It changes the story in many ways. For one, Naruto's fighting style would be different. Instead of relying solely on his shadow clones and Rasengan, he would incorporate genjutsu. His battles would become more strategic as he uses genjutsu to deceive his opponents before attacking. For example, he could make an enemy think there are multiple Narutos attacking from different directions when it's just a genjutsu.
One interesting concept could be a new bloodline that has the power to reverse genjutsu. Instead of being trapped in an illusion, those with this bloodline can turn the tables on the caster. For example, they can make the genjutsu caster experience their own illusion in a more powerful and dangerous form.
One way is by having a character with a bloodline that can use genjutsu without the need for hand signs. This would set them apart from most ninjas in the Naruto universe. They could cast genjutsu instantaneously, catching their opponents off - guard. It also shows their natural affinity for genjutsu and implies a very powerful bloodline.
In some fanfictions, Naruto's genjutsu bloodline might be a result of some hidden experiment. This could lead to a lot of internal conflict in him as he tries to understand how he got this power. He might struggle with the idea that he was experimented on, but at the same time, he uses the newfound genjutsu abilities to protect his friends and the village. He could develop genjutsu that can manipulate the emotions of his opponents, making them feel fear or doubt.
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 fanfictions, one of the bloodline limits could be something like a super-enhanced Sharingan-like ability. Another might be a power related to controlling natural elements in a unique way, for example, a more powerful form of water control. And perhaps a bloodline limit that gives Naruto the ability to instantly teleport short distances. However, different fanfictions can have very different interpretations of these six bloodline limits.
In the fanfiction, Naruto might use his chakra control skills to create a genjutsu that alters the perception of those who see him. He could project an image of his unscarred self over his actual body. For example, he focuses his chakra on the area around his scars and manipulates the light and the way it reflects off his skin in the eyes of others, making the scars seem to disappear.
In some fanfictions, Naruto becomes a master of genjutsu through intense training. He might learn from a new mentor or discover ancient scrolls that teach him advanced genjutsu techniques. This often makes him a more well - rounded ninja, able to deceive opponents in combat as well as use his regular combat skills.
One great fanfiction is 'The Genjutsu Master's Ascent'. It follows a character who has a unique take on genjutsu, combining different ninja techniques with it in creative ways. The story is well - paced and the battles are exciting.
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.
