  • 30 Days of Night: Immortal Remains:
    • Bork Dela is a vicious, vampiric Serial Killer dubbed "the Headsman", who goes on a killing spree in Savannah, Georgia. He kills men and women alike—often in their own homes—leaving behind very little if any blood behind in the process, and always beheading his victims. While investigating the series of murders, Dane discovers a woman whom Dela had raped. It's revealed that prior to his turning, Dela was said to have been the one who introduced Hitler to the occult, and may have had a hand in his death. He had also been Vicente's bodyguard before Eben killed him. When Dane confronts him, he calls Dela out for his Fantastic Racism, and Dela retorts that Dane's sympathies for humans are like celebrating having once been apes. Later in the book, it's revealed that he has been supplying the rogue vampire Elder Enok, with blood. Ax-Crazy and bloodthirsty even by vampire standards, he cares nothing for the Masquerade enforced by the Elders, and his evil deeds cannot be even remotely justified by Transhuman Treachery or a need to survive.
    • Introduced towards the end of the same book, the aforementioned Enok is a dreaded rogue Elder who turned both Vicente and Lilith—whom is shown to be still very-much "alive", yet dismembered and incapacitated, and in Enok's captivity—thus being somewhat responsible for both the destruction of Barrow and the slaughter in Los Angeles, respectively. He dwells in a human slaughterhouse where people are rounded up, shot in the head, and their blood is drained into buckets to be fed upon like free samples, and plans to overthrow humans as the dominant species and reduce them to cattle, presumably to be farmed for their blood and slain in slaughterhouses like this across the globe. When Dane and Eben confront him, he sentences Dane, whom he considers a Category Traitor, to be killed by a horde of ravenous vampires while he tries to fight Eben—a Worthy Opponent in his eyes, to contrast with Dane—into submission, or kill him if he refuses. Malevolent and horrifically ambitious, Enok is by far—at least prior to Eben's Face–Heel Turn in the comic—the most terrible vampire in the series, Elder or not.
  • 1901, by Robert Conroy: Kaiser Wilhelm II, the inept-yet-lethal ruler of Imperial Germany, envies the British Empire's prestige.

During the course of the war, the Kaiser orders German immigrants to America killed in mass executions, denouncing them as traitors; has New York City occupied and looted; destroys several important landmarks and has thousands of foreign vessels forcibly commandeered to help supply his army. Posing the demeanor of a sulking child, Kaiser Wilhelm II was so consumed by his insecurities he would risk anything, even war, to alleviate them.
  • Abarat: Mater Motley (successfully) brings about the end of all that is good by making a pact with beings whose whole purpose is to destroy. She releases untold millions of evil insects, and then burns the world with a massive deathship. She burned down her own house rendering her son blind and killing all but one of her 20 or so grandchildren. It turns out all of these acts were just For the Evulz and she's just that horrific of a person. Her abuse of Christopher Carrion for all his life, such as sewing his lips shut for mentioning the word love, is what turned him into a Woobie, Destroyer of Worlds.
  • Act of Love, by Joe R. Lansdale: The Houston Hacker, real name Phillip Barlowe is a depraved necrophiliac and cannibalistic serial killer who begins murdering young women in Houston, taking parts of them to cannibalize as well. After three such deaths, the Hacker is enraged the cops are hunting him and targets the hero Marv Hanson's teenage daughter, running her off the road and killing her boyfriend. He proceeds to use his civilian guise to convince Hanson his partner Joe Clarke is the Hacker, but does the same to Clarke as well, while murdering a reporter who got too close to the truth. along with the reporter's family. When Hanson is distracted, the Hacker takes the opportunity to attack Hanson's home, killing Clarke and the other cops there before planning to rape and kill Hanson's wife after he attempts to crucify her to the wall.
  • The Acts of Caine: Berne distinguishes himself from other assassins, like Caine, by being a stone cold psychopath, torturer and rapist. We first see his insanity manifest when he kills a nonhuman prostitute for absolutely no reason, and he relentlessly hounds Caine and his allies with murder on his mind. Berne kills any of Caine's allies that he can and, at one point, tries to rape a captive man as an interrogation tactic. At the end of the day, Berne's only goal is to kill whom he can and get away with it. He especially wants a fight with Caine to satisfy his bloodlust.
  • The Adversary Cycle: Rasalom is an ancient Evil Sorcerer who embraced a role as the champion of darkness in forgotten eons. Defeated by his Arch-Enemy Glaeken, Rasalom was sealed into an old keep in Europe until World War II. Posing as a vampire, Rasalom convinced a Jewish teacher to aid him in guise of being a Noble Demon fighting the Nazis. To gain power, Rasalom murdered the German soldiers and revived them as enslaved undead until Glaeken returns to destroy him. Surviving by binding his soul to an unborn baby decades later, Rasalom emerges to take the world itself: plunging the world into eternal night before driving human beings to insanity and murder while unleashing monsters that kill indiscriminately on the populace. Rasalom only spares the now elderly Glaeken's apartment solely because he wants Glaeken to see the world he loved burn before Rasalom kills him slow. He's also angry one of the humans nearly accidentally caused his host-mother to miscarry and plans a similar fate for him. Even in the dark world of the Repairman Jack and Adversary Cycle books, Rasalom stands unique as the greatest monster the saga has to offer.
  • Aeon 14: Stavros, from the Rika's Marauders novel Rika Redeemed, is the dictator of a relatively small empire in the Praesepe Cluster called the Politica. He drove the Oranians off their homeworld onto another location deeper in the system, turning their home in exile into a Vichy Earth in direct imitation of the ancient Romans and Nazis, something he says he's done elsewhere. He has also technologically and psychologically enslaved almost his entire military, including many combat cyborgs known as "mechs". In the book proper, when Silva, the mother of his heir by a one-night stand who was later turned into a mech, attempted to retrieve her daughter Amy, whom he beats, he captured her and enslaved her as Amy's bodyguard/pet, using her compliance chip to force her never to reveal that she is Amy's mother while encouraging Amy to address her as "Meat", a Fantastic Slur for mechs. When Rika, Silva's former subordinate, goes undercover in The Politica as a defector from her mercenary company, Stavros insists on installing a compliance chip in her as well. Rika is immune, but in order to maintain her cover is forced to play along with Stavros using the chip to make her perform a sexual act on him. Leslie, one of Rika's teammates, is captured during the mission and chipped as well. When Rika finally initiates the plan to liberate the mechs and kill Stavros, he resorts to using his own daughter Amy as a Human Shield. While other villains in the franchise have significantly higher body counts, few approach Stavros for sheer personal vileness.
  • After Midnight, by Richard Laymon: Steve, a Serial Rapist and Serial Killer, travels the US with his ally Milo, the two raping and killing as they go. Tiring of Milo always taking "first dibs" on the women, Steve sets him up to be killed by the novel's heroine Alice, and decides upon her as his next victim.

  • Alex Cross has faced many revolting criminals, but these stand out as the worst:
    • Kyle Craig, or The Mastermind, is a former FBI special agent and Alex Cross's Arch-Enemy. A violent individual since childhood, Kyle was responsible for multiple killings even before joining the FBI, including that of his own brother. As the Mastermind, Kyle perpetrates a series of bank robberies followed by murders in Roses Are Red, making sure to dispose of his accomplices, and raping the women he had hired post-mortem. While his partners at the FBI are busy investigating the murderous robbers, Kyle rapes and kills a woman in a home invasion, and then sets his eyes on Alex's girlfriend, committing the same crime with her and mutilating the body afterwards. Kyle calls Alex to inform him about the horrendous death of his girlfriend, just so he could hear his reaction. Realizing in Violets Are Blue that he has been exposed, Kyle attempts to kill Alex's partner and later a woman he had saved from another killer, but is arrested and sent to death row. Assuming the identity of his attorney in Double Cross, Kyle escapes and kills his mother, using her money to travel around the world and murder more people, including the judge who had sentenced him to death. Failing to kill Alex, Kyle returns years later in Cross Fire, this time posing as a FBI agent he had killed who had been assigned to work with Alex. Seeking to hurt Alex's loved ones, Kyle attempts to take his family hostage, and commits suicide upon defeat, dying in confusion to why Alex did not kill him. A merciless Serial Killer with an obsession for female bodies and being Alex's shadow, Kyle was one of the worst criminals Alex had to face in his career.
    • Gary Soneji, real name Gary Murphy, is one of Alex Cross's earliest and most personal foes. First appearing in Along Came a Spider, Soneji is a depraved killer who claims to have killed over 200 people, and starts the book by brutally murdering two black families, mutilating the women and even killing an infant. Longing to become the most infamous criminal mastermind in modern history, Soneji duplicates the Lindbergh baby case by abducting two private school children, fully intending on burying them alive while he disappears without a trace. Killing the FBI agent in charge of the case as well as a schoolteacher, Soneji has a breakdown after his plan goes awry, and takes a McDonald's restaurant hostage, killing an innocent man and a cop. Upon his capture, Soneji quickly plans his escape, and once he's free he attempts to murder Alex Cross's family for revenge. Returning once again in Cat and Mouse, Soneji, feeling he has nothing to lose due to contracting AIDS in prison, decides that the whole world deserves to be punished for his misfortunes, and goes on a cross-country killing spree, slaughtering innocent men, women, children, cops, and even his own wife; he leaves his young daughter alive, but tied up in his house's cellar to slowly die of starvation. When confronted by Cross yet again, Soneji takes a bus full of innocent people hostage with a bomb, and abducts a baby to ward off the cops before attempting to beat Cross to death for "ruining his life". A relentless and utterly unstable murderer who longs to top other killers in sheer brutality, Gary Soneji would stop at no limits to feed his pathological need for attention.
    • Geoffrey Shafer, known by law enforcement as the Weasel, is one of Cross's most personal enemies. A diplomatic staff member moonlighting as a Serial Killer, Shafer is playing a "game" with a few other men that he meet at the MI-6, who style themselves after The Four Horsemen of the Apocalypse, with Shafer playing the role of Death. He is introduced in Pop Goes the Weasel, when he finds a prostitute and brutally kills her. He then puts on blackface, goes out in a cab, picks up a woman and murders her. He later goes out again, finds a man, and kills him too. Shafer stalks George Bayer, who plays Famine in the "game", murders the women he solicited, and leaves the bodies in a compromising position. Realizing the police are on to him he goes south to Maryland and kills a mother and her teenage daughter. Shafer then targets DC Detective and Cross's love interest Patsy Hampton and brutally kills her. Cross arrests him, but evidence being inadmissible due to diplomatic immunity means he gets acquitted. Shafer then kidnaps Cross's fiancée Christine. He murders the other players of the "game". After a fight with Cross he apparently dies, but resurfaces in Europe and kill his wife. He reappears in London Bridges living in Brazil. Here he continues his murderous hobbies until The Wolf uses a streetwalker to draw him out, kidnap him, and get Shafer to work for him. Shafer bombs an army base, and then meets a sniper and has her kill the CIA Director. He later goes out and kill another prostitute. After that he goes and confronts his sister-in-law and children. He threatens them, asks them for a kiss, and when they refuse he only refrains from killing them because he states that he "does not have permission" to kill them.
    • Cross Country: Abidemi "The Tiger" Sowande is a nihilistic African warlord driven by his own amoral belief in committing atrocities For the Evulz. The leader of a large group of savage Child Soldiers, and an attack dog for corrupt members of the CIA, Tiger grabs Alex's attention by dismembering his ex-girlfriend and her entire family, children included. Having perpetrated countless gut-wrenching crimes with his minions, Tiger rapes and murders Alex's friend in front of him, but not before massacring her entire family for fun.
  • Alex Rider:
    • Scorpia: Julia Rothman is a executive board member of SCORPIA, who plans to make outrageous demands to Britain that will never be met, kill a high school of children when they are not met, and make the same demand to America with the same consequence knowing that they will meet them, and ultimately cause a war to erupt between the two countries. To demonstrate the weapon and show that she is not bluffing; she kills a completely separate group of high school football players without giving them a chance to be saved. She also manipulates Alex into joining Scorpia by getting him to think his father worked for them and was killed by MI-6 when it was the other way around. She was planning to betray and kill Alex in the end. In the Prequel Russian Roulette she executes an assassin for failure.
    • Snakehead: Major Winston Yu is another board member, as well as the leader of a ruthless Snakehead gang. He takes part in SCORPIA's plans to kill the members of a conference against poverty. His plan involves causing a tsunami and kill millions of people to make the deaths look like an accident, overshadow the deaths of the conference members with the deaths of millions, and to drum up sales for his Snakehead gang. When Yu captures Alex, he decides to have him slowly killed on a hospital bed as he removes his organs one by one; one organ a day until all that is left of him is a husk. This seems to be his preferred method of execution, since he has people killed in the same hospital, in the same way on a regular basis. Yu is so bad that his henchmen commit suicide before he can punish them for failure.
    • Scorpia Rising: Abdul-Aziz Al-Rahim, better known as just Razim, is another agent of SCORPIA, and is affiliated with them purely to slake his sadistic curiosities. A cold, unfeeling sociopath since his history of violence in his youth, Razim sold out his own parents and sister to Saddam Hussein before joining SCORPIA. Come his involvement in Operation Horseman, Razim plans to blackmail Britain into handing over the Elgin Marbles, or else defame the country by revealing the contents of the Horseman file, ultimately to assassinate the Prime Minister of England and throw the country into a war. Fascinated by pain, Razim routinely tortures countless innocents to death in perverse "experiments", in an attempt to create a measurement for pain, initially claiming it for the sake of science but likely simply to amuse himself more than anything. When Razim captures Alex, Razim forces him to watch his mentor and guardian Jack Starbright blown up—in truth handing her off to the Grimaldi twins but keeping the emotional stab to Alex all the same, while casually adding the boy's emotional pain was so great, he may have to create a second measurement. From there on, Razim tries to have the US Secretary of State assassinated, framing Alex so that he'll be shot dead. Lacking the scale of previous antagonists but trumping all of them in sheer, frightening sadism, Razim makes his mark even in the dark world of Alex Rider as Alex's most personal foe.
  • Alex Van Helsing series, by Jason Henderson: The Icemaker, true identity Lord Byron, is a vicious vampire clan lord, and is bad even by their standards. Formerly a narcissistic poet who abused his lover Claire Clairmont and abandoned their young daughter Allegra to die, Byron became a high-ranking member of the vampire organization, the Scholomance, and seeks to bring about humanity's downfall and allow the undead to claim the earth. Noted for his excessive bloodlust and slaughtering entire communities, the Icemaker's ultimate ambition is to revive Claire to rule as his queen, motivated primarily by obsession rather than true love. It is later revealed that the psychopathic vampire Elle is his daughter, and that Icemaker had her kidnapped from her foster father Polidori and converted into a vampire, traumatizing her so much that she repressed all memories of her childhood. When this is revealed to Elle, Icemaker immediately abandons her once more, leaving her a broken wreck.
  • Alex Verus:
    • Vitus Aubuchon, an old mage and the heir of the Aubuchon family, has survived centuries by using dark magic to harvest the blood of victims to preserve his own life. Vitus has preyed primarily on children, abducting them into his ancestral home and cutting their throats to get to their blood before storing their bones like trophies. In the present, Vitus has realized the magic is no longer working for him as it once did, and instead switches to abducting magic apprentices for their blood with one such disappearance prompting the attention of Alex and his friends. When they make their way into Vitus's home, Vitus promptly attempts to slaughter everyone inside.

Others who resemble celebrities are physically altered and then mentally forced to service any fantasy of the client. Vihaela also runs the brothels on a "points" system, with whoever fails a task or displeases a client obtaining a point. At the end of the month, the one with the most points is sent to Vihaela's laboratory and never returns. Upon being discovered, Vihaela promptly betrays her associates and sacrifices an innocent woman made to look like her in order to escape.
  • The Algebraist, by Iain Banks: The Archimandrite Luseferous is a gleeful sadist with a love for hurting others and lust to be feared and hated above all else. Having risen through the ranks of the military after sentencing his own father to death, Luseferous founded the "Starveling Cult", a militaristic group of barbarians who Rape, Pillage, and Burn entire planets at their leisure, all as part of Luseferous's quest for galactic domination. In his downtime, Luseferous enjoys perfecting styles of torture, such as keeping one of his foes' heads around as a sentient punching bag, killing an assassin by making his teeth grow until they pierce his brain, and raping entire harems of women, taking sick pleasure from their utter loathing of him. While invading the Ulubis system, Luseferous displays his utter joy over a huge body count by first blowing up an entire city, then later destroying the life supports systems of a Habitat, leading 80,000 people to be sucked into the vacuum of space. Once arriving at Ulubis's capital planet, Luseferous first reveals that, for every second it doesn't surrender, he will fire a man, woman, or even child prisoner of his into space to die, then follows it up by unveiling hundreds of Ulubis children he kidnapped from a field trip, promising to start executing them randomly until he gets what he wants. When reinforcements arrive to drive Luseferous away, he orders all the children slaughtered and the remaining 20,000 prisoners dumped into space, before attempting to flee the entire war effort, leaving behind orders to firebomb billions of innocents just as a last spiteful move. Luseferous was an irredeemable beast, with nary a likable or sympathetic quality about him, just horrific cruelty.
  • Altered Carbon: Reileen Kawahawa is a "Methuselah", or "Meth"—a long-living human in an age when people can achieve mental immortality through the storing of their memories. Starting her career as a young gang member in Fission City who forced people to drink contaminated water or see their families tortured, Kawahara eventually rose to the top by torture and murder. Running a virtual prostitution ring, Kawahawa has people indulge their sick fantasies before allowing them to do the same to a living woman, making certain they are women who will die permanently. When one of her fellow Meths, wealthy businessman Laurens Bancroft, refuses to assist her, Kawahara has him drugged so he will murder the next prostitute he's with to put him under Kawahara's thumb. To force the hero, Takeshi Kovacs, to assist her in framing a former associate of hers for the crime, Kawahara threatens to put Kovacs's girlfriend into virtual torture and later decides to try to do the same to Kovacs himself for all eternity.
  • American Psycho: Patrick Bateman is a despicable and narcissistic psychopath who moonlights as a horrific mass murderer while keeping up his public image as a stock broker. Bateman's career of torture and murder having started for no discernible reason, his most frequent act of depravity is luring women to his apartment, then brutally raping and butchering them in the most horrifying ways he can imagine. Be it nailing them to the floor, lopping their heads off, or bisecting them with a chainsaw, Bateman indulges in every act of sick cruelty he can muster, and even delves into cannibalizing his victims. Bateman's evil is so petty and unpredictable that he disembowels vagrants after giving them pep talks, takes an axe to one of his associates for, among other slights, having a better business card than him, and tortures defenseless animals. One of his crowning moments of vileness comes when Bateman slashes a child's throat, then pretends to be a doctor trying to save him, just to see how it feels, quickly deciding it isn't as fulfilling as killing someone who has lived a full life and thus loses more when he ends them. After going on a slaughter spree throughout his city, gunning down everyone he sees, Bateman comes to the conclusion that he is completely and totally wicked with no capability of care or compassion for others. Though the idea that some of his crimes were imagined by him is implied, Bateman's character is nevertheless pure evil. Driven by his sadism and pathological desire to be important, Patrick Bateman fully earns the various terms he is referred to as: an inhuman, a ghoul, and a monster.
  • Angelmaker: Shem Shem Tsiem, or the Opium Khan, was born a Prince during the twentieth century and quickly moved to have all his family members he could hunt down with a claim to the thrown drugged and burned alive. Choking his surviving nephew to death to seal his claim to the kingdom, Shem Shem Tsiem commits so many atrocities against his people that they flee in terror to the surrounding woods, and forcibly focuses all agricultural production on producing opium to avariciously conquer the world market. To stroke his own ego, Shem Shem Tsiem tortures an archbishop into insanity, leaving him reduced to a barking animal to proclaim his divinity. To spite his own mother and her love of elephants, Shem Shem Tsiem sadistically creates a worldwide poaching ring to have them killed for sport, much to her torment, later cutting out her tongue and decapitating her to put her head on a spike. Under the alias "Brother Sheamus", Shem Shem Tsiem takes over Edie Bannister's former organization, the Ruskinites, and savagely corrupts them, creating minions by brainwashing and destroying the minds of countless people, including young orphans. Ultimately dreaming of turning the whole world into a mass of lobotomized, obedient slaves and extensions of himself, Shem Shem Tsiem uploads his mind into Vaughn Parry to live forever as an unquestioned God. Facing off against Edie in present day, Shem Shem Tsiem has her ally, Joe Spork, sent to an asylum in the hopes of breaking him for information and than turning him one of his mindless minions. An utter monster embodying the most narcissistic of god complexes, Shem Shem Tsiem cements his position as Edie's Arch-Enemy.
  • Animal Farm: Napoleon, the Big Bad of this Beast Fable on the Russian Revolution, represents Josef Stalin. While he seems like a benevolent revolutionist at first, who tries to make Old Major's dream a reality, it quickly becomes clear that he is just a selfish, power-hungry tyrant, who cares not one bit about his fellow animals. He starts by rationing food exclusively for him and the other pigs. He also secretly forms his own private squadron of attack dogs, by abducting all the newborn puppies from their parents and raising them to be fully obedient to him. Later he backstabs his ally Snowball—explicitly having the dogs kill him in the 1954 Animated Adaptation—and frames him for every wrong happening on the farm, while continuing to manipulate everyone into worshiping him and mercilessly sentencing everyone to death who shows the tiniest sign of resistance. He truly hits the Moral Event Horizon when he sells the completely loyal and by far hardest-working horse Boxer to the knacker after he got sick, in order to buy himself more alcohol. He justifies his actions by having Squealer constantly alter the law, and the past, to fit them. After a few years and a whole lot of more horrendous crimes, the other animals can barely tell him and the other pigs apart from the humans, whose reign they so desperately tried to escape.
  • Animorphs: In a series full of shades of grey and with a theme of War Is Hell, a select few stand out as truly monstrous and evil individuals.
    • Esplin 9466 (the greater), better known to the cast as Visser Three. The only Andalite-Controller in existence, Visser Three is the sole Yeerk with the power to morph. In his first appearance in the series, he morphs into a horrific monster and eats Prince Elfangor alive, firmly establishing his characterisation for the rest of the series. A low-functioning sociopath with a Hair-Trigger Temper, Visser Three takes every opportunity he can to kill people, by personally decapitating his subordinates and their hosts left, right, and centre. He repeatedly eats those he dislikes, and outrages other Yeerks when he morphs a Yeerkbane, one of their few natural predators, and uses it to devour subordinates who have failed him. As the commander of the invasion of Earth, Visser Three cares nothing for casualties and is willing to write off thousands of his own Yeerks rather than negotiate. He is the worst boss in the series, and no matter how awful things got, always gave the Animorphs the most nightmares.
    • Crayak is an alien and member of The Highest Powers who acts as the series' God of Evil. A nearly omnipotent Social Darwinist, Crayak seeks to create a universe ruled by one species and one species alone. To that end, Crayak engineered the Howlers, a race of psychopathic child soldiers who think that killing is a game, and used them to gruesomely exterminate countless species, including the pacifistic Pemalites and Graffen's Children. In order to ensure that the Howlers' Hive Mind is never contaminated by memories of defeat, Crayak obliterates any Howlers who fail him; he also destroys any Howlers who realise that their victims are people too. Not content with having created one of the most feared races in the galaxy, Crayak also lends his godlike might to other vicious species, secretly backing the Yeerks and other would-be galactic conquerors; he plans, for example, to have the Yeerks enslave humanity, only to then be wiped out by the Howlers. In a series filled with shades of grey, Crayak was as close to pure, unadulterated evil as one was likely to get.
    • Subvisser Fifty-one, also known by her host's name, "Taylor", is a cruel Yeerk. Infesting the mentally ill girl, Taylor becomes an angry monster who serves as Visser Three's Torture Technician. Using a device that tampers with the pain and pleasure centers of the brain, Taylor captures Tobias and makes him relive the worst moments of his life and inserts agony to the recollections of his best memories. Returning months later after Tobias is rescued, Taylor reveals she severed her mental link with her host, regaining her sanity but not an ounce of morality. Taylor manipulates the Animorphs into helping her kill Visser Three, taunting Tobias about the suffering she put him through, hoping to provoking him into attacking her so she has an excuse to hurt him more. Revealing that her actual plan is to kill thousands of her fellow Yeerks, Taylor intends to pin the blame of her attack on the Yeerk Peace Faction.

As Cas and his friends fight him, Anna pulls off a Heroic Sacrifice by opening a portal to Hell and dragging the Obeahman down with her. A year later, Cas discovers that, while both are in hell, the Obeahman has been torturing Anna the whole time. When Cas and another girl, Jestine, make their way to a part of Hell, they find that the Obeahman had transformed into a spider-like creature that had linked Anna to it, sewing Anna's eyes and mouth shut before harvesting her.

  • Armageddon Force: Dr. Edgar Malbarn, an utterly psychotic sadist, runs the Carvina Cooperation, an organization which takes wounded soldiers off of battlefields and conducts fiendish, torturous experiments on them. Malbarn, using only enough anesthesia to prevent Carvina victim Jon Heck from passing out, replaces Jon's blown-off arms with mechanical ones. Much to Jon's disgust, Malbarn plans to make Jon head of Malbarn's brainwashed army, which will spread chaos throughout the world. All the while, Malbarn taunts Jon, and lashes out when he gets angry, torturing him even beyond the experiments. Once Jon is rescued, both he and fellow Carvina victim Yui Shinozaki are haunted by nightmares of Malbarn, which continue even after Jon kills Malbarn.

    • Opal Koboi is a genius pixie who desires to become "empress of the world". Opal before the series became head of her father's company by driving him insane and having him and her mother locked in an insane asylum. Organizing the Goblin rebellion alongside Briar Cudgeon, Opal took advantage of their violent nature to cause an uprising, while all along planning to betray them. To escape prison after being arrested, Opal creates a clone, not caring it will die easily and cannot think for itself, allowing her to manipulate it. Killing Holly's mentor, Julius Root, by having a bomb strapped to him and then cruelly tricking Holly into detonating it, Opal then frames her for it and Mind Rapes a kind-hearted humanitarian, forcing him to send a probe into the Earth and reveal the Faerie people, hoping to cause a war behind humans and Faeries. Opal is also revealed to have experimented on and killed endangered animals to make herself more powerful. In the final book, Opal murders her own past version of herself when the past version of her was trying to free the present Opal from prison, which causes all products produced by her company to explode, with planes crashing and global communications cutting off. Finally, Opal manipulates the ghosts of dead Faeries to Kill All Humans and take over the surface world. A thoroughly childish woman dedicated to getting whatever she wants regardless of innocent lives lost, Opal is Artemis's greatest and most evil enemy.
    • Lost Colony: The demon Leon Abbot, real name N'Zall, was a bellicose proponent of their war with mankind even when it meant certain extinction for their race. Sabotaging a ritual by the demonic warlocks to save their people to kill them, Abbot returns to the demons, pretending to be a savior while brainwashing the masses into thinking they were resuming their war with humanity, with Abbot instead using it as a ruse to keep them under his control. Savagely torturing any who show opposition to his power, Abbot remains apathetic even when Artemis and his allies reveal that Abbot's methods will lead to the destruction of his dimension. Causing the extinction of his people before time is reversed, Abbot again tries to kill the heroes even after being brought back to life, endlessly bitter and power-hungry.
  • The Ascendant Kingdoms Saga: Thrane, aka Hemlock—"like the poison"—is a vicious vampire warlord whose body count exceeds the other villains. One of the oldest of his kind in the world, Thrane was a barbarian warrior in life and never outgrew that attitude in undeath; he believes that vampires, being stronger than humans, have the right to rule over them, and that Thrane himself should rule the vampires. In a setting where many vampires try to live in some degree of harmony with the living, Thrane openly flouts such ideas by keeping pens of human slaves he feeds on like livestock, and even "favored" mortal minions get treated like dirt at his whim. Vampires who disagree with him are treated no better; at one point Thrane casually decapitates a potentially ally for daring to ask what benefit he might get from their alliance. Adding to his crimes, many characters believe that Thrane was responsible for the Great Fire, a catastrophe near the beginning of the series that destroyed most magic and caused the near-total collapse of civilization on at least three continents, and in the aftermath he further provoked the chaos by backing various brutal warlords; all in the name of tearing down human rule to place vampires on top, and himself as ruler of vampires. In the end, the other vampire elders and human heroes unearth a forbidden weapon capable of slaying a vampire elder and all his brood for the sole purpose of putting Thrane down for good.

    • Reginald Birch is also the Greater-Scope Villain of the Kenway Saga. Initially a friend to Edward Kenway, when the latter's daughter, Jennifer Scott, exposes Birch to her father as not only a Templar of the British Rite but also their Grand Master, he sends mercenaries to the Kenway manor to murder Edward Kenway, and kidnap Jennifer to be sold as a Sex Slave to Turkish slavers, all while framing a innocent servant for the crime. He then takes in Edward's son Haytham, only so he could manipulate him into becoming a killer as well as a Knight Templar fanatic. From there he has Haytham kill many people, including the opposing Assassins. He even has a fellow Templar tortured and castrated when he got in the way of his plans. He also has Haytham uncover technology from the First Civilization, knowing full well the kind of destruction that they bring, all so he could use them to rule the world, even sending the below-mentioned Edward Braddock to help him. When Haytham finds where Jennifer is being captive as well as Birch being the true culprit behind his father's murder, Birch tries to have Haytham killed along with Jennifer.

When Birch assigns him and Haytham to various parts of the world to uncover First Civilization technology, the former only questions Reginald's obsession when it meant his own life and position might be at stake; it doesn't detract from his cruelty during their search, as he continued to kill numerous people, not just his enemies, but also his allies and the innocent, much to Haytham's shock. During the Seven Years' War, Braddock oversees the annihilation of many French camps, and when one of them tries to offer a truce, he ignores it has order his men to kill them all, causing needless deaths on both sides of the field.

That said, there are two characters, brother and sister Evil Sorcerers, whom everyone else agrees are completely evil:
    • Arunis is an immortal, sociopathic, manipulative sorcerer who set most of the immediate plot (including the coming world war between superpower empires and the retrieval of an extremely dangerous Artifact of Doom) in motion to further his own ends. Those ends turn out to be arranging the destruction of the world as an offering to the Night Gods, so that they will be impressed enough to elevate him to godhood himself. In pursuit of this goal, he kills, tortures, and Mind Rapes his way across two continents, including sacrificing his own (few) loyal minions for short-term advantage, all without the slightest whiff of remorse. His in-universe reputation is well earned. He even manages to make trouble post-mortem, with his ghost mind raping one man to the point of destroying his personality while trying to possess him. Guy was an Asshole Victim, but still.
    • Macadra is Arunis's rival, on-and-off co-conspirator, his peer in age, power, and wickedness, and his sister. She wants the same Artifact of Doom he does, though she intends to conquer the world rather than destroy it. Her handiwork is mostly plainly visible in the fate of the Empire of Bali Adro, whose throne she subverted centuries ago, in the process turning it from a prosperous, enlightened society to a totalitarian hellhole (much to the horror of the time-displaced Bali Adrans traveling with the protagonists). Like her brother, she's The Dreaded and a Bad Boss, and she drives her soldiers so hard in pursuit of the heroes across the last book that they end up deserting in droves as soon as they have the opportunity.

  • Chronicles of the Kencyrath: Gerridon, in the distant backstory, was the greatest leader of the people, Highlord of the Kencyrath and Master of Knorth, but he would go down in history as their greatest traitor. Desiring immortality—in a Martyrdom Culture—and bitter that the absent Three-Faced God wouldn't grant it to him, he sold the souls of his race to their ancient enemy, Perimal Darkling, in exchange for eternal life and manipulated his twin sister Jamethiel Dream-Weaver into reaping them for him. This betrayal would not only destroy two-thirds of the Kencyrath, but leave scars in their collective psyche that would linger for millennia. When Gerridon's immortality began to fail him he sought out various means of sustaining it, including attempting to create a child of his or Jamethiel's blood to take over as Dream-Weaver—by rape if necessary—and taking command of an ancient religious sect and whipping them into a fanatical fervor in which they brutally tortured hundreds of Kencyr prisoners of war, including Gerridon's own nephew, in an attempt to force them to convert.

In addition to being willing accomplices in all of Foul's crimes note , and sharing his gleeful, psychotic sadism, each Raver has racked up a number of atrocities of his own. Moksha Jehannum Fleshharrower and Samadhi Sheol Satansfist both did stints as Foul's head general, massacring countless innocents—and their own troops. Individually, Samadhi, as Gibbon na'Mhoram, was the head of a Path of Inspiration that sacrificed countless lives while lying to the people of the Land that it would help reverse the After the End conditions of the Sunbane, when in fact it was just making it worse; Moksha stalked Covenant over much of the Second Chronicles infecting him with venom in order to force him to use his ring at full power whether he wanted to or not, which would have destroyed the world, which was the plan. Turiya Herem Kinslaughterer doesn't show up as often as his brothers, but commits one of the single most appalling atrocities in the Chronicles: single-handedly committing genocide of the Giants of Seareach while they refused to fight back.

A fanatical fundamentalist, we first see Joseph's evil when he beats and whips David for an innocent childhood remark about needing a third hand. He then brutally whips David to get him to give up the location of his friend Sophie Wender so he can sterilize her. Upon Sophie's capture, he proceeds to smugly gloat about it in front of David, who is only 10 years old, just to hurt him. When it is discovered that David and his little sister Petra are telepathic, and therefore blasphemies, he personally leads a posse to kill his own children and torture them, even though he had previously tried to spoil Petra. A horrible fundamentalist who unnerves even the Inspector, whose job is to deal with blasphemies, Joseph represents the worst of human intolerance, seeing purity as more important than even his own children.
  • Chung Kuo:

In a bid to assert his dominance over Isana, he forces her to watch his men gang rape Odianna. When that doesn't work, he reveals his preferred method of breaking slaves: the discipline collar. These devices force slaves to feel intense pleasure or agonizing pain based on whether or not they obey their masters. After showing off the collar on Odianna, he tells Isana that the next night he'll rape Odianna, using the collar to make her like it, then do the same to Isana.

His plan was that if he died, the volcano would erupt and kill millions upon millions of people within the region. Unable to disarm the fury, Gaius Sextus is forced to set it off to minimize the damage, killing everyone within Kalarus's realm.
    • Invidia Aquitaine is a Machiavellian plotter that desires to obtain as much power as she possibly can.

Brought to trial by the vampire council for turning humans, Lucien manipulates Gavriel into taking the fall for him, nearly leading to his death, had the Spider not chosen to spare the latter, instead appointing him to destroy new vampires to stop their kind from spreading.

Slaughtering thousands across countless worlds and keeping their souls bonded for all time in its amulet, Trell sets its sights on Earth by slaughtering the vast majority of a native colony before it was stopped. Centuries later, Trell awakens again, turning various people into its unwilling thralls and having them corral several children for the purposes of viciously murdering them and empowering itself.

  • Coraline: The Beldam, or the Other Mother, from both the book and movie, is a wicked temptress who lures children into her otherworldly lair with the promise of a better life. The Other Mother spoils them and subtly draws them more and more into the world, eventually convincing them to sew buttons onto their eyes to stay in her realm forever. Once they do, however, she murders them and locks away their souls so as to replenish her energy. She has repeated the process with three children (in the movie, this includes the sister of the owner of the apartment the gateway between worlds is in), and tries to do the same to the titular Coraline. Upon her defiance, the Other Mother kidnaps her parents and forces her into a horrifying game of finding the dead children's eyes. She also casually disfigures her own servants when they resist her, turning the Other Father into an abominated slug. The Other Mother also claims she killed her own mother, as well. Once Coraline wins the eyes, the Other Mother still attempts to catch her, and sends her severed hand into the real world to pursue Coraline once she escapes her clutches. In the film, she also forces the Other Father into attacking his "daughter," and she murders the Other Wybie after he had helped Coraline escape. The Other Mother is one of the most twisted villains in children's literature and stands as a prime example of being careful what you wish for.

  • Darkness Series:
    • Swemmel, the half-mad king of Unkerlant, is probably the single most tyrannical ruler in the story. Seizing power after the Twinkings War, Swemmel's first act as king was to have his twin brother and rival Kyot boiled alive in a cauldron, before launching a massive purge of the nobility. Ruling through fear alone, Swemmel cut a deal with King Mezentio of Algarve to divide Forthweg between them, then invaded neutral Zuwayza while the rest of the continent was distracted by the war against Algarve. When the Algarvians double-crossed Swemmel and invaded Unkerlant, Swemmel sacrificed his own peasants in magical rituals in order to buy time, declaring that so long as he had one subject left at the end of the war and Mezentio had none, he would be the victor. When the war begins to swing in his direction, Swemmel proves himself as bad a winner as he is a loser, enslaving Algarvian prisoners, executing Grelzan prisoners, and boiling "King" Rainero of Grelz the same way he did Kyot. A paranoid megalomaniac, Swemmel finds himself the most powerful man on the continent at the end of the war, and is contemplating starting a new one against his erstwhile allies Lagoas and Kusammo.
    • The unnamed interrogator is a low-level government functionary and professional torturer in Jelgava. Initially an employee of King Donalitu of Jelgava, the interrogator goes over to the Algarvians when they conquer the country, and takes a special interest in would-be loyalist rebel Talsu. Arresting Talsu, the interrogator tries to torture him into giving up names of fellow "traitors", traitors whom he knows do not actually exist. When Talsu refuses, the interrogator instead tortures his wife, until each of them gives up names to save the other.

  • The Dark Sea Annals:
    • Morlan is the Big Bad of the series and the evil brother of King Aravel. He is either directly or indirectly responsible for virtually every evil that takes place in the series. He doesn't seem to start out as this, being the Token Evil Teammate of the Council, but he soon drops right off into this territory. He tricks his brother and his allies into beginning an all-out war with the Gorracks by sending his troops disguised as Gorracks into villages and slaughtering the innocent villagers. He regularly takes part in Black Magic, approves of and assists in Cythraul's ceremonies, and makes a pact with Satan himself. He also killed his father and later his brother.
    • Cythraul, Morlan’s stone-cold, sadistic Torture Technician and right-hand man (or rather, elf), is a cold-blooded killer with absolutely no remorse or mercy in his heart. He is a pure sadist, taking great pleasure in watching others suffer, which mostly takes place in his dreaded Bone Chapel; a temple that is filled with the carefully arranged bones, skulls, and corpses of his victims. He treats his torture of others like an art, knowing every detail in the anatomy of all the races and exploiting them in the most painful way possible. He has no problem with performing his “experiments” on children. He is also a skilled assassin, and tries to kill Abbagael and the baby Telwyn via a poisoned razor on his ring. He even mentally regrets having to kill the baby quickly. This is all just from the first book; he gets even worse in the next.
    • Quevara, the Red Queen, is a viciously seductive, Omnicidal Maniac with a fetish for all things red; namely blood and fire. During her reign, she was The Dreaded, and was infamous for slaughtering her subjects just For the Evulz. This included using them as living torches to light her throne room, (often lighting the children on fire first, and forcing their parents to watch before it was their turn.) and butchering her subjects just to see the streams turn red with their blood. When she was merged with the great dragon Raudrim, she took on part of his savage, greedy nature and became bent on destroying and massacring everything in her path.
  • Daughter of Smoke and Bone: The world of Eretz features this monstrous pair of Seraphim brothers:
    • Emperor Joram leads the Seraphim on genocidal purges of the Chimaera, alongside his younger brother, Jael, enslaving the survivors of their attacks to suffer as their empire grows. Within his empire itself, Joram forces women to become his concubines, mistreating them to the point they have attempted suicide to escape him; he also slaughters his own guards for perceived disrespect. Horrifically raising his own children to become front line soldiers for his armies, Joram shrugs aside their deaths when they are killed for the "glory" of his empire. When he lays siege to the Chimaera capital of Loramendi, Joram sacrifices hundreds of his own troops to weaken the enemy's defenses, then invading the city to massacre the thousands within, both soldier and innocent civilian alike. After winning his bloody conquest, Joram intends to further expand his tyranny, next laying eyes on a peaceful group of seraphim, ever-hungry for more power.
    • The aforementioned Jael leads his brother's elite forces "The Dominion" and is the one who murdered Akiva's mother. His unit feared even among Joram's empire for their brutality, Jael leads them on purges of Chimaera villages, and relishes the chance to murder unarmed women and children personally, as well as torturing prisoners, in one notable case force-feeding the ashes of Ziri's comrades to him. A being of voracious lust, Jael rapes both civilian women and his own female soldiers. Seizing the throne with Joram's death, Jael kills his own nephew and all the guards present for his coup, leaving only his niece, Liraz, alive to become his Sex Slave. Discovering the human Earth, Jael intends to present himself as a messianic figure, then manipulate them into eliminating his enemy races, by manipulating the humans into giving him dangerous weapons to annihilate his enemies. When confronted by Akiva, Jael uses his own men as human shields, caring for nothing but his own selfish conquest.
  • Dead Space: Martyr: In this Tie-In Novel that serves as a prequel to the games, Craig Markoff is a high-ranking military officer who is obsessed with unearthing the Marker. After Michael Altman leaked video footage of two DredgerCorp employees killing themselves, Markoff broke into Altman's house and threatened to kill him if he didn't divulge everything he knew about the Marker. Once Markoff got the answers he wanted, he forced Altman, his girlfriend Ada, and several of Altman's coworkers to work at a floating facility dedicated to retrieving the Marker. Several of Markoff's employees kill themselves or lose their minds due to the Marker's influence on them, but he ignores all the suicides and keeps pressuring them to get the Marker. When Altman escapes the facility and goes public about what Markoff is doing, Markoff confronts Altman again and forces him to return, threatening Ada if he doesn't comply. He punishes Altman by having Krax torture him with knives. When Necromorphs attack the facility, Markoff leaves everyone inside to die while he safely records video footage of how the Necromorphs and the Marker operate. Markoff captures Altman again after he sinks the facility, and he, Krax, and Stevens all gloat how Altman's efforts were futile. He later reveals that Krax murdered Ada, shortly before he and Stevens explain how Altman will become the founder of the Church of Unitology, and that Markoff had Krax killed when he deemed him " expendable". Markoff then has Altman killed by forcing him to fight a Necromorph-enhanced Krax using nothing but a spoon, and continues his research on the Necromorphs and Markers. Even for a series with an already bleak tone, Markoff stands out as a man who wants nothing but power, and considers everyone to be either a weapon to use to his advantage or expendable.

Having abused and abandoned his first creation Deucalion, Frankenstein creates new and improved models that see him as their father and their God, also creating wives for himself only to inevitably grow bored with them or enraged at a minor defect before murdering and replacing them.

  • The Debt To Pleasure, by John Lancaster: Rodney "Tarquin" Winot is the manipulative, smug, and twisted narrator of the novel, using the guise of a "cookbook" to in truth educate the readers on his philosophy in life. Having grown up a rather monstrous child, Tarquin tormented his older brother Bartholomew at every turn, framed one of his nannies for theft leading to her suicide, and directly engineered the deaths of two of his house servants. Once an adult, Tarquin's vile ways only increased, as he murders his parents with an explosion, sends one of his neighbors into the shooting range of some hunters, and poisons his own brother, all while performing needlessly petty acts such as kneeing a child in the face for annoying him. Tarquin ultimately gets away with his crimes by poisoning two journalists investigating him, and gleefully proclaims his ideology that destruction and murder are the "natural beauty" of humankind, singing praises to tyrants and mass murderers for their understanding of "artistic vision".
  • Deepgate Codex: Scar Night brings us Ulcis, the god of chains. After rebelling against his mother, Ayen, and being flung to earth, Ulcis takes up residence in a seemingly bottomless abyss. Using his Herald, Callis, as his representative, Ulcis gathers an army of followers and orders them to construct the city of Deepgate atop of his abyss, promising salvation and a chance at reclaiming Heaven from Ayen to all those who die in his service. This results in the creation of a culture of people who dedicate their lives to waiting to die, creating a high suicide rate, and a total lack of anything approaching an appreciation for life. This is not the bad part. The bad part is that Ulcis is lying. He has no interest in reclaiming Heaven (he'd much rather Take Over the World) and he and his undead horde of angels instead devour the souls sent to him. That's without getting into his treatment of his daughter. Having found an attractive corpse, Ulcis reanimated her, raped her, and then impregnated her, keeping her alive so that he might enjoy her suffering. When his daughter's birth resulted in the woman dying again and being released from her agony Ulcis tried to hang the child from one of the city's foundation chains. When the girl chewed through the rope, Ulcis recaptured her, abused her, and had her gangraped by his undead, gloating that there was no point in taking her soul because by the end, there wasn't one left. When he encounters his daughter again (her having since become an amnesiac Serial Killer), he gloatingly informs her of what happened to her, forces her to recall it, than indicates that all of his soldiers remember her and would love to do it again. "They remember you. My little Rebecca. My little carnival freak."

After being resurrected, he devours hundreds, procured for him by Valeri Rusmanov, to regain his full power. He later kidnaps Blacklight Director Henry Seward and subjects him to brutal torture, including ripping out and eating his left eye in Zero Hour, in which he also kills numerous Operators, including Acting Director Cal Holmwood. He is also responsible for turning thousands of violently unstable inmates into powerful vampires, resulting in numerous deaths across the world.

On a nightly basis, Dante has humans abducted and brought to his personal theater where they are tortured, murdered and eviscerated on stage with their blood drawn for the thirst of the vampires in attendance.

Before escaping, he is in the middle of killing the vampires who are being studied; a young vampire would have been the next victim. He kills the 23 other members of Lazarus with sarin, and was about to kill a teenage member before being shot. We learn that he had done this before, torturing vampires and killing his staff. He is also The Mole for Valeri Rusmanov, and is thus responsible for the kidnapping of Department 19's Director Henry Seward, and the 68 members of Department 19 who are killed—including Kate's boyfriend Shaun Turner—when Valeri leads an attack on Department 19's headquarters. While not having the body count of Dracula or the Rusmanovs, he qualifies as one of the worst humans in the series, despite his seeming-politeness.

  • Discworld is a long-running fantasy series which runs on the Theory of Narrative Causality. Among its villains are these, who put the others to shame:
    • Sourcery: Ipslore the Red is the eighth son of an eighth son and a wizard formerly under the Unseen University, before being thrown out for breaking the rule against marrying or fathering children. Though starting the prologue with the redeeming quality of loving his wife, he is still shown to regard his eighth son Coin, a Sourcerer—a wizard who can use magic without having to learn spells and can allow other wizards to do the same—as merely a tool for revenge and exploits Death by threatening to indirectly kill the boy should Death remove him from Coin's staff. Over the next ten years, Ipslore molds Coin into an obedient killing servant through Electric Torture and by making him dependent on his staff to prolong his revenge, in the process abandoning the love of his wife and losing his sole redeeming trait. In the main story, Ipslore has Coin murder several wizards to bring the Unseen University into line, including a wizard who was kind to the young child, then lets the university loose against the city by turning Lord Vetinari into a lizard—also threatening his pet terrier—and letting the wizards terrorize the helpless population of Ankh-Morpork. Under Ipslore's rule, anyone who attempts to interfere is killed regardless of their inability to stop Coin, a fate that almost befalls Rincewind. Eventually letting his hubris overtake him, Ipslore has Coin freeze the Discworld pantheon, with no care about causing The End of the World as We Know It from the Ice Giants arising or the Things from the Dungeon Dimensions exploiting reality's collapse.
    • Wyrd Sisters: Lady Felmet participated in the overthrow and murder of King Verence I for her husband Leonal to gain the throne for her own benefit and power. Once she inherits her position, she encourages a brutal suppression of peasants and witches alike while using the Fool to spread a propaganda campaign. Revealing herself as a sadist who loves Cold-Blooded Torture, Lady Felmet personally engages in inventive torture with captives.

    • Hogfather: Jonathan Teatime is a sadistic assassin feared even amongst hardened criminals. Implied to have killed his own parents, Teatime has a penchant for excessive slaughter. In one instance, Teatime nailed his target's pet dog to the ceiling for barking too much and killed his servants because he didn't want them to barge in on him. After the Auditors hire Teatime to kill the Hogfather, Teatime abducts a tooth fairy to use her magic to make all the children in Discworld stop believing in the Hogfather in order to kill him, causing a void in Ankh-Morpork's magic that wreaks havoc in the process. Teatime, unlike other members of the Assassins' Guild, shows no regard for the lives of civilians or his own men, in one instance killing a stagecoach driver out of boredom while chatting with him and in another instance having a locksmith working for him dropped down a long spiral staircase to a painful death when he's no longer useful. When Death and Susan foil his assassination attempt, Teatime tails them to the nursery Susan works at in an attempt to kill Death.
    • The Fifth Elephant: Wolfgang Von Uberwald is a sadistic werewolf. Before the book starts, he murders his little sister, Elsa, because she isn't a bimorphic werewolf and, as such, is "impure". He takes the werewolf tradition of hunting humans through a forest, and adds the cruel twist of giving them the illusion that they've escaped before ripping them to shreds. He doesn't care about all the political power he and his family can gain through the civil unrest; he just likes being sadistic.
    • Night Watch: Captain Findthee Swing, the leader of the Unmentionables, is the reason his time period is so corrupt.

When Vimes enters Swing's base, Vimes sees people who have been physically and mentally tortured, one of them is so broken that he does not resist when Vimes kills him without hesitation. Vimes finds Swing about to torture a man tied to a chair, before he comes in to fight Swing to the death.
  • The Divine Comedy: Dis/Satan was once "the highest of all creatures", above every angel and man gifted by the Highest Joy with immortality, invincibility, super intelligence, and perfect happiness. However, Dis came to love his superiority to the lower angels and only that superiority, making the supremacy of his Father unbearable. In acting on this pride, he convinced his fellow angels and the first humans to rebel against the Love known as God. With his rebellion, the Devil introduced all the evil, suffering, and death that would ever be into the world while condemning any who followed him to Inferno, a realm where beings built for eternal Paradise have been corrupted into murderers drowning in the fiery blood of their victims and cannibals biting into the corpses of their children. With his angelic intelligence, Dis knew all of this would happen if he carried out his "arrogant rape", yet brought all of the tortures and crimes described in Inferno into existence without any remorse.
  • Don't Be a Hero, by Chris Strange: Doll Face is a horrifying and childish psychopath with a desire only to hurt others. Having grown up bullied, Doll Face first used his terrible powers to seek vengeance on his tormentors; however, he quickly grew a taste for blood and power, and began using his powers on innocents worldwide. Be it forcing children to eat their own faces or turning others into his personal killing machines, Doll Face racks up a body count in the hundreds, and though seemingly killed after turning a school into a slaughterhouse where children cannibalized and murdered each other, Doll Face in truth was locked away by the government. Freed from his confinement by Quantra, Doll Face gleefully assists his new boss in brutally torturing and mentally destroying the young superpowered teen Sam, hoping to turn the boy into a walking weapon who will kill countless people. After Quantra is beaten, Doll Face takes matters into his own hands, skinning dozens of his own men alive then using them as meat puppets to hold back any heroes while he himself finishes driving Sam insane. Taking an unholy glee in his actions that disgust even Quantra himself, Doll Face was a truly repulsive monster who got his kicks from hurting defenseless people.
  • Dracula: Count Dracula himself is the Trope Codifier for the modern vampire. A hideous, blood-sucking monster, Dracula commits a number of crimes over the course of the novel, including keeping Jonathan Harker prisoner and trying to drive him insane; kidnapping a baby to feed to his fellow vampires, before sending wolves to kill the mother when she demands her baby back; driving his own servant, Renfield, to madness; sending a wolf after Lucy Westenra and her mother to gain entry to her house before draining her blood and turning her into a vampire (killing Lucy's mother through sheer fear at the wolf's appearance in the process); and turning Wilhelmina "Mina" Harker into a vampire to uncover his enemies' plans against him. Dracula ultimately plans to move to England so that he can feast on the people of London to his heart's content. Overall, the vampire Count is an undead abomination devoid of humanity and worthy of no sympathy.
  • Dragon Age: The Stolen Throne: King Meghren is the tyrannical cousin (and rumored incestuous lover) of the Orlesian Emperor, exiled for offending said cousin to rule Ferelden in his stead. Despising Ferelden and its people, viewing them as "uncultured dogs", Meghren vents his hatred out by tormenting his people, mostly through torture parties or mass executions and vehemently refusing to make any sort of appeal to them. Notable examples include intimidating a young noble over a birthday present just to get a kick out of his fear, and at another point beating a servant boy to an inch of his life. Despite all this, he expects the people of Ferelden to cater to him and is offended when they ask anything of him, or rebel against him. When a rebellion by Queen Moria rises against him, Meghren has her decapitated with her head impaled on a spike—a frequent punishment of his—and resolves to hunt down and eventually kill her son Maric. This war results in high casualties on both sides, with Meghren frequently asking for Orlesian support, only to carelessly send his men to their deaths. When he believes Maric has been killed, only to learn of his survival, as the majority of Ferelden rise or turn against him, he flies into a rage, ordering the mass execution of anyone and everyone who sympathizes with the rebels.
  • The DragonCrown War Cycle, by Michael A. Stackpole: Chytrine, Empress of the arctic realm of Aurolan, has a heart as cold as the tundra over which she rules. She mercilessly drives her subjects to war with blatantly false propaganda, uncaring if they die so long as they advance her goals in doing so, and the conquered territories her forces occupy are treated so brutally that their populations can be reduced to a tenth of what they were in a matter of years; a century of her rule can turn a once-prosperous nation into a wasteland. Chytrine is utterly without empathy or loyalty; when her adopted daughter Isaura turns against her, she coldly declares that she has no daughter and attempts to kill her, and though she gets a good portion of her power through her worship of the Oromise, she secretly fantasizes about overthrowing and enslaving them as well. Though she herself is half-dragon and is allied with several full-blooded dragons, she plans to betray her kin by re-forging the titular Dragon Crown, giving her the power to dominate most of their race. Her vilest deed may be how she gets her Quirky Miniboss Squad; Chytrine has a fondness for using Fallen Heroes as her lieutenants, tricking them into swearing allegiance to her in moments of weakness and then forcibly remaking them into undead warriors in a process that is supposed to be unspeakably agonizing and twists their personalities to be more in line with her desires, leaving just enough of their original selves to be horrified by what's been done to them. The nations of the south lived in fear of Chytrine for generations, for very good reason.
  • Dragon Prince:
    • High Prince Rolestra is a petty, cruel Evil Prince with a very high level of depravity. After murdering his father at the tender age of eight, he ascends to Princemarch's throne and used his position to play other princes against each other for his own amusement, nearly causing several wars. When his request for a Sunrunner was refused he trapped and addicted one to drugs, then slowly cut off the Sunrunner's supply of drugs when he ceased to be useful. He then attempted to use these drugs to enslave and rape another Sunrunner, Sioned, and when he fails burns his mistress Palila alive and banishes two of his children, one being a newborn. When we next hear about him he has cornered the market on the only medicine to a plague and only supplies it when enough of his rivals have died of it. When he enters a war with his greatest rival left alive, Rohan, he salts a battlefield after losing a battle out of spite.
    • Princess Ianthe, Rolestra's daughter, is a cruel and heartless woman, and just as vile as her father. She causes several of the events that lead to Palila being burned alive and her sisters being exiled simply because she didn't like them. She then concocts a plan with her father to kidnap, drug, and rape Rohan to make her son heir to the Desert. When his wife, Sioned, comes to rescue him she locks her in a lightless room and has her guards rape her for a month straight. When she finally lets them go, she releases them into the desert with only a little water and no food.
    • Mireva, a sorceress from the mountains, is a bitter and power-hungry woman. Prior to the events of the story, she introduced drugs to Palila that kickstarted several of Rolestra's villainous acts. She helps Ianthe's sons escape the fire she dies in and trains them into her tools to try to conquer the world with. While orchestrating these plots, she enslaves a princess with a mirror, forcing her to raise an army to try to invade Princemarch, which would cause the death of hundreds of people, if not more. She kidnaps a princess named Ruala with latent sorcerer powers to use as a power source and tries to blackmail another prince to do the same to him. As part of this plot she also impersonates a princess and rapes Rohan's son Pol, then has one of Ianthe's sons nearly rape the princess disguised as Pol. She also threatened to murder two children due to wanting revenge on a Sunrunner.
  • Dragonriders of Pern:
    • Lord Holder Fax managed to gain control of seven Holds through various means, mostly conquest. One Hold, however, he "won" by marrying into the leadership...and then doing his level best to kill his Lady wife via childbirth. He also had zero problems with killing every man, woman, and child even suspected of having Ruathan blood in his bid to gain supremacy over that Hold. It's also heavily implied that he if not outright raped, then stole and coerced every half-pretty female in his jurisdiction that he could get his hands on.
    • Lord Holder Chalkin had a jail area that was more or less like a freezer, with small "cells" cut into rock, all of them cold and damp, into which he threw anyone that pissed him off in the slightest. A servant spilled a container of sugar and got two weeks in one of these cramped, cold cells. People were frequently kept in the cells until they died of the cold and damp, and their bodies were thrown into a lime pit, rather than given whatever passed for a normal burial. He was also heavily "tithing" his peoples' produce, whether it was food or textiles or what have you, to the point of forcing his people to starve and work themselves to death in an effort to please him while he wallowed in an excess of supplies of all kinds.
  • Dragons of Requiem series:
    • Dawn of Dragons trilogy:
      • King Raem Seran sees all Vir Requis as diseased creatures who must be purged from the world by any means necessary. Ashamed of being a Vir Requis himself, Raem has multiple Vir Requis executed in public. After discovering his son, Sena, is a Vir Requis too, he immediately tries to kill him, only stopping because Issari, his daughter, begs him not to. Fed up with the sheer amount of Vir Requis in his kingdom, Raem summons a demon named Angel and has her army seek out and slaughter any Vir Requis they find as they rape many of the women in Eteer. He also allows a witch to extract blood from Issari in exchange for information regarding his exiled daughter, Laira; Raem later hires Zerra Blacksmith to kill Laira and the remaining Vir Requis in the north. Once his initial plans fail, and Raem discovers that Issari is a Vir Requis after she tries to kill him, Raem allows Angel and her demons to feast upon the innocents in Eteer so they'll grow stronger and will assist him in hunting Issari and the other Vir Requis. As they hunt, Raem lets his demons feast upon any villagers they find before confronting the Vir Requis army and killing dozens in the ensuing battle. Raem later contacts the Widejaw tribe and turns them all into sphinxes before ordering them to destroy Requiem and kill any Vir Requis they find. Frustrated over his own "disease," Raem spends his free time executing many innocents in the Abyss, before ordering Angel's demon army to eradicate all life on earth.
      • The aforementioned, ironically-named Angel is Queen of the Abyss, and a fallen deity. Upon being summoned by Raem, she immediately tries to drag him to the Abyss so she can torture him, only stopping because Raem holds all control over what she does. While Raem only wants Angel to kill all the Vir Requis in Eteer, she begs him to allow her and her demons to rape hundreds of women in the city too, which Raem agrees to. Angel and her demon army Rape, Pillage, and Burn as they please while Angel keeps begging Raem to let her army feed on human flesh as well—an offer Raem later agrees to in order to strengthen her army. As Angel's demons continue to wreak havoc upon the neighboring communities, Angel stays in Eteer to ensure her demons keep raping and impregnating as many women as possible. When Issari and many other Eteerian soldiers capture her, Issari tries to take control over Angel, only for her and the hundreds of pregnant women to give birth to half-demons who proceed to slaughter even more innocents. Angel continues to rape and kill indiscriminately while her army massacres villages and cities around the country. During the final confrontation between Angel and the Vir Requis, she starts mind raping some of the characters by making them believe that their fallen loved ones are being tortured in the Abyss. While Raem was driven out of shame and the need to purge the world of Vir Requis, Angel only cares about causing as much death and destruction as possible to satisfy her lust and hunger.
    • Song of Dragons trilogy: Dies Irae is responsible for nearly driving the Vir Requis into extinction. Shunned by his father for the inability to shift into a dragon, unlike his brother Benedictus, Irae takes out his frustration by raping and possibly impregnating his brother's fiancée, Lacrimosa. Upon finding out that Benedictus will take the throne, he kills his father and declares war on the Vir Requis. As he hunts them, he kidnaps Lacrimosa and Benedictus' daughter, Gloriae, and trains her to hate and kill the Vir Requis as well. When Irae discovers that there are still four Vir Requis left in the world, he sends his armies to hunt them all down, not caring how many innocents are caught in the crossfire. After he's defeated by Benedictus, and Gloriae releases the nightshades, Irae banishes Gloriae from his kingdom. While mad that the nightshades harmed his kingdom, he later takes control of them, allowing them to terrorize the world and suck the souls out of thousands of people. Irae also takes his frustrations out on his own soldiers, going as far as having 300 of his men beheaded because they failed to kill any Vir Requis. Irae faces Benedictus and Lacrimosa a second time, and he succeeds in killing his brother before escaping and creating an army of mimics. Not content with using dead body parts, Irae builds a camp where he kidnaps thousands of individuals and harvests their body parts while they're still alive, and even hacks off Agnus Dei's hand. Irae sends his army to finish off the remaining Vir Requis once and for all, and during the battle, he kills Lacrimosa even after she confesses that she's pregnant. A racist Evil Overlord driven by his hatred of the Vir Requis, Dies Irae stands out as being one of the worst villains in the franchise.
    • The Dragon War trilogy: Emperor Frey Cadigus is the vicious, tyrannical ruler of Requiem. Viewing the Vir Requis as weak, Frey staged a coup where he murdered everyone in the Aeternum family and overtook the throne. Afterwards, he spent several years recruiting thousands for his army; after they're put through Training from Hell, he sent his forces out to exterminate all the surrounding nations, leading to the deaths of millions. When the Resistance is formed, Frey has all his soldiers hunt down and destroy the organization, going as far as imprisoning or publicly executing anyone allied with them and opposing his empire. Once Frey discovers that Rune Brewer, the sole survivor of the Aeternum family, is still alive, he sends his troops out to hunt him down. When the Resistance retakes Lynport, Frey and his troops fly down to the city and destroy it, killing anyone in their path. Frey also lures Rune out of hiding by killing several hostages, two at a time. Frey keeps Rune alive, but only so he can torture him and convert him to his empire. During the final battle between the Resistance and Frey's troops, Frey subdues his own daughter, Kaelyn, and ties her and Rune to a chair. He then points a gun at both of them and tries to make Valien choose which person he should kill. Although Frey claims that he cares about Requiem, he uses his power to imprison, torture, and kill anyone in his way, even those who pose no threat to him.
    • Requiem for Dragons trilogy: High Priestess Beatrix Deus is the new Requiem ruler and the leader of the Cured Temple. As ruler, Beatrix routinely sought out any Vir Requis who could shift into dragons and exposed them to tillvine in hopes of ridding the Vir Requis race of their transforming power. Anyone who refused to be "cleansed" with the tillvine was either murdered or imprisoned and tortured, resulting in thousands of casualties. After Beatrix hears that Eliana, the stepsister of Cade Baker, has the power to turn into a dragon, she sends her daughter Mercy to expose her to tillvine, only to discover that Cade is a Vir Requis too. When Mercy fails to find Cade, she burns down his village and murders his stepparents. Once Beatrix realizes that there are other Vir Requis who oppose her rule, she tells Mercy to hunt them down by any means necessary, and later imprisons her own son Gemini to be tortured to death after he inadvertently allows two Vir Requis to escape. She later orders Mercy to murder thousands of infants when her supply of tillvine runs low and declares war on the Horde, resulting in the deaths of hundreds of thousands. Due to Mercy's repeated failures, Beatrix summons an army of bonedrakes to sniff out the Vir Requis and finish them off. In the final battle, when she's confronted by her former lover, Korvin, who tries to persuade her to surrender peacefully; Beatrix responds by subduing Korvin and orders her guards to hang him from her Temple's balcony. While Beatrix acts like she cares about the Vir Requis, she's really a hypocritical, abusive mother obsessed with "curing" the Vir Requis of their "disease," even if it means taking innocent lives.

A former slaveholder himself, Snyder exploits cheap labor from the colored populace of Summerland with any infractions he can think of ruthlessly punished by his son, the town's sheriff, with torture and abuse wide under his rule. Beyond this, Snyder throws away the lives of countless of Summerland's colored populace by forcing them to patrol the walls fending off encroaching shambles, utterly uncaring about the massive death tolls and always justifying himself and his cruel rule by claiming to only serve God's chosen order. Lecherous, sexist, racist, and a proud hypocrite above all else, Snyder ignores that his sanctimony will eventually doom the entire town and everyone in it to the hordes outside.

    • Blood Rites: Lord Raith, aka the White King, is one of the cruelest White Court vampires, as well as one of Harry's most personal enemies. A brutal authoritarian, Raith murders his sons to avoid them becoming a threat to his power, and rapes and feeds off his daughters, reducing them to sex slaves. Feeding off of the feeling of lust from his victims to sustain his power, Raith only stops this when he kills Margret Le Fey Dresden—Harry's mother—and she uses her death curse to prevent him from continuing. When Raith's servant Arturo begins operating independently of Raith's porn monopoly, Raith furiously responds by slaughtering Arturo's innocent employees, only stopping to hunt Harry to lift Margert's death curse.

Capturing Thomas, he has him tortured by having him hung up and than ripping strips of skin off him, piece by piece.

The Red King presides over a court that enslaves mortals as Cannon Fodder, slaves and food, with a special emphasis placed on feeding upon children, as well as Human Sacrifice to his own glory. When war begins between the wizard White Council and the Red Court, the Red King shows that he had already been prepared for a protracted and brutal war by launching violent attacks, including poison gas, with civilians being collateral damage at best, and food for his soldiers at worst. Playing the part of a blood-addicted junkie, the Red King manipulates his courtiers, pitting them against his enemies and one another, and shows no compunction in sending his own daughter to her death when she opposes him. The misery of the Red King's actions makes South America into a living hell for civilians and those who dare to oppose the vampires, and is so horrible a formerly loyal servant is driven to Knight Templar levels to destroy the Red Court at any cost. One of the most ancient, powerful and evil vampires in existence, the Red King is finally brought down by a sacrificial spell he intended for Harry Dresden's entire family line—one he was going to initiate by sacrificing Harry's 8-year-old daughter personally on the altar.
  • The Drowned Cities: Lieutenant Sayle is Colonel Glenn Stern's right-hand man, and acts as The Heavy for most of the book. The oldest soldier in Stern's service, Sayle acts as a recruiter, press-ganging children into becoming soldier boys for the United Patriotic Front, burning their rank into their faces with acid, and convincing them that the outside world has nothing to offer them. A particularly cold-blooded sadist, Sayle started the UPF's practice of mutilating prisoners by cutting off their hands and feet and leaving them for their comrades to find, and put out of their misery. The practice eventually spread to other child armies, like Taylor's Wolves and the Army of God—which Sayle intended because it means that his own boys will be less likely to surrender. Sayle treats civilians with an even more deliberate brutality, endorsing, encouraging, and participating in his boys' practice of Rape, Pillage, and Burn; he's particularly vicious towards women, informing the heroine, Mahlia, (while neck lifting her) that "maybe I'll just stand here and watch you kick. I like it when a pretty girl kicks." During the climax, Sayle even manages to violate the soldier boys' tenuous moral code, when he has one of his own boys (Mahlia's former friend Mouse) mutilated in order to try and break Mahlia, a fact that shocks and disgusts his Number Two, Sergeant Ocho. What makes Sayle especially bad is that he doesn't buy into Colonel Stern's Well-Intentioned Extremist rhetoric, nor is he a drugged-up PTSDing child, like most of his boys. Ocho notes that Sayle is Straight Edge Evil because "what got him high wasn't any booze or drug or girl. It was the hurting. Sayle liked people hurt."

When Feyd tries to assassinate Harkonnen, Harkonnen, in amusement, forces him to kill every woman in the pleasure quarter, chiding him "there will always be more women, Feyd." At one point, a character comments Feyd might have become a great hero, if only someone who wasn’t such a monster had raised him.

Using a cold-blooded exterior to mask her raging insanity, the Commandant delights in committing torture and murder for the flimsiest of reasons. Introduced as she is whipping a boy to death for deserting, a not-uncommon situation, she keeps a wall of her office completely covered with dozens of wanted posters from those she's captured and had killed, a grim "paper cemetery" that serves as a trophies of the lives she's taken. The Commandant treats her slaves horribly, disfiguring them within the first few weeks of service, torturing them or their loved ones for the slightest mistakes, and has a track record of driving them to suicide with her abuse. After the Commandant caught one member of the resistance, she killed everyone the woman loved, savaged her face, forced her to swallow hot coals, then enslaved her as her cook. When Cook tried to assassinate her with poisoned food, the Commandant responded by driving a hot poker through the eye of a five-year-old slave that Cook saw as a surrogate daughter. Conspiring with the Nightbringer, the Commandant places a psychopathic rapist on the throne as her puppet, whom she plans on killing and usurping, manipulates the local Scholar resistance into killing the old emperor, then uses their rebellion as an excuse to commit genocide on the Scholars. The only moment of compassion she's ever admitted to was when Elias was born, and a fleeting moment of maternal instinct caused her to abandon him with a tribal woman instead of killing him as she planned. She almost immediately regretted this and turned around to murder him, only to find the tribe was already gone. She's regretted that single moment of compassion ever since, and has worked to undo her mistake by repeatedly trying to kill her son in the present day. The Commandant is defined as someone who's forged herself into a monster by tirelessly working to weed out any goodness within her in pursuit of absolute power.

His hatred of women beginning when his mother spent too much time dating men who could provide for them, the Killer grew to view her as nothing but a filthy whore, a mindset he then attributed to all women. Once losing his job, he begins killing women to make himself feel powerful simply because he's too lazy to find another job, meaning his wife Alison is the provider for his family, which makes him feel weak.

In the end, he flies into a rage when he discovers Ruby is not his biological daughter, and attempts to torture and kill her in front of Alison, murder Alison herself, then move on to her parents and continue his spree, with him practicing for Ruby's death by attempting to kill an infant in front of its mother.

  • False Memory: Dr. Mark Ahriman uses his status as a psychiatrist to mind rape his patients and use them however he sees fit. Some he sends to commit homicide and/or settle his personal vendettas, some he drives to creative suicide for his own entertainment and some he uses for other things.

If the patient is a pretty woman, she's probably screwed, in many ways. He gets away with it for twenty years before anyone properly catches him.
  • Fantômas: Fantômas, the Villain Protagonist, is a terrifying sociopath and Master of Disguise who holds all of Paris in terror as he could be anyone in the city and you'd never know it before he slit your throat. Through the first novel, his activities are so extensive it is unclear if "Fantômas" refers to a criminal network acting together, but by the end of the third, novel it is clear there is only one Fantômas. Known as the "Man of a Thousand Faces" and the "Lord of Terror," Fantômas commits murder after murder, for personal power, wealth or simply his own amusement. Not even his own children are safe as Fantômas uses his son and daughter as pawns in his schemes and kills his own son's girlfriend to twist him to Fantômas's purpose. Fantômas routinely frames the innocent to face the guillotine for his crimes, and puts special emphasis in mentally tormenting the Hero Antagonist Inspector Juve. Fantômas also loves committing murder in elaborate ways: from strangling, stabbing and poisoning to more elaborate death traps such as chambers filling with sand, or even unleashing plague-infested rats on an ocean liner. Alan Moore once summed up Fantômas well in The League of Extraordinary Gentlemen: "The Count had once been human. Fantômas was a thing. He had always been a thing."

While working as a security guard at a mall, he notices an android based off Henry's daughter Charlotte along with her six friends, and decides to try and kill them For the Evulz. He kidnaps Charlotte's friend Carlton and places him in a springlock suit, gleefully telling him that if he makes one wrong move, the suit will slowly crush him to death and his spirit will be unable to pass on. He later kills an officer and takes Charlotte hostage when the group tries to escape. Returning as Springtrap, Afton sends out animatronics to kill Charlotte and her friends out of revenge for causing his death. It's also revealed that he reduced the animatronics to their endoskeletons and mashed them together, keeping all of the souls in excruciating agony.
  • Flickers, by Arthur Slade: Absalom Cecil is a mysterious, wealthy film producer in the Silent Age of Hollywood seeking to make the world's first sound film for his own nefarious purposes. Responsible for sacrificing a part of himself to bring the hornet-like zebûbs into the world, Cecil uses them to murder an upstart farmer after initial attempts to retrieve his two infant children Isabelle and Beatrice fail, fully intending on murdering the latter in the process and only sparing her to use as a tool once she inadvertently survives. Raising the children under subtle emotional abuse and torturing them when they get out of line, Cecil sets up an orphanage for the pure purpose of picking children to feed himself—even comparing it to a slaughterhouse—and only relents when he's found out, murdering the orphan who gets too much detail and massacring all of the orphans himself before using his servants as an alternative food source. Callously murdering any other threats to his plot, be it with his own hands or through the zebûbs, Cecil ultimately reveals he's a Humanoid Abomination from outside reality who seeks to let the rest of his kind into the world with the implied intention of devouring all humanity, attempting to force Beatrice to watch as Isabelle is devoured before her eyes by his eldritch "twin." Unflinchingly ruthless in pursuing his goal and willing to raise two children for years at a time purely to use them as tools, Cecil is an unfeeling monster barely able to pass as a human being.

  • Fragment: The evil scientist Thatcher Redmond originally comes across as just a Smug Snake with a nihilistic worldview, but only pages after we meet him, we find out that he killed his love child to avoid paying child support. He drips with contempt for humanity, and when faced with the incredibly deadly Henders life forms, he sees the opportunity to advance his plans. He leaves his fellow scientists to die on Henders' Island, does everything he can to eliminate the intelligent and gentle Hendropods, and indisputably crosses the Moral Event Horizon when he releases five Henders Rats onto the ship with the intention of unleashing them on an unprepared humanity. The guy's as close to an Omnicidal Maniac as a normal human villain can get.
  • Frankenstein: The Shadow of Frankenstein: This tie-in novel to the Universal "Frankenstein" films features Jack the Ripper. During his original killing spree, he used his victims' wombs in a potion to grant him immortality. Initially he felt remorse over his first murder, but he immediately embraced his enjoyment of killing (as otherwise the spell wouldn’t work). About half a century later, the effects of the potion are wearing off, so Jack continues killing and mutilating several prostitutes. Jack meets the Monster, who had befriended some of the women. As the Monster desperately tries to save Jack's dying victim, Jack taunts him. Discovering the Monster's near-indestructible body, he kidnaps Dr. Frankenstein's wife Elizabeth and holds her hostage to force Frankenstein to create him a new body like that, so he can live forever. He also stabs a man who tries to expose him, cuts off the foot of Frankenstein's best friend and leaves it as a "souvenir" to give Frankenstein a ransom note written in blood. Out of any character in the Frankenstein series, Jack the Ripper truly is a monster.

  • Friday the 13th: The Jason Strain, by Christa Faust: Caleb Carson is a Corrupt Corporate Executive whose pride and joy is Xtreme Elimination 2, a reality show in which Condemned Contestants are pitted against each other and "special guest" Jason Voorhees in the jungles of South America. After Jason is kidnapped from the "set" and unintentionally given the ability to spread a zombie plague by a group of scientists, Carson becomes psychotically obsessed with salvaging his series, going as far as having his mercenaries massacre the facility that had developed a cure for the virus so that he can abduct Jason and the other remaining competitors from it and start over in America, not caring that Jason was still highly contagious and could potentially end all life on the planet if not given the vaccine. Carson afterward reveals that he had framed "star contestant" Butch Malone for the double homicide that landed him on death row, knowing that the only way he could get Malone to agree to compete on Xtreme Elimination 2 was by ruining his life and leaving him with no other option, with the worst part being that Butch never had a chance of winning anyway and was set up from the start to die a "dramatic" death in the final round of the game.
  • Fusion Fire: Dru Polar is one of the top-level leaders of the Shuhr. Polar is in charge of training up the teenage "potential adults", and all of them live in terror of him and his mercurial moods, as upsetting him—no matter how trivial the reason—will lead to their death, most likely as an involuntary test subject. He is also determined to increase his already off-the-charts Psychic Powers. In trying to reach this goal, he experiments on live people, subjecting them to a painful process without anesthetic or sedatives, a process that has killed every subject he's tried it on before he could actually test his theory. The Shuhr culture is ruthless, cutthroat, and revels in the pain of others, but even the other high-ranked Shuhr, ostensibly his peers, regard him as cruelty-obsessed and tread cautiously around him in order to avoid attracting his ire.
