Carrionite

The Carrionites were a species of humanoids, the only notable difference in appearance from near-Humans being wrinkled faces and teeth being entirely sharp canines. They could also fly, dematerialise and rematerialise at will, their abilities described as witchcraft.

A group of three attempted to invade Earth in 1599. William Shakespeare had to give the performance of his life with the help of the Doctor and Martha Jones to save the world from the trio of flying witches, as the Earth would have been destroyed if he didn't.

The Carrionites were probably his inspiration for the Weird Sisters of his play, Macbeth. (DW: The Shakespeare Code)
