Well, if Annabeth dies in a fanfic, it would be a really tragic turn. Percy would be completely devastated. He's been through so much with her, and she's not just his girlfriend but also his partner in all their adventures. Their relationship has been a central part of the Percy Jackson series, so her death would change the whole dynamic. Fans would be heartbroken too, as Annabeth is a very popular character. It could lead to Percy going on a dark path, seeking revenge or just shutting down completely.
One popular 'Percy Dies' fanfic could be 'The Fall of Percy Jackson'. It explores the aftermath of his death on the other characters.

Maybe in the fanfic, Percy's death could be a sacrifice to save Zoe. This would then lead Zoe to live her life in a way that honors Percy's sacrifice.

Annabeth is often the one to save Percy. She's smart and resourceful. For example, she might use her knowledge of architecture to find a way out of a collapsing building that Percy is trapped in. Or she could use her strategic thinking to outwit a monster that has Percy at its mercy.
Percy often becomes more somber. He may lose some of his initial naivete. For instance, he might be more cautious in his actions, thinking twice before jumping into a fight like he used to.
Percy would be completely devastated. He might go into a state of shock at first, unable to believe that Annabeth is really gone. Then he could become filled with rage, vowing to take revenge on whoever or whatever was responsible for her death.
In this fanfiction, Percy might sacrifice himself in a grand battle. He could be facing a powerful enemy that was about to strike Zoe. Percy, being the heroic type, jumps in front of Zoe at the last moment. His last thoughts could be of his friends and all the adventures he had. Zoe, in turn, is left with a deep sense of guilt and sorrow, vowing to carry on Percy's legacy. She might become even more determined to fight for the cause they both believed in, all while mourning the loss of her dear friend.
In this kind of fanfiction, it's often a very tragic and heroic concept. Percy sacrificing himself to save the seven would be a huge shock to the other characters.

In this type of fanfiction, it's a really interesting concept. One possible scenario could be that Percy's death is a heroic sacrifice.
