Chelbil
From Tardis Wiki, the free Doctor Who reference
The Chelbil were a rogue race of droids. Because of their limited programming, their sole purpose was to eat any less developed object they came into contact with.
History
In 2017, the Chelbil invaded Earth on Christmas day. They were scared away from the planet by the Eighth Doctor and Goilin B. (ST: Not in My Back Yard)
