Anticipation
13 Pokémon and forms can have Anticipation: 9 as a regular Ability and 4 as a Hidden Ability.
What does Anticipation do?
When this Pokémon enters battle, if one of its opponents has a move that is super effective against it, Self-Destruct, Explosion, or a one-hit knockout move, all participating trainers are notified. The move itself is not revealed; only that there is such a move. Moves that inflict typeless damage, such as Future Sight, and moves of variable type, such as Hidden Power, count as their listed types. Counter, Metal Burst, Mirror Coat, and one-hit KO moves to which this Pokémon is immune do not trigger this ability.
