Poison types in Pokémon are weak to Ground and Psychic moves. This means they take double damage from those attacks, making them vulnerable in battles. Ground and Psychic Pokémon or moves are your go-to counters.

Core Weaknesses

Poison-type Pokémon suffer 2x damage from:

  • Ground : Moves like Earthquake hit hard and bypass many defenses.
  • Psychic : Attacks such as Psychic or Psyshock exploit Poison's mental vulnerabilities.

They resist Fighting, Poison, Bug, Grass, and Fairy (0.5x damage), and Steel types are immune to Poison moves.

Type Chart Overview

Type| Damage to Poison| Notes 19
---|---|---
Ground| 2x| Common and powerful; watch for Levitate ability.
Psychic| 2x| Strong special attackers dominate.
Fighting| 0.5x| Reliable resistance.
Poison| 0.5x| Self-resistance; immune to status poison.
Grass| 0.5x| Poison hits Grass super effectively.

Forum Insights

Reddit discussions highlight why Poison feels "weak" offensively—its moves only super-hit Grass and Fairy, and many Poison Pokémon are slow.

"Poison is weak to two really common & powerful types: ground & psychic... That said, they have some decent resistances."

Competitive players pair them with Steel or Flying to cover Ground weakness, like Drapion or Weezing.

Battle Tips

  • Lead with Ground : Garchomp or Excadrill sweeps Poison teams.
  • Psychic Sweepers : Alakazam or Mewtwo pressure from afar.
  • Avoid common pitfalls: Air Balloon items temporarily negate Ground weakness.

This holds true as of latest Pokémon data into 2026—no major changes in Scarlet/Violet era.

TL;DR : Poison is weak to Ground and Psychic —use those to counter effectively.
