Well, in some Vampire Drinking Period Blood fanfiction, the vampire might be a reluctant drinker at first. For example, he could be from an old - fashioned vampire family that only drinks from the neck. But then he meets a girl whose blood during her period has a certain allure. It could also involve a plot where the vampire has to hide this new 'habit' from his vampire friends who think it's abnormal. And there might be a story where the vampire uses the power from the period blood to fight against other evil vampires.
It might be a way to explore unique and taboo topics. Writers like to push boundaries and this is a rather unusual take on vampire lore. Vampires are often associated with blood - drinking, and period blood adds a new and different aspect to it.
One common trope is the 'forbidden love' aspect. A vampire might fall in love with a human, and their need to drink blood creates a lot of tension in the relationship. Another is the 'vampire society' trope, where the story delves into the politics and hierarchies among vampires. Also, the 'vampire hunter' trope is popular, adding an element of danger and conflict as the hunter tries to stop the vampire from drinking blood.
Writers can make vampire characters more compelling by exploring their moral compasses. Some vampires might have strict rules about whose blood they drink, while others are more reckless. Their relationships with other vampires and humans are crucial too. A vampire who has a complex friendship with a human who is aware of their blood - drinking habit can be very engaging. Additionally, their powers related to drinking blood, like being able to sense the health of a person by their blood scent, can add depth.
Some 'twilight period fanfiction' might take the setting of the twilight time to create a sense of mystery. The characters could be involved in a mystery that is only solvable during this special time of day. It could be something like a hidden message that only appears in the twilight light.
One idea could be a story where the vampires from 'True Blood' and 'The Vampire Diaries' have to team up to fight a common enemy, like a powerful ancient vampire or a new type of supernatural threat. Another could be a love story between a character from 'True Blood' and one from 'The Vampire Diaries', exploring how their different vampire cultures affect their relationship.
Physically, he might gain new powers or abilities as mentioned before. But there could also be negative effects. His body could reject the foreign blood, leading to internal pain and weakness.
I remember a drinking game of Kings Cup. There was this one rule where if you picked a certain card, you had to tell an embarrassing story from your childhood. One guy told a story about how he got his head stuck in a fence while chasing a chicken when he was five. It was so funny and made the whole game more exciting.
One interesting story could be about Jeremy exploring his new vampire powers in a way that the show didn't fully explore. For example, he might use his vampire abilities to protect the town from a new threat that's not related to the typical vampires or werewolves. Maybe he teams up with some unexpected characters to fight this new danger.
One interesting story could be about the characters facing a new supernatural threat that was not in the original series. It could involve them using their unique powers in different ways to combat it.
One interesting Naruto blood fanfiction could be about a hidden bloodline ability that Naruto discovers later in life. For example, it might be related to an ancient Uzumaki clan power that gives him the ability to control time on a small scale. This could lead to really cool fight scenes where he freezes opponents or speeds up his own movements.
