What are some interesting plot ideas for a Glee reunion fanfiction?

One idea could be exploring the backstories of the characters in more depth. Maybe there are hidden pasts that influence their actions in the 'gloaming glee' world.

A great plot could involve a Pokemon reunion where the Pokemon themselves organize the event without the trainers knowing. They set up all kinds of challenges and games for each other, and the trainers are left wondering what their Pokemon are up to. It could also be about a group of retired trainers who reunite and share stories of their adventures, and their Pokemon also have a sort of 'reunion' among themselves, showing off new skills they've learned over the years.

A possible plot could be that Barry Allen is running through time and space and accidentally disrupts the Glee reunion. He then feels responsible and decides to help make it the best reunion ever. He could use his super speed to bring in some of the old Glee members who couldn't make it initially. And in the process, the Glee characters teach him some valuable lessons about the power of music and friendship.

One idea could be that a character gains a special musical power after being struck by lightning during a glee club rehearsal. They can then use this power to create amazing performances and inspire the whole club.

A plot could involve a character from Glee accidentally stumbling into the Starkid universe. For example, Rachel Berry could find herself in the middle of a Starkid rehearsal. She might initially be confused but then realizes she can learn a lot from their unique style of performing. This could lead to a series of comical and heartwarming interactions as she tries to fit in and contribute to their shows.

A really cool idea for a fanfiction could be that Rachel and Finn swap personalities for a day. Finn suddenly becomes super - focused on his Broadway dreams like Rachel, and Rachel has to deal with Finn's more laid - back attitude towards things. It would be a humorous and also a great way to explore their relationship from a different perspective.

One plot could be about Artie and Quinn helping each other through college applications. Since they both have different strengths, they could support one another in achieving their academic dreams.

One plot idea could be that the Shadowhunters need to find a way to defeat a powerful demon that can only be weakened by a special type of music. So they seek out the Glee club. The Glee club members are hesitant at first but then realize the importance of their role. Another idea is that a spell gone wrong in the Shadowhunters' world sends some of their key characters to the Glee club's world. There, they have to adapt to high school life while also trying to find a way back. And the Glee club helps them blend in and in return, they learn about the Shadow World.

One plot idea could be Quinn and Joe collaborating on a musical project for Glee club. They might have different styles at first, but as they work together, they learn from each other and grow closer.

One idea could be a singing competition between the Glee club and the students from Victorious. They could meet at a national music event and initially be rivals, but then start to collaborate and learn from each other's styles. For example, the Glee club could teach the Victorious crew about more traditional musical theater numbers, while the Victorious students could introduce the Glee club to more modern pop and hip - hop influenced performances.
