Mesmerelda (Pac-Man)

Mesmerelda is a powerful Witch and the main antagonist of Ms. Pac-Man: Maze Madness. She possessed the princess of Pac-Land in attempt to rule the country using the Gems of Virtue. Ms. Pac-Man, under the guidance of the kidnapped Professor Pac, is able to capture the Gems, one by one, before Mesmerelda. Unfortunately, Mesmerelda captured the gems from Ms. Pac-Man, and attacked her using her pet Gobblin. Along the way, she also recruited the Ghosts into helping her. Ms. Pac-Man was eventually able to defeat Mesmerelda and restore the Princess back to her normal form.

Mesmerelda seems to be inspired in part by both the animated Pac-Man villain Mezmeron and the Ghost Witch of Netor in Pac-Man 2: The New Adventures.
