History time: In the original folklore, most vampires were short, ugly, Eastern European peasants. Then Polidori creates the character of Lord Ruthven and suddenly they're all elegant, English, aristocratic and look suspiciously like Lord Byron. Rymer's Varney the Vampire gives them fangs and the whole "wandering the world hating what they've become" thing. Then Sheridan Le Fanu's Carmilla was written, and vampires suddenly became alluring, bisexual upper-class gothic girls. Then, Dracula was written, and they're still elegant aristocrats, but moved back to Eastern Europe, sexy and deadly, outwardly beautiful yet disguising an inner corruption. Thus, horror turned to fetish, and pop culture... ahem... the world was never the same again. And we all know what happened since.
In the early 1920s, F.W. Murnau had a great idea. Since the German Expressionist movement was all about stylization, why not apply this to vampires? Why not create a vampire that looks exactly like what he is: a parasitic bloodsucker? And so, Nosferatu got made, and very nearly destroyed.
But Murnau's character, Orlok, played by scary-ass stage actor Max Schreck, has become one of the most iconic vampires ever, and has spawned a flock of imitators, typically used as a contrast to the elegant, pretty vampires, who for some reason are more likely to be treated sympathetically, or at least respectfully.
In order to qualify as a character who Looks Like Orlok, they must possess some combination of the following:
Count Chocula, the spokes-vampire for General Mills' chocolate/marshmallow cereal, isn't purely this trope — he has the Lugosian dark hair and widows's peak and tidy, aristocratic clothing, but he has the pointed ears, extra-long fingers with claw-like nails, narrow, hooked nose, and pointy little rat-fangs in place of his incisors rather than as canine teeth. He really owes more to Orlok than to Lugosi.
Anime and Manga
Hellsing, the antagonist Incognito's appearance seems to be based on that of Count Orlok. By contrast, Alucard is based on the more popular imagery of the suave Dracula. Then again, AlucardisDracula.
Black Cat gives us Preta Ghoul. He used to have hair, though, until it rotted out.
The lizard chimera Bido of Fullmetal Alchemist is completely bald (with a speckled head) and has the requisite pale skin, hooked nose and sharp teeth, and he furthers the similarity by the cloak he always wears, so he can hide from normal humans. Granted, he also has a rather large tail.
Abidani of Gamble Fish. He's a vindictive, macabre, sadistic character with a bald head, a very angular face, spindly limbs, a hooked nose, elf ears, a slight hunch and spiky teeth. This appearance was caused due to Abidani being nearly electrocuted to death by an electric chair as a young man.
In a Jhonen Vasquez comic, an angsty teenage boy desperately wishes to be made a real vampire— and his wish is granted by one. Instead of becoming a hip and stylish regent of the night, though, he gains a hideous form whose oversized bald cranium and tusk-like fangs only keep growing as he drinks blood. The final page shows him far into the future, with a head the size of a van, watching TV and thinking "That fucking vampire."
The Carnival Geek Cannibal version of The Vulture in Spider-Man: Noir is based on Orlok.
The vampire in the Cal McDonald miniseries Two Red Eyes is a homage Orlok and is known only by the name Nosferatu.
The Watchmen/DraculaFusion FicBram Stokers Ozymandias features a vampiric version of Adrian Veidt who looks a bit like this (though with pointed canines instead of incisors, a full head of hair even if it's a bit thin, and an age-related stoop rather than a real hump) before he regenerates to his handsome, canon form.
The Strangers from Dark City, while not as facially deformed as Orlock himself, do strongly give off the same impression with their pallor, baldness and eerie movements.
Riff-Raff from The Rocky Horror Picture Show was partly patterned after Orlok - dark overcoat, balding, thin features and a hunchback. Richard O'Brien would later play the creepy Orlok-alike Mister Hand in Dark City.
Werner Herzog's movie Nosferatu The Vampyre, staring Klaus Kinski, which is sort of a remake, keeps this character design, but changes Orlok's name back to Dracula.
Shadow of the Vampire: Willam Dafoe as Max Schreck playing Orlok, but he really looks like that because he really is a vampire.
The Reapers from Blade II, formed by a plague within the vampire community. The plague turns the sexy normal vampires into Orlok style monsters.
The vampires of 30 Days of Night are a successful balance of a Nosferatu-like vampire and the prevalent "pretty" vampire, so much so they seem to have sparked a revival of the former appearance. They have black pupils, pasty-white skin, claws, and shark-like teeth.
One of the running gags in the MSTing of Escape 2000 is that the main female character looks like Orlok.
The mutated vampires from Daybreakers seem to be heading in this direction. Lack of blood in their diet causes them to revert to a feral state indicated by loss of hair, bulbous head, elongated face, pointy ears, and growth of claws. Of course, these are accompanied by several non-Orlok characteristics like loss of higher brain function, and even arms devolving into wings in extreme cases.
In Van Helsing, Dracula and his wives all play out the One-Winged Angel trope and can transform from their good-looking normal appearance into bat monsters. In the case of Dracula himself, his "true form" is an Orlok-looking creature with bat wings.
The night-terror creatures in They have heads that Look Like Orlok, while their bodies are even more extreme in their bestial, spindly twistedness.
Timothy Spall's Peter Pettigrew in Harry Potter has elements of this, though he's only balding and he ditches the longcoat for a much-less-impressive cheap suit. He's The Renfield, and the character, like Orlock, is associated with rats, so it's kinda fitting.
Voldemort seems inspired a bit by the look of Orlok, only without a nose.
Severus Snape, everyone's favorite gaunt, pallid, hook-nosed recluse. (In fact, for a while, fans used to speculate that he was a vampire.) Instead of the trenchcoat, though, Snape chooses to wear a long black, batlike robe. And the movies kinda ditched this look when they hired Alan Rickman to play Snape.
Bob in The Discworld Reformed Vampyres' Diary 2003. Subversion in that, over the course of a series of notes between the Black Ribbon leader and the woman who plays the harmonium, it becomes apparent that he isn't actually a vampire at all.
The Master's appearance from The Strain is heavily influenced by Orlock.
Vampires in Night Watch look like this, when they shed their human disguise and reveal their true appearance.
The vrykoloi in The Bone Palace by Amanda Downum look rather like this; rather bestial, even the prettier ones, starving-thin, bat-like ears, animal fangs, light-sensitive eyes.
In the Laura Caxton novels, vampires have the bald head and pointy ear thing going on, and some let their fingernails grow long and claw-like. However, instead of two front teeth fangs, their whole mouths are full of row after row of sharp teeth, like a shark. Oh, and they're also albinos.
Concept art for the Yuuzhan Vong depicts them as this. One major difference is that instead of a hooked nose, they have no nose whatsoever. Their warriors at least are also very fit and athletic-looking.
Charlie Manx in NOS4A2 is described as looking like this although he's not a vampire in the traditional sense; instead, he maintains his youth by his car draining the souls of children as he kidnaps them to a semi-imaginary realm.
Not a vampire, but Ixion looks like this when he's introduced in the Fall of Ile-Rien trilogy. It later turns out that he's essentially possessing a magically-created clone of himself (the original Ixion having been killed shortly before the first book), and the reason he looks like he does is because a Gardier officer had him pulled out of the vat before he was done. The clone body stabilizes during the second book, and Ixion turns out to actually be moderately attractive, if somewhat into the Uncanny Valley.
The Master from Buffy the Vampire Slayer. The interesting thing is that the vampires in that world usually look like normal humans most of the time and then put on their vampiric Game Face when they're about to do some vampire shit. The Master is so old that he's now in permanent Looks-like-Orlok-mode, and the other vampires are pretty impressed by it.
The Turok-han ubervamps from the final season also followed the Orlok mould.
The Prince of Lies in Angel (episode "Why We Fight") is probably the most explicitly based on Orlok, with trademark pointed ears and long fingers. Like other Buffyverse examples, his appearance is credited to age.
The look of a horror character from a running sketch on The Fast Show was based on Orlok; he would emerge out of the night to awaken a young woman in black and white, but would answer her scream only with non sequiturish betting tips.
The League of Gentlemen contained a rare female example. Well, the character was female. But was played by a male actor.
While Sylar from Heroes certainly doesn't resemble Orlok himself, Nosferatu was an early inspiration for the character. While most of the original idea was changed, it is held over in his depiction in the prophetic paintings from first season. This is most obvious in Sylar's own rendition of himself posing as Nathan in that season's Bad Future, which featured long, taloned fingers. Also, he stole Orlok's coat.
One episode of The X-Files involved a brain-eating mutant with pale skin, jet-black eyes, and no ears.
Not an actual vampire, but Lx-3, the failed Lex clone in Smallville's tenth season premiere, "Lazarus" definitely has this going for him. Between the Bald of Evil, Pointy Ears, protruding front teeth, and grey, wrinkled skin he could easily pass for one of Orlok's relatives.
Many of the Nosferatu in game art took on this appearance in Vampire: The Masquerade, but it could differ quite a bit from the Orlokian norm, as long as it was hideous.
The version of the Nosferatu in Vampire: The Requiem could take on many forms foul and fair, but regardless of appearance always had an unsettling aura that made social interaction difficult.
The Necrarch bloodline in Warhammer Fantasy Battle.
The Strigoi even more so - giant mutated bloodsuckers that are barely human. By way of comparison, Necrarch vampires often resemble rotting corpses.
The Basic Dungeons & Dragons sourcebook GAZ3 The Principalities of Glantri had the vampire-like nosferatu monsters (inspired by Nosferatu), whose illustration looked like this.
The text didn't mention them looking weird or standing out in a crowd, however. Later appearances by Mystaran nosferatu show them passing for human, so it's probably artistic license.
D&D also has the Keepers, which are basically an Expy of the Strangers from Dark City.
The D&D third edition Ravenloft books introduced the Vrykolakas, a subtype of vampires that look like Orlok. They are specifically described as "night scavengers and plague-carriers" to play up Orlok's plague rat aspects. One key difference is that instead of fangs they have a long, barbed tongue.
The Deadlands TTRPG has the Nosferatu as a subspecies of vampires. They look like Orlok. And ride macabre trains when raiding for victims.
Some of the races of Talislanta look a bit like this, such as the Na-Ku cannibals, Marukans, and Nagra. Even the Kang might fit, if Max Schreck had gotten really ripped at the gym and suffered a bad sunburn.
Two examples in Castlevania: Olrox from Symphony of the Night (his name is a giveaway) and Brauner from Portrait of Ruin. It should be noted that while Brauner physically resembles Orlok, he dresses like the later, classier versions, making him a weird hybrid of the two designs.
In a more direct Shout-Out, Orlok himself is seen in the background of a stage in Castlevania Chronicles, frozen in a block of ice for some reason.
The Council's Vampyri in City of Heroes look like this, although they are not actual vampires. They are the result of a super-soldier program inherited from the 5th Column, which they overthrew. The highest-ranking of them is actually named Nosferatu.
Baraka from Mortal Kombat was visually based on an Orlok mask. The costume used for his first appearance in Mortal Kombat II was, in fact, an Orlok mask with silver-painted false fingernails added for his teeth.
Though Magus is often drawn as a Pretty Boy in Fan Art, and his sprite could be mistaken for one, his character portrait is basically Orlok with long, blue-white hair and red eyes.
Medeus from Fire Emblem: Shadow Dragon fits this despite being a dragon instead of a vampire. He's got the bald head, clawed hands, fangs, and batlike ears. All of these traits make him a dead ringer for the Count.
These appear as (low level) monsters in The Witcher alongside more traditional Vampires.
Vampires from the Legacy of Kain series go through a progression of appearance as they age; they start out fairly human-looking, develop into a more elven/bishonen form with talon-like nails, further evolve to gain more bestial traits like three-clawed hands and feet, and the really ancient ones like Kain and Vorador end up with a far more reptilian look.
There's a much more direct Orlok homage in Blood Omen 2. Marcus, one of the bosses, dresses in a voluminous black overcoat and has the requisite pale complexion, bald head, angular features, and spindly fingers.
Vampires in TRU-Life Adventures start out looking like themselves, but grow to resemble Orlok as they lose their humanity.
In Shadowgirls, a very Orlok-looking member of EoD was sent to eliminate a hospitalized cop. It 's a bit unclear if he was a vampire or something else, although the almost certainly wasn't human.
Although Count Chocula blended Dracula and Orlok as a cereal mascot, in Breakfast of the Gods, Brian Sanderson subtly played up the Orlokian aspects more. While he kept the elegant clothes and dark widow's peak, he's far more ratlike and sinister: his face is more pointed, his fangs are longer and more wedge-shaped, and his hands look more like the paws of a rat with long thin fingers and prominent knuckles.
At the end of the Graveyard Shift episode of Spongebob Squarepants, the lights start to flicker, and thinking that it's the Hash Slinging Slasher's doing, everyone looks over and is relieved to find that it was only that silly Nosferatu!
In the animated series School For Vampires the vampire kids' main teacher is based on Orlok's appearance. Somewhat subverted in that we see, through flashbacks, that he once had a long, flowing mane of blonde hair.
In episode 6 of Ugly Americans, Blake is a blatant Expy of Edward from Twilight, while Blake's father was obviously modeled after Orlok.
Mighty Max gives us Skullmaster, an ancient warrior-sorcerer with chalk-white skin, fangs, claws, and pointy ears (who's also very buff). His menacing voice was provided by Tim Curry.
