Vampires

Vampires are undead Cryptids that are featured heavily in Season 19. They subsist on human blood and can go feral if they don't drink for an extended period of time. Like most Cryptids, they are capable of disguising themselves as regular humans and can switch between their human form and vampire form at will.

Appearance
Vampires, for the most part, look like normal humans, although they often sprout fangs when in their vampire form. Starving vampires often develop pale and corpse-like skin, as seen in "The Pursuit of Normalcy" when Charlie refuses to drink blood. This condition disappears almost as soon as they feed.

Behavior
A human becomes a vampire when they are bitten by another vampire and partially drained of blood. The bite victim will then "die," with all vital functions ceasing. Unlike regular death, this state is merely a "hibernation period," which can last upwards of three days. Upon resurrecting, the new, "fledgling" vampire is the "hungriest that they will ever be" and can risk going feral if they don't feed within one day.

Fully developed vampires must consume human blood to survive, although how often they need to feed isn't entirely clear. In "Fights, Bites, and Elevator Lights," it seems that Nik started experiencing uncontrollable cravings roughly a week after running out of blood, although he didn't enter the corpse-skinned phase of vampire starvation. No foodstuffs other than human blood can sustain vampires, as everything else lacks sufficient nutrient value and "tastes like ash," with the notable exception of vodka.

Unlike ghosts, although undead, vampires still sleep. As seen with the handmade "coffin" in "Down to Film Noir," it seems as though they mostly sleep standing up and in enclosed spaces, although why this is the case isn't clear.

Strengths

 * Super-Strength: Vampires possess enhanced strength, almost on par with werewolves, as seen in "Fights Bites and Elevator Lights," when Nik swats Wyly across the room.
 * Teleportation: Vampires are capable of moving from place to place very quickly without being seen, a skill that Nik regularly shows off. Whether this is instant teleportation or some sort of super-speed, is unclear.
 * Immortality: Vampires benefit from unnaturally extended lifespans. The only known way of killing a vampire is to stake them through the heart and decapitate their corpse.

Weaknesses

 * Garlic: Garlic acts as a sort of vampire equivalent to chloroform, and even the smell of it is able to knock a vampire unconscious. This is evidenced by Nik using it to incapacitate Charlie in "The Pursuit of Normalcy," as well as the NBN's use of it in non-lethal ketamine darts. Garlic does not seem capable of killing vampires.
 * Daylight: This is likely vampires' most inconsistent weakness. In general, direct sunlight seems to cause them discomfort, but, like garlic, is incapable of killing them. Nik is shown to be able to walk around comfortably during the day as long as he's wearing adequate sun protection, including an umbrella and sunglasses. However, in "Down to Film Noir," Lars went outside during the day without any protection whatsoever and didn't show any discomfort at all (although he may have simply been too hungry to care). The only vampire who exhibited a particularly violent reaction to sunlight was Charlie, although this possibly could have been because of her fledgling status.
 * Running Water: Vampires are incapable of crossing running water and attempting to do so burns them.
 * Stakes and Decapitation: As explained in a leaked "suspect profile" for Nikolai, the only way to kill a vampire is to stake the heart and decapitate the body.

Notable Vampires

 * Nikolai
 * Charlie

Notes and Trivia

 * In "The Pursuit of Normalcy," Daisy complains that there are "almost as many vampires are pokemon." Whether the type of vampire shown in Season 19 is the only real kind, or if they're only one "breed" of vampires is unknown.
 * The only vampire consistently shown with fangs is Charlie. Nikolai has them for a couple of scenes, but due to recurring issues with the actor's fake teeth, he mostly goes without them. Lars is never shown with fangs, as his actor was a last-minute casting and there was no time to cast any to his teeth.
