Memory Beta, non-canon Star Trek Wiki

"The Klingon Ultimatum" was a 12-page Star Trek: The Original Series comic strip published in 1970. It was the 11th story arc in the UK comic strips series, released in six parts within issues of TV21 & Joe 90. This was the last of 11 stories illustrated by Harry Lindfield. In this story, the Klingon Empire aimed a metaweapon at Earth.


Teaser, 24 January 1970
Despite an uneasy peace treaty that had lasted for several years, the warlike powers of the Klingon Empire had secretly longed for the means of smashing their sworn enemies in the space Federation. Now, at last, their ruthless leaders were ready for an act of supreme treachery…


A Klingon strike raider makes a surprise attack on the USS Enterprise. Stunned by their audacity, James T. Kirk pursues the raider to the uninhabited planet Seggor, then accompanies a team in an armed shuttlecraft to the surface, but they are unable to locate the raider. A hidden Klingon guard kidnaps crewman Hoskins, dragging him underground to a secret base. There, he becomes a living test subject for the granulator, an experimental weapon. Hoskins is returned to the team via a lift shaft. When Kirk reaches to touch him, Hoskins collapses into a pile of dust.

To lessen risks, Kirk beams up all but Hikaru Sulu and himself. Suddenly they are captured by Klingons and taken into the base. The professor in charge uses the granulator to return Hoskins to normal. He then turns their shuttle to dust, through its force field. The granulator has limitless range and can disintegrate anything. He then gives Kirk an ultimatum: procure the surrender of the Federation, or he will fire their weapon of mass destruction at Earth. Completely demoralized, Kirk and his crew beam up.

Kirk updates his senior officers, but Montgomery Scott won't accept their fate. He tells Leonard McCoy that perhaps Kirk has been hypnotized or duped. Before McCoy can stop him, Scott transports to the surface. Kirk is forced to leave Scott behind and leave orbit. Meanwhile, Scott adjusts his communicator to act as a sonar scanner and locates an access point into the base. He sneaks in, knocks out a guard, and jams the firing mechanism before he is discovered. He then scrambles to the surface and calls for emergency beam-out. Klingons target the Enterprise, but the weapon backfires, destroying itself, the base and a dozen square miles of the surface. Kirk says he would have court martialed Scott for mutiny had he not just saved the Federation.
