Forewarn shows the opponent's move with the highest base power. If two or more moves are of the same base Power, one will be chosen at random.
In a double battle, Forewarn will only show the highest base power move of out of the two opponents. If both opponents have a move with the same base power, one will be chosen at random. Moves without a base power that can cause damage are assigned one.
In Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness, a Pokémon with Forewarn occasionally evades moves, even moves that never miss.
