Suction Cups

Introduced in Generation III

This Pokémon cannot be forced out of battle by moves such as Whirlwind. Dragon Tail and Circle Throw still inflict damage against this Pokémon. Overworld: If the lead Pokémon has this ability, the success rate while fishing is increased.

“The Pokémon uses suction cups to stay in one spot. This protects it from moves and items that would force it to switch out.”
