Nightmare Undying was one of the planned secondary antagonists in Nightmare Before Disney 2015.
Appearance[]
Nightmare Undying is a heavily withered and distorted version of his classic counterpart. His head seems to have been decapitated from his neck, but hasn't fully broken off as glistening flesh tendrils emerging from his neck have attached themselves to his head, keeping it in place. Where his face would be is instead replaced with dents in the areas where the eyes and mouth should be exposed.
His torso has a massive dent that reaches from his shoulders to the top of his pelvis. His arms appear to suffer somewhat similar withering, except they reveal his body to have a hollow interior. His hands are torn at the wrist, and are replaced with flesh poles that are connected to massive flesh cleavers that glisten similarly to his neck tendrils.
