Who would you like to see as the main character in a Glee reunion fanfiction?

Harry himself could be the main character. After all, he is the Boy Who Lived. In the reunion fanfiction, he could be the center of attention, with everyone looking up to him still. He might be dealing with the pressure of his fame even after all these years, and his journey during the reunion could be about coming to terms with his past and finding new meaning in his life post - Hogwarts.

It could be Harry Styles. Since he has had a very successful solo career, he might be the one who initiates the reunion, using his influence and popularity to bring the boys back together.

Barry Allen from The Flash and Rachel Berry from Glee could be main characters. Barry's speed could be used in interesting ways, like helping Rachel get to auditions on time or saving her from some danger in the city. They could form an unlikely friendship and be at the center of the story.

I think Santana from Glee and Alex from Supergirl would be great to focus on. Santana is sassy and confident, and Alex is strong and brave. They could get into some really fun arguments or team up to take on a common enemy. Also, Quinn from Glee and Lena Luthor from Supergirl could be an interesting pair. Quinn's transformation throughout Glee and Lena's complex character in Supergirl would create a lot of drama and potential for great storylines when they interact.

It could be Rachel. She's very ambitious and often steps on toes to get what she wants. So a story where she does something that she's afraid others will hold against her, like stealing a solo opportunity from someone else, would be interesting.

Jude could be the main focus. He was always the wild card in the group, so it would be interesting to see how he's changed and what new ideas he brings to the reunion.

If Barry Allen joined the Glee reunion in fanfiction, he might bring a new perspective to the group. His experience of saving the world and facing challenges could inspire the Glee characters to be more confident and take risks in their performances. Also, he could use his superpowers to create some amazing visual effects during their shows, like running around the stage so fast that he creates a cool blur effect.

Captain America would be very important. He has always been the moral compass of the Avengers. His leadership skills and ability to bring the team together would be crucial in a reunion. He can bridge the gaps between different members, whether it's Iron Man's tech - based thinking or Thor's more otherworldly approach.

Another option could be Puck. They had a bit of a history in the show. In the fanfiction, they could have reconnected in a moment of passion and now she's pregnant. This would surely stir up a lot of emotions among the other Glee club members, especially those who were close to both of them.

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.
