When Ladybug and Cat Noir meet past Ladybugs in fanfiction, it opens up a world of possibilities. The past Ladybugs may have different views on how to use the Miraculous, which could lead to some debates. There could be a sense of competition between the current Ladybug and the past ones. Cat Noir might find himself in the middle, trying to keep the peace. Also, the past Ladybugs could bring with them different relationships they had with their own Cat Noirs in their times, which could create some complex emotional situations. And who knows, they might even team up in a new and unexpected way to face a common enemy.
If Ladybug and Cat Noir meet past Ladybugs in fanfiction, the story would likely start with a lot of shock and awe. The past Ladybugs could introduce new concepts about the Miraculous that the current heroes don't know. This could lead to a training arc for Ladybug and Cat Noir. On the other hand, there could be a villain who is after the knowledge or power that the past Ladybugs possess. So, the story could also turn into a race against this villain to protect the secrets of the past Ladybugs. There could also be some personal growth for Ladybug and Cat Noir as they learn from the experiences of their predecessors.
If Cat Noir steals Ladybug's Miraculous in a fanfiction, it could lead to a dark turn in the story. Maybe he's being controlled by an outside force. This would shatter the trust between them and change the whole dynamic of their fight against evil. The city would be in more danger as Ladybug is a key protector.
One possible plot could be that Naruto is somehow transported to the world of Ladybug and Cat Noir. He might initially be confused but quickly adapt his ninja skills to the new environment. He could team up with Ladybug and Cat Noir to fight against a common enemy, perhaps an akuma that has powers similar to some of the foes in the Naruto universe. Naruto's chakra and jutsu would add a new dimension to their battles.
In the fanfiction, the plot could start with Cat Noir proposing to Ladybug in a really romantic and unexpected way. Then they would start planning the wedding. Ladybug might be a bit hesitant at first because she's worried about how it will affect their superhero duties. But as they work through it, they find ways to balance their personal and superhero lives. And at the end, they have a magical wedding ceremony filled with love and hope for the future.
Mainly, it's Cat Noir and Ladybug. Cat Noir, with his charm and acrobatic skills, is the one who gets hold of Ladybug's Miraculous. This action sets the story in motion. Ladybug, with her intelligence and leadership, will be at the center of the story too. She might be in a state of shock or determination to retrieve her Miraculous. Additionally, characters like Tikki and Plagg, the Kwamis of Ladybug and Cat Noir respectively, could also be important in the fanfiction as they are closely related to the Miraculous and can influence the actions and decisions of the two main characters.
One possible plotline could be Cat Noir finally confessing his true feelings to Ladybug while having her Miraculous. He might struggle with the newfound power and the responsibility that comes with it. Another could be them teaming up in a more equal way than in the original, sharing their secrets and working together to face a greater threat.
Obviously, their best friends like Alya and Nino would be there. Alya could be Ladybug's maid of honor, and Nino could be Cat Noir's best man. Also, all the other superheroes they've worked with in Paris would be invited. And of course, their families, if their identities were revealed by then. Maybe even some of the citizens of Paris who have been saved by them over the years would show up to celebrate this special occasion.
One possible plot could be that Hawkmoth manages to finally corrupt Cat Noir. He might start causing chaos in Paris, attacking Ladybug instead of helping her. Ladybug would then be in a difficult situation, having to either try to save her partner or defeat him to protect the city.
One consequence could be a power imbalance in Paris. Since Ladybug's Miraculous is crucial for maintaining the balance against evil. If Cat Noir takes it, he might not be able to use it as effectively as Ladybug, leading to potential chaos as Hawkmoth could take advantage.
Well, a common fanfiction idea is to give the characters new powers or challenges. Maybe Ladybug has to deal with a new type of akuma that nullifies her usual powers. Or Cat Noir has to face an enemy alone without Ladybug's help. Also, there are fanfictions that play with the idea of the characters' identities being revealed in unexpected ways, which then leads to a whole new set of problems and solutions for them.
