"The Raston warrior robot. The most perfect killing machine ever devised."

- The Doctor.

Raston Warrior Robot are the most perfect killing machine ever devised. They are silver androids and one of the deadliest players of the Game of Rassilon in the Death Zone.

Overview
The robot hunted by detecting movement and was as quick as lightning, It moves by jumping in the air and dissapearing then reappearing at its destination. It had built in weapons and can fire disks and arrows from its hands. It enjoyed toying with its prey. The robot was incredibly powerful and could kill a squad of Cybermen in under a minute.

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 by a cave entrance. They were forced to remain still, just as they were tiring of remaining still a patrol of Cyberman appeared and the robot attacked them. It fired a barrage of arrows into their chestplates and killed them all. Inside the cave Sarah and the Doctor found the robots spare arrows and for some unknown purpose there was also rope there.

They are capable of feeding on atomic radiation in the atmosphere which means that they never run down. The loss of their heads does not diminish their efficiency as they can just simply reattach them. They are also programmed to consider anyone except their Makers as their Enemy. They attack by locking onto the electrical activity of the target's brain with two people possessing the same pattern causing the robot to jam. The javelins they extruded were generated by the Raston warrior robot whose entire weapon system was built-in (EDA: The Eight Doctors)


 * Some fan speculation states that the Raston warrior robots were created by Rassilon himself in the war against the Great Vampires though no novel or episode confirms this view.



History
