In a 'dark blood Naruto fanfic', the dark blood could give the wielder the ability to see the darkest secrets of others. Naruto, with his new power, uncovers a conspiracy within the ninja world that is far more dangerous than anyone thought. He has to use this power, which is feared by many, to save the world while also dealing with those who want to stop him because of his 'dark' ability.
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 involve Naruto having to deal with a hidden power within the Blood Prison that is starting to corrupt the inmates and guards alike. He has to find the source and stop it. For example, there could be an ancient curse that was placed on the prison long ago and is now awakening. Naruto, with his strong will, tries to resist the curse's influence while also finding a way to break it for everyone else.
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.
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 idea could be exploring the dark side of Naruto himself. For example, what if he was corrupted by the power of the Nine - Tails and turned against the Hidden Leaf. He might use his new - found, malevolent power to take over the village, creating a dark regime. Another idea could be delving into the backstories of the Akatsuki members in a more detailed and darker way. Maybe exploring how they were pushed to the dark side, and writing a fanfic from their perspective during their most desperate and evil moments.
In 'naruto dark chakra fanfic', perhaps an interesting aspect is the unique jutsu Naruto could develop with the dark chakra. It could be a new form of Rasengan that has a darker, more menacing look and stronger power.
Perhaps they are living in a parallel universe where everything is dark and gloomy. Dark Naruto and Dark Kushina could be trying to find a way to break through to the normal universe. They might encounter strange versions of their friends and foes, and have to battle their own inner demons along the way. For example, Dark Naruto might struggle with the darker aspects of the Nine - Tails' power that he has fully embraced in this universe.
One idea could be exploring the backstory of the main character in the 'dark paradise'. Maybe they had a difficult childhood that led them to the dark situation they are in now.
One idea could be a character who discovers they have blood - bending abilities in the Naruto universe and has to hide it from their village at first. Maybe they are from a non - water - based village and fear being ostracized. Another plot could involve a blood - bender using their power to heal instead of harm, which goes against the traditional view of blood - bending in other fictional universes. A third idea might be a blood - bender who gets caught in the middle of a war between two great ninja powers and has to decide which side to use their power for.
