Philip K. Defender

Science-fiction authors Philip K. Dick and Ursula LeGuin were the inspirations for two members of the psychic Chorus that acquired mental control of Over-Mind (Defenders #117). Coincidentally, Philip K. Dick also wrote a short story called "The Defenders." Following a nuclear war with the Soviet Union, humans in that story live underground to stay safe from radiation. Robots, meanwhile, remain on the surface for defensive purposes. The reality of the situation, however, is more insidious than the characters initially believe.

"The Defenders" first appeared in the pages of Galaxy Science Fiction (January 1953).
