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.
In some fanfics, Naruto absorbs the bloodline through a special jutsu. For example, he might find an ancient scroll that contains a jutsu allowing him to transfer and absorb the genetic traits related to a bloodline.
In these fanfictions, a common unique feature of the Hozuki bloodline is the ability to turn into a liquid - like form. This allows the characters with this bloodline to pass through small spaces, avoid attacks, and even trap enemies within their liquid bodies.
One unique ability could be the power to manipulate bones at a molecular level. This would allow the character to reshape their bones into various forms, like sharp weapons or protective shields. Another ability might be the capacity to sense vibrations through the bones, giving them an edge in combat by detecting enemy movements even through solid objects.
It could completely change the dynamics of his powers and his journey. Maybe he'd have an easier time mastering jutsu or face new challenges related to his unique bloodline.
Well, one implication could be enhanced physical abilities. Dragons are often seen as strong and powerful creatures in many mythologies. So Naruto might have greater strength, speed, and endurance. He could also have some sort of elemental control related to dragons, like breathing fire or manipulating wind in a more dragon - like way. Maybe he could even fly in some forms, as dragons are known for their flight ability.
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.
In Naruto fanfiction, the Sharingan is often explored in unique ways. For example, some fanfictions might expand on its ability to not only copy jutsu but also to predict an opponent's moves on a whole new level. Another interesting bloodline concept could be the Uzumaki's massive chakra reserves, and fanfictions may play with how this could be used in different scenarios, like creating entirely new jutsu.
