What are some interesting ideas for glee future fanfiction?

One idea could be that the characters from Glee find themselves in Central City during one of The Flash's battles. Maybe they get caught in the crossfire and The Flash has to save them while also dealing with the meta - human threat. For example, Rachel could be singing on the street when a meta - human causes chaos nearby.

Perhaps a story where the new generation has to revive the glee club after it has fallen into disarray. They could discover old tapes or stories from the original members which inspire them to bring back the glory days. They may also have to deal with different music trends compared to the first generation.

Another concept is that a villain from The Flash's world uses the power of music (inspired by the Glee club's performances) to create chaos. The Flash teams up with the Glee club to reverse the effects of the music - based villainy. The Glee kids could use their knowledge of harmony and rhythm to counter the negative musical energy, while the Flash uses his speed to stop the physical manifestations of the villain's attacks.

One idea could be that the characters from Glee perform a musical version of Beauty and the Beast within the Glee club setting. They could assign roles like Rachel as Belle and Finn as the Beast. Another could be a crossover where the Beast from the fairy tale somehow ends up in the Glee universe and has to learn about music and friendship from the Glee kids. And a third idea might be that the Glee club does a fundraiser by putting on a modern - day retelling of Beauty and the Beast, with unique twists on the characters and their relationships.

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.

One idea could be that the Glee club is invited to perform at a big event in National City where Supergirl is also present. They could end up teaming up to save the day when an alien threat targets the event. The Glee kids' unique talents could be used in unexpected ways, like using their voices to disrupt an alien's sonic weapon.

One idea could be that the original Glee club members reunite to put on a charity show. They face old rivalries resurfacing but also rediscover their love for performing together. Maybe some of them have become big stars and some are still struggling, and they learn from each other's experiences.

One idea could be Finn getting a bad case of the flu right before a big performance. His friends in Glee club would then have to figure out how to cover for him or help him get better in time. Another could be that Finn has an ongoing illness that he's been hiding from the club, and it finally starts to affect his ability to participate fully. Maybe he faints during a rehearsal, and then everyone rallies around him to support him through his sickness.

One plot idea could be that Rachel and Will collaborate on a very unique musical production. They face challenges like budget cuts and a lack of student interest at first. But through their combined efforts and Rachel's determination and Will's teaching skills, they manage to turn it around and create a show that wows everyone.

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.
