What is crobat weak against?

Crobat is weak against the following types:

1. Rock - Rock-type moves can deal super-effective damage to Crobat as it is a Flying/Poison-type Pokémon.

2. Electric - Electric-type moves can hit Crobat's weakness against its Flying-type, dealing 4x super-effective damage.

3. Psychic - Psychic-type moves can also deal super-effective damage to Crobat due to its Poison typing.

4. Ice - Ice-type moves can also hit Crobat's Flying-type weakness and deal super-effective damage.

It is also important to note that Crobat's ability, Inner Focus, makes it immune to flinching, so moves like Fake Out that typically cause flinching will not be effective against it.
