Black Skeletons are in Demon's Souls. Black Skeletons are encountered in the Shrine of Storms. Besides Black Phantom versions that appear during Pure Black World Tendency, only four appear in the game: one guarding a Crescent Falchion near the Archstone of the Shadowmen, one guarding the Adjudicator Shield, one standing in front of the fog gate to the Adjudicator's chamber, and one behind an illusory wall leading to the White Bow.
