The Thornbot was created by Dr. Setzer to serve as one of the leaders of his robot army on Caput Tatiium. The Thornbot, due to an error in her circuits, hated technology and forced anyone around her to "put their phones away and put their laptops away". Another error in her circuits caused her voice to come out in a bizarre combination of a southern drawl and an Australian accent. The Thornbot was destroyed during the Battle of Croyuga Castle.
