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.

In some fanfiction, Marinette's relationships are explored. Her relationship with Adrien is a popular topic. Writers might create a scenario where Marinette finally confesses her feelings to Adrien in a very unexpected and romantic way, like during a masquerade ball.
