Qetesh
From Tardis Wiki, the free Doctor Who reference
The Katesh were a species that fed off excitement in peoples lives. (SJA: Goodbye, Sarah Jane Smith)
Luke Smith defeated the Katesh by using Mr. White to simulate Meteors falling to earth on a large scale, causing 6 billion people to have "thrills" and overloading Ruby White's stomach. (SJA: Goodbye, Sarah Jane Smith) Part 2
