What could be an interesting plot for a 'Monster High meets FNAF' fanfiction?

One interesting plot could be a school exchange program between Monster High and Ever After High. The students from both schools have to learn to live and study together. Draculaura from Monster High could make friends with Apple White from Ever After High. They could share their different cultures, like how Monster High has a more spooky and unique style while Ever After High is more about fairy - tale traditions. There would be challenges, such as the vampires having to deal with the bright sunlight in Ever After High's world, and the Ever After High students getting used to the monsters' appearances.

Well, perhaps the titans could be like the animatronics in FNAF. The Survey Corps could be trapped in a titan - infested area that has some strange FNAF - like mechanics. For example, the titans are only active at night and there are 'rules' to avoid them similar to the rules in FNAF games.

One possible plot could be that Ben 10's aliens end up in the Monster High world. For example, Four Arms could get into a friendly strength - testing competition with some of the stronger monsters at Monster High like the werewolves. It would be a clash of different kinds of powers and cultures. Ben, in his human form, might also have to figure out how to fit in and make friends with the unique students at Monster High.

In the fanfiction, perhaps Naruto meets the monster girl during his travels. She could have unique abilities that Naruto has never seen before. Their meeting could lead to a series of adventures where Naruto learns about her culture and way of life. This could also be a chance for Naruto to grow as a person, learning to accept differences and finding new ways to use his own skills in cooperation with the monster girl.

Well, perhaps there's a science experiment gone wrong at Monster High that creates a rift in the multiverse, pulling Peter Parker into their world. He teams up with Frankie Stein, who is also interested in science. Together, they try to find a way to close the rift while also dealing with the social drama at Monster High. The vampires might be causing trouble because they don't trust an outsider like Peter, but in the end, he wins them over with his heroic deeds.

A cool plot might be that Voldemort somehow discovers the existence of Monster High and plans to use the unique powers of the monsters there for his own evil purposes. So, Dumbledore sends a group of Hogwarts students, including Harry, to Monster High to warn them and form an alliance. The Monster High students, led by Frankie Stein and Draculaura, join forces with the Hogwarts students. They then have to use a combination of magic and monster abilities to stop Voldemort's plan, which could involve some sort of dark spell that would not only affect the wizarding world but also Monster High if successful.

One possible plot could be that the Teenage Mutant Ninja Turtles somehow end up in the Freddy Fazbear's Pizza place. Maybe they are investigating some strange disappearances that are rumored to be related to the animatronics. They could use their ninja skills to navigate the dark hallways and face off against the haunted animatronics. The turtles' unique personalities would add a fun dynamic, like Mikey being scared at first but then finding the whole situation exciting, while Raph is ready to fight from the start.

Perhaps the plot involves Jackson being the new student at Monster High and his unique charm, which is a blend of his human and monster qualities, draws in a group of female monsters. They then form a sort of harem around him, and the story could be about how he copes with the sudden attention and the different personalities within the group. Some of the girls might be from rival groups in the school, which adds more conflict to the story.

In this fanfiction, Naruto might go to Monster High to seek some kind of special power or knowledge. He could make friends with the monster students, like Frankie Stein. Together they could face challenges like a bad guy who wants to disrupt the harmony between ninjas and monsters. Naruto would use his Rasengan while Frankie uses her electricity powers to fight the enemy.

A simple plot could be that Clawd is exploring an old, abandoned part of Monster High and accidentally falls into a hidden pit. He hurts his leg badly. The other students hear his howls of pain and come to his rescue. They then have to figure out how to get him out and get him medical help in time. This could lead to a series of events where different characters show their skills and loyalty.
