One idea could be a story where a new character discovers a long - lost mind - related bloodline ability that allows them to communicate with the spirits of past Hokages in their minds. Another could be a plot where a villain uses a mind bloodline to manipulate the memories of the villagers to turn them against Naruto.
First, you should brainstorm ideas about the mind bloodline. Decide what unique abilities it has. Then, create a main character who either has this bloodline or is affected by it. Next, think of a conflict. Maybe it's a battle against others who want to use the bloodline for evil.
One popular plot could be a character with a new bloodline that allows mind control trying to take over the Hidden Leaf Village. They might start by targeting key ninjas like Kakashi or Shikamaru. Another plot could involve a villain using the mind control bloodline to turn the ninja clans against each other. And there could also be a plot where a young ninja discovers they have this bloodline and has to struggle with the power and the temptation to use it for wrong reasons.
In Naruto fanfiction, the mind control bloodline can have a huge impact on character relationships. If a ninja uses the power to make another ninja do their bidding, it can lead to mistrust among their comrades. They might start to question who they can really trust. Moreover, if a character is mind - controlled into betraying their clan, they will face a lot of difficulty in being accepted back. Their family and friends will have to grapple with the fact that the betrayal wasn't entirely their fault, but still, there will be a sense of unease and a need to rebuild the relationship.
Sasuke could be an interesting choice. He already has a complex personality and adding the mind control bloodline to his abilities would make his character even more multi - faceted. He could use it to further his revenge plans or, in a different turn, to protect his friends and the village.
Well, in such a fanfic, the origin of the mind control bloodline can be a really fascinating aspect. It could be an ancient power that was lost and rediscovered. This could lead to a whole story arc about the search for the knowledge to master this power. And perhaps it has some connection to an old clan that was once feared for their mind - controlling abilities.
There are also fanfictions where a bloodline is created through some sort of experimental jutsu. For example, a bloodline that allows the user to transform into different elements at will. This would give the character an edge in combat as they could adapt to any situation by changing their form.
The knight bloodline could be integrated as a foreign power that was brought to the Naruto world long ago. Maybe a group of warriors from another dimension with the knight bloodline came and settled, and over time their bloodline got diluted but still resurfaces in certain individuals.
He might use some special jutsu or seals. For example, he could use a sealing technique to suppress the signs of his bloodline. This way, others wouldn't be able to detect it through normal means like sensing chakra.
It could also be part of a strategic move. By hiding his bloodline, he can surprise his opponents in battle. They would underestimate him based on not knowing about his true powers, and then he could turn the tables on them when the time is right. This gives him an edge in combat situations.
