One of the main abilities is the transformation aspect. The gold dust can transform into different shapes and forms at the will of the user. It could turn into a golden armor to protect the user in battle, or into a net to capture enemies. Another ability is the density control. The user can make the gold dust extremely dense, like a solid gold boulder for a powerful attack, or make it very thin and spread out, like a golden mist to confuse opponents. In addition, in some fanfictions, the gold dust bloodline has a connection to the earth element, allowing the user to sense underground movements or even manipulate the earth in a limited way using the gold dust.
One popular 'Naruto Gold Dust Bloodline' fanfiction is 'The Golden Shinobi'.

In some fanfictions, Naruto might obtain the ability to control gold dust through a special encounter. Maybe he meets an ancient spirit or a powerful ninja who imparts this unique skill to him.
One potential application is in offensive combat. Naruto could shape the gold dust into sharp projectiles and launch them at his foes, like shurikens but made of gold. Also, he could use the gold dust to immobilize opponents by binding them with it, as it can be manipulated to his will. In the fanfiction, this would make him a more versatile fighter, able to adapt to different battle situations with this new ability.
In a fanfiction, the Dust Release Bloodline could be combined with other elements. For example, if the character also has some wind - based abilities, they could use the Dust Release in conjunction with the wind to create powerful dust storms that can blind and disorient enemies. They could also use it to create dust clones that are more durable than normal clones, as they are made of solidified dust particles.
A fanfiction could focus on a character who has the Dust Release Bloodline but is from a different village than the original user in Naruto. This character could be ostracized because of the power, seen as a threat. The story could be about how they prove themselves to their village and gain acceptance. For example, they use their unique ability to save the village from a powerful enemy attack.
