Well, in some Percy Jackson bow fanfiction, the bow might be a family heirloom passed down through generations of demigods. For example, a story could revolve around a character who didn't know they were a demigod until they found this old, dusty bow in their attic. The bow then reveals its true powers and leads the character on an adventure to Camp Half - Blood. Or perhaps a fanfic where the bow is cursed, and the main character has to find a way to break the curse before it causes chaos in the camp. There are so many possibilities.
One possible interesting story could be Percy using the bow to defend his friends in a dangerous battle. Maybe he discovers some unique abilities of the bow that help him turn the tide.
In fanfiction, Percy using a bow has the advantage of being able to cover more ground. With a sword, he has to be in close proximity to his enemies. But with a bow, he can target enemies that are far away. This can be crucial in situations where there are traps or dangerous areas between him and his foes. Also, the bow can be a more silent weapon compared to his sword, allowing him to take out enemies stealthily in some scenarios.
One interesting fanfiction could be about Sally's early adventures before Percy was born. It might explore her relationship with Poseidon in more depth.

And there are also fanfictions that rewrite certain events from the original series with a different perspective from Sally's point of view.

In fanfiction, Percy could use a bow in a way that's related to his demigod abilities.

There are fanfictions where Percy's girlfriend is an original character created by the writer. For example, she could be a daughter of a minor god who has unique powers. The story might focus on how she fits into Percy's world, his relationship with his friends, and how they all deal with the threat of an ancient prophecy. It often adds a fresh perspective to the Percy Jackson universe.
