First UK Story Arc
The Universe Star Ship  left Earth's atmosphere to embark on a five year deep space exploration. Massive in proportion and manned by thousands, the Enterprises mission is to make peaceful contact with any form of life in the universe.

The U.S.S. Enterprise… captive on a planet of robots!

Summary

While on a star mapping mission, the ship encounters interference, which they think was cause by a supernova. When they experience turbulence, Spock realizes that the viewscreen is showing them footage in a repeating loop. A repair wagon is sent to fix the exterior cameras, and it is discovered that they are orbiting a planet. The crew confirms the planet's existence by opening viewing ports, although it does not register on any instruments.

Since the computers are giving false readings, Kirk orders them all disconnected. A crewman is given a strong electrical shock as he tries following orders, and a message arrives through the computer. It warns that no one should disconnect any more computers and that the ship will be brought in for a landing. As the ship lands, robots greet the crew and warn them not to resist. Once the entire crew is lined up, the robots stun them and load them into mobile transports.

Kirk and a few officers escape their transport and enter a large building. They see a large statue, made in the image of a humanoid scientist. A crewman finds a helmet and puts it on, receiving some sort of shock. In response, the pedestal of the statue slides away, and a mechanical arm grabs the crew.

The system outfits Kirk and his men with helmets to communicate with them. It claims that Humans built the robots and abandoned them on the planet a million years ago. Spock muses that Humans could have come from somewhere prior to Earth. The robots' power source is dying out, and they are dismantling the Enterprise for a new power source. Since the Master Computer was built by Humans, it is programmed not to harm them, as opposed to the robots, who were constructed by other robots.

Robots enter and apprehend Kirk and his men, forcing them to assist in accessing power rods from the ship's engine. Kirk sabotages a power rod, timing it to detonate. As he exits the ship, Sulu, Bailey, and some crewmen, armed with clubs, make a savage attack on a group of robots. The robots overpower the men, and direct Kirk to install the power rod himself.

Kirk, Spock, and some robots travel to the power unit building in the city, and detonate the rod after installation. In turn, all the robots collapse through loss of power and the city is left in flames.

In canon, a  vessel does not have landing capability. Nevertheless, some scenes of the Enterprise on the planet's surface resemble the  's landings.
In the landing scene, a captain's yacht descends from the underside of the saucer section.
One crewman wears sunglasses.  colors come in red, orange, yellow, green, and blue variants.
In a , the transport bearing the captive command crew spontaneously explodes, freeing Kirk to plan escape from the robots.
The shrine to an ancient scientist has a "Jesus Fish" on its pedestal.
The hazard suits Kirk and Spock don for the engine room prefigure those seen in , although this version includes a helmet that completely obscures the wearer's face.
The engine's power rod is stored in a cobalt container for transport.
Signage on the robots' buildings resembles  punctuation. For example, the power unit building says "<-//!=".
The robots resemble the  series of robots from .
