Centaurs were a species of supernatural being; half-human, half-horse. One of these creatures was a witch living in another dimension, who helped Willow Rosenberg restore the Scythe. Dawn Summers was temporarily transformed into a centaur by Kenny. There were at least two humans who were transformed into centaurs due to Whistler's plague ball.
