History Monster / Digimon

** If anything, [=IceDevimon=] in DigimonFrontier is just as bad, if worse! Here he's an AxCrazy killer whom even the current BigBad didn't want anywhere near him!

** ''[[BackFromTheDead Then he comes back]]'' and proves to be [[TheManBehindTheMan the mastermind of everything in the second season]]. He'd played on Oikawa's sadness and despair to use him as a pawn, [[TheCorruption his corrupting influence destroying Oikawa's body from within]]. [[HumanResources Using kids]] to incubate his ''new'' power source wasn't nice, either, but the ''real'' reason Myo is seen as nigh-Kurata-level evil is what he did once [[YouHaveOutlivedYourUsefulness he didn't need Arukenimon anymore]]: he subjected her to [[HighOctaneNightmareFuel a painful and horrible death, while reading her mind and doing everything she feared he'd do to her in that order]]. The poor DarkActionGirl ''hadn't'' failed him; this was purely [[ForTheEvulz for the hell of it]], and not only that, he infamously claimed to have been kinder with her because she was a woman. And when her DoggedNiceGuy Mummymon tried to avenge her, Myo gleefully incinerated him. Other DigimonAdventure villains can be {{Bad Boss}}es and tend to be {{Card Carrying Villain}}s, but Myotismon's sadism is unparalleled - or was. (Yes, ''[[UpToEleven Kurata is worse.]]'')

** A very good showing of just how horrid this guy is would be the reaction the heroes have to him in the last phase of the final battle. [[spoiler:Marcus finally gets [=ShineGreymon=] to reach [[SuperMode Burst Mode]] and turns the tables on him. Cue [=ShineGreymon=] shooting Kurata one of the most hate filled {{Death Glare}}s in anime history while everyone else is [[AndThereWasMuchRejoicing cheering for Kurata's demise]] before Marcus and [=ShineGreymon=] put Kurata down while he's begging for mercy. Normally, trying to kill someone off whose begging for mercy is the job of the AntiHero or in a BigDamnVillains moment, and if the hero does it, it's normally a sign that they've crossed the line. Kurata is such a horrible, ''evil'', terrible excuse for a human being that finishing him off while he's begging for mercy is a [[KickTheSonOfABitch completely acceptible action]].]] Basically, Kurata is the digimon equivalent of [[MegamanZero Doctor Weil]].
* Speaking of Myotismon. (Spoilers for the most WhamEpisode filled arcs of the first two seasons ahead.) This guy '''was''' the most psychopathic villain of the series until Kurata came calling. First he took in Gatomon under his wings in order to [[BreakTheCutie abuse and assault her]] to the point she became his [[TheDragon loyal killing machine]]. He tortured his IneffectualSympatheticVillain minion Demi Devimon for petty reasons, entered the human world and [[TheTokyoFireball destroyed much of Tokyo]], killing several of his hench-mon along the way [[YouHaveFailedMe for the slightest failure]] ([[BadBoss he]] ''[[BadBoss very]]'' [[BadBoss seldom leaves a minion alive, in fact]]), kidnapped almost every family in Odaiba and forced Gatomon to identify the children of said families as her partner in his search for the Eighth Child or he would kill them all, and killed poor Wizardmon (okay, Wizardmon had [[HeelFaceTurn turned on him]], but killing a {{Woobie}} will earn you major {{Jerkass}} points.) Any minions he hadn't already killed were cannibalized to fuel his SuperMode, and he was stopped just in time to prevent the entire population of Odaiba from becoming dessert.

The poor DarkActionGirl ''hadn't'' failed him; this was purely [[ForTheEvulz for the hell of it]], and not only that, he infamously claimed to have been kinder with her because she was a woman. And when her DoggedNiceGuy Mummymon tried to avenge her, Myo gleefully incinerated him. Other DigimonAdventure villains can be {{Bad Boss}}es and tend to be {{Card Carrying Villain}}s, but Myotismon's sadism is unparalled - or was. (Yes, ''[[UpToEleven Kurata is worse.]]'')
* [[DigimonAdventure Piedmon]] is a psychotic MonsterClown who doesn't give a damn about life at all. He ruthlessly kills a large amount of the team's allies in brutal ways and when the Digidestined finally face him down he savagely beats them down before [[AndIMustScream turning them into living keychains]] for him to toy with. The sequence where he hunts down the kids and their digimon one by one before transforming them, all while laughing with sadistic glee and mocking the two youngest team members (who he saves for last) is surprisingly frightening.
** Seems the writers are aware of how big of monsters these two are, Piedmon and Myotismon are the only two ''DigimonAdventure'' villains who ultimately suffer a FateWorseThanDeath as well. Where Myotismon is ultimately killed DeaderThanDead (having his ''soul'' destroyed), Piedmon is sucked into [=MagnaAngemon's=] Gate of Destiny, a portal to a dimmension from which he can never escape, and Digimon are pretty much immortal baring being killed outright.
* While not be on par with Myotismon or Piedmon in terms of sheer evil, Machinedramon also counts. Most {{Killer Robot}}s are unfeeling killing machines, Machinedramon's CreepyMonotone would imply this applies to him to. But its the things he actually says that pushes him into this. Practically everything he says shows he's a cold, calculating sadist who loves killing people. The most chilling line he has in the entire show is telling Kari, a little girl and one of the youngest Digidestined, that he is going to kill her in ''the most painful way he possibly can''. And the combination of his sadistic lines and his CreepyMonotone make almost everything he says HighOctaneNightmareFuel. While he's not the worst CompleteMonster in Digimon, he certainly makes the list.
* Tactimon of ''DigimonXrosWars'' bears special mention, in that he was prepared to ''torture a child to death'', as opposed to a quick, painless execution (not that that's any better, it just shows how sadistic Tactimon is). As if that wasn't bad enough, he's a full follower of the WeHaveReserves mantra, and has no compunctions about sacrificing his own subordinates for the sake of maintaining his supposedly perfect battle record. Another example is [=NeoVamdemon=], an {{Expy}} of Adventure's Myotismon, who [[spoiler: absorbs a great number of innocent Lopmon in order to remain immortal, while also absorbing Kiriha's partner [=MetalGreymon=] into himself,]] along with Lillithmon, who orchestrated the fall of the Goddess' Warriors in the Sand Zone and then ''laughed'' about it to its sole survivor.

* A minor example, but [=IceDevimon=] of ''DigimonTamers'' certainly counts. Not content to merely load their data, he [[NightmareFuel keeps the frozen remains of the Digimon he killed as a kind of trophy gallery.]] Notably Ruki, who to this point had been rather ruthless regarding Digimon, [[EvenEvilHasStandards is completely horrified]].
* An underrated but important example is Millenniummon of the ''DigimonWonderSwanSeries''. He is responsible for the cataclysmic events of the Digimon universe, mainly the Adventure/Zero Two verse such as releasing Apocalymon.
** Also when Milleniummon was destroyed, his data turned into Dark Spores and one buried itself into Ken's neck, exerting its influence on him. Since then, it grew within Ken and was later harvested and implanted into other children by Yukio Oikawa, meaning that Milleniummon is so evil that his data can corrupt anyone and turn them into insane and hateful beings and Milleniummon is indirectly responsible for some of events in DigimonAdventure02. Also on the subject of realeasing Apocalymon: in ''DigimonWonderSwanSeries'' it is stated that Apocalymon's existence brought Devimon, Myotismon and Dark Masters into existence, this means that by releasing Apocalymon, Millenniumon is responsible for everything that goes down in DigimonAdventure and DigimonAdventure02 and is responsible for creation for some of complete mosnters in this page.

* Professor Akihiro Kurata in ''DigimonSavers'' is the most despicable human villain to ever appear in the ''Digimon'' franchise. While Ken from DigimonAdventure02 didn't think [[VideoGameCrueltyPotential that he was doing anything wrong]] (and may or may not have been under MoreThanMindControl), Oikawa was under MindControl in a significant way, and Yamaki from ''DigimonTamers'' was a WellIntentionedExtremist who ultimately had a HeelFaceTurn, Kurata's only goal is to TakeOverTheWorld and sadistically destroy all Digimon because of a petty grudge. Creating the Gizumon, mechanical monstrosities that make other Digimon DeaderThanDead by stopping them from reincarnating like usual, and experimenting in creating half-Digimon hybrids were only the start. Creating a weapon of mass destruction to kill thousands of Digimon in one shot, forcing the TeenGenius on the heroes' side to a FaceHeelTurn by threatening to kill his IllGirl little sister, trying to replicate his experiments on said IllGirl, and finally awakening a mighty Demon Lord and merging with it to destroy all of his enemies... well, that should give you an idea of how loathsome this guy is.

* Apocalymon, the true BigBad of DigimonAdventure, may or may not qualify for this trope. Although he came out of nowhere, was rather LaughablyEvil LargeHam in the dub and didn't have much screen time, he is still the cause for all chaos and trouble in Digital World, is the master of Dark Masters and his mere ''presence'' caused chaos. If he had more screen time and was less Laughably Evil he could have been ''worse'' than all other Complete Monsters above. He may be worse than them since he is the evil incarnate and we just didn't see anything that puts him on the par with all others in this page.

* Apocalymon, BigBad of DigimonAdventure had the ''potential'' to be this trope and possibly had the potential to be much ''worse'' than Myotismon, Piedmon or other [[CompleteMonster monsters in frachise]], however his character was wasted by making him rather LaughablyEvil and LargeHam and came out of nowhere. Why he had the potential to be CompleteMonster? Because he was the one who caused all the trouble in Digital World, was master of Dark Masters and his mere ''presence'' caused chaos and destruction everywhere. If he wasn't LaughablyEvil LargeHam and had more screen-time he would be this trope. This also overlaps with TheyWastedAPerfectlyGoodCharacter. However he could be actually ''worse'' than any other villain (even Myotismon and Piedmon) as he is the evil incarnate and we just didn' see anything he did that puts him with Myotismon, Piedmon.

** He also powers his city by enslaving Numemon to run his machines and kills Andromon who tried to help the heroes.
*** Err... no, he didn't kill Andromon (who actually survived to help out in the battle against Piedmon), but he ''was'' willing to do so. And his murder of all the Numemon (who tried to stop him) gives him the ''biggest'' on-screen death-count of ''any'' villain in the franchise.
