Another theme could be love at first sight. It's a popular trope where the reader and Brandon Lee's character fall for each other immediately. And of course, there can be themes of mystery, where the reader gets involved in some sort of mystery that Brandon Lee's character is trying to solve.
You can try searching on popular fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfictions across various fandoms, and there's a good chance you'll find some great Brandon Lee x Reader fanfictions there. Another option could be FanFiction.net, though the quality can vary more on that site.
One common theme is love and romance. Since they are a couple, most fanfictions explore their relationship in different ways, like how they fall in love or keep their love alive.
Music is also a recurring theme. Given that Marshall Lee is associated with music in his character, many fanfics incorporate music into the story. For example, the reader might learn to play an instrument from Marshall Lee or they might attend a music concert together. And of course, there's the theme of self - discovery. As the reader character interacts with Marshall Lee, they often learn more about themselves, their strengths, and their desires.
A theme of self - discovery might also be present. As they interact, both Bloom and Brandon Lemon could be on a journey to understand themselves better. For example, Bloom might learn something new about her powers or her place in the world through her relationship with Brandon Lemon. There could also be themes related to friendship, where their relationship starts as friends and then may or may not develop into something more.
The theme of redemption also appears sometimes. Gaara's past actions and his journey to redemption can be intertwined with his relationship with Lee.

Friendship is a very common theme. Stories often explore how Eddy and Lee support each other through thick and thin.
One common theme is friendship evolving into something deeper. Since they start as comrades and rivals, many fanfictions explore how that relationship can transform over time.
Love, either platonic or romantic, is also a frequent theme. Sometimes it's a slow - burn type of love where they don't realize their feelings for a long time. Other times it's a more immediate connection that they have to navigate through various obstacles in the story.
One common theme is rivalry. Since they are often opponents in the game, this rivalry can be explored in different ways in fanfiction, like a friendly competition or a more intense, grudging rivalry that might turn into respect or even friendship.
The theme of mutual respect is prevalent too. They come from different villages with different values, but in the fanfictions, they gradually respect each other's ways and grow together as a result.
