Vampires (吸血鬼 Kyūketsuki) are powerful sentient beings who are, physically, similar to humans. All known vampires are part of the Alucard Clan.
Vampires are creatures with extraordinarily long lifespans and unbelievable power. Each vampire has demonstrated the ability to use Magic, despite the fact that they have had seemingly not had any formal training. Rachel Alucard demonstrated her mastery of the ability to use Teleportation Magic when she still had the physical appearance of a 6 year old; not even Nine of the Ten Sages was capable of using Teleportation Magic at the level that Rachel demonstrated. All of the known vampires have demonstrated incredibly high life-force values. As demonstrated by Raquel Alucard, vampires have the ability to share their life-force with a bitten servant, however, this causes them to hover between life and death until a year has passed, and they become a vampire themselves.
As in legends, one of their weaknesses is the sunlight and only the strongest of their kind can freely walk under it. As such, their kingdom is located within the endless night that covers the Alucard Castle.
In his prime, Clavis Alucard was considered so powerful by the Mitsurugi Agency that they hired the Immortal Breakers to assassinate him. Clavis effortlessly shrugged off the attacks from the hired assassins, and later came to recruit one of them to serve as his butler years later after saving him; the former assassin in question is Valkenhayn R. Hellsing.
Their Drives mainly focus on control of the wind, and Clavis' existence is like a Drive itself since he is an Illusionary Creature. Like the stereotypical vampire found in various media, a simple bite from a vampire will turn the victim into a vampire themselves. Rachel tried this ability on Ragna the Bloodedge in the original timeline of BlazBlue, but it failed for some reason, and Raquel demonstrated it upon Naoto Kurogane in BlazBlue: Bloodedge Experience — Part 1, however, Naoto has a year until his transformation occurs. Anyone who transforms into a vampire via this method will have an insatiable appetite for blood, leading them to become berserk until their thirst is quenched.
Because of their limited numbers, vampires are hardly known about in the BlazBlue universe, with the only known clan being the Alucard Clan. Due to Rachel's status as the head of the clan, it can be inferred that more vampires exist than what is currently known.
