 The character of the Master was designed to be in vamp face permanently to highlight his age and make him appear more animalistic; make-up artist John Vulich based the Master's appearance on a bat, reasoning that the character has devolved to a more primal, demonic state over the years.It was decided that vampires and their clothes would turn to dust after they died.This was done for practical storytelling reasons, so the characters would not have to spend time cleaning up bodies.
