Anime and manga creators have created a wide variety of villains, and some of them, like the ones on this page, are utterly horrific in their cruelty and depravity.
The following series/franchises have their own pages:
The creator of Basilisk really loves creating these. The Yagyu Ninja Scrolls brings us a full cast of complete monsters in Akinari Kato and his Seven Spears. Kato? Is a tyrannical daimyo who has women kidnapped and raped and will frequently kill or maim them in fits of rage. When he's done? He gives them to the Spears who rape and torture them to death. At the series' start, the Spears drag the captive men of the Hori clan to their wives, mothers, and daughters...and proceed to butcher the women horribly until they're stopped, leading to the series' Roaring Rampage of Revenge. Throughout the series, they commit many more atrocities. One can only cheer when series' resident hero and badassJubei Yagyu turns Akinari into a eunuch with a well aimed sword slash in a Crowning Moment of Awesome.
Ryoko Naruse from Shangri La experimented on children in a more horrifying way.
Akai in Kite is perhaps the most horrible character to ever appear in an anime. You think I'm exaggerating? Let's see...he killed Sawa's parents, raped her many times when she was a little girl, turned her into a killing machine, and to keep her at his service, gave her earrings filled with her parents' blood. Can you think of anything SICKER THAN THIS?
He also put other girls through similar treatment. And the best part? This guy is a cop who thinks he's making justice by sending the girls he rapes to kill other criminals (and we stress the word "other" because there is nothing even remotely lawful about what he does). The permanent smile on this guy's face shows that he has no remorse at all.
His partner in business (and raping), Kanie. He seems a bit retarded, and that makes him just a shadow of Akai, who is perfectly aware and proud of the atrocities he commits.
Keith White in Project ARMS. He is willingly the head of a research group that uses humans (usually children) as test subjects for painful, unethical, and often deadly experiments. When Alice asks if she and the children could just see the outside world for a second, he hits her. He then has all of the children shot, which leads to Alice being shot and merged with an alien lifeform, something which he shows absolutely no sorrow or regret over. When a colleague denounces the experiments as unethical, Keith laughs at him. Then, he creates multiple child clones of himself and implants them with nanotechnology, causing most to turn into monsters and die painfully. Even later, he shows up, taking over Keith Black's body, and is thrilled at the thought of Alice launching a nuclear missile and driving the Jabberwock to blow up America with anti-matter. When Keith Violet tries to talk him out of it, he tosses her off of a building. Top that all off with him kidnapping Katsumi possessed by Alice to get her to be taken over by the ARMS Bandersnatch and freeze the entire world. He kills Keith Blue, his son, with absolutely no remorse.
In a slightly different example, Yokoya from Liar Game definitely fits. He doesn't directly kill or hurt anyone, but while everyone else is in the Liar Game to win money to pay back their huge debts, Yokoya has plenty of money and only plays the game to manipulate people for his own amusement. He couln't care less whether or not people end up with millions of dollars in debt and will probably be traded as slaves to pay it back. He also used money, fear, and distrust to take control of his high school as a teenager. As a matter of fact, this quote says it all:
"...Some of his actions were despicable... Suicide when only half way to his goal! He could not be a true dicator... At the end of the day, he's still a failure... I will not become a failure like Hitler. Nothing will stop me from becoming a true dictator. In life... And, of course, in the Liar Game..."
...Although the 1941 Hitler was his role model...
You have a more direct example with Liar Game: Roots of A with a one-shot dealing with a treatment facility. The director is keeping the completely curable patients in "treatment" to leech government subsidies, i.e. make a massive profit and a source of free labor, while abusive guards torture and beat up these patients.See these pages for yourself.
The Big Bad of D. Gray-Man, the Millennium Earl, may at first seem too cheerful and cartoony to be scary. This impression, however, is veryquicklycorrected as we learn more about him. Being an Omnicidal Maniac is just the beginning: as an example, his favored tools of destruction, the akuma, are created in one of the most horrific ways imaginable - he finds people grieving at the loss of a loved one and offers to bring them back; if the grieving person accepts, the Earl then rips the soul of the departed from whatever afterlife there is and imprisons it in a black skeletal frame that kills the living person by forcing its way down their mouth and throat and uses their carcass to impersonate them and infiltrate human society to better commit atrocities, feeding the vicious cycle of grieving people unknowingly giving the Earl a way to create ever more akuma...
The Satan part becomes glaringly obvious when we finally see what's under his Nice Hat: horns.
Episode 7 of the new season of Darker than Black has a new Contractor character, Ilya, who is certainly an example of this. Prior to getting his powers, Ilya was a Serial Killer of women. As he himself notes, becoming a superpowered sociopath actually improved his behavior, as while before, he was Ax Crazy, now he can kill calmly and painlessly. While not stated outright, Ilya's Remuneration seems to be doodling pictures of murdered women, and he seems to do this of any female character he happens to see.
There are several others. The Gaiden introduces Claude. While Contractors are generally just amoral, Claude is actively a malicious sadist who loves using his powers to appear as someone's loved ones in order to torment them for a kick. The depths he'll sink are revealed when Claude murders a group of Contractors who were just trying to live peacefully. Oh yeah, and he tries to release a genocidal Eldritch Abomination because it's fun.
The manga, Shikkoku no Hana, presents two examples. First is the main villain Harvest, a Contractor whose powers involve the manipulation of matter. Harvest's idea of fun is to offer people Contractor powers themselves...what he doesn't mention is what it can do to them, and it also forces them to kill their best friends. Harvest even seems to take a very twisted sense of amusement in their suffering, regarding humans as utterly inferior on the evolutionary scales. The second example is Coach Daisuke Mioka, who shows a human being can out-evil any Contractor with his dickishness. He seduces his students - including his cousin, and then posts web porn of them. Bad? when one of them finds out, he manipulates said cousin to go speak to her...and hires a gang to go rape them both under the pretense of him 'saving the day'. Oh, and he gets a teacher to sleep with him by drugging her. Did we mention that he even tries to taser someone when they're deciding NOT to kill him? when Hei decides to kill a normal human in absolute cold blood, even if he's beaten to it, you know the guy is a nasty piece of work.
Harvest's excuse for what he does makes him worse. Amber once informed him he was inferior to Hei. Unable to accept this, Harvest is willing to practically burn the world down and infect countless people with the Black Dandelion to prove he's the superior being and that Amber was wrong about there being 'nothing within him'. The sheer hatefulness of his excuse and the revelation of how petty and selfish he is reinforces him as one of the worst DtB has to offer.
Szilard and Fermet of Baccano. The first will do anything to gain knowledge, and wants to give people immortality just so that he can absorb them and gain their knowledge and memories. The other, upon gaining regenerative immortality, killed a similarly immortal child repeatedly in incredibly painful ways for an unknown number of years. His excuse for doing this is that they need to learn the limits of their immortality and he's testing to see if there's a level of damage they can't recover from. That's his excuse, while the real reason is simply sadism.
While most villains are Laughably Evil, Faux Affably Evil, or simply cases of Generic Doomsday Villain who don't have much to their names, Lord Akudaikahn, the supposedBig Bad of Futari Wa Pretty Cure Splash*Star is a Complete Monster through and through - as is perhaps fitting of the somewhat Darker and Edgier tone of the season. At first, he doesn't seem very different from his predecessor, The Dark King of Futari wa Pretty Cure...but then, when he punishes Michiru and Kaoru's Heel Face Turn by paralysing them and burying their unmoving but still alive bodies in the depths of a huge lake, so that they will suffer eternally for their betrayal, the viewer sees that he's much worse than any previous villain. He's an Omnicidal Maniac who kills for pleasure, hates everything other than himself, and revels in destruction.
The realBig Bad, Gouhyan. By creating Akudaikahn, he's indirectly responsible for all of his crimes, and in the next-to-last episode, he actually manages to completely destroy the world. Why did he do that? Because he wanted to remain the only form of life in the universe. Luckily, the damage is completely reversed when the Pretty Cure, with the aid of the revived Michiru and Kaoru, kill him.
Yes! Pretty Cure 5 is Lighter and Softer than Splash Star...but the villain of its second season, the Director of the Nebulous Evil Organization Eternal, is another Complete Monster, though he still can't compare to Lord Akudaikahn and Gouhyan. His organization's whole point is to steal treasures and valuables from other worlds and keep everything of value for himself only. Okay, fine, that's bad, but not irredeemable. However, he also thinks that things which have no value must be destroyed - and he sees no value in humanity, friendship, love, and life itself - to the point that, come the end of the series, he has decided to make the Cure Rose Garden into a wasteland, thus killing every form of life in both worlds. And there's also the fact that he murdered his loyal Dragon Anacondy as soon as he had no more use for her, despite knowing that Anacondy had served him faithfully out of love. This guy is so bad that even NozomiYumehara, a sweet girl who tries to see good in anyone and has a story of redeeming villains such as Despariah and Dark Dream, was convinced that he was beyond redemption and needed to be put down.
The first one is Miboshi, a Creepy Child warrior of Seiryu who is older than he looks and who loves possessing other people's bodies and turning them against their friends, delighting at the suffering and confusion he causes. Unfortunately for him, because Evil Cannot Comprehend Good, he failed to consider that the possessed Chiriko would be capable of briefly fighting him off and willing to sacrifice his own life to stop him. Which the brave little warrior of Suzaku did, taking Miboshi with him.
Copy Rezo, the Big Bad of the first anime season and the third Light Novel. He destroys an city-state, wiping out all of its citizens and leaving Sylphiel the last of its citizens, all for the sake of provoking Lina into fighting him. His motivation? He is a staggering standout among those with the clone inferiority complex by hoping to make Lina cast the same spell that calls upon the highest deity in existence and could potentially destroy the world if miscast on him in the hopes that he survives. In other words, he will murder and destroy in order to surpass the original Rezo, who made a Heroic Sacrifice in order to allow the aformentioned spell to destroy the demon he was the host for. The fact that he will do those things in order to one-up a self-sacrifice via an apocalyptic spell means that Copy Rezo is an extreme omnicidal ''megalomaniac''.
Pick a non-comedic Hentai anime, manga, or game, any one of them. Chances are very good that the villain, if not some variety of tentacle monster, will be one of these, and if they just limit themselves to rape, count yourself lucky. Listing them all would at least double the page length; worse, they're often the protagonists.
Hellmaster fibrizzo of the second season would qualify as well. As the oldest of the Mazoku, Fibrizzo's ultimate goal is the destruction of alll reality. This is pretty standard for Mazoku, but the sheer joy which Fibrizzo conducts his manipulations,and even worse, when he tortures and kills his enemies lands him here. There are few other villains in slayers who take such unmitigated delight in causing suffering,especially when Fibrizzo seems to target loved ones to give as much pain as he can to his targets.
Medusa from Soul Eater. Complete Monster is really the only fitting description of her. Her list of evil-doings is long and continues to grow, so where do we begin? She's a witch who has used her own child, Crona, as a horrible science experiment, driving them to complete madness and not showing an ounce of love, much less regret. When Crona is finally shown, for the first time in their life, true kindness from Maka, they do a Heel Face Turn. At this time, Medusa is also trying to revive the Kishin using two witches, Eruka and Mizune, that she blackmailed into helping her—she can off them with a snap of her fingers. When she's defeated by Stein, she escapes in the form of a snake and takes over the body of a little girl. She uses this form to her advantage, knowing damn well the protagonists won't kill her if it means killing the child. She gets Crona in Shibusen to act as The Mole and drive Stein to (greater) madness. When her sister Arachne is revived, Medusa goes to Shibusen to ask for their aid in defeating her—she's given Shibusen's best students to help with the job. At this point, Crona's been captured and Medusa tells Maka it was Arachne who took her. When Maka defeats Arachne, Medusa takes over her sister's body and tells Maka she lied: she was the one who captured Crona. As of recent chapters, we see Medusa has driven Crona to insanity and broken him/her again to use against Shibusen and anyone else who stands in her way, all just as an experiment. She then gives Crona the first hug she/he ever got from her, driving her completely mad and killing her, all part of her sick plan.
To put it in further perspective: before Medusa appeared, Soul Eater was a funny, off-kilter Shounen whose main draw was watching the antics of its amusingly dysfunctional and mismatched protagonists. Afterwards, it started morphing into an almost-Cosmic Horror Story where people die or go insane by the truckload, and said protagonists aren't safe from being Driven to Madness. It still very much retains its weird sense of humour, though YMMV on how successful it is.
Maestro Delphine Eraclea from Last Exile, the leader of the Guild. A decadent, heartless aristocrat and a Manipulative Bitch who makes her younger brother Dio live in fear of her and ends up mind-raping him into insanity. If that wasn't enough, she tricks Luciola, Dio's only friend before Lavi and Klaus came along, by pretending to agree to let Dio go free... but Luciola ends up being dissolved by the ring she gives him. She also takes delight in pointing out how the delicious meals she eats needlessly waste the resources of the world...and goes as far as to say that the fact that people have died in order for her to eat such delicacies makes her meals all the sweeter. It can safely be said that Delphine is a beautiful, soullessbeast.
Gostello from Blue Comet SPT Layzner, a Gradosian officer who takes We Have ReservesUp to Eleven - his only real joy is killing people, the more defenseless the better, and his lust for blood is such that he often murders his own men just to get a kick out of it. Logic tells him that killing his own men might prove detrimental to him as well...but he's so Ax Crazy that he just doesn't care. To cement his Complete Monster status, in fact, he often refers to his victims as "prey" or "meat" and gets all tingly at the prospect of murdering people in the most gruesome of ways. Truly a monster, if there ever was one in such a dark Real Robot series. And his hilarious death of getting stepped on by a giant mech? WELL EARNED.
Louis L. Bridgette from Freezing. When he was only a kid, he whipped his half-sister, Satellizer, with a riding crop and presumably regularly molested her. He justified his actions by saying that since he was a noble and she wasn't, he could do whatever he wanted to her. Sure, his mom's a bitch, but there is no indication that she ever did anything to him and his sister is a genuinely kind person. Him sneaking into her bedroom at night resulted in Satellizer beating the crap out of anyone who touched her, so she could never form any normal relationships. What's more: now older, he's now obsessed with fucking Satellizer and abuses his Pandora, Holly Rose, horribly because she can't compete.
Gets even worse. He molests Satella again, gets Holly and Satella to fight, beats Kazuya...and becomes a fucking Karma Houdini afterwards by pulling the wool over everyone's eyes again. Many, many, MANY fans are considering dropping the manga after this arc since it sends a whole lot of bad messages...and Unfortunate Implications of how women are supposed to be around sickos like Louis.
The Novas, Abominations from another dimension who started a War against humanity just for lulz. They corrupt many Pandoras, forcing them to fight their comrades, and Body Horror seems to be their way of fun. It's almost like they rape the Pandoras to mind control them, too.
Legato Bluesummers, from Trigun. Legato's only purpose is to make Vash (the protagonist, The Messiah, and a Love Freak, master gunslinger for many years and yet has never killed a single person) suffer, which he does with great ease and relish.
Vicious of Cowboy Bebop. The reasonable response to your best friend seeing your girlfriend is not to sadistically force her to decide between her own death and having to kill her lover herself. Vicious has loyalty to nobody and thinks nothing of betraying former comrades to death or prison...he doesn't even register when men loyal to him give their lives as they're expendable to him. He also has no qualms about betraying anyone, whether he's usurping power from his leaders or cutting the throat of the foster father who saved his life.
Ogre (appropriately named). The only Big Bad in Rave Master without a Freudian Excuse. He wants to blow up a countrysmall continentFor the Evulz, with a stolen superweapon he finds appealing precisely because it managed to ruin lives before ever being used. Also, Slade, a seemingly minor character who is introduced and dies in the same flashback, yet, for the sake of a promotion, sends King over the slippery slope and sets his kid (who's all of six years old at the time) down the road to becoming the Ax Crazy maniac he is by the time the story begins.
Prince Braunschweig of Legend of Galactic Heroes certainly qualifies in a series full of Gray and Grey Morality. When protesting occurs on the colony world of Westerland, Braunschweig's response is to kill every single inhabitant in a nuclear strike...not even covering his continuance of the Goldenbaum dynasty's despicable policies.
The day karma came calling, Rudolf only cemented his status: when his only son, borne to him by his favorite mistress (and possible One True Love), was discovered to be a congenital idiot (simultaneously invalidating all his übermensch rhetoric and kicking him in the balls on a personal level), he ordered that any and all involved in the birth be executed - doctors, nurses, even the mother herself. Living to old age with no loved ones and Dying Alone hardly seems punishment enough, but like Real Life, life in Legend of the Galactic Heroes is seldom fair.
The Big Bad King Olban, unlike other Blamlings seen in the series (who have very sympathetic backgrounds and are Anti Villains who fight for their people), is just a cruel and power-hungry tyrant who cares for nothing but himself and openly states that the "peasants" only exist to be ruled, manipulated, and preyed upon by those in power. He's revealed in the series to be the mastermind behind the war between humanity and the Blamlings, as he murdered the previous king (Richter and Erika's father) and blamed the deed upon the humans to take power for himself, taking advantage of the Blamlings' desperate situation after losing their own home planet. That's how bad he is - he places his own ego and ambition above the survival of his own race.
As if to counterbalance this, the Earth side of the war gets an utter bastard as well: Chief General Sakimori Miwa, a frothing and rabid General Ripper who thinks the best way to settle disputes is to exterminate the opposing side. Ostensibly on the heroes' side, he actually tries to undermine Kazuya and his friends at every opportunity, even accusing them of treason, and cares nothing for the civilians caught in the crossfire, saying that it is foolish to pass up a tactical advantage out of respect for human life - he doesn't even care about the ones he's supposed to defend! Later in the series, he even goes so far as to personally execute a group of injured and defenceless Blamlings just out of hatred. Luckily, after this heinous act, Kazuya decides that enough is enough and gets a Crowning Moment of Awesome by administering a No-Holds-Barred Beatdown to the scumbag and leaving him half-dead, all while loudly calling him out on his bullshit. It's hard not to enjoy that particular scene.
It is telling that Super Robot Wars, more often than not, delivers them an even worse fate than the series did - Olban usually makes his last stand in a powerful robot so that the player can personally kill him; and Miwa often gets killed in a particularly gruesome and humiliating way (for instance, vaporized by a blast from Genesis in Alpha 3 or killed by the heroes while at the helm of a Gilga-Zamune as he's aiding SEELE in their genocidal plans in MX.)
Kano from Texhnolyze is a fairly good candidate. Being a product of generations of selective inbreeding and a batshit insane soplipsist who thinks that the entire world is inside his head, it's a bit unclear how far he can be considered responsible for his actions. But driving the city of Lux insane and flooding the streets with murderous cyborg soldiers for ideals that make so little sense that it could just as well be For the Evulz, along with the more personal atrocity of chopping off Ran's head and keeping it artificially alive on a statue to use her as an oracle, puts him deep into this category, if you choose to judge him by his deeds.
Keel Lorenz from Neon Genesis Evangelion counts, seeing as he not only wants to cause the full-scale of extinction of Humanity (like Gendo), but also orders in soldiers to personally murder every single member of NERV. Including Shinji, Asuka, and Rei, who are essentially children.
You get some of these in Franken Fran (and before anyone even considers it, Fran doesn't count; she's physically and psychologically unable to realize what she's doing may not be morally acceptable, and besides, she genuinely wants to help people even when her priorities are skewered). One of her employers, seeking eternal youth, had any doctor that couldn't completely fulfill her request decapitated (including Fran; Fran, however, could survive it) and their research stolen to increase her wealth, as well as mass-murdering clones of herself just to drink a juice made of their eggs. Then there's the "Very Lucky Man", a man born with an accelerated Healing Factor. He spent his entire life raping and killing because he knew there was no way to execute him for his crimes.
What, the list this long and still no reference to villains from Violinist of Hameln manga? Well, with Violinist of Hameln being a dramedy, most of the mazoku land in the Faux Affably Evil territory, as, even though they are mass-murdering literal monsters, devoid of any real redeeming qualities, their quirks and antics are regularly played for laughs. There are two exceptions, though:
Hell King Bass is a cold, emotionless Evil Overlord who is not only behind every atrocity that happens in the first 2/3 of the manga, but also personally takes the field to give 3/5ths of the main cast their tragic pasts. The worst thing he has done, though, is killing the greatest champion of humanity and one of his most passionate enemies, Lute, in an incredibly sadistic, spirit-shattering way, then turning Lute's body into a soulless puppet, forced to carry out his atrocities. And this was all done right before the eyes of Lute's mother and comrades. And once said body started breaking down, Bass intended to do the same to Lute's sister.
The Big Bad himself, Great Demon KingChestra, though, tops Bass by far. He is the only villain in the whole manga who is always presented with dead seriousness (even Bass, despite having no funny traits or sense of humor by himself, serves as the butt of a few jokes), invoking nothing but terror (in good guys) and awe (in his minions). To list his evil deeds is to list every scene where he appears and is not busy fighting the heroes, but the most salient example happens, once again, in the backstory. He not only seduced one of the kindest women in the world, Pandora, and pretended to be her loving husband for years, just so she will open the box for him, where his magical power and most of his mazoku minions were sealed, intending to kill and devour her once she outlived her usefulness, he also had children with her, just to make them live traumatic lives and eventually devoured them, after they suffer enough and develop strong enough magic to serve as a powerup, restoring his full abilities. The worst aspect of this? It is implied that, unlike the rest of the mazoku, almost all of whom are firmly stuck in Lack of Empathy and Evil Cannot Comprehend Good territory, Chestra actually felt love for Pandora...and still decided to proceed with the above-outlined plan.
Their evil is sometimes Played for Laughs, but still, Hayate's parents in Hayate the Combat Butler...sheesh, their ridiculously high Man Child tendences boot them right into here. They leave their son destitute after taking his salary and gambling it all away. And just to up the ante, they saddle a debt of over a hundred and fifty million yen on him while escaping themselves. The final insult? They send Yakuza to collect him for organs as a settlement for this debt. Hayate's 16...and they keep on kicking him even after leaving, withdrawing the fees for his school (which he was working to complete). And in the backstory, when Hayate tied to trust them one last time by handing them his girlfriend/mentor Athena's absolutely invaluable and very loved ring...they took it, promised to take care of it, and pawned it away without second thoughts, leaving Hayate to face a devastated Athena's wrath afterwards.
These two lazy bastards go waaayyyyy beyond Man Child. Hayate's father is unemployed, saying he's looking for "the perfect job", which apparently includes getting a fat paycheck for doing absolutely nothing. His mother has a gambling habit and couldn't care less where her gambling money comes from: Hayate's multiple part and full-time jobs, the YakuzaVery Nice People, wherever. And as far as we know, they left Hayate behind without a trace.
Dr. Tomohiko Katsuragi of Sakura Gari. Not only is he a disgusting pedophile and a Domestic Abuser, he drugs, rapes, and tortures Masataka (this includes whipping him, sticking a household object up his anus right after raping him, and holding his hand in boiling hot tea because of his jealousy over Masataka being the one Souma loves, when he loves Souma to an insane degree himself). Oh, and because Souma hated his stepmother Sakurako for raping him when he was younger, Katsuragi takes his words literally and forces a reluctant, young Souma to kill her. He literally took Souma's hand, which held a knife, and forcibly made him cut Sakurako's wrists, effectively killing her, while she was naked and passed out in the bathtub. And after the act, he also practically rapes Souma. Not only was Souma left traumatised by the deal, but this also contributed to Souma's "half-sister" Youya going from a simply adorable toddler into a scary Yandere and Creepy Child that calls himself "Sakurako", having walked into his mother's murder and gone mad from the horrifying sight. When Souma confronts Katsuragi on his rape and torture of Masataka, Katsuragi denies the accusation and tries to seduce Souma. He acts uninterested and mentions Masataka's name, so Katsuragi actually grabs Souma by the throat and tries to strangle him. Fortunately, though, Souma isn't fazed and deals him a huge Humiliation Conga. Which Asayo transforms into a Karmic Death.
Souma's stepmother, aka the real Sakurako, also lands herself a mention here, for the reasons already depicted.
Souma Saiki himself is a brutal deconstruction of the trope. He initially seems like a Complete Monster, at least to Masataka (who calls him out on it with a What the Hell, Hero?), when he tells him that he's responsible for all the deaths surrounding him, saying he effectively drove all his former lovers to suicide, shows no remorse for it, and says that he seduces and sleeps with anyone because he wants it. The truth is a lot dirtier and uglier. And that's before we get to the torture that drove him to be the way he, well, is. In reality, Souma is utterly fucked up due to his past and present, but still not completely monster-ized.
Bryan Hawk from Hajime No Ippo is as close to a Complete Monster as you can be in a story about boxing. Not only does he make resident jerkass Takamura look like an angel in comparison (and Takamura is NOT an angel), he's also batshit insane, animalistic, and only cares about fucking and hurting others. His backstory reveals that he only got into boxing because his trainer promised him he could hurt others as much as he'd liked and theoretically had a license to kill, as it would appear as an accident. And it just gets worse from there: he's actually racist against the Japanese and straightforwardly intends to kill Takamura in their match, while seemingly gettingsexual pleasureout of beating him. There are some truly nasty boxers in Hajime No Ippo, but at least they have pretty well-doneFreudian Excuses, and none of them comes even close to the disgusting depravity and assholish-ness of this character.
In the 1st movie, the Big Bad Kane is pure evil. It is stated that he has destroyed planets in the past. Toward the end, the hero's mother, Achika, says that "There can be no forgiveness for one such as you!" Pretty strong words for a story where a pirate is one of the main love interests for the protagonist and arguably the fans' favorite character. Then, Kane transforms into a black dragon...
Yuzuha from the 2nd movie. While in her backstory, she is seen as more sympathetic as she and young Yosho become friends, but then she's beaten up and banished away by the Juraian guards for being the spirit of a child-eating tree. Her utterly heartless treatment of her "daughter" Mayuka puts her into this category, epecially after she orders Mayuka to kill everyone. And when Sasami helps her break through her brainwashing, Yuzuha kills her. And she laughs about it, then whines about how she is supposed to be the wronged part in all the deal, even after all she's done against the rest of the cast.
A little known manga named Majin Tantei Nougami Neuro had Sicks, who takes this trope Up to Eleven. He's so evil that he is a completely different species genetically. He had done this so many times that one may wonder that if he's a Stealth Parody of this trope. Let's list what he has done.
During his introduction, he murders his son's love (albeit in a weird sense) in cold blood, then mocks him about it. Also, he had infiltrated the investigation team by making a mask of a person's live skin.
He then makes a mansion's worth of people butcher each other to appeal to the main character, Neuro. When that doesn't work, he simply blows up the mansion, killing the survivors out of boredom. This manages to disgust even NEURO, the demon who, throughout the whole series, barely ever broke his smiling and calm personality. He gives possibly his ONLY frown in the series.
To recruit the Second Finger, he presents him a cube, made of all the faces he ripped from everyone precious to him, including his family, friends, and co-workers.
For the Third Finger, he forced him to kill his father using his talent of medicine and some of the aftermath includes the victim's eyeballs popping out.
That guy was a monster from the moment he was born. He slashed all the others infants' necks in the nursery room in one night and slept peacefully the next morning! Then he killed his own mother and father at age 2 and 5, for god's sake.
Some of the titular Hell Girl's targets fall in this category, with their victims damning them to Hell after getting their life ruined by them. An example? Dr. Honjou from the first volume of the manga/early anime episodes, a vet who only studied medicine because, as he put it, "if some people are stupid enough to pay hundreds of thousands of yen to save their loved ones, why shouldn't I take advantage of them?" In fact, he only treats animals belonging to people who can pay a lot of money, prolonging their stay in his clinic only to squeeze more money out of their owners. Those pets whose owners can't pay as much are neglected and often left to die. When one of his clients, a Woobie of a teenager named Junko, loses her little dog (her only remaining friend) this way, she calls out the evil doctor in distress, to which Honjou calmly threatens to kill her and bribe his way free. The Dog Bites Back, though: Junko signs a deal with Ai and Honjou gets caught while he's trying to run a cat over with his car For the Evulz. Honjou is then taken away by demons, strapped to an operating table, vivisected while still alive and screaming, and sent to Hell to suffer forevermore. Couldn't have happened to a nicer person.
MeikoShimono is another. She's so greedy and selfish that she kills her parents to have their wealth, then kills her son (who was just a baby) so she won't have to share it. She also practically enslaves young Miki after her Corgis bit her so she can Work Off The Debt, abuses the child physically and emotionally, and finally kills the Corgis too by drowning them in her bath tub. Miki, who had also made a deal with Enma Ai and was wondering if it was a good idea, snaps and sends her to Hell despite Hajime Shibata's pleads to not condemn herself as well... Ai's assistants disguise themselves as the policemen who arrest Meiko for murder, trap her in their "police car", show her images of a gigantic baby perched on the car and monster Corgi pups surrounding her, and finally transform her into a dog woman as they send her to Hell itself.What a nasty piece of work.
The ace pitcher from episode 3. He's got a deal to go to the big leagues after he graduates, but the people offering the deal suggest that he shouldn't participate in the school baseball tournament. So what does he do? Get his entire team dropped out of the tournament. By beating one of the other players to death. And when he's confronted with what he did, he counters that he's a baseball prodigy, and if he went to prison for what he did, the entire baseball world would suffer, and that his victim should be grateful to be killed by the likes of him.
Ishihara is just as bad, if not worse than Sasaki. For one, he proposes murders even Sasaki is shocked about. But his worst crime is being responsible for Sakuragi's death, consider that he tried to kill himafterSakuragi erased the reason why Ishihara harassed him in the first place. That's right, Sakuragi gave Ishihara the letter Hagino wrote, which counts as evidence for the murder of Hagino by Ishihara and Sasaki, in exchange for leaving him and his friends alone forever. And what does Ishihara do? Stab him.
CaptainContinental of Legend Of The Blue Wolves. He tries to sexually subdue subordinates that take his fancy, and if they happen to refuse him, he whips them and beats them half to death unless they submit. And if even that doesn't work, he just rapes them and forces them to participate in various sexual activities with absolutely no remorse. In fact, he seems to get sexual pleasure (if his constant Slasher Smile is any indication) out of breaking, beating up, and raping people.
Cancer Deathmask in Saint Seiya. He looks Affably Evil when he appears first, but then he tosses Shiryu nonchalantly down a cascade while trying to convince Dohko to rejoin the Gold Saints via a Hannibal Lecture (which spectacularly fails). Later, we see more of his horrifying actions: when Shiryu and Seiya reach the Cancer Temple, they are utterly horrified as they notice that the temple's walls are full of screaming faces...representing the souls of all the people that Deathmask has murdered, whose souls he bound to the walls.And he cheerfully admits it when confronted. After Seiya manages to step forward and go to the next temple, he personallyand gleefully takes the mission of torturing and beating Shiryu to the extreme before even thinking of finishing him... Too bad that, when he was about to succeed, he decides to use his telepathy to toss Shiryu's sister Shunrei into a cascade, whichwasabsolutelythe last strawfor Shiryu.
The Devil Saint Guilty also belongs here. His entire screentime is used to:
C) Kill Ikki's Morality Pet Esmeralda (who, in the anime, was his own daughter!)
In fact, he deliberately invokes his monster credentials as he tries to break Ikki's spirit by pinning the blame of Esmeralda's death on Ikki, since had he not killed Guilty earlier, she would've survived.. It's hinted in the anime that he wasn't always a monster (Esmeralda says that the Cool Mask he wears drove him mad with its power), but we don't get to see it.
Kihara Gensei of To Aru Kagaku no Railgun, the Mad Scientist responsible for sending the children Professor Kiyama cared for into comas in his attempt to create a Level 6 Esper.
Incidentally, his son, Kihara Amata, was the one who trained Accelerator and made him who he was when we first saw him.
Complete Monster sums up the entire Kihara Family quite accurately.
Ren Sohma from Fruits Basket. Her start isn't that bad as she reaches for her Ill Boy future husband Akira and bonds with him, but things quickly go to Hell when she gets pregnant, is told that her baby is likely to be a girl, and fears that she'll "steal" Akira's attention. Her solution is throwing a tantrum in which she threatens to escape and get herself an abortion if her future girl isn't raised as a male, under the excuse of how a female leader would make the Sohma clan look bad. After Akira dies and leaves their daughter Akito without anyone to defend her, Ren constantly abuses and belittles her kid, telling her for several years straight that no one will love her, everyone will abandon her, and that she's only worthy of anything because she's the "God" of the Zodiac, and then, no one truly respects her. This causes Akito to grow into a terrifying mix of Yandere, Broken Bird, and Manipulative Bitch that would commit many terrible deeds towards the cursed Sohmas and the non-cursed ones, since she lives in absolute terror of being left alone and have outer people take the Sohmas away from her. And later in the story, not only does she have sex with Akito's sort-of boyfriend Shigure to spit even more on Akito's face, but she forces Akito to accept an outsider like Tohru as Shigure and Yuki's housekeeper as a bet, fully knowing that this would end up triggering Akito's rage and complexes at some point. Later, she manipulates her desperate niece Rin into getting Akira's last keepsake while promising to help her break the curse, and when that fails, and Rin is imprisoned and slowly tortured to almost death by Akito. She tries to kill Akito herself. Really, Akitois shown as a horrible person, but Ren is definitely to blame for lots of her bullshit, and it was for such a selfish reason too. Akito does get better and has a Heel Face Turn...thanks to Tohru, the girl who becomes a Spanner in Ren's cruel gambits. Immediately after Akira died and she learns that Akito was named the new head of the family, Ren immediately throws a fit and screams how "that thing" is just a "toy" and "Akira just used it to pass the time!" Also, she said this while little Akito was right there, recovering from watching her father die. Upon finding out what happened to Rin, Ren coolly tells her maid that she really was lying about knowing how to break the curse and says about Rin "worthless children really are just worthless".
The Mysterious Cloaked Guy (revealed to be Inasa) in Nabari No Ou. To start, he kills four-year-old Miharu - in a pretty gruesome way, no less. Later, he reveals that he's not only another immortal like Aizawa and Shijima, he's also actually Fuuma Kotarou...who's been tricking, playing with, and manipulating everyone from the start because he won't let anything stop him from possessing his "lovely Shinra-chan", though as he said, and Aizawa admits, he has been telling everyone all along that he wanted the Shinrabanshou...
Lord Trancy from episode 8 of season 2. He has a bunch of boys captured and made into his sex slaves right up until he dies of old age. He even gets rid of those that are "broken", calls the boys "dolls", and beats them. He's the reason why Jim Macken/Alois Trancy (the Sole Survivor among those poor boys) is...thewayheis.
Shirou Hisujikai of Ookami-san seems utterly delighted to recount his sins to Ryoshi, even with his victim standing right beside him to hear everything. He shows great zeal in revealing to Ryoshi how he attempted to rape Ryouko Ookami, at that time his innocent, trusting girlfriend, and then smear her reputation when she tried to tell others what he had done
Amon from Amon: Apocalypse of Devilman. He starts off as Akira Fudo'sSuperpowered Evil Side, granted to him by Satan himself, in the original Devilman manga and nothing is known of Amon's personality except that he was one of the greatest fighters in the demon ranks, and because of their fusion, Akira becomes extremely aggressive and violent towards his foes, much more so than necessary, such as ripping off the breasts of a female demon and eating them. Eventually, in What If? manga AMON' and OVA Amon: Apocalypse of Devilman, the horrid'' death of his girlfriend Miki breaks him and Amon fully manifests in the human world...While the manga tries to potray him as a Type VAnti-Hero, who is evil but still has standards, Amon from OVA is probably the most vile, sick, and twisted being to come out from anything related to Go Nagai. He murders other demons and humans just For the Evulz and has no problem with mindraping Akira with images of him eating Miki's dead body and smashing her head, but perhaps his crowning achievement of Complete Monster-dom happens when he finds an unconscious human girl in the rubble during his fight with other demons. He seems hesitant at what to do with her and picks her up. As soon as the girl wakes up, she looks up at Amon in horror and before she can shout, Amon starts EATING HER ALIVE! It's so shocking that the demons watching were absolutely horrified at what Amon just did.
The original manga also has Jinmen, turtle-demon who eats people alive and incorporates their faces into his shell - very much alive and concious. He has no problem taunting Akira with it. In fact, he ate somebody close to him and put that person's face above vital spot. Who he ate varies between versions - in the original manga, it was a ten years old girl named Sachiko, Akira's close friend; in the OVA series, it was Akira's mother; and in The Movie, it was an ex-bully who befriended Akira. The Movie even has special scenes of him attacking little kids he wanted to eat.
While Amon in AMON is nothing like his OVA counterpart, this series introduced a handful set of complete monsters in his place. Sll creatures send by God to fight demons are sadistic, manipulative, and have absolutely no redeeming qualities. Candy is solely responsible for convincing people there is no such thing as Devilmen, leading to them being prosecuteed and killed alongside countless humans believed to be demons, yet he is one of them himself and isn't to shy to admit to being a serial killer before his rise to power. Then there is God, who orchestrated the fate of the entire world since Satan has fallen, so he/she will lose the only person he/she loves as a punishment. And put the world on time loop so Satan has to suffer watching Akira die over and over again.
Most of Go Nagai's villains in general qualify as Complete Monsters, particularly in his more violent works. Violence Jack, by far Go Nagai's most violent work and set in the same universe as Devilman, has Complete Monsters in all of its villains, with the series' Big Bad, the Slum King, being the worst of them all.
While Diva from Blood+is a very evil bitch who raped and murdered Riku Miyagusuku just to impregnate herself, some people still find some sympathy for her due to her horrifying past. The real monster here is her caretaker, AmshelGoldsmith, since he and the original Joel's experiments turned Diva into the Ax CrazyThe OpheliaHive Queen that we meet. Amshel also has no qualms about killing anyone, including Diva's own chevaliers, if he feels they are getting in the way. In fact, it's revealed in the end that Amshel only cares about Diva as a specimen that satisfies his intellectual curiosity, and it's implied he raped her at some point, only to see if she could conceive a child with him.
Demerit points also, considering his actions towards his family, especially his younger brother, Holland, purposefully engineering horrendous civilian casualties to garner support for the war against the corallians (which had no reason to be, save for his world domination plans having no place for peaceful relations with Starfish Aliens), and the preparations he'd taken to take the entire physical and metaphysical universe with himby way of either Eureka or Anemone, should his bid for rulership of humanity and corallian genocide fail. All because of a Freudian Excuse that boils down to jealousy over what fate seemed to have chosen for him and Holland.
Just see another of his projects, the Ageha squad, and think what was probably required to make a bunch of 10-12-year-olds into dispassionate assassins/mecha pilots who view him as a father figure anyway.
If anything, he's even worse in The Movie, where he forces the Gekko kids into even worse experiments and abuses them. He's strongly hinted to be a pedophile too...
Severin from Princess Resurrection. This cowardlySmug Snake is the opponent against whom Hime (normally a calm, collected Lady of War) came the closest to losing her cool, and with good reason: before the series even began, Severin used his necromantic powers to raise an army of zombies and sent them to kill Hime, which caused her to lose all of her blood warriors - something which she still considers her greatest failure. Then, he does it again in Volume 5, infecting a whole city with a zombie plague and causing hundreds, if not thousands, of innocent victims - once again, just to kill Hime. Unlike Hime, who genuinely cares about her blood warriors despite her outwardly cold demeanor, Severin abuses and humiliates his servants every chance he gets. And just to top it off, he's the reason Hime hates being called by her actual name of Lilian: that's the name Severin gave to his cat, whom he tortured to death For the Evulz - which implies that he wanted to do the same to Hime as well. Luckily, he gets a very satisfying Karmic Death when Hime outgambits him and slits his throat with his own sword.
The eldest son from the Gowa family in Gasaraki, Kazukiyo. He goes so far as to assassinate a minister of justice in what looks like a tragic road accident, have soldiers injected with Psycho Serum and forced to pilot the series' mecha for 36 hours straight (something that his Mad Scientist brother Kiyotsugu actually refusesto do), provide assistance to a Well-Intentioned Extremist, allowing him to stage a coup, use his own little sister Misuzu in an experiment due to her powers as a kai (empath that can synch with the Humongous Mecha from the series) - something that, again, Kiyotsugu objects to - and commit patricide (and when his dad was trying to save Misuzu from him, nonetheless!) in order to achieve his goal.
His very ancient predecessor, Tsuna Watanabe, isn't any better, deliberately having the city of Kyoto set on fire, letting the firestorm of Gasaraki be summoned, and then torturing Yushiro by shooting him in the knees with arrows when he refuses to let the summoning continue.
Grace O'Connor andThe Omniscient Council of Vagueness in Macross Frontier, who use a fleet of millions of people as tools to take over the galaxy. It Gets Worse. The ultimate plan is to Mind Control a race of beings (the Vajra) in order to subjugate the other race of beings (Humans and Zentradi) and give them all the ultimatum of Mind Control implants or death, in effect enslaving the entire galaxy not just physically, but mentally as well. Yet despite all this, possibly their greatest crime is what they did to one little girl. They murdered her parents, tormented her on the streets where she was homeless and alone, and finally used her in an experiment that causes extreme pain, and assuming she didn't die like the previous eight subjects, she would still die in ten years. Her name was Sheryl Nome. She was seven years old. Grace becomes something of a tragic case of complete monster, as she comes to admit to herself that over the ten years she raised Sheryl, she came to care very deeply for her. She decides these feelings are probably going to get in the way of her mission and deletes them in what could be considered a very subtle but all the more damning crossing of the Moral Event Horizon.
Ajo from Key The Metal Idol. A former Japanese Imperial Army officer turned Corrupt Corporate Executive, he forcibly extracts the object-animating gel out of humans and has no care for human lives except as resources, eliminating anyone who stands in his way regardless of them being harmless civilians, children, or elderly and condemning others to a Fate Worse than Death just to feed his monomaniacal obsession with creating working Ridiculously Human Robots; he even did a Moral Event Horizon by doing a bad treatment on Miho, and especially his savage beating of her replacement.
No one expects a shoujo anime like Candy Candy to have a Complete Monster, but they do indeed have one: a Rich Bitch named Eliza Regan. Even though said Complete Monster doesn't commit murder or any heinous crime in nature, the way she treated a sweet girl like Candy, as well as other people, just for being Candy's friends, it's impossible to see her in another way. Despite Eliza's wealth and upbringing, this is NOT enough for her, and she makes Candy's life a living hell simply because it's fun for her. Not good enough for you? Well, there's also the fact that Candy is not her only victim; she screws with everyone else she can. Yep, because it's her ecstasy...
Eliza's twin brother, Neal, is almost as bad, especially when he gets a Villainous Crush on Candy herself...and instead of having a Heel Face Turn out of love, he attempts to pull a Scarpia Ultimatum on her. And yet he still doesn't come off as monstrously as Eliza does.
Dr. Aizawa manages to effectively take a formerly fluffy shounen-ai series like Sukisho and turn it into a tragic angst-fest of Nightmare Fuel proportions. He captured the two main characters when they were children and performed experiments on them that were traumatizing enough to cause them to develop split personalities. He then conducted an experiment that involved mind-controlling one of the children (Sora) into abandoning the other one (Sunao), causing Sunao to swear vengeance against his former friend. Also, despite Aizawa's defeat, he was never shown to have perished when his lab burnt down. For all we know, he could still be at large.
Sidou, the Sadist Teacher from High School Of The Dead. When we first meet him, we begin to wonder why Rei says that the students are better off leaving him to die. Then he proves it when a student he's guiding twists his ankle and begs Sidou for help. Sidou's response was to kick him in the face and say that the new world had no place for people that weak. Then he uses his position as a teacher to get himself elected leader of the surviving group. At another point, a student doesn't like the action going on in the "orgybus" and asks if he can just be dropped off at his house to see if his family is OK. Sidou and his group, who are at this point a cult, decide that the best way to grant his wish is to throw him out of the bus and let him get eaten. What's strange about Sidou is that his backstory doesn't seem to justify or wouldn't seem to create somebody as evil and downright insane as he is.
Tears To Tiara's High Priest Drwc. He convinces Riannon to become Arawn's sacrifice by threatening to chop off a little girl's fingers. There's also that whole "I want to summon a demon king to destroy the world so I can rule what's left" thing. Arawn's first Crowning Moment of Awesome is to shank the evil bastard; Riannon gets one when she kicks his undead ass.
In Black Bird, we have Kuzonoha Shuuhei. While all the male characters are a bunch ofmisogynist jerks, Shuuhei stands out among the whole bunch as the most cruel and depraved. Following a failed attempt to rape MisaoHarada, he severely wounds her to facilitate her abduction from Kyo's dojo. By his own admission, he has no qualms about injuring her as long as she is able to provide him with an heir that will consolidate his position as the head of his clan. Only a total bastard like this can make a Bastard Boyfriend like Kyo seem like a Knight in Shining Armor to Misao by comparison.
Many of the evil demon children in Gash Bell. In particular, Zophise horribly Mind Raped both humans and fellow mamono, both for practical reasons and For the Evulz. Riou and Zeon just barely dodged this status, only thanks to ultimately failing at their attempts to sadistically murder the main cast and blow up Japan just to get back at Kyomaro (their motivations were convincing, but in no way actually excuse their behavior). Finally, Clear Note was so thoroughly malevolent that Gash's ultimate spell, which destroyed only what was evil, erased everything that defined his person, leaving only his...soul, or whatever, to reincarnate as a different being.
Pandora Hearts: Isla Yura. He's messed up in the head, manipulates people for kicks, plans on re-enacting the Tragedy Of Sablier for further kicks, and, unlike other baddies, lacks a Freudian Excuse.
Ichinose from Phantom Memory Kurau is unique among the series' few villains in that he has no discernable Freudian Excuse. Even The Big Bad was a Well-Intentioned Extremist. Ichinose had no motive behind his attrocities apart from research or, more likely, personal enjoyment. Said attrocites involve experimenting on a young girl who was possessed by an Energy Being, to the point where she was physically and mentally exhausted. When he tried to force her to continue, she unleashed a surge of power that would have killed him if her father hadn't saved the sonofabitch. Years later, we see he's continuing his experiments, and after learning the girl is still alive and more powerful than before, he gives an expression that can best be described as arousal. It is soon revealed that the Big Bad has hired him to create an army of Super Soldiers, and we are given no reason why Ichinose agreed to this, so we can assume that he just wants to do horrible experiments. And they are horrible. Most of his subjects have died or lost their sense of self, and he shows no remorse. At one point, he suffers Laser-Guided Karma during one of his offscreen experiments, where he repeatedly says that he was "a fool". At first this seems like a form of redemption, right? Well, the very next time we see him, he used some device created by Kurau's Father to heal himself and reveals he only called himself a fool for not realising what went wrong with his experiments, and now he has successfully created his SuperSoldiers. He overshadows the Big Bad in terms of his sheer depravity and is the one character who is treated as irredeemably evil and possible insane. The worst part? There is nothing to indicate that he has died or faced any retribution for his sins.
Gosick gives us the charming gentleman Marquis Albert de Blois, a shining example of humanity who kidnaps a dancer in order to rape her and get her pregnant, steal her daughter from her, then lock said daughter away in a tower all her life to use her for his aims in World War II.
Naga's entire plan revolved murdering his own sister for power. If that weren't bad enough, along the way, he invades the human world and ruins the Bakugan one, causes the death or Fate Worse than Death of a multitude of Bakugan, and brainwashes two innocent humans into being his Dragons, all without any remorse.
King Zenoheld's original plan was to enslave the Bakugan to use them as entertainment against their will, passing them off as inanimate playthings. When they got free and were revealed to be sentient beings (a fact that horrified a large number of his followers), his response was to bring in the Bakugan Extermination System to perform a genocide on them simply because he lost. When that's stopped, he has a Villainous Breakdown and goes Omnicidal Maniac, trying to destroy the entire universe, all because the Bakugan got their freedom from him. He also treated his son like a disposable soldier, which came back to bite him in the end.
Emperor Barodius is a power-obcessed tyrant who declared war on a peaceful planet for no reason other to gain more power than he already had, showing a willingness to wipe the entire planet off the face of the universe to get what he wants. He's also a firm believer in You Have Failed Me and You Have Outlived Your Usefulness. If he doesn't kill you for either of those things, he brainwashes you into his loyal puppet. He also kidnapped a large number of kids from Bakugan Interspace to brainwash into his loyal soldiers. Once again, he did all of this for power when he already rules his own plant! If he wasn't evil enough as it was, the fact that Code Eve saw it fit to not vaporize him, but instead imprison him in an alternate universe for eternity, sealed inside armorcreated from his own evil and stuck to his throne. Then he comes back as Mag Mel and gets a lot worse.
Mag Mel is possibly the worst of them all. He spent the series as a Sealed Evil in a Can in three different ways at once, showing that whoever put him there really wanted to make sure he never got out. What did he do to deserve this? He commited genocide. His current goal? Destroy the Earth. Venoheld went through a Villainous Breakdown from one too many failures to become an Omnicidal Maniac, Mag Mel already was one to begin with. What makes him even worse is his use of his Psychic Link with Dan and Drago. His primary use isn't that bad, siphoning off energy to free himself. It's his secondary use of it that makes him outright horrifying. He uses it to Mind Rape them with terrible visions of the destruction he intends to cause and to mock and taunt them. Does he need to do this for his plan to work? No, sending his henchman to battle them is enough to do that. Mag Mel is doing it just because he likes it! He performs Mind Rape on a boy and his best friend for fun. Turns out, he's actually Barodius. You'd think being locked up in armor that's Made of Evil and imprisoned for eternity in another dimension for his genocidal crusade against Neathia would've taught him a lesson, wouldn't you?
And then there's killing Mistress Sellon even though she'd completed her asignment perfectly and hadn't failed him. He slowly distingrates her into nothing as she pleads for him to let her live to see his plan go through. He kills her and absorbs her energy, saying that her will to live was impressive but he'd much rather use her energy to fuel himself. Even though he was notorious for doing this as Barodius, the sheer sadistic pleasure he takes in it as Mag Mel shows that if there was any good in Barodius, it's died since he became Mag Mel.
Liang Qi from Canaan is one really, really psycho Dark Action Girl. What puts her here is neither her abuse of Yunyun or Cummings nor her horrible No-Holds-Barred Beatdown on Maria, though both episodes are effing bad...but tricking Hakko into killing her beloved Santana with her lethal voice, and then mocking her over the monitor.
The Elementary School Principal, Kuonji, from Gakuen Alice. Kidnapping, extortion, blackmail, child abuse, child slavery, etc. He's not even remotely a good person.
To elaborate, at first, he turned Luna against Yuka and made them enemies. Then, after Yuka's stealng alice was discovered, he forced her to go on missions and steal the alices of dying/dead people. He was also responsible for Izumi Yukihira's death, practically brainwashed Rei, AKA Persona, implied to be resposible for Kaoru's death, burned Natsume's hometown by making Aoi's alice go out of control and held her hostage to ensure Natsume's loyalty, caused Yuka's death, and severely injured Narumi. He's currently holding Mikan hostage, preventing her from using her alice to heal Nobara. Oh, and his clone is the boss of the Z organization, which kidnapped Natsume and nearly killed Hotaru.
For a kid-oriented show, GaoGaiGar gives us seven of the 31 Primevals, the Arm Primeval, the Nail Primeval, the Ear Primeval, Eye Primeval, Intestine Primeval, Rib Primeval, and Liver Primeval. They brutally conquered Soldat J's world, killing all its inhabitants. To beat Kaido, the Intestine Primeval even took over his adopted mother's body so she could kill him in the worst way. Unlike the other Primevals and the Zonders, they're shown in an absolutely evil light no matter what their programming.
And then, in FINAL, we have the 11 Soul Masters, which are a bunch of Omicidal Maniacs trying to destroy the entire universe by sucking up all the Dark Matter to revive the three worlds. The only one who seems to be...decent is Volfogg's opponent, Polturn. Palparepa, Pillnus, False Able, and False Cain are the worst of the group, psychologically torturing the Braves and GGG. False Able even turned Kaido into a living battery for Pia Decem to prevent Soldat and Renais from attacking. Pillnus psychologically tortured, physically tortured, AND is implied to have rapedAction Girl Renais. And Palparepa takes special pleasure in beating Guy down every time he can and making him Brainwashed and Crazy to attack his friends!
The rulers of the Three Clans in Dance in the Vampire Bund, Lords Rozenmann, Li, and Ivanovic. Their backstory involves them betraying their rulers and killing their queen in a highly unpleasant manner, sparing her young daughter solely so she could bear a child to one of them in the future. They subject Mina to a highly humiliating and degrading 'chastity test' every decade to lord their power over her and play a game where they sent assassins after her beloved bodyguard to determine who gets her hand. This is the tip of the iceberg. Ivanovic was Rasputin, who drove the Russian royals to ruin. Mina barely managed to rescue Anastasia from him before he raped her. His obsession due solely to her resemblance to Mina. It's more than implied Ivanovic is a rapist with a taste for young girls. And he invades the bund and has the innocent fangless executed. Rozenmann is the most affable of the lot, but he's easily the worst, masterminding nearly every unfortunate event in the series.
Lord Wolfram, the Villain Protagonist and sadistic guardian of the titular fortress in Wolfsmund. Wolfram makes psychological and physical torture a fun pastime and nobody is able to sneak past him. One of the first things we're told about Wolfram is his execution of a man who tried to sneak through his fortress, along with the man's entire family. He proceeds to string along people trying to flee the Hapsburg dynasty, letting them have as much hope as he wants before crushing it and destroying them.
Kogan Iwamoto, the head of the Kogan-ryuu Dojo in Shigurui, particularly for his treatment towards women. So great is his cruelty in and out of combat that even the psychotics and pedophiles among his students are taken aback. Indeed, in a series full of depravity and madness, he consistently stands on his own mountain of heartlessness. Two key examples:
He cares nothing for his daughter, Mie. He wanted a son instead and only sees her as a vessel for carrying the dojo's heir. Thus, he's willing to watch her get raped by one of his students to make sure she got pregnant, slashed through a student's face for suggesting she should have a husband that respects her, and scoffed at her mother committing suicide when Mie finds her body. When the man first picked as Kogan's successor, Irako, is cast out, she spends years starving herself, eventually reducing herself to a semi-sane bag of bones. He only shows concern once he realizes she won't be able to give birth in such a state. And he almost rapes her himself.
His concubine, Iku, is seen as cursed by the locals, as every man she gets involved with dies in one way or another. Thus, she is grateful to Kogan because he was kind to her despite that...until one of his top students, Irako, tells her that Kogan killed her first husband just to show off a sword technique. She and Irako become lovers behind Kogan's back; when he finds out, he slices off both her nipples, mutilates one of her breasts by burning it, and then blackmails her into burning a hole through Irako's penis. Oh, and this is AFTER Irako is tricked into getting beaten to a pulp by his fellow students, but BEFORE Kogan personally blinds him by slicing his eyes open.
For a rather optimistic show, Tiger & Bunny has suprising share of these.
There are the criminals from episode 6, proudly admitting they killed the kid they kidnapped for being noisy, and one of them seemd to enjoy his previous criminal profession, which was kidnapping entire families for ransom, and then killing them once he got what he wanted. They are killed by Lunatic right after that.
Another one is Lady Killer, who sexually assaults and kills women for fun and uses a whip to make it more painful, who is also killed by Lunatic.
Then there is the Big Bad, Albert Maverick, who is a real piece of work - he employed a mysterious criminal organization with advanced technology in return for them providing supervillains to make Hero TV more marketable. When Barnaby's parents found out, he killed Barnaby Sr. and Emily and brainwashed Barnaby to forget the killer's face. He then raised him to be the best of all heroes, to improve the ratings, and when Barnaby found out, he just mindwhipped him again, with the implication that it might have happened before, in a scene looking very much like a date-rape. With Kotetsu on his trial, he has no problem staging a terrorist attack to keep him occupied, brainwashing all his friends to forget his secret identity, killing Barnaby's friend Samantha and Kotetsu's only lead, and framing him for this.
There is also Dr. Rotwang, NEXT-hater who kidnaps all heroes, plants bombs on their necks, and taunts them with a Sadistic Choice - he will blow them up once his android defeats Tiger and Barnaby, but one of them can survive if he or she sacrifices everybody else by detonating their bombs. What's worse is that he is lying - even if one of them pushes the button, everybody will die. And then he does everything to make them turn against each other and is disturbingly excited when one of them almost succumbs to tempation.
Those last two had a Villain Team Up and managed to out-monster each other - Maverick was clearly disgusted with Rotwang's hate for NEXT. He also has no problem with killing Rotwang once he did his job, right after revealing that he is NEXT himself, just to add insult to the injury.
Dr. Kenmi from Sacred Seven has become one in recent episodes. From his torturous experiments on people with Darkstone powers to the fact that he killed Rinoa's mother and father to force her sister Aoi to activate her powers? Yeah...
Now he wants to pull out Ruri's heart to get her Darkstone Core...after ruining her financially by making it seem like she was not paying her taxes and everything to destroy the Foundation.
He was also responsible for the "random" Darkstone attacks early in the series, which were all attempts to force Arma to go berserk and thus endangered countless innocent lives.
Claymore finally has a Complete Monster in the form of a former Number 1 ( previously a number 2), Roxanne. Despite her good looks, she's an absolute sadist, especially in regard to her former comrade Cassandra. Her Moral Event Horizon, as revealed in 119, is causing the death of Cassandra's only friend, then mocking her to make her go berserk on the other Warriors. She then impaled Cassandra's head with the sharp pommel of her sword. It gets worse, though. The Awakened Being killed Cassandra's friend very, very slowly, and it's implied it raped her. Roxanne cheerily says she looked like she was enjoying herself, so interfering wouldn't be right.
Manami from Life is about as much a Complete Monster as a teenage girl in a normal high school setting can be. She's tried to get the protagonist and her best friend murdered, raped, and possibly made into a Snuff Film. She's tries her best to make Ayumu's life a living hell, forces all the other girls in her class to either bully certain individuals or face the same sort of harsh bullying, and says she aims to kill her bullying victims (be it by driving them to committing suicide or other measures).
In Mawaru-Penguindrum, up until the first half, those opposing the Takakuras were revealed to have at least a sad or sympathetic background, I.E, Masako chases after Kanba relentlessly, but she also wants to save her brother Mario; Sanetoshi is a Manipulative Bastard, but he lost his "special person" and still longs to find her again. However, in episode 15, we see that the latest "antagonist", Yuri Tokikago, is a thoroughly broken person, and a Complete Monster was to blame. Said monster is her own father, a famous Mad Artist who carved his daughter's body with a chisel to make her "look beautiful" and be worthy of his love, while telling her that no one would ever love her because of how "ugly" she was. This happens in a flashback and that, in these scenes, Yuri is no older than 8 years old. And it's really not helped by the huge sexual abuse vibes and the implication that Mr. Tokikago either killed or drove away Yuri's Missing Mom because she lost her "perfect beauty" after giving birth to Yuri. No wonder said person developed some of the biggest issuesin a series that's already very complicated.
Fate/zero has Caster and his master, Ryuunosuke. Before he even joins the Grail War, Ryuunosuke is a sadistic serial killer who murders children and women especially. Caster, AKA Gilles de Rais (know anything about him and you already know why he qualifies), and him get along because of their love and appreciation for one another's talent for slaughter. Caster shows his colors when he frees a child Ryuunosuke had captive...then has him horribly killed just as the poor kid begins to hope, because for this sick bastard, it's just more fun that way.
It also has Zouken Matou. After reading the visual novel, it's hard to imagine how he could become more hateable, and yet with his actions in Zero, not only raping and torturing a four-year old child, but even gloating about it to Kariya (who had made a deal with Zouken to fight on his behalf in return for Sakura's freedom if he won).
Herbert Muller from Phi Brain Kami No Puzzle - in his initial apperance, he tricked a kindergarten teacher to lead a bunch of little children into semmingly innocent puzzles, which he remade to be deadly, just to hope this level of fear will consume Kaito and his friends and get them killed. Yes, he has absolutely no problem with sacrificing little children to get his opponents. He is also said to be the "dark face" of P.O.G., implying that all it's members we seen until this point were the better side of the organization. One of them wanted to destroy a city if his puzzle wasn't solved. And Muller is apparently worse.
GHQ's superior in Guilty Crown after he becomes President. He creates a giant barricade and shrinks it daily and orders his soldiers to kill everybody who was unlucky enough to be near the red line. Daryl of all people had a problem with that.
Silcardo Jenazad from Kenichi: The Mightiest Disciple. Let's list his offences in chronological order: inciting civil war in his own country 20 years ago (which he's still actively maintaining) simply because he was a Blood Knight who couldn't stand lasting peace; causing his past students to fight and kill each other for his own research purposes; causing an avalanche to kill his own modern-day YOMI student (who, granted, wasn't a very nice guy himself to begin with); tricking fellow YAMI member Akira Hongo into almost killing the titular protagonist; kidnapping and brainwashing Furinji Miu into becoming his newest cold-blooded disciple; and just recently, he's trying to kill his country's deposed princess (the sister of the aforementioned slain YOMI disciple) because she's all for restoring peace to the nation.
And most recently, during said ongoing civil war, Jenazad is informed by one of his servants that the men fighting on his side—men who joined him because they were devoted to his cause—will die in large numbers if they persist in the current segment of the conflict. Jenazad's response: "So?"
And he doesn't even stop there: adding to one of the above-mentioned points, he later supervises the Brainwashed and Crazy Miu's battle against Kenichi, with the expressed purpose of getting her to kill Kenichi so that her mental state will be completely subject to Jenazad's manipulation, and the brainwashing process to make her go fully Face Heel Turn will be complete.
HarunaNeikawa from Durarara!!. Let's see, she tries to murder a girl whom she perceives as a threat to her relationship with a stalker teacher who broke up with her a year before and whom the other girl is utterly terrified of. Monsterous? Definitely, but that's not the worst thing she had planned. The worst thing is when she hears a knock at Anri's door and assumes it's one of her friends (it was actually the stalker teacher, probably planning to rape Anri), and tells Anri that she's going to tie up her friend(s) and kill them right in front of her and force her to watch. For the record, this would do absolutely nothing to benefit Haruna herself, and it's pretty clear that the only reason she wanted to do that is to make Anri suffer more. Oh, and before anyone says that this is Saika's doing; usually, if you're capable of love, Saika will just turn you into a mindless zombie. But Haruna does not, and it's made very clear that she is working of her own freewill, especially when it's revealed that Anri, Saika's true master, can't control her.
That stalker teacher who broke up with her? He broke up with her because SHE was stalking HIM.
Pluto has Adolf's brother, who was a serial killer of robot children. Two things to put in perspective how bad he was. First, when Adolf wants to avenge him, he gets What the Hell, Hero? speech from his own wife, not because he wants revenge, but because he wants it for the sake of such a bastard. Second, Fantastic Racism in this world is so big that there exists Anti-Robot cults that is a KKK, and even they think this guy was a despicable scum.
RikuOusei from Linebarrels of Iron. Most other members of the Katou Organization have at least some redeeming qualities (with Jack Smith being a full-fledged Type IVAnti-Villain), and Big Bad Hisataka Kato himself is an Affably EvilWell-Intentioned Extremist. Ousei, on the other hand, is a slimy little prick who delights in blowing people up from orbit with a Kill Sat just to make a point about his twisted concept of imagination (a bastardized take on his boss' own vision), and he is ready and willing to kill off a couple of innocent bystanders (a young man and his girlfriend who knew nothing of what was going on) just to taunt Koichi and drive him into a rage. And after doing that, he was going to repeat the atrocity, this time targetting Koichi's Unlucky Childhood Friend Risako. A truly despicable snot. Therefore, it makes it a Crowning Moment of Awesome for Koichi and Satoru when they destroy him and his Kill Sat when he's one second away from killing more people.
Yukino from Yakitate!! Japan may not have quite as much killing and mayhem under her belt as some of the other people on the page, but the manga's pretty clear that it's only because she doesn't have the opportunity. She only takes joy in the suffering of others, as exhibited in the chapter where she has Kawachi's bread dough sabotaged, forcing him to try to get it to rise by kneading it so long that he passed out...she was working so hard to restrain so much laughter that she almost soiled herself. Which seems fairly mild compared to the sheer paroxysms of glee she worked herself into by torturing her illegitimate little sister with the desecration of said sister's mother's remains. She's lied, cheated, and killed all so that she can have 100% of her father's company instead of just 90%.
Andrea Cavalcanti, aka Bendetto, of Gankutsuou. He briefly seems to be a highly cultured fop and a decent guy and continues to put on that persona, but he's really a total psychopath who attempts to rape his half-sister Eugenie, seduces his mother, stabs his father, and laughs afterwards and attacks Haydee and looks like he was trying to rape her as well.
Me-Mania is an Ax CrazyGonk bastard that is a Loony Fan for Mima in Perfect Blue. His ugly appearance helps to show how ugly he is on the inside. He murders people connected to Mima after she quits her singing job and attempts to rape and kill her, all the while throughly enjoying himself.
Plus, there's the fact that it was heavily implied that she was going to rape Setsuna when she hit Setsuna with a Clothing Damage spell, followed by pinning her to the ground and slowly and deliberately cutting off Setsuna's Sarashi bra.
Redda of Mon Colle Knights rarely picks fights with characters that are either weaker or stronger than he is, but that's because he doesn't need to. Instead, he prefers to stick with his mastery of manipulation, which he takes pleasure in using on others, especially to the point of driving them to suicide, and loves subjecting things to disturbing splooshy transformations. And that's not all: he even takes Rockna hostage and sticks her inside Dread Dragon's neck and commands it to create a wormhole that sucks all of Mondo's monster friends inside it, leaving Mondo with a Heroic BSOD, after which it takes him a bit to get better. And thanks to Redda himself, Rockna was ACTUALLY this close to being slaughtered in a truly terrifying way. Nightmare Fuel much?
Phine, the Big Bad of Senki Zesshou Symphogear, had took over body of her cheerful and friendly descedant, slowly destroying her mind, manipulated the young girl into beliving that she can create the peaceful world she dreams of only by forcing people to stop fighting, turning her into her Dragon, which she abused and tortured - her punishment for a failure was being electroduced - with implied sexual abuse if not outright rape, forced her to use the Artifact of Doom she wanted to test, tried to kill her once she didin't needed her anymore, secretly experimented on the main character, temporary turning her into a rampaging monster that cannot tell the friend from foe, and when offered a chance for redemption, she decided to sacrifice herself to do a Colony Drop. And her motives are extremely convoluded - in the span of few minutes, she goes from wanting to lift God's curse from humanity through creating cultural and climatic disaster that will throw humanity into chaos, forcing them to embrace her as it's ruler, to being Yandere for God - so it's impossible to feel any sympathy for her.
Kamishiro from Towa No Quon - ruthless commander in charge of hunting Attractors in Japan (who really is one of them and drains powers of captured Attractors) - proves how bad he is in the final two episodes - he tortures a man for information, sets a mook on fire just to check out his power boost, convinces a group of children under Quon's care and one of his friends to leave with him only to imprison them, probably with an intent of draining them later, and almost kills kidnaped telepath and Quon to reawaken the most powerful Attractor in the world, only to drain him and use his powers to wreck chaos and randomly mutate people for kicks, and is prettysmug.
While Magi - Labyrinth of Magic has several unnecessarily cruel villains, most of them have some minor redeeming qualities or Freudian Excuse, with one big exception: Jamil, the ruler of Qishan. Smug Snake, Dirty Coward, you name it. He also gets quite a kick out of abusing slaves and underlings, and flashbacks show him doing this to children — all with the cheerful, smug grin of a true sadist. Morgianna is so loyal and obedient to him that, at first, it appears to be a case of Happiness in Slavery, until her point of view shows that his physical and emotional abuse has simply broken her into unconditional obedience. He's also the only villain that the cheerful, idealistic Aladdin makes no attempt to redeem or befriend.
Death Note: Kyosuke Higuchi from the Yotsuba group is certainly a Complete Monster. To be precise, Higuchi abused his employees before getting the notebook. Then, when he did, he killed people with slim to no motive whatsoever. He also tried forcingIdol Singer Misa (who dislikes him not just because she loves Light, but for being a Dirty Old Man) to marry him so that he could get money from insurance for when she would die by his hand..This caused Rem to prefer Light over this slimeball and makes the Humiliation Conga he goes through, ending with his arrest by the task force and death via Light's watch slip, even more satisfying.
Akio from Revolutionary Girl Utena fits despite not killing people on screen. However, he is responsible for his sister's century long torture as he manipulated each and every Rose Prince that came around. His manipulations are so petty, so mean-spirited, and so cold, it's hard to believe that he and Dios are the same person. In fact, it's more likely Dios separated himself from Akio ala Kami and Piccolo Daimoh to keep himself a hero. What he had done to Utena and Anthy is absolutely unforgivable.
Deep Blue of Tokyo Mew Mew. Sure, he's another alter-ego of Aoyama-kun, very much like the Blue Knight, and he looks similar to him, too. But admit it, unlike both of them, he's an absolutely terrible person. He's cold and extremely cruel and is willing to kill anyone who gets in his way with no remorse whatsoever, and he doesn't share their feelings towards Ichigo, nor does he hesitate to hurt her or any of the other Mew Mews, despite Ichigo's refusal to fight against him. He also kills Quiche for getting in his way as a sacrifice for protection of Ichigo, and unleashes beams that threaten to murder the other Mew Mews until Pie sacrifices himself to save them; if it weren't for this Heroic Sacrifice courtesy of Pie himself, Ichigo's teammates would've been slaughtered in a truly horrible way. It all eventually leads up to Deep Blue's Villainous Breakdown as Aoyama-kun fights back against him from within him and eventually forces Ichigo to finish him off and kill both of them in order to free Aoyama, which is a truly satisfying end for this alien menace himself.
Yoshiyuki Tomino gives us another despicable villain in Zambot 3, in the form of Killer The Butcher, The Dragon to Big BadGaizock. During the series' run, this guy commits any sort of horrible action, the mildest of which is mass murder of innocent civilians with the excuse that Humans Are Bastards. If, by the end of the series, you still don't think this guy deserves a quick, brutal death, just wait until he implants mini-bombs inside unknowing human prisoners, just to release them, let them go back to their families...and only then blow them up. Alive. Even children. And all the while, he admires his work, is proud of the bloodshed, and even jokes about the horrible deaths of his victims, treating his killing sprees as a funny game.
Friend of 20th Century Boys. The first Friend is responsible for 150,000 deaths by spreading a virus over the globe, a virus of his own creation after reading the Book of Prophecy that Kenji (one of the heroes) created, then framing Kenji's faction and calling them terrorists. He becomes the 'savior of the world' and sends people who just WRITE MANGA to high security prisons. While the Seconds Friend's actions were even more horrible than the ones of the First, at least the Second Friend is revealed to have had a truly shitty childhood to the point of contemplating suicide - it doesn't manage to serve as a Freudian Excuse. However, the First Friend (Fukubei) was really just an egocentric asshole sneering at pretty much every other person while simultaneously being a massive Attention Whore, who decides to do what he does out of some really petty grudge against Kenji.
Akechi Mitsuhide in the anime adaptation of Sengoku Basara. He gleefully leaps over the Moral Event Horizon in episode 5. It's not when he goads Nagamasa into fighting Masamune. It's not even when he diverts a squad of riflemen from supporting Ieyasu (screwing over Ieyasu too, in the process) to fire on Masamune, with Nagamasa right in the middle. No, it's when he brings Nagamasa's wife, Oichi, to the site (on the pretense of letting her warn Nagamasa), and then picks the very moment she tries to warn Nagamasa to order the riflemen to fire. It then becomes blatantly obvious that Mitsuhide wanted to kill Nagamasa all along and that he wanted to break Oichi in the process as well, and that he likely did all this for kicks.
Nobunaga himself is most definitely one of these, even if he's not as flamboyant as Mitsuhide. After Mitsuhide broke Oichi, he didn't bat an eyelash at it. He thinks his own wife is nothing to him and constantly puts his sister down and enslaves her to his will. He is also said to be made of pure evil from what Masamune gathers in the anime's last battle, so he certainly lives up to this trope.
Another historical anime, Rose of Versailles, we have Jeanne of Valois-Saint-Remy, the person who brought down Marie Antoinette and started the Revolution. Her first Moral Event Horizon was when her sister Rosalie managed to find her after she conned her way into nobility, she had her lover whip her and nearly kill her to drive her off. Her second? Killing the kind noblewoman who took her in to inherit her fortune. Third...the entire diamond affair. Note, in the manga she at least has the trait of loving Nicolas, her lover and later husband. In the anime...she doesn't. All she loves is money and herself.
