This four-legged combat walker of the All-terrain vehicle line used by the ground forces of the Galactic Republic could be yours. The AT-AT's head will move at HyBall (but not in your home because it does not come with the motor).  This AT-AT is near life-size at roughly 12 ft tall and equally as wide.

Note: this is an event piece intended for one evening. Consequently, it is rough on the edges and will have screw holes in parts of the body.
