Vampire (Pureblood)

Vampire (Pureblood) (バンパイア (血統書付), Banpaia (Kettōsho Tsuki)) was a Demon level Mysterious Being of the Monster Association.

Appearance
Pureblood is a vampire monster with slanted eyes, pointy teeth and light colored hair combed back and long sideburns reaching his chest. His attire consists of black pants, a gray double breasted vest with two chains, puffed shoulders, a ruffed collar, and a white shirt. Over this, he dons a long black cape.

Personality
Pureblood is a cruel, merciless, and arrogant vampire that came from a ancient bloodline of vampires. Due to his noble upbringing, he views all the monsters around him with disdain and hates being around them. He will often target weaker monsters of the Monster Association as food sources. Because of this violent attitude, several monsters viewed him with disdain, and many of them watched the battle between Pureblood and Zombieman and were prepared to eliminate Pureblood if he defeated Zombieman and was in a weakened state for them to exploit.

Monster Raid Arc
Pureblood and many other monsters from the association all attacked random cities simultaneously. Pureblood quickly massacres a good portion of the population of V-City.

Monster Association Arc
Pureblood is shown at the Monster Association base, where he sucks another monster dry while conversing with a turtle-like Mysterious Being. After that, he proclaims that he cowers before Orochi only to defeat the Hero Association and he is truly the most powerful monster, since he is the descendant of ancient vampire lineage. He is mildly annoyed by Devil Long Hair, who states he got his monster transformation from grooming his long hair, something Pureblood finds ridiculous.

He, along with the rest of the monsters, prepare to fight the intruders when the Hero Association attacks. Some time later, when other monsters are fighting Zombieman, the monsters guide them to a room, where Pureblood is hanging from the ceiling. The other monsters crowd in, eager to see which one of them survive and planning to feast on the weakened victor. Zombieman asks why all of the other monsters are planning to gang up on Pureblood, and he responds by saying they're envious of his power. Pureblood states his intention to kill the other monsters when he's done, and asks Zombieman who he is. Zombieman begins an introduction, but quickly draws his two pistols and fires at Pureblood. However, the vampire managed to appear behind Zombieman and bites on his carotid artery. Surprisingly, Pureblood recoils, disgusted by the hero's terrible tasting blood. Zombieman gets back on his feet, while Pureblood, believing Zombieman to be using the last of his strength to stand, regales the hero with his history as the strongest, and only, natural monster in the Monster Association, being a part of a hereditary lineage of vampires. Zombieman reloads his pistols with more powerful bullets and fires at Pureblood, although the force of the ammo manages to break both of Zombieman's arms. Pureblood throws the bullets back at Zombieman, although he's surprised when he sees Zombieman still standing. He realizes that Zombieman is the undying S-class hero he'd heard of. The fight resumes, but Pureblood quickly finds his own regeneration outmatched by Zombieman's. Thirty minutes later, Zombieman stands victoriously over Pureblood's bloody corpse with dead bats lying all around. The dying vampire is shocked and confused at how the hero managed to still stand, even after he'd killed him so many times. Zombieman tells the unresponsive Pureblood that he gave him about two hundred lethal wounds.

Abilities and Powers
As a Demon-level Mysterious Being of the Monster Association, Pureblood is an extremely powerful being. It took Zombieman, an S-class hero, about 30 minutes to defeat him, with the hero noting that Pureblood gave Zombieman about 200 lethal wounds that would take about 3 minutes to completely recover. The hero also noted he was the strongest monster he fought in a while. Pureblood, by his own account, is the strongest natural monster in the Monster Association due to his ancient vampire lineage.

Physical Abilities
 Immense Strength: Pureblood is strong enough to easily rip apart a human body as well as a monster's body, and given his status as a Demon-level monster, he is a naturally strong being. He is also strong enough to throw the bullets he catches from Zombieman's Desert Eagle with enough velocity to pierce his brain.

Immense Speed: Pureblood is fast enough to easily catch bullets and rip vital organs from a humans body before they can notice. He was also able to outpace S-class hero Zombieman several times during their battle.

Blood Consumption: As a vampire, Pureblood has a natural affinity for draining and metabolizing the hemoglobin of other sentient creatures for sustenance. This is not limited to human beings, but other monsters as well. He often targets weaker monsters of the Monster Association to drain their blood.

Regeneration: Pureblood is capable of regenerating from wounds by consuming blood. However, his power has a limit since if he doesn't have access to enough blood to regenerate, he will succumb to his injuries as shown when he runs out of enough monsters to supply him enough blood to keep up with Zombieman's regeneration.

Transformation: Pureblood can freely transform his body into a colony of vampire bats, which can attack as a swarm. He also can transform a sleeve of his clothes into a sharp blade.

Trivia

 * Pureblood is the only monster so far that has an established lineage, being part of a family of monsters rather than a completely unique first-generation monster like most Mysterious Beings.
