Adrien and Marinette are the most prevalent. Since they are the main characters in Miraculous Ladybug, fans are drawn to the idea of them in an arranged marriage. It's exciting to think about how Marinette's secret identity as Ladybug would factor into the arranged marriage. Also, Alya and Nino can be a popular pairing in these fanfictions. Their relationship in the show is so warm and friendly that seeing them in an arranged marriage situation could be really interesting. It could show how their relationship deepens and changes. Additionally, Kagami and Felix could be an interesting pairing in arranged marriage fanfiction. Kagami's strong - willed nature and Felix's mysterious personality would create a lot of tension and intrigue in an arranged marriage story.
Adrien and Marinette are definitely one of the most popular pairings. Their relationship in the original show already has a lot of chemistry, and in arranged marriage fanfictions, it adds a whole new layer of complexity. Another popular pairing could be Kagami and Adrien. Given Kagami's more traditional upbringing, an arranged marriage scenario seems more likely for her character, and fans like to explore how she and Adrien would handle such a situation. There's also the pairing of Marinette and Luka which some fans might explore in an arranged marriage context, especially since Luka has such a calm and understanding personality which could be interesting in an arranged marriage dynamic.
The most popular pairing is definitely Ladybug and Chat Noir. Their dynamic as superhero partners, with the unspoken feelings between them, makes for a very appealing relationship in fanfiction. Another popular one is Marinette and Adrien. Since they are the civilian identities of Ladybug and Chat Noir, exploring their relationship outside of the superhero world is also quite interesting for fans.
Ladybug and Iron Man could be really cool. Iron Man is a tech genius, and he might be super intrigued by Ladybug's magic - based powers. He could try to analyze her Miraculous while she shows him that there are things technology can't fully understand. And Cat Noir with Black Widow would be a fun pair. Black Widow's stealth and combat skills combined with Cat Noir's acrobatic abilities and his cat - like reflexes would make for some great action scenes.
In many such fanfictions, a plot could be that the arranged marriage is arranged by a magical entity. Maybe it's an old kwami who believes that uniting these two particular holders of the Miraculous through marriage will bring balance to the world. So the two main characters, like Marinette and Adrien perhaps, have to navigate this strange situation. They might be hesitant at first but then start to see the potential benefits not just for themselves but for the greater good. This could involve them working together more closely as superheroes and as a couple in the arranged marriage, which in turn helps them defeat villains more effectively.
Hawk Moth is another character that shows up a lot in fanfiction. Writers like to explore his motives more deeply, or come up with scenarios where he has a change of heart or forms an unexpected alliance. His complex character makes him an interesting subject for fanfiction writers to play around with.
Aside from Ladybug and Chat Noir, Hawk Moth is quite popular in fanfiction. He is the main villain, and many fanfiction writers like to explore his backstory and motives further.

And of course, Adrien, who is Chat Noir, is a fan favorite due to his charming personality both as a superhero and as a civilian.
Marinette is also very popular. Fanfiction often delves into her life as a normal girl, her struggles with school, her crushes, and how she balances being Marinette with being Ladybug. Her clumsy but endearing personality gives a lot of room for interesting storylines.
One popular pairing is Draco and Hermione. It creates an interesting dynamic as they come from different backgrounds and have had a somewhat adversarial relationship in the original series. Another is Draco and Astoria. Since they are somewhat connected in the original lore, it's a natural pairing for many fanfiction writers. And Draco and Ginny can also be a pairing in some arranged marriage fanfictions, which offers a different take on the relationships within the wizarding world.
Ladybug and Batman would be an interesting pairing. Ladybug's positive and hopeful nature could contrast with Batman's brooding and dark approach. They could learn from each other's detective skills, with Ladybug showing Batman that there's always a way to solve a problem without being too grim, and Batman teaching Ladybug some more strategic combat moves.
Cat Noir and The Flash would be a really cool pairing. The Flash's super - speed and Cat Noir's acrobatic and cat - like agility would make for some amazing action scenes. They could also have some fun banter as they race around, with Cat Noir's flirty personality and The Flash's quick - witted remarks. And they could both learn about different ways of using speed in combat and getting out of tight situations.
