Automated corpse

The automated corpses were journalists who began to realise the Fourth Great and Bountiful Human Empire was controlled by the Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe, who were then killed and controlled by brain chips. The chips were controlled by the Editor, who was controlled by the Jagrafess, which was controlled by the Daleks.

The dead bodies were frozen and used to monitor everything happening on Satellite Five. When the Jagrafess was about to explode, the chips were deactivated, but the bodies were still almost alive. The Editor tried to make a run for it, but Eva Saint Julienne (one of the corpses) grabbed his legs so he died with them. All of the corpses were killed when the Jagrafess exploded.
