10 Stargate SG-1 Fates Worse Than Death
4. Turning Into An Alien Insect Hive
SG-1 didn't exactly do body horror too often, but the one time they did they very much doubled down on this skin-crawling subgenre of terror.
In one of the most urgent cold opens ever seen, SG-1 arrives on a deserted planet and must flee desperately from an oncoming swarm of vicious alien insects, making their way to The Gate with all the urgency that situation deserves. Although they manage to escape, Teal'c is stung by one of these flying nightmares and, upon his return to Earth, begins exhibiting some horrific symptoms.
Despite his larval Goa'uld usually protecting against illness, it can only hold back the inevitable mutations that the insect sting promises. Whilst Teal'c is literally begging for death, the sting is transforming his DNA into that of the bug, and gradually turning him into a hive of them to burst forth and claim the human race.
Whilst the SGC manages to synthesise an antidote using a sample of the original venom, Teal'c is overcome with an insectoid instinct to find somewhere dark and remote to complete his transformation and escapes the compound. When he is eventually found, covered in sores and almost completely cocooned, it's clear that this monstrosity was only stopped with moments to spare.
