How about a fanfic where Calhoun and Fix - It Felix swap abilities? Calhoun suddenly has Fix - It Felix's ability to fix things, and he has her combat skills. They have to navigate their daily lives in the game with these new abilities, which would be really funny at times but also a great way to see them understand each other's roles better. They would have to learn how to use their new skills to solve problems that they usually wouldn't face in their normal state.
A really interesting fanfic could be set in a world where the game has glitched, and Calhoun and Fix - It Felix have to figure out how to fix it while also dealing with their own personal issues. Calhoun might be struggling with her fear of the glitches getting out of control, and Fix - It Felix could be trying to prove his worth outside of just fixing things. They work together to not only save the game but also themselves, and it would be a great exploration of their characters in a more complex situation.
I'm not sure about a specific 'lemon' fanfiction as that often involves inappropriate or adult - themed content. However, there are many great clean Fix - it Felix and Calhoun fanfictions out there.

One common theme could be their relationship growth. Even without inappropriate elements, their unique dynamic can be explored, like how they support each other in the game world.
One popular fanfiction could be 'Felix and Calhoun's New Adventure'. It might explore their relationship further in a new setting, like a different video game world.

For Felix, he could be a rather sensitive and introverted character. His attraction to Bridgette's voice might be because he's more attuned to subtleties in sound due to his own quiet nature. He may be shy in expressing his feelings directly but is very passionate about this voice kink. Bridgette, on the other hand, might be an extroverted and confident person. Her voice could be a reflection of her outgoing personality, and she may be used to getting attention, but not in the way Felix is giving it.
Felix and Oswald interact in a rather complex way. They often start off on the wrong foot. Felix might be more cautious and reserved, while Oswald could be more impulsive. For instance, Oswald might rush into a situation in the ink - filled corridors, and Felix would be hesitant, causing some tension between them.
One common theme is the exploration of their contrasting personalities. Felix is often portrayed as more aloof and mysterious, while Kagami is strong - willed and direct. Their differences create an interesting dynamic that fanfic authors like to explore.
Friendship is a very common theme. They start as arcade characters with different personalities but over time, they build a strong bond of friendship which is often explored in these fanfics.
