Psychic-type Pokémon are weak to three types: Bug, Dark, and Ghost. This means Psychic-type issues take neutral or reduced damage from other types, while these three deal super-effective damage to Psychic types. For completeness:
- Offense against Psychic types: Bug, Dark, and Ghost moves are super effective against Psychic-type Pokémon.
- Defense: Psychic-type Pokémon take normal to super-effective damage from other types, with the notable caveat that in many games Ghost-type moves are only partially effective against Psychic types in certain generations, while Dark and Bug consistently counter Psychic.
If you’re building a team or planning a match-up, consider:
- Using Bug-, Dark-, or Ghost-type moves against Psychic opponents to maximize damage.
- Avoiding pure Psychic-type teams where the opponents can leverage those same weaknesses, unless countered with coverage from your own team.
Note: some early-generation mechanics differed (for example, Ghost immunity in Gen I), but in modern games the core weaknesses are reliably Bug, Dark, and Ghost. If you’d like, I can tailor this to a specific generation or game (e.g., main-series games, Pokémon Go, or a particular title) and provide concrete move and typing strategies.
