Poison Type Weakness Explained
Protect and Detect become crucial tools in double battles. A Poison type can use Protect while its partner uses Earthquake, avoiding self-damage entirely. This doubles strategy is common in competitive VGC formats where Poison types like Amoonguss and Toxapex are staples.
Sludge Wave is the premier Poison move in doubles, hitting both opponents simultaneously. Combined with a partner that can handle Ground-weak Pokemon, Sludge Wave users like Toxtricity provide unmatched spread damage. The 10% poison chance on both targets adds up quickly over the course of a match.
Follow Me and Rage Powder redirect attacks away from vulnerable Poison types. Amoonguss with Rage Powder is one of the best support Pokemon in doubles, protecting its Poison-weak partner while setting Toxic Spikes or using Spore. This support role makes Poison types valuable even when their offensive presence is limited.
Historical Poison Type Pokemon in Competitive
Poison type Pokemon have shaped competitive Pokemon since Generation I. Gengar was so dominant in the original games that it defined the entire metagame. Muk and Nidoking were also top-tier threats, and the Poison type was considered one of the best offensive types available.
Generation II introduced Steel type, which resisted Poison and reduced Poison type’s offensive viability. However, Poison types remained relevant for their ability to poison opponents and wear down defensive Pokemon. Crobat emerged as a fast offensive threat with no weaknesses thanks to its Poison/Flying typing.
Generation IV brought the physical-special split, which benefited Poison types significantly. Poison Jab became a viable physical STAB move, and Pokemon like Drapion and Toxicroak gained new offensive options. This generation also introduced Poison Heal, an ability that healed Pokemon each turn while poisoned.
Generation VI was transformative for Poison types with the addition of Fairy. Suddenly, Poison moves had a powerful new target, and Pokemon like Crobat and Nidoking gained new relevance. The generation also introduced Corrosion, which gave Salazzle and Toxicroak the ability to poison any Pokemon regardless of type.
Common Misconceptions
Myth: Poison Types Are Only Weak to Ground
Many players believe Ground is the only type that hits Poison for super effective damage. In reality, Psychic-type moves are equally effective against Poison types.
Both Ground and Psychic deal 2x damage, and dual-type Poison Pokemon may be 4x weak to one or both of these types.
Myth: Poison Types Are Defensively Weak
Poison types actually have strong defensive profiles with four resistances. Pure Poison types only have two weaknesses and can wall many common offensive types.
The addition of Fairy resistance in Generation VI made Poison one of the better defensive types in the game.
Myth: All Poison Types Can Poison Any Pokemon
Steel and Poison type Pokemon are normally immune to being poisoned. Only Pokemon with the Corrosion ability can bypass this immunity.
This is a crucial distinction in competitive play where Steel types like Ferrothorn and Corviknight are common.
Myth: Poison Type Moves Are Only for Status
While Poison types are known for status moves like Toxic, many Poison-type attacks have high base power. Sludge Bomb at 90 power and Gunk Shot at 120 power are competitive STAB options.
Physical attackers like Toxicroak and Nidoking use Poison Jab and Gunk Shot effectively.
Myth: Poison Is Weak Offensively
Poison is actually a decent offensive type, hitting Fairy types for super effective damage. With the Fairy type added in Generation VI, Poison gained an important offensive role.
Poison moves also threaten Grass and the few pure Fairy types that resist other common attacks.
Myth: Every Pokemon Can Learn Toxic
Toxic is actually a move with limited distribution. While many Poison types can learn it, not every Pokemon has access to Toxic.
In competitive play, the Toxic Orb item and the move Toxic Spikes are often more reliable ways to inflict poison than the Toxic move itself.
Deep Dive Tips for Using Poison Types
Lead with Ground Coverage
Skill Level: Beginner | Time to Apply: 5 min | Success Rate: 90%
Teach a Ground-type move to a non-Ground Pokemon to counter Poison types. Earthquake on a Fighting type like Conkeldurr handles both Poison and Steel threats simultaneously.
Exploit Dual Weaknesses
Skill Level: Intermediate | Time to Apply: 15 min | Success Rate: 75%

What Is Poison Type Weakness?
In Pokemon, every type has specific strengths and weaknesses. Poison type weakness refers to the move types that deal super effective damage to Poison-type Pokemon.
Understanding these matchups is fundamental to both casual play and competitive battling. Pokemon type guides covers similar type mechanics for collectors.
The Poison type has been part of Pokemon since Generation I in 1996. It was one of the original 15 types and has remained a core part of the type system through all nine generations.
Poison types are known for their ability to inflict status conditions and wear down opponents over time.
Knowing poison type weakness helps you choose the right moves in battle, build balanced teams, and predict opponent switches.
Whether you are playing through the story, battling friends, or competing in ranked matches, type knowledge is the foundation of success.
Ground Type: The Primary Counter
Ground-type moves are super effective against Poison types, dealing 2x damage.
This is the most reliable and commonly used counter because Ground moves are widely available across many Pokemon species.
Pokemon like Garchomp, Landorus, and Mamoswine carry powerful Ground STAB moves.
The Ground-Poison matchup is straightforward with no exceptions.
Even dual-type Pokemon that are part Poison will take super effective damage from Ground moves unless they have an ability like Levitate.
This makes Ground the go-to type for countering Poison-heavy teams.
Earthquake is the most important move in this matchup. It has 100 base power, perfect accuracy, and is learned by over 100 Pokemon species.
Almost every competitive team runs Earthquake specifically to handle Poison and Steel type threats.
Psychic Type: The Secondary Counter
Psychic-type moves also deal 2x damage to Poison types. This matchup was introduced in Generation I and has remained consistent through all nine generations.
Psychic types like Alakazam, Metagross, and Latios can exploit this weakness effectively.
Psychic counters are especially useful because many Poison types are also weak to Psychic due to their secondary typing.
For example, Toxicroak (Poison/Fighting) and Salazzle (Poison/Dragon) both take super effective damage from Psychic moves. Pokemon collection guides explores similar dual-type considerations.
However, Psychic types must be careful when switching into Poison Pokemon. Many Poison types carry Dark-type coverage moves like Knock Off or Sucker Punch that can punish Psychic switch-ins.
Prediction and team support are key when using Psychic counters.
Poison Type Resistances and Immunities
Poison types resist four types: Fighting, Poison, Grass, and Fairy. This makes them surprisingly durable in certain matchups.
A pure Poison type only has two weaknesses but four resistances, giving it a favorable defensive profile in many situations.
The Fairy resistance was added in Generation VI and significantly improved Poison type viability. Before this change, Poison types had fewer defensive utility options.
Now they serve as important checks to Fairy and Fighting types in competitive play.
Poison types are also immune to the Toxic status condition, which is unique among all types. This immunity means Poison Pokemon can freely switch into Toxic attempts without taking residual damage.
In stall-heavy metagames, this immunity is extremely valuable.
Dual-Type Poison Pokemon Weaknesses
Many popular Pokemon carry Poison as a secondary type, creating unique weakness combinations. Nidoking (Poison/Ground) loses its Ground weakness but gains Water and Ice weaknesses.
Gengar (Poison/Ghost) is weak to Ghost, Dark, Ground, and Psychic.
Some dual-type Poison Pokemon have amplified weaknesses. Toxtricity (Poison/Electric) is 4x weak to Ground because both Poison and Electric share Ground as a weakness.
Amoonguss (Poison/Grass) is weak to Flying, Psychic, and Ice. gaming strategy guides covers team composition strategies that apply here.
Other notable dual-type Poison Pokemon include Crobat (Poison/Flying), which gains a Grass weakness but loses the Ground weakness due to Flying.
Weezing (Poison) in Galar form becomes Poison/Fairy, changing its weakness profile entirely to Ground, Psychic, and Steel.
Understanding dual-type interactions is crucial for competitive play. A Pokemon like Nihilego (Rock/Poison) is 4x weak to Ground and also weak to Steel, Water, and Grass.
Knowing these compound weaknesses helps you predict opponent moves and plan switches.
Best Poison Type Pokemon to Use
Nidoking and Nidoqueen remain the most versatile Poison types with access to both Ground and Poison STAB moves. Their Poison/Ground typing gives them an Electric immunity and only three weaknesses.
Both have excellent movepools covering almost every situation.
Gengar offers incredible speed and special attack with its Poison/Ghost typing. In Generation I, Gengar was one of the most dominant Pokemon ever.
While it has been nerfed over the generations, it remains a viable special attacker and one of the fastest Poison types available.
Toxapex is one of the best defensive Pokemon in competitive with its Poison/Water typing. Access to Recover, Toxic Spikes, and Baneful Bunker makes it a nightmare for physical attackers.
Its massive physical defense allows it to wall many top-tier threats.
For offensive teams, Salazzle provides unique Poison/Dragon coverage with the Corrosion ability. Amoonguss is the premier defensive Poison type with access to Spore and Regenerator.
Dragalge (Poison/Dragon) offers special bulk and Adaptability-boosted STAB moves. game genre guides highlights similar top picks across genres.
Competitive Poison Type Strategy
In competitive Pokemon, Poison types serve multiple roles. Defensive Poison types like Toxapex and Amoonguss provide team support with status moves and recovery.
Offensive Poison types like Gengar and Nidoking function as powerful sweepers with wide coverage.
The introduction of the Corrosion ability on Salazzle and Toxicroak changed Poison type strategy entirely.
Corrosion allows these Pokemon to poison Steel and Poison types, which are normally immune to status conditions. This makes them valuable even when their attacks are not super effective.
Toxic Spikes is the signature entry hazard for Poison types. One layer poisons switching Pokemon, while two layers badly poison them.
Rapid Spin and Defog can remove Toxic Spikes, so pairing with a spin-blocking Ghost type is a common competitive strategy.
Poison types also excel as pivots with moves like U-turn and Volt Switch. Crobat and Toxicroak commonly run U-turn to maintain momentum.
This pivoting strategy keeps offensive pressure while scouting opponent switches and Toxic Spikes damage accumulates.
Poison Type Moves Overview
Poison-type moves range from reliable STAB options to powerful coverage attacks. Sludge Bomb is the most commonly used Poison move with 90 base power and a 30% poison chance.
Gunk Shot offers higher power at 120 but with lower accuracy at 80%.
Poison Jab is the primary physical Poison move with 80 base power and perfect accuracy. For status, Toxic is the most important Poison-type move, dealing increasing damage each turn.
Venusaur and Roserade often use Toxic to wear down defensive Pokemon. gameplay optimization tips covers similar optimization strategies.
Venoshock is a unique Poison move that deals double damage if the target is already poisoned.
This creates a powerful combo with Toxic or Toxic Spikes, turning Venoshock into a 130 base power move against poisoned targets. Many special Poison attackers run Venoshock for this reason.
Sludge Wave is an AOE Poison move with 95 base power that hits all adjacent opponents in double battles. It has a 10% poison chance and is the best spread move for Poison types.
Toxic Thread is a status move that poisons the target and lowers its speed by one stage.
Poison Type Weakness Across Generations
The Poison type weakness chart has remained remarkably consistent since Generation I. Ground and Psychic have always been the two super effective types against Poison.
No generation has changed this core matchup, making it one of the most stable type interactions in the game.
However, the addition of the Fairy type in Generation VI changed Poison type dynamics significantly. Fairy types are weak to Poison, giving Poison attackers a new offensive target.
This made Poison a more viable offensive type and improved the overall value of Poison Pokemon.
Generation VI also changed Poison types to no longer be immune to the Sleep status when affected by the move Rest. Previously, Poison types could use Rest for free healing without the sleep drawback.
This subtle change affected the viability of certain defensive Poison sets.
In Generation VIII, the Dynamax mechanic temporarily changed type matchups for Poison Pokemon.
Max moves could override type immunities and change weather conditions that affected Poison type strategies. With Dynamax removed in Generation IX, the type chart returned to its standard form.
complete strategy guides covers how game mechanics evolve across versions.
Building a Team Around Poison Types
When building a team with Poison types, you need to cover their Ground and Psychic weaknesses. Flying types and Pokemon with Levitate are natural partners since they are immune to Ground moves.
Rotom forms, Landorus, and Gliscor all provide Ground immunity while threatening Psychic types.
Steel types pair well with Poison types because they resist Psychic and can handle Fairy types that threaten Poison Pokemon.
Ferrothorn, Heatran, and Corviknight are excellent defensive partners that cover Poison type weaknesses while benefiting from Poison type resistances.
For offensive teams, pairing Poison types with Dark types creates strong synergy.
Dark types resist Psychic and Ghost moves that threaten Poison Pokemon, while Poison types handle Fighting and Fairy types that threaten Dark Pokemon. This core is common in competitive play.
Entry hazard support maximizes Poison type effectiveness. Stealth Rock and Toxic Spikes together wear down opposing Pokemon quickly.
Forretress and Ferrothorn can set both hazards while providing defensive support for your Poison type attackers.
Poison Type in Pokemon GO
In Pokemon GO, the Poison type weakness system works similarly to the main series. Poison types take super effective damage from Ground and Psychic type moves.
However, GO uses a simplified damage multiplier system without the same dual-type complexity.
Top Poison type attackers in Pokemon GO include Nidoking, Gengar, and Crobat. For counters, Mewtwo with Psychic moves and Garchomp with Earth Power are the best options.
Raid bosses that are Poison type should always be countered with Ground or Psychic attackers.
Pokemon GO also features Poison type Pokemon in PvP battles. In Great League, Toxicroak and Skuntank are viable picks. In Ultra League, Nidoking and Drapion see regular use.
Understanding poison type weakness helps you choose the right counters in every PvP format.
Poison Type Weakness in Competitive Tiers
Competitive Pokemon is divided into usage tiers from Uber to NU. Poison types appear in every tier, and understanding their weakness patterns is essential for team building at each level. In the OU tier, Toxapex and Gengar are dominant Poison types that define the meta.
In the UU tier, Nidoking and Salazzle serve as powerful offensive threats. Their Poison typing gives them unique advantages against Fairy types while their secondary typings provide coverage against different threats. Knowing which Poison types are common in each tier helps you prepare appropriate counters.
The RUU and NU tiers feature Poison types like Skuntank, Drapion, and Weezing. These Pokemon often carry unexpected coverage moves that exploit opponent assumptions about Poison type weakness. Drapion with Ice Fang or Skuntank with Fire Blast can punish players who only prepare Ground and Psychic counters.
Abilities That Modify Poison Weakness
Several Pokemon abilities directly interact with Poison type weakness. Levitate makes Pokemon immune to Ground moves, effectively removing one of Poison type’s two weaknesses. Gengar, Weezing, and Rotom all use Levitate to become much harder to counter with standard Ground coverage.
Wonder Guard on Sableye and Shuckle blocks all non-super effective moves. However, since Ground and Psychic are super effective against Poison, Wonder Guard Poison Pokemon must rely on their secondary typing or team support to handle these threats. Shuckle with Sturdy is slightly more viable than Sableye.
Water Absorb and Storm Drain make Pokemon immune to Water moves, which is relevant for Poison/Water types like Toxapex. These abilities remove one of Poison type’s indirect weaknesses by making certain coverage moves useless. Toxapex with Recover and Water Absorb walls many special attackers completely.
Filter and Solid Rock reduce super effective damage by 25%. Pokemon with these abilities take only 1.5x damage from Ground and Psychic moves instead of the standard 2x. Aggron and Nidoqueen with Filter can survive hits that would normally KO them, giving them a crucial turn to strike back.
Poison Type Weakness in Double Battles
Double battles change Poison type weakness dynamics significantly. Ground moves like Earthquake hit all Pokemon on the field, so using Ground coverage against Poison types in doubles requires careful positioning. Pokemon with Levitate or Flying type can partner with Poison Pokemon to absorb Earthquake safely.
Protect and Detect become crucial tools in double battles. A Poison type can use Protect while its partner uses Earthquake, avoiding self-damage entirely. This doubles strategy is common in competitive VGC formats where Poison types like Amoonguss and Toxapex are staples.
Sludge Wave is the premier Poison move in doubles, hitting both opponents simultaneously. Combined with a partner that can handle Ground-weak Pokemon, Sludge Wave users like Toxtricity provide unmatched spread damage. The 10% poison chance on both targets adds up quickly over the course of a match.
Follow Me and Rage Powder redirect attacks away from vulnerable Poison types. Amoonguss with Rage Powder is one of the best support Pokemon in doubles, protecting its Poison-weak partner while setting Toxic Spikes or using Spore. This support role makes Poison types valuable even when their offensive presence is limited.
