The world of Eureka 7 itself is rich in lore and settings. Fanfiction writers can use this backdrop to create all sorts of scenarios for Renton and Eureka, whether it's exploring new parts of the world or dealing with the aftermath of the main story's events. For example, they could be in a situation where they have to protect a new discovery in the world, and how they handle it together shows a new side of their relationship. Also, the idea of their love in the context of the often - dangerous and strange world they live in adds an extra layer of intrigue.
There's also 'Renton and Eureka's Adventure' where they embark on a new journey together, facing challenges and growing closer in the process. It has some really nice character development for both of them. In this fanfiction, the author does a great job of capturing the essence of their relationship and how they support each other through difficult times.
One great eureka fanfiction could be 'The Alternate Eureka'. It explores a parallel universe where the scientific inventions in Eureka have different implications. Another is 'Eureka: The Lost Years' which fills in the gaps of the characters' backstories.
One common theme is scientific discovery. Since the town is full of brilliant minds and crazy experiments, many fanfictions explore new scientific concepts. Another is the sense of community. Despite all the chaos, the people in Eureka come together.
One idea could be a crossover between Eureka and a superhero universe. The brilliant minds of Eureka could collaborate with superheroes to solve a global threat that combines advanced science and superhuman abilities. For example, they might work together to stop a villain who is using a combination of alien technology and superpowers to take over the world.
A really cool Eureka Seven fanfiction idea could be centered around a new type of LFO that is discovered. This LFO could have unique abilities that no one has ever seen before. The story could follow a young pilot who discovers this LFO and has to learn how to control it while also facing the threat of an unknown enemy. Another concept could be a fanfiction that dives deep into the cultural aspects of the different races in the Eureka Seven universe. How do they interact? What are their traditions? And how do these things affect the overall story?
One common theme could be the challenges they face as a couple with an upcoming baby. It might include how they adjust to the new situation, both emotionally and practically. Another theme could be the reaction of their friends and family in the Eureka Seven universe.
One common theme is their relationship development. Writers often explore how they grow closer and understand each other better over time. Another theme can be their adventures together, building on the events from the original series and creating new scenarios for them to face.
One of the common themes is the exploration of their unique bond. Given their different backgrounds in the original story, fanfiction often dives deeper into how they bridge that gap. Also, the theme of protecting each other is prevalent. In many stories, they will go to great lengths to keep the other safe. And there's also the theme of self - discovery. As they are in a relationship, they discover new sides of themselves. For example, Renton might find a new sense of courage because of his love for Eureka, and Eureka might discover more about her humanity through her relationship with Renton.
