In this fanfiction, after Stiles gets bitten by a vampire, he might find himself in the middle of a vampire war. The vampire who bit him could belong to one faction, and now the other faction sees Stiles as a threat or a tool. He has to learn about vampire politics and hierarchies quickly. His friends, especially those who know about the supernatural, would try to protect him. Stiles would also have to deal with the physical and emotional changes that come with being a vampire, like the isolation that can come from living a nocturnal life and the fear of hurting those he loves.
His relationship with his friends would likely become more strained. They might be afraid of him or he might be afraid of hurting them. For example, his best friend Scott, who is also involved in the supernatural world, might be worried about Stiles losing his humanity.
In the 'Harry Potter gets bitten by a vampire' fanfiction, there are numerous possibilities. Harry's appearance might change, with paler skin and perhaps sharper features. His magical abilities could be affected in strange ways. For example, his Patronus might change form due to his new vampiric nature. He could also form new alliances with creatures that are more accepting of vampires, like some werewolves who might see him as a kindred spirit in a way. This could create a rift between him and some of his old friends who are more traditional in their views of the wizarding world, but it could also open up new opportunities for him to explore different aspects of magic and the supernatural that were previously hidden from him.
The fanfiction could be about the adventures Stiles and the puppy have. They could go on hikes together in the forest near his town. During these hikes, they might encounter strange things or other supernatural beings. The puppy could either be scared or curiously investigate. Stiles would have to protect the puppy and also figure out how to deal with whatever they come across.
Perhaps in this fanfiction, Stiles has disobeyed Peter's orders which were crucial for their safety or the safety of others. Peter, being frustrated and feeling responsible, resorts to spanking as a way to show his extreme displeasure. But this kind of plot would also need to deal with the aftermath, like Stiles' reaction of anger, hurt or maybe even understanding, and how it affects their relationship moving forward.
If Stiles were bitten instead of Scott, it would change the entire plot of the story. Stiles is a very different character from Scott. He's more impulsive in his thinking at times. So, when he gets bitten, he might not immediately accept the situation. He could go through a phase of denial, which could put him in danger. His friends would have to work extra hard to convince him to embrace his new identity. And his relationship with Derek might be really interesting, as Derek would have to deal with a much more talkative and inquisitive new werewolf.
Well, it could be that Stiles' secret vampire fanfiction is actually a premonition. He starts writing about a particular vampire who then shows up in real life. But this vampire is different from the typical ones in the stories. Instead of being evil, it's trying to find a way to co - exist with humans. Stiles then has to use his knowledge from the fanfiction to help this vampire, all while still keeping his vampire - loving side a secret from his friends.
It could be his love interest, like I mentioned before, Lydia. She might reject him because she's too focused on her own goals or perhaps she doesn't see Stiles in that way at the time. Their relationship has always been a bit complex in the show, so this would be a likely scenario in fanfiction.
Perhaps the plot twist is that Naruto has to hide his new vampire nature from his friends in Konoha. This would create a lot of internal conflict for him. He might be afraid that they'll reject him if they find out. And at the same time, he has to deal with the new cravings and instincts that come with being a vampire. It could lead to some really tense and emotional moments when his friends start to suspect something is wrong.
Well, often in these fanfictions, Stiles becomes more confident. His physical appearance might also change, like he could start dressing better or have a new haircut that gives him a 'hot' look. For example, he might start wearing more stylish clothes that show off his personality.
The consequences could be far - reaching. Naruto's relationships would surely be strained. His relationship with Sakura, for instance, might become complicated as she may be afraid of him or try to find a way to cure him. His bond with Sasuke could also be tested. Sasuke, being more attuned to darker powers, might have a different reaction compared to others. Moreover, Naruto would have to deal with the vampire community if there is one in the fanfiction world. He would need to learn their rules and how to control his new urges, or else he could become a danger to those he loves.
