How can the characters of Miraculous Ladybug fit into the Beauty and the Beast story?

Let's say that the Kwamis have some sort of connection to the magic in the ocean. Tikki could have the power to grant Ariel temporary powers on land similar to how she gives Marinette her powers. And Plagg could befriend Sebastian the crab and together they cause some comical chaos while also helping to protect the underwater realm from threats. The characters of Miraculous Ladybug could bring their own unique powers and personalities to the story of The Little Mermaid, adding new layers of adventure and friendship.

Tikki and Plagg could have interesting roles too. Tikki, being the kwami of creation, could help Marinette come up with ways to interact with the Phantom and the other characters in the Phantom of the Opera world. Plagg, on the other hand, might be a bit more mischievous. He could accidentally cause some chaos that either makes the situation more difficult or surprisingly helps in some way. For instance, he might steal the Phantom's mask as a joke, which could lead to a whole new set of events.

Marinette could be Juliet. She's often shy and has a secret identity, much like Juliet had to keep her love for Romeo a secret. Adrien as Romeo would be a natural fit. He's charming and from a different 'world' in a sense, just as Romeo was from the Montague family. Chat Noir could be Romeo's more flirty and adventurous side, while Ladybug is Juliet's strong - willed and responsible side.

Well, Ladybug could be seen as a new type of Gem. Her powers are magic - based, similar to the powers of the Gems. She might be mistaken for a powerful new Gem at first. Cat Noir could be like a fusion of sorts, with his cat - like abilities and charm. He could team up with Amethyst, for example, as they both have a bit of a wild side.

One idea could be that Marinette, as Ladybug, gets transported to the world of Beauty and the Beast. She could use her powers to help the Beast break the curse in a unique way. Maybe she creates a special charm with her Miraculous that has an impact on the enchanted objects.

Befana can be a magical helper. In fanfiction, she often uses her powers of flight and gift - giving to assist Ladybug and Chat Noir. For example, she might give them a magical item to defeat a particularly tough akuma.

Well, perhaps she's a mentor figure. Since she has a lot of experience in the superhero/villain world in the Marvel universe, she could teach Ladybug and Chat Noir new fighting techniques and strategies to outwit their enemies.

Well, Harry in the role of the Beast would be more territorial about Hogwarts, which he now sees as his own 'castle'. He would be hesitant to let Hermione in at first, but slowly open up as he realizes she's different. His scar could be part of his 'beastly' appearance, adding to his sense of being different. Hermione would fit the Beauty role by being the one who brings light into Harry's dark world. She would be patient with him, using her logical mind to try and understand his situation, and at the same time, she would be drawn to his inner strength that she can sense beneath his exterior.

Marinette's friends, like Alya, would be heartbroken. Alya, being Ladybug's biggest supporter, would probably feel a sense of loss and confusion. She might start to investigate Ladybug's death, trying to figure out what really happened. The other classmates would also be affected, with the mood at school becoming very somber.

Well, Harry could be the Beast. He has that scar which could be seen as a mark of his 'beastliness' in a way. And Hermione could be like Belle, intelligent and curious, and she might be the one to see past Harry's outward appearance (the scar and the effects of the curse) and fall in love with him for who he really is.
