A thief OC in 'Miraculous Ladybug' fanfiction can be developed by giving them a backstory. Perhaps they grew up in a poor family and had to steal to survive, and now it's become a way of life. But they also have a sense of justice. They might only steal from the rich or those who have wronged others. Their code of ethics could be an interesting aspect to explore. Also, think about how they interact with the Miraculous world. Do they believe in the power of the Miraculouses? Are they envious of Ladybug and Chat Noir's powers? All these elements combined can create a well - developed thief OC.
One idea for a 'Miraculous Ladybug' thief OC fanfiction could be that the thief OC is stealing artifacts that are actually magical items related to the Miraculouses. The OC could be doing it for a noble cause, like trying to prevent a greater evil from getting their hands on them. Maybe they have a tragic backstory that led them to this path. For example, their family was wronged by someone who wanted to use the Miraculous for bad, and now they are trying to keep the artifacts safe by stealing them from those who would misuse them.
A new character who is a skilled acrobat could be a great thief. They could use their acrobatic skills to easily get in and out of places unnoticed. Their backstory could be that they grew up in the circus and had to turn to thievery due to some misfortune.
Another way is to have the Kwami OC interact with the existing Kwamis in the Miraculous Ladybug universe. If your Kwami OC is Ember, which has the power of fire, it could meet Tikki and Plagg. They could have a conversation about how their powers are different yet related. This kind of interaction can add depth to your fanfiction.
Chat Blanc's character development in Miraculous Ladybug fanfiction can vary widely. Sometimes, he becomes more vengeful as the story progresses, blaming Ladybug for his state. Other times, he realizes his own wrongdoings and tries to fight against the dark force that has corrupted him. Writers often use his relationship with Ladybug as a key factor in his development, whether it's through love, friendship, or a sense of duty.
Give your OC a strong motivation. It could be something like avenging a loved one who was hurt by an akumatized villain. This will drive their actions throughout the story.
To create a great Miraculous Ladybug Akuma OC fanfiction, start with a well - thought - out OC. Consider their dreams and fears. Let's say your OC is a fashion designer who dreams of showing at Paris Fashion Week but is constantly rejected. When they're akumatized, their power could be to turn all fashionable clothes into rags. Then, make the story engaging by having Ladybug and Chat Noir face difficulties in dealing with this new akuma. They might have to seek help from other characters or use new strategies. Also, don't forget to add some emotional depth to the story, like showing how the OC feels during and after being akumatized.
Let's make a Kwami named Luma. Luma could be a Kwami related to stardust. Its Miraculous could be a star - shaped hairpin. The superhero with this Miraculous would be able to fly faster than normal superheroes, and also have the ability to create a shield made of stardust that can protect from most attacks.
Title: 'The Akuma of the Mysterious OC'. In this fanfiction, my OC, Lila, is a shy artist in Paris. One day, she gets akumatized because her art was rejected for an important exhibition. Hawkmoth takes advantage of her sadness and anger. As the Akuma, she gains the power to turn all art in Paris into chaos. Ladybug and Chat Noir must find a way to save her and Paris.
If Alya gets isekaied, she could develop into a more strategic thinker. In the Miraculous Ladybug world, she's mainly an observer and reporter. But in an isekai world, say one full of complex puzzles and mysteries, she might have to use her intelligence in a different way. She could learn to analyze situations more deeply and come up with plans to overcome obstacles. This would be a big change from her role in the original story where she's often just reacting to Ladybug and Chat Noir's actions.
Lila is often a popular thief character in fanfictions. Given her manipulative nature in the original series, it's easy to imagine her taking on the role of a thief. She could be stealing things to frame Ladybug or gain more power within the school or the city.
