Deldran

Deldran was the seemingly human commander in a war between humans and robots on Bellus IV. The Seventh Doctor arrived and Deldran took him quickly to the human headquarters. There, the remnants of a great experiment to simply turn off the robots had been halted by the death of the chief scientist. The Doctor finished the work, flipped the switch — and promptly discovered that the "human" side were robots, too. As he powered down for good, Deldran explained that the humans had died ages before, leaving the war running by robot proxy. When Deldran used his last bit of power to explain that the robots wouldn't have known what to do with peace, the Doctor echoed the sentiment. He wondered if anyone is really built for peace.
