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.
Another interesting plot could be a time - travel aspect. A counselor somehow gets sent back in time to the origin of Jason's story. They then try to prevent the events that led to Jason becoming the unstoppable killer, which would involve interacting with the younger versions of the characters and changing the course of the story.
Well, one interesting story could be about a group of survivors who team up in unexpected ways. They might use their unique skills, like one being a great tracker and another being good at hiding, to outwit the killers in the game's world.
Well, a cool plot could be that there's a portal that opens up and transports the RWBY world into the Friday the 13th universe. The characters then have to figure out how to get back while dealing with the killers and other threats in that world. Weiss could use her glyphs in creative ways to combat the danger.
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.
You could also write a 'Friday the 13th' fan fiction from the perspective of a new camper who is unaware of the legend. This camper could start noticing strange things and gradually piece together the horror that awaits them, adding an element of mystery and suspense to the story.
One idea could be that the Human Friday character is an ordinary person who accidentally stumbles into the Avengers' base. They then start helping out in small ways, like making coffee just right for each Avenger, which becomes a running joke. Eventually, they prove their worth by using their street - smart knowledge to help the Avengers solve a mystery in the city.
One interesting storyline could be a group of survivors who team up in unexpected ways. For example, a normally timid character finds their inner strength and leads the group to safety. They might use the environment in creative ways to avoid Jason, like setting up false trails.
You could do a fanfic for a survival game plot. Imagine the game is set in a post - apocalyptic world. In the fanfic, the main group of survivors find an abandoned military bunker that seems like a haven at first. But it turns out to be filled with traps and secrets. They have to use their wits and the skills they've developed in the game to escape and find a new place to call home.
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.
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 idea could be focusing on a minor character's perspective during the war. For example, a young genin who is caught in the middle of the chaos. They could witness the great battles between the powerful shinobi and have their own journey of survival and growth.
