Fergus Roderick MacLeod (c. 1661 - 1723) was a human, who after death became Crowley; a powerful demon who was the former King of the Crossroads and the King of Hell following Lucifer's possible demise. Although he initially served with Lilith as her right-hand man, he went rogue in Season 5 after her death and Lucifer's release, aiding the Winchester brothers in resealing the latter back into his cage. With the power vacuum in Hell unoccupied, he appointed himself the new King of Hell.
