Another way their relationship could develop differently is if they both realize the error of their ways and decide to work together to fix the mess they've made. They could start by making amends with Adrien and then use their resources and knowledge to help Ladybug and Chat Noir protect Paris more effectively.
A different development could be that they fall out completely. Nathalie might realize that Gabriel's obsession with getting the Miraculous is too dangerous and she decides to leave his side. This could lead to her becoming an ally of the heroes and working against Gabriel, which would be a huge shift in the story.
In many Miraculous Ladybug fanfictions about Nathalie and Gabriel, their relationship is complex. They are often depicted as having a deep connection due to their shared goals regarding the Miraculouses. Nathalie is very loyal to Gabriel in the series and in fanfictions this loyalty is explored further. Sometimes it's a one - sided love from Nathalie's side, while other times it's a more mutual understanding of their partnership in the pursuit of power.
Fanfiction about Nathalie and Gabriel often explores their backstories. Maybe there was a time before they got involved in the Miraculous hunt when they had a more normal relationship. In some stories, the writers might give Nathalie a more sympathetic angle, showing that she got dragged into Gabriel's dark plans against her better judgment. This adds depth to both characters and makes for some really engaging reading.
Nathalie plays a crucial role in Gabriel - centric fanfictions. She is often the one who keeps Gabriel's operations running smoothly. Her knowledge and skills are essential for his plans related to the Miraculouses. For example, she might be the one who researches about the powers of different Miraculouses or manages the day - to - day tasks that allow Gabriel to focus on his bigger goals.
In the fanfiction, their relationship could develop more quickly. Instead of the slow build - up in the show, they could have a heart - to - heart conversation earlier. For example, Kagami could directly tell Adrien that she likes him more than just a friend. This would force Adrien to confront his feelings for her sooner, rather than being so focused on Ladybug all the time.
They interact in various ways. In some fanfictions, Nathalie is very submissive to Gabriel's commands. She just follows his orders without question as she is dedicated to his cause. For instance, when it comes to finding the Miraculous, she does whatever he asks.
One idea could be that they discover a new Miraculous together. They might be on a mission to find it and in the process, their relationship deepens as they face various challenges. For example, they could encounter an enemy who is also after the same Miraculous and they have to work together to outwit them.
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.
It could be Lila. Since she is always causing trouble in the series, in a Nathalie - centered fanfiction, she could target Nathalie as well. Maybe she tries to frame Nathalie for something to get closer to Gabriel or to get rid of Nathalie who she sees as an obstacle to her plans.
The plot also matters. It could be a story that takes place within the existing Miraculous Ladybug universe but gives Nathalie a more central role. Maybe she has to make a difficult decision that could change the course of events in the show. Good character development for Nathalie, as well as interactions with other characters like Adrien and Marinette, can make the fanfiction great.
In fanfiction, perhaps Alix helps Kim train for a big sports event. During this time, they start to understand each other's dreams and fears better. Kim realizes that Alix is not just a tough - talking girl, and Alix sees that Kim has more depth than his jock - like exterior. This new - found understanding could lead to a deeper friendship or even a romantic relationship.
