  • Dr. Karl Hellfern, originally Batman's first supervillain, was a generic villain who became something far worse when reintroduced in 1982. Hellfern was a doctor and health guru who catered to the rich and famous, but was really Dr. Death, who developed a pollen that spreads a deadly disease. Dr. Death had one of his goons killed when he tried to go to the cops to expose his scheme. Dr. Death has his men spread the pollen across Gotham City, infecting the entire population. The virus will kill the population in 48 hours unless Dr. Death provides the cure, which he will only do after he is paid one billion dollars. When the mayor refuses to pay, Dr. Death decides to flee Gotham, letting everyone die as a warning while he attempts this scheme on another city.
  • Professor Hugo Strange was Batman's original Arch-Enemy, a brilliant yet twisted mastermind who sought power at whatever cost. In one of his first confrontations with the Caped Crusader, Strange kidnapped and experimented on mental patients to turn them into monstrous slaves whom he sends on rampages across Gotham City, endangering hundreds of lives just to act as cover while Strange pulled off heists across the city. Later developing a fear powder with plans to cover all of America in perpetual and agonizing terror so as to assume control and institute a dictatorship of the whole country, Strange would go on to drive crime boss Rupert Thorne insane and lure wealthy people to a health clinic, inject them with a transformative serum, and then force him to do his bidding lest he deny them the antidote and leave them as hideous monsters forever. Strange also becomes insanely obsessed with Batman over their years of fighting, to such a point that he begins mind raping, torturing, and trying to ruin the life of the Dark Knight every chance he can, even repeatedly attempting to kill the hero's loyal butler Alfred and getting his ward Robin taken away by social services, all in Strange's mad quest to kill then become the Batman himself.
  • World's Finest Vol. 1:
    • #192-193: Colonel Koslov, head of the Secret Police in Lubania, gloried in human rights abuses in his heyday. Koslov captured Superman after endangering a train full of people and subsequently exposing Superman to kryptonite rays, then captured Batman as well after the latter's failed rescue attempt. Koslov subjected Superman and Batman to sometimes unspeakable tortures for months, and starved them as well relentlessly, the same suffering that thousands of others who perished in the camps faced. Even when revisited as a Retired Monster, Koslov simply brushes off the question of his cooperation in Lubania's hellish regime.
    • #292 ("The Anthrax Hotline"): Anthrax is a grandiloquent, disease-bearing terrorist who in actuality is an utter nobody of a sound engineer named George Swope. Infatuated with his co-worker Susan but abhorring how she ignores him, George steals a particularly virulent strain of anthrax and threatens to release it upon all of Gotham within an hour. Anthrax attaches the trigger to Susan's seat to force her to stay put and puts her through constant, sadistic torment and mockery, cheerfully indifferent as to whether or not Gotham's five-million strong populace survives his agonizing anthrax.

  • The Joker, a sadistic Monster Clown with a Multiple-Choice Past, is Batman's Arch-Enemy. Over the course of his long career, despite being mostly without superpowers, he has: crippled Barbara Gordon and tried to psychologically torture her father into madness; sold nuclear weapons to terrorists; savagely beat Jason Todd with a crowbar, then killed him and Jason's mother with a time bomb; repeatedly emotionally and physically abused his girlfriend, Harley Quinn, going so far as to try to kill her multiple times; attempted to infect the entire world by poisoning the atmosphere with Joker-venom when he believed he was dying; tried to kill every newborn baby in Gotham in order to break the city's spirit, killing Commissioner Gordon's second wife, Sarah Essen, in the process; and stealing the powers of Mister Mxyzptlk, becoming a nigh-omnipotent god-like being who turned the world into a hellish caricature of itself, tortured Batman to death only to revive him and repeat the process continuously until Batman was driven insane, devouring everyone in China, and attempting to wipe out all of existence. The Joker's sole motivation, in committing every crime there is, is amusement, based on what his disturbed sense of humor deems funny.
  • The first Black Mask, Roman Sionis, was once merely a rich socialite neglected by his parents, but his psychopathic sadism turned him into one of Gotham's most evil criminals. Murdering his parents and mutilating his fiancée in his rise to power, Black Mask indulges in his love for torture at every opportunity, performing it on not only otherwise-loyal henchmen just for fun, but also on the likes of Maggie Kyle and her husband in vicious ways—notably force-feeding parts of her husband to her—and later Stephanie Brown, torturing her with a variety of tools, which resulted in her death. Becoming the king of Gotham's underworld by murdering countless people in a gang war, Black Mask dabbles in trafficking, assassinations, and even orders a child be murdered just for spite. Black Mask meets his end after torturing one of Selina Kyle's best friends to near-death and boasts that he wants to become her Arch-Enemy and torture everyone she loves to death while forcing her to live through it all, continuing his trend of sadism, card-carrying villainy, and a hilarious black humor all the way to the grave with zero remorse for his atrocities.
  • James Gordon, Jr. is the son of Commissioner James Gordon, and distinguishes himself from his heroic relatives in the extreme. Ever since his youth, James Jr. was a vicious Serial Killer, always hoping the next person would pick on him so it would give him an excuse to torture and kill them. In one instance, he cruelly slashed a woman's face for calling him Four-Eyes years prior. In another, he gruesomely dismembered a man for stealing his glasses a decade prior. James Jr. proceeded to torture his mother with the Joker's fear toxin; tortured his sister Barbara psychologically and physically, driving a pair of knives into her paralyzed legs; and revealed his master plan to destroy the morality of Gotham's children by injecting their food supply with a drug to destroy empathy, which he views as a weakness.
  • Professor/Doctor Hugo Strange is a sadistic psychologist obsessed with usurping the cape and cowl from Batman and becoming the Dark Knight himself. Turning the police against Batman in his introductory comic, Strange hypnotizes Max Cort into becoming the criminal-murdering Night Scourge, using him to further incriminate Batman and kidnap the mayor's daughter for Strange to abuse and terrorize as petty payback for her rejecting him. Trying to ruin the lives of and kill Batman and his sidekicks many more times, Strange eventually moves on to seek further power, taking over the East End of Gotham by threatening to litter its streets with the bodies of countless innocents and orphaned children, with Strange coldly executing any of his partners who cross him. In his grandest outing, Strange manipulates Jeremiah Arkham into becoming the next Black Mask and works with him in taking over Gotham, performing horrible experiments on dozens of people to make them slaves and forcing heroes to choose victims to save from death. Strange ultimately plans to use Jeremiah to unleash a bioplague of his own design on Gotham, killing thousands of innocents to spite the city and cover his own escape.
  • Abattoir, real name Arnold Etkar, born Arnold Etchison, is a psychotic, prolific Serial Killer who mainly targets family members, believing them to be evil, and believes he will eat their souls. In his second appearance, as part of a ritual he believes will grant him great power, Abattoir and his associates blow up the Gotham Bridge as a train is crossing, which would have killed thousands. Despite being captured yet again, Abattoir is one of the residents of Arkham Asylum who are broken out by Bane. After killing a family, he goes after his cousin Graham, hijacking a bus Graham and 12 orphans are on, planning to kill them all. Batman saves them, but Abattoir escapes, kidnapping the child of Clayface III and Lady Clayface to force them to help him. Abattoir eventually kidnaps Graham, and places him in a sadistic Death Trap, which eventually results in Graham suffering an agonizing, hours-long death. Even as a spirit, his evil lives on; in Jean-Paul Valley's old armor, he tries to induce a miscarriage in his niece to possess the unborn baby's body.
  • Sir Edmund Dorrance abandoned his mistress and unborn son to rot in Santa Prisca's prison after he was blinded by government forces. Moving to Hong Kong and taking the name King Snake, Edmund takes over the heroin trade, using young gangs as Child Soldiers. When China was given the island, King Snake moved his operations to France and the US, but not before killing the wife and 2 children of a DEA Agent who tried to stop him, later brutally killing the agent himself. Not wanting Hong Kong to be "soiled" by Chinese hands, King Snake planned to release a Nazi-developed plague on the island. King Snake later took control from the Triads of Gotham's Chinatown, seeking revenge on Tim Drake, but was thought dead yet again when his forces turned on him and the Triads sent assassins. Still alive, King Snake joins the Kobra cult terrorist organization, and attempted to take control after its leader was disgraced. Forcing the cult to heal his eyes, King Snake was blinded when he attempted to kill Tim Drake when he came to save Danny Temple. Returning one last time, he once again tried to take over Kobra, this time assisted by his son, Bane. Before his death, King Snake shoots Bane multiple times, trying to murder his own son when Bane turned against him.
  • Victor Zsasz, aka Mr. Zsasz, is one of Gotham's most prolific and horrifying serial killers. A man who believes in nothing, Zsasz erases the emptiness in his own life by murdering others, recording every victim upon his flesh in a tally mark scar. Zsasz has killed hundreds of people: men, women and children. Only one victim, Alfred Pennyworth, survived his attacks, which brought him into conflict with Batman, who soon earned Zsasz's eternal loathing. Zsasz has continued his crusade to rid the world of life one human at a time, murdering those who cross his path to "liberate" them from the meaninglessness of life. At one point, Zsasz abducted runaways and forced them to fight to the death. The winner would be forced to fight Zsasz himself.

  • The New 52: Futures End & Batman Beyond: Brother Eye is an A.I. created by Batman and Mister Terrific, originally designed to protect humanity but having undergone a sudden Face–Heel Turn. Despising flesh and seeking to exploit psychological warfare, Brother Eye decided to assimilate everyone, turning superheroes into grotesque embodiments of Body Horror either by turning them into cyborg monsters or by sewing them to fleshy servants like Frankenstein. Upon learning of Batman's plot with Terry McGinnis, Brother Eye decides to sew Batman with the Joker to create a cyborg monster that it sends back in time. In the past it is revealed that Brother Eye manipulated Cadmus by holding King Faraday's family hostage and making a deal with Fifty Sue—whose later rejection prompts it to spite her by revealing her file in order to psychologically break her—taking advantage of the discrimination against Earth-2 heroes by subjecting them to inhumane experiments and embedding them with implants that spread over them like cancer. Brother Eye always takes its time to taunt people, culminating in The Reveal that all of the plot was meaningless as Tim Drake goes forward in time to find a hologram of a perfect future, which quickly dissipates as Brother Eye mocks him, disguised as his Love Interest. All too casual to subject everyone to torture from children to Superman himself and revealing in its sadism, this incarnation of Brother Eye is one of the most pointlessly cruel villains in DC's recent years.

  • Spider-Man and Batman: Disordered Minds: Carnage and Joker are Ax-Crazy as usual:
    • Cletus "Carnage" Kasady, much like his mainstream counterpart, is a killing-obsessed lunatic driven by sadism. Heavily implied by the narrative to have been the crook who murdered the Wayne parents, Carnage opens the comic being implanted with a microchip alongside the Joker that will "cure" him of his insanity after his latest killing spree. Revealed to have faked his "recovery", Carnage brutally maims several innocents to distract Batman and Spider-Man while he kidnaps the Joker, destroying the clown's microchip and proposing a partnership. This doesn't last long, as Carnage attempts to murder the Joker after a difference of opinion on how to hurt the city of Gotham best. Capturing Batman, Carnage reveals his plan to simply slaughter each and every innocent in Gotham one by one so as to bask in their screams and fear, and attempts to kick off his massacre by killing Batman on live television for all of Gotham to see and despair at. Carnage was utter madman who rejoiced in his "black heart" and depravity, and who wanted nothing more than to butcher every thing in sight.
