A plot could involve a time - traveling scenario. The characters from Harry Potter are sent to the world of Until Dawn, or vice versa. They would have to adapt to the new rules and threats. For instance, Hermione would be trying to figure out the logic behind the Until Dawn horror, while the Until Dawn characters would be in awe of the magic they see in the Harry Potter world. This would lead to a lot of character development and interesting interactions.
A great plot for Until Dawn crossover fanfiction might be a crossover with the Final Fantasy series. The Until Dawn characters could be transported into the world of Gaia or some other Final Fantasy world. They would have to adapt to the magic and the different races there. They could go on quests, fight monsters, and maybe even meet some of the iconic Final Fantasy characters like Cloud or Tifa. Another idea is a crossover with the Silent Hill series. The Until Dawn group would find themselves in the fog - filled, nightmarish town of Silent Hill. They would have to face their inner demons as well as the grotesque creatures that lurk in the town. And they could also cross over with a detective - themed show like Sherlock. The Until Dawn characters would be involved in solving mysteries in Victorian London, with Sherlock and Watson helping them out.
You could write a fanfiction about the Wendigo's origin in the Until Dawn universe. It might be interesting to create a story that shows how the first Wendigo was created and how their existence came to be known in that area. Or, a time - travel fanfiction where a character goes back in time to prevent the initial events that led to the chaos in the game. This would involve changing key decisions and seeing how it affects the overall story.
One interesting plot idea could be a crossover where characters from Harry Potter and Breaking Dawn universes meet. For example, Harry and his friends could encounter the vampires and werewolves from Breaking Dawn. They might have to work together to solve a common threat that endangers both their worlds.
One idea could be that Naruto and his friends are transported to the world of Until Dawn. Naruto's ninja skills would be put to the test against the horror elements of Until Dawn. Maybe he has to use his shadow clones to outwit the monsters in the dark. Another plot could involve the Until Dawn characters learning ninjutsu from Naruto.
One idea could be creating an OC who is a long - lost relative of one of the main characters. For example, a cousin of Sam who shows up at the lodge with a mysterious past. Maybe they have some hidden knowledge about the events that are about to unfold at the mountain. Another idea is an OC who is a survival expert hired by the parents of the group to secretly keep an eye on them during their stay. This OC could have unique skills and equipment that add an interesting dynamic to the story. Also, an OC who is a spirit medium could be cool. They start sensing the dark presence in the mountains before anyone else and try to warn the others, but no one believes them at first.
You could create a fanfiction where Mike has to face his fears alone in the woods. This would be different from the game as in the game he is mostly with other characters. It could be a more in - depth look at his character growth when isolated.
Harry Potter himself would be really interesting. He's used to facing dark wizards and magical threats, but the survival horror aspects of Until Dawn would be a whole new challenge for him. His courage and determination would be put to the test in a different way, like having to make quick decisions in a life - or - death situation without relying solely on his magic.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
A traveler could be from a different magical realm entirely and come to the Harry Potter universe. They bring with them unique magical abilities that both fascinate and frighten the wizards in the Harry Potter world. This could lead to a series of adventures where they either share their knowledge or are hunted down by those who fear the new magic they possess.
