No. Weeping Angels are statues made from stone. Action figures are plastic. If action figures were an enemy in Doctor Who, they would be the Auton. Because the Auton are plastic people who are controlled by an entity called the Nestene Consciousness.
In 2008 with Martha the weeping angels were in it and in the 5th series of doctor who they WILL RETURN i think i know how if they are the same weeping angels that Sally sparrow faced then i think i know. When they defeated them in the house the light bulb was ON and every light bulb has to go out one day and the light bulb might of run out and the weeping angels can't see each other so they can move!!
