Another plot idea could be Percy having to deal with the moral implications of his blood - bending ability. He might struggle with whether it's right to control something so fundamental to life.
Perhaps Percy discovers that his blood - bending is connected to an ancient prophecy. He then has to go on a quest to figure out what it all means and how to control this powerful and somewhat dangerous ability.
A new healer character could be added. This character could be both intrigued and a bit wary of Percy's blood - bending ability and could try to help him understand it better.
Well, a great plot for a Percy Jackson Camp Half - Blood fanfic could be a time - travel story. Imagine some of the demigods being sent back in time to the era when the gods first created Camp Half - Blood. They could witness the founding events and also face the challenges that the first demigods had to endure. Or perhaps a story where the camp is invaded by a group of demigods from another pantheon, like the Norse demigods. This would lead to a lot of clashes and also potential alliances as they try to figure out who has the right to be at Camp Half - Blood. Also, a plot where a demigod discovers they have a connection to a long - lost prophecy that could change the fate of the camp forever.
Well, you could write a fanfic that focuses on the backstories of the characters in 'Blood of Olympus'. Maybe explore how Percy Jackson became the hero he is from a different perspective. Or create a plot where the gods interfere more directly in the demigods' quests in the fanfic. This could add more drama and tension as the demigods have to deal with the gods' complex personalities and motives on top of their existing challenges.
Perhaps a fanfic where Naruto's blood has some special connection to an ancient and powerful demon. The demon is slowly being awakened due to some dark magic related to Naruto's blood. Naruto has to face not only the threat of the demon but also the distrust from some in the village who think his blood is a danger. He must prove that he can control this situation and keep the village safe.
Another plot could focus on the origin stories of some of the side characters. For instance, the backstory of Yukina Himeragi. How did she become an attack mage? What kind of training did she go through? A fanfic could expand on this and also show how her past experiences influence her actions and relationships in the present story.
One idea could be exploring the backstories of the characters more deeply. Maybe delving into their childhoods and how those experiences shaped them into the people they are in the story. Another could be creating an alternate universe where the main characters have different occupations or abilities.
One plot idea could be Percy struggling to control this new and dangerous ability. He might accidentally harm someone he cares about while trying to learn how to use it properly, leading to a journey of self - discovery and redemption. Another could be Percy using his blood - bending to fight against an enemy that is immune to normal forms of attack.
One idea could be exploring the relationships between the demigods in more depth. For example, how Percy and Annabeth's relationship evolves after the events of 'Blood of Olympus'. Another could be creating a new adventure for the demigods that involves a forgotten prophecy. Maybe they have to travel to a new, unknown part of the mythological world to fulfill it.
Well, you could write a fanfiction where a minor character from the original 'Percy Jackson and the Blood of Olympus' gets their own story arc. Maybe a character who was always in the background but had a lot of potential. For instance, a demigod who discovers a new power related to the blood of Olympus that was previously unknown. They could then go on a journey to master this power and in the process, uncover secrets about the Olympians that were long forgotten.
A possible plot for an Atreus and Percy fanfic could be centered around a prophecy. The prophecy states that only the combined strength of a Norse and a Greek hero can stop an ancient evil from awakening. Atreus and Percy are brought together by this prophecy. At first, they are skeptical of each other because of their different backgrounds and ways of doing things. However, as they start to face the challenges related to the prophecy, such as deciphering ancient texts and fighting off minions of the evil, they gradually learn to trust and rely on each other. In the end, they succeed in preventing the evil from rising, and their friendship becomes a legend in both their worlds.
