A humanoid breed of Pixie dressed in a tight black corset and fishnet stockings. They wear black gloves and have white feathered wings, and are later redesigned as the Fetish. Their short blonde hair and leather outfit are perfect for hand-to-hand combat and they are especially lethal to vampiristic monsters.
Fay is another word for fairy. Its design was created by Lisa Shock, one of Monster Rancher's fans, for Tecmo's "Design a Monster" contest. It is based on the character Pris from the film Blade Runner.
