Once upon a time, the evil Lich cursed a gungeoneer to a life of undeath. Over the years, the gungeoneer has withered away, becoming naught but bones. His original identity long forgotten, the Skeleton wanders the halls of the Gungeon, hoping to reclaim his lost memories.

The Skeleton starts with a sling, and an innate sense of direction that comes from his manys years of wandering. The Skeleton's curse also imbues his bullets with extra strength.
