it begins killing the personnel at the station, starting with Jimmy, who was charged with cleansing the subject lab of the dead animal test subjects. As Subject 20 continues to kill most of the station crew, the reason for the deception is revealed. Subject 20's genetic design incorporates human DNA, and its method of killing is to inject its prey with the Proto B DNA strain which then proceeds to remove all genetic differences within specific cells. The result is that the victim's living body slowly erodes into a gelatinous pile of pure protein which Subject 20 consumes for sustenance. After its final mutation, where the creature evolves into a huge insect-like being with a large mouth full of sharp teeth, the creature is slain when it eats Cal's cancer-ridden liver, its body genetically self-destructing from within. Mike and Tracy are left as the only survivors from Subject 20's rampage.

Reception Review aggregation website Rotten Tomatoes gives the film a rating of 60% based on reviews from 5 critics. The Los Angeles Times called it "lively, amusingly gruesome." Home media On July 20, 2010, Shout! Factory released Forbidden World on both DVD and Blu-ray Disc. The DVD is a 2-disc set.
