The scales might give him new jutsu capabilities. For instance, he could learn to use the scales to create a sort of dragon - scale armor jutsu, where he can cover himself in a protective layer of scales that also has offensive capabilities, like shooting out sharp scale - like projectiles.
They could also affect his chakra. Maybe the dragon scales can store or filter chakra in a unique way. This could allow Naruto to have a larger chakra reserve or be able to use chakra more efficiently. For example, the scales could absorb ambient chakra and transfer it to Naruto, giving him an extra boost during battles.
It might be a gift from a powerful dragon in Naruto's world. In some fanfictions, there are hidden dragons that see potential in Naruto and bestow upon him the power of dragon scales, which could be a symbol of strength and protection.
The dragon scales might enhance Hiccup's physical abilities. For example, they could make him stronger, so he can better handle his weapons during battles. Also, they may improve his balance when he's riding Toothless, allowing for more daring maneuvers.
One idea could be a story where Naruto discovers his scale - like appearance after a battle in a mysterious dimension. He then has to figure out how to reverse it while also using his new form to his advantage against an emerging threat. For instance, the scales could be like a natural armor that he can enhance with his chakra.
I recommend the two novels,"The Divine Son of Destiny" and "I am a Professional Dragon Breeder", to you. Both novels involve the protagonist and the dragon-related plot. Although the plot is not exactly the same, they are both very worth reading ~ I hope you like my recommendations, muah ~😗
One possibility is that it could be related to some sort of new power or transformation. Maybe it's a result of an experiment gone wrong or a connection to a long - lost bloodline. For example, it could be a remnant of an ancient clan's ability that has been dormant in Naruto all this time.
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.

Well, it might enhance his physical strength a great deal. The dragon could teach him unique combat moves, like some dragon - style strikes. Also, his chakra control could improve as the dragon might have special techniques for that.
In some stories, the fox eyes might give Naruto a kind of hypnotic or intimidating power. Enemies might be momentarily stunned or less able to fight effectively when they look into his fox eyes. This could be a unique advantage in battles, allowing Naruto to gain the upper hand without having to use as much physical force.
