* His description of what the real effects of [[VideoGame/StarWarsBattlefrontII Operation: Cinder]] would be. Storms wouldn't be the worst of it. The plasma would heat the sky, and to quote the video: "A warmth that would gradually grow hotter, and ''hotter'', until you found yourself ''boiling alive'', baked to death like you were in the world's largest convection oven, because that's actually where you would be."

* The ''WebVideo/{{Petscop}}'' videos. MAN, OH MAN. The first was bad enough, with him describing in vivid detail the real-life death by suffocation of Candace Newmaker during a "rebirthing" attachment therapy session. But the second is even worse, as it cranks the creepy editing, [[JumpScare surprise jumpscares]] and glitching from the ''Doki Doki'' episodes to a [[UpToEleven whole new level]] and uncovers what seems to be a series of murders and abuse caused by a man named Marvin and how he's the shadow man.

%% * [=MatPat=]'s gallery of executions by elephant in "Why Mario is Mental, Part 2".

* The ending of the theory based around the "Bob" mod for ''VideoGame/FridayNightFunkin''. The whole theory discusses a unsettling ARG where a man created a self-aware AI, which murdered him and his wife and disfigured and rendered his young daughter comatose, all using a mysterious black ooze. [=MatPat=] ends the video discussing the AI, Bob, when it attacks and corrupts him with the black goo. [=MatPat=] is heard gasping and struggling to breathe through the outro, as Bob's hyper-realistic eyes fill the screen and it gloats about killing the host. Even the sponsorship segment after the outro is styled to look like [=MatPat=]'s funeral, with his friends and family mourning in the audience.

%% ** The ''Polybius'' video brings up secret government experiments and coverups.

* His two parts ''VisualNovel/DokiDokiLiteratureClub'' video is noticable glitchy and seemingly haunted by Monika, who even speaks ([[SuddenlyVoiced fully voiced to boot]]) at a few points. The first part has his catchphrase be corrupted into a BrokenRecord that keeps saying [[ArcWords Just Monika]] and the second part, after theorizing that the true threat (or at least the threat of Team Salvato's upcoming game) is none other than Yuri, has her seemingly ''killing'' [=MatPat=] as he's saying his catchphrase before [[TheFourthWallWillNotProtectYou going after the viewer]]!

* Some of his videos that tie into RealLife qualify as this.
** His first ''Five Nights at Freddy's'' video, which brings up a real murder case from 1993.
** The ''Polybius'' video brings up secret government experiments and coverups.
* [=MatPat=]'s gallery of executions by elephant in "Why Mario is Mental, Part 2".
* In his ''Franchise/{{Halo}}'' armor video, he suggests the reason why Spartan succumb to a single melee blow. The hit cuts off the neural interface, and causes the suit to crush the user to death.

* The Try to Fall Asleep theory, delving into nightmare deaths and hallucinations, including two [[SarcasmMode lovely]] anecdotes and real-life deaths.
** If that wasn't unnerving enough, Mat then theorises that Dr Richard Norberg, the therapist who advised the protagonist John Herrin to sleep it off, is a PsychoPsychologist with ulterior motives, with the doctor cutout gaining a black SlasherSmile and reaching out to John Herrin with white gloves. As the episode ends, the camera [[{{Jumpscare}} zooms in on Norberg]] as [[RedEyesTakeWarning his eyes turn red]].

** All the FridgeHorror that comes from his ''VideoGame/WatchDogs'' videos. He doesn't end it with his usual catchphrase, either, highlighting just how serious this is.
---> "'''That''' is the world of Watch_Dogs. That is ''our'' world. And that '''isn't''' a theory: it's a fact."
