One common theme is the exploration of different powers. Since Percy has his own set of powers and Venus is a powerful goddess, their interactions often involve discovering new abilities or combining their powers. For example, in some fanfics, they might use Percy's water - related powers along with Venus's love - related powers to defeat a common enemy.
Well, there's this fanfiction called 'Sailor Mars and Sailor Venus: A New Chapter'. It takes an interesting approach where they go on a journey to discover a new power source together. The author does a great job of building their relationship in a unique way. Also, 'The Red and the Gold' is a fanfic that focuses on their different personalities and how they complement each other in the fight against evil.
Another place is FanFiction.net. There are many different types of fanfictions on this site, so it's worth checking for 'reader x venus' fanfiction. Just use the search bar and type in the relevant keywords.
The fanfic could explore virus evolution through the eyes of a scientist character. This scientist could be studying the genetic makeup of the coronavirus and flu virus over time. As the story progresses, they notice small changes that gradually accumulate into significant evolutionary leaps. The scientist might then have to race against time to develop new treatments or vaccines as the viruses become more and more different from their original forms, all while dealing with the political and social implications of their findings.
In a Virus X and Trip fanfic, Trip could be a fearless explorer who stumbles upon Virus X in a hidden jungle. He then has to figure out a way to not get infected and also how to warn the world about it.
They could start as enemies. Kunzite is a powerful minion of the Dark Kingdom, and Sailor Venus is a Sailor Guardian. Their first encounter might be intense, full of magical attacks and defenses. But as the story progresses, they find out that there is a third, more powerful enemy emerging that threatens both their worlds. This forces them to work together, at least temporarily.
You can start by looking on fanfiction.net. It has a large collection of Sailor Moon related fanfics, including many focused on Sailor Mars and Sailor Venus. Another good place is Archive of Our Own (AO3). It has a well - organized tagging system that makes it easier to find the specific fanfics you're interested in.
One possible plot could be a story where Aoba, Trip and Virus are in a post - apocalyptic world. Aoba might have some special ability that Trip and Virus are both intrigued by. They could start as rivals, competing for Aoba's attention or the power he holds. Then, as the story progresses, they realize they need to work together to survive against a common enemy, like a powerful and evil organization that wants to use Aoba's ability for their own dark purposes.
To develop Aoba, give him a goal. It could be something like finding a cure in a virus - ridden world if that's the setting. Then show how Virus and Trip either help or hinder this goal. Virus can be developed by showing his complex relationship with power. Is he power - hungry or just trying to survive? Trip can be developed through his relationships. He might be the one who tries to bring Aoba and Virus closer together.
