One common scenario is when there are challenges or competitions among the gods. Ares might see Percy as his 'prize' if he wins. For example, in a fan - created tournament where different gods compete for certain mortals or demi - gods, Ares could be extremely possessive of Percy if he manages to claim him in the competition.
In some fanfictions, there could be a situation where Percy has some sort of special power or connection that Ares wants to use for his own war - mongering purposes. So, Ares becomes possessive, trying to isolate Percy from others who might protect him and keep him under his own control so he can exploit that power or connection at will.
Another scenario could be when Percy stumbles upon a powerful artifact or knowledge that Ares wants. Ares might then try to possess Percy as a means to get to that valuable thing. He could keep Percy close, showing possessiveness, until he gets what he desires from Percy or the situation related to Percy.
One common scenario is when Percy is in danger during a battle with a powerful monster. Poseidon might send some kind of sea - based assistance, like a helpful sea creature to fight alongside Percy or create a protective barrier of water around him. Another could be when other gods or demigods try to harm Percy unjustly, and Poseidon intervenes in a more subtle way, perhaps by influencing the situation to keep Percy safe without directly showing his power.
One common scenario is when Percy is forced to go on yet another dangerous quest without much support from the gods. He might be angry and show his hatred at that moment. For instance, if he is sent to retrieve some powerful artifact with very little information and no real backup from the gods.
One way is through their actions. For instance, the Hunt might always be by Percy's side, not giving him much personal space. They could be very quick to defend Percy from any perceived threat, even if Percy doesn't think it's necessary.
One common scenario could be in the face of other students' bullying. Snape might subtly step in and stop the bullies without making it too obvious. For example, he could give the bullies extra assignments or detention, which would indirectly protect Hermione from their taunts.
Zeus is often one of the main gods showing possessiveness. He sees Percy as a powerful asset or a potential threat, so he wants to keep Percy in check. Poseidon, as Percy's father, also shows possessiveness in a different way. He wants to protect Percy but also use his powers for his own purposes sometimes.
In some fanfiction, Naruto might become disinterested in Sakura because of a change in his ninja career. For instance, if he is assigned to a long - term mission far away from the village where Sakura is. During this time, he meets new people and has new experiences that change his perspective. He could also start to value different qualities in a person. Maybe he used to like Sakura's determination, but now he realizes that there are other qualities like kindness and acceptance that are more important to him. And Sakura doesn't possess these new qualities he values, so he loses interest in her.
Well, it could affect the plot in various ways. The gods' possessiveness might mean that Percy has limited freedom. He may constantly be under the watchful eyes of the gods, which restricts his actions. Also, it could lead to power struggles among the gods themselves, with Percy caught in the middle. Maybe one god tries to protect Percy from the others' possessive actions, adding more twists to the story.
One possible scenario is when his parents accidentally harm one of his ghost friends while trying to hunt ghosts. Danny might get really angry and show his hatred towards them for being so reckless. Another scenario could be during a family dinner when they start talking about their latest ghost - hunting inventions and how they plan to use them to catch more ghosts. Danny, feeling threatened by this, could snap and show his dislike for them.
Since lemon fanfictions are inappropriate, I can't really discuss the common themes in them. But in general non - lemon Percy and Ares fanfictions might have themes like power struggle, as Ares is a god of war and Percy has his own powers. Another could be the clash of their personalities, with Percy's more heroic and selfless nature against Ares' more violent and self - centered one.
A theme that often comes up is the clash of ideologies. Percy, with his more modern and empathetic view, against Ares' traditional and often brutal view of war. Also, the theme of heroism is there. Percy is seen as a hero, and his battles with Ares can be seen as a test of his hero - status, with the fanfiction exploring different aspects of what it means to be a hero in that context.
