What could be the plot of a 'Harry Move Sunnydale' fanfic?

Yes, there might be. There are many fanfic communities out there where such crossovers could exist. You could start by checking popular fanfic websites like Archive of Our Own or Fanfiction.net.

Well, perhaps Harry could bring his magic skills to Sunnydale and use them to fight the demons there. He might team up with the local Scooby Gang and together they face new and more powerful threats.

Well, perhaps it could be about Harry and Severus starting a new life in Forks. Maybe they have to deal with the different climate and the local community there. They could be exploring the unique features of Forks while also having some magical elements intertwined, like using magic secretly to adapt to the new place.

In this fanfiction, Harry might also meet Willow, a powerful witch in Sunnydale. Their interaction would be fascinating as they both have magical abilities but learned and practiced magic in very different ways. And of course, he could meet Xander, who might initially be skeptical of Harry but later become his friend as they fight side by side against the various threats in Sunnydale.

Well, he might encounter a whole new set of magical and non - magical challenges. Sunnydale is known for its vampires and demons, so Harry would probably have to use his magic in different ways compared to Hogwarts. Maybe he'd team up with the Scooby Gang to fight the forces of evil there.

Well, perhaps they move to Forks for a new start. Maybe they are intrigued by the different atmosphere there compared to their own magical world. They could explore the non - magical side of life, make new friends, and Luna might find some really interesting natural phenomena in Forks to study.

Perhaps they go to Forks to start a new life away from the wizarding world. They could find common ground with the outcast characters in Forks. Harry, with his experience of being an outsider in the wizarding world, and Draco, who has also had his own issues of fitting in, might bond with the misfits in Forks. They could end up helping the local community while also learning about themselves.

One possible plot could be that they move to America to start a new life away from the wizarding war in Britain. They might discover new magical communities in America, like Ilvermorny, and get involved in protecting its secrets. Maybe they meet new friends and enemies along the way and use their combined skills from Hogwarts to face new challenges in this different magical environment.

Well, it could be that Harry and Cedric find themselves in Forks for some magical reason. Maybe they are on a mission to protect the town from dark forces that are starting to surface there. They might use their magical skills in a world that is not used to magic, like in Forks which is more of a normal human town in the Twilight universe.

Obviously, Buffy would be a major character he'd interact with. They could start off as wary of each other but then grow to respect one another's fighting skills. Giles too, as he has a wealth of knowledge about the supernatural, and he and Harry could have some interesting discussions about different types of magic.
