Complete Monster/Mega Man

"I AM THE DEVIL!"
 * Dr. Weil from Mega Man Zero has the dubious honor of being the biggest Complete Monster in the entire series. Not even Wily, Sigma, or even Regal (a fellow Complete Monster himself) can match him in sheer malevolence, insanity, and depravity.
 * Here's the lowdown in case you have to ask why he's here instead of any of those three. First, between the Maverick Wars and the Arcadia Wars,
 * One hundred years later, he drops down with Omega back online and has managed to construct a replica of X - unlike the Continuity Snarl of the first game, this one is clearly a copy - and wormed his way into supreme power that way, going so far as to have the Four Guardians dismissed. Then,
 * Even with Omega dead, Weil still rules Neo Arcadia, and his iron- and spike-fisted rule is so brutal that humans are risking going into the wastes of the outside world just to get away from him. Why does he do that? He thinks both humans and Reploids must pay for the crimes they committed against him, even if it's blatantly obvious that he is the one at fault! A caravan of such refugees, led by Neige, finds Area Zero - the site of the Eurasia colony crash - and begins setting that up as their "home away from home", only for Weil to send troops along to start to interfere with the region's recovery as a diversion while he gets Ragnarok up and running.
 * Though this last entry may go into Wild Mass Guessing territory, it is backed by some rather disturbing evidence.
 * At the end of the day though...it comes down to this; although he ultimately failed and they won... And he did all that because he thinks if anyone doesn't follow him, they deserve to die. Compare with Wily, who just wants to Take Over the World and stops there (Weil takes over the world...and make the people suffer even more!), Sigma who actually started out as a clean-cut, respected Hero, but fell victim to The Corruption, but still at first tried to do everything for the Reploid's welfare (Weil exhibits a very severe case of It's All About Me and cares NOTHING about humans and Reploids all the same). If that's not a reason by itself for a character to be a complete monster, I don't know what is.
 * Keep in mind that Weil existed for only two games,, and the rest of his atrocities are only revealed All There in the Manual. And yet, it's through those two games that he quickly gets through to the top of the Sorting Algorithm of Evil, beating Wily and Sigma so easily, all because his acts during the games are horrific enough; mere mention of All There in the Manual takes his monstrosity to the extremes. His actions and war were SO horrific that Neo Arcadia actually hid that part of history, going so far as to flood libraries and declaring anyone who found out a maverick, just so nobody could repeat "Weil's Sin". There's also the little fact that Capcom tried to humanize Wily and Sigma by uncancelling and (although scrapped) retooling their respective series to directly contrast Weil. That means the developers recognized (in other words, they knew) Weil is the most evil villain in the entire series. Sorting Algorithm of Evil, indeed.
 * Although the Rockman Zero manga was intended to be more jovial compared to the actual Zero games, Dr. Weil's characterization in that manga is just as monsterous. Like in Mega Man Zero 3, he was searching for the Dark Elf. At one point, he also emerges from underneath Lito's house to fight Zero, nearly killing Lito, and thus getting Zero extremely angered. He ultimately gets his Karmic Death when Zero smashes his chemical container, which was supposed to keep Weil alive.
 * It speaks volumes when his dragon (Omega), who has a MONUMENTAL (and by monumnetal, we mean most of humanity) body count worth of people who he has personally killed, isn't considered a Complete Monster. Then again, his crimes simply amount to being a mechanical Khorne Berserker on 'roids. As a matter of fact, the fandom loves Omega in a form of heel hate. Contrast with Weil, who the fans simply hate with the burning passion of a thousand suns.
 * On the subject of Omega, Zero was originally intended by Albert Wily as an Ax Crazy Complete Monster who killed with no remorse and no mercy before the then-Maverick Hunter Sigma knocked him unconscious. Then, during the Elf Wars, Weil transferred his data into the Mega Man Zero copy and, ironically, still turned the original Zero into THE monster Wily exactly wanted to create. In other words, Zero Omega still died a monster in a certain perspective.
 * Weil is even acknowledged as one in-universe: Basically, after Zero stops Pegasolta Eclair's attempts at dumping acid rain on Area Zero, Ciel remarks that she couldn't believe that Weil was even human to begin with.
 * We can sum Weil up in his own words:
 * We can sum Weil up in his own words:


 * Despite being a sequel series to the light-hearted Battle Network, Mega Man Star Force has three Complete Monsters.
 * Gemini from the first game In the anime,
 * Joker, from the third game,
 * Mr. King is even worse..
 * The fourth Mega Man X game gives us the Maverick Magma Dragoon, who ends up being the catalyst of the game's plot despite not getting a lot of screentime. Having been promised a glorious battle against X or Zero (Depends on who you play as) by Sigma, Dragoon infiltrated the military organization known as Repliforce and crashed the floating colony of Sky Lagoon into the city below which ended up killing thousands of innocent people. This also ends up getting Repliforce framed for his crime, which causes General to push for Reploid independence which is interpreted as a coup d'état by the Maverick Hunters and ends up getting him and his organization wiped out. Whenever confronted by X or Zero, Dragoon shows no regret for what he's done when X defeats him and views what he's done as being worth it. And while he does say "Sorry" to Zero if he ends up fighting him and losing, it's hard to tell just how sincere he really is given the fact that he still made the decision of his own free-will, unlike most Mavericks who are under the effects of some sort of virus or are pressured into doing evil deeds.
 * While Lighter and Softer than most other series, Mega Man Battle Network has its share of Complete Monsters:
 * Plant Man from the third game, who caused all kinds of mayhem in one of Electopia's main hospitals and was directly responsible for almost causing the death of an innocent child whom series protagonists Lan and Mega Man had befriended earlier. His callous disregard of human life is just as infuriating as the fact that he's trying to manipulate his operator, Well-Intentioned Extremist Anetta, into becoming just as cruel as he is.
 * Dr. Regal debuts in the fourth game as a Card-Carrying Villain with a somewhat nonsensical Xanatos Roulette...but it's in the fifth game that the true depths of his evils are revealed. His organization, Nebula, is devoted to converting the world to evil, causing wars, mayhem, and whatnot just to demonstrate his viewpoint - that Humans Are Bastards and, in fact, they should strive to be as cruel and horrible as possible. He also subjects Lan's father to an horrifying Cold-Blooded Torture and gleefully turns innocent NetNavis into servants of evil, slowly corrupting the whole Net. To be fair,, which would theoretically take him out of Complete Monster territory...but when you consider that yeah.
 * Want to know the reason for his ? It's because, disapproved of Regal's actions and took them away as punishment. Yes, that's right. Even , a person notorious for running a cyberterrorist organization as revenge on a scientific rival and nearly destroying the world as a result of using a prototype computer program to the Internet, disapproved of Dr. Regal's actions and made sure he paid for it dearly. If even someone like him disapproved of his actions, Regal sat quite nicely in that trope.
 * It is difficult to be both a Knight Templar and a Complete Monster, but anime-only character Slur, The Dragon to Big Bad Duo, delivers. Apart from being an absolutely broken Villain Sue, Slur is also fanatically devoted to exterminating all evil from the universe...where by "evil", she means everyone who doesn't agree with her master's extremely draconian concept of morality. In other words, Slur wants to kill all humans just because she doesn't like us. And unlike Duo, Slur has no sense of fair play - she deliberately "sabotages" the Humanity on Trial plot of Stream by giving Asteroid Navis to evil people, so that Duo will be convinced that Earth doesn't deserve to live. Vicious, sadistic, and with no redeeming qualities at all, Slur might very well be the vilest Battle Network villainess ever.
 * Which makes it VERY satisfying.
 * And yet, in spite of probably being closest on the pedestal of evil to Weil, she STILL doesn't hold a candle to him in evilness.
