12 Strongest Poison-Type Pokémon in Pokémon GO

Poison-type Pokémon give a unique advantage in Pokémon GO that sets them apart from other types. They’re more than just strong fighters, as they can apply status effects that gradually reduce an opponent’s health over time. Including a Poison-type in your team is a smart way to weaken even the toughest enemies, allowing you to wear them down with consistent damage without directly attacking them. This tactic works particularly well in long battles, helping you outlast opponents with high health or using hit-and-run strategies.

In addition to their poison abilities, many Poison-types have other types as well, which gives them access to a range of moves and strategies. This makes it easier to create strong matchups and keeps opponents guessing, making it hard for them to counter your tactics effectively. They also resist various common attacks, making them tough and reliable team members, able to take hits while chipping away at the other side.

Toxicroak Is A Great Ally To Any Team

Even If It’s The Weakest Here

Toxicroak is a strong Poison-type Pokémon in Pokémon GO, and there are good reasons for that. It also has a Fighting-type, which gives it an advantage with different moves. Toxicroak can do more than just poison opponents; it can also hit hard with its fighting skills. For moves, Poison Jab and Sludge Bomb are solid choices. Because it has two types, Toxicroak can fit well into various teams and handle different challenges.

It can reach a maximum CP of 2674 and has a high attack stat, making it a tough competitor. If you want to beat Toxicroak, you need to know what fighting Pokémon are weak against. Toxicroak is a smart choice, thanks to its mix of offensive and defensive abilities, not just its Poison-type moves.

Drapion Is More Than A Dark-Type

It Also Deals Poison With The Best of Them

Drapion is an excellent choice if you’re looking for a Poison-type Pokémon in Pokémon GO, and it’s a strong addition to any team. It might take a while to get one, but it’s definitely worth the effort because it has powerful attacks that cause poison damage and hit really hard. Drapion comes from Sinnoh and is known for being highly poisonous, with claws strong enough to damage a car. Even though its poison is strong, Drapion mostly relies on its physical strength to win battles.

You should use the Poison Sting move as a fast attack and Sludge Bomb as a charged attack. These moves take advantage of its Poison-type, letting you deal much damage and potentially poison your opponent. Drapion is strong in Pokémon GO, making it a valuable addition to your team. If you need a tough Pokémon that hits hard and has strong Poison-type attacks, Drapion could be an excellent fit.

Shadow Muk Is A Gen 1 Dream

If You Can Get It, Keep It

Custom Image by Jorge Aguilar

Shadow Muk is a great Poison-type Pokémon to have in Pokémon GO, especially if you like the Kanto region. It’s a good idea to add one to your team. This Shadow version of Muk can reach a maximum CP of 3,117, which makes it challenging in battles. Its attack stat is 190, which isn’t the highest, but still decent and worth considering.

To find a Shadow Muk, look for cloudy weather, increasing the chances of encountering one. In terms of moves, Shadow Muk performs well with a poison jab, as its fast attack does quick and steady damage. For its charged attack, Gunk Shot is the best option, delivering a strong poison blast. While Muk is mostly known for its poison moves, it can also learn other types, including dark, bug, ghost, and electric moves. This gives you some flexibility during battles if you want to cover different types.

Overqwil Is An Obvious Entry

We All Knew This One Was Tough

Overqwil is one of the best Poison-type Pokémon in Pokémon GO mainly because of its high attack power. With an attack stat of 222, it can deal much damage. Its stamina of 198 helps it stay in battles longer, and it has a decent defense stat of 171. Overqwil can achieve a maximum CP of 3330, making it a strong choice for battles. This Pokémon is really useful when battling opponents due to its impressive damage.

For its moves, a great combo is poison jab and sludge bomb, which works well for a Poison-type. However, you can change things up based on your team’s needs. If you want to include a Ghost- or Dark-type move, you can replace the sludge bomb with a shadow ball or dark pulse. With its strong stats and flexible moves, Overqwil is a fantastic addition to your Pokémon GO team.

Roserade Is A Flower of Poison

Underestimated But Overpowered

Roserade is one of the strongest Poison-type Pokémon in Pokémon GO. This fully evolved Pokémon is impressive because it can deal a lot of damage and apply poison to its opponents, making it quite dangerous in battles. With a maximum Combat Power of 3,359 and an attack stat of 243, Roserade has a strong offensive presence, making it a tough competitor.

Its best Poison-type moves are Poison Jab and Sludge Bomb, but its most effective charged move is actually Grass Knot, which also allows you to use its Grass-type abilities. Having Roserade on your team means you can deal heavy damage and keep poisoning your enemies. I accidentally let a Roserade go, and I regret it so much. Don’t make my mistake because it is so useful.

Shadow Gengar Is Hard To Get

Shadow Gengar Is Still Worth The Effort

Shadow Gengar is a powerful addition to any Pokémon GO team that needs a strong Poison-type and is my favorite on this list. This special version of Gengar, cursed by Team Rocket, has an extra boost in attack power, making it even more formidable in battles. While its maximum combat power is 3254, which isn’t the highest, its strong attack makes it a serious threat.

As a Ghost-/Poison-type, Shadow Gengar has both offensive and defensive strengths. It is weak against Dark-, Ghost-, Ground-, and Psychic-type Pokémon, but it does well against Fairy-, Grass-, Bug-, Normal-, Poison-, and Fighting-type attacks. Its unique combination of types and strong moves like Lick and Sludge Bomb make it versatile. Make sure to get the Lick skill since it can deal 23.43 damage per second and potentially inflict 591.5 damage in one round before being knocked out. To learn Lick, you’ll need an Elite Fast TM.

Mega Venusaur Is Also Great With Poison

Don’t Think It’s Limited To Grass

Mega Venusaur is a strong Poison-type Pokémon in Pokémon GO. When playing the game, it’s best to focus on Mega Venusaur instead of its basic form because it has a higher power, reaching up to 4181 CP. With a defense stat of 246, Mega Venusaur can take a lot of hits in battles. Its attack stat is 241, so it can also deal a good amount of damage.

Sludge Bomb is its charged attack, but the strongest move it can learn is Frenzy Plant, a Grass-type attack. If you want Mega Venusaur to focus more on grass attacks, go for Frenzy Plant. Mega Venusaur is a valuable addition to any team, acting as a strong defender and a powerful attacker.

Mega Victreebel

A Useful Later Addition

Victreebel is one of the latest additions to Pokémon GO, arriving in February 2026, several months after its debut in Pokémon Legends: Z-A. Its debut raid event was unfortunately short, but Pokémon GO always ends up bringing opportunities back around for all of its raids, even if it can sometimes take a while.

Acid and Sludge Bomb are both powerful Poison-type attacks for Mega Victreebel, making its status as one of the strongest Poison-type contenders hard to deny. It might not take the cake as the top Mega Poison type, but that’s more due to how strong some other contenders already are than any deficiency on Victreebel’s part.

Mega Beedrill Is The Simplest To Get

Yet, It Is One of The Top Poison Types

Mega Beedrill is a strong Poison-type Pokémon in Pokémon GO and is considered one of the best. It has a maximum CP of 3824, which helps it perform well in battles. As a Bug- and Poison-type Pokémon, it gets stronger in rainy or cloudy weather. In battles, Mega Beedrill uses a Fast Attack called Poison Jab and a Charged Attack called Sludge Bomb, allowing it to deal damage while also poisoning opponents. It has a high attack stat of 303.

When it comes to strengths and weaknesses, Mega Beedrill is vulnerable to Fire-, Flying-, Psychic-, and Rock-type moves, but it does well against Bug, Fairy, Poison, Fighting, and Grass-type attacks. This makes it a flexible choice for different battles. Mega Beedrill evolves from Beedrill, and evolving it is relatively easy thanks to how often Beedrills show up. Their frequent rate of appearance also makes it easy to nab one in the first place.

Nihilego Is A Powerful Poison-Type

Don’t Let The Appearance Fool You

Nihilego is a great Poison-type Pokémon to have on your team in Pokémon GO, especially if you want to add an Ultra Beast. It can get up to a maximum CP of 4,465, which is high and means it can deal a lot of damage to your opponents. As a dual Rock- and Poison-type, you can customize its moves to fit your strategy.

If you want to focus on its poison abilities, you can use the quick move Pound and the charged move Gunk Shot. This combo lets you poison your enemies and slowly wear down their health. Plus, since it’s an Ultra Beast, it can cause a lot of damage. Nihilego may be second to first, but it’s still a great Pokémon.
