A great plot idea could be that the Dragon Blade is a cursed object that starts causing chaos in the ninja world. Naruto, being the hero he is, tries to find a way to break the curse. Along the way, he teams up with some unexpected allies, maybe some old enemies who also realize the danger of the blade. As they explore the mystery of the blade, they find that it was created by an ancient civilization with a purpose that has been long forgotten. Naruto has to use his wits and his ninja skills to figure out how to stop the blade's destruction before it's too late.
Well, perhaps in 'Naruto Dragon Blade Chronicles Fanfic', there's a plot where the Dragon Blade is actually a key to an ancient and powerful ninja technique. Naruto and his friends have to protect the blade from falling into the wrong hands. They might encounter a group of rogue ninjas who are after the blade for their own evil purposes. And as they fight to keep it safe, Naruto discovers a connection between the blade and his own family's past, which gives him new motivation and strength.
One interesting plot idea could be the discovery of a hidden power within the Dragon Blade that only Naruto can unlock. This power could be linked to an ancient prophecy. Another could be Naruto teaming up with new characters from the Dragon Blade lore to face a common enemy that threatens both the Naruto world and the world related to the Dragon Blade.
One idea could be a 'what if' scenario where Naruto has a different elemental affinity from the start. For example, if he was born with a natural affinity for water instead of wind.
One idea could be Naruto going on a secret mission in a hidden land not yet explored in the original series. Maybe he discovers a new type of chakra there.
One idea could be a story where the character with blade arms has to protect a hidden village from a new and powerful enemy. Maybe they use their unique blade arms to fend off attacks and discover a secret about their origin in the process.
One interesting plot idea could be the main character, perhaps a new ninja in the Naruto world, discovers the power of the dragon sage mode through a hidden ancient scroll. This new power sets them on a journey to master it, facing challenges from both traditional ninja clans who are suspicious of this new power and dark forces that want to steal it for their own evil purposes.
One idea could be a crossover where Naruto characters get access to special blades with unique powers. For example, Naruto could get a blade that amplifies his chakra and allows him to perform new jutsu. Another could be a story where a hidden blade is discovered in the Naruto world that has the power to either save or destroy it, and the characters have to fight over its possession.
One idea could be exploring a different origin for the dragons. Maybe they were created by an ancient civilization for a specific purpose that has been lost over time.
You could write a fanfiction where there is a conflict between different groups of keepers. Some might believe in a more traditional way of keeping dragons, while others want to introduce new methods. This could lead to a power struggle and even put the dragons in danger. It would allow for exploring different ideologies within the world of 'Dragon Keeper Chronicles' and how they affect the overall story.
Another plot could revolve around Nick's relationships. For example, a deep exploration of his friendship with a particular character. How they met, what challenges they faced together, and how their bond grew over time. This could add a lot of emotional depth to the fanfic.
One idea could be exploring the origin of the Totsuka Blade in the Naruto universe more deeply. Maybe it was created by an ancient clan with a special connection to the afterlife. Another idea is to have a character other than Itachi use the blade in a completely different way, like a young ninja who discovers its power accidentally.
