Weeping Angel (Good as Gold)
From Tardis Wiki, the free Doctor Who reference
A Weeping Angel chased an athlete across the Olympic stadium in an attempt to steal the Olympic Torch and the spirit of the games.
It followed him into the TARDIS and grabbed the torch, but the Eleventh Doctor used his sonic screwdriver to destroy the Angel. However, it reformed moments later, despite missing its right arm. (TV: Good as Gold)
