Scary Face, Pokémon Wiki

Scary Face is a Normal-type move introduced in Generation II that stats the skill move that decreases the foe's speed. Some Pokémon in the anime are shown using this, but it only carries the effect to scaring the opponent and thus delaying their attack. Scary Face rapidly decreases the opponent's speed when it becomes frightened by the enemy's intimidating appearance. In Generation II, III and IV Scary Face had 90% Accuracy.
