The main characters are Ladybug and Chat Noir. But don't forget about Hawk Moth, the villain. In some fanfictions about the big reveal, Hawk Moth might find out their identities during or after the reveal, which changes the whole dynamic of the story. He could use this knowledge to try and defeat them in a more devious way, so his presence is still very much a part of the plot even though the focus is on the reveal between Ladybug and Chat Noir.
Most likely Ladybug and Chat Noir would be the main characters as they are central to the Miraculous Ladybug series. They would probably be the ones whose identities are at risk of being revealed during the dodgeball game.
Ladybug and Chat Noir are obviously very popular. Since the whole concept of 'the reveal' usually revolves around them, fans are always eager to read about how their identities are finally exposed to each other.
Some authors make it a very emotional and heart - warming moment. The characters might be shocked at first, but then quickly feel a deep sense of relief and connection. They could start crying tears of joy as they realize how much they mean to each other in both their superhero and civilian identities.
In some fanfictions, one interesting plot development could be that Ladybug and Chat Noir accidentally reveal their identities during a battle. For example, their Miraculous might get damaged and they transform back in front of each other.
The comic probably has exciting adventures and maybe some big secrets being uncovered about the characters in the Miraculous Ladybug world.
One great 'Miraculous Ladybug Class Reveal Fanfiction' is 'Class Secrets Unveiled'. It beautifully shows how the classmates react when Ladybug and Chat Noir's identities are revealed within the class. The characterizations are on point, staying true to the show's personalities.
The 'Miraculous Ladybug Dodgeball Reveal Fanfiction' might focus on the characters' relationships while playing dodgeball. For instance, how they interact with their classmates during the game. It could be that Marinette (Ladybug) has a moment of clumsiness on the dodgeball court that nearly gives her identity away, or perhaps Adrien (Chat Noir) uses his cat - like reflexes a bit too well and makes people suspect. And then there's the big reveal moment which could be filled with drama, shock, and a whole new set of challenges for the characters.
Well, in some fanfictions, a plot twist might be that there's a third party who already knew their identities all along and has been manipulating events. This third party could be using their knowledge to either bring them closer or drive them apart for their own motives. Also, there could be a plot twist where the big reveal is actually a false one, set up by Hawk Moth to deceive them and gain an advantage in his fight against the heroes.
Marinette is often really well - written in these fanfics. Since she has such a complex personality as both a clumsy girl and a powerful superhero, fanfic authors can explore different aspects of her character. Chat Noir / Adrien is also great. His charm and his insecurities can be delved into deeper after the reveal. And sometimes Alya, as Marinette's best friend, is written very well. She can be the one who helps Marinette deal with the new situation after the reveal.
One I really like is 'When Laughter Leads to the Reveal'. In this fanfiction, there's a new villain who has the power to make people laugh uncontrollably. Ladybug and Chat Noir are affected and in their fit of laughter, they end up accidentally revealing their identities to each other. The story then focuses on how they deal with this new knowledge while still having to fight off the villain and protect Paris.
