History Monster / Batman

* Abattoir, real name Arnold Etkar, born Arnold Etchison, is a psychopathic, prolific murderer 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 [[ComicBook/{{Knightfall}} broken out by Bane]]. After killing a family, he goes after his cousin Graham, hijacking a [[BusFullOfInnocents bus]] Graham and 12 orphans are on, planning to kill them all. Batman saves them, but Abattoir escapes, kidnapping the child of [[Characters/BatmanClayface Clayface III and Lady Clayface]] to force them to help him. Abattoir eventually kidnaps Graham, and places him in a sadistic DeathTrap, which eventually results in Graham suffering an agonizing, hours-long death. Even as a spirit, his evil lives on; in [[Characters/{{Azrael}} Jean-Paul Valley]]'s old armor, he tries to induce a miscarriage in his niece to possess the unborn baby's body.

''ComicBook/{{Batman}}'''s {{Long Runner|s}} status and the [[Characters/BatmanRoguesGallery massive size]] of his RoguesGallery mean that [[Characters/BatmanTheCharacter the Caped Crusader]], [[Characters/BatmanBatFamily and]] his [[Characters/BatmanSupportingCast allies]], have faced many foes. However, these stand out as [[CompleteMonster the worst of the worst]].

* ''ComicBook/CatwomanGuardianOfGotham'': [[Characters/BatmanTheCharacter Batman himself]], [[AdaptationalVillainy Bruce Wayne]], is a [[AxCrazy completely homicidal maniac]], who commits horrible deeds simply because he can. [[TeensAreMonsters As a teenager]], Batman gunned down two innocent people to steal their jewelry, leaving the young [[Characters/CatwomanSelinaKyle Selina Kyle]] orphaned. In his adult years, Batman begins murdering criminals all over Gotham, to eliminate any competition for his crime spree, during which he steals and murders to his heart's content. In his public persona of Bruce Wayne, Batman seduces Selina Kyle, and manipulates her into marrying him, at which point he murders Kyle's best friend before attempting the same on her, gleefully mocking her about how easy it was to manipulate her.

*** The [[EvilGenius Ultra-Humanite]] attacks the Metropolis World's Fair with a giant robot in 1939, intending to kill civilians until he gets $1 million. After he is stopped, he takes Lois Lane as his hostage until Batman and Superman find his lair. He reveals that he has set the Hyperglobe to blow up Metropolis, but Batman and Superman stop him. Though seemingly killed, it is later revealed he has swapped brains with Lex Luthor. Years later, he exposes Lois's unborn son, Joel, to Gold Kryptonite, rendering him powerless, and [[ManipulativeBastard manipulates him]] into believing that Superman stripped him of his powers. In 1979, Joel and the Ultra-Humanite attack the wedding of Bruce Wayne Jr. and Supergirl, leading to the deaths of Supergirl and Lois. Hours later, Joel also dies, because the concoction from the Humanite that gave him superpowers is ultimately fatal. In 1989, when Superman tracks him down, the Ultra-Humanite reveals he had several of his close friends and family murdered and plans to [[GrandTheftMe swap brains with Superman]] to gain his powers. When Superman stops him, it is revealed that the Ultra-Humanite has made it appear that Superman killed him in cold blood out of spite for Superman.

* ''ComicBook/SupermanSpeedingBullets'': [[Characters/SupermanLexLuthor Lex Luthor]] himself becomes [[Characters/BatmanTheJoker the Joker]] in this alternate retelling of Clark Kent and Bruce Wayne's backstories. A [[CorruptCorporateExecutive powerful, amoral businessman]] disfigured in an accident, Luthor is the one responsible for the death of the Waynes in this continuity, executing the burglars he sent to do the job afterward. Violently possessive of Lois Lane, Luthor schemes to make her his own, intending her to be the queen of his own "Jokerania." To remold the city, Luthor sends mercenary armies to utterly devastate Gotham to remake it from the ground up [[InTheirOwnImage in his own image]], killing hundreds--to which Joker merely quips "[[ForTheEvulz why not?]]" when Batman furiously demands why so many have suffered for his convenience.

** [[Characters/SupermanBrainiacCharacter Brainiac]] is an alien cyborg who partners up with Lex Luthor in order to make sure that Superman is compliant with Luthor's regime. Holding the bottled city of Kandor hostage, Brainiac murders a Kryptonian family for every time that Superman refuses to follow their orders. In an attempt to publicly discredit superheroes, Brainiac attacks Metropolis and orders Superman to not fight back or he'll have all of Kandor destroyed. Brainiac proceeds to wail on Superman when he refuses to flee, and continues on his rampage. While he is eventually stopped by Superman's daughter Lara, Brainiac's assault ends up killing thousands of people, including Captain Marvel, Jimmy Olson, and Lois Lane. Lara travels to Brainiac's hideout to free the citizens of Kandor by pretending to surrender, but not before Brainiac attempts to turn her into his subservient slave. Driven by {{sadis|t}}m rather than his usual logic, Brainiac takes immense pleasure in the pain and suffering that he causes others.

** [[OmnicidalManiac Judge Death]] is the ArchEnemy of ComicBook/JudgeDredd and, much like his original counterpart, presented as a psychopath who believes life itself is a crime deserving of death. Having kicked off his mission to purge the universe of all life by slaughtering his entire home world, Death arrives in Gotham in ''Judgement on Gotham'' to continue his bloody rampage, killing numerous people before being stopped by Batman. Escaping in ethereal form, Death allies with the Master of Fear, Scarecrow, and, after failing to betray and murder the man when [[YouHaveOutlivedYourUsefulness he outlives his usefulness]], teams up with him in massacring a rock concert of dozens of people in grotesque ways, planning to move onto the rest of Gotham afterwards. Later allying with the Joker in ''Die Laughing'', Death turns him into a [[Characters/JudgeDreddDarkJudges Dark Judge]] and proceeds to butcher thousands of people in Mega City One, and is stopped only after wiping out an entire amusement park of adults and children. With a love of killing and a philosophy to enable it, Judge Death is truly the worst foe in [[Characters/JudgeDreddTheCharacter Dredd]]'s [[RoguesGallery enemy line-up]].

* ''ComicBook/{{Joker}}'': The titular [[Characters/BatmanTheJoker Joker]] is once again presented as a [[AxCrazy madman]] bent on creating as much chaos and destruction as possible. Managing to get himself be released from Arkham Asylum, the Joker immediately began rebuilding his criminal empire. Starting off by skinning a former member of his gang for allowing Joker's influence in Gotham to crumble while he was gone, Joker forced "[[Characters/BatmanThePenguin Abner]]" to work for him by threatening to feed him to Killer Croc. As his next move Joker goes to slaughter countless criminals and mob bosses to get himself to the top of Gotham's underground. Starting a [[MobWar gang war]] with Two-Face, Joker murdered all of his henchmen, afterwards raping the wife of one of his closest men, Johnny Frost, because Johnny lied to him. Deciding to have some "fun", Joker begins to murder innocent people, at one point invading the apartment of peaceful old couple and [[WouldHarmASenior brutally killing them]] for no reason.

Deposed to Planet Qward by Batman and the Guardians of the Universe, Sinestro then developed a personal vendetta against Batman. Gaining the power of the yellow ring from one of the aliens from Planet Qward, he then infiltrates Gotham's police station to gain more information of Batman's past life and murders the Commissioner, James Gordon, in order to get rid of the witness. After gaining the information, he then murders the wife of Batman's parents' killer, Joe Chill, and then absorbs Joe's mind. He also turns the two acquaintances of Batman into his minions and then destroys several planets in order to incriminate Batman. Sinestro also attacks the Batcave in order to tamper with Batman's power source which resulted on Batman's butler, Alfred, becoming mortally wounded.

Mistreating and tormenting his patients, he has possession of the monstrous Laughing Man that he uses to kill anyone inconvenient. Arkham sends the Laughing Man to murder First Eschevin Gord-son, and later has Dirk Gray-son killed as well. Upon Bruss Wayn-son discovering his schemes, Arkham has him thrown to his seeming death and attempts to have Gord-son's daughter Barbara murdered. Keeping and torturing countless souls in his asylum, Arkham intends on eventually spreading his works to all of [[Franchise/{{Superman}} Metropolis]] to "cure" them.

He hires Catwoman to gather information on Kingpin, seeming making plans to usurp Kingpin's position as New York's reigning crime lord. [[Characters/DaredevilMattMurdock Daredevil]] and Batman team up to stop one of Scarecrow's trucks that was supposed to be delivering guns, but find it is full of bombs instead, with Scarecrow intending to kill Batman and Daredevil, along with the men driving the van. Scarecrow arrives in New York and uses his fear gas to force some of Kingpin's men to work for him. Scarecrow then begins a reign of terror having his men shoot up a restaurant, blow up a jewelry store, set fire to a night club and murder people in gangland killings. However, Daredevil and Batman soon discover Scarecrow's real plan: From the Statue of Liberty, Scarecrow plans to [[SupernaturalFearInducer spread his fear gas]] across New York, leading to untold death and suffering.

** [[Characters/CarnageCletusKasady Cletus "Carnage" Kasady]], much like his mainstream counterpart, is a [[SerialKiller 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 [[CardCarryingVillain rejoiced in his "black heart" and depravity]], and who wanted nothing more than to [[OmnicidalManiac butcher every thing in sight]].
