A great plot could be that baby Adrien has a vivid dream where he is already a grown - up Cat Noir. He doesn't fully understand it but when he wakes up, he has some cat - like instincts. He starts chasing imaginary butterflies around the house and climbing on furniture like a little kitten, much to the amusement and confusion of his family.
One idea could be baby Adrien discovers a small Kwami - like creature in the garden. It's not a real Kwami but has some magical abilities. And as he plays with it, strange and cute things start to happen around the house.
One plot idea could be that Kagami and Adrien are paired up for a fencing competition. During their training sessions, they start to realize they have more in common than they thought. Kagami begins to understand Adrien's love for freedom outside of his strict model life, and Adrien admires Kagami's determination. This could lead to a budding friendship that might turn into something more, with the added complication of Ladybug in Adrien's life.
Another idea is that Adrien's mom was an artist who used her art as a form of magic. She created a world within her paintings, and when she disappeared, she was actually trapped in that world. Adrien stumbles upon this world and has to navigate through it, facing the creatures and challenges his mother created, all while trying to find a way to free her and bring her back to the real world.
A plot could be where Adrien and Kagami start a fencing club together at school. They recruit other students and in the process, they grow closer. They face challenges like getting enough funding for equipment and dealing with a rival fencing club from another school. Through these experiences, their relationship deepens.
One great plot idea could be a story where Marinette and Adrien are paired up for a school project that requires them to travel to a different city. This would force them to spend a lot of time together outside of their usual Parisian setting. They could discover new things about each other and grow closer. Another idea is a fanfiction set in a future time where they have both retired as superheroes. They start to reminisce about their past adventures and realize how much they've been through together, which reignites their feelings in a more mature way. And a third idea could be a story where they get trapped in an alternate dimension. There, they have to rely solely on each other to find a way back home, which deepens their bond.
One idea could be a story where the Peacock Miraculous has a unique malfunction that causes it to create unexpected akumas. For example, instead of creating the usual villains, it creates akumas that have the power to spread positive emotions but in a chaotic way that still disrupts Paris. Another idea is a fanfiction where the holder of the Peacock Miraculous has to team up with Ladybug and Chat Noir to fight against an ancient evil that is specifically drawn to the power of the Peacock. This could involve exploring the history of the Miraculous and its connection to this new threat.
A plot could involve Adrien being given the Peacock Miraculous by a mysterious figure. With this new power, he tries to use it to protect a loved one from a new, powerful enemy. However, the power of the Peacock Miraculous starts to affect his emotions and he has to learn to balance his feelings while using the miraculous effectively.
One possible plot could be that Marinette, in an overzealous attempt to get closer to Adrien, creates a 'trap' of sorts. Maybe she arranges for a photoshoot at a location where only she and Adrien are present, under the guise of it being a school project related to fashion. She could have set up the set in a way that Adrien would be impressed by her creativity and they would have an extended period of time to talk and bond.
The plot could involve Adrien being akumatized after a big fight with his father. He might feel extremely alone and angry. His akumatized form could have the ability to freeze time in certain areas. Ladybug would struggle to figure out how to defeat him without hurting him too much. She might have to team up with some of the other Miraculous holders like Rena Rouge and Carapace to come up with a plan.
One idea could be Multimouse having to team up with an unexpected ally, like a villain who has a change of heart for a short time. Another could be Multimouse getting lost in an alternate dimension and having to find her way back while facing new challenges.
One idea could be Ladybug and Chat Noir having a heart - to - heart conversation in bed after a particularly tough battle. They could share their fears and insecurities that they usually hide behind their superhero personas.
