Weeping Angel

The Weeping Angels are a race of fictional predatory alien creatures from the long-running British science fiction television series Doctor Who. The Weeping Angels look like stone statues to an observer since they only can move when unobserved. Weeping Angels feast by touching a victim; the victim is sent back in time, and the Angel feeds on the resulting time energy from the time travel caused. The Weeping Angels were introduced in the 2007 episode "Blink" and became recurring characters across a variety of Doctor Who media. These later episodes expand the Angels' list of abilities, which include the ability for an image of an Angel to become another Weeping Angel, the ability to turn other statues into Weeping Angels, and the ability to kill others by touching them twice.
