One common theme is the idea of redemption. Zane often has a bit of a troubled past in the series, and in fanfics, his relationship with Aphmau can be a path towards redemption. Another theme is the discovery of love. They might start off as just friends or even enemies, and then gradually realize their feelings for each other.
One common theme is the enemies - to - lovers trope. Given their different personalities in the original content, it's a popular choice for writers to start with them at odds and then develop a romantic relationship.
The theme of friendship - to - lovers is also quite prevalent. They are often part of a group of friends in the fanfiction world. Their relationship evolves from just being friends within the group to something more romantic, which makes for a very heartwarming story arc.
I think 'Gene and Zane: A Tale from Aphmau' would be a great title. It has a bit of a classic feel to it, like it's going to be a story that unfolds in the Aphmau universe. It gives the impression that there is a story to be told about these two characters, and it makes the reader curious to know what that story is. Maybe it could be a story of friendship, or perhaps a story of how they overcome some sort of obstacle together.
One popular zane x aphmau fanfic is 'A New Beginning'. It explores their relationship in a unique way, with lots of sweet and heart - warming moments. Another great one could be 'Unexpected Love'. It takes the characters on an adventure where their feelings for each other start to develop in unexpected situations.
You can try websites like Archive of Our Own (AO3) or FanFiction.net. AO3 has a large collection of fanfics and a good search function to help you find Aphmau x Zane fanfics specifically. FanFiction.net also has a wide range of fan - created stories, but the quality may vary more.
There's a fanfiction titled 'Unexpected Love'. In this story, Zane and Kawaii Chan find themselves in various situations that force them to confront their feelings for each other. It has a really engaging plot that keeps you hooked from start to finish. The descriptions of their emotions are quite vivid.
One common theme is friendship. Since Zane and Chan are often depicted as friends or more, exploring their bond of friendship is a popular theme. Writers like to show how they support each other through different situations.
