Skarmory

A notorious run killer, Skarmory was a fearsome opponent wielded by the Flying-type Gym Leader Skyla from Black and White 2. Skarmory is known for ending Ludlocke runs 16 and 17. In its most infamous battle with Ludwig, Skarmory ended run 16 by defeating Snorlax, Shroomish, Dragonite, Machoke, and Excadrill. In run 17, Skarmory ended the run by killing Ludwig's Gigalith and Buneary. There may be another run that Skarmory ended that has yet to be determined.
