Yeeeeeesh...
- The vampires being in Gotham is terrifying enough, but the threat proves so great that Batman, normally a Badass Normal capable of taking on even a Physical God like Superman, is forced to sacrifice his very humanity and become a half-vampire himself in order to stand any chance of defeating Dracula (although this can be justified as this Batman is relatively early in his career as he hasn't even recruited Robin yet).
- Dracula himself is presented as a terrifying threat; according to Tanya, he usually stayed ahead of her and her Others by operating under the radar, but he makes his presence more significant in Gotham as though he no longer cares about getting caught, which he attributes to the tainted blood of the modern world driving him over the edge.
- The final battle between Dracula and Batman, the bat-monster that Dracula can become effortlessly holding Batman back even with his enhanced strength, silver batarangs and bat-like wings. Although Dracula is able to drink the last of Batman's blood during their fight, transforming him into a true vampire, the Dark Knight is able to kill Dracula by stabbing him in the neck with silver batarangs and impaling the master vampire on a tree before he 'dies' of bloodloss.
- The whole concept of Bloodstorm, as Joker takes control of the few remaining vampires in Gotham as his new gang while Batman tries to keep the vampires' numbers down even as he struggles against his new thirst for blood. Typically one of Batman's greatest assets is his strength of will, helping him to resist most methods of brainwashing, but his thirst for blood becomes so all-consuming that he ultimately declares himself "a junkie [..] addicted to that which [he's] never even tasted".
- Joker's death; when he kills Catwoman, Batman's already-faltering self-control finally snaps. He chases down Joker and Joker frantically runs into a church full of crucifixes, believing Batman is unable to enter the room. Batman not only proves him wrong, but he also tears into him with animalistic rage. He breaks Joker's neck then drinks his blood, snapping out of it just in time to drive a stake into the clown's heart to prevent him from coming back before he flees the church.
- Crimson Mist reveals that vampires must be decapitated after being staked. Suggesting that if Joker didn't die before Batman drank his blood, then vampire Joker could be a whole new level of evil. Fortunately, this idea has never come to light.
- Batman's description of his state at the opening of Crimson Mist, trapped in a state of living death where he is only aware of his body's decay and his own descent into insanity, paralysed by the stake in his heart but still potentially "aware" as his head remains.
- As if that wasn't bad enough, a re-read of Red Rain reveals that it's possible even Dracula wasn't aware of this "quirk" of vampire biology, as he reacts as though the vampires who have just been shot with crossbows by Tanya and her followers are explicitly dead when his return to the crypt after his stand-off with Batman shows at least two bodies with their heads still attached. Granted, it's possible that those vampires staked in Wayne Manor were killed in the sunlight when the house was destroyed, but that still leaves various vampires stuck in a state of living death in the sewers, needing only someone to come along and pull out the arrows to start another vampiric wave of terror in Gotham, this time without Batman to stop it...
- The villains have become a lot darker since Batman came back in Crimson Mist.
- Poison Ivy's death may be tame when compared to the other examples, but, it's just as scary. The flowers die around him as he approaches her and she's begging him to stay away. In a way, it sounds a bit like a rape scene. With Batman saying how Ivy's always wanted him but he can only have her in this form, where he is subject to dark and decayed corruption, at the same time Ivy is terrified and saying how she never wanted him "like this".
- Scarecrow decorates his costume with the fingers of his victims. Batman even regards Scarecrow as worse than him, as he chooses to kill innocents, whereas Batman has to kill but has enough self-control to target criminals and prevent the spread of his curse.
- Penguin kills a police officer by impaling him through the head with his umbrella.
- Riddler has been selling drugs by storing them in corpses, one of which is a university student.
- Killer Croc, in particular, is especially horrible since he's a blatant man-eating sewer predator in this incarnation. His opening scene is him pulling a woman into the sewer and devouring her flesh, then describing what she just ate in detail as he eats her stomach. Worse still, he's seen as a lesser of two evils compared to the vampiric Batman.
- Batman killing Black Mask and his goons. Two particular scenes stand out, he decapitates a goon and carries the head (and spine) in his maw. The second being that Batman impaled the heads on the Blackgate prison fence, to warn the inmates of his wrath.
- Killer Croc dies when Batman impales him with a stone pillar and Two-Face is killed when Batman stabs him in the head with two crossbow bolts, quipping "one for each face".
- On the same note, the way Batman had killed each criminal is brutal, as he decapitates Scarecrow after crushing his hand and kills the other criminals by tearing their throats out with his teeth. Not only that, he decapitates each victim to prevent them from coming back as vampires.
- Batman assaulting Arkham Asylum and murdering each helpless inmate within their cell. He even sends a note to the head doctor, written in blood and within the mouth of a severed head. Even though the rogues gallery had it coming, this is the moment where Commissioner Gordon believes that the hero of Gotham has truly become an irredeemable monster.
- Batman being a vampire makes him a tragic version of a Nightmare Fuel Station Attendant. The reason why Batman has been driven to madness is that Alfred and Commissioner Gordon neglected to cut off his head after they staked his heart, leaving him trapped in a tomb with an insatiable hunger and awareness of his decaying mind and body. When Alfred releases him, Batman is emaciated and driven mad by his lust for blood. He has enough self-awareness to steer himself away from harming innocents but is afraid of losing the rest of his sanity and becoming worse than Dracula. This concludes with him threatening to kill Jim Gordon, usually his closest friend, driving Gordon to set off explosive charges planted in the Batcave to let in the sun and stop Batman for good before he finally starts to drink from innocents.
