* EliteMooks: Their Combat Experts, who fight similarly to the League of Assassins. The final pair of Brutes you fight [[spoiler:at GCPD]] have all the equipment Brutes have had so far: shields, blades, and electro-gauntlets which they can switch at will. And in several predator encounters, minigunners, who can't be taken down silently.

* TragicVillain: All of the infected are incredibly dangerous only because they happened to get the wrong blood transfusion. Not only that, but the condition is eating away at their brains: in an interview tape, Batman compares their disease to [[https://en.wikipedia.org/wiki/Creutzfeldt-Jakob_disease Creutzfeldt–Jakob disease]]. When discussing about them with Gordon, he desribes the disease as a mutated strain of CJD.[[note]]In real life, CJD typically kills within 8-12 months, and yet [[spoiler: Batman shows up alive and well in ''VideoGame/SuicideSquadKillTheJusticeLeague'' which takes place 5 years after ''Knight.''[[/note]]

* AllForNothing: [[spoiler:Much like the real Creutzfeldt-Jakob Disease, the Joker Infection is incurable. Not that it matters as the victims all end up getting shot in the head.]]
* AxCrazy: Everyone except for Henry. [[spoiler:At first, anyway.]]

* ColorCodedEyes: Everyone suffering from the effects of the disease has begun to gain green irises. [[spoiler:Henry's begin to glow after a certain point, and it's how he learns Batman is infected as well.]]

* GoryDiscretionShot: [[spoiler:Albert/Johnny[[note]]Depending who you take down last[[/note]]]] is killed with a single gunshot, but the focus on the camera at the time is on his killer and the gun used. [[spoiler: Henry's suicide has the same treatment.]]
* KilledOffScreen: [[spoiler:Christina and Johnny/Albert by Henry, depending who of the latter two you decide to go after first. The other is technically an example, but fits more into GoryDiscretionShot.]]

* ShaggyDogStory: Batman has been searching for a cure for them and had hoped Henry's immunity would be the key in finding one that he kept him imprisoned for months. [[spoiler:However, ultimately, Henry was just as infected as the other three, meaning all the effort to find a cure was for naught. The Joker hallucination even lampshades this.]]

* ThereCanBeOnlyOne: [[spoiler:Henry murders the others, believing them to be inferior and not worthy of the Joker mantle. When he realizes Batman is infected, he kills himself convinced Batman is/will be the superior version of the Joker.]]

* TragicVillain: All of the infected are incredibly dangerous only because they happened to get the wrong blood transfusion. Not only that, but the condition is eating away at their brains: Batman diagnoses their disease as a mutated strain of [[https://en.wikipedia.org/wiki/Creutzfeldt-Jakob_disease Creutzfeldt–Jakob disease]].

* EvenEvilHasStandards: Despite bekng a SerialKiller cult leader, and much like the other vilains, even he finds Professor Pyg disturbing, asking Pyg from which hellish pit he comes from.

* ThrowingYourSwordAlwaysWorks: During the boss fight with him, he attacks by throwing multiple meat cleavers at Batman. His bio even states he's a skilled knife thrower.

* FeelNoPain: Which makes them unique from every other generic mook. Batman partially relies on the sheer pain of his attacks to cripple and incapacitate his enemies. The Dollotrons are so psychologically demolished they're incapable of experiencing pain, allowing them to tank through all of Batman's attacks unless he directly knocks them out.
* InformedAttribute: Despite Pyg supposedly making them immune to any sort of pain, the Dollotrons are very much subject to GameplayAndStorySegregation, as they can be taken down like any common mook.

** He never [[spoilered:revealed Batman's secret identity to Scarecrow or any of his militia, and is notably careful to never say Bruce's name when they might hear him.]]

** Played straight with the militia's army of drone tanks; despite claiming to know Batman's methods and that he doesn't kill people, the Knight never employs any manned artillery against him, only drones. If his tanks had human pilots, Batman's options against them would be much more limited since he likely wouldn't use the Batmobile's weapons against them.

* {{Expy}}: Potentially the closest thing the ''Arkham'' series has to [[VideoGame/BioShock Dr. Steinman]], given the very similar nature of his side quest.

** Special mention goes to the mook that distracts Batman by pretending to be the Arkham Knight in a car chase. After he's caught and Batman catches onto the decoy he starts with the usual 'you'll never stop us' sort of speech when Batman tries interrogating him. Then Batman starts remotely controlling the Batmobile and presses the back tire against the mook's head, making him squeal and beg him not to crush his skull. After that he quickly holds and gives Batman the info he needs to know.

** The militia have gear to scramble his Detective Mode scanner and detect when he's using it to pinpoint his location, they have medics to revive unconscious allies to get them back in the fight, and they'll use incendiary grenades in floor grates to flush Batman out if they suspect he's hiding in them. This makes them altogether [[ArtificialBrilliance a much more effective and competent force]] than the {{Mook}}s of previous games.

** He also never [[spoiler: calls Batman "Bruce" when his soldiers are present.]]

[[folder:Deacon Blackfire]]
!!Deacon (Joseph) Blackfire
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/decon.png]]
[[caption-width-right:350: ''"I've faced death more times than you can possibly imagine! I'll still be here when you're dead and gone, Batman. Gotham will be mine."'']]
->'''Voiced by:''' Creator/MarcWorden [[labelnote:Other voice actors]]Jean-Pascal Quilichini (Fr), Vittorio Bestoso (It)[[/labelnote]]

'''Joseph Blackfire''' is the insane leader of an underground religious cult within Gotham, whose fanatical devotees help him carry out ritualized, Old Testament-like human sacrifices. Jack Ryder, eager for broadcasting glory, gets too close during his investigative news report on the sect's doings, and Batman must save him from becoming the latest offering on their slab.

!!Provides examples of:
* AdaptationDeviation: The comics Blackfire was clean-shaven, had white hair, and didn't sport tattoos. This version sports a beard, gray hair, and tattoos.
* AdaptationalUgliness: While he wasn't exactly a looker in ''Batman: Cult'', Blackfire there was muscular, clean-looking, reasonably well-dressed, clean-shaven, and had a square jaw and a full head of white hair. Here, the deacon is an emaciated, filthy, balding, gray-haired old vagabond with ragged clothes and a ratty beard.
* AdaptationalWimp: In [[ComicBook/BatmanTheCult his famous story]], he was an intensely charismatic and intelligent leader who managed to amass an army capable of capturing and brainwashing Batman, and completely taking over Gotham. After breaking free from the brainwashing, Batman was left so [[BreakTheBadass broken]] by the experience he seriously considered hanging up the cowl and leaving the city to Blackfire. In this one, he's taken out in a few minutes and comes across more as a raving lunatic than a conniving schemer.
* BeardOfEvil: Unlike the comics, where he's clean shaven, this version has a UsefulNotes/RasputinTheMadMonk style beard.
* BloodBath: Repeated ritual sacrifice keeps him young.
* DarkMessiah: Claims his is the only path to salvation from Gotham's coming tribulation.
* EarlyBirdCameo: Mentioned obliquely in ''Origins'' as running a homeless mission, but not given a genuine appearance until ''Knight''.
* FauxAffablyEvil: Blackfire comports himself as a kindly man of God, with a lot of charisma and a folksy Southern accent, but the reality is that he's a self-righteous cult leader and SerialKiller.
* LongLived: Blackfire claims to be, variously, over hundreds or thousands of years old, and there actually exists hard evidence to confirm it -- one charge on his police file is dated to the 1920s, though assumed to be a mistake. Miagani tribal legends even speak of a similarly named man who murdered their chief, was shot with arrows, and trapped in a cave to die, but was found by Dutch colonists before he perished.
* MaybeMagicMaybeMundane: There are records of preachers and other holy men calling themselves Blackfire that go back to before Gotham was fully settled. Probably just a coincidence... right?
* MessyHair: In addition to his BeardOfEvil, he has long, dirty hair braided in dreadlocks and tied in a ponytail.
* RuleOfSymbolism: In the GCPD holding cell, he leans against the wall with his arms spread in a crucifixion pose.
* SerialKiller: Murdered a lot of people to possibly retain his youth.
* SinisterMinister: Styles himself as merely a thundering, fire-and-brimstone Christian preacher, but the truth is far darker.
* TattooedCrook: Has some rather ornate markings on his chest.
* WalkingShirtlessScene: Borderline example. He leaves his shirt unbuttoned to display his tattooed abdomen.

!!Man-Bat (Kirk Langstrom)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/41a62a370d46aef3b3967a41450666d3.JPG]]
->'''Voiced by:''' Creator/LorenLester [[labelnote:Other voice actors]]Thierry Kazazian (Fr), Federico Danti (It)[[/labelnote]]

'''Kirk Langstrom''' was a dedicated scientist who, along with his wife Francine, attempted to cure hearing loss altogether by splicing together the human genome with that of a vampire bat. The experiment had horrific side-effects, turning Kirk into a grotesque, nearly mindless bat[=/=]human hybrid who now stalks the skies over Gotham. After a run-in with the creature during the events of ''Arkham Knight'', Batman investigates the case, hoping for a potential cure.

!!Provides examples of:
* AdaptationalAngstUpgrade: [[spoiler: In this version of the story, Kirk accidentally killed Francine when he transformed. After returning to normal and finding this out he's reduced to weeping on the floor without solace.]] However, if you return to his lab, [[spoiler: someone has written the words "Forever my love" on the destroyed TV screen, and left a bloody handprint as well. Kirk's wife is known as She-Bat in the comics, and has similar abilities.]]
* AdaptationalLateAppearance: He's been part of Bruce's RoguesGallery since the 70s, and was an outright StarterVillain in the [=DCAU=]. Here, he makes his first appearance years into Batman's career -- [[spoiler:on the very last night of it, in fact.]]
* AdaptationalUgliness: The comics Man-Bat is a heavily stylized humanoid bat in most adaptations. Here, he's a painfully skinny humanoid monstrosity with only a few bat-like attributes. His exposed teeth and seemingly blind white eyes don't help.
* BatPeople: He was a scientist who attempted to splice human and vampire bat DNA together to create a cure for deafness, but instead accidentally turned himself into a monstrous bat/human hybrid with membranous arm-wings and large batlike ears on a distorted human face. His transformation rendered him largely mindless, and he now stalks the skies of Gotham as a feared predator.
* BodyHorror: Unlike most incarnations, in which he's essentially a heavily stylized anthropomorphic bat, the ''Knight'' version of Man-Bat looks like something out of a Creator/DavidCronenberg film, with an emaciated look that resembles a human with bat-like features.
* EasterEgg: If you've completed his side-mission, and set your system clock to October 31, 2015, Man-Bat will again give you a JumpScare, mirroring his introduction. When you return to GCPD, you'll discover he's escaped from his Isolation Chamber, the glass shattered, and has transformed once more.
* FreezeFrameBonus: That seagull-looking bird you occasionally see flying around in the distance? Zoom in, and you can tell that it's actually Man-Bat from it's legs and membranous wings. This can occur as early as when Batman leaves the Clock Tower the first time.
* FullFrontalAssault: Unlike other versions, this Man-Bat doesn't have MonsterModesty, which is clear when Batman pulls a naked, back-to-normal Langstrom out of the Batmobile. As Man-Bat, he also doesn't have anything below his waist, either.
* HappilyMarried: Was implied to have been this with Francine given how cheerful and happy they were in their recording. [[spoiler:Unfortunately, it ended tragically when Kirk became the Man-Bat and accidentally killed her. You can return to his lab to find Francine's body gone, with a glass window stained with blood reading "Forever my love" with a bloody handprint.]]
* JumpScare: His introduction occurs as Batman grapples onto a random roof or a [[https://youtu.be/gT3g28ej28s?t=249 skinny construction bar]] [[OffscreenTeleportation somehow]], whereupon Man-Bat peeks over the edge and screams in Batman's face before flying off.
* MayDecemberRomance: While it isn't clear how old Kirk and Francine are, with his male pattern baldness and graying hair, he looks at least a decade (or three) older than her.
* MistakenIdentity: A number of thugs and Militia soldiers can be heard conversing on spotting him as Man-Bat, often believing him to be Batman.
-->'''Mook''': Thought I saw Batman earlier. Guy's looking a lot hairier these days.
* MyGodWhatHaveIDone: [[spoiler:Upon learning he killed his wife as Man-Bat, Langstrom begins to weep helplessly, inconsolable.]]
* NoGoodDeedGoesUnpunished: Langstrom's work was meant to cure deafness permanently. It had the ghastly side-effect of turning him into a monstrous hybrid of man and bat.
* NonhumansLackAttributes: As noted before, this Man-Bat runs around naked and lacks genitalia.
* NonMaliciousMonster: Outside of his initial breakdown when he transformed, he isn't actively malicious. He's little more than a wild animal, flying around and attempting to stay free.
* OffscreenTeleportation: It's possible for him to suddenly appear on [[https://youtu.be/gT3g28ej28s?t=249 skinny construction bars]]. In real life, he would be easily spotted.
* ProfessorGuineaPig: A staple for this character. He experiments on himself to find the cure for his deafness.
* ShrinkingViolet: Langstrom was this in the recorded videos, being awkward in front of the camera and struggling to find the right words to announce his work, needing to be prompted and encouraged by his wife to remember not to use jargon.
* TransformationTrauma: Both of his changes into the monstrous Man-Bat and back to normal are extremely painful; in the first, recorded in the video of the experiment, Kirk destroys the laboratory off-screen in a fit of pain and unthinking anger. [[spoiler:Only later does he realize [[AccidentalMurder he killed Francine in his escape]]]]. When he's transformed back, it can be seen that he retains the scars from his transformation.
* TooDumbToLive: Batman himself [[LampshadeHanging lampshades]] that Kirk's decision to splice vampire bat DNA into his own was ''never'' going to end well.

[[folder:Professor Pyg]]
!!Professor Pyg (Lazlo Valentin)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/valentin_lazslo.jpg]]
[[caption-width-right:350:''"Pyg coming for you, Bat! Coming to make you perfeeeeeect!"'']]
->'''Voiced by:''' Creator/DwightSchultz [[labelnote:Other voice actors]]Serge Thiriet (Fr), Creator/PietroUbaldi (It)[[/labelnote]]

'''Lazlo Valentin''' was a gifted scientist who suffered a schizophrenic break, which caused him to develop a deranged new persona named '''Professor Pyg'''. Pyg formed the Circus of Strange, began to tour the country, and left a string of mysterious missing persons cases in the wake. An obsessive perfectionist, Pyg used identity-destroying drugs and invasive surgery on his victims to create a genderless lobotomized human known as Dollotrons.

* AdaptationalJobChange: Here, he's the leader of the Circus of Strange, rather than just a member of it.
* AffablyEvil: As psychotic as he is, he thinks he's doing the right thing, and acts accordingly. He's also pretty cordial to Batman when they first meet and even asks for friendship when he's locked up.
* AndIMustScream: The Dollotrons are revealed to be terrified when using detective vision, meaning he subjects those who survive his surgeries to this.
* AnimalMotifs: Pigs. In addition to his mask and nom de guerre, Pyg makes disgusting snorting noises while he speaks, his [[FatBastard physique]] and mangled face makes him resemble a pig even without the mask, and he uses butcher's knives as weapons.
* AntiVillain: As horrifying as he is, Lazlo is under the delusion he is doing the right thing, and at the end of the day is genuinely mentally ill and needs help.
* AxCrazy: Let's put it this way: In this world where villains were thrown into Arkham Asylum and left to rot, Pyg is one man who actually ''belongs'' there. The guy kidnaps people and surgically alters them to "make them perfect". He kills anyone that doesn't meet his standards, and when defeated, rants about how his "mother" won't be pleased that Batman stopped him. He doesn't seem to even have the basic understanding that he's done something wrong. Alfred and even [[spoiler:'''[[EvenEvilHasStandards Joker]]''']] admit he's likely worse than [[WretchedHive the rest of Gotham]] in that regard, and even Two Face seems disgusted by them being locked up in the same cell, outright calling him a freak.
-->'''Batman:''' [[{{Understatement}} You've got problems, Valentin.]]
* BlasphemousBoast: "Pyg is like clay. Pyg is like God! Pyg is here to fix us all."
* BodyHorror: The process to create his "Dollotrons" reeks of this to say the least. He's also a victim, considering that he also experimented on his own face, with the end result of part of it being mangled. Additionally, his SelfSurgery appears to have affected his respiratory system, given his constant snorting and a comment he drops to Batman in prison.
-->'''Pyg:''' Pyg wants a hug. Pyg wants to feel the nails in his chest!
* CallingCard: He blares opera music near his victims, which is how Batman and the cops find them.
* DreadfulMusician: Pyg's attempts to sing along to his favorite opera music reach a truly cringeworthy level of off-key.
* EvenEvilHasLovedOnes: Despite his... numerous flaws, Pyg has managed to father a child, Janosz[[note]]Who later takes up the mantle "Son of Pyg" in the comics[[/note]], whom he dotes on sickeningly, despite seemingly abandoning him in the wake of forming the Circus of the Strange.
* {{Expy}}: Potentially the closest thing the ''Arkham'' series has to [[VideoGame/BioShock Dr. Steinman]], given the very similar nature of his side quest.
* FatBastard: Pyg has a heavyset physique, although he's [[StoutStrength quite strong]] despite his heft.
* FateWorseThanDeath: What he subjects his victims to, becoming mindless dolls for the rest of their lives. Batman even says the trope word-for-word when calling out Lazlo for his actions. Disturbingly enough, Lazlo thinks he’s done them a favor.
* GollumMadeMeDoIt: Implies that he hears voices from "Mother" (or "Mother Goat") that urge him to carry out all his sick experiments.
* HatedByAll: Not only is he reviled by Batman and the GCPD for [[SerialKiller obvious reasons]], but [[EvenEvilHasStandards even the other villains in the game besides Joker and Deathstroke dislike him]], making it abundantly clear that even they think he's too crazy.
* HorrifyingTheHorror: The Joker thinks he's more depraved than "[Joker] 'n' Harley's honeymoon tapes".
* LargeHam: Puns aside, he stands out for being over-the-top with his mad operations and interactions with Batman. He even sings along to opera music and snorts like a pig while expressing his passion for his criminal activities.
* LaughablyEvil: When all is said and done, this guy is outright hilarious to watch, in no small part due to his hammy demeanor.
* LostLenore: One of his audio tapes has him muse over a lost love. Although it's difficult to interpret his ramblings, it sounds disturbingly like she was one of his first victims, a woman that he saw as perfect until his muse and tormentor Mother Goat "found her" and changed her into a hideous thing he had to fix -- which involved turning her into a Dollotron ''while she was pregnant with their child''.
* MadArtist: Like his comic counterpart, outright calling his creations art at one point. His direct methodology, however, is purely that of the MadDoctor.
* MadonnaWhoreComplex: Of the aesthetic kind -- as Pyg's obsessive mania grew, anyone who couldn't fit the impossible standard of perfection became a wretched mistake in need of correction, even the past lover he had once considered flawless. Despite his supposed surgical prowess, he will also kill and dispose of any victim that he discovers has physical abnormalities, injuries, distinguishing marks or pre-existing medical conditions, considering them hopeless cases that he can't fix.
-->"She was a beauty, Janosz -- a masterpiece, perfect in every way. Until Mother Goat found her. Imagine my horror when I emerged from that dreamy soup and discovered what she'd done. ''Placenta'' face, ''gorgon'' smile, ribbons of ruptured flesh. [...] Day and night I ''worked,'' month after month, sculpting her loathsome clay to recapture the beauty that saved me that night. The night of your creation. She ''clung'' to me as you grew, as I toiled to make ''her'' right again, but NOTHING PLEASED MOTHER GOAT! ''Nothing.'' I did all I could to fix her, to make her ''perfect...'' but by the time ''you'' came along, I couldn't even ''look'' upon that ''spoiled'' canvas of her face."
* TheMentallyDisturbed: Given [[AxCrazy his]] [[MadDoctor many]] [[PsychopathicManchild destructive]] [[ObliviouslyEvil behaviors]], he's a rare case of someone actually ''belonging'' in [[BedlamHouse Arkham Asylum]].
* MoodSwinger: '''''Oh Good God''''', this guy can swing from calm, to relaxed, to arrogant, to sad, ''all in one sentence''.
* ObliviouslyEvil: He doesn't seem to actually realize what he's doing is wrong, only that he will be [[PsychopathicManchild upsetting "mother"]] if he stops. He also goes on about making people "perfect" in a rather cheerful manner.
* ThePerfectionist: Pyg creates the Dollotrons because he can't stand the imperfections he perceives in people, believing that his horrific surgeries make them "perfect". The victims scattered around Gotham were killed because Pyg considered them too defective to become Dollotrons, essentially due to them not being a perfectly blank slate for him to work with.
* PsychopathicManchild: If his ranting about "mother" not being pleased with him during his VillainousBreakdown is any indication. [[note]]Said mother, whom he mentions showing to people before operations and is never seen in-game, is [[CargoCult a gigantic wooden frame covered in nails and barbed wire, topped with a blank staring mask]] in the comics.[[/note]] He also makes mention of a "Mother Goat" who destroys beauty as well, which is possibly Pyg's warped understanding of how the nature of Gotham wears people down.
* SelfSurgery: Did experimentation on his own face, which is a wrinkled mess as if he had too much plastic surgery. He also has stitching near his ears.
* SerialKiller: Killed about six people he considered too defective to work with in Gotham before Batman stopped him, and is implied to have traveled across the country doing much the same. It should be noted Lazlo isn’t looking to kill people, and most of the deaths were a result of not surviving the surgery. However, the six he has hung up throughout Gotham and written dismissive words next to ''were'' deliberately killed (according to Batman's scan of the first one, through deliberate overdose of sleeping drugs).
* ShiftingVoiceOfMadness: His insanity shows clearly in how his tone and demeanor can change not only from one sentence to the next, but from one ''word'' to the next.
* ShutUpKirk: When Batman calls him insane, Pyg retorts with, "And what are you?" [[VillainHasAPoint Considering Batman's worsening mental state, he may have a point there.]]
* SignatureSoundEffect: He often makes twisted snorts and squeals similar to those of a pig. It's unclear if this is because of his own preferential behavior or because [[BodyHorror his body is too mangled to breathe normally]].
* TalkativeLoon: Most notably in his audio logs, where Pyg can barely form a coherent sentence without resorting to colorful, opaque metaphors.
* ThirdPersonPerson: Almost insistently, along with not using any contractions or proper pronouns in reference to himself.
-->'''Pyg:''' Bad, bad, bad. Pyg is like clay! ''Pyg is like GOD!'' ''[Daintily]'' Pyg is here to fix us all.
* ThrowingYourSwordAlwaysWorks: During the boss fight with him, he attacks by throwing multiple meat cleavers at Batman. His bio even states he's a skilled knife thrower.
* TunelessSongOfMadness: He warbles a nasal, tone-deaf, mostly improvised duet with an opera record in his operating theater while carving up terrified victims.
* {{Ubermensch}}: What he's trying to create with his surgeries. For their part, his Dollotrons feel no pain. They also have no genitals.
* UncannyValley: Invoked with both his cracked, dingy pig mask and his appearance underneath it -- his features have been warped by constant self-administered facelifts and lip injections into a wrinkled, puckered, plastic-looking grimace, his hair is impeccably short and neat, and his bowtie is an incongruously cheerful shade of pink.
* VillainousBreakdown: Suffers a massive one when captured, crying about how Mother won't be pleased, and how he was so close to perfecting the dollotrons when Batman stopped him.
* WellIntentionedExtremist: From his viewpoint, anyway.
* WhatTheHellIsThatAccent: His severe delusional mania leaves his voice extremely inconsistent, with wild fluctuations in tone, volume and pronunciation.
* WickedCultured: Really has a thing for opera, though not very good opera, as Alfred considers the music he leaves behind to be very kitschy.
* WorstAid: Considers his brutal surgeries to be "healing" or "mercies".
* WouldHurtAChild: While all of his victims shown in the game are adults, one of the Gotham City Stories reveals that he once kidnapped a small boy, apparently for ransom, and ''still'' turned him and, presumably, the boy's father, into Dollotrons.

[[folder:Dollotrons]]
!!Dollotrons
-->'''Voiced by:''' N/A

'''Dollotrons''' are the unfortunate victims of Professor Pyg, rendered mute and machinelike through days of horrific mutilation and torture.

!!Provides examples of:
* AndIMustScream: They don't (and likely ''can't'') speak, but examining them in Detective Mode reveals that they're always terrified. The one Dollotron that does scream has his face covered with bandages and gauze, and is tearfully begging Pyg to stop what he's doing to them.
* BandagedFace: They all have swathes of gauze completely covering up their faces.
* BodyHorror: The surgeries and brainwashing from Professor Pyg have left them with heavy mutilation to make them identical with NoBiologicalSex or sense of pain.
* BrainwashedAndCrazy: They're so broken all they can do is attack on Pyg's command.
* FateWorseThanDeath: Pyg mentally destroyed them so much they're basically machines, incapable of expressing emotion, feeling pain, or speaking, uncontrollably twitching and, as Detective Mode reveals, [[AndIMustScream are truly terrified on the inside.]] After Pyg's defeat, Batman even names their state by this trope.
* FeelNoPain: Which makes them unique from every other generic mook. Batman partially relies on the sheer pain of his attacks to cripple and incapacitate his enemies. The Dollotrons are so psychologically demolished they're incapable of experiencing pain, allowing them to tank through all of Batman's attacks unless he directly knocks them out.
* InformedAttribute: Despite Pyg supposedly making them immune to any sort of pain, the Dollotrons are very much subject to GameplayAndStorySegregation, as they can be taken down like any common mook.
* NoBiologicalSex: Pyg made them all, both women and men, mentally and physically identical through surgery and brainwashing.
* TechnicallyLivingZombie: They're alive, but their minds and bodies have been mutilated so thoroughly that they might as well be walking corpses.
* TheVoiceless: As part of the procedure. The victim lying on the table when Batman arrives begs Pyg to stop his agony, but Pyg softly reassures him and exclaims "Here comes the choo-choo!"; afterward, he's seen with a bloody incision on his trachea, implying Pyg severed or cut out their larynx.
* WhatHappenedToTheMouse: The Dollotrons end up being placed in a jail cell after Batman apprehends Pyg, but they're all completely absent in the post-game. Presumably, they were [[KilledOffscreen euthanized off-screen]] [[MercyKill to end their suffering]].

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/batman_arkham_knight_20160313211143.jpg]]
->'''Voiced by:''' Creator/JenniferHale

Ra's al Ghul's younger daughter and Talia's sister. She appears in the Shadow War mission in ''The Season of Infamy'' DLC, leading a splinter faction against the League of Assassins.

* AdaptationalHeroism: Far nobler and more reasonable than her comics counterpart, who was basically Ra's with all the NobleDemon aspects removed.
* AgeLift: As mentioned above, in the game, she's Talia's younger sister. In the comics, it's the inverse: Nyssa is the older one and a Holocaust survivor, and Talia's mother first met Ra's at Woodstock.
* AntagonisticOffspring: From Ra's's perspective. Nyssa however sees her father as a decayed shell of a man wasted by endless revivals, barely more than a zombie. She feels that the League would be better served under her leadership.
* ChekhovsGunman: She's first mentioned in ''Origins'' after recovering data from a drone's memory card as an associate to Shiva, one of the eight assassins hired by Black Mask and a fellow member of the League of Assassins.
* FaceDeathWithDignity: In [[spoiler:the Cure option, Batman offers to save her with the remaining Lazarus chemicals after Ra's mortally wounds her, but Nyssa refuses to use it, preferring to die rather than stoop to her father's level.]]
* FieryRedhead: Her hair has a red tinge and she leads a rebel faction of the League of Assassins.
* IGaveMyWord: When Batman asks how he can trust her to take the League out of Gotham, she swears on Talia's grave. Should you help her, she makes good on it.
* ItIsDehumanizing: She outright refers to Ra's as a "thing."
* KickTheDog: [[spoiler: On the receiving end - saving Ra's will result in getting her killed.]]
* {{Ninja}}: Like the rest of her family she's been trained to fight, and even briefly spars with Batman if he choses to save Ra's. [[spoiler: Not good enough to save her from her father though.]]
* NotUsingTheZWord: Averted. She openly refers to her father as a zombie who should've died long ago.
* OnlySaneMan: Alfred notes this about her compared to her father and older sister.
* RenegadeSplinterFaction: She leads a breakaway group of the League of Assassins against her father's faction. In this case, the "renegade" faction is a good deal more reasonable than the main one.
* StrongFamilyResemblance: She looks a fair bit like her elder sister, albeit with shorter hair and harder features.
* TomboyAndGirlyGirl: Nyssa's chin length hair and practical clothes contrast Talia's [[LongHairIsFeminine long hair]] and form flattering uniform.
* TheUnfavorite: [[spoiler: A hidden tape reveals that Ra's had considered her weak and intended to leave the League to Talia if Batman refused to join them.]]
* VillainousValour: [[spoiler:How villainous she is depends on your perspective, but in the Cure option, she refuses Batman's offer to heal her wounds via Lazarus chemicals, saying that she welcomes death if only to prove she's not like her father.]]
* WhiteSheep: Alfred describes her as the most reasonable of her family.

!The Joker-Infected

[[folder:In General]]
!!Henry Adams, Albert King, Christina Bell, Johnny Charisma

After the Joker dies, Batman realizes that Joker's blood given to hospitals had been given to several patients through hospital error, despite Batman and the GCPD's best efforts to dispose of it. Prior to Scarecrow's takeover of Gotham, Commissioner Gordon came to visit the abandoned movie theater to find four people captured by Batman - the Joker Infected. Three of the gathered infected were showing signs of their affliction, but the last - Henry Adams - was apparently immune to the effects of Joker's blood, thus being the key to finding a cure. When Gordon realizes that there's an empty cell, Batman assures him that the last of the infected will be coming soon.

* AllForNothing: [[spoiler:Much like the real Creutzfeldt-Jakob Disease, the Joker Infection is incurable. Not that it matters as the victims all end up getting shot in the head.]]
* AxCrazy: Everyone except for Henry. [[spoiler:At first, anyway.]]
* BodyHorror: All of them, except for Henry, are turning into Joker in a revoltingly organic fashion. Christina and Johnny have lesions on their face similar to the Joker's Titan poisoning, and along with Albert King, they have paling skin with scabs across their body. Also, their mental degeneration is based on ''Creutzfeldt–Jakob'' - just to give you an idea of what's happening inside their heads...
* CanonForeigner: The group of them, owing to the fact that the Joker is still alive in the comics and has not attempted to spread himself like a disease. The closest there is comes from [[WesternAnimation/BatmanBeyondReturnOfTheJoker Joker Junior]].
* CloneByConversion: All of them are being mutated into clones of the Joker by the Joker's blood, except for Henry, who displays no symptoms of the condition.
* {{Clownification}}: After some of the Joker's Titan contaminated blood made its way into local blood banks, Henry Adams, Albert King, Christina Bell, and Johnny Charisma got some of the blood transfused into them when they got some routine medical procedures done, and were infected with a prion disease that, with the exception of Henry, made their skin turn a white bleached color, and gave them bright green eyes and hair, as well as a penchant for [[DarkComedy dark humor]] and [[MonsterClown murder]]. After capturing them, Batman held them so he could try and cure them, especially since Henry seemed resistant to the infection, [[spoiler: except that Henry's symptoms took longer to manifest and he also became a Joker clone]].
* ColorCodedEyes: Everyone suffering from the effects of the disease has begun to gain green irises. [[spoiler:Henry's begin to glow after a certain point, and it's how he learns Batman is infected as well.]]
* DecompositeCharacter: Each of them takes on an exacerbated version of one of Joker's traits, in addition to his sadism: Johnny gains his showmanship, Christina his obsession with Batman, Albert his brutality and Henry [[spoiler:his cunning. Batman himself seems to have picked up his ruthlessness.]]
* DemonicPossession: All of them were normal people until the Joker blood created dementia and breakdown of personality, slowly overwriting their minds.
* EarlyBirdCameo: If you're attentive you'll notice mention of them throughout Gotham, including "Have you seen me?" posters for Henry and Christina in the diner at the opening cutscene, an update screen informing people of Johnny's next show, and an ad for a prizefight featuring Albert King (cancelled).
* EvilHasABadSenseOfHumor: All of them (barring Albert, who's too much of a berserker for witty repartee) can crack some surprisingly nasty jokes, particularly Christina.
* FacialHorror: Both Christina and Johnny have slight lesions on their face, similar to the Joker's Titan poisoning.
* FauxAffablyEvil:
** Johnny Charisma is somewhat friendly in his interactions, although it's clearly just a front for his maniacal behavior, which is particularly evident when Gordon meets him.
** According to one of her former co-workers in the prologue, Christina Bell didn't immediately go insane after receiving the Joker's blood, but actually became ''friendlier'' for a time. Instead of being an aloof boss like normal, she began kindly asking about everyone's weekends and trying to get to know them... in order to see if they had an encounter with Batman so she could kill him.
** [[spoiler:Henry Adams would count as well, as he becomes very hostile once he drops the act.]]
* GoryDiscretionShot: [[spoiler:Albert/Johnny[[note]]Depending who you take down last[[/note]]]] is killed with a single gunshot, but the focus on the camera at the time is on his killer and the gun used. [[spoiler: Henry's suicide has the same treatment.]]
* KilledOffScreen: [[spoiler:Christina and Johnny/Albert by Henry, depending who of the latter two you decide to go after first. The other is technically an example, but fits more into GoryDiscretionShot.]]
* LaughablyEvil: Except for Albert King, all of them have some humorous traits.
* LegacyCharacter: They are essentially this to the Joker, and everyone has a different reaction to the discover: Batman sees them as the biggest possible threat if they escaped, his Joker hallucination sees them as inferior copies, Harley sees them as the closest thing to having the original Joker back, and the remaining characters are simply just scared of them due to their similarities to the Joker.
* LiteralSplitPersonality: All of those visibly infected have begun to take on different, exacerbated traits of the Joker; Christina gets his [[FoeRomanceSubtext obsession with Batman]], Johnny his [[EvilIsHammy theatrical flourishes]], and Albert his [[{{Sadist}} brutality]]. [[spoiler:Henry, it's later revealed, got [[DiabolicalMastermind his brilliant scheming]]. Batman himself seems to have gained ''his ruthlessness.'']]
* PracticallyJoker: An in-universe example, each [[DecompositeCharacter representing different aspects of the Joker's personality]].
* ReplacementGoldfish: Once Harley learns of their existence, she tries to kidnap them to replace her lost love, Mr. J.
* ShaggyDogStory: Batman has been searching for a cure for them and had hoped Henry's immunity would be the key in finding one that he kept him imprisoned for months. [[spoiler:However, ultimately, Henry was just as infected as the other three, meaning all the effort to find a cure was for naught. The Joker hallucination even lampshades this.]]
* SixthRangerTraitor: [[spoiler: The truth is that the last cell is for Batman himself, infected from the Joker's attempts to find a cure to his Titan poisoning almost a year ago. Despite being cured of the Titan side-effects, he still has Joker's blood and his disease. Despite that, he's trying to cure all of them.]]
* SlasherSmile: Being Joker, of course they'd have his murderous grin. [[spoiler: Henry reveals himself as infected by wiping his mouth with blood and giving a hideous grin even.]]
* TechnicianVersusPerformer: Johnny and Albert get into a spat after Christina is subdued. Johnny invites Batman to an innovative death trap, while Albert threatens to pound in Batman's face the old-fashioned way.
* ThereCanBeOnlyOne: [[spoiler:Henry murders the others, believing them to be inferior and not worthy of the Joker mantle. When he realizes Batman is infected, he kills himself convinced Batman is/will be the superior version of the Joker.]]
* TokenGoodTeammate: Henry Adams is the only Joker Infected who isn't murderous. [[spoiler: It turns out he's no different and ''Batman'' is the true token good teammate.]]
* TragicVillain: All of the infected are incredibly dangerous only because they happened to get the wrong blood transfusion. Not only that, but the condition is eating away at their brains: Batman diagnoses their disease as a mutated strain of [[https://en.wikipedia.org/wiki/Creutzfeldt-Jakob_disease Creutzfeldt–Jakob disease]].
* VillainousCrush: Christina and Johnny are very interested in Batman.

Highly respected principal of the esteemed [=McCallum=] Academy, Henry Adams was exposed to Joker's blood during a routine treatment at Gotham General. Displaying none of the symptoms experienced by the other victims, Henry's infection acts like an immunity that could be the key to developing a cure. Though initially cooperative, Henry's patience is wearing thin, and he's desperate to return home to his family.

* ArcVillain: [[spoiler: Of the infected blood subplot, taking the reins from Harley partway through.]]
* BeneathTheMask: [[spoiler:Henry slyly drops a few hints to his true nature as the game progresses -- such as innocently commenting that Batman's security system is easier to get through than he expected, for example -- but the most notable moment the mask almost slips is in an audio tape as he spots the other infected patients; acting terrified, [[ThereCanBeOnlyOne he angrily shouts that Batman should kill the rest of them]], as "it's the only way to be sure". Batman, disturbed, immediately cuts off the interview.]]
* BitchInSheepsClothing: [[spoiler:He acts like the only sane man, but he's really the ''worst'' out of all of them.]]
* TheCracker: [[spoiler:Trusted enough by Batman and Robin to be occasionally let out of containment to be tested for a cure, if not leave the room, he hacked the Batcomputer right under their nose.]]
* DiabolicalMastermind: With some hacking skills, [[spoiler: Henry allowed Harley to infiltrate the movie studio and secretly release the other Infected. He even managed to fool Batman, only revealing himself and manifesting his symptoms when the time was right.]]
* DrivenToSuicide: [[spoiler:When he sees he has the same green eyes as the other infected, he realizes that Batman makes a better replacement for the Joker and kills himself]].
* EvilAllAlong: [[spoiler:Henry tricked Batman, contacted Harley, freed the other infected and helped Batman gather them back up.]]
* EvilHasABadSenseOfHumor: [[spoiler: The "jokes" that he tells Harley are a sort of strange mix of the two versions. Not only are they sadistic and horrifying, they aren't even funny lacking even basic wordplay, and a far cry from the LaughablyEvil the Joker manages]].
* EvilOldFolks: [[spoiler:Initially pretends to be a kind old man, but it eventually becomes clear just how deranged he truly is]].
* FaceHeelTurn: [[spoiler:Originally seeming like an immune individual to the Joker Infection, he only shows his true colors right when he's about to off himself just to screw with everyone involved; ''even the other infected''.]]
* HopeSpot: [[spoiler: Because he is apparently sane, Henry symbolizes Batman's hope to eventually cure all of the Joker-Infected. This hope is cruelly dashed when he reveals himself to be just as insane as the others and kills them in a narcissistic desire to be the one and ''only'' Joker. Henry also becomes Harley's hope of getting the Joker back, only for ''her'' hope to be shattered as well when he shoots himself after realizing that Batman is infected too and could become a more powerful Joker.]]
* MadLove: [[spoiler: The tapes show that Henry has this with Harley. However, just like the Joker, he's not above threatening to kill her as a means of negotiation.]]
* MeaningfulName: When abbreviated, Henry Adams' initials spell out HA, which reflects his status as an infectee of the Joker.
* NiceGuy: He fears his wife must be worried sick, and just wants to go back to his family and school again. [[spoiler: Until you realize his true colors...]]
* RuleOfSymbolism: On a deeper, personal level, Henry Adams represents Batman's hope that the Joker could someday be cured of his insanity [[spoiler:and how futile this hope really is]].
* SadistTeacher: [[spoiler: After ditching the sheep's clothing, Principal Henry, a professor in biology, gives Batman a rough lesson in natural selection by killing the other infected.]]
* SelfDisposingVillain: [[spoiler:Upon noticing Batman's infection, Henry blows his own brains out, convinced that Batman will be a better Joker than all of the Infected.]]
* SomethingOnlyTheyWouldSay: [[spoiler:During their first meeting, Henry proves himself as the Joker to Harley Quinn by telling her the same sick, BlackComedy jokes the original Clown Prince of Crime was fond of.]]
* TokenGoodTeammate: Is the only Joker Infected to not be homicidal and is cooperative with Batman and Robin. [[spoiler: It's horrifically subverted when it turns out he was hiding his symptoms and reveals his true colors.]]
* VillainRespect: [[spoiler:The Joker, or at least Batman's (very accurate) hallucination of Joker, considers the other Joker-Infected to be washed-out inferiors compared to him. Not Henry, though; in fact, once he had revealed himself as the mastermind that hacked the defence systems, killed off the other Infected, and even taking Harley hostage to influence Batman, Joker briefly considers rooting for ''him'' instead of Batman as to which one would succeed him. Even then, Henry himself realizes that Batman is also infected, and would make the better successor]].

->'''Voiced by:''' Jules de Jongh [[labelnote:Other voice actors]]Sybille Tureau (Fr), Francesca Perilli (It)[[/labelnote]]

After a successful career of finance, Christina Bell joined the board of directors at Queen Industries in Star City. During a blood transfusion following a miscarriage, Christina was exposed to Joker's Titan-infected blood. When she returned to work, Christina took a knife to a board meeting, brutally murdered eleven senior executives, and carved smiles on her victims' faces. She adopted several facets of Joker's personality, notably his obsession with Batman.

* BadBoss: She quite clearly inherited this aspect of the Joker's personality. She constantly taunts Harley's men about how screwed they are and tells Batman to beat them bloody. A few of the Mooks comments she's actually ''worse'' than the Joker since he at least wanted them to win.
* BenevolentBoss: A bit of chatter from a woman who worked for her before she became infected indicates that she was a decent boss to have.
* DecoyDamsel: Pretends to be one... albeit badly. She's clearly planning to kill Batman and Robin after she's saved.
* FemmeFatalons: Christina has very sharp fingernails, and tries to claw Robin's face off with them.
* IJustShotMarvinInTheFace: Christina accidentally shoots one of Harley's goons while she's threatening a line-up of them not to disobey her, not that she's bothered by it. And since she's part-Joker, the rest of the goons just have to take it and obey her anyway. Given that she's basically ''the Joker'' it may not have been an accident.
* LargeHam: While not to the same extent as Johnny's theatricality, Jules de Jongh was clearly having a blast recording Christina's lines.
* MurderTheHypotenuse: The mere mention of Robin disgusts her, because she thinks Batman's focus on sidekicks and family distracts him from his most important and loving relationship, his feud with the Joker, and by proxy, herself. It's why when Batman and Robin move to capture her, she goes right for the latter first.
* PsychoKnifeNut: You'd think killing ten people at a Board of Director's meeting would require some sort of firearm, but according to the police report, she somehow managed to kill them with just a sharp object. And if that's not nutty enough, she proceeded to walk out the building with blood on her hands, while giving advise to some co-workers as if she didn't just murder a room full of people!
* ShoutOut: Her name seems to be a reference to Creator/ChristianBale, who played Batman himself in ''Film/TheDarkKnightTrilogy''.
* TheSmurfettePrinciple: The only one of the Joker-infected to be female.
* TragicVillain: All of the Joker infected are tragic, but this is especially apparent in Christina's case. While Albert and Henry received Joker's blood via routine medical procedure, and the exact circumstances of Johnny's transfusion are unknown, Christina received her transfusion after a ''miscarriage''. Makes it hard not to feel sorry for the poor girl.
* UnwantedRescue: She outright tells Harley's goons that she didn't want to be rescued... since it means being taken away from Batman.
* {{Yandere}}: Christina practically turns the subtext between the Joker and Batman into text. Lady's eager to be saved by Batman and eager to cut his throat in equal measure.

->'''Voiced by:''' Creator/MichaelRosenbaum [[labelnote:Other voice actors]]Jérémy Prévost (Fr), Alessandro Capra (It)[[/labelnote]]

Jonathan Browne, aka Johnny Charisma, made a name for himself on the cabaret circuit before he hit the big time when he was discovered by a national talent show. Charisma was no stranger to controversy with a string of drug offenses and a DUI, but his assault on a groupie was uncharacteristically violent. When he was infected, Charisma displayed signs of megalomania, with his behavior echoing the sadistic showmanship of the Joker.

* DreadfulMusician: Robin claims that Alfred sings better than Johnny does, in a tone that in no way suggests Alfred is a good singer at all. [[spoiler:The player never actually gets to hear how awful he is, since for Batman and therefore the player, Johnny is replaced by a hallucination of Joker singing instead.]]
* FanCommunityNicknames: In-universe, his fans are referred to as "Charismaniacs", which he brings up in a dialogue prompt. Considering Johnny's ego, it's very likely he created the nickname himself just to garner more publicity.
* GracefulLoser: [[spoiler: Surprisingly, yes. Once his bombs are all disarmed, he simply holds his mic up to Batman's face, asking "No encore?" with an awkward smile just before he gets knocked out.]]
* InformedFlaw: People find his singing voice horrible, but he is advertised on billboards around the city, which would be unlikely if he really was that bad. Remember however, that Joker's Titan poisoning made his voice raspy, so it's possible he suffers from the same problem.
* LargeHam: And ''how''. He's mentioned by Batman to have had an over-the-top personality before (he once even called himself "the messiah of entertainment"), but the infection has pushed his ego and showmanship to new heights.
* LoungeLizard: He's a professional cabaret singer, and he's got the looks, the fashion sense, the smarmy attitude and ([[InformedAttribute apparently]]) the pipes to fit.
* {{Narcissist}}: Even before his infection, Johnny had a pretty bloated opinion of his talents, deeming himself "the messiah of rock", and after, he shows signs of Joker's megalomania and self-promoting sense of showmanship.
* VillainSong: Implied, as [[spoiler:Joker overshadows him.]]

-->''"This is it! The fight of the century! You ready to get schooled, Bats? Where do you wanna start? How about getting your asses kicked 101?"''

Albert King, aka the Goliath, was a legendary prizefighter with consecutive knockouts since records began. Days before his testimonial fight, King checked into Gotham General for a routine procedure, only to become infected with Joker's mutated blood. After he hospitalized his entire family in a fit of rage, King took on the more violent and sadistic aspects of Joker's personality.

* AxCrazy: While all the Infected ([[spoiler:even Henry]]) qualify for this, Albert stands out, having ripped people's arms out of their sockets during his breakdown, and showing few aspects of Joker's personality other than his bloodlust.
* BadBoss: He picks up downed mooks and literally throws them back into the fight.
* TheBerserker: All of Joker's sadism and brutality in the body of a hulking boxer. Albert does little other than fight and boast about fighting.
* BloodKnight: Half his lines are about how much he loves to fight, even calling his showdown with Batman "the fight of the century".
* EvilSoundsDeep: Not surprisingly, considering that he has the same voice actor as [[Anime/{{Hellsing}} Incognito]], [[WesternAnimation/AvengersAssemble Thanos]], and ({{a|vertedTrope}} [[HeelFaceTurn reformed]]) [[VideoGame/StreetFighterIV Sagat]].
* {{Jerkass}}: Unlike the other Infected, Albert doesn't even pretend to like Batman, being as loud-mouthed and cruel as the real Joker, but with none of his humor or affected charm.
* LightningBruiser / MadeOfIron: Albert's a prize-winning heavyweight boxer, so it's little surprise that his boss battle combines immense strength, endurance, and deceptively quick reflexes for a man his size -- his regular punches are so hard that they can't be blocked, only dodged; zapping him with the REC, a gadget that stuns a typical Brute, doesn't even faze him; he can destroy your health bar with only a few hits; and the only way to hurt him, let alone knock him out, is through multiple Dual Team Takedowns. Even with Batman and Robin giving him a beatdown from both sides, he still furiously lunges out at them with wild, flailing hooks, something no other Brute or boss in the game, besides ''Croc'', can do.
* ScaryBlackMan: Like the Medics, he can bring unconscious goons back into the fight, but he rouses them by hauling them to their feet and yelling in their faces not to quit on him.
* SkeletonMotif: The patch of pale white spreading across Albert's face looks uncannily like a skull, and it's the icon used with the health bar in his boss fight.
* SuperStrength: Explicitly noted to be inhumanly strong, and his breakdown involved [[AnArmAndALeg ripping people's arms out of their sockets.]] Why he's so powerful isn't explained in the slightest, but due to his status as a former heavyweight champ, it's probably either a CharlesAtlasSuperpower, something to do with steroid use, or leftover Titan from Joker's blood.

* CrazyPrepared: He's debriefed his men with all his knowledge of Batman's tactics and gadgets, which is considerable, and prepared them to fight back with appropriate counter-measures. During their first face-to-face meeting, he makes sure to inform his troops that Batman's ChestInsignia is, in fact, ''not'' the weakest part of the Batsuit's armor. [[spoiler:Given that he was trained by Batman himself, who is famous for this trope, it's fair to say he taught Jason well.]]
** The militia are trained to watch for floor grates and have incindiary grenades to burn out the grates, they have scanners that can detect when Batman is using Detective Mode and can pinpoint his location (as well as scanners to scramble his Detective Mode), and the Medic variant of thug is able to revive unconscious enemies and get them back in the fight. This altogether makes them a [[ArtificialBrilliance smarter and more competent]] enemy force than {{Mook}}s in previous games.
** When Batman tries to pursue the Arkham Knight in a vehicle by tracking the Arkham Knight's voice, he ends up apprehending a Militia thug outfitted with a voice synthesizer to mimic the Knight's voice as a decoy.
** He frequently warns his men that Batman ''will'' upgrade his tech when he recognizes it's inadequate, and then when that happens, the Knight counters right back by rolling out improvements for his troops. Idle chatter among the militia frequently have them note that Batman is doing just what the Knight expected, and they think they're ready for him.

* HatedByAll: Not only is he reviled by Batman and the GCPD for [[SerialKiller obvious reasons]], but [[EvenEvilHasStandards even the other villains in the game besides Joker dislike him]], making it abundantly clear that even they think he's too crazy.

* HatedByAll: Not only is he reviled by Batman and the GCPD for [[SerialKiller obvious reasons]], but [[EvenEvilHasStandards even the other villains in the game dislike him]], making it abundantly clear that even they think he's too crazy.

* AxCrazy: Let's put it this way: In this world where villains were thrown into Arkham Asylum and left to rot, Pyg is one man who actually ''belongs'' there. The guy kidnaps people and surgically alters them to "make them perfect". He kills anyone that doesn't meet his standards, and when defeated, rants about how his "mother" won't be pleased that Batman stopped him. He doesn't seem to even have the basic understanding that he's done something wrong. Alfred and even [[spoiler:'''[[EvenEvilHasStandards Joker]]''']] admit he's likely worse than [[WretchedHive the rest of Gotham]] in that regard.

* DoesNotLikeShoes: He walks around barefoot in keeping with his vagrant cult leader look.

* DoesNotLikeShoes: She walks around barefoot.

The '''Arkham Knight''' is a new villain introduced in ''VideoGame/BatmanArkhamKnight''. Little is known about this mysterious new foe, apart from his name, except that he holds a great contempt for the Dark Knight and will do everything in his power to ensure the Batman's demise.

* MythologyGag: Arkham Knight's face mask comes in two layers: the black topmost one that changes his voice, and [[spoiler: a red face mask underneath that resembles the face mask of Jason's other alter ego, the Red Hood. Sure enough, when Jason finally abandons the Arkham Knight moniker and becomes Red Hood in the DLC, he retains the red mask.]]

** Special mention goes to the mook that distracts Batman by pretending to be the Arkham Knight in a car chase. After he’s caught and Batman catches onto the decoy he starts with the usual ‘you’ll never stop us’ sort of speech when Batman tries interrogating him. Then Batman starts remotely controlling the Batmobile and presses the back tire against the mook’s head, making him squeal and beg him not to crush his skull.

** This is especially apparent in Christina's case. While Albert and Henry received Joker's blood via routine medical procedure, and the exact circumstances of Johnny's transfusion are unknown, Christina received her transfusion after a ''miscarriage''. Makes it hard not to feel sorry for the poor girl.

** Special mention goes to the mook that distracts Batman by pretending to be the Arkham Knight in a car chase. After he’s caught and Bats catches onto the decoy he starts with the usual ‘you’ll never stop us’ sort of speech when Batman tries interrogating him. Then Batsy starts remotely controlling the Batmobile and presses the back tire against the mook’s head, making him squeal and beg him not to crush his skull. After that he folds faster than Superman in laundry day and gives Batman the info he needs to know.

* VillainousCrush: Christina and Johnny are very interested in Batsy.

** When Batman infiltrates his lair, the Arkham Knight ambushes Batman and shoots him in the side where his armor's weakest, then lets his men attack him while he's weakened. And when that doesn't work, he tries to finish Batman off with a tank. He even lampshades it.

* PrivateMilitaryContractors: They were established as an PMC by the Arkham Knight, having undertaken missions in South-America before brought over to Gotham.

* HorrifyingTheHorror: Joker, I repeat, '''JOKER''', thinks he's more depraved than "[Joker] 'n' Harley's honeymoon tapes".

* RevengeBeforeReason: His desire to see Batman dead interferes with Scarecrow's more well-thought-out plan. This is especially apparent in the [[spoiler:battle with the Cloudburst. He stays to fight as Batman slowly destroys his escort and damages the Couldburst itself, despite Scarecrow insisting he withdraw and save it]].
* RoaringRampageOfRevenge: What appears to be his motivation in trying to murder Batman and participate in Scarecrow's attack. He's even gone to the trouble in establishing a large PMC to aid him in destroying the Dark Knight.

* BadassBaritone: Courtesy of Creator/TroyBaker and the built in electronic modulator he has in his helmet. As mentioned below, the Arkham Knight sounds borderline demonic.

* FateWorseThanDeath: What he subjects his victims to. Becoming mindless dolls for the rest of their lives. Batman even says the trope word-for-word when calling out Lazlo for his actions. Disturbingly enough, Lazlo thinks he’s done them a favor.

* TheVoiceless: As part of the procedure. The one lying on the table when Batman arrives begs Pyg to stop its agony, but Pyg softly reassures it and exclaims "Here comes the choo-choo!"; afterward, it's seen with a bloody incision at its trachea, implying Pyg severed or cut out its larynx.
