Gorilla Tacticsin Pokémon Polished Crystal

Gorilla Tactics is an ability that boosts the user's Attack by one stage but only allows the user to use the first move it selects. In Polished Crystal, you can only see this ability on Primeape and Annihilape whom have it as their primary ability. This ability works similarly to the Choice items such as Choice Band. If the user tries to use a different move than the first one selected, it will fail. However, if the user is forced to switch out, it can select a new move when it returns to battle.
