4	NightmareFuel in ''Anime/DigimonFrontier''.
5	----
6	* The state of the Digital World due to all the data being stolen to fuel Lucemon's resurrection. It looks like a fruit with multiple bites taken out of it and eventually corrodes into nothing but a black void near the end of the series. Worse is Lucemon planned to do the same to the Earth.
7	* When Takuya turns into his Beast Form for the first time in episode 11, he turns into a mindless berserker, even lashing out at his teammates and comes within an inch of killing Tomoki. The horror in his voice is clear even in the English dub where while his voice is calmer, it's clear the realization of what happened is a true kick to the gut and it's no wonder he's terrified of his Beast Form for a while after that.
8	--> '''Takuya''': (''coming back to himself'') Tommy? ...[[MyGodWhatHaveIDone What did I just do?]]
9	* From episode 21, Kouji TakingTheBullet for Takuya when his plan for Duskmon ends in PunchPunchPunchUhOh was already bad enough, given that he not only [[BroughtDownToNormal returned to human form]] but also was passed out from the pain but in a following episode, Kouji is clearly holding his ribs while trying to rescue the others, meaning that they are at the very least badly bruised and probably worse since his breathing is slightly off as well.
10	* Mercurymon is pretty nightmarish considering he essentially uses his reflection powers to MindRape the heroes with HannibalLecture after lecture by playing on the insecurities and personal demons to push them into the DespairEventHorizon and nearly succeeds if not for the PowerOfFriendship and HeroicWillpower displayed by each hero.
11	** The climax of his character arc has Mercurymon turn into his Beast Spirit form Sephirothmon/Sakkakumon, a mutant Digimon comprised of ten spheres. Initially used to entrap the DigiDestined and engage in psychological warfare throughout the ten areas his spheres are comprised of, Sephirothmon/Sakkakumon soon goes all out on Takuya are toying with him for a bit by manifesting Mercurymon in the Steel Area, the perfect environment for his powers. Bringing Takuya to a cathedral in the Light Zone, Sephirothmon/Sakkakumon produces a copy of Seraphimon's fractal code. After which Mercurymon does of Fusion Evolution with the DNA of the very Digimon he killed with his own attack, becoming ShadowSeraphimon. Not only does this twisted perversion of the Holy Digimon easily beat Takuya as ''both Agunimon and Vritramon/BurningGreymon'', he comes close to actually killing Takuya, even conjuring up a coffin to stuff his body into.
12	* Icedevimon is In-Verse Nightmare Fuel considering he's the Digital World's equivalent of a serial killer who went on a rampage killing and feeding off the data of Digimon until he was captured by an army of Digimon warriors. Not even Cherubimon could destroy the guy and decided to simply seal him away forever under his hideout. Not to mention he's a total Sadist and CombatSadomasochist who delights in killing as many people as possible in the most horrible way possible.
13	** As hilarious as his voice acting is, there's just something chilling about how playfully murderous [=IceDevimon=] from episode 36 is. Even worse, his dialogue implies that those... things in the basement of Cherubimon's castle were the result of him feeding on the data of Digimon that he captured.
14	* Duskmon is actually a {{Deconstruction}} of the ''Adventure'' series. Take a random human child with strong emotions, drag him into your world against his will, and ''make him fight for you''. The logical conclusion? He turns into an insane BloodKnight. Not to mention he's the in-verse nightmarish ImplacableMan who takes down the heroes with no effort and tanks all of their attacks. He ends up being so overwhelming he nearly drives Takuya into a total DespairEventHorizon and actually makes him consider running back to the real world and leaving his new friends behind. The heroes' survival against him was nothing less than a miracle.
15	* Everything related to Sephirothmon/Sakkakumon: A big set of giant Eyeballs, taking the form of the Tree of Life, keeping the heroes inside dimensional pockets, making them confront their own fears, and letting in Cherubimon henchmen to finish the job. But by episode 29, his true scheme is reveled. He was learning everything about the Digispirits techniques and copy them, alongside Cherubimon henchmen techniques. The only way to defeat him was ''improvising'' new techniques.
16	* Lucemon's voice actor in the English dub voiced Izzy in season 1 and 2. For anyone that grew up with those two seasons, they'll recognize that voice anywhere when they hear it in any other character in the later shows. But with Lucemon, they go even further, giving him a more evil tone that's very disturbing. You're basically listening to an evil Izzy at this point and he's ready to blow up entire portions of the Digital World to make all Digimon and likely even ''humans'' his slaves. His Japanese voice actor is also the same one as '''that''' [[Manga/DragonBallZ Freiza]], another monstrous maniac with an obsession of blowing up entire planets and selling them to the highest bidder.
17	* [[TheFourthWallWillNotProtectYou '''You must choose to follow me or be destroyed''']]
