Well, if Marinette was a witch, her relationship with Adrien might be more complex. She could be hesitant to get close to him because of the secrets her witch heritage holds. And Adrien, if he had some sort of angelic nature, might initially be a bit aloof towards Marinette as he tries to keep his true self hidden. Their relationship as Ladybug and Chat Noir would also be different. They might have a deeper, more spiritual connection through their Miraculous.
The relationship between Hawkmoth and his akumas could be more sinister in a Supernatural AU. If the akumas were actual dark spirits, Hawkmoth would be more like a necromancer, controlling these malevolent entities. His relationship with his family, if it was explored in this AU, would be full of secrets and lies. His quest for the Miraculous could be tied to some ancient, supernatural prophecy that he believes will give him ultimate power, and this would put him at odds with the heroes in a whole new way.
One idea could be that the Miraculous are actually ancient supernatural artifacts with their own spirits. For example, the Ladybug Miraculous could be linked to a nature spirit that gives the holder powers related to life and growth. The Cat Miraculous might be tied to a shadow spirit, allowing for stealth and chaos - related powers. This would add a whole new layer of mystery and magic to the Miraculous Ladybug universe.
First, you need to establish the characters' roles. Marinette could be Juliet, with her kind - hearted and sometimes shy nature. Adrien as Romeo, the charming yet somewhat restricted by his family (in this case, perhaps Gabriel's high expectations). Then, think about the setting. Paris could be the Verona - like city, with all its beauty and secrets. For the plot, start with a chance encounter, like in the original show and Romeo and Juliet, that sparks their instant connection. Then, introduce the conflicts, like the feud between their 'families' which could be different groups in the Miraculous Ladybug universe.
The social structure in the Miraculous Ladybug world would also be altered. Humans with Kwami might form groups or factions. There could be those who believe Kwami should be used for the greater good only, and others who think they can use their powers freely. This would lead to conflicts and alliances, much like in real - world politics.
Marinette might become more confident if she's reborn. In the original, she's often shy and clumsy, but in a reborn scenario, she could use her past experiences to be more assertive. For example, she might not stutter as much around Adrien. Adrien, on the other hand, could become more carefree if reborn. He's usually burdened by his family life, but a new start could make him more open to having fun. Chat Noir might also show a different side, perhaps being more strategic instead of just going in head - first all the time.
If the kwami swap involves a kwami with a mischievous nature, Lady Noir's personality could become more playful. She might start cracking more jokes during battles, much like Chat Noir usually does. This would change her overall demeanor and how she interacts with both the villains and Chat Noir. It could also make their partnership more light - hearted or, if Chat Noir isn't used to it, a bit more chaotic as they adjust to this new side of Lady Noir.
Maybe there's a breakdance competition in Paris and both Ladybug and Chat Noir enter it secretly. Along the way, they face challenges not only from their opponents in the competition but also from a supervillain who wants to disrupt the event. Their breakdancing skills become crucial in saving the day and winning the competition as well as protecting Paris.
Spiderman would likely be initially cautious when meeting Ladybug. He's used to operating on his own in New York, and suddenly meeting a hero from Paris with a very different power set would be a bit of a shock. He might be impressed by her ability to create objects with her yo - yo and use them in combat.
Obviously Ladybug and Chat Noir would be the main characters. They could be joined by Alya, who might be a breakdance enthusiast and helps them understand the breakdancing world better. Maybe she could be their breakdance coach in a way.
A haircut can have a big impact. For example, if Marinette cuts her hair short, it might make Adrien see her in a more mature light. He could start to view her as more than just a friend, which would change the dynamic of their relationship. It could also make her more confident around him, leading to more open communication.
In the summer camp setting, characters' relationships can develop in many ways. For Ladybug and Chat Noir, they might become closer as they train together at the camp. They could share more personal stories and secrets, deepening their bond. Other characters like Marinette's friends could also form new friendships with other campers. Maybe Alya meets someone who is also into journalism and they start collaborating on a project about the camp. And then there's the possibility of a love triangle developing between some of the characters, which can add drama to the story.
