** [[Manga/MegaManNTWarrior2001 2001 manga]]:
*** Volumes 1-2: [[MadScientist Dr. Wily]] is the head of the terrorist organization known as World Three, and the first BigBad of the series. A [[MisanthropeSupreme bitter, misanthropic old man]] who believes that humanity is ugly, stupid, and deserving of destruction due to his robotics research being ignored, Wily wishes to bring about the end of Net Society itself. To that end, he oversees a number of terrorist attacks that endanger thousands of innocents, such as having a school set on fire; trying to [[MindRape painfully brainwash children]] into becoming World Three's slaves; and trying to demolish a Metroline's security network in order to put its passengers at risk. After obtaining the powerful Life Virus, Wily causes an outbreak of chaotic accidents all across Dentech City before hijacking all of the world's military satellites, which he proceeds to use in an attempt to annihilate major cities around the globe with missiles. [[AdaptationalVillainy Lacking the redeeming qualities]] of his game and anime counterparts, this incarnation of Wily dies hateful and unrepentant, utterly hell-bent on killing millions of innocents over a petty grudge.
*** Volumes 7-9: The obscenely sadistic [[EvilCounterpart MegaMan DS]] is a Darkloid born from the original Mega Man's feelings of hate and anger, and proves to be among his most threatening foes. Obsessed with wanting to fuse with the powerful Navi Bass, DS seeks to make Mega Man hate him with all his heart so he can utilize his hatred as the energy needed to make the fusion a success. To do this, DS commits a slew of horrible crimes such as slaughtering two companies of military Net Navis and [[FrameUp framing]] Mega Man for the act; converting his friend Guts Man into a hateful berserker against his will before forcing him and Mega Man to [[InvoluntaryBattleToTheDeath fight to the death]]; and trying to have his ally Shade Man try to [[RevengeByProxy murder his human partner Lan]] in front of him. After gathering enough hate energy, DS fuses with Bass and opens up an enormous dark hole, looking to swallow the Net and its denizens in pure darkness itself. A monstrous psycho with no moral boundaries whatsoever, DS crosses lines even his fellow Darkloids don't and has no problem [[ChronicBackstabbingDisorder betraying his own allies]], such as provoking Mega Man into brutally killing Shade Man, and forcibly devouring the essence of his loyal partner Laser Man for a power boost.

*** Season 3/''Stream'': [[KnightTemplar Slur]] is an arrogant, zealous alien Navi and [[TheDragon the chief servant]] of the godlike program Duo. Tasked with distributing potentially dangerous Asteroid Navis across Earth to gauge if the planet is a potential threat that needs to be wiped out, Slur's [[FantasticRacism hatred for humans]] leads to her gaming her master's system in her favor. She goes out of her way to distribute Asteroid Navis to people guaranteed to abuse them, and nudges them into doing so while occasionally painfully deleting the Net Navis they already have. Slur's machinations cause a number of disasters to happen, such as the planet almost being devastated by a [[TheFamine famine]]; people being horrifically [[TakenForGranite turned to stone]]; a [[ColonyDrop meteor nearly flattening a city]]; and a number of near-mass murders on top of that. When the Cross Fusion team tries to stop her, Slur simply mass-distributes Asteroid Navis at a quicker rate and overwhelms them with chaos and mayhem around the globe in hopes of giving Duo the final push he needs to [[EarthShatteringKaboom destroy the planet]]. Despite claiming to be protecting the universe, Slur's motivations ultimately boil down to an obsessive, selfish desire to [[TheSocialDarwinist cull any and all life she deems inferior]].

** [[MadScientist Dr. Albert W. Wily]], thought long dead, is, in truth, the GreaterScopeVillain of the entire series. With nothing resembling his more honorable traits from [[VideoGame/MegaManClassic the Classic series]], Dr. Wily created [[Characters/MegaManXZero Zero]] as a means to finally create a robot strong enough to destroy Mega Man, and engineered the creation of the Maverick Virus, turning Reploids who were infected to violence and murder. Wily integrated himself into the virus itself and fostered countless amounts of death and destruction, most notably causing the fall of the once-noble Reploid [[Characters/MegaManXSigma Sigma]] to ambitious evil with thousands killed in his mission, and even nudging Sigma into trying to cause the fall of the colony of Eurasia to spread the virus further, which would consequentially kill off almost all mankind.
** ''[[VideoGame/MegaManXCommandMission Command Mission]]'''s "Chapter 3: The Paper Hero": The Reploid [[WardensAreEvil Silver Horn]] sticks out as a sadist on a perpetual power trip lacking in [[WellIntentionedExtremist any of]] his Rebellion army compatriots' [[AntiVillain redeeming qualities]]. Warden of the Tianna POW camp, Silver Horn viciously kills many dissenting Reploids himself during the Rebellion's takeover of Giga City, personally torturing the famed hero Steel Massimo into a limbless, barely-living heap and keeping his mangled body underneath the camp. Forcing the Navigator Reploid Nana into acting as a sysop for the camp under the threat of executing all of the [=POWs=], Silver Horn's response when he's finally confronted is to [[WouldYouLikeToHearHowTheyDied gleefully reminisce on his torture and eventual murder of Steel Massimo]] to his successor and revealing his ideals that [[TheSocialDarwinist the weak only exist to serve the strong]].
** ''[[VideoGame/MegaManMaverickHunterX Maverick Hunter X]]'' & ''[[Anime/TheDayOfSigma The Day of Σ]]'': [[Characters/MegaManXSigma Sigma]] himself is the leader of the Maverick uprising, and a dangerous madman obsessed with unleashing Reploidkind's true potential. [[FallenHero Once the respected commander of the Maverick Hunters]], Sigma would orchestrate the hacking of enormous industrial robots and unleash them on cities, allowing them to kill plenty of humans and Reploids alike before mobilizing his Hunters to shut them down. When [[Characters/MegaManXX X]] and [[Characters/MegaManXZero Zero]] expose him as a traitor, Sigma decides to test the pacifistic X's resolve by using Zero as a HumanShield and goading X into killing him by shooting through his friend. When X can't bring himself to fire, Sigma nearly kills Zero and goes on to annihilate the highly-populated Abel City with a missile bombardment. A merciless lunatic who's willing to abuse and kill his fellow Reploids in his bid to speed along their evolution, Sigma can only laugh maniacally over the bombed-out ruins of Abel City as he gleefully anticipates the coming battle against X.
** ''[[VideoGame/MegaManZero Zero]]'' series: [[Characters/MegaManZeroWeil Dr. Weil]], [[NamesToRunAwayFrom Dr. Vile]] in Japan, only appears in a few games, yet is notable for being one of the evilest characters in the entire franchise. Following the peaceful resolution of the Maverick Wars by the sapient super program, the Mother Elf, Weil decided that Reploids needed to pay for their crimes. Weil corrupted the Mother Elf and her children, triggering the Elf Wars, which resulted in the deaths of 90% of all Reploids and 60% of all humanity. Defeated, exiled, and transferred into an immortal mechanical body for his crimes, [[FateWorseThanDeath for no execution would sufficiently pay for the suffering Weil had caused]], Weil eventually returned 100 years later, consumed with a thirst for vengeance directed at all life for the perceived crimes against him. Weaseling his way into becoming the supreme ruler of Neo Arcadia, Weil turns it into a [[DystopiaJustifiesTheMeans dystopian hellhole]]. When he [[CrushingThePopulace breaks his citizens]] to the point where they're desperate enough to risk escaping into the wastelands to form their own colony, Weil decides to obliterate their new home with a KillSat called Ragnarok. When Ragnarok is disabled, Weil attempts to [[ColonyDrop drop it upon the colony]] so he can kill everyone in the region. Even death doesn't erase Weil's blight, as his spirit lives on in [[VideoGame/MegaManZX Model W]], manipulating both Serpent and Master Albert into subsequent campaigns of Armageddon.
** ''[[VideoGame/MegaManZX ZX]]'' & ''[[VideoGame/MegaManZXAdvent Advent]]'': [[AGodAmI Master Albert]] is the true villain of the ''ZX'' duology, a man whose delusions of godhood were so intense he appropriated the ruins of Ragnarok to create Model W, the most ruinous Biometal in existence. Master Albert has arranged for every single calamity in the duology, from organizing Maverick raids that leave only a few survivors per attack, to manipulating those same survivors into merging with Biometals to manipulate them into killing each other all off in a plan he calls the Game of Destiny. One of his pawns was Serpent, the BigBad of the first game, who nearly kills thousands more as Albert's UnwittingPawn. Albert plans to use the final survivor of these games to activate the full power of Model W, so he may achieve godhood and consume the world to remake it anew [[InTheirOwnImage in his image]]. Master Albert also subjects his two CoDragons, Pandora and Prometheus, to [[BadBoss monstrously awful treatment]], permanently merging them with their Biometals and finally consuming them both when they try and fail to betray him. [[NotSoWellIntentionedExtremist Despite his musings]], Master Albert ultimately commits every atrocity [[ItsAllAboutMe because of his monstrous ego]], and as such feels it's his godly right to cleanse the world and pick up the pieces anew.
* [[Manga/MegaManX Manga]]:
** [[Characters/MegaManXSigma Sigma]], the BigBad behind the Maverick Wars, is [[Characters/MegaManXX X]]'s most personal foe. Consumed by feelings of betrayal and bitter disillusionment with the humans that he once protected, Sigma led a [[KillAllHumans genocidal campaign against humanity]] to create an empire where only the Reploids who embraced his tyrannical rule would be allowed to exist. To pave the way for his [[NotSoWellIntentionedExtremist so-called utopia]] to become a reality, Sigma obliterates entire cities, executes hundreds of dissenting Reploids, and orders his men to kill as many as possible by any means necessary. Following his initial defeat at the hands of X, Sigma assembles a new army to wreak more havoc--including launching a missile that wipes a nation off the map--and hatches a plan to swallow the world in darkness by distributing a chip that [[HatePlague makes innocent Reploids go berserk]]. Using his own [[TheVirus Sigma Virus]] to infect Dr. Doppler and corrupt his ideals of pacifism, Sigma uses him as a tool to start yet another rebellion that takes countless more lives. Despite not being present in the Great Repliceforce War, his agent reveals that Sigma was responsible for the FalseFlagAttack that ignited the war in the first place. A madman who desired a totalitarian world in his own hands, Sigma is forever remembered as the face of Reploid supremacy and the worst enemy of humanity.
** ''[[VideoGame/MegaManX1 X1]]'' chapter 11 & ''[[VideoGame/MegaManX3 X3]]'' chapter 10: [[BoomerangComeback Boomer Kuwanger]] is one of the [[Characters/MegaManXMaverickBosses original Maverick Hunters who followed Sigma's example and betrayed humanity]]. Participating in the genocidal war solely because he was bored with his life as a hero and wanted the [[PsychoForHire chance to kill innocent people]], Kuwanger is left in charge of a WeaponOfMassDestruction and tests it on a populated city before trying to annihilate the entire country. Revived by his brother Gravity Beetle, Kuwanger teams up with him in bombarding another city, taking advantage of Dr. Doppler's rebellion to keep killing more and more people.

*** [[EvilOldFolks Serges]]--all but stated to be the reincarnation of [[VideoGame/MegaManClassic Dr. Wily]] himself--is Sigma's MadScientist and the leader of the X-Hunters, a Maverick task force under the direct supervision of Sigma. [[PsychoSupporter Fully supporting]] Sigma's cause as a way to defeat the successor of Mega Man, Serges closely assists Sigma in his plans to exterminate humanity and personally purges lesser Reploids. Upon being defeated by X, Serges tries to activate a system of [[KillSat killer satellites]] to fire lasers at multiple countries out of sheer spite, willing to throw the whole world into chaos if it meant winning and mocking the legacy of Dr. Light.
*** Chapter 3--"Duel": [[PlayingWithFire Flame Stag]] was one of the few Mavericks who survived the first rebellion and joined {{the remnant}}s of Sigma's army. A vicious PsychopathicManchild even during his days as a Maverick Hunter, Flame Stag mercilessly bullied lower-ranked soldiers to the point that X himself had to reprimand him for his behavior. Holding a petty grudge against X for standing up to him, Flame Stag sided with Sigma to fight X in battle and have his {{revenge}}. Assigned to a facility inside of a volcano, Flame Stag gladly goes along with a plan to cause chain eruptions around the world and [[TheNightThatNeverEnds block the sun]] just to face X again.
** ''[[VideoGame/MegaManX4 X4]]'' chapters 6-7: [[AnIcePerson Frost Walrus]] is a sadistic Reploid war criminal that not even the Repliforce can tolerate. A convicted murderer who joined the military [[SociopathicSoldier for the violence]], Frost Walrus sees the MilitaryCoup as an opportunity to indulge in random acts of cruelty. When the Great Repliforce War begins, Frost Walrus takes several Reploids to his torture room and watches them slowly freezing to death but unable to do anything about it, later disposing of his victims by HuntingTheMostDangerousGame--it's in the aftermath of this massacre that X learns the true extent of his atrocities: Frost Walrus is a prolific SerialKiller who likes to keep the corpses of famous Maverick Hunters as morbid trophies in what he calls the "Room of the Wild Ones", so bad are his crimes that General himself steps in to personally execute Frost Walrus.

* The games: [[CardCarryingVillain The proudly and blatantly villainous Dr. Regal]], the BigBad of the fourth and fifth games, is the head of the Netcrime syndicate Nebula, and gleefully strives to prove his belief that [[HumansAreBastards humanity as a whole is evil]]. As Nebula's head, Regal oversees the development of Dark Chips: battle chips that grant the Navis who use them great power at the expense of twisting their minds and converting them into mindless servants of evil. In the fourth game, he deliberately attracts the attention of the alien super program Duo with the evil of his dark chips, and puts the planet in danger of destruction [[EngineeredHeroism so he can play the hero and destroy Duo's incoming comet himself]] while sabotaging other, more reliable attempts at destroying it. When his deception is revealed, he tries to drop [[KidHero Lan Hikari]] to his death and attempts suicide to escape justice for his crimes. Surviving that, Regal returns in the fifth game and kidnaps Lan's father Yuichiro, who he [[ColdBloodedTorture brutally tortures]] in order to force him to give up the program known as Soul Net. Using Soul Net, Regal attempts to link the souls of Net Navis and humans alike to the powerful Nebula Grey program, with his endgame being to cause civilization to descend into hellish, violent, hate and rage-fueled anarchy. Vile and rotten to the core, [[EvenEvilHasStandards Regal disgusts even his own terrorist father Lord Wily]], who forcibly brainwashes him into becoming a better person due to the horrors he planned to inflict on humanity.

*** [[MorallyAmbiguousDoctorate Dr. Regal]] is the head of the evil organization Nebula and the BigBad of the Axess season. [[CardCarryingVillain A proud, villainous man]] selected by the godlike [=NetNavi=] Duo as a probe for human life, Regal sees himself as [[AGodAmI above humanity]] and schemes for the end of the world. Regal empowers the Darkloid [=NetNavis=] on their destructive campaigns through the Dark Chips, while slowly corrupting and driving all of them to insanity and degeneration through them and turning them against their leader [=ShadeMan=].EXE, whom he later brutally kills. Regal forces his fellow Duo-selected probe, Ms. Yuri, to [[IfYoureSoEvilEatThisKitten murder her own sister]] to prove her loyalty, and, in the climax of Axess, enshrouds the entire world in a dimensional area powered by the souls of tens of thousands of agonized [=NetNavis=], using his new power to annihilate entire populated cities across the globe while proclaiming himself the herald of [[KillAllHumans humanity's destruction]]. Returning as a digital entity in the following season's movie, Regal attempts to destroy the entire world yet again by using Wily's Spectrum program to digitize the planet while subjecting Lan's father to [[ColdBloodedTorture horrible torture]], and tries one last time to destroy the world in Stream while betraying Duo and proclaiming himself a god. Dr. Regal is a monstrous man utterly in love with his own evil who sees it as his right to annihilate millions for nothing more than the sake of his power and [[ItsAllAboutMe ego]].
*** ''Stream'': [[KnightTemplar Slur]] is an arrogant, zealous alien Navi and [[TheDragon the chief servant]] of the godlike program Duo. Tasked with distributing potentially dangerous Asteroid Navis across Earth to gauge if the planet is a potential threat that needs to be wiped out, Slur's [[FantasticRacism hatred for humans]] leads to her gaming her master's system in her favor. She goes out of her way to distribute Asteroid Navis to people guaranteed to abuse them, and nudges them into doing so while occasionally painfully deleting the Net Navis they already have. Slur's machinations cause a number of disasters to happen, such as the planet almost being devastated by a [[TheFamine famine]]; people being horrifically [[TakenForGranite turned to stone]]; a [[ColonyDrop meteor nearly flattening a city]]; and a number of near-mass murders on top of that. When the Cross Fusion team tries to stop her, Slur simply mass-distributes Asteroid Navis at a quicker rate and overwhelms them with chaos and mayhem around the globe in hopes of giving Duo the final push he needs to [[EarthShatteringKaboom destroy the planet]]. Despite claiming to be protecting the universe, Slur's motivations ultimately boil down to an obsessive, selfish desire to [[TheSocialDarwinist cull any and all life she deems inferior]].

Having already destroyed the recovering Planet AM, he sets out to do the same to Planet FM before being confronted by Mega Man, who he plans to keep in his collection as a mindless soldier that he can force to battle other EM beings as a [[ForTheEvulz form of entertainment]]. Upon his defeat, a gleefully defiant Sirius transfers the last of his power to Meteor G in an attempt to guarantee the destruction of the Earth out of little more than spite. Despite his short-lived status as an antagonist, Sirius's child-like selfishness and cruelty cement him as one of Mega Man's most twisted foes by far.

When Cygnus gets the Andromeda Key, Gemini Spark steals the key and reveals that they plan on using the key to [[TheStarscream overthrow the FM King Cepheus]].

[[AC:[[VideoGame/MegaManX X series]] (includes the [[Manga/MegaManX manga series]])]]

* [[MadScientist Dr. Albert W. Wily]], thought long dead, is, in truth, the GreaterScopeVillain of the entire series. With nothing resembling his more honorable traits from [[VideoGame/MegaManClassic the Classic series]], Dr. Wily created Zero as a means to finally create a robot strong enough to destroy Mega Man, and engineered the creation of [[TheVirus the Maverick Virus]], turning Reploids who were infected to violence and murder. Wily integrated himself into the virus itself and fostered countless amounts of death and destruction, most notably causing the fall of the once-noble Reploid [[Characters/MegaManXSigma Sigma]] to ambitious evil with thousands killed in his mission, and even nudging Sigma into trying to cause the fall of the colony of Eurasia to spread the virus further, which would consequentially kill off almost all mankind.

* ''[[VideoGame/MegaManZero Zero]]'' series: [[Characters/MegaManZeroWeil Dr. Weil]], known in Japan as [[NamesToRunAwayFromReallyFast Dr. Vile]], only appears in a few games, yet is notable for being one of the most evil beings in the entire franchise.

To this end, Weil corrupted Mother Elf by turning her into the Dark Elf, and triggered the Elf Wars. Weil used the Dark Elf and her children, the Baby Elves, to control Reploids and force them to fight each other in massive battles, which resulted in the deaths of 90% of all Reploids and 60% of all humans. Defeated, exiled and transferred into a mechanical body for his crimes, Weil eventually returned one hundred years later, consumed with a thirst for vengeance directed at all life for the perceived crimes against him. Weaseling his way into becoming the supreme ruler of Neo Arcadia, Weil turns it into a [[DystopiaJustifiesTheMeans dystopian hellhole]]. When he breaks his citizens to the point where they're desperate enough to risk escaping into the wastelands to form their own colony, Weil decides to obliterate their new home with a KillSat. When his Kill Sat is disabled, Weil attempts to [[ColonyDrop drop it upon the colony]], killing everyone in the region. Cruel, megalomaniacal and displaying an unprecedented level of sadism in the series, Weil reveled in the suffering of others and desired nothing less than to make human and reploid alike feel like their existences were living deaths.
