Well, in some svtfoe evil star fanfiction, there might be the concept of redeeming the evil star. Fans could write about a character trying to find the good within it, perhaps through a powerful spell or a deep emotional connection. It could also be about the evil star's hidden powers that are only revealed under certain circumstances, like during a lunar eclipse or when in the presence of a particular magical artifact.
One interesting concept could be characters from different universes within the fanfiction meeting and interacting. For example, Star from 'Star vs the Forces of Evil' might meet characters from other popular shows. This can lead to unique storylines and character developments. Another concept could be the combination of different magical elements from the show and the crossovers. It can create new powers and challenges for the characters.
In genderbend fanfiction, the character designs can be really fascinating. The male version of Star might have different magical powers or a different style of using magic. He could have a more brash or bold approach compared to the original Star, which would lead to different plot developments when facing the Forces of Evil.
Some fanfics focus on the origin stories of the villains in Star vs the Forces of Evil. They might explore what made Toffee so evil or how Ludo became the way he is.

Some fanfictions might explore Ezra as an evil character through a time - travel plot. For example, he could go back in time, get corrupted by past Sith lords, and then return to his own time as an agent of the dark side. His knowledge of the future and new - found dark powers would make him a formidable and terrifying adversary. Also, an evil Ezra might form his own dark side cult within the Star Wars universe, recruiting those who feel disenfranchised by the Galactic Empire and the Rebel Alliance alike.
In some cases, villains from the original SVTFOE series could be main characters in relation to the evil star fanfiction. For example, Toffee. He might have some sort of connection to the evil star, either trying to use it for his own evil purposes or having some past history with it that is revealed in the fanfiction. There could also be new characters created specifically for the fanfiction that are related to the evil star, like a guardian who was tasked with keeping it in check but failed.
Perhaps the character interactions are a key concept. Imagine Dipper from Gravity Falls meeting Star from SVTFOE. Dipper's inquisitive nature and Star's bold and impulsive personality could lead to some really fun and unexpected adventures. They might team up to solve a mystery that involves both the Gravity Falls' mystery and the magic of SVTFOE.

One interesting concept could be the re - imagining of characters' moral alignments. For example, a normally good character might be swayed to the 'evil side' by the power of the 'evil pieces'. Another concept could be the unique abilities or powers that these 'evil pieces' bestow upon the characters, which could lead to new and unexpected story developments.
