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.
Yes, there are quite a few. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Naruto has a dragon bloodline' and you'll find a variety of stories. Some might focus on how Naruto discovers his dragon bloodline, while others could explore the new powers it gives him and how it changes his relationships with other characters in the Naruto universe.
Some of his friends might be in awe of him. They could see him as even more of a hero or someone to look up to. For example, Konohamaru would probably be even more excited to train with Naruto and learn from him. However, some friends might also be a bit jealous of his new powers. Sakura might initially be a bit wary, but she would also be concerned about how Naruto is handling this new power.
He becomes more confident. With the new powers from the dragon bloodline, he feels like he can take on stronger opponents. For example, he might not be as hesitant in battles against tough foes like he used to be.
The dragon bloodline often makes Naruto more powerful and confident. He realizes he has unique abilities that set him apart. This newfound power can change his attitude towards challenges, making him more fearless.
A possible plot development is that the dragon bloodline in Naruto causes other ninja clans to be either jealous or fearful. This leads to political intrigue where some clans try to either steal his bloodline or eliminate him. Naruto then has to navigate through this web of deception and danger while also trying to master his new powers. He might even form unexpected alliances with clans who see the potential of his dragon bloodline for the greater good.
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 these fanfics, a typical plot point is the transformation aspect. Naruto may transform into a more dragon - like form when using his full power. This transformation not only gives him more physical strength but also new jutsu - like abilities. Another common plot point is the training arc. He has to learn how to control his dragon bloodline powers, which is often difficult as they are so powerful. Sometimes, his dragon bloodline also attracts the attention of other powerful entities in the Naruto world, either those who want to use him or those who see him as a threat, which leads to various conflicts and plot developments.
On the other hand, the Dragon Bloodline could also create some jealousy or tension. If the character starts getting a lot of attention because of their unique bloodline, Anko might feel a bit left out. However, as the story progresses, they could work through these feelings and develop a stronger, more equal relationship.
