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.
The relationship between Ladybug and Chat Noir might become more strained as they might have different ideas on how to prevent something like the Collector incident from happening again. On the other hand, Marinette and Alya's friendship could grow stronger as Alya supports Marinette through the aftermath. And Adrien might become more distant from his father as he realizes the importance of his role as Chat Noir and the potential danger his father's actions (if related to the Collector in some way) could pose.
In the werewolf form, Chat Noir might become more aggressive. His usually flirty and carefree nature could turn into a more territorial and protective one. He would be more likely to attack threats without hesitation. For Ladybug, she could become more instinct - driven. Her normally calm and collected self might struggle to keep her emotions in check, as the werewolf form brings out more primal instincts. And for characters like Alya, she might be more curious and fearless in werewolf form, always eager to explore and learn about this new side of herself.
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.
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.
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.

It could also be Lila. In this au, she could be a master manipulator who uses her lies to create chaos among the heroes and the citizens. She teams up with other criminals and uses her charm to get away with various crimes while making Ladybug and Chat Noir look bad. She might even be able to get her hands on some sort of powerful weapon or item that gives her an edge over the heroes.
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.
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.
