Monster is dedicated to exploring whether there is such a thing as Pure Evil, or if anybody, no matter how heinous, can be redeemed. The series' conclusion is that while anybody can be redeemed, it is titular character Johan Liebert's refusal to seek redemption that makes him a monster. A sadistic chessmaster and manipulative bastard since he learned to walk and talk, Johan is on a personal journey to become, in his own words, as dark as possible, all while trying to find out if there is anyone as evil as he is out there, or failing that, force the heroic Dr. Tenma, and/or his own pacifistic sister, Nina Foertner, to kill him in cold blood. In this way he hopes to establish that even the best people can become just like him. Along the way he convinces children to jump from rooftops, gets a recovering alcoholic drunk before throwing him off a building, and convinces various serial killers to murder every foster family he has ever lived with, as part of his quest to become an unperson. Numerous Freudian Excuses are proposed for Johan's behaviour, yet each and every one is ultimately undermined, revealing that in the end, Johan simply is what he is, and what he is, is pure, unadulterated evil.
Hayao Miyazaki isn't fond of villains and when it comes to antagonists, his movies are chokful of either (initially) villainous characters who turn out to have a good side to them as well, or "good" characters who turn out to have a few nasty tricks upon their sleeve. There is one subversion in the Ghibli canon, however; Castle in the Sky, which features Colonel Muska, a government secret agent on a mission to retrieve Laputa. Once he does, at the expense of the heroes, he reveals he is the descendant of the Laputean monarchy, forces his way to the middle of the floating island and starts utilizing it's sheer force to turn on everyone. While he sheds his Affably Evil front, he gleefully kills most of his allies by throwing them off the island to their deaths, thus crossing the Moral Event Horizon. Basically, Miyazaki's only true villain suitably plays this trope straight.
On the subject of pre-Ghibli works, Future Boy Conan's Lepka is essentially Muska's spritual predecessor and equally as evil.
Osamu Tezuka's manga MW features the single most hateful and sociopathic character Tezuka has ever created, Michio Yuki, who is a blackmailer, bisexual rapist, kidnapper and murderer. In one chapter, he seduces and kills (for sexual thrills) the daughter of the president of the bank he works at, fakes her kidnapping, (anonymously) extorts ransom money from her parents, then robs her father's bank and pins the robbery on the dead girl by impersonating her and finally kills her father by making him lose his grip on a precipice by throwing lit matches into his mouth.Michio does this for his own amusement. His crowning achievement would be stealing a classified military neurotoxin and slaughter as many people as he can with it in vengeance for his own mortality. He doesn't succeed, but still manages to fake his own death and get away clean. To see the man who created Astro Boy come up with someone this messed-up rattles the eyeteeth more than a tad.
Black Lagoon is a Crapsack World, filled with terrible people, but none manage to be quite as hateful (or fundamentally petty) as Chaka. A Yakuza lieutenant with a penchant for Domestic Abuse, Chaka makes his entrance beating up Rock in an effort to impress Revy. When the battle between the Yakuza and the Russian mob goes badly for the Yakuza, Chaka kidnaps and brutalises Yukio, his boss' teenage daughter, beating her bloody, and planning to sell her to a sexual sadist as part of his plan to take control of the remnants of the Yakuza. When Revy and Ginji arrive to bail her out, Chaka shoots through his own men to try and get at them, kills another man for daring to try and run away, then runs away himself, leaving his men to be massacred. Childish, stupid, and completely out of his depth, Chaka manages to make an impression only through his complete lack of conscience, loyalty, or human decency.
Blade of the Immortal brings us the truly despicable Shira, who's just around the level of Yujiro Hanma in his depravity. He murders a Hooker with a Heart of Goldwho was just in the business to pay for her mother's medicine, because he enjoys cutting up women and making their muscles seize up during sex. After that, he savagely, gleefully tortures an assassin with his saw-edged sword and severs the leg of the unarmed woman that led him and Rin to the trap. After losing both of his hands to Manji, Shira is saved by his employer, who asks if he's chosen a new set of hands yet; he raped a hooker (to death) and young boy (who provides his new pair of hands) all night long in his cell. Later on, he mutilates and brutally cuts a woman to pieces, gags her with her own dismembered hand, impales her through the breasts, and rapes her to death, while eating parts of her corpse. After finding Rin, he strips her of everything but an open shirt, tied huge rocks to her feet and left her tied to a dock, half submerged in water during winter. It's exceptional how well Shira can execute numerous baits of actually appearing sincere. His heartfelt speech to Rin aims to drive in how he killed and ate her dog. Helping Renzo seek revenge is aiming to Force Renzo to be a sex toy for Shira's abusive benefit. Truly emotional pleading of Renzo to call off his revenge ends with a spiteful "never listen to men like me!", which thus end up putting the latter in even worse a state than before. Eventually, Shira gets saddled with one of the most satisfying ends ever written for a manga.
Anotsu Kagehisa's grandfather responds to a girl rescuing his grandson by stringing her up from a tree, bleeding and beaten, to be devoured by packs of wild dogs.
Hyakurin's husband slices his own 8-year-old son in half, because the boy was too weak to swing a sword and killed his own infant daughter simply because she was a girl.
Interestingly, Araya Kawakami is a subversion: he used to be a depraved bastard and is now desperately trying to bury the past so his son never knows what he really is - and he's willing to murder anyone, who gets in the way of that. He does manage, despite his crimes, to retain a measure of sympathy.
The manga version of Hagatai from Bokurano seduces his girlfriend's middle school aged sister, convincing her that he loves her, only to then have her gang-raped. He then blackmails her into staying silent, while he moves on to his next target. His motivation, beyond ephebophilia, is the sick thrill that he gets out of hurting her, while knowing that her family continues to trust him. He may not have been an alien, or the operator of a Humongous Mecha, but when it comes to being just plain disgusting, no one else in the manga comes close.
Norose Genichi, the Big Bad of Chaos;Head, is a sneering, arrogant, sadistic bastard with a god complex who specializes in Mind Rape, especially of young girls. What he did to Sena's family (and most especially the amusement he felt about it) was so far over the Moral Event Horizon that it begs belief and that was one of the first things that the audience knew about him!
Luciano Bradley, a hired psycho and Knight of Ten from Code Geass, is even known to be a vile bastard in the eyes of most of the other characters in the show. Fearless Action Girl Kallen is visibly frightened the moment she finds out she is in the same room with him and the fact he implies planning to rape and torture her doesn't help alleviate that fear. He also kills his own men without a care (whether needed or not) and loves to kill people slowly using his mecha's energy drill while asking them what's the most important thing for them. Luciano Bradley does get a backgroundof being abused by his parents and, as a child, killing his abusive father apparently in self defense. However, it isn't even talked about in the actual anime, just in supplementary materials and he isn't the only character in the series to have abusive parents. Luciano doesn't have a single line of dialogue in which he isn't insulting, threatening, or otherwise expressing a desire for hurting someone. and at several points comments that his only reason for being a soldier is because that way, he can kill as many people as he wants and not be punished. It's taken to the point where neither of his KOR allies, Suzaku (whom he almost killed for the hell of it, and whose deceased girlfriend he insulted) and Gino (whom he called a rich boy whose family name is the only reason for his position), seem to care at all when Kallen kills him in battle (whereas she and Gino even exchange some semi-friendly banter).
Here's the interesting atrocity that puts him in Moral Event Horizon: he killed Lelouch's mother Marianne purely out of petty jealousy and hid it from his father Charles. It finally gets his own twin brother, who was NOT an angel himself, to finally kill him after he has lost the battle with Lelouch. If you're making Emperor Charles look good, you're definately really bad.
The Director, Tamaki, is a Psychopathic Manchild in charge of managing the titular prison. He uses his position to initiate mandatory Death Games (he poisons EVERYONE and then sells the antidote in exchange for death game prize money). He forces the Deadmen to take part in Blood Sport and dissects the losers. He has scores of Mad Scientists working under him and created not only the Undertakers, but also the Forgeries.
The worst of them all is Hagire Rinichiro, the real director and Mad Scientist extraordinaire. He is so utterly evil he puts notable evil scientistAlbert Wesker to shame. The atrocities he committed include turning poor Shiro into the Red Man / Wretched Egg and being behind Tamaki's descent into bastardry. Essentially, he is behind everything bad that happens to every character.
In an episode in the second season, Heiji/Harley tries to beat Conan at a murder mystery. The banker and victim of the case was this, and he was killed because he ruined and forced to suicide his best friend just to get his hot (and pregnant) wife. Said wife was so disgusted once she found out, that she pretended to lose the baby girl but secretly sent her to a convent to keep her away. Several years ago, the girl came back and started working as a maid for the banker, not knowing what her relationship with the family was. When the wife found out the banker was planning to do to her daughter and her boyfriend what he'd done to his old friend just to get at her...well, you see what happened. (He wasn't aware at first, but when she told him, he simply brushed it off.)
Yutaka Abe/Mark Newman on the episode "Flames of Confusion". Most perps on this show usually have a motive that the audience can sympathize with and show regret at the end, but not this guy. He killed his friend from college 20 years ago for the insurance money—don't ask how he had a policy. He used his company and employees to try to build the perfect alibi. Everyone thinks he's suspicious. Even Detective Mori/Moore, who usually suspects the wrong guy, is right on the mark, but no one is able to solve the case. And when Conan blows open his case anyway and confronts him in the airport parking lot, where Abe is trying to flee the country with his money, Abe attempts to murder Conan brutally, but Conan's soccer skills win the day anyway. Oh, and after he's arrested, he angrily condemns the 'brat' who caught him. Basically, when this guy is first interviewed for the case, he had a completely inappropriate tone for his long-time friend just dying, and when Conan finally catches him, his facade drops and he almost looks, sounds, and moves like a real monster.
Hougen from Ginga Densetsu Weed is possibly the most evil and malicious dog ever portrayed in any media or at least a strong contender for the place. He introduces himself to the legendary heroes of Ohu by taking a shit and telling them that if they eat it, he'll let them go. He then paralyzes the heroes by threatening to kill a young female, Reika, if they dare to fight back. He has the heroes beaten almost to death as a result. Hougen frequently laughs at pain and desperate acts of heroism and defiles the corpses of those he's defeated; in one snowy scene, he sits on a recently dead dog to keep warm and jeers at the fallen's companion that he'll sit on him next when he dies. Hougen is not above using his lackeys as expendable shields, sending dozens of them to their deaths against opponents whom he can beat himself. When he has temper tantrums, he brutally kills whoever happens to be standing around. Hougen is also a serial rapist, who demands his underlings to round up females for him. He forces Nero (then-pack leader of one of the main characters, Lovable Coward GB, and a minor villain) to kill the abandoned puppies right in front of GB (GB was about to look after them but brought them at the wrong time) just to prove that the puppies weren't Nero's - and that Nero, therefore, isn't hiding a female from him. This, by the way, doesn't save Nero's hide in the end. Later (chronologically) Nero encountera the leaders of Ohu and is swiftly cowed into submission by them trying to justify his cowardice to Hougen by saying that they threatened to bite off his legs and piss on his face. Hougen immediately makes an example out of him by doing exactly that. Even finding out that Hougen and his brother were trapped by their human owner for so long that they had to resort to cannibalizing the dogs trapped with them does nothing to evoke sympathy for his cruelty. The only smidgen of honor Hougen shows throughout the whole series involves a pact he and his brother made, that if Genba dies, he wanted it to be by Hougen's fangs. When Genba suffers a head wound that drives him psychotic, Hougen murders him. Then promptly turns on the dogs who were with his brother, tears out their throats and hurls them from the top of Gajou.
Hakumen no Kono from Ushio And Tora qualifies as a Complete Monster from the first few chapters of his introduction. He's literally born from hatred and rage from Tora when he was human, thus has no positive qualities. He delights in destroying countries, having done so for thousands of years until 800 years before the story he was hit by the Beast Spear, and Japan's Bakemono and Human population teamed up to defeat him. In response, he holed himself up below Japan...and if he was removed, the entire country would sink. From both Ushio's and Mayuko's families, a Barrier Maiden is chosen to keep him imprisoned...but after 800 years, he got stronger. His worst acts are during the time between the weakening of Ushio's mom's barrier and his awakening. First he sends his Bushin's out to attack the Kohemei Sect and Japan, one of which manipulates an boy named Kirio by becoming his mother figure. Then he uses a special type of demon to systematically wipe out everyone's memories of Ushio and Tora, including Asako and Mayuko. When he awakens he ceases no time whatsoever causing fear and hatred by nuking an entire island'TWICE while Japan sinks.
Akakabuto, from Weed's predecessor, Ginga Nagareboshi Gin, is literally a complete monster, since he is a gigantic bear out on a rampage killing anybody that crosses his path. He enjoys killing for the sake of killing and is defined by an intense hate towards anything living.
The leader of the Millennium, The Major, launches an attack on London that results in the death of nearly its entire population overnight, slaughtering civilians with impunity and toothy grins. One of his men is even seen with a dead baby in his mouth. They are not doing it out of revenge for losing WWII or revenge for Hellsing's shenanigans that derailed their plans during said war. The Major says they have no real reason to do this; he reallylikes war (and gives a 5+ minute long passionate speech explaining his love for it).
Zorin Blitz lays siege to the Hellsing mansion with her forces and mind rapes Seras by delving deep into her memories and forcing her to relive her painful childhood, where she had to watch her parents be murdered by gangsters and her mother's corpse being raped. While Seras is trapped in the illusion, Zorin hacks off her arm, stabs her through the back, and cuts her eyes. Pip and his two remaining squad members arrive and manage to temporarily disable Zorin by shooting her multiple times. Pip tries to escape with the badly wounded Seras, but Zorin kills him by stabbing him through the back with her scythe. To top it all off, as Seras cradles his dead body and cries for him, Zorin mocks Pip, calling him an "insect", and prepares to kill Seras and her fellow soldiers. This was enough to provoke Seras into absolutely curb stomping Zorin and her forces to death and pulling a No-Holds-Barred Beatdown on Zorin by scraping her face against the wall at superhuman speed until her head remains as nothing more than a red smear on the wall.
Jiro and Saburo from Ichi The Killer are twin brothers, whose sibling rivalry makes them bring out the worst in each other. It's hard to say what's the most terrifying about them. These unnerving twins ooze tension whenever they appear and their uncanny faces like parodies of humanity with features squashed together only add to their scariness. Their actions are so violent and insane that even their fellow Yakuza gangsters are shocked and disgusted. The twins keep marathoning further and further beyond the depravity line and by the time Saburo rapes a girl to death by shoving a sword in her vagina, you barely feel anything.
Dio Brando. He has no compunctions forcing people to do his bidding, and if they do that, it's no guarantee of survival (think the rich man who drives him around in Part III). His shadow also looms large over all antagonists that follow him, with all of them being connected to him in some way, and he's directly responsible for the events of Part VI, where all the main characters die. He used his time-stopping stand to force someone to eat a dead cat and stab someone else in the face - and he did this just because he could. In Part I, after being adopted by Jonathan Joestar's father, he proceeded to make Jonathan's life a living hell for no adequate reason. He beat up Jonathan, humiliated his girlfriend, burned his dog alive, tried to poison his father, and forfeited his humanity to become a nigh-immortal vampire. Dio then embarked on a killing spree across London, with his atrocities including cornering a young woman, who begged Dio to spare her baby. Dio agreed, promising not to kill the baby, but killed the woman only to revive her as a zombie. True to his word, he left the baby, but watches as the zombified woman proceeded to eat her own child in front of him. He refused to die after being defeated, with his severed head returning at the very end to attack the cruise ship Jonathan and his new wife are on, thus sinking it, leaving few survivors. Jonathan drags him to the bottom of the sea with him, finally killing Dio...until he returns 100 years later, using Jonathan's corpse as a body for his severed head. Even though Dio had a hideously abusive father, his Freudian Excuse isn't nearly good enough to excuse his barbaric behaviour.
Cioccolata. For starters, his back story involves him torturing old people to death while maintaining a guise of being a good samaritan. When he starts fighting the heroes, he makes sure that he starts horribly killing the innocent people in the village just for fun. His Stand Green Day works when people are at a lower altitude than him, so what does he do? He gets on a helicopter and flies above Rome to kill as many people as possible. It says something when even the Big Bad Diavolo, a man who would kill his own daughter to protect his identity, is disgusted by him. Thankfully, Giorno proceeds to give Cioccolata the biggest and longest beatdown in the entire series, which sends him flying into a Garbage Truck with "Combustable Trash" labeled on the back.
Magic Knight Rayearth is a show notorious for giving all of its characters a sympathetic, or at least understandable, motive for what they do. Nobody is a Complete Monster here. Except one: the Big Bad of the second season of the anime, Lady Debonair, an Eldritch Abominationborn from the collective fears of Cephiro's people who wants (just like the above-mentioned Wiseman, and possibly Yuki and Johan) to destroy the world for no understandable reason, cannot be reasoned with, and will use any despicable trick in the book to get her way. Even reading this does not convey how horrible she is, but when she abandons her own "daughter", Nova, to her fate after she fails in defeating the Magic Knights...well, that's when it truly sinks what kind of monster we're dealing with.
All of the psycho killing and betrayal in the anime Mai-HiMe is ultimately a result of Nagi's direct and indirect manipulation. He gives the girls their powers and then creates monsters for them to fight in order to train them to use violence to solve their problems. Then he manipulates a few characters to get the massive betrayals and killings we see in later parts. It is not clear exactly why he does this (though he laughs his head off over the betrayals and fawns over the killers) or who he is. Supposedly, he is just serving the Big Bad of the story, but the Big Bad is more of an Orcus on His Throne. At the end, Nagi seems to imply that he himself is an immortal demon and that, though the Big Bad is dead, Nagi can't be killed and will be back.
Tomoe Marguerite started out as a manipulative bully and Alpha Bitch who was in love with Shizuru, but after joining the Schwarz, she refused a Last-Second Chance to rejoin the Alliance and threatened to kill them all because she enjoyed making people suffer and the lives of everyone but Shizuru was meaningless to her. She later says she does so because she "always get[s] what [she] want[s]", pretty much cementing her "heartless bastard" status in the eyes of a lot of fans. Her Karma Houdini status doesn't help.
Nagi, the Big Bad of the setting, is a dictator who takes over Windbloom, releases forbidden technology, and starts a world war, supposedly to encourage evolution, but in the end, he reveals he just wanted to see if humanity would kill itself if given the chance. He is taken lightlyat times, especially before he puts his plans fully into action, but it is clear that he has no morals and everyone obeys him out of fear.
In the manga, Tomoe is Demoted to Extra and displays none of the repulsiveness of her anime counterpart. Her Complete Monster credentials are passed over to Big Bad Sergey Auguste Taiki (a far cry from his Punch Clock Villain counterpart Sergay Wang in the anime), who believes that the world is full of lies and needs to be destroyed for things to be put right once again. Not only is he abusive and cruel towards protagonist "Manshiro", and not only does he manipulate most of the cast, but he also frees the dark HiMEs and manipulates the Not Quite Dead real princess Mashiro in order to achieve control over Dark Mai and Fumi, using them as weapons to achieve his ambitions. Then, with Fumi under his control, he murders Mashiro when he didn't need her anymore and starts wreaking havoc on the world, while raving that the truth doesn't exist and that the "fake" world needs to disappear. He is only stopped by a Big Damn Heroes moment from Ensemble Darkhorse Erstin and a spectacular Combination Attack from the main Power Trio (Arika, Nina, and Ers) that takes out Fumi. As he lays dying, though, Sergay gets one last hurrah and manages to trick "Manshiro" into coming close, nearly killing him, stealing his Pure White Diamond and going One-Winged Angel to completely destroy the world. "Manshiro" turns out to have survived somehow, though, and with the help of all the Otome put together, he destroys Sergay after giving him an awesome "The Reason You Suck" Speech, pointing out how Sergay never loved anyone, not even himself. A pretty bad SOB, to be the counterpart of an overall decent person, huh?
Admiral Haruki Kusakabe from Martian Successor Nadesico establishes himself as a very detestable person near the end of the TV series, by framing Tsukumo Shiratori for treason and having his former best friend Genichiro "mercy-kill" him, all in order to prolong the war between Earth and Jupiter and have a chance to seize Mars' forgotten technology. He is finally discovered and forced into exile, but plotting revenge...and what marks his real entrance into Complete Monster territory is the fact that, in the three years between the series and The Movie, he had Akito and Yurika captured and experimented on to replicate the Boson Jumping effect. The experiments permanently hooked Yurika up to a machine, in a catatonic state, and completely destroyed Akito's senses, leaving him an empty, tragic shell of the innocent boy he was. He's also a Karma Houdini, so it's even more infuriating...and it makes it even more cathartic when you get to kill him off in some Super Robot Wars episodes. Preferably with Akito and Gai's Double Gekigan Flare...
His Karma Houdini status would have probably been undone in the sequels, but, since Word Of God is they've all been cancelled with no chance of ever being made...
There is also Yoshio Yamasaki from the same movie, the Martian Successors' resident Mad Scientist who was directly responsible for doing all those horrible experiments on Akito, Yurika, and Lapis - and possibly on a lot more people before them. This guy is the most chilling character in the whole Nadesico series: there is something about his cheerful and friendly demeanor, even as he's committing all those atrocities, that only manages to make him more horrific. It's not that he enjoys his cruelty. He just has no feelings whatsoever about it. To him, ruining countless people's lives or mind-raping an innocent girl into becoming a mindless machine is just as mundane as brushing his teeth in the morning. Think about it - he won't even have his conscience to answer to; he has no conscience, period. He's just pure intellect unbrindled by emotion. Think an evil version of Lloyd Asplund, make him a hundred times worse, and you've got Yamasaki.
Apos from Mnemosyne, with his golden hair, crimson eyes, and beautiful features resembles an angel. The truth is markedly different. Apos is an immortal who finds amusement in suffering and agony. Apos hunts down female immortals and rapes and tortures them physically and mentally to consume their 'core' of immortality. The suffering improves the taste. Apos's obsesses over the heroine Rin Asogi and has his female subordinate Laura disguise herself as Rin to ruin Rin's name with a series of murders, and also satisfy his lust by raping her. At one point, he brutally crucifies and rapes Rin's best friend and lover Mimi simply because he was bored waiting for Rin's arrival. Apos is behind nearly every evil plot in the series and engineers a plot to turn the world against immortals and turn on itself by causing a nuclear explosion with an immortal seen as a survivor, before revealing the world tree Yggdrasil to the world to have humanity infected with the time fruits and become immortal so he cna harvest them at leisure. Apos betrays Laura and forces Rin to kill her old lover apos had turned into a carnivorous Angel in self defense, before personally executing her current lover (Apos's own father) and attempting to sacrifice Rin to Yggdrasil. When asked what he wants with the world, Apos's response is simple: I want to taste it!
Sayara Yamanobe, second only to Apos, is a repulsive, callous scientist, who masterminded the cloning program that killed the original Koki Maeno. She keeps the failed test subjects as ravenous, flesh-eating zombies that suffer every moment they're alive. When she has Rin in her care, Sayara proceeds to molest and then torture her to death while it's more than just implied that she molested and raped Koki as well, also being hinted this is routine for her. Sayara later just attempts to wipe out all human life and she would be the morally lowest character in any other series, so it says a lot about Apos that he's the lowest, the most depraved and the most disturbing one in Mnemosyne.
Tenzen Yakushiji from Basilisk manages to be the most evil of a series, which is basically evil versus evil. This extremely ruthless ninja plays both sides of the conflict between his Iga clan and the Kouga clan for his own benefit. He ignores the code and pride of his clan, which even the most disgusting rapist, Nenki, follows by enlisting the aid of one of the Shogun's concubines. Tenzen drives Kagerou Kouga to a mental breakdown and attempts to rape Princess Oboro twice, which may be why viewers find him the easiest to hate. When Oboro regains her sight, she uses her nullifying powers to make Tenzen's head blow up.
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 a cop, who thinks he's making justice by sending the girls he rapes to kill other criminals. He killed Sawa's parents, raped her many times when she was a little girl, turned her into a killing machine and kept her at his service by giving her earrings filled with her parents' blood, aside from having put other girls through similar treatment. The permanent smile on his face shows that he has no remorse at all. The lack of remorse is accentuated by his slightly retarded partner-in-business-and-raping, Kanie, acting as a foil for Akai, who is perfectly aware and proud of the atrocities he commits.
Keith White in Project ARMS 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. Although the 1941 Hitler is his role model(itself an obvious indicator), he thinks Hitler's greatest crime is not finishing what he started. 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..."
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.
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. The real reason is simply sadism.
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.
Hellmaster Fibrizzo of the second season and eighth Light Novel. 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 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. 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 shonen series 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.
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. He molests Satella again, gets Holly and Satella to fight, beats Kazuya and becomes gets away with everything afterwards by pulling the wool over everyone's eyes again. 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. To make this even worse, he somehow pulls aHeel Face Turn.
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.
The man's called Vicious. What the hell else would you expect from him?
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. 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. He 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, demonstrating 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 what fans find to be 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 likely very hard for viewers not to enjoy that particular scene. For further satisfaction, Kazuya's friends Kyoshiro and Nana stop Kazuya from beating Miwa to death, proceeding to explain that even the human government has enough of Miwa, implications being that he'll face a trial and won't be able to get any position in the government ever again.
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.
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 way 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.
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.
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.
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.
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
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. 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.
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. 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.
Tommyrod is one of the Sous-Chefs of the Bishokukai Organization in the Toriko series. While he puts on a rather Affably Evilfacade with his subordinates he is utterly ruthless and won't hesitate to kill them if failed. His powers use Body Horror insects he keeps inside his body and he doesn't hesitate to sacrifice them, even with high capture levels. He takes sadistic joy in tormenting his opponents, or even bystanders like the unfortunate hunters he encountered in Ice Hell, and his brutal fight with Toriko just shows how much joy he has in inflicting pain on others. Its taken to extremes when he kills Komatsu's baby wall penguin's parents for absolutely no reason, just wanting to enjoy the suffering he inflicted.
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.
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. 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.
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.
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.
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.
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 couldn't stand lasting peace, so he incited a civil war, which he's still actively maintaining, in his own country 20 years ago. During said ongoing civil war, one of Jenazad's servants informs him that the men, who joined his side, 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?" For his research purposes Jenazad causes his past students to fight and kill each other. He causes an avalanche to kill his own modern-day YOMI student, who, granted, isn't a very nice guy himself to begin with(except he survives). Jenazad also almost manages to trick fellow YAMI member Akira Hongo into killing the titular protagonist as well as kidnaps and brainwashes Furinji Miu into becoming his newest cold-blooded disciple. He later supervises the brainwashed Miu's battle against Kenichi, with the expressed purpose of getting her to kill Kenichi, following which her mental state will be completely subject to Jenazad's manipulation and the brainwashing process to convert her into his thinking will be complete. Jenazad detests peace so much he is willing to kill his country's deposed princess (the sister of the aforementioned 'dead' YOMI disciple), who is all for restoring peace to the nation. Silcardo Jenazad winds up being the only Nine Fist member to get killed off for real - by a fellow Nine Fist, the aforementioned Akira Hongo, no less.
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.
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 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 until, to Haydee's luck, the Count stops him and orders him to leave.
In Perfect Blue, Me-Mania is an example of a very creepyfan with an obsessive crush. He's first seen admiring Mima on the stage and doesn't come across as threatening, even stepping in to defend Mima from heckling audience members. Unfortunately, after Mima quits her singing job, Me-Mania starts murdering people connected to her and appearing at sets before disappearing just as quickly, another eerie thing in the film besides Mima's madness. Near the end, Me-Mania, re-enacting an earlier scene of Mima acting like she was being raped by a group of men, attempts to rape and kill her for real, all the while throughly enjoying himself. His ugly appearance highlights how ugly he is on the inside.
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.
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.
Akio from Revolutionary Girl Utena is the epitome of heartless, callous selfishness. Once the heroic Dios, Akio grew disillusioned with being the hero and allowed his sister Anthy to be tortured for what amounts to centuries. As one of the prime figures at Ohtori Academy in the present, Akio seduces many high ranking figures (including his fiancee's mother) in order to manipulate them and runs the Rose Duels that essentially pimp his sister Anthy to the victors, abusive or otherwise. Akio gains a cold enjoyment out of mentally ripping apart those near him, including his fiancee who it's also implied he's physically poisoning to get her out of the way. He views Anthy as nothing more than a means to ultimate power and when at one point she's hesitant to continue their weekly tryst one night, he angrily rapes her anyways. Akio seduces Utena and takes her virginity, manipulating her feelings for him to send her into a final confrontation to be sacrificed for his 'revolution,' where he will rise above the world. Akio views people around him as nothing more than pawns or toys, to be mentally or physically used and discarded as his plans or his whims demand.
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 of humans being worthless. One ofthe crueler of his deeds is implanting 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. All the while, he admires his work, is proud of the bloodshed and 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. The First Friend (Fukubei) is simply an egocentric asshole sneering at 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. The Seconds Friend's actions, on the other hand, are even more extremely horrible than the ones of the First. Then again, even though the Second Friend is revealed to have had a truly horrid childhood to the point of contemplating suicide - it doesn't manage to engender sympathy.
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.
The Duke de Guemenee kills a boy named Pierre right after promising not to hurt him after he had stolen his wallet out of hunger. He laughs after gunning the boy down, and Oscar has to be restrained not to throttle him.
The lord of the Hioki Domain in the first series of ''Kamui Den": among many other misdeeds, he rapes a peasant girl who was serving at his residence, then after she's drowned herself in despair, he spitefully hacks up her corpse and sends it back to hvillage, bundled togther with rotting animal meat.
The Director from Pure Trance qualifies. The story never presents any positive traits in her, and gives plenty of reasons to loathe her. She is shown as being directly responsible for the deaths of two of the nurses working under her (one of whom she kills by force-feeding her poison pills until she bursts), in addition to being an incredibly negligent surgeon who has killed many more women through her incompetence. Her Establishing Character Moment is stabbing and killing the mother of a woman she killed in surgery (by placing a pornographic magazine in her abdomen instead of the necessary organ). The Director is an unrepentant drug addict as well, stealing medicine needed by her patients for her own recreational use; while on drugs, she becomes even more wildly violent and unstable. In what is arguably her absolute worst moment, she attempts to freeze-dry two barely-born twin children and turn them into a pair of earrings.
Count Heinrich von Kinkel from Tsukuyomi: Moon Phase was always a nasty customer, with his habit of sadistically tormenting and trying to murder the majority of the cast. As one of the eldest vampires around, Kinkel believes anything around him is a toy for his amusement or enemy to be destroyed without mercy. It's revealed in flashbacks of his fledgling Elfriede that Kinkel seduced a human woman, drove her insane and returned many years later when the daughter was a teenager. Kinkel turned Elfriede into a vampire before slaughtering the human family who raised her. He then forced her to drink the blood of her best friend, gloating how Elfriede was his slave. When Elfriede was done, Kinkle proceeded to gloat that her pain gave him joy to no end. I Hate You, Vampire Dad doesn't begin to cover it.
It was suspected since his very first appearences that MykageTowano from Aquarion Evol was bad news, and this impression turned out to be absolutely right. Sure, it was clear that he was never of Altair's side, and was just pursuing his own interests... and then, in Episode 13, he crossed the Moral Event Horizon (or, at least, got a pretty big Kick the Dog moment) by killing his Anti-Villain subordinate Jin right when he was about to have an Heel Face Turn, in front of the girl who loved him no less. And then Mykage even had the gall to perform an eulogy for Jin in front of the inhabitants of Altair, in order to better manipulate them to his will. With the series coming to a close, he's now pulling out all the stops, and it's clear that there's no low he would not sink to in order to get his hands on the original Aquarion and have his revenge on Amata and Kagura - for the "heinous crime" of being the two halves of the Winged Hound Pollon (It Makes Sense in Context). It was not bad enough that he manipulated Zessica when she was at her most vulnerable in order to make her his pawn and pull a Grand Theft Me on her, but in Episode 24, he went as far as murder Alicia just to gain a momentary distraction, and then mind control Kagura, the resident Jerkass Woobie, into killing his own father Izumo (another Anti-Villain). In fact, Mykage is an example of this being a Justified Trope, as he turns out to be the incarnation of the hatred harboring within Touma (the Big Bad of the previous series, so it makes sense that he's pretty much Made of Evil.
In Reiko The Zombie Shop, Saki Yurikawa is a mentally messed-up, knife-wielding serial killer obsessed with finding little girls to replace her dead ( actually comatose) little sister. When the girls refuse to comply or make Saki made in any way, she snaps. Her two debut stories in the first volume, Dead Sister, reveal that she has already murdered over thirty little girls, including one of her classmates, an investigative reporter, her cameraman, and Reiko Himezono herself. In the case of the investigative reporter, Saki had threatened to murder her daughter if she didn't get to her apartment in ten minutes. The reporter managed to get to the apartment in time. Saki already killed her daughter. In the battle against Reiko, Saki finally gets her Laser-Guided Karma by way of Reiko summoning a portal to hell, where Saki is greeted by her many victims. All this despite Reiko being reduced to a severed head. In the next volume onward, Saki is now forced to silently serve Reiko as her personal zombie.
Emi has stolen and copied numerous paintings and passed them off as her own while espousing what a great talent she is. She then plots to steal a painting created by Saki Asamiya's friend Junko. And for good measure, has her kidnapped, drugged, tortured, and raped over the course of a week until she's finally killed. Although it's possible Reimi was responsible for the latter.
Ayumi is, oddly enough, the least evil of the three sisters, as her antics besides the bus crash mainly including drug dealing and racketeering throughout the high school.
Reimi is by far the worst of the entire family. The bus crash was her idea, and she herself is quite good at putting on the facade of being the White Sheep. Adored by the student body as a Madonna-type figure, Reimi uses this to her advantage when she decides to brainwash her students for her personal army. She then gives Ayumi a rigged shotgun, steals all her money, has one of her brainwashed lackeys kill Emi and Gozo (and the herself), and then laughs about "her poor sisters. During her rooftop battle with Saki, Reimi drops the princess facade and reveals her true Ax Crazy tendencies as she savages Saki with a whip while screaming at her about her supposedly insane mother.
Luuza Luft from Aura Battler Dunbine (by Yoshiyuki Tomino, again), an Evil Matriarch of the worst kind who plots against her own husband (who, despite being the Big Bad, comes across as more sympathetic than her) to have the power all to herself and her lover Bishott (and it is doubtful she has any loyalty to him as well). She will do absolutely anything to get what she wants, including murdering her own daughter in cold blood, which she threatens to do in an early episode and actually does prior to the bloody finale. Her Karmic Deathat the hands of Rimru's heartbroken boyfriend is both brutal and highly satisfying.
Baki the Grappler's Yujiro Hanma, definitely. He beat the everloving crap out of his own son, titular Baki Hanma, so that Baki's entire body, except his face, is covered in scars, killed Baki's mother, and then beat up Baki's friends and allies just to show he could, ALL IN LESS THAN AN HOUR. Yujiro has enough Charles Atlas Superpower to be effectively untouchable by police and authorities (even the military) and uses his abilities to do whatever suits his fancy without repercussions to put relentless psychological pressure on his son (including, but not limited to, threatening to kill his girlfriend if Baki fails his expectations, and to subject Baki's possible children to the same abuse he had piled on Baki), just to create an opponent worthy of himself. And that's not counting the thousands of people he murdered since he was at least sixteen, or the fact that every fight we've seen him in ended in him delivering a No-Holds-Barred Beatdown while grinning like a maniac, just because it's the sadistic bastard's idea of fun. Or how he treats his other son (i.e. less than dirt on his slippers). Baki puts himself through Training from Hell and a series of incredibly brutal martial arts tournaments just to become able to protect himself and his loved ones from Yujiro. The worst part is that Yujiro hasn't got his comeuppance yet - after about 600+ chapters - although this is somewhat understandable, as his defeat probably would end the series.
Yonemi Kamon from Battle Royale is the administrator of the Battle Royale Program, where high school students are forced to kill one another. His hobbies are watching students kill each other, killing students and joking about said students' deaths. After taking a schoolbus full of students including Shuuya and Yoshio to be transported into the Program, he later tells he also went and raped an orphanage director Shuuya and Yoshio had grown close to (just in case you didn't already get he's evil). What makes Yonemi so noteworthy (and awesome) as a villain is that unlike the movie portrayal of the Director, he doesn't even pretend to buy into the crap about maintaining order or protecting the honor of the Empire. He enjoys raping and killing, and he's a huge fan of the Program because he gets to see teenagers deal with gut-wrenching emotions before dying horribly. Even soldiers are visibly nervous around him. Considerable is also how he goes out. When the teacher is killed in the movie, it's because the main character shoots him. In the novel, Shogo Kawada shoves a sharpened pencil against his throat, killing the teacher. In the manga, they shove sharpened pencils into his nostrils and slam his head against a desk, which many readers think of as highly earned a demise for the character considered one of the most evil men ever depicted in manga.
The Unknown Man is indisputably one of these. In order to find our protagonist, he crafted a radar system made from a silpelit who was still alive, by cutting her lower half. In order to make sure that she wouldn't use her powers against him, he also built a tank for her which would keep her in a constant state of excruciating pain. He also felt it would be a shame to let said diclonius' body go to waste, so he, in no grey terms, raped her before he cut her legs. Finally, just when you think this guy couldn't get any more repulsive, he attempts to rape Mayu. Needless to say, when Bandoushows up and kicks his ass, it's quite satisfying.
Mayu's stepfather qualifies. He is a child molester who loved to sexually humiliate her, and it's shown he went as far as to sodomize her. He gets no comeuppance for this, as he's only shown in flashbacks.
The Nighmare from Kirby of the Stars made the demon beasts seen throughout the series. He eliminated an entire La Résistance group save for a few survivors and likes making monsters and terrorizing planets (Popstar soon to be one of them), just because he likes doing it. He also sped up the asteroid Gerath's course to crash into Popstar itself.
From Naru Taru, Aki Honda, the most sadistic Alpha Bitch that could only have come from Mohiro Kitoh's warped imagination. She bullies one of the protagonists by forcing her to eat worms, then rapes her with a glass test tube and threatens to kick her in the belly while it's inside her.
Gemma, the Big Bad of Ninja Scroll. The other Eight Devils of Kimon are all nasty pieces of work, but he surpasses them all with his callous disregard for anyone, lover, friend or foe, just so he can feed his bottomless greed. From infecting a town's water supply with the plague just because they're too close to a secret he wants to keep, to betraying and killing his employers who'd revealed him that secret in the first place, to orchestrating massacres running in the thousands, to killing Kagerou, The Woobie to end all woobies out of mere convenience and malice, there's just no low he won't sink to. And sinkhe does.
Gyokuro Shuzen, the leader of Fairy Tale. Her goal is nothing less than the complete eradication of humanity, and she is willing to unseal the Eldritch Abomination Alucard to do it. It's also implied that she was the one who raised Kahlua — her own daughter — descrbed as an Ax Crazy monster. She doesn't bat an eyelash at all when she orders the death of her daughters' friends, and was going to enjoy it. She shows herself to think of anyone, even her own daughters, as tools. She's the one who raised Kahlua as a reluctant killing machine, which Kahlua plainly hates being. She mocks Akua for being useless to her, implying she'd eliminate her in a heartbeat, and shows no regard whatsoever for her after Moka delivers a blow that could have caused critical damage. But then she promptly K Os Tsukune, and takes off Moka's rosary to control Alucard. The entire time, Gyokuro is taunting Moka with a friendly smile, clearly enjoying all the emotional and physical pain she's causing.
Sword Art Online has the main villains of the Alfheim Online and Gun Gale Online arcs:
Suguo Nobuyuki is the director of research and development at RECTO Progress Incorporated, and the one-time fiance of female lead, Asuna Yuuki. He was also completely obsessed with research into the manipulation of human emotion. Following the clearing of Sword Art Online, Suguo trapped three hundred of the surviving players in his own game, Alfheim Online, where he ran experiments on their minds, testing their fear and pain responses. Kidnapping Asuna in the game, he keeps her trapped in a gilded cage at the top of Alfheim's World Tree, while plotting to wed the comatose girl in the real world. When protagonist Kirito reaches the top of the World Tree, Suguo uses his administrator abilities to paralyse him, tortures him, and then sexually assaults Asuna in front of him, gloating the entire time about how, once he's freed, he will rape her again in real life. When the plan fails, he attempts to kill Kirito in the real world, attacking him with a knife. Guilty of attempted murder, torture, trying to rape a teenage girl, and putting three hundred people who had just spent two years fighting for their lives through an additional two months of trauma, Suguo is as bad as SAO's villains get.
Red Eyed XaXa (real name: Shoichi Shinkawa), one of the top three members of the Laughing Coffin Guild in SAO, and the Guild's Master Swordsman. During the Murder Investigation Arc in SAO, XaXa, alongside PoH, and Johnny Black ambushed and attempted to murder players Caynz, Yolko, and Schmitt; when Kirito intervened, the trio also tried to kill him. After making his way back to the real world, XaXa, bored, and seeking a way to kill again, took advantage of his younger brother Kyoji's fragile mental state, to convince Kyoji to create the online persona of Sterben/Death Gun in Gale Gun Online, ultimately hijacking Kyoji's desire to be "the strongest" for his own ends. Using Kyoji, and his old partner Johnny Black as aides, XaXa was able to arrange the murders of players Zekushiido, Usujio Tarako, Pale Rider, and Garret, before sending Kyoji to murder his own crush, Shino Asada. A sadist at heart, XaXa makes a point of crippling his opponents' avatars with a paralysing toxin before delivering the coup de grace, and during his Sword Fight with Kirito in GGO does his best to cut him to ribbons, mocking him the entire time.
Johnny Black (real name: Atsushi Kanemoto), one of the top three members of the Laughing Coffin Guild in SAO. As the Guild's Master Poisoner, Johnny came up with a way to paralyse opponents so that they could then be tortured to death, and puts this poison into effect during his, XaXa, and PoH's attack on the members of the Golden Apple Guild. When discussing what they will do with the captured trio, Johnny expresses a desire to make them fight each other to the death, promising the survivor that he or she will be released; when PoH notes that Johnny will just kill the survivor, Johnny complains about how the Guild Leader has ruined the surprise. He subsequently attempts to poison Kirito when he comes to the Golden Apple trio's rescue. Escaping into the real world, Johnny was recruited by XaXa during the Death Gun murders, poisoning Pale Rider and Garret in their homes, before again making a getaway. He was finally arrested when, after having lain in wait for six months, he attacked Kirito and Asuna on the street, intending to inject them with poison from a syringe, and hospitalising Kirito. Unable to quit killing in the virtual world or the real world, Johnny is the show's definitive Psycho for Hire.
Haguro Dou in Wolf Guy - Wolfen Crest epitomizes the fear of encountering a sociopath, especially a Fatal Attraction -style of obsessive one. For starters he manipulates the younger Kuroda into going Columbine on half the student body. Using weapons from his family gun cellar, the lad wants revenge against Inugami for his older brother's death, which in reality was caused by Haguro pulling the life-support. Haguro keeps going on the same line by beating his far more honorable subordinate Chiba within an inch of his life, biting off his tongue and then raping him for good measure to the point that Chiba ends up dying from a combination of ruptured organs, blood loss and broken ribs( before Inguami bringing Chiba back to life by giving some of his own blood. His reason for this is Chiba ending up encountering Inugami, whose werewolf-form Haguro is Yandere for, out on the streets and talking to him for maybe 15 minutes when Haguro isn't around. Haguro, not relenting or repenting, kidnaps Aiko Aoshika(a teacher who ends up falling in love with Inugami, becoming his Morality Chain). He repeatedly has Aoshika gang-raped by his Yakuza goons(also raping her himself), while recording it for Inugami to see and threatening Inugami through the camera with spreading the videos to the internet, which would ruin what's left of her life. He also gives her a Psycho Serum to make her go even more insane than such experinces already would, making the poor woman enjoy her own torture and rape, which almost destroys her physically and mentally. He does this in hopes of Inugami (who left to Nara due to Haguro's actions) coming back to him. After Aoshika's release from her chains, Haguro tries to kill her, telling her that Inugami is too good for her. Inugami shows up in time to beat him up. During their fight, Haguro slices off two of Inugami's fingers and eats them in an insane attempt to confirm himself as a superior beast to Inugami. Then Haguro slices off four more of Inugami's fingers - and an entire arm. In addition to all this Haguro also commits the SECOND school shooting of the series with an MGL-140, a semi-automatic grenade launcher. The attack hospitalizes Aoshika, who still survives to later identify him as the shooter.
Handsome, charming Dr. Kazutaka Muraki from Yami No Matsuei. As of the start of the series, he's already spent several years systematically kidnapping, dismembering, and vivisecting small children (like Innocent Flower Girl Eileen, whose heart he harvests for her friend, Tsubaki, raping adolescents and infecting them with slow, agonizing fatal diseases (like Hisoka), and seemingly murdering pretty much every grown woman he comes across, whether to use them in scientific experiments to attract the attention of the Shinigami or just for lulz. All of this murder, torture, and rape is really only the means he uses to the end of fashioning a good old Mind Rape, whether it's mentally torturing a girl madly in love with him into developing split personalities (like the aforementioned Tsubaki), mind-controlling suicidally depressed pop stars into becoming blood-drinking monsters (like Maria Wong), or stalking and harassing one of the Shinigami ( Tsuzuki) with so much misdirected guilt that he finally manages to drive him into a catatonic state, in which state he fully intended to vivisect the guy and use his powers to bring his older brother Saki (apparently another CM) back to life, so that he could kill him more slowly and painfully for the murder of their parents.
Metroid's Ridley, in the manga adaptation, is the series version of evil incarnate. His first encounter with Samus has him landing on Samus' home of K2-L, and telling his minions to "First enjoy the slaughter to the fullest!" Not long after killing most of the planet's workers, he tries to kill the three-old-Samus, but her mother saves her. He later eats her parent's bodies after Rodney Aran destroys his ship and badly wounds the giant space dragon. This comes up later when Ridley uses this fact to send Samus into a Heroic BSOD.
Ghost in the Shell: Stand Alone Complex has Kazundo Gohda, director of the Cabinet Intelligence Service. A charmless, callous, and totally amoral Manipulative Bastard, Gohda's (largely self-inflicted) Inferiority Superiority Complex and obsession with Great Man theory led him to kill hundreds with the terrorist-producing Individual Eleven virus, to come within inches of starting a genocidal war, and to try to nuke a crowded city-state half a mile off the coast of Japan just to show that he could. To give some impression of how severely he eclipses the other villains of the series in heinousness, one of his most minor crimes was to deliberately expose labourers to a dangerous work environment (he asked them to excavate a buried ruin, but didn't tell them it was a heavily-irradiated nuclear facility), and then cover it up with a string of murders. Someone else did something similar on much the same scale elsewhere in the series, and it became the driving force of most of the first season.
Jinki Extend's Kalis Norman in both the anime and manga continuities.
In the anime, Kalis manages to establish himself as one of these in less than ten minutes screentime, completely altering the tone of an otherwise tame and derivative show with his very presence. Disguising himself as thirteen year old Satsuki's older brother, he gets close to her, slashes her with his scythe, brutalises her, and then rapes her, ranting the entire time about how she should "be good for her big brother". When the rest of the Angel team arrive, Kalis tries to escape, taking Satsuki with him, and gloating about how he's going to continue "loving her like a brother". When Akao attempts to stop him, Kalis tries to kill her with one hand, while continuing to grope Satsuki with the other throughout the fight, snickering about how easy it was to do this to her. His actions leave Satsuki completely shattered, and of all the people in Shiva's employ he's easily the most despicable.
Kalis is even worse in the manga, where he's essentially a RapistFor Hire. Employed by de factoBig BadShiva for the purpose of breaking potential Angel pilots, Kalis assaults and rapes one of the main girls, driving her into a Heroic BSOD. When she refuses to scream for him, Kalis has a minor Freak Out ("You boring bitch, you won't even scream!") and starts cutting her up with his scythe; when the rest of Angel team interferes, he tries to kill them all. Reappearing at the end of the volume, Kalis ambushes Satsuki and tries to rape her as well, only to be halted by the male lead. Returning again in volume three, Kalis tries to apply his craft to the entire Angel team, via a giant, fluid spraying, tentacle rape machine. A raving misogynist, who gets off on the psychological damage he inflicts as much as the actual rape, and thoroughly warps the tone of the story with every appearance, Kalis is never less than absolutely disgusting.
Sadist Teacher Shidou of Highschool of the Dead first shows he's a man to fear when, during a zombie attack, he kicks a helpless student who tries to beg for help, gloating over the poor kid's impending death and his own survival. Upon becoming the leader of a schoolbus of kids, Shidou sets out to make himself a cult leader, promoting sexual activity amongst the kids to make them loyal to Shidou. When one student doesn't participate and expresses worry over his family, Shidou has him thrown off the bus for the zombies. In a Zombie Apocalypse, Shidou stands out as more evil and vile than any walking corpse.
