In a 'Friday the 13th' fanfic with Bree, it could be that Bree is a relative of one of Jason's previous victims. She has a vendetta against Jason and has been training to take him down. She comes to Crystal Lake armed with knowledge and skills. However, Jason is much more powerful and cunning than she expected. The story could then be about her struggle, her growth in the face of such a terrifying adversary, and whether she can ultimately succeed in her mission.
Maybe Bree is a journalist who is investigating the rumors around Crystal Lake. She gets more than she bargained for when she encounters Jason. As she tries to escape, she discovers some secrets about the place that could potentially stop Jason once and for all. Along the way, she meets other survivors and they all work together to fight the horror.
Honestly, I haven't come across a 'Friday the 13th' fanfic specifically centered around Bree. But if it exists, it might explore Bree's backstory, like how she ended up in the path of Jason Voorhees. It could also show her relationships with other characters in the 'Friday the 13th' lore, perhaps she has a love - interest or a rival. The best way to find it is to look through fanfic tags on relevant websites.
One possible plot could be that the RWBY team is on a mission in a forest that has a dark history similar to Crystal Lake. They start to notice strange things happening, like people disappearing. Then, they encounter a masked killer similar to Jason. They have to use their skills as huntsmen and huntresses to fight this new threat while also trying to figure out the mystery behind the killer.
One possible plot could be that the vampires from Twilight somehow end up in the world of Friday the 13th. Maybe they get transported there by a strange magical event. The vampires' powers would be a new and terrifying element in the already spooky Friday the 13th setting. They could either be enemies of Jason or form some sort of uneasy alliance with him.
Maybe a fanfic where the counselors team up in a more strategic way. Instead of just scattering, they set traps and work together to try and defeat Jason. They could use the environment in clever ways, like using the old cabins as barricades or luring Jason into a dangerous area.
In a crossover with another horror franchise, like 'Scream', the killer from 'Scream' could be revealed as the mastermind behind Jason's actions. So instead of Jason just being a mindless killer, he's being manipulated by someone else for their own twisted reasons. This would completely change the dynamic of the fanfic.
One possible plot could be that Jason's sister discovers the truth about her brother's actions and tries to stop him. She might have some hidden powers or knowledge that could be used to put an end to the killings.
One idea could be a crossover with 'Nightmare on Elm Street'. Jason Voorhees could find himself in Freddy Krueger's dream world. Maybe the two iconic killers start to compete for victims, which would create a really tense and spooky situation.
The unique part is the original characters. They can bring new perspectives to the 'Friday the 13th' world. For example, an OC could be a survivor with a special skill or backstory that we haven't seen in the original movies.
In the 'Friday the 13th' story, Jason Voorhees is the central figure of horror. The story is set at Camp Crystal Lake which has a dark past. Jason was drowned as a boy and his mother started a killing spree in revenge. After his mother's death, Jason continued the tradition. He lurks in the woods and around the lake, attacking anyone who dares to be in his territory. The movies are known for their spooky atmosphere, sudden scares, and the iconic image of Jason with his hockey mask.
One possible plotline could be that the characters in 'Girl Meets World' experience a series of strange and spooky events on Friday the 13th. Maybe they visit an old, haunted house as part of a school project. The superstitions surrounding Friday the 13th could add an element of mystery and fear to their exploration.
