Cute Charm

Introduced in Generation III

Whenever a move makes contact with this Pokémon, the move's user has a 30% chance of being infatuated. Overworld: If the first Pokémon in the party has this ability, any wild Pokémon whose species can be either gender has a 2/3 chance of being set to the opposite gender, and a 1/3 chance of having a random gender as usual.

“The Pokémon may infatuate attackers that make direct contact with it.”
