Pinhead? Quan chi? Although I could be wrong I think you have djinn mixed up with sorcerers. they were originally beings of wind (dust and smoke being an off shoot of this) and fire…mainly fire with a human form based on the people around them notably Arabian people.
Having watched hellraiser im surprised you thought of him when thinking of a djinn. Did you want the djinn to share similar clothes with him and/or quan chi?
