By the light of the full moon, the Walrus beats on Deadpool with his magical werewolf slaying hammer even though Deadpool gave him the hammer in the first place and isn't, himself, a werewolf. Deadpool gives up and runs away a few times before the impetus that drives him to all of his heroic actions kicks in and gives him the strength to face down one of his most powerful foes (if he don't win the fight, he don't get paid).
