A possible plot is that Harry, being the son of Hermes, is hunted by dark forces who fear his potential. They think that his connection to Hermes gives him an edge in fighting against them. So, Harry has to constantly be on the run, while also trying to figure out how to use his Hermes - given powers to his advantage. He might have to learn how to use stealth and misdirection, which are traits associated with Hermes, to outwit his pursuers.
There might be. Fanfiction allows for a great deal of creativity and crossovers. Since the Harry Potter series has a huge fan base, it's possible that someone has written a story where Harry is the son of Hermes. This could lead to a whole new set of adventures and relationships for Harry. For instance, how would his relationship with Dumbledore be different? Or how would his skills in magic be affected by his new 'parentage'? It could also bring in elements of the Greek magical world if the writer decided to expand on the idea further.
Well, the plot could start with Harry always feeling a strange connection to things related to Hermes, like speed and trickery. As he grows older, he finds out he's Hermes' son. This revelation makes him question his place in the wizarding world. He then embarks on a journey to learn more about his new heritage. Along the way, he might meet Greek mythological creatures in the wizarding world. And he could use his new - found knowledge of Hermes' powers, like the ability to travel between different realms quickly, to fight against Voldemort and his dark forces in a more strategic way.
One interesting plot could be Harry discovering new and unique magical abilities that are not part of the original series. For example, he might be able to communicate with magical creatures in a more profound way. Another plot could involve Harry having a different family background that changes his relationships with other characters. Maybe he has a long - lost relative who is a powerful wizard from a far - off land, and this relative comes to Hogwarts to teach him some ancient magic. A third plot could be Harry being involved in a time - travel adventure within the wizarding world, where he has to fix some past mistakes that are affecting the present state of magic.
Well, one interesting plot could be Harry's struggle with his new identity as the son of Fenrir. He might have to deal with the stigma associated with Fenrir being a werewolf. Another plot could involve his relationships with other characters changing. For example, some friends might be afraid of him, while he tries to prove he's not like his father.
Perhaps a plot where Harry, as the son of Malfoy, discovers a hidden prophecy that links him to the downfall of Voldemort in a completely different way than in the original series. This could involve him using his knowledge of the Malfoy family secrets and connections to gain an advantage over the Dark Lord.
Well, in some plots, Harry might have special powers related to the moon. Maybe he can communicate with lunar spirits or use moonlight for magic in ways not seen in the original books. For example, he could use the moon's energy to enhance his Patronus charm, making it even more powerful against Dementors.
One possible plot is that Harry, as the son of Nyx, has to face off against a new enemy that is specifically targeting him because of his connection to Nyx. This enemy could be an ancient being that has a vendetta against Nyx and sees Harry as a way to get revenge. Along the way, Harry would have to learn more about his mother's (Nyx) powers and how to use them effectively, all while still dealing with the normal Hogwarts stuff like classes and friendships.
Well, in some of these fanfictions, there could be a plot where Harry discovers new magical abilities passed down from this 'G' figure. Maybe he can control a unique type of magic that no one else in the wizarding world has ever seen. This new ability might put him in a position where he has to face new enemies or challenges.
In some fanfictions, there could be a plot where Harry, as the son of Hestia, has to face opposition from traditional wizarding families who don't accept this new 'parentage'. This would lead to him having to prove himself not only as a powerful wizard but also as a worthy heir to Hestia's legacy. He might have to use his wits and newfound powers to overcome these prejudices.
Obviously, Harry Potter himself is a main character. Since it's about him being the son of Hermes. Hermione Granger and Ron Weasley are likely to be main characters as well. They are Harry's best friends in the original series and would surely play important roles in this fanfiction too. Maybe there are also new characters introduced, like descendants of other Greek gods who interact with Harry in the wizarding world.
