Morphuse

The Morphuse were space travelling, carnivorous humanoids with a reptilian streak (e.g. eyes, tongue). They operated in small packs and feasted on creatures live. When the Eleventh Doctor encountered a gang of ten led by Mistress Zof'lya in Detroit 1970, he arranged for them to be teleported off the Earth by his friend Derek aka Elvis, to be relocated.
