One idea could be a prequel focusing on how the Bellas formed in the first place. Maybe explore the early relationships between the members like Aubrey and Chloe.
Another plot could be a time - travel fanfiction where the Bellas go back in time to the era of their idols in acapella and learn new techniques. This would add an element of adventure and discovery to the story. They could meet old acapella groups and have to compete in a different style of competition.
A story about the Bellas facing a new, super - talented rival group from another country. This would force them to step out of their comfort zone and incorporate new musical styles into their performances. They could also have a cultural exchange as part of the story, which would be really interesting to explore.
One plot idea could be that the Barden Bellas somehow get caught up in a supernatural hunt. Maybe they're performing at a haunted location and strange things start to happen. The girls then team up with the Winchesters to figure out what's going on and stop the evil entity.
A crossover with 'High School Musical' would also be cool. Picture the Pitch Perfect girls and guys going to the same school as the High School Musical characters. There could be a big musical showdown where the two groups have to combine their talents. The Pitch Perfect crew's edgy acapella style might clash and then blend with the more traditional musical theater style of High School Musical, leading to an amazing performance.
One idea could be a singing competition where the groups from both 'Pitch Perfect' and 'Glee' participate. They could start off as rivals, but then gradually learn from each other's styles. For example, the Barden Bellas could teach the New Directions some of their a cappella arrangements, while the New Directions could introduce more pop and show - tune elements to the Bellas.
One idea could be that the OC is a new student at Barden University and has an amazing, unique vocal talent that catches Donald's attention during auditions for the a cappella groups. Maybe the OC has a secret past related to music that gradually unfolds throughout the story, and Donald helps the OC overcome some insecurities related to it.
One idea could be exploring the backstories of the characters in more detail. For example, what made Fat Amy so confident? Another could be creating a new a cappella group that challenges the Barden Bellas. Maybe they have a unique style or set of members.
One idea could be a fanfic that focuses on the backstory of how the Barden Bellas formed. Maybe explore the different auditions and how the original members first met and bonded over their love for a cappella.
One idea could be a story where a new character who is seen as a 'Sex God' joins the Barden Bellas. Maybe he has an amazing voice and a charm that throws the group dynamic into chaos at first. But eventually, he helps them reach new heights in their performances.
One idea could be a Pitch Perfect fanfiction focused on the behind - the - scenes of the a cappella competitions. For example, how the groups practice secretly to outdo each other. Another could be about the characters' lives before joining their respective groups, like Aubrey's high - school days and how she developed her strict leadership style. And a third idea could be a story where the groups collaborate on a special project to promote a cappella music in schools.
Another plot could involve Rapunzel's hair having the ability to repel Pitch Black's nightmares. Pitch discovers this and tries to cut off her hair. However, Rapunzel uses her wits and the help of Pascal and Maximus to outsmart him. In the process, Rapunzel realizes she has more power within her than she ever knew, not just in her hair but in her spirit, and she becomes a force to be reckoned with against Pitch.
Another plot could revolve around Riddick trying to teach Jack some of his survival skills. He shows her how to track in the dark, use minimal resources for maximum effect. This could lead to a deeper bond between them as they face various challenges together. For example, they get trapped in a cave system and have to rely on each other to get out.
