My vampires are the result of a human being given a good amount of their sire's blood, then being drained completely by their sire. The human dies for a few minutes before reanimating as a vampire. Vampires are immortal and supernaturally fast and strong, being able to move large distances in the blink of an eye and able to easily overpower the average human. I tend to like the idea of vampires being able to influence a human's actions or emotions with their gaze, but it's not an overpowering domination type of mind control. I call it "influence" because it just makes a human more susceptible to following the vampire's commands, but it would be extremely difficult to influence a human to do something that is strictly against their moral code, or do something like eat spiders if they have arachnophobia.

My vampires are usually greatly weakened by sunlight, if not outright immolated by it. They can be killed by having their heart pierced, being beheaded, or burned completely. A well-fed vampire can regenerate wounds very quickly and I even like the idea of being able to reattach severed limbs if the injured vampire gorges themselves on blood. Depending on how supernatural we want to go with vampires, I actually do like the trope of them being repelled by holy symbols as long as it's wielded by a person of that faith. So not just crosses, but the Star of David, or even a Pagan sigil.

A vampire will not die if they stop feeding on human blood, but they will dessicate slowly and experience excruciating pain/hunger until the point where they are essentially a mummy, trapped in their immobile body. I would imagine this would drive a vampire insane if they experienced being "locked in" like that for a long time.

The bite of a vampire can be excruciating, relaxing, or pleasurable, depending on the whims of the vampire doing the biting. I imagine this being an extension of a vampire's mind influence power. So if a vampire just didn't care to assuage their victim, then the human would feel the full pain of the bite as well as the very uncomfortable feeling of having their blood sucked out of their body. On the other hand, most times vampires can actually feed on humans with them not really noticing because they make it feel like getting a hickey (one that leaves you strangely tired afterward, but still). Then other times, the human can be flooded with feelings of euphoria, sometimes sexual excitement, sometimes just a feeling of bliss.

Vampire blood has regenerative properties when consumed by humans in some capacity, so a vampire could save a human from a mortal wound with enough of their blood. They could not help a human reattach their limbs with any amount of vampire blood, but the wound would close very fast and possibly allow for survival as long as the rate of healing outsped the loss of blood. Any injury that would cause immediate death to the human (i.e. direct gunshot to the head, huge hole in the chest, falling from a great height, etc.) could not be healed by consuming vampire blood, as it would require the human to still be alive to benefit.

One uncommon thing I like for my vampires is that there are two types of vampire: pure blooded vampires and turned vampires. A turned vampire is just your average vampire, being an undead human. Pure bloods, on the other hand, are born as vampires and are direct descendants from the original vampires. They age up until around their early thirties, at which point their body stops aging and they are immortal. They are generally even stronger than turned vampires and a common quirk for them is they experience either very few emotions or extremely dulled down emotions.

Another uncommon thing I like (that I've only seen once in media) is that if a vampire feeds off of one human repeatedly for an extended period of time, the human will stop aging. But if the vampire were to stop feeding from that human suddenly, then the human will start to age again and more rapidly than normal.

1. Vampire x human priest - A priest is almost finished taking late-night confessionals when a shadowy figure enters the booth next to them and confesses to killing multiple people. What's more, the figure also confesses to being a vampire that revels in the killing and draining the blood of his victims. The vampire would continue to haunt the priest and psychologically torment him with descriptions of the killings, as well as staking claim on the priest's blood as a "heavenly snack" on tap. The priest, on the other hand, is genuinely trying to "save" the vampire, if for no other reason than to stop the torment and the killings. Will the priest be able to get through to the vampire and truly help him? Will the vampire corrupt the priest and tempt him to indulge in sin? ¿Porque no los dos?

2. Cursed vampire x human - A vampire was cursed by a witch centuries ago to forever be bound to his crumbling castle hidden deep in the woods. The vampire finds himself unable to go beyond the property line of his prison, and so has spent ages utterly alone and feeding only off rats he can find scampering about the castle grounds. One fateful night, a human happened to be traversing the woods when a nasty storm caught them off guard, forcing the human to seek shelter in the seemingly abandoned castle. Now that the vampire finally has human prey—and another soul to stave off the boredom and loneliness—he imprisons the human within his castle. Will the vampire try to befriend the human and gain consent (whatever consent can be given in such a situation) to drink from him, or will the vampire simply use and abuse the human? Will the human resist the vampire, give in, or sympathize with his situation? Will the curse be broken. What happens after the curse is removed?

3. Vampire lord x human slave - A vampire lord is presented with a human slave as a gift from another high-ranking vampire. The only issue is that this vampire lord has actively avoided taking any human slaves, as he generally disagrees with the practice and how cruelly human slaves are treated by their vampire masters (alternatively, he could have refused up to this point due to arrogance or because he doesn't see the point in buying something he will immediately drain). But if he were to refuse this gift, then the human would either be resold or drained and tossed aside (what a waste!). So he agrees to keep the human either out of impulse or in order to save them from an even worse fate...plus, this human's blood smells absolutely decadent. Will the vampire be a kind and gentle or cruel and sadistic master? What has the human's past relationships with vampires been like, and how will that influence his interactions with his new master?

4. Injured vampire x human - A human comes across a very badly injured vampire and takes them home to nurse him back to health. How will the human react when he discovers he's taken in a vampire? What will the vampire do when the human finds out?

5. Vampire lord x vampire hunter - A group of vampire hunters arrive at the vampire's castle to finally slay the monster, but they are overpowered by the vampire and all but one of them are slain. The final hunter catches the vampire lord's interest (perhaps he hesitates to shoot?) and so the vampire forces the hunter to submit to him (as his new plaything?). Lots of potential for BDSM dynamic, but can also be played really sweet and fluffy.
