The future of the baby is full of possibilities. Given that Annabeth is pregnant and Percy has passed away, the baby will be raised in a world where it has to face the legacy of a heroic father it will never know. If the baby is a boy, he might be inspired to follow in Percy's footsteps and become a great defender of the demigod world. If it's a girl, she could grow up to be as smart and brave as Annabeth. Annabeth would surely instill in the baby values like courage, loyalty, and wisdom. And who knows, the baby might even discover new powers or abilities that are unique to it, and use them to make a mark in the world of demigods or in the mortal world if it chooses to interact with it.
Well, Annabeth is a strong character. She may start by grieving privately, not wanting to let her vulnerability show. As she is pregnant, she would feel an even greater sense of responsibility. She could start documenting stories about Percy for the baby, so that the child can know who their father was. And she would probably try to find a new purpose in life, centered around raising the baby in a way that Percy would have wanted.
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.
Annabeth could also be angry, not at Percy but at the situation or the forces that led to his death. She might vow revenge and start on a journey to find out who or what was responsible for Percy's sacrifice and make them pay. This could lead her into a whole new set of adventures and challenges as she tries to come to terms with her loss.
He could also become withdrawn and depressed. Percy and Annabeth have a very strong bond, and her death would leave a huge void in his life. He might isolate himself from his friends and family, lost in his grief and memories of her.
One possible reason could be her deep love for Percy. She might see his life as more valuable in the grand scheme of things, perhaps because of a prophecy or a mission that only he can complete. So, she chooses to sacrifice herself to ensure his survival.
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 possible scenario could be that Percy sacrifices himself to save Annabeth from a powerful and deadly monster. Maybe a huge and ancient sea creature that only Percy can hold off long enough for Annabeth to escape, but at the cost of his own life.
Well, perhaps it could be about a great battle where Percy sacrifices himself to save his friends or the world. Annabeth then cries because she has lost her beloved Percy. Maybe she blames herself for not being able to protect him, and the rest of the story could be about how she copes with this great loss, like she might try to carry on Percy's legacy or find a way to bring him back in some magical way.
On the other hand, she could try to honor Percy's sacrifice. Annabeth might focus on the reasons why Percy died for her and strive to fulfill any tasks or goals that he might have hoped she would achieve. She would carry on his legacy in a positive way, even though she is heartbroken.
She becomes very focused and single - minded. In a fanfic where Percy is poisoned, Annabeth quickly starts to research all possible antidotes. She interrogates other characters who might know something, and she doesn't rest until she has a lead. She also gets very emotional in private. She might cry when she thinks no one is looking because she's so afraid of losing Percy. But in front of others, she's strong and in control, leading the search for a solution to save him.
