* '''''DRAGON-TIER CHEAPIES'''''. Not only are they the [[OmnicidalManiac strongest]] [[http://mugen.wikia.com/wiki/Cheapie type]] [[GodOfEvil of characters]] to '''ever''' exist, but they can also '''literally''' '''''[[GameBreaker destroy your game]] [[TheFourthWallWillNotProtectYou and your computer!!]]''''' There is a supposedly confirmed one named "Mathrus", appearing as a [[VideoGame/WorldOfWarcraft Felhound]]... and it apparently does destroy your computer. Thankfully, none of them are public for download, and very likely never will be. There are, however, [[https://www.youtube.com/watch?v=thki8txLb9s actual "gameplay" videos]] [[https://www.youtube.com/watch?v=1DVOs5-WHrQ of cheapies]] that hack the computer to force a win (including [[https://www.youtube.com/watch?v=NIcrdXd7Bsk one of Mathrus' "brother"]]), and they're ''not'' pretty.
* Kyouki (not to be confused by the unrelated porn-character Kyouk'''o'''). Everything about Kyouki. An emaciated, towering monstrosity with a mask-like face, black sockets for eyes (except in its win-pose), and matted black hair. When you KO it, it disintegrates into a swarm of possessed-looking baby dolls, followed by a cutscene of it getting closer and closer to the screen, ending in a static image of its mask-face. It then reappears, with YOU KO'd instead as it does its disturbing win-pose.

* [[https://youtu.be/TNQyiEyBf7I?si=j9oofI_BdhuPhaKe Sadist ZERO Final at level X (unknown)]] may be something close to that.

* There are a surprisingly huge amount of characters based on content from kids' media that are compatible with ''Franchise/MortalKombat'''s fatalities.

* WalGarutRuf: A lost and rather bizarre edition of Ronald McDonald, who functions as a boss character with the anatomy, attacks and movements similar to those of an arachnid.

** As a supposed and unconfirmed demonstration of how far this character's level of power can go, Ced Zodium (a well-known creator of broken characters in the MUGEN community) was part of an alleged group of Russian MUGEN content creators (including Urak) who were totally dedicated to creating dragon-tier characters and anti-malware characters (according to his own words, there are three more dragon-tier characters produced by this group, known as Doxa, Wendel and Louvan) which operated via the Skype application. It was precisely from there that he obtained a copy of the original version of Mathrus, and decided to test it on a computer at a school he was studying at, sneaking into the school's information room and infiltrating one of the computers to test it. According to him, the test caused a blackout that knocked out the power grids in his town, leaving the entire town without electricity for 24 hours. Ced managed to escape before he was captured.

* [[https://youtu.be/LH5j6K8YlSI?si=qsxMS4Yr20wJBKO3 Baron Dimanche]] & [[https://youtu.be/zWOgN_anpRI?si=mZPjgyMn0dQBRCNK Baron Mercredi]] from Legend of Sebas. They are extremely powerful characters who, upon defeating their opponents, present disturbing clips taken from horror movies and montages taken from the internet. As well as their disturbing voice-overs.

* The character XXXXXXX (a supernull-style character who resembles Kirby's character Zero) was inspired by a nightmare his creator had.

* Mathrus in general. This was (supposedly) a very powerful dragon-tier character and a supervirus with a redman's reach that was created by a Russian hacker known as Urak.

* Multi Colonel. This is an extremely powerful edition of Colonel Sanders made by MatsudaSpecial (the same creator of Dark Exellent Donald), and one of the most obscure with little information known. According to reports from community users, this character was shown in some videos posted on the NicoNicoDouga website between 2014 and 2015, and has even been used in a style contest tournament.

** The most famous example is DG's ''Franchise/ThePowerpuffGirls'' (specifically, the 1998 one), where [[https://youtu.be/Y8SQQsJJxNY?si=Y6WfTW5tNi_R9Pxn Bubbles, Buttercup]] and [[https://youtu.be/3PaB1ZTd9_s?si=7Mkc5CvA7Vk9gT2u Blossom]] having zero qualms on straight up ''murdering'' their opponent if they wanted to and in a rather gory fashion. [[note]]To put this in perspective, the only time the Girls have shown this kind of brutality, at least canonically, was their 1992 pilot ''Whoopass Stew''.[[/note]]

* Dark Donald and Dark Excellent Donald have actual [[JumpScare screamers]] coded into them upon starting the second round, first by deceiving the player by fighting (or controlling) a different character, followed by a [[ScreamerPrank scary picture with the loud scream]] like the Exorcist girl from the Scary Maze Game or Smile.JPG after which the battle resumes as normal.

*** Even all ''this'' is surprisingly tame compared to the following: yes, you can pair [[https://youtu.be/lBAjVrY33q0 two Giygases to]] [[https://youtu.be/HbddyhIAyd0 fight each other]], which would increase NightmareFuel tenfold. Sweet dreams!

* A tamer example, but one of RAHLONNIR's [[ComicBook/ThePunisher Punisher]]'s [[https://youtu.be/4GgEies6rKY supers]] has him run over opponent with his vehicle, take them inside said vehicle, and then starts to ''rip them apart'' with his gloved hands, complete with gory sound effects.

* ''Nijikaku'' is an incredibly bizarre Japanese MUGEN fullgame based off of 2chan and its various memes. While most of the game is fairly tame despite its oddness, the game has some very grotesque, violent and downright disturbing imagery as well. Examples of this include Gurocure, a team-based character that can make its opponent slowly fade away into nothing with ''some of the creepiest piano music ever'' and can also ''feed them to a monster made out of what is presumably flesh'', Sattin, a parody of ''VisualNovel/{{Tsukihime}}'''s Satsuki that uses a ''jump scare'' in one of its supers, then '''crushes its opponent''', and Manamana, who has a super where she ''[[GroinAttack hammers nails into her opponent's penis]], on-screen''. ''And this is only scratching the surface of some of the more disturbing parts of the game.''

* The_None's [[VideoGame/{{Mother}} Giygas]]. Put simply, if you once feared but then grew desensitized towards Giygas, this version of him will ''rekindle'' that fear, permanently. He can summon stuff like [[VideoGame/HalfLife headcrabs]], as well as employ his endless repertoire of PSI-powers, at seizure-inducing levels and plays horrible sound clips of agonized wailing and screaming at completely random intervals. One of his special moves involve throwing the victim into one of two stage fatalities from [[VideoGame/EternalChampions Eternal Champions: Challenge From The Dark Side]] (they function like [[PressXToNotDie quick time events to make it easier]]), and they are signaled by a red flash picture of [[WesternAnimation/SpongebobSquarepants Speng]][[GoneHorriblyWrong bab]]. When a new round starts, it looks as if you're fighting someone completely different, like [[Franchise/TouhouProject Youmu]], but SPENGBAB IT'S A TRAP. And when he wins...he'll either flash {{Gorn}}y stuff at you, a Music/MichaelJackson pic that [[ScareChord GOES MAD]] and...[[http://knowyourmeme.com/memes/smile-jpg Smile.JPG.]]
