History NightmareFuel / RemnantInferisDoom

* Deag Grav's killing of Fox in Chapter 15. It's so sudden that nobody has time to react to it. Even more so is how the Argent energy tears him apart from the inside, and then Deag slices him in half vertically from his torso ''upwards''.

-->"Team SSSN had thought they had seen the extent of what evil was capable of during the demonic invasion of Haven Academy. How naive they had been."

* In Chapter 27, we discover how horrific were the experiments the SDC was doing with captured Faunus. The most horrific is the one explicitly inspired by ''Film/EventHorizon''. Multiple Faunus were brought to a chamber and exposed to special pheromones, resulting in all of them '''raping and killing''' each other. The goal? To summon a demon with this death orgy, all for the sake of their experiments.

** In Blake's nightmare, the Slayer, in his ''VideoGame/DoomEternal'' suit, kill everyone in the White Fang, including her father and Ilia in front of her. After that, undead White Fang members catch her and just before being killed, she sees Adam's reflection in the Slayer's visor instead of her own.

Take the {{gorn}}y brutality of ''DOOM'', add in ''RWBY'''s CrapsackWorld elements, and let horrors await.

** Yang's nightmare is tamer, but having her stepmother killed in front of her by an Imp's arm that comes out of nowhere is very disturbing.

** Weiss dream is that she was defeated by the Arma Gigas and had to submit to her father's will. After that her father, flanked by Classic Doom's Imps, reveals that he sold the world to the demons. Just before being killed she had to watch Atlas being destroyed by Hell.

** Ruby's is probably the worst of them. She wakes up naked, surrounded by blood, flesh and guts. She then hears a voice behind her, which turns out to be her mother. Before she can run up to hug her, it's revealed that ''this'' Summer had her eyes bored out of her sockets and has a giant, bloody hole in her stomach, indicating that her womb was '''torn out of her body'''.

* Had the rest of it’s kind actually listened to Deag Grav, ''they would have won!'' Had they killed the Slayer while he was sealed away as it suggested, there would be no one to stop Hell.

** When she sees Jacques holding the Slayer's helmet, her first instinct is to ''slice off all his left hand's fingers'' and leave him in pain. She then picks up the Slayer's helmet and just... smiles. As if she's ''proud'' of what she just did.

"Not Slayer, no. '''Reaper'''."

* Deag Grav's killing of Fox in Chapter 15. It's so sudden that nobody has time to react to it. Even more so is how the Argent energy tears him apart from the inside, and then Deag slices him in half from his torso ''upwards''.

* Deag Grav itself, the hell priest that tainted the Wraiths, turning them into living batteries for Hell, merged Argent D'Nur with Hell, and planned the trap that captured the Slayer, is the main threat to all Remnant. He has no problem with dirty tactics, including using dead bodies to hide himself before attacking (once in the cathedral and the second in the old ruins, killing Fox). He also doesn't give any chances to his enemies. In fact, he was the only one that objected to the idea of keeping the Slayer alive in the sarcophagus and despises the Dark Lord of the Fourth Age for punishing him for the Slayer's rampage and denying his ascension to a Baalgar, to the point of calling him ungrateful when the Lord called him in the Argenta ruin.

** Marrow, an Atlas student, was just in his dorm before, according to VEGA, being teleported to the lab. If they are willing to kidnap an Atlas citizen and can do so without even leaving the lab, [[ParanoiaFuel who is safe]]?

** They also capture team SSSN and torture them for answers. Team SSSN was just in the wrong place at the wrong time, having been hunting demons that wandered into the areas nearby the facility. Nobody, neither human, Faunus, young, or old, is safe from them.

Multiple faunus were brought to an chamber and exposed to special pheromones, the result was that all of they started raping and killing eachother, and the goal: to summon an demon with this death orgy.

* The SDC slave labor of Faunas is outright horrific in how brutal it is. They don't just enslave them and force them to work in mines or anything like that. They use them as ''target practice'' just to test their newly developed weapons.
