It's possible that in some more niche or edgy corners of fanfic writing, there could be something like this. However, it's not a common or widely promoted type of story. Fanfic writers usually focus on more positive relationships or at least ones that are more in the spirit of the original work.
If such a fanfic exists, possible themes could include the struggle between good and evil, as Xander is likely a 'good' character and the demon is 'evil'.
A 'xander crossover fanfic' typically refers to a piece of fanfiction centered around a character named Xander. Fanfic authors create these crossovers to explore new and interesting scenarios. In this case, it could be that Xander, who may have his own established backstory and characteristics in his original source, is made to interact with different characters, settings, and storylines from other fictional works. This can lead to really creative and unique stories, such as Xander forming an alliance with characters he would never meet in his original story, or having to face new challenges that test his limits in ways that the original story didn't.
Yes, there might be fanfics about their relationship. Fanfics often explore different relationships between characters from various fictional universes. However, it's important to note that not all fanfics are official or follow the exact canon of the original story.
I'm not sure if there is such a fanfic. Fanfics can cover a wide range of topics, but this kind of plot might be a bit unethical and not in line with the positive image of BTS. Usually, fanfics are more likely to focus on positive relationships among the members or fictional romantic relationships within a more acceptable range.
In a fanfic, it could be that after Voldemort's defeat, Harry discovers some old letters or memories that reveal Snape was more to him than just a teacher. Snape might have been secretly watching over Harry since he was a baby. Harry could then approach Snape, and they start to build a relationship. Snape would be hesitant at first, but as time goes on, they become closer, like a father and son. They could go on adventures together in the wizarding world, exploring old magical places that Snape knew from his past.
Well, it could be really interesting. Maybe the demon uncle has some unique powers that he could pass on to Naruto, or perhaps he's a bit of a misfit in the demon world and Naruto has to help him fit in while also dealing with his own ninja life. The uncle could also be a source of some really cool adventures that Naruto goes on, ones that are different from his normal ninja missions.
I'm not sure specifically as 'fanfic' can vary greatly. It could potentially be a fictional story about Xander and Cordy at prom, perhaps exploring their relationship or some romantic or dramatic events during that time.
Well, it could be about a crossover where the characters Xander Harris and Methos from their respective fictional universes interact. Maybe they team up to face a common enemy or go on an adventure together. Without reading it, it's hard to say for sure.
One possible fanfic could be where Ruby travels back in time and her relationship with Jaune (Lancaster) is put to the test. Maybe she goes back to a time before they met and has to find a way to still form the same bond while also dealing with the knowledge she has from the future.
In non - adult Xander game fanfic, his best friend from the game might be often paired with him. Let's call this character Alex. They could go on adventures together and have each other's backs in tough situations. Another character could be the wise old man in the game, who acts as a mentor to Xander and is often by his side to offer advice and guidance.
