Horn Drill (move)

Horn Drill is a physical Normal-type OHKO (abbreviation for one-hit knockout) move.

Effect
Horn Drill is a one-hit KO move that faints the target Pokémon instantly if it hits, unless that Pokémon is a higher level than the user, if the target is a Ghost-type under normal conditions, or if it has the ability Sturdy. While Horn Drill has 30% Base Accuracy, it actually increases as the user's level is higher than the opponent's.

Trivia

 * In Generation 1, OHKO Moves worked differently, where the user had to be faster than its target in order to work, compared to Generation 2 onward.
