Poison-type Pokémon are some of the most feared creatures in the games. These unique and foul creatures use their poisonous attacks to weaken and ultimately defeat their opponents. They are are immune to most Normal and Fighting-type moves. This leaves them with few weaknesses, making them more difficult to take down in battle.
What’s more, many poison-type Pokémon also have access to powerful status moves, such as Toxic and Poison Sting. These moves can quickly debilitate even the strongest of foes. As a result, poison-type Pokémon are a force to be reckoned with and should be approached with caution.
Here’s our pick of the 20 best poison pokemons!
1. Garbodor

Garbodor is a Pokémon that resembles a heap of garbage spilling out of a big, ripped garbage bag. The creature’s body is rounded and bumpy, predominantly tan with blue and pink bumps. Its head looks like the ripped-open tied end of a garbage bag, and it hangs down like a cape. Garbodor is a Poison-type Pokémon introduced in Generation V.
Truthfully, Garbodor in Pokémon GO is not regarded as a powerful Pokémon, Poison-type or not. Other poison types in the game perform significantly better and have a larger CP cap. However, in PVP, Garbodor can carve its niche as the Pokémon of choice because PvP leagues restrict maximum CP.
In Pokémon Sword and Shield, Garbodor is one of the best Poison-type Pokémon thanks to its practical bulk. It is extremely helpful in defensive lineups, and its power enables it to forcibly circumvent Xatu. Garbodor is one of the most dependable setters in the game.
2. Skuntank

Skuntank is a medium-sized mammalian Pokémon with a cat-like face that resembles a skunk. It has tan and purple striped spikey fur. On Skuntank’s face, the whiskers that were present during its pre-evolution have either disappeared or have been replaced by hairy purple tufts. Skuntank is a dual-type Poison/Dark Pokémon introduced in Generation IV.
In Pokémon Brilliant Diamond / Shining Pearl, despite its weakness in certain types, Skuntank hits rather well with moves like Flamethrower and Sucker Punch. These are some of its most potent attacks, along with Belch. Skuntank may be effective against a diverse group of Pokémon thanks to its range of move types due to its dual typing with Dark.
3. Gengar

Gengar is a dark purple Pokémon with a rather rounded body. It features pointed ears, large ears, and a mouth that is usually twisted into a menacing grin.
Gengar is a dual-type Ghost/Poison Pokémon and one of the original Pokémon belonging to Generation I.
Gengar has been consistently top-tier since the days of Pokémon Red and Blue. It has excellent Special Attack and Speed and a large and varied move pool. It can be an all-out attacker or a utility player that cripples its opponents with status effects and other nasty surprises.
In Pokémon Legends: Arceus, Gengar has the potential to be a strong addition to a squad, so players will want to equip it with the best moveset possible.
4. Weezing

Weezing is a purple-colored Pokémon that has two sphere-shaped heads that are joined by a thin tube, with another sphere in the middle. The heads vary in size and appearance. Weezing is another OG Poison-type Pokémon introduced in Generation I.
Weezing is one of the more defensive Pokémon in the game; thanks to its ability, it is usually only vulnerable to Psychic and resists Grass, Fighting, Poison, Bug, and Fairy while being immune to Ground. It is also one of the more defensive Pokémon in the game.
In Pokémon Sword, the Galarian Weezing is a hulking beast. It has an excellent defense, so you can use that and turn it into a reliable physical tank by giving it maximum HP, Defense EVs, and a Bold personality. You can get HP back using Black Sludge every turn.
In Pokémon Red, Blue, and Yellow, Weezing is most effective against Grass-type enemies, but it can also be quite powerful against Fighting-type enemies. Bringing in a Psychic or Ground Pokémon is your greatest option if you ever face up against Weezing.
5. Venomoth

The moth-like insect Pokémon Venomoth has a body that is of various colors but predominantly purple. It has a short mandible, round, bright blue eyes, a light purple head and thorax, and a three-pointed crest on the head.
Venomoth is a dual-type Bug/Poison Pokémon introduced in Generation I. It evolves from Venonat starting at level 31.
In Pokémon GO, Venomoth has a couple of nice moveset choices, but nothing noteworthy. However, Venomoth may be a nightmare when facing a Pokémon it has an edge against that doesn’t have a sub-type that covers its weakness, easily dispatching threats like Toxicroak, Wigglytuff, and Meganium.
Unfortunately, Venomoth is not available in Pokémon Sword and Shield.
Realistically, that shouldn’t come as much of a surprise that Venomoth has poor performance in competitive play. On the other hand, it is still a good Pokémon to employ for certain circumstances. Its attack and defense are awful and should be ignored, but it possesses good Special Attack and Speed stats as well as a good Special Defensive stat. With those, you can strike quickly, roughly, and effectively as well.
6. Beedrill

Beedrill, a yellow, bipedal bug Pokémon, resembles a wasp in most ways. It does not, however, have color pits, and instead has four rather than six legs. Beedrill’s head has large, red eyes, black antennae with a sharp bend in the middle, and a round, slightly pointed mouth. Beedrill is a dual-type Bug/Poison Pokémon introduced in Generation I.
When it comes to Physical attacks, Deedrills are excellent. They are excellent against Fairy-type enemies and have above-average Speed. However, like any Pokémon, Beedrill has flaws, so watch out for Fire-types in particular.
Going for Mega Beedril in Pokémon GO is worth it. The only Mega Evolved Bug and Mega Evolved Poison types that are currently available are variations of Mega Beedrill. Mega Beedrill has the greatest DPS of all Poison types, though there will soon be stronger Mega Evolved Bug varieties. Either way, it is most definitely a glass cannon.
7. Muk

Muk is a big, gummy, amorphous Pokémon formed of living purple goo. Its two tiny eyes have dark, beady pupils. Additionally, it has a huge mouth with a gray tongue and oozing threads joining its top and bottom jaws. Muk is a Poison-type Pokémon introduced in Generation I.

In Pokémon GO, with its ability to type well and key victories over Cresselia and Trevenant, Alolan Muk is a formidable opponent. The Ultra League’s enhanced mass enables Alolan Muk to dominate prolonged matches and make better use of Acid Spray’s debuff. Even though it isn’t the best fighter in the world, its high HP, amazing attack stat, and strong special defense make it a good offensive and somewhat bulky Pokémon.
Muk is a fantastic choice in Pokémon Black 2 because of its skillset and effectiveness against a good number of circumstances.
8. Arbok

The serpentine Pokémon Arbok resembles a cobra, obviously spelling cobra backward and Mortal Kombat-stylized the “c” to “k”. Arbok has numerous pointed teeth and small, pointed eyes. It has a huge hood with a face-like design just below its skull. Arbok is a Poison-type Pokémon introduced in Generation I. It is susceptible to psychic and ground attacks.
Arbok always comes up in the weakest Pokémon list. But it is only weak in more recent games. In Pokémon Fire Red, Arbok is thought to be a pretty swift and powerful character. Its abilities either give it an advantage over status effects or allow it to defeat a formidable foe. Similar to other Poison-type Pokémon, they are underappreciated despite not being frequently encountered in Nuzlockes.
Arbok is a subpar Pokémon that is never utilized in the competitive setting, but it’s a pretty good Pokémon to employ during a playthrough. Its speed isn’t all that much slower, and its base Attack stat is a respectable 85.

Additionally, it can withstand moves of the Grass-type and only takes half the regular damage from them.
For teams with high levels of attack, Naganadel is a formidable sweeper and cleaner with good coverage and potent STAB techniques. The secret to its effectiveness is Nasty Plot, which greatly increases its already powerful Special Attack and, when combined with Life Orb, threatens several common defensive Pokémon.

When compared to Steel and Ground-type Pokémon, Nihilego is entirely weak, while completely crushing Fairy and Flying-type Pokémon.
In Pokémon Sword and Shield, Nihilego is a fantastic addition to a squad that plays like Mono Rock and frequently serves as the group’s lone quick special sweeper. It may also threaten Grass-types that can easily wall its Rock-type allies thanks to its STAB’s Poison type.
13. Roserade

Roserade is a bipedal Pokémon that combines elements of roses and carnival costumes in its appearance.

In Pokémon Ruby and Sapphire, Venosaur’s grass moves were powerful and had a respectable Special Attack stat, including Hyper Beam and later Earthquake and Sludge Bomb were physical moves, not necessarily Poison. These can be taught to other Pokémon too. The strength of Venusaur is its superior Special Attack and its Grass/Poison typing.
