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 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.
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.
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.
Well, Naruto is a must - have main character. He might be the one who unlocks the dragon slayer bloodline's true potential. Hinata could be another main character, her Byakugan ability might interact in interesting ways with the dragon slayer powers. There could also be a mysterious character who is an elder of the dragon slayer bloodline clan. This character could hold the key to understanding the bloodline's history and secrets, and thus be an important main character in the fanfiction.
One good example could be 'Naruto: Dragon's Legacy'. In this fanfiction, the dragon bloodline gives Naruto unique powers that attract a harem of various characters. The story often has exciting battles where Naruto uses his new abilities. Another is 'Dragon - Blooded Naruto in the Harem World'. It focuses on how Naruto's dragon bloodline affects his relationships within the harem, creating a lot of interesting character dynamics.
One interesting concept could be the combination of Naruto's ninja abilities with the dragon slayer powers. For example, Naruto might use his shadow clones in unique ways when fighting alongside dragon slayer - like attacks. Another concept could be the origin of the dragon slayer bloodline in the Naruto universe. It could be tied to some ancient and forgotten clan. Also, the way the characters interact with dragons in this fanfiction can be really cool, like forming alliances or having epic battles against them.
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.
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.
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.
