Raston Warrior Robot

The Raston Warrior Robot was the most perfect killing machine ever devised. It was a silver android and was one of the deadiest players of the Game of Rassilon in the Death Zone.

The robot hunted by detecting movement and was as quick as lightning. It had built in weapons and could fire disks and arrows from its hands. The robot was incredibly powerful and could even take out a squad of Cybermen in seconds.

When the Death Zone became active again and the Doctor's different incarnations were put in the Zone, the Third Doctor and Sarah Jane Smith encountered the robot but were saved when a Cyberman appeared and the robot attacked it. (DW: The Five Doctors)
