An Elseworld trilogy that involves Franchise/{{Batman}} becoming a vampire. There are three parts to it:

!!Batman and Dracula: Red Rain
A bunch of deaths are occurring in Gotham where the victims are found drained of blood with their throats slashed. As it turns out, the slashes are to hide the puncture wounds from vampires. Between his time investigating, Batman has dreams of a woman appearing to him as mist and then materializing. As it turns out, she is a vampire named Tanya (later changed to half vampire) that has spent a good while turning other vamps away from real blood and towards fighting Dracula. She visits Batman in the night and secretly bites him, infecting him with the vampire virus without actually drinking from him, to give him the strength to defeat Dracula, and she later sacrifices herself to destroy Dracula's horde by drawing them into the batcave as Wayne Manor is destroyed to rain sunlight into the cave. Batman faces Dracula and defeats him, but at the cost of the last of his humanity as Dracula bites and drains him in the process.

Batman, with his new powers, continues to fight for Gotham. However, he begins to feel bloodlust and struggles with refraining from drinking anyone's blood. Cue ComicBook/TheJoker who steps in to boss Dracula's remaining {{mooks}} around. He begins a spree of killing Gotham's wealthier criminals and taking their belongings. Selina Kyle makes an appearance as a normal person, but is bitten and becomes a WereCat. She meets Batman and provides her company, which curbs his bloodlust. In a later fight with the Joker, she is killed, infuriating Batman. He succumbs to his bloodlust and sucks the Joker dry. Horrified by what he has done, Batman orders Gordon and Alfred to stake him.

!!Crimson Mist
Without its Dark Knight, Gotham has fallen prey to its villains. Fearing what may become, Alfred removes the stake from Batman, which, since he wasn't beheaded, allows for him to be revived. Now a vicious monster, however, Batman takes to the skies, killing all of his rogues. He then enters Arkham and kills every inmate. Gordon and Alfred decide to team up with Two-Face and Killer Croc to stop Batman. In the end [[spoiler:everybody dies.]]

Also apparently set in the ''Red Rain'' [[TheVerse Verse]], but not necessarily canon to the original trilogy, are "Red Rain: Blood Lust" in ''DC Infinite Halloween Special'', in which Batman kills the Graysons, and ''[[Comicbook/CountdownToFinalCrisis Countdown]] Presents: The Search for Ray Palmer: Red Rain'', in which the Challengers of Beyond meet [[ComicBook/{{Nightwing}} Dick Grayson]], Vampire Hunter, only for Batman to turn him into a vampiric ComicBook/{{Robin}}.

Elements of these story appeared in ''WesternAnimation/TheBatmanVsDracula'' and a version of this world is set in the ''VideoGame/InfiniteCrisis'' game.

Please only list Tropes that are unique to this particular Batman story. Tropes that already apply to Batman, such as TheCowl, don't go here.

!!Tropes used in the Batman Vampire trilogy
* AlternateUniverse: Before ''ComicBook/CrisisOnInfiniteEarths'', this world was listed as Earth-1191. Following ''InfiniteCrisis'' it's been designated as Earth-43. According to ''ComicBook/TheMultiversity'', Earth-43 is home to an entire Vampire Justice League, which implies Bruce had managed to turn Superman, Wonder Woman, and many other heroes.
* AndIMustScream: Batman's fate in-between Bloodstorm and Crimson Mist. As Batman was not [[OffWithHisHead decapitated]] after he was staked, he was only kept in a death-like state, fully conscious and aware of his body's decay and his rampant bloodlust. Needless to say, he's not pleased when Alfred removes the stake.
* AndShowItToYou: Selina tears out the heart of the vampire that turned her.
* AnyoneCanDie: [[spoiler:And they all do. Except for Dr. Arkham.]]
* ArrowCatch: Batman easily catches crossbow bolts fired at him by the Joker in ''Bloodstorm'' ([[spoiler:after Catwoman dies TakingTheBullet for him]]) and Two-Face in ''Crimson Mist''.
* ArtShift: Crimson Mist is smoothly colored, whereas the first two where inked.
* AxCrazy: By the time of ''Crimson Mist'', Batman has devolved into little more than a bloodthirsty monster who eagerly beheads his victims and drains them of blood. By the end of the story, he states that perhaps he's become an even bigger monster than ''Dracula himself''.
* TheBadGuyWins: In ''Bloodstorm'', Batman considers this the case after he [[spoiler: succumbs to his bloodlust and kills the Joker, reflecting that the Joker has finally turned Batman into a killer like himself]].
* BeePeople: In Bloodstorm, the remnants of Dracula's horde are unable to think beyond their next victim with their master's death... which helps the Joker to convince them to join him.
* BigNo: Both Batman and Alfred let out more than one over the course of the trilogy.
* BodyHorror: As a direct result of his body's decay in Crimson Mist, Batman is little more than a walking skeleton with [[RedEyesTakeWarning piercing red eyes]].
* CannotCrossRunningWater: In Bloodstorm, Selina escapes from a vampire by falling into a river.
* CatGirl: Selina Kyle becomes a were-cat in Bloodstorm after being bitten by a vampire in wolf form.
* CessationOfExistence: According to Dracula, this is the end result for someone who dies and doesn't turn into a vampire. Gordon refuses to believe it.
* ChildrenAreInnocent: To the extent that the mere sight of Dracula about to attack an innocent child allowed Tanya to break free of his control and escape.
* ContinuitySnarl: ''Crimson Mist'' states that stakes to the heart only incapacitates the vampire in a death-like state unless the head is also removed, whereas Dracula was completely dusted and KilledOffForReal after Batman ran him through on a splintered utility pole.
* CrapsackWorld: Gotham, as per usual. When Dracula comes to town, his murder spree goes largely unnoticed under its already high crime rate.
* {{Crossover}}: Between Batman and Dracula.
* CurbStompBattle: Batman and Dracula's fight. Batman finds himself unable to match Dracula's strength even with his own vampiric powers and relies on silver Batarangs to do any damage.
* DarkerAndEdgier: Invoked and Lampshaded with the Riddler, who has gone from extortion and robbery to drug trafficking and murder, combining the two by using a murder victim's body to store heroin. Within the work itself, both Bloodstorm and Crimson Mist are much darker than Red Rain, both ending on near-complete downers compared to Red Rain's BittersweetEnding.
* DeathSeeker: During one of his private monologues, Batman remarks that he isn't sure if he's killing people to sate his bloodlust or to provoke Gordon and Alfred into taking action against and killing him.
* DeathTrap: The Joker sets one up for Batman in the form of a church full of crosses. [[spoiler: Since Batman hasn't drank anybody's blood at that point, [[EpicFail it totally fails to work]].]]
* EmpoweredBadassNormal: Batman becomes one after being turned.
* EnemyMine: Two-Face and Killer Croc's gang join forces with Commissioner Gordon and Alfred to stop Batman in Crimson Mist. As soon as Batman appears to have been killed, Two-Face and Croc end the alliance and try to kill Gordon and Alfred.
* EvilCannotComprehendGood:
** As Batman becomes increasingly corrupted, he reflects that while once saw Tanya and Selina's {{Heroic Sacrifice}}s as noble, he now sees them as foolish.
** The Joker whines that Batman should have already gone on a killing spree ever since he became a vampire, failing to take his moral fibre into account.
* EvilIsPetty: The Scarecrow is shown stalking and killing the former {{Jerk Jock}}s who tormented him in high school.
* EvilMakesYouMonstrous: Batman in Crimson Mist barely resembles anything human.
* EvilerThanThou: Invoked. At the end of Crimson Mist, Batman remarks that he's become worse than criminals like Two-Face, perhaps even worse than Dracula himself.
* FallenHero: Batman by the time of Crimson Mist.
* {{Fingore}}: The Scarecrow decorates his costume with the severed fingers of his victims.
* GodzillaThreshold: Several during Crimson Mist:
** With crime running rampant throughout Gotham since Batman's staking, Alfred becomes so desperate to give the city a savior again that he removes the stake from Bats' body, reviving him. Sadly, Batman has been driven completely insane by his bloodlust and his body's decay, and embarks on a rampage, killing nearly all of Gotham's villains.
** After Batman kills most of his RoguesGallery, including the inmates of Arkham Asylum, Gordon agrees to an EnemyMine with Two-Face and Killer Croc to stop him.
* GoneHorriblyRight: Alfred revived Batman in Crimson Mist to give Gotham a savior and put an end to the crime wave. Batman does so... by killing all of Gotham's villains and draining them of their blood.
* GoodScarsEvilScars: The Riddler bears two noticeable question mark-shaped scars, one on his face and the other on his torso.
* GunsAreWorthless: Against vampires, anyway.
* HalfHumanHybrid: Of a sort. In Red Rain, Tanya bites Batman to infect him with vampirism while not actually drinking from him, thus giving Batman vampire powers while still remaining essentially human. He becomes a full vampire during the final showdown with Dracula.
* HeroicSacrifice: Selina and Tanya both sacrifice themselves to save Batman and stop Dracula, respectively, while Alfred willingly lets Batman drink from him to give him the strength needed to save Gordon from Two-Face.
* HonorBeforeReason: Gordon initially refuses to work with Two-Face because he's a crook. After Batman slaughters Black Mask's gang, mounts their heads on Blackgate Prison's fence as a warning to the prisoners inside, and then butchers all the inmates in Arkham Asylum, he changes his mind.
* HostileWeather: The red rain, which is acidic.
* IAmAHumanitarian: Killer Croc.
* IHateYouVampireDad: Tanya isn't exactly thankful to Dracula for vampirizing her.
* ImpaledWithExtremePrejudice:
** In Red Rain, Batman defeats Dracula by pushing him down onto a splintered utility pole.
** In Crimson Mist, he kills Killer Croc by running him through with a stalactite, and then sticks two crossbow bolts in either side of Two-Face's head.
* JokerImmunity: Averted.
* KillEmAll: In Crimson Mist, Batman has been so consumed by bloodlust and insanity that he makes it his duty to kill every last member of his RoguesGallery.
* MusclesAreMeaningless: Batman in Crimson Mist. He's little more than a skeleton, but easily overpowers Killer Croc in a straight-up fight.
* NeckSnap: During their confrontation, Batman punches Joker in the face with enough force to snap his neck, but this doesn't immediately kill him: Bats drains him dry.
* NiceJobBreakingItHero: Batman's rampage in Crimson Mist was all caused because Alfred has the bright idea to take the stake out of his corpse to deal with Gotham's massive crime wave.
** Under the circumstances--said massive crime wave in the absence of Batman or anyone else capable of curbing the tide of crime and sin--this could just as easily fall under GodzillaThreshold.
* OffWithHisHead: Apparently, the only way to permanently kill a vampire is to stake them and then chop their heads off, as revealed in Crimson Mist. After draining his victims, Batman always makes sure to take their heads so they won't come back as vamps.
* OurVampiresAreDifferent: The vampires are of the old-school style, being that Dracula is involved.
* PsychicAssistedSuicide: When Dracula first reveals himself to Batman and Tanya's pack, he [[CompellingVoice orders]] Tanya's pack to their knees, and then to stake themselves. Batman breaks the spell by attacking Dracula before they can carry out the latter.
* RedEyesTakeWarning: Batman's eyes turn red when his blood cravings flare up. In Crimson Mist, his eyes are permanently red.
* RoguesGallery: The most well known Batman foes are in it.
* SenselessSacrifice: [[spoiler: Alfred lets Batman drain him so he can be strong enough to save James Gordon from Two-Face and Killer Croc, but Gordon winds up getting killed almost immediately after anyway by falling rubble from the destroyed batcave.]]
* SuicideBySunlight: Done by both Tanya and [[spoiler: Batman himself.]]
* TakingTheBullet: Selina takes a crossbow bolt for Batman.
* ThatManIsDead:
** This line from the final panel of Red Rain:
-->'''Batman''': Bruce Wayne may be gone... but the Batman will go on... ''forever''.
** In Crimson Mist, everyone in the story, including Batman himself, openly acknowledge that Batman is no longer the man he was, because Batman, no matter what, [[ThouShaltNotKill would never take a human life]].
* ThePowerOfLove: Used by Selina to keep Bruce sane... [[spoiler: until the Joker kills her.]]
* UndyingLoyalty: Even after everything the corrupted Batman has done over the course of Crimson Mist, Alfred refuses to abandon or give up on him.
* VegetarianVampire: Tanya and her pack survive on a specially made artificial blood substitute. Batman initially survives on it as well, but his bloodlust soon overtakes it.
* WalkingWasteland: Only shown once, but in Crimson Mist, when Batman attacks Poison Ivy, his mere presence causes her plants to wither and die.
* WhatTheHellAreYou: Riddler asks Batman as such after shooting him has no effect. Batman's response:
-->'''Batman:''' "The answer to life's every riddle: death and hungry darkness."
* WingedHumanoid: Both Batman and Dracula manifest wings while transformed.
* YouCantGoHomeAgain: Near the end of Red Rain, Batman and Alfred sacrifice Wayne Manor and most of the Batcave to ensure the destruction of Dracula's horde and that Batman's SecretIdentity remains a secret.
