Psychic-type Pokemon are weak against Bug, Ghost, and Dark-type Pokemon. Dark-types are especially useful as they are immune to Psychic moves. Psychic moves also don’t do very much damage against Steel Pokemon or other Psychic types. Here are some Pokemon types and specific Pokemon that are good against Psychic-types:

• Dark-type Pokemon: They are immune to Psychic moves and can deal super effective damage against Psychic-types. Some good Dark-type Pokemon to use against Psychic-types are Sableye, Bisharp, and Tyranitar.

• Ghost-type Pokemon: They can deal super effective damage against Psychic-types. Some good Ghost-type Pokemon to use against Psychic-types are Aegislash and Escavalier.

• Bug-type Pokemon: They can deal super effective damage against Psychic-types. Some good Bug-type Pokemon to use against Psychic-types are Scizor and Escavalier.

Remember that some Psychic-type Pokemon may also have a second type, which means they may be weak to other types of damage as well.
