Weeping Angel (A Stitch in Time)
From Tardis Wiki, the free Doctor Who reference
A weeping angel was at one point chasing the Eleventh Doctor, River Song, Amy Pond, and Rory Williams at the Winter Quay angel "battery farm". The Twelfth Doctor and Clara Oswald ended up encountering this angel when chasing a Time fly into the portal. The angel ended up vanishing along with the fly when it touched it as the time-potential energy of the fly disagreed with the angel.
