I am NOMAD.
I am PERFECT.
“The Changeling” is a season two episode of the original science fiction television series Star Trek, first broadcast on September 29, 1967 and repeated May 17, 1968. It is episode #32, production #37 and was written by John Meredyth Lucas, and directed by Marc Daniels (who was pictured on-screen as “Dr. Jackson Roykirk”[citation needed]). ...”
The crew of the USS Enterprise deals with an indestructible planet-destroying space probe. The plot contains similarities to the later 1979 Star Trek film.[1]
The USS Enterprise encounters a probe named Nomad. Although originally launched from Earth for peaceful exploration, after colliding with an alien probe it has reprogrammed itself to find and sterilize imperfection. The starship is unable to destroy the probe. Nomad, however, mistakes Enterprise Captain James T. Kirk for its creator, Jackson Roykirk, and allows itself to be brought aboard. After Nomad kills and injures several crew members, Kirk is able to convince the probe it is imperfect, as it mistook Kirk for Roykirk. Consistent with its altered programming the probe commences “sterilizing” (destroying) itself. The Enterprise crew safely transports Nomad into space before the latter explodes.”
