Percy could be one. He might flirt with her in a more playful, inside - joke kind of way. Like he'll make references to their shared adventures and say something like 'You know, you were really cute when you were fighting that monster back there, Annabeth. And you're even cuter now.' It's a light - hearted and affectionate form of flirting that's based on their deep bond.
Percy might be one. They have a close relationship, and in some fanfictions, he could be more forward with his feelings through flirting.
Percy would probably be an important character. He's Annabeth's close friend and love interest. His reaction to Annabeth getting her period could be interesting, like he tries to be supportive but is a bit clumsy at first.
Maybe an unexpected character like a wise centaur from the forest near the camp. They are known for their wisdom and strength in the Percy Jackson universe, and might step in to help Annabeth when they see her in trouble.
Well, it depends on who is flirting with her in the fanfiction. If it's someone she doesn't like, she'll probably be dismissive and give cold responses. However, if it's someone she has a bit of an interest in, she could be coy and a bit shy while still maintaining her confident facade.
Maybe an antagonist who wants to disrupt the group dynamic. If Annabeth is a key part of a group, punching her could cause chaos and confusion among her friends. It could also be someone who has been influenced by dark magic or some sort of mind - control in the fanfiction. This would make them act against their normal nature and punch Annabeth without really having a personal grudge.
Her family could be a great help. If they are aware of the situation, they can step in. Maybe her parents can talk to the school authorities or even directly to the bullies' parents. Family support is always crucial in such situations.
There's a chance it could be a new character introduced in the fanfiction. Maybe someone who has a mysterious past and enters Annabeth's life briefly but leaves a big impact, resulting in her pregnancy.
Maybe it's a human who has somehow discovered the world of demigods and is afraid of their existence. They shoot Annabeth out of fear and misunderstanding. Another option is that it's a rogue demigod who has gone bad and is working against their own kind. This character could have a personal grudge against Annabeth specifically, perhaps because of her intelligence and leadership skills which they envy.
It could be an enemy from the underworld. Maybe a powerful demon or a vengeful spirit that has a grudge against her. They might use their dark powers to harm her, like sending a bolt of dark energy her way.
Her close friends would most likely be involved. Percy, for sure. He would probably be worried about her and try to sober her up. Grover might also be there, trying to use his nature - related powers to find some herbs or something that could help her feel better.
