Forbidden World

Astronaut Mike Colby is rudely awakened from suspended animation by his robotic pilot and sent by the Federation to the remote desert planet Xarbia, tasked with resolving a delicate problem that’s arisen at a genetic engineering lab. When he and his faithful robot sidekick arrive, the intergalactic troubleshooter learns that the research team, while attempting to synthetize an extraordinary new food source, has created an experimental lifeform designated “Subject 20”. What they don’t tell him at first is that this rapidly mutating creature was derived from splicing human DNA.

Beyond possessing a disturbing aggressive streak, this “metamorphic mutant” turns out to be intelligent as well, even devising specific plans to “use” the human beings around it. Colby plans to put his personal motto (“If it moves and it’s not one of us, shoot it!“) into practice and resolve the problem right off the bat, but he finds himself surrounded by recalcitrant scientists who view the “metamorph” as an interesting research subject.

His plan of action frustrated, Mike instead consoles himself with the station’s lovely female staff.
Meanwhile, it doesn’t take long for the creature to mutate into a huge insect-like being with an insatiable appetite…
