Marinette's character can be developed through her angry outbursts. For instance, when she gets angry, we might see her make rash decisions that she later regrets. This shows her impulsiveness when overcome by anger. Also, her anger could lead to her learning new ways to control her emotions, which is a part of her growth. Maybe she starts to practice meditation or some other calming techniques, which changes her character over time.
One common theme could be Marinette's struggle with her anger in relation to her love for Adrien. Maybe she gets angry when she sees him with other girls out of jealousy. Another theme might be her anger towards Hawk Moth and his villains, as she tries to protect Paris in her Ladybug form. Also, it could explore how her anger affects her friendships, like with Alya, when she's too frustrated to confide in her.
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.
One great fanfiction could be where Marinette discovers the Peacock Miraculous in a hidden attic in Paris. She has to quickly learn to use its powers to stop an akumatized villain that is causing chaos in the city. The story could explore how she combines the powers of the Ladybug Miraculous she already has with the new Peacock powers.
I really like the fanfiction where Marinette uses the Peacock Miraculous to create a sentimonster that can disguise as Hawk Moth. This allows her to infiltrate his lair and find out his true identity. It's a very exciting plot that keeps you on the edge of your seat.
One possible scenario could be that Marinette gets injured during a fight as Ladybug and is rushed to the hospital. In the fanfiction, her friends might come to visit her, and there could be some sweet moments between her and Adrien as he's worried about her. Maybe she has to keep her identity a secret even while in the hospital, which adds an extra layer of tension.
There's also 'The Luka - Marinette Connection'. In this fanfiction, the connection between Luka and Marinette is explored on a deeper level. It starts with Luka noticing Marinette's little quirks and how she tries to hide her feelings. As the story progresses, they start to open up to each other more. The author creates a really engaging story by adding in some mystery elements related to the Miraculous and how it might affect their relationship.
I really like 'Adrien's Discovery'. In this fanfiction, Adrien starts to notice Marinette in a new light. He begins to see all the little things she does for him and how selfless she is. It has some really heart - warming moments, like when Adrien defends Marinette from Chloe's mean remarks. It's a great read if you want to see more of Adrien realizing his feelings for Marinette.
One great fanfiction could be about Marinette getting the Peacock Miraculous in a unique situation. For example, in a world where all the Miraculouses are scrambled among the characters, Marinette discovers the Peacock Miraculous while on a solo adventure. She has to figure out how to use its powers, which are different from the Ladybug Miraculous she's used to. This could lead to some really interesting character development as she tries to master a new set of abilities.
One possible fanfiction could be about Marinette transforming into a mouse - themed Miraculous holder. Maybe she discovers a new mouse - themed Miraculous in a hidden part of Paris. This could lead to her having new powers like super - speed and the ability to fit into small spaces. She could use these powers to outwit Hawk Moth's akumas in a really unique way, and her relationship with Adrien might also take an interesting turn as she tries to keep her new identity a secret from him.
