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.
In Greek mythology, Hera was the queen of the gods. Her origin story is often linked to Cronus and Rhea. She was their daughter. Cronus, fearing that his children would overthrow him, swallowed his offspring. However, Rhea managed to save Zeus by tricking Cronus, and later Zeus rescued his siblings, including Hera. Eventually, Zeus married Hera, and she became the goddess of marriage and family, ruling over Olympus beside Zeus.
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.
The relationship can start with mutual distrust. Percy has seen Hera's manipulative side before, and Hera might not fully trust Percy at first. But then, they could be forced to work together on a task. For example, saving a group of demigods from a powerful enemy. As they face challenges side by side, they begin to respect each other's abilities. Percy realizes that Hera has her reasons for her actions, and Hera sees Percy's courage and loyalty.
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.
In the Star Wars universe, such a scenario would be highly complex and out of the ordinary. Ahsoka has a deep connection with the Jedi teachings, and Darth Vader is on the dark side. If she were pregnant, it would likely be a situation full of moral and ethical dilemmas. She might struggle with protecting the child from the Sith and Vader's influence, and also deal with how the Jedi Order would react, as they have strict rules about relationships and attachments.
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 plot could revolve around Naruto being sent to the Naruto - like world as a sort of mission by Hera. Since she holds the Kybii, she entrusts Naruto with a part of its power. Naruto then has to use this power to protect the world from a new and powerful threat. However, the power of the Kybii attracts the wrong kind of attention, and Naruto has to constantly fight off enemies who want to take it from him. At the same time, he has to keep his identity as Hera's son a secret, or else it could cause chaos in the world, both among the ninjas and in the divine realm that is somehow connected to his world.
