One idea could be that a girl finds an old, dusty copy of Jumanji in her attic. When she starts to play, she's transported into the Jumanji world as a character she didn't expect, like a brave jungle explorer. She has to team up with the other players, who are also from her town but in different forms in the game. Along the way, she discovers hidden powers within herself and uses them to overcome the various challenges like wild animals and tricky puzzles.
Another plot could involve the OC being from a different time or dimension within Jumanji. Alex has to figure out how to get the OC back to their own place while also dealing with the normal chaos of the game. Along the way, they develop a deep friendship that changes both of them and how they view the game world.
A crossover with 'The Lord of the Rings' could also be exciting. The Jumanji characters find themselves in Middle - earth. They could team up with the Fellowship to defeat both the Jumanji villains and the forces of Sauron. Picture the Jumanji rhino charging at orcs in the Battle of Helm's Deep.
One idea could be to create a prequel fanfic. Show how the game was created or how it got lost in the jungle in the first place.
