The "planet killer" was an informal name given by Spock in 2267 to an automated, self-propelled doomsday machine capable of destroying entire planets. This robot was encountered by the Federation starships USS Constellation and USS Enterprise. Its origins were unknown, but based on its apparent trajectory, it was believed to have come from a galaxy other than the Milky Way.

On or about stardate 4202.1 the Constellation, under the command of Commodore Matt Decker, encountered massive destruction in system L-370 - all seven planets had been utterly destroyed. Proceeding to system L-374 (stardate 4202.3), the ship found three intact planets, and a fourth in the process of breaking up. Orbiting the fourth planet was the planet killer, firing a pure antiproton beam at the planet and consuming the planet's rubble as fuel.

As the Constellation approached, it was attacked by the planet killer. The ship's deflector shields were quickly overwhelmed by the onslaught. The machine proved completely invulnerable to counterattack because its hull was composed of pure neutronium. The Constellation sustained heavy damage. The main bridge was destroyed, the phaser banks were exhausted, the warp drive was destroyed and the impulse drive was severely damaged. In addition, the machine projected a powerful dampening field which cut off all communications with Starfleet Command. The field also deactivated the Constellation's antimatter fuel and left the ship nearly powerless.

Unable to continue the attack or escape, Decker ordered the crew to evacuate to the third planet in the system. Decker himself remained aboard as the last man. However, having finished consuming the fourth planet, the machine then turned towards the third planet. Decker tried to beam his crew back up, but the machine attacked again, damaging the transporter. He could only watch helplessly as the machine consumed the planet below and killed his entire crew of 400 men and women.

A short time later, the Enterprise, under the command of Captain James T. Kirk, received a faint and garbled distress signal. Unable to make out any words aside from Constellation, she entered system L-374 and found her sister ship drifting and abandoned, with Commodore Decker the sole survivor aboard. Assessing the situation using the Constellation's sensor records taken by science officer Masada, Spock projected the weapon's origin. He also determined, based on its present course, that it would enter the most densely populated regions of the Alpha Quadrant, including the nearby Rigel system. Decker became determined to stop the threat posed to the Federation by the planet killer.
