Learning of Helena and Sarah's connection and of Sarah's daughter Kira, Tomas orders Helena to kill Sarah and abduct Kira, locking her in a small cage when she refuses. During a later confrontation, it's made clear that Tomas intends to put Kira through the same treatment as he did Helena, which ultimately turns Helena against him. When later rescued by the Johanssen branch, Tomas makes it clear that he sees Helena as another abomination, and his only objection to the idea of Helena having children is his belief that those children will be monsters as well.
    • Season 2: Henrik "Hank" Johanssen is the leader of a branch of the Prolethean cult, operating on a ranching community. Separating from the Prolethans' more traditional views in favor of scientific curiosity, Johanssen operates his branch, and seemingly peaceful community, as a Breeding Cult, where women are artificially inseminated and children are regularly abused. When Henrik gets his hands on Helena, discovering she's a rare fertile clone, Hank has her handler Tomas killed so he can keep her. He proceeds to drug and forcibly marry Helena before taking her ovaries and fertilizing them with his sperm, planning to implant those embryos in multiple women. When Helena escapes with the help of Hank's teenage daughter Gracie, Henrik has Gracie locked in a cage and her mouth sewn shut as punishment; it's implied this is a usual punishment for her. When Helena returns, Henrik has her inseminated with their embryos before proceeding to do the same with Gracie. He keeps them locked in a nursery, holding them at gunpoint and sends his wife to find more women for him to impregnate. Henrik's motivations are that since a fertile clone is a scientific impossibility, he's the only one worthy of fathering children with them and spreading his genes in "miracle babies."
    • Season 4's Big Bad, Evie Cho, is the ambitious, high-ranking, Neolutionist CEO of BrightBorn. A survivor of a birth defect, Cho developed a perfectionist view, which inspired her goal to control the future of human evolution. Cho developed mechanical, worm-like devices to alter people's DNA and can quickly but painfully kill it's host if ruptured. When Beth Childs was investigating the Neolutionists, Cho tried to get her to kill Susan Ducan, so she can usurp Duncan as leader of Neolution. Failing that, Cho blackmails her into killing herself by threatening the other clones. It's also revealed that she had Delphine Cormier shot at the end of season 3. When Cosmia explores BrightBorn facilities, she discovers Cho is keeping pregnant women in maternity labs for illegal human experiments. When these experiments result in the babies being born deformed, or any other imperfection such as blindness, Cho would have the babies euthanized to cover it up. Cho has Cosmia's research to help cure the clones diseases destroyed, and has Kendall killed and incinerated in front of Cosmia, making it impossible for the clones to find cures. To further wound her, Cho tells Cosmia that Delphine is dead. She plans to put her devices into millions of people and alter their DNA without their consent. She has Donnie arrested with threats of having him killed in jail to blackmail Allison. When two women escape her maternity lab with evidence that could expose her, she sends assassins after them. When exposed and given the option to resign and absolve BrightBorn of any wrongdoings, she refuses, her Villainous Breakdown when the project might move forward without her showing she doesn't so much care about controlling human evolution, as much as she cares that she's the one doing it.
    • Percival T. "P.T." Westmoreland, actually John Mathieson, the Big Bad of the 5th and final season, is the ultimate villain of the series, posing as the founder of Neolution and has been behind all its atrocities. Stealing the real Westmoreland's identity, he goes on to create a cult to his name on an isolated island while he runs Neolution behind the scenes. Seeking immortality, he sustains himself by taking the blood of the children of his cult, resulting in some of them dying, and even experiments and tortures a boy named Yanis, driving him feral before eventually killing him in front of Cosima. His next plans is to find, harvest and fertilize eight year old Kira's eggs, to spread and study the "Fountain of Youth" gene in her offspring, something he is steadfast in, even when his true identity as Mathieson is exposed. Viewing the project LEDA clones as little more than experiments, he feigns a fatherly affection to Rachel, while secretly spying on her every action through her prosthetic eye. When the truth of Neolution is exposed, he becomes more unhinged; has Helena abducted to force her to give birth to her twins for further experiments; kills his backers to cover his tracks as much as possible; and has Dr. Virginia Coady kill Mark now that the project CASTOR clones served their purpose. It's revealed his end goal is to create a serum that would permanently reverse cell damage for the upper class—mainly himself—and have the rest sterilized by the CASTOR pathogen. Ultimately, John Mathieson is little more than a selfish madman that manipulates an ideology and orchestrated atrocities for little more than his personal power, and the expansion of his own life.
  • The Orville: Kaylon Primary is the leader of the robotic Kaylon race ever since he and his brethren rebelled against their once-cruel masters and wiped them out completely. Primary posts the Kaylon emissary Isaac on the Orville to gather intelligence on other biologicals, having concluded that the Kaylon have exhausted their planet's resources and must create an interplanetary empire and exterminate all biological lifeforms to thrive. Primary has the Orville boarded and commandeered after killing all its security personnel, intending to use the Orville to ensure that Earth will lower its defenses for the Kaylon fleet. Primary forces the bridge crew to play along under threat of killing the rest of their crew one by one, then destroying another Union ship after Captain Mercer tries to warn them and forcing him to watch a helpless ensign being ejected into space. Worried that Isaac might have become too sympathetic to organic beings, Primary orders him to desist before trying to force him to kill Ty Finn or be destroyed himself. When Isaac turns on the Kaylons and kills Primary, the Primary's last words are to spitefully curse Isaac that he will always be alone.
  • Out of the Ashes (2003 Showtime film): Dr. Josef Mengele is one of the leading Nazi commanders of Auschwitz concentration camp, whose polite demeanor belies his sadistic nature. In charge of determining which women are to be gassed and cremated, he also leads torturous medical experiments on the prisoners without anesthesia, euthanizing the subject once the test is done. Paranoid of disease within the camp, Mengele massacres entire barracks if a person is found to be sick. Upon first meeting Gisella Perl, he deceives her into sending several pregnant women to the gas chambers, solely to spite her for asking to be reunited with her family. After Auschwitz opens its first infirmary, Mengele conscripts any doctors among his prisoners, killing several when Gisella initially refuses to join him. Fascinated with reproducing pure Aryans, he orders the delivery of twins from a gypsy woman to study them and, when the woman puts up a struggle against euthanization, Mengele viciously shoots her. Even years after Auschwitz was liberated, Mengele's crimes continue to haunt Gisella and her fellow prisoners.
  • The Outer Limits (1995):
    • "Living Hell": Wayne Haas is a vicious murderer who targets women. Several years before, he had a neural transmitter installed in his brain which inadvertently allows Haas to share his thoughts with any person who possesses the same implant, although Haas is mistakenly believed to have since died. He's first shown chasing a woman through the woods and killing her, before deciding to play around with the corpse when he notices his "audience," the episode's protagonist Ben Kohler. He later hires a prostitute, and, for fun, forces Ben to witness how he gruesomely stabs her to death in his bathtub. When Ben investigates Haas's apartment with the doctor responsible for the implant, Haas kidnaps her to cut out her brain and leaves Ben behind to take the blame for the other women the police claim he murdered over the previous months.
    • "Tribunal": Karl Rademacher, during The Holocaust, was the SS commandant of an Auschwitz subcamp made up to look like a "model" camp for inspections by the Red Cross. When they leave, he usually has the prisoners gassed by the hundreds. The episode opens in 1944 as Rademacher makes his daily rounds to select a prisoner to execute in front of the rest, which he considers "the only joy I get from this miserable job". When he selects a random man, the wife begs him not to, so he selects her instead and shoots her in front of her husband and daughter, later having the child gassed to death. He gives instructions to the prisoners to write letters to their relatives to tell them how wonderful they have it there. When one man objects, Rademacher orders him sent outside and shot, before amending the order so he can personally shoot the prisoner. After the war this unrepentant war criminal lives incognito for many decades in the United States. Rademacher's cruelty and brutality ultimately becomes his own doom when, thanks to a Time Travel device, he is sent back to his own camp dressed up as an inmate. When his younger version runs into him, he demands that the rowdy old man beg for his life before he kills his older self for being Jewish.
    • "Better Luck Next Time": Two Energy Beings have been living on Earth for centuries, stealing host bodies and using them to commit murder after murder for amusement and to alleviate boredom; Ripper one of said energy beings was Jack the Ripper himself. Detectives Terri and Girard end up each working with an alien, both claiming they are officers sent to hunt down the killer. At the end, the truth is revealed: the two are partners in crime and have been playing the officers for fun with the only excuse being how bored they are as immortals. The two have been spending centuries playing their games and corrupting good people into killing their friends and partners out of paranoia; they plan to hijack Terri's body after she mortally wounds Girard and use her police connections to have even more fun. When Terri and her dying partner mortally wound both killers' host bodies, Terri opts to kill herself to prevent them from stealing her body, knowing they can't survive long without hosts and unwilling to allow them to continue their rampage.
  • The Outsider: The Outsider itself, "El Cuco", is a sinister monster who preys on suffering. With children as its preferred food source, El Cuco attacks them in the guise of a beloved community figure, rapes and devours them for its own sick pleasure, then frames the one whose form it takes before lingering to enjoy the pain of the community. Infecting proxies to do its bidding and torturing them into compliance, the Outsider attempts to deflect attention by having any cops after it killed, plotting to continue its horrific actions to feed on and enjoy the pain of its victims.
  • Oz: Even in this Crapsack World inside a Hellhole Prison, a few characters stand out:
    • Timmy Kirk is a sociopathic murderer who gets by in Oz despite his mediocre intellect and physical strength, due to his sheer ruthlessness and treachery. A flashback shows that he was incarcerated for homicide after putting a baby, implied to be his own, in a rat-infested dumpster, over the desperate protests of its mother. Initially a low-ranking member of the Irish gang, he makes a name for himself in prison by routinely betraying one gang for another. He seals Jeremiah Cloutier in a wall to die a slow and painful death in response to the latter casting Kirk out of his gang for his erratic behavior. After Father Mukada refuses to accept Kirk's reversion to Catholicism, Kirk responds by burning down Mukada's church in hopes of killing him. When Mukada survives the attack, Kirk continues to hound him with absurd allegations of sexual molestation. Kirk, by now facing execution, is simply happy that he might die knowing that the allegations could see Mukada permanently stripped of his priesthood.
    • "The Truth and Nothing But..." through "Legs": Malcolm "Snake" Coyle, a member of the Homeboys, is a sociopathic murderer with no regard for human life. Originally imprisoned for armed robbery, Coyle's dark secret was revealed when he sadistically admitted to Augustus Hill that he murdered an Italian-American family one night for fun, while his friend recorded it on a videotape. First, as we see in flashbacks, he slit the mother's throat, proceeded to rape her dying corpse, then murdered the baby when the cries of fear started to get on his nerves. After Hill snitches on Warden Leo Glynn about Coyle's crimes, the other gangs, including the Aryans, disgusted by Coyle's crimes, unanimously agree to protect Hill from the Homeboys. Coyle's eventual death is mourned by none and he stands out as one of the few inmates in the series with no redeeming qualities.
