The Girl With Red Hair / Medusa


 * Voiced by: Rie Saitou (Japanese), Rachel Hirschfeld (English)
 * The most childish and unpredictable of all the monsters featured. She appears as a young red-haired girl. Her transport of choice is a large cruise-liner called "The Hebihanabi," or "Snake Fireworks ship," that can move on land or sea, and is always accompanied by a thick fog. Her sacrifices are turned into stone statues through looking upon her true form, and are either kept in her onboard private collection, or used to decorate the cities under her command (she seems to have a preference for young and beautiful boys.) During one scene in the anime, bunch of snakes are scattered around after she throws her head at a mob of angry parents, implying that she is made out of snakes. One of her oddest features is that she is always accompanied by a servant whose voice is heard, but who never appears onscreen. Whether this servant is another monster or in fact an extension of her power is unknown. She was the monster that scouted out the Monster Union members Midnight Hiyoko and Millionaire Beaver, although she may have found others as well. Like all monsters, her powers are difficult to gauge, and she has an unquestionably evil nature. She is referred to as Medusa by other monsters, which goes along with the fact that she is associated with snakes, can petrify others at will and lastly, when she removed her head it was likely referencing the legend of when Perseus decapitated Medusa in combat, and later used her head (or rather her petrifying eyes) as a weapon. On top of that, The Monster king directly referred to her by the name, Medusa.
