One interesting plot could be a character with an invisible bloodline being initially underestimated. For example, they could be in a ninja academy and seem like an ordinary student. But during a dangerous mission, their invisible bloodline power kicks in, allowing them to become invisible at will and surprise the enemies. This power could also have limitations, like they can only be invisible for a short time before needing to rest.
The character with an invisible bloodline might become an outcast at first. People might be afraid of their unknown power. However, as the story progresses, they could prove themselves and become a symbol of hope. Their unique bloodline could attract both allies and enemies. Allies would see their potential, while enemies would target them to prevent their growth, thus shaping their role as a central figure in the fanfiction's conflict.
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.
Another possibility is that he gets help from a powerful ally. This ally could be a sage or a spirit who bestows upon Naruto the power of invisibility. They might see Naruto's potential and the importance of his mission and decide to give him this special ability. It could also be a side - effect of a powerful transformation he undergoes, like a new sage mode or some other super - powered form that has the added benefit of making him invisible.
In some fanfictions, Naruto might turn invisible through a special jutsu he discovers or is taught. It could be a new form of ninjutsu that manipulates light and reflection to make his body unseen, much like the way some real - world concepts of invisibility work by bending light around an object.
The 'naruto invisible lemon fanfiction' might have some really distinct features. The 'invisible' aspect could refer to things like unseen powers, hidden identities, or covert missions within the Naruto universe. As for the 'lemon', it could be a metaphor for something that adds a bit of zing or acidity to the story, like a difficult moral dilemma for the characters, or a relationship that has some sourness or complexity. It could also be that the story has a certain mystery or enigma that's not easily perceived, much like an invisible lemon.
Naruto could use his invisibility for stealthy missions more effectively. He could gather intelligence without being detected, which would give Konoha an edge in battles or political situations. However, it could also make him a target for those who know about his new ability and want to capture or study it for their own purposes.
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.
