She could gain new powers. For example, if she got the Fox Miraculous instead of the Ladybug Miraculous, she'd have the power of illusion. This would change the way she battles villains completely. She could create false images to mislead them, rather than using the more direct combat approach of the Ladybug Miraculous.
Maybe she was framed by an Akuma - influenced villain. In the 'Miraculous Ladybug' world, this is quite likely. Her arrest could be part of a larger scheme to distract Ladybug and Chat Noir. So, Ladybug might have to balance her superhero duties with clearing Marinette's name, which would be a really interesting plot twist.
In a fanfiction scenario where Marinette gets akumatized, it's a really fascinating concept. Marinette is known for her strong will and positive attitude, but if she's akumatized, all that could be flipped. Her akumatized form might be influenced by her repressed emotions, such as her jealousy over Lila's lies being believed so easily. Her akuma - powered actions could start to cause chaos in Paris. And it would be a great opportunity for the other characters to step up and try to save her, not just as Ladybug, but as Marinette. There could be a lot of self - discovery and character growth for everyone involved as they face this new and unexpected threat.
In different Miraculous fanfiction, Marinette can be portrayed in various exciting ways. Sometimes she might have new powers or face different challenges compared to the original series. For example, in some fanfics, she could form unique partnerships with other Miraculous holders that we don't see in the show.
She could be in the hospital because of a bad fall during a chase in her Ladybug form. Her classmates might start a fundraising campaign to help with her medical bills. And Chat Noir could be secretly visiting her at night, leaving little gifts by her bedside.
In this fanfiction, Marinette and Tikki could be transported to an alternate version of Paris. Here, everything is different, and they have to find a way back. Marinette uses her wits and Tikki's knowledge to navigate this strange new world. They meet different versions of their friends and enemies, and through their adventures, they learn more about themselves and their relationship.
She could have been kidnapped by a new villain who wants to use her skills as a fashion designer for some evil purpose. Since Marinette is so talented, this villain might think she can create special costumes or items for their evil plans.
Her self - confidence might be affected in a new way. The Ladybug Miraculous gives her a certain level of confidence because of its importance. But a different Miraculous might make her question her abilities at first. For instance, if she got the Bee Miraculous, she'd have to adjust to its stinging power and the role of being a more assertive hero.
Perhaps there's a beach fashion show in the fanfiction. Marinette enters wearing her bikini and wows everyone with her unique style. It could also be a moment where she catches the eye of Adrien, who is there to support his friends in the show.
She might receive a mysterious gift that has some connection to her Ladybug identity. For example, it could be an ancient book about the Miraculous that has been lost for centuries. This gift could lead her on a new adventure to uncover more about the history of the Miraculous and her role as Ladybug.
The theme of Marinette's self - discovery is also quite common. In different fanfictions, she may question her role as Ladybug, her identity outside of being a superhero. There could be stories where she has to make tough choices between her normal life and her superhero duties. And sometimes, in fanfiction, her relationships with other characters like Chloe or Luka are explored in ways that give new perspectives on her character.
