In an akumatized Ladybug fanfiction, the akuma might enhance her powers in unexpected ways. For example, her Lucky Charm could become a more powerful and unpredictable object. Her akumatized form might also have a darker and more menacing look, perhaps with a more aggressive fighting style. Writers could explore how the heroes and villains interact with this changed Ladybug.
Marinette might become more confident if she's reborn. In the original, she's often shy and clumsy, but in a reborn scenario, she could use her past experiences to be more assertive. For example, she might not stutter as much around Adrien. Adrien, on the other hand, could become more carefree if reborn. He's usually burdened by his family life, but a new start could make him more open to having fun. Chat Noir might also show a different side, perhaps being more strategic instead of just going in head - first all the time.
One common plot twist is the revelation of a character's true identity in a different way than in the original show. For example, a side character might turn out to be a Miraculous holder secretly. Another is when the love square between Marinette, Adrien, Ladybug, and Chat Noir gets a new dynamic. Maybe they find out about each other's identities earlier than expected, which completely changes their relationship and how they interact with each other in the story. And sometimes, new villains are introduced that have a connection to the main characters' pasts, which throws a wrench in their plans to protect Paris.
