A really cool plot in South Park time travel fanfiction could be the characters traveling through time to different eras of television. So they end up in the black - and - white TV era of South Park and have to figure out how to get back. They might interact with the early, more primitive versions of the characters they know. This would be full of humorous moments as they try to adapt to the old - fashioned ways of that time period, all while trying to find a way home.
One interesting plot idea could be the boys traveling back to the Wild West days in South Park. They could meet their ancestors and get into all sorts of comical situations, like trying to introduce modern concepts and getting laughed at. Another idea is traveling to the future and seeing a dystopian South Park where all the rules have gone crazy. Maybe they have to fix something in the future to save their present-day South Park.
One idea could be exploring the backstories of the side characters more in - depth. For example, what made Ned Flanders become the way he is in the game's universe. Another could be a time - travel fanfic where the kids go back to a different era in South Park's history and have to deal with the problems there. Maybe they go back to when the town was first founded and encounter the original settlers.
Well, a plot might involve Cartman and Wendy accidentally swapping personalities. This would lead to all kinds of chaos and hilarity in South Park. For example, Cartman - in Wendy's body - would have to deal with girl - related issues, and Wendy - in Cartman's body - would have to handle Cartman's friends. Or perhaps they find a mysterious object that gives them shared dreams, and they have to figure out what the dreams mean and how to stop a bad event from happening in those dreams.
Another plot could revolve around a villain from the game getting a redemption arc. For example, Professor Chaos could decide that being evil isn't all it's cracked up to be. He could try to join the Coon and Friends but face a lot of resistance from the other members who don't trust him. This would create a lot of drama and comical situations as he tries to prove himself.
One idea could be that the kids of South Park form their own survival squad. Cartman might try to hoard all the food, leading to comical in - squad conflicts. Another could be that the zombies are actually the result of a failed experiment by Professor Chaos, and the boys have to find a way to reverse it. Maybe Stan and Kyle have different ideas on how to deal with the zombie threat, with Stan being more practical and Kyle more idealistic.
An OC who is a relative of one of the existing characters could also make for great fanfiction. For instance, a long - lost cousin of Kyle. This OC could bring in new family dynamics and influence Kyle's behavior. They might have different beliefs or values compared to Kyle and his family, which could lead to interesting storylines and conflicts within the family and among the group of friends.
One idea could be a South Park and Adventure Time crossover. Picture Cartman trying to steal Finn's sword or Randy Marsh getting into a crazy adventure with Jake. Another could be a crossover with Rick and Morty. Maybe Mr. Garrison teams up with Rick Sanchez in some wacky interdimensional scheme. And a South Park and My Little Pony crossover would be hilarious too, with the boys having to deal with the colorful world of Equestria.
One plot idea could be that Kenny and Cartman get involved in a time - traveling adventure. Maybe they accidentally go back in time and have to work together to get back to their own time, all while dealing with their usual differences and the challenges of the past era. Another idea is a body - swap situation where they have to experience life in each other's shoes, leading to a lot of comical and also some heart - warming moments as they understand each other better.
One idea could be an OC who has the power to manipulate time and uses it to prevent a major disaster in South Park. Another could be an OC with a unique superpower that makes them an outcast among the kids at first, but then they prove their worth in a big battle. Or an OC who is a new student from a different country and has to deal with the crazy antics of South Park while also bringing in their own cultural elements.
One idea could be them going on an adventure in South Park together, like exploring the mysterious cave that no one else dares to enter. Another could be a story where they have to work together to save the town from some kind of strange new threat. Maybe a super - powered villain shows up and New Kid and Kenny combine their unique skills to defeat it.
Another plot could involve Obi - Wan traveling to the future. He might see a world where the Jedi have been completely wiped out and he has to find a way to bring them back. He could discover new Force abilities or meet descendants of the Jedi who have been hiding their powers all this time. This would be a great way to explore a different kind of Star Wars universe.
