Love wraith
From Tardis Wiki, the free Doctor Who reference
Stacey Facade was a love wraith from the planet Succuba. Love wraiths were shapeshifters who took on the appearance of attractive members of their prey's species, (WC: Stacey Facade) and hypnotised them using pheromones, seemingly making them fall head-over-heels in love with the wraith. This would allow the wraith to feed on their emotions, leaving the victim increasingly drained and depressed. (HOMEVID: Lauren Anderson)
