Hunnigan could be a great addition. She could provide Leon with information and support from the outside, and her presence could add some tension as she might be suspicious of Ada's motives. Another good character is Wesker. His past connection to Ada could create more drama and conflict in the story. He could be a shadowy figure trying to manipulate the situation between Leon and Ada.
One common theme is the struggle between love and duty. Leon and Ada are often on different sides in the official stories, so fanfics explore how their feelings for each other play out against their respective missions. For example, in many fanfics, Ada has to make a choice between helping Leon and fulfilling her own tasks.
Well, there are several interesting Ada and Leon fanfictions. For example, 'The Encounter in the Shadows' is a fanfic that explores their first meeting from a different perspective. It shows how their initial distrust slowly turns into a begrudging respect. 'Ada and Leon: A New Alliance' is also good. It's set in a world where they have to team up against a new, powerful enemy and in the process, their relationship evolves in unexpected ways. Then there's 'The Lost Chapters of Ada and Leon' which fills in the gaps of their story that the official games might have left out.
There's also 'Ada and Leon: Shadows of Raccoon City'. This fanfic takes place after the events in Raccoon City. It shows how their paths cross again and how they deal with the lingering traumas from that time while still being drawn to each other. It's a really engaging read as it adds new layers to their relationship.
One common theme is the unspoken attraction between them. Their relationship in the games is full of mystery and tension, and fanfiction often delves deeper into that.
In some fanfictions, Leon and Ada's relationship is often filled with mystery and tension. Since Ada is a complex character, her interactions with Leon can range from being somewhat antagonistic to having a deep, unspoken connection. When it comes to a 'baby' in the fanfiction, it could be used as a plot device to either bring them closer or create more conflict. For example, if they were protecting the baby together, it would force them to work in unison and perhaps explore their feelings more openly.
One key moment was their initial meeting in Raccoon City. It was the start of their connection. Another important moment was when Ada saved Leon in a dangerous situation, which deepened his feelings for her. Also, the times when they had to choose between their own missions and their feelings for each other were crucial in their love story.
Good character development makes a great Ada Wong and Leon fanfic. Writers need to stay true to their personalities. Leon's sense of justice and Ada's mysterious allure should be well - presented. Also, an exciting plot is key. Whether it's a new bio - horror threat or a complex political conspiracy, it should keep readers on the edge of their seats.
I really like 'A New Beginning' in the 'leon kennedy x claire redfield fanfiction' genre. It starts with them meeting in an unexpected situation and then gradually shows how their relationship deepens. The action scenes are well - integrated with their growing connection, making it an exciting read.
