Another storyline could be that Hera is tricked into cheating on Zeus. A cunning deity or magical entity manipulates her emotions and makes her believe she is in love with someone else. As she gets involved with this new love interest, she realizes she has strayed from Zeus and then has to deal with the consequences of her actions.
It could be a mortal man. In Greek mythology, gods sometimes had affairs with mortals. Maybe a particularly handsome and charming mortal catches Hera's eye. He might be a great hero or a simple shepherd with a pure heart.
One interesting storyline could be Hera and Zeus having to work together to save Olympus from a new, powerful threat. In this scenario, Percy Jackson might get caught in the middle. Maybe the threat is a primordial being that has awakened and only the combined power of Hera's cunning and Zeus's strength can stop it.
Perhaps in a fanfiction, Zeus, in a fit of anger over Hera's interference in one of his mortal affairs, uses his power to ostracize Hera from the other gods for a time. This makes Hera feel isolated and hurt, and she has to find a way to regain her standing while also dealing with the betrayal of her husband. It could show her strength as she overcomes this difficult situation.
A possible storyline could be that Hera's pregnancy is a mystery. No one, not even she, knows who the father is. This could lead to a lot of speculation and gossip among the gods. Another idea is that the pregnancy is a sign of an impending doom or great change in the cosmos. The gods might be divided on whether to welcome this new life or try to prevent it.
Hera was Zeus' wife. Her main role was to be the queen of the gods. But in their relationship, she was often the one trying to keep Zeus in check due to his many affairs.
One possible reason could be that in the context of the fanfiction, Hera is tired of Zeus' constant infidelities. She might have reached a point where she just can't bear to deal with him anymore, so she chooses to ignore him as a form of self - protection.
The relationship changes in terms of emotional connection. Hera's ignoring Zeus might mean that the emotional bond that was there (even if it was a tumultuous one) is starting to break. This could have far - reaching consequences in the fanfiction world, like affecting the balance in the pantheon or causing other gods and goddesses to take sides depending on how they view Hera's actions towards Zeus.
Well, in some fanfictions, Itachi might seem to be cheating on Naruto in the sense that he's forming closer alliances with other characters for strategic purposes. For example, he could be getting involved with another ninja clan to gain information or resources for the greater good, but Naruto misinterprets his actions as being unfaithful in their friendship.
One possible storyline could be that Artemis is influenced by some dark magic that makes her act out of character and cheat on Percy. This could lead to a big conflict within the fanfiction world, with Percy feeling betrayed and his friends trying to figure out what happened to Artemis. Another idea might be that there's a misunderstanding. Maybe Artemis was framed or something made it seem like she was cheating when she really wasn't. This could create a lot of drama as Percy has to decide whether to believe her or not.
It could be that the writer wants to explore the darker side of human nature within the context of these characters. By having Annabeth cheat with Zeus, they can delve into themes like betrayal, jealousy, and the breakdown of relationships. Additionally, some might be doing it as a form of rebellion against the 'perfect' relationship that Annabeth and Percy seem to have in the original, wanting to add a bit of chaos and realism to the fictional world.
