Well, for me, it would be Blaine from Glee and Winn from Supergirl. Blaine is known for his charm and musical talent, and Winn is the tech - savvy guy in Supergirl. They could collaborate on creating some high - tech musical equipment for a big performance. And then there's Mr. Schuester from Glee and J'onn J'onzz from Supergirl. The teacher - like nature of Mr. Schuester and the wise leadership of J'onn J'onzz could lead to some really cool mentoring - type storylines within the fanfiction.
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.
The Flash (Barry Allen) could also be a great character to include. Since he has crossovers with both Arrow and Supergirl in the actual shows. His light - hearted nature and super - speed abilities could add a different dynamic to the story. He could act as a mediator between Oliver and Kara when they have differences. Also, villains like Lex Luthor could be really interesting to explore in this crossover. His brilliant mind and devious plans could pose a significant threat to both heroes and force them to work together in new ways.
Rachel Berry from 'Glee' would be a key character. She is so ambitious and has a strong vision for music. In a crossover, she could clash with Aubrey from the Barden Bellas over leadership and musical direction. This conflict could drive the story forward as they both try to prove their way of doing things is the best.
Kara and Rachel would be an interesting pairing. Kara with her superpowers and Rachel with her powerful voice. They could learn from each other, like Kara teaching Rachel some self - defense moves and Rachel helping Kara with her stage presence.
Edward would be really interesting. His brooding and mysterious nature from Twilight would contrast sharply with the often over - the - top and energetic world of Glee. He could bring a sense of depth and angst to the Glee club. His musical talent, which was hinted at in Twilight, could be explored more fully in the Glee setting. He might struggle with fitting in, not because he's not talented, but because of his vampire secrets.
Captain America's protege would be an interesting choice. He has big shoes to fill, and seeing how he has developed in the absence of Captain America would be engaging. He might struggle with living up to the legacy, but at the same time, he could bring his own unique style and leadership to the group during the reunion. His relationships with the other young Avengers, especially those who knew Captain America well, could be a major part of the story.
Well, maybe the characters from both shows would come together for a big musical event. They could perform some amazing mash - up songs. For example, Supergirl's heroic characters could join the Glee club on stage and sing some inspiring anthems together.
Angela would be a great character to focus on. She was such a strong and independent character. In a reunion, we could see how she has balanced her career and personal life. Maybe she has traveled the world and has amazing stories to share, and how her relationship with Shawn has either deepened or changed in unexpected ways.
I think Santana would be a key character. She has such a strong personality and her development from a bully to a more empathetic person could continue in the future story. Brittany might also be in the spotlight as she's always been a bit of an enigma and her relationship with Santana could be explored further. Additionally, Mr. Schuester could be important as he could be the guiding figure for the new generation of glee clubbers or dealing with his own post - glee club life.
If Supergirl characters watched Glee fanfiction, it would be a very strange encounter. Supergirl herself might see the parallels between the tight - knit group in Glee and her own team. She might admire the way the characters in Glee fanfiction overcome their problems through music, just as she uses her powers to overcome challenges. However, the more serious characters like Guardian might think it's a waste of time and not understand why people write such fictional stories about a high - school club when there are real - world problems to solve.
I think Debbie would be really interesting to focus on. She could be in charge of some important part of the wedding, like the flower arrangements, and things go horribly wrong. It would be fun to see how she deals with the pressure. And Frank, well, he could be the wildcard. He might show up drunk and cause all kinds of trouble, but also have some surprisingly tender moments with the family during the wedding.
