- If you have a Poison Pokemon, they are extremely effective against Grass and Fairy-type Pokemon as of generation six.
- Similarly, they perform worse against Ground and Psychic-type Pokemon as of generation six.
- However, they have resisted fighting, poison, bugs, grass, and fairy-type Pokemon since generation six.
Since we have covered some popular Pokemon elements, it is time to discuss Poison. It’s another of my favorites, and it comes with its own set of interesting advantages and disadvantages. However, if you’re a new player in Pokemon GO, this element type might not make sense immediately. To help you with that and then some, we have compiled a dedicated guide for Poison Pokemon. So, with that, let’s begin!
Poison Pokemon Strengths

Poison-type Pokemon are strong against Fairy and Grass-type Pokemon.
When the first generation of Pokemon came out, a Poison Pokemon was extremely effective against Bug and Grass-type Pokemon. This means your Gengar with Sludge Bomb will fare well against a Bulbasaur or Scyther in most cases.
Then, when generations two, three, four, and five rolled out, these monsters were only good against a Grass Pokemon. However, bug types were somehow ineffective for the most part. It might be a case of Game Freak experimenting with the monster type in-game.
Finally, from generation six onwards, Poison monsters have only been powerful enough to fight against a Grass and Fairy-type. The grass type has always stayed constant throughout the years. However, the second element type is what has changed within two generations. So take the final strengths as the ultimate Poison Pokemon strengths.
Poison Pokemon Weaknesses

Similar to its strengths, Poison monsters have also had changes to their weaknesses across different generations. As of now, Poison Pokemon are only weak against Ground and Psychic-type moves.
A Koffin would perform badly against Ground, Bug, and Psychic-type monsters when the first generation rolled out. However, their weaknesses changed to Ground and Psychic Types during generations two, three, four, and five. This means that a Koffin will have trouble fighting against an Alakazam.
The weakness has changed from generation six to Ground and Psychic-type Pokemon. So, if it is one with both of these properties, your Poison-type will have difficulty fighting against them.
Poison Pokemon Resistance
Poison-type resists Fighting, Bug, Grass, Fairy, and Poison-type itself. However, this wasn’t always the same.
In the first generation, a Poison monster resisted Fighting fellow Poison-types and Grass-Types. When the later generations rolled in, the resistance changed from the above three to Ground-type, Rock-Type, and Ghost-type. However, poison types remained untouched. Finally, from generation six onwards, the list of elements changed again. The first-generation resistant made a comeback in the Pokemon Type Chart, alongside two new ones.
Best Counters for Poison-Type Pokemon
Poison-type Pokemon have a few solid resistances, but they also struggle against some powerful typings. Since they are only weak to Ground and Psychic-type attacks, choosing the right counters becomes very important. Here are some of the best Pokemon to use against Poison-types:
- Mega Garchomp (Dragon / Ground)
- Primal Groudon (Ground / Fire)
- Mega Alakazam (Psychic)
- Mewtwo (Psychic)
- Excadrill (Ground / Steel)
Best Poison-Type Pokemon

- Mega Gengar (Poison / Ghost)
