form but can also coat surfaces. White Pikmin possess immunities to both forms of poison, and can remove puddles of venom on the ground.

New sources of poison include:
 * a member of the cheragor family that spits globs of venom at certain phases of its fight.
 * a male member of the vexpa family that can shoot highly concentrated streams of venom from its stinger.
 * a member of the pyscute family that can shoot venom from its outwardly curved fangs.

In addition to this, the Smoky Progg's trail is classified as a very potent form of poison, rather than gloom, due to this game being developed before was released in full.

In Pikmin: Spark
Poison appears in Pikmin: Spark. Poison can only be neutralized by White Pikmin as other types are be scattered by it. Three types of poison exist: pink poison simply endangers inapt Pikmin exposed to it, green poison kills them, and black poison, which is exclusive to Challenge Mode, instantly kills all Pikmin exposed to it, even White Pikmin.

All existing poison-related obstacles return, alongside new ones:
 * Poison gas: poison smog that White Pikmin can breathe like Blue Pikmin can water. Green gas damages exposed captains very slowly over time.
 * Poison mushroom: fungi that burst into poison when neared.
 * Purple sludge: a waxy substance that is toxic to Pikmin. White Pikmin can destroy it.
 * Toxic sprinkler: a device that scatters poisonous liquid all around itself in a circle. The large variant can not be destroyed.
 * Toxic pod: vegetation that spews poisonous gas as a defensive maneuver.

In Pikmin: Wide World
Poison is a common hazard appearing in Pikmin: Wide World, in the forms of a purple-colored gas or liquid. White Pikmin are resistant to it, and poison most enemies that eat them. How much damage a White Pikmin's poison can inflict upon an enemy depends on its size and if the involved enemy utilizes poison. Other Pikmin that touch poison will begin flailing around, choking, with a cloud of it engulfing the end of their stem, but they can be whistled to save them. Leaders are unaffected by poison because of their suits' filtration systems. Poison can be utilized by leaders by using a dose of ultra-toxic spray, which can be gained by collecting enough of a Spiny Spiderwort's berries or by finding a drop of it. Upon use, a large cloud of poison will appear around the leader that used the spray, and it will linger there for some time before dissipating. This cloud deters most enemies, harming those passing through it, but it can also endanger any Pikmin except White Pikmin. However, enemies that utilize poison may pass through without harm, and some enemies, such as the Stubborn Bulblon, do not care if they are hurt by the poison cloud. Smoke bomb rocks, upon activation, emit poison gas for some time before becoming inert. It is highly recommended that White Pikmin carry them and that the smoke bomb rocks they are carrying be used to keep enemies at bay. Gas pipes are the most common poison-related hazard and can be found within bramble gates to form poison bramble gates, much like how fire geysers can be found within bramble gates to form fire bramble gates.

Berry Bloysters, in water, can release a short-lasting cloud of poison to defend themselves with. Black Spectralids feverishly flap their wings to scatter poisonous black scales when threatened. Doodlebugs release flatulence, leaving a small, short-lasting cloud of poison at their previous location. Mouthy Mimitators can spew from their mouth a toxic substance that acts as both acid and poison, meaning no Pikmin is resistant to it. Munge Dweevils can release a cloud of poison gas in self-defense. Noxious Mitites are perpetually cloaked in poison gas. Poisonous Blowhogs blow poison gas onto Pikmin and leaders, pushing them around and poisoning them. Putrid Bulbears are perpetually engulfed by a cloud of poison gas and can also exhale it. Sporegrubs release small clouds of poison gas at potential attackers. Spornets hover over Pikmin to sprinkle poison dust onto them. Swarming Burrow-nit Larvae can produce small puffs of poison gas to ward off attackers, although, unlike in Pikmin 2, ordinary Burrow-nit Larvae cannot. Tropical Bloysters are poisonous to the touch, but their bulbs can be attacked by any Pikmin type. Venomous Scornets can poison Pikmin by stinging them. The Ancient Bulblax, though not itself poisonous, has a few Spiny Spiderworts growing on its back, its berries being knocked loose every step the creature takes and bursting upon impact with the ground. Daddy Long Legs' have poisonous spores stuck in the hairs protecting their joints. The Grimacing Cremblub exhales poison, which it does passively or while producing a vocalization. Heir Bulblaxes can exhale poison. The Hydroe Host, being a heavily-mutated Mouthy Mimitator, can spew the same toxic substance as the ordinary ones do. Jazzy Crawmads, from a distance, can squirt a line of liquid poison at its prey. The Noxious Crawbster is perpetually cloaked in poison gas. The Smoky Progg is unique in that the poison emitted from the base of its body can instantly kill even White Pikmin. Lastly, the Titan Dweevil may turn purple before releasing a massive cloud of poison, as one of its four hazard-based attacks.

Although ink, such as that produced by Inky Waddlepi, Sputtlefish, and Mesmerizing Sputtlefish, may appear to be a form of poison, it is completely harmless and only a source of panic. Similarly, the glowing pink particles scattered by Twilight Spectralids and Vehemoth Phosbats are completely harmless and have the same effects. Both Jackwigs and Shearpions may sting Pikmin they are attacking, but neither inject poison into them. Withering Blowhogs and Withering Blowlets blow what may be assumed to be poison, but their breath only reduces a Pikmin's maturity to the leaf stage.
