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.
The entire crew of Gold Roger could potentially be allies in a way. They are a tight - knit group. The OC could bond with different members over shared interests. For instance, the cook might share food with the OC and in return, the OC could help him find rare ingredients during their travels. This sense of community within the crew can be a strong support for the OC.
In the fanfiction, Harry might find allies among the ghosts in Hogwarts. Since he is the son of Hades, he could have a special connection with them. They could provide him with information and support. Another potential group of allies could be the outcasts in the wizarding world. People who have been shunned or misunderstood might be drawn to Harry because they see him as a fellow outcast due to his new identity. And there's also a possibility that some of the more rebellious students at Hogwarts, who are not afraid to go against the norm, would become his allies and help him face the challenges that come with being the son of Hades.
Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. There, you might find different interpretations of this concept. Some stories might focus on how Harry's love for gold could be related to his adventures, perhaps he discovers a hidden treasure and his relationship with it evolves in an interesting way.
I'm quite sure Harry Potter doesn't sell gold fanfic. The Harry Potter series is a fictional story mainly about magic, friendship, and the battle between good and evil. Fanfic related to it is often the creative work of fans, not something that the original concept would sell as 'gold fanfic'.
Hermione would definitely be one of his allies. She is smart and would be able to help him research about his new identity and how to control his powers. For example, she could find ancient texts in the Hogwarts library that relate to both the wizarding world and the Greek gods.
His friends from Hogwarts could still be his allies. Hermione would use her intelligence to help him understand his new situation. Ron would be there for moral support. Additionally, any friends or allies that Rias has in her world could also become Harry's allies. They might be magical creatures or other powerful mages.
Hermione could be a potential partner. They have a long - standing friendship and have been through a lot together. Their shared intellectual pursuits and understanding of the wizarding world could make them a great couple who decide to have a baby together.
Dumbledore could be a savior in this fanfiction. He has the power and the wisdom to step in and help Harry. He might have been waiting for the right moment to remove Harry from the Dursleys' influence. Also, there could be a new character, like an old and powerful wizard who has been in hiding but senses Harry's distress and comes to his aid. This wizard could have some unique magical abilities that can protect Harry and help him grow into a powerful wizard himself.
Hermione would definitely be an ally. She's smart and would be able to help Harry research about his 'son of Mars' heritage, finding ancient spells or texts that could explain it further.
