Don't make the story revolve solely around the Mary Sue. Incorporate the existing characters and their storylines from the Percy Jackson series. Let them interact with the Mary Sue in a way that feels natural. For example, Percy might be initially suspicious of this new character who seems to have a lot of power and not much of a backstory at first.
Work on the character development of the Mary Sue. Instead of just having her show up and be amazing from the start, let her grow and learn throughout the story. Maybe she starts off with a basic power but through her adventures in the Percy Jackson world, she discovers new aspects of her power and also learns about her own limitations.
First, don't make the Mary Sue character overpowered in every way. Give her some flaws, like maybe she's not great at making friends easily despite her powers. Second, don't have all the Avengers fawning over her right away. Build relationships more slowly and realistically. For example, some Avengers might be initially suspicious of her. Third, make the plot revolve around more than just the Mary Sue. Let the original Avengers also have important roles and development in the story.
Focus on their character development. Show how they grow and change over time. For example, instead of just having them immediately fall into each other's arms, show Percy becoming more confident in his emotions and Annabeth learning to be more open. This will make their intimate moments feel more earned and natural.
First, focus on their personalities. Flareon is often depicted as energetic and warm - hearted, while Glaceon is more cool and collected. Use these traits to drive their actions and decisions in the story. Avoid overusing clichés like instant love at first sight. Instead, let their relationship develop gradually through shared experiences, like facing a difficult battle together or helping each other through a tough situation. Also, add some unique elements to the story, such as a special location or an unusual item that plays an important role in their relationship.
First, really understand the characters of Itachi and Konan. Itachi is a complex character with a lot of internal conflict, and Konan is strong - willed. Don't just jump into the 'lemon' part. Build up their relationship gradually, like showing how they first meet and start to trust each other.
First, focus on their personalities. Riku is often seen as more brooding and Kairi is quite gentle yet strong. Use these traits to build their interactions. For example, show how Riku's protectiveness towards Kairi can be a driving force in their relationship.
Focus on the unique aspects of their relationship. For example, the contrast between Lydia's human nature and Beetlejuice's otherworldly chaos. Don't rely too much on overused romantic clichés like instant love at first sight. Instead, build their relationship gradually through shared experiences, like dealing with the strange creatures in the Netherworld together.
Avoid using overused clichés. Instead of the typical 'love at first sight' scenario, build a slow - burning relationship. For example, start with mutual respect for each other's skills and leadership. As they interact more, show how they start to notice little things about each other that gradually lead to deeper feelings. Also, use vivid descriptions of their surroundings and the events they are in to add depth to the story.
Keep the characters' personalities intact. Ichigo is a brave and head - strong character, and Rukia is cool - headed. Don't make them act out of character just because of the pregnancy. For example, Ichigo would still be ready to fight if needed, even while being concerned about Rukia and the baby.
Avoid using overly flowery language. Keep the dialogue realistic. In a Ghost x Reader fanfiction, Ghost is likely to be a tough character. So, his words should reflect that. Also, add some action or a plot twist. Instead of just a lovey - dovey story, maybe there's a mission they have to go on together. This makes the story more engaging and less cheesy. For example, they could be on a mission to save a group of people and their relationship deepens during that time.
Firstly, read a lot about Percy and Sally from the official books. This will give you a good feel for their voices and personalities. When writing the fanfiction, put them in situations that are believable for them. If you're writing a lemon, make sure the emotions and the relationship development lead up to it in a way that makes sense for their characters. Percy might be a bit hesitant at first due to his respect for Sally, and Sally might be the one to initiate some deeper emotional exchanges based on her more mature nature.
