Lepus Warrior

The Lepus Warriors were a species of advanced alien rabbits from another dimension that used warp technology to travel between worlds in order to invade and conquer.

An attempt to invade Earth in 1923 involved disguising a warp gate as a top hat used by the stage magician Miraclo. From the hat came not one rabbit but an army of alien rabbits who began shooting their way through a packed theatre in New York City.

Their plan was foiled by the Eleventh Doctor and Clara who used the Warriors' weakness to hypnosis and the Doctor focused their attention on his fob watch before convincing them to return back through the warp gate before it was crushed. (COMIC: The Hat Trick)
