Unnerve

Unnerve is an ability that prevents opposing Pokémon from using their held Berries while the Pokémon with Unnerve is in battle. This means that if a Pokémon with Unnerve is on the field, any opponent holding a Berry will be unable to benefit from its effects, such as healing or stat boosts. This ability can be particularly useful in competitive battles, as it can disrupt strategies that rely on Berry consumption
