Darapok
From Tardis Wiki, the free Doctor Who reference
The Darapok were a race of cowardly empire builders. Their empire was known as the Darapok Empire. They preyed upon worlds torn apart by war, where people had lost hope. They invaded Earth in 1944 and tried to brainwash the native humans into killing each other through a transmitter in the Eiffel Tower. The Twelfth Doctor used Time Lord hypnosis to scare the Darapok into fleeing Earth. (COMIC: Trust)
