Forewarn (Japanese: よちむ, Hepburn: Prophetic Dream) is an ability that was introduced in Generation IV. It is an exclusive ability to Psychic-type Pokémon.
Effect[]
Forewarn reveals the opponent's move with the highest base power. If there is a tie, one is chosen at random. If the user is facing two opponents, one move in all will be revealed, and it will be the move with the highest base power. Again, if there is a tie, one is chosen at random.
In other games[]
In Mystery Dungeon 2, Forewarn occasionally allows the user to dodge a move, even moves that normally never miss. There is no effect out of battle.
