The Puppet Master has the appearance of a skeleton. Her skull looks similar to Papyrus's, but it has Sans's mouth and eyes. Her eye sockets are normally pitch black, but when she's fighting, her pupils become visible and glow green. She usually wears pitch black cloak that covers her outfit and eyes. The PM's outfit is full dark green armor with dark green leather boots. She also wears a golden locket. The PM is about as tall as Papyrus.
