Unnerve

Unnerve is an Ability in the Pokémon series that has the primary effect of making opposing Pokémon unable to eat their held Berries during battle. This can significantly disrupt an opponent's strategy, especially if they rely on Berries for healing, status recovery, or other in-battle benefits.

Effects:

Berries Neutralization: When a Pokémon with Unnerve is on the field, opposing Pokémon cannot consume their held Berries. This includes Berries that activate under certain conditions (e.g., when HP falls below a certain threshold) and those used to cure status conditions.
Multi-Battle Influence: In multi-battle formats such as Double Battles and Triple Battles, Unnerve affects all opposing Pokémon on the field, further amplifying its disruptive potential.

Interactions and Exceptions:

Knock Off: While Unnerve stops opposing Pokémon from using their Berries, it does not prevent moves like Knock Off from being used to

Effects

Opposing Pokémon cannot eat held Berries while this Pokémon is in battle. Affected Pokémon can still use bug bite or pluck to eat a target's Berry.
