Naruto himself is often a popular character in these fanfictions. Writers like to explore how his already powerful abilities would be enhanced with a cosmic bloodline. Sasuke is also popular as his Sharingan could potentially be linked to some sort of cosmic power. Another popular character might be Kakashi, as his unique abilities and mysterious past could be further developed with a cosmic bloodline aspect.
One interesting idea could be the combination of different cosmic powers with the traditional Naruto bloodlines. For example, a character with the Uchiha bloodline might gain the ability to manipulate cosmic energy, enhancing their Sharingan abilities in unexpected ways. Another idea could be the origin of these cosmic bloodlines, perhaps they are remnants of an ancient alien race that once visited the Naruto world.
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.
In Naruto fanfiction, the concept of a bacteria bloodline can be really interesting. It could potentially give the character unique abilities. For example, they might be able to control bacteria for various purposes like healing or creating poisons. Some fanfictions may explore how a character with this bloodline is treated in the ninja world, whether they are feared or revered.
The Naruto creation bloodline fanfiction often explores the potential of genetic combinations. Some fanfictions might create a bloodline that has the power of both the Uchiha's Sharingan and the Hyuga's Byakugan. This could lead to a super powerful character with enhanced vision abilities and the potential to unlock new jutsus.
In fanfiction, a fem Naruto with a unique bloodline can open up many interesting storylines. For example, her bloodline could give her enhanced sensory abilities, allowing her to detect enemies from afar more easily. It might also be related to some special jutsu that only she can perform, like a new type of elemental manipulation.
The Ranton bloodline in Naruto fanfiction can bring really cool and unique abilities. It might include things like controlling water-based attacks in a special way.
