Mr. Schuester from Glee could be a main character too. He could be the one who tries to bring the two groups together, seeing the potential in the Glee club and Supergirl working as a team. His role as a mentor in Glee could be extended to Supergirl as she tries to navigate the more complex aspects of human relationships and teamwork in this crossover fanfiction.
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 possible plot could be that the Supergirl characters find themselves in the world of Glee. Maybe Kara has to blend in at McKinley High while also dealing with her superpowers. She could join the glee club and use her super - hearing to help them perfect their harmonies. And she might have to face off against some villains who are after her while trying not to expose her true identity to her new friends in the glee club.
It's possible. Supergirl characters, like any fictional characters in a shared universe, could potentially be fans within their world. However, since there's no official crossover indicating this, it's all speculation. Maybe Kara (Supergirl) would be interested in Glee fanfiction as she seems to be interested in Earth's pop culture.
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.
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.
She might be interested because it offers a different perspective on human creativity. Glee is all about music, performance, and the power of the underdog, and fanfiction adds another layer of creativity to it. Supergirl, being an alien trying to understand humans, could find it fascinating to see how people imagine crossovers between her world and the world of Glee.
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.
Meridith from Grey's Anatomy and Rachel from Glee could be main characters. Meridith is a strong - willed doctor, and Rachel is a determined singer. Their personalities could clash and then grow to understand each other throughout the story.
In 'glee', characters like Rachel Berry would likely be a main character. She's very outspoken and talented, so she could have some great interactions with the Irwins. And from the Irwin side, Bindi or Terri Irwin could be main characters as they are well - known in the Irwin family.
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.
