One of the common themes is probably the struggle with self - identity. Glee has a diverse set of characters with different backgrounds and personalities. Fanfiction might focus on how trust and security within the group help the characters to better understand and accept themselves. Also, themes of acceptance in general, both within the group and from the outside world, can be explored through the lens of trust and security.
Rachel Berry is probably one of the most popular. She's very ambitious and her journey in the show makes her a great character for fanfiction exploring trust and security. Finn Hudson could also be popular. His leadership role in the Glee club means he has to deal with issues of trust among the members. And of course, Santana Lopez, with her tough exterior but vulnerable inside, offers a lot of room for exploring trust - related storylines.
Betrayal is a very common theme. Since it's about a breach of trust, it often involves one character feeling betrayed by another, like a friend turning on a friend or a lover cheating.
One common theme is romance. Writers often explore Mason's relationships, whether it's a romantic relationship with another character from Glee or a new character created for the fanfiction.
One common theme is family. In glee holiday fanfiction, often the characters are either reuniting with their families or dealing with family issues during the holidays. For example, Quinn might be trying to figure out her relationship with her parents over Christmas.
One common theme is self - discovery. Ryder often goes through a journey of finding out more about himself, his talents, and his place in the Glee club. Another theme is friendship. He forms deep bonds with other club members.
Musical achievement is also a common theme. Given that Glee is centered around music, fanfictions about Spencer often include his musical growth. This could be about him learning new singing techniques, getting a big solo, or even writing his own music.
Another common theme is self - discovery. Since both Will and Emma have their own personal growth arcs in the show, in fanfiction, they often continue to discover things about themselves while in their relationship. It could be about Emma learning to be more confident or Will realizing his true priorities in life.
A prevalent theme is competition. Since the glee club participates in various competitions, fanfictions often focus on how Madison deals with the pressure of competing, the rivalries with other clubs, and how she helps her own club succeed. Also, the theme of love and romance sometimes pops up, like Madison's possible romantic interests within or outside the club.
Love is a very common theme. Most of the fanfictions revolve around the romantic relationship between the two characters. It could be a slow - burn love story or an instant connection kind of thing.
One common theme is the exploration of complex relationships among the characters. In mature Glee fanfiction, it could be more in - depth relationships that involve love, heartbreak, and personal growth. For example, the relationship between Finn and Rachel might be explored in a more adult and complex way.
