It can create a lot of twists. For example, if a character with the shapeshifter bloodline is initially thought to be a weakling but then reveals their power, it can turn the whole plot around. They could infiltrate enemy groups by shapeshifting, which would be a great advantage for their side.
Well, in some Naruto shapeshifter bloodline fanfiction, the idea of a bloodline that enables the character to shapeshift into different elements is really cool. Imagine a character being able to transform into water to avoid attacks or into fire to launch surprise offensives. It gives a whole new dimension to combat and strategy in the Naruto world.
One interesting aspect could be the new abilities Naruto would have as a shapeshifter. He could use this power to deceive his enemies in ways he couldn't before. For example, he could transform into an enemy ninja to infiltrate their hideouts.
Perhaps a group of rogue ninjas who are threatened by Naruto's shapeshifting ability. They might see him as a threat to their plans and try to eliminate him. They could be led by a mastermind who is well - versed in countering shapeshifting techniques.
Well, a major theme is the struggle for acceptance. In these fanfictions, the immortal shapeshifter is often different from the normal inhabitants of the Naruto world. So, they have to deal with how others perceive them and try to find their place. Also, there's the theme of destiny. Given their immortality and shapeshifting ability, they might be seen as having a special role or destiny in the Naruto universe, which is often explored in these stories. Additionally, the theme of friendship and loyalty is common. They form relationships with Naruto characters and these relationships are tested due to their unique nature.
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.
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.
