In a fanfiction, Medusa could capture Pit and instead of killing him immediately, she tries to corrupt him. She might use her powers to show Pit false visions of a world where the gods have failed everyone. Pit would then have to resist her influence and find a way to escape.
Another fanfiction could be set in the past, showing how Medusa and Pit's relationship started. It could delve into their first encounters, how Medusa's jealousy or hatred towards Pit began, and how Pit initially perceived her as an enemy. This backstory could add depth to their characters and their relationship in the overall Kid Icarus lore.
One common theme is the exploration of their relationship, whether it's a deep friendship, a brotherly bond or a complex rivalry. Another theme is their growth as characters, like how they become stronger together.
One possible fanfiction could be about Pit from Kid Icarus encountering a dragon in a world where Transformers (TF) also exist. Maybe the dragon has some sort of connection to the technology of the Transformers. For example, it could be a mechanical dragon that Pit has to fight or team up with depending on the plot.
One popular Kid Icarus Pit x Dark Pit fanfiction is 'Bond Beyond the Battle'. It explores their relationship in a post - war scenario, delving deep into how they support and understand each other on a more personal level.
Another theme is self - discovery. As they interact more, both Pit and Dark Pit often discover new aspects of themselves. For example, Dark Pit may find more of his 'good' side through his relationship with Pit, and Pit may become more confident in his own abilities. It's all about how their relationship impacts their individual growth. This can be seen in various fanfictions where they face challenges that force them to look within themselves. Some fanfictions also have a theme of redemption, especially for Dark Pit who was initially more of an antagonist. Through his relationship with Pit, he gets a chance at redemption and to be seen in a new light.
A prevalent theme is the power dynamics between Pit and Phosphora. Given their different powers in the game, fanfic authors like to play with how these powers interact when they are in a relationship. Also, there's often a theme of redemption or growth. For instance, if one of them has made a mistake in the game's lore, the fanfiction might explore how they redeem themselves in the eyes of the other. And of course, there's the classic theme of love and how it develops between the two characters in a way that might not be fully explored in the original game.
One idea could be that Pit is kidnapped and Hades tries to corrupt him. Maybe Hades offers Pit power in exchange for his loyalty. Pit, being the heroic character, resists but has to find a way to escape while also facing the internal struggle of being tempted by such power.
Redemption is also a theme that can be found. Dark Pit, being a sort of 'dark' counterpart, might be on a journey of self - discovery or redemption in some fanfics. Pit could play a role in this, either as an influence or a guide. This theme adds depth to the characters and their relationship, as it explores the idea of change and growth within the context of their unique situation in the Kid Icarus lore.
There's a fanfiction called 'Pit and Dark Pit: United Front'. In this story, they face a powerful common enemy and their bond grows stronger as a result. It's really exciting to read how they work in tandem. Also, 'The Dark to His Light' is a good one which focuses on the contrast and harmony between them.
