"Humans, alien, has it not occurred to you I hold your lives in the palm of my hand? I, a god, decides when you will lose your lives, how much you will suffer, and how long you will bathe in the sweet agony of pain before you succumb to oblivion. I offer you one opportunity, bow at my feet…or forfeit your existence."

The DCU and related works based on DC Comics have been around since 1934 and have naturally inspired thousands of fan works. Given the source material, it's only natural that some of the villains are irredeemably evil.

Batman & Bat-Family

    Examples 
  • Arkham Patient Sessions: The Scarecrow, real name Dr. Jonathan Crane, is obsessed with causing fear in the masses. Inventing a fear gas, Crane proceeds to terrorize the people of Gotham City with hallucinations of their worst fears, committing murders along the way. When Batman captures Scarecrow, the latter spends his days psychologically tormenting the staff, including convincing an orderly to kill himself, while periodically fear-gassing people when he escapes. After fellow supervillain Dr. Death causes a mass breakout in Arkham Asylum, the Scarecrow kidnaps asylum director Jeremiah Arkham and locks him in the asylum's basement in order to drive him insane. Crane spends an extended amount of time drugging and torturing Arkham until he finally breaks, leading to his suicide. Afterwards, Crane escapes and spends a year terrorizing Gotham, culminating in destroying an entire neighborhood.
  • The Batman (link): The Riddler, Edward Nashton, is a Serial Killer who prefers murdering a parent and their child, leaving behind riddles for the police to solve for his next murders. Having killed Black Mask's wife by chopping off her legs and hanging his son, Riddler would go on to kill Jason Todd's mother and brother by making them inject poison into themselves. Later forcing Batman to solve a riddle to prevent the mayor's husband and daughter from dying, Riddler still has the husband murdered despite Batman solving his riddle, having Batman framed for his death. Capturing Bruce Wayne and his ex-girlfriend Julie Madison, Riddler has Bruce and three other rich men fight to the death to decide who's really Batman, threatening to drown Madison should they all refuse.
  • "The Batman Chronicles" (link): The Joker is the sadistic leader of the Red Hood gang, and is obsessed with making a name for himself. Having his men terrorize Gotham in a way that makes it seem random, at one point, Joker has a couple of men break into an empty warehouse in order to ambush and kill the officer sent to investigate. When one of his men reveals his identity to Batman, the Joker has him tortured and then shoots the man himself. The Joker and his men attack the GCPD, killing three people and kidnapping Commissioner Loeb, with the Joker personally torturing Loeb for information, even after Loeb agrees to cooperate.
  • Breaking You (link): Deathstroke is an assassin who has felt humiliated by his previous defeats by Batman and makes a deal with the Court of Owls to make Nightwing their apprentice, in which he plans to betray them by stealing Nightwing as his sole heir. He begins by physically assaulting Nightwing and later kidnapping Damien Wayne, putting the latter through torture in the process. Deathstroke later captures Nightwing and forces him whether to kill Damien or Tarantula, in which Deathstroke takes pleasure when Nightwing accidentally kills the latter through immolation. When the Bat-Family comes to rescue both of them, Deathstroke threatens to kill Batman and every Robin to punish Nightwing for his "disobedience".
  • City of Scars & Patient J: The Joker is once again portrayed as an irredeemably wicked monster. Considering himself the Arch-Enemy of Batman, the Joker has committed numerous atrocities just to torture his nemesis, from brutally beating the second Robin, Jason Todd, to death with a crowbar, to targeting Batman's best friend, James Gordon, by murdering the man's wife and paralyzing--and most likely raping--the man's daughter. In Patient J, the Joker is interviewed by a psychologist about his past crimes, all of which he recalls happily, and, when the psychologist begs the Joker to kill him to make himself famous, the Joker instead horrifically maims the man, leaving him alive just to torment him. After escaping from Arkham Asylum in City of Scars, leaving a nurse horrifically scarred in the process, the Joker kidnaps Councilman Johnson and his ten-year-old son, brutally murders the man's wife, then murders a man to steal his ice cream truck. After dousing Johnson with acid to kill him, the Joker plants a bomb on a carnival's ferris wheel, hoping to kill the dozens of children and adults in the surrounding area, before, as a final act of villainy, attempting to gun down Johnson's son. Always an attention-craving showman, the Joker views the mass populace as "puppets" for him to control in his ultimate comedy act, where the punchline is always death for his hundreds of victims.
  • The Gotham City Society of Fireproof Women:
    • David Cain was a member of the League of Assassins, assigned to the creation of "The One-Who-Is-All" as a bodyguard for Ra's al Ghul. Training his daughter Cassandra since birth to fulfill this role, Cain refused to teach her to read, write, or even speak; he instead taught her how to be the perfect weapon by murdering people in front of her. One of his favorite lessons involved shooting her in a non-vital area, and if she so much as flinched he would shoot her again. When Cassandra ran away after her first assassination at the age of nine, Cain would betray the League as he obsessively tried to hunt her down. Recruited years later by Harmonia, Cain assisted in creating distractions for Batman by massacring Black Mask's forces, later attempting to cause an international incident by assassinating a Kahndaqi diplomat. Cain taunts Cassandra for becoming "a faulty sword" under Batman's tutelage but runs for his life without hesitation in a fair fight, even threatening to shoot a hostage in a vain attempt to avoid defeat. He later tries to draw out Cassandra for a final match, threatening to kill thousands with bombs set around Gotham. Cain ultimately cares for nothing except securing his "immortality" through the creation of the perfect weapon.

Centuries ago she created the Army of Nemesis, an unstoppable force of evil that horrified the Olympians and caused Zeus to kill her. Possessing Harmonia in modern times, Nemesis hijacks her plan to destroy The Multiverse with the Army, inflicting Jason Todd with horrific visions of the Joker torturing him and forcing him to massacre a bar full of innocents after he raises his voice at her. Nemesis later tricks Wonder Woman into killing both her and Harmonia, activating the Army and sending them to destroy all life on earth so that the Olympians will starve to death, while the alternate versions of Harmonia throughout the multiverse will be eternally trapped in maddening insanity without the Army to end their pain. While her plan is foiled, the Army nevertheless manages to kill hundreds of innocents and four dozen heroes.
    • Motherland: Ra's al Ghul is the head of the League of Assassins, an organization dedicated to wiping out ninety percent of all human life in his egotistical desire to save the planet and rule the dwindled population. Killing thousands throughout the centuries in pursuit of his goal, Ra's seeks a male heir in the form of Batman, raising Astrid Arkham to believe Bruce murdered her mother so she'll kill all his friends and sever his ties to Gotham. Once Astrid is old enough to enact this plan, Ra's shifts focus, targeting Cassandra Wayne to become his bride and loosing Astrid to wreak havoc. Now seeking petty revenge on the city that foiled him time and time again, Ra's starts fires in the Amazon to draw out Poison Ivy, intending to use her to disperse Venom throughout Gotham so the populace will tear itself apart. Learning that he has an illegitimate granddaughter through Talia, Ra's also wipes out the entire town of Parisot in an attempt to rid himself of the potential usurper. Even after Cassandra sabotages his plan, Ra's tries to kill Bruce and Selina, revealing himself under his thin veneer of politeness to be a petty narcissist obsessed with continuing his lineage.
  • Gotham by Gaslight Fan Film Ripper (link): Jack the Ripper is a vicious serial killer stalking the streets of London.

The Joker fills the giant ball meant to commemorate the coming of a New Year with Joker Toxin, planning to drop it on the Square just as the clock strikes midnight and potentially kill the whole city. When The Question tries to distract him, the Joker shoots him and reveals he has a back-up plan to just the drop ball on the crowd of people if Batman stops the release of the toxin, before attempting to kill the Question with the toxin.
  • Nightwing fanfic Working Together (link): Catalina Flores, aka Tarantula III, keeps her canon crimes but not her redeeming traits. Returning to her old job in the FBI, Catalina kills 11 blond women by repeatedly stabbing them in the stomach and genitals just to create a case she could work on with her former mentor Richard "Dick" Grayson, aka Nightwing, who she raped 3 years ago and is obsessed with. Sexually assaulting and harassing Grayson as they work on the case together, Catalina fondly reminisces on the time where she raped him, and ultimately drugs him before raping him again, only refraining from kidnapping him because she knows Batman would hunt her down. Killing 3 cops and wounding 5 others when they try to stop her, Catalina also seduced two of her FBI colleagues in order to have them pressure Nightwing into taking the fall for her murders. Beneath her flirtatious, seductive behavior, Catalina is little more than an entitled, petty, and possessive madwoman who wants Nightwing to herself, caring little for the trauma she inflicted on her former mentor.
