A time - traveler from the future could also be an interesting main villain. This character could have seen a dark future where the Miraculouses were misused and has come back to the present to destroy them all. But in his quest, he doesn't care who gets hurt, and Emma has to stop him from changing the past and future in a bad way.
Maybe Emma starts to have dreams that are actually premonitions of future akuma attacks. She then has to convince Ladybug and Chat Noir that her dreams are real without revealing too much about herself. Or, she could find a way to create her own superhero identity and team up with Ladybug and Chat Noir, but struggles with the responsibility that comes with it as she is still a young girl.
One great fanfiction is 'The Secrets of Gabriel Agreste'. It delves deep into his motives and the backstory that we don't often see in the show. It gives a more complex view of his character.
Well, in many 'Miraculous Ladybug Emma Fanfiction' works, the author explores different aspects of Emma's life. It could be her daily life as a normal girl who suddenly discovers the Miraculous world. Or perhaps she is involved in a love triangle with some of the main characters from the original show. The fanfiction gives a chance to expand on the lore and create new and exciting storylines.
The fanfiction should also fit well within the world of Miraculous Ladybug. It should respect the existing lore and character relationships. If it can add new elements to the story while still feeling like it belongs in the same universe, that's a great sign of a good Gabriel Agreste fanfiction.
Well, a common theme is the mystery surrounding Emilie. Fanfic writers often try to solve this mystery in their own ways. For instance, they might come up with theories about where she is or what really happened to her. Love and family are also big themes. Since Emilie was part of the Agreste family, fanfictions explore the family dynamics, like how Gabriel's actions are related to his love for Emilie and how Adrien copes without his mother's presence.
The unique character of Emma. She can bring a fresh perspective to the Miraculous Ladybug world. Maybe she has a different way of using the Miraculous powers compared to the main characters in the original.
Definitely Emilie. Fanfictions can give her a voice and a more in - depth personality. Gabriel is also quite a character in these stories. His motives and actions related to Emilie are often explored. We get to see different sides of him, like his desperation to bring her back. And then there's Adrien. His relationship with his mother, even in the absence of her physical presence, is a key aspect. His growth and how it's affected by Emilie's situation make him an engaging character in these fanfictions.
A possible main villain could be a character from Ladybug's past who has discovered her identity and is using that knowledge to create chaos. They could be blackmailing her or trying to steal her Miraculous by setting up elaborate mysteries and traps for her to solve.
Hawkmoth is an obvious choice. His whole mission is to obtain the Miraculouses, and in a death fanfiction, he could succeed in a more devious way than in the original series, directly or indirectly causing Ladybug's death.
An evil alien warlord could be the main villain. This warlord could be bent on conquering Earth and other planets in the universe. He might see the Miraculouses as a threat and try to destroy Ladybug and Chat Noir first.
