History NightmareFuel / StargateSG1

** And Reese. A robot in the form of a young, pretty and apparently entirely innocent girl with the emotional maturity of a five year old child... who created the Replicators, calling them her 'toys.' Which she can control. And she responded to attempts to destroy them (and her) by teaching themselves to defend themselves and her, as well as replicate in the way they're so famous for, transforming them into a nigh unstoppable multi-galactic scale menace. Reese herself nearly destroys the SGC with her inherent technopathic abilities, her control over the Replicators and pretty much just the stuff she was given in her isolation room. Her DissonantSerenity as she unleashes the Replicators on her guards, and then the rest of the SGC, is nothing short of chilling.

* How about being [[KillItWithFire BURNED ALIVE]] by die hard Ori followers because you happen to be in a locals body? Obviously not a good way to go if you happen to be a normal person.... but the process in effect does kill two people. The First is obvious, but you're the second as your mind is linked, and therefor, you die as well.

* The Asgard can come off as this before they've been properly introduced, since they are the spitting image of [[TheGrey the Greys]]. Once they're more established as the Stargate Universe's BigGood, some people see them as UglyCute.

* See CruelAndUnusualDeath. Even if it doesn't happen onscreen it is highly disturbing.

* The fate of the poor Egyptian scribe that was chosen to be Apophis host, being forced to watch as Apophis comitted countless atrocities across the galaxy for thousands of years, with no control of his body. When he finally regains momentary control while Apophis is sick and dying, the man begs miserably in ancient Egyptian, with Daniel being able to translate, that he's been aware and helpless all this time, and he wishes for nothing but death and to be buried by egyptian custom. He doesnt even get that, Sokar eventually forces SG-1 to return Apophis to him so he can keep him alive and torture him. Its not until Apophis final death that the unnamed scribe finally knows peaceful oblivion.

* The Ori and possessed Doci. If the concept of being burned alive for not worshiping isn't nightmarish enough, that fire skull form is.

* The Ancients and their status as AbusivePrecursors. They arent ACTIVELY malevolent, but have left enormous messes behind during their time in the physical universe, especially the Replicators and the Ori, and refuses to help against them because of their sudden decision to cling to a Prime Directive. Thanks, would have been nice if you had stuck to that thousands of years ago.

* The Goa'uld themselves. These foot-long snake-worm-things with fins will take [[PuppeteerParasite complete control of your body]] and use it to live like a monster for thousands of years. They have access to all the original person's memories, so if they want, they can impersonate that victim almost seamlessly.
