One example could be a situation where Annabeth sees Percy getting a lot of attention from a new girl in their group. She might start acting cold towards Percy, which is a classic sign of jealousy in fanfiction. In such a story, the author might explore her insecurities about her relationship with Percy.
Well, perhaps Rachel has some unique talents or abilities that catch Percy's attention. In the fanfiction, this might make Annabeth feel insecure about her own relationship with Percy. For example, if Rachel can communicate with the gods in a way that Annabeth can't, and Percy is impressed by it, Annabeth could get jealous.
Another way it could end is that through the jealousy, Annabeth discovers new things about herself. She realizes that she has been taking Percy for granted in some ways. So, she works on herself and her relationship with Percy. Rachel may or may not still be in the picture, but Annabeth and Percy's bond becomes deeper and more understanding, with Annabeth no longer feeling jealous.
It could be new girls who come into the camp. They see Annabeth's position and all she has achieved, like her close friendship with Percy and her role as a leader, and they become jealous. Maybe some minor characters who have always been in the background and feel overshadowed by Annabeth.
One common scenario is when another girl shows interest in Percy. For example, if a new demigod arrives at Camp Half - Blood and she's constantly around Percy, Annabeth might get jealous. She could start acting cold towards Percy or be overly critical of the new girl. Another situation could be if Percy has to go on a quest with a female partner and they seem to be getting along really well. Annabeth might worry that Percy will develop feelings for this other girl.
Well, in many Percy - related fanfictions, if we consider Grover as Annabeth's friend, he might be jealous of Percy because Percy often gets more attention or seems to be more in the spotlight. Percy has a lot of heroic moments and is the son of Poseidon which gives him a certain status, and Grover might feel overshadowed at times.
One reason could be their different areas of expertise. Annabeth is highly skilled in architecture and battle strategies in the Percy Jackson world. Hermione, being a brilliant witch in the Harry Potter universe, might feel jealous if she perceives Annabeth as having more practical and hands - on skills. Another factor could be their relationships. If Annabeth has a really great relationship with someone Hermione admires or wishes to be closer to, it could stir up jealousy. For example, if they were in a shared universe and Annabeth was closer to Harry or Ron than Hermione was.
In this kind of fanfiction, often the jealous demigods might be jealous of Percy and Annabeth's relationship or their status as heroes. Maybe they're jealous of Percy's powers over water or Annabeth's strategic mind. This can lead to all sorts of conflicts, from petty rivalries to full - blown battles.
In many fanfictions, Annabeth might be jealous of Percy because of his popularity or his close relationships with other characters. It could also be due to his natural talent in certain areas that overshadows her own at times.
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.
