Pranavore
From Tardis Wiki, the free Doctor Who reference
Pranavores were a species native to Earth that magnified empathic fields and fed on excess positive human emotions. They were harmless beings and naked to the human eye.
The Tenth Doctor stated he only recently found out about Pranavores and knew little about them. After altering the damaged ocular circuits on a special helmet, he allowed Gabby Gonzalez the opportunity to view the Pranavores, who Gabby thought looked beautiful. (COMIC: Revolutions of Terror)
