A Pokémon with the Oblivious Ability cannot become infatuated with a Pokémon of the opposite gender. Infatuation can occur by way of use of the move Attract, the Ability Cute Charm, or the held item Destiny Knot.
Oblivious also causes the move Captivate to fail.
Oblivious doesn't have an effect in the Overworld.
