Forewarn

Effect

Reveals the opponents' strongest move upon entering battle.

When this Pokémon enters battle, it reveals the move with the highest base power known by any opposing Pokémon to all participating trainers.

In the event of a tie, one is chosen at random.

Moves without a listed base power are assigned one as follows:

Power	Moves
160	One-hit KO moves: Fissure, Guillotine, Horn Drill, and Sheer Cold
120	Counter moves: Counter, Metal Burst, and Mirror Coat
80	Variable power or set damage: Crush Grip, Dragon Rage, Electro Ball, Endeavor, Final Gambit, Flail, Frustration, Grass Knot, Gyro Ball, Heat Crash, Heavy Slam, Hidden Power, Low Kick, Natural Gift, Night Shade, Psywave, Return, Reversal, Seismic Toss, Sonic Boom, Trump Card, and Wring Out
0	Any such move not listed

In battle

On switch-in, this Pokemon is alerted to the move with the highest power, at random, known by an opposing Pokemon. This effect considers OHKO moves to have 150 power, Counter, Mirror Coat, and Metal Burst to have 120 power, every other attacking move with an unspecified power to have 80 power, and non-damaging moves to have 1 power.

Main-series effects may vary by game.
