Who are the main characters in 'Harry Potter heir of Arthur Pendragon' fanfiction?

There could be other characters from the original Harry Potter series who play important roles. For example, Hermione might be there to help Harry research and understand his Pendragon heritage. Ron could also be by his side, providing support and comic relief in the face of all the new and strange things that come with this discovery.

In some fanfictions, the heir of Arthur Pendragon could have a special connection to the magical creatures in the Harry Potter universe. Since Arthur was a great king, the heir might inherit his ability to communicate or form bonds with these creatures. This connection could be crucial in solving various mysteries in the wizarding world, like finding a hidden place where a powerful dark magic object is hidden. They could use the help of these creatures to outwit the villains who are also after the same object.

Saber from Fate/Stay Night would be an obvious choice. Since she is also related to the Arthurian legend, there could be a lot of interesting interactions between them. They could compare their experiences as king, or even fight side by side against a common enemy.

One interesting plotline could be the discovery of the connection between being the heir of Pendragon and Harry's existing powers in the wizarding world. Maybe it gives him new abilities or a different perspective on magic.

Obviously, Harry Potter would be one of the main characters. Since it's about him being the heir of Windsor, his character would be central to the story. Hermione and Ron would likely also be important characters as they are Harry's closest friends. There might also be new characters introduced who are related to the Windsor side of the story, perhaps some sort of magical relatives or advisors from the Windsor heritage in the wizarding world.

Obviously, Harry Potter is a main character as the heir of Excalibur. Hermione Granger would also likely be involved. She is always by Harry's side in the original series, helping him with research and providing intelligent solutions. So in this fanfiction, she might be the one to help Harry figure out the implications of being the heir.

Hermione and Ron could also be main characters. They are Harry's best friends in the original series and it's likely they would be involved in the story. Hermione with her vast knowledge of magic could help research about the Anubis heritage, while Ron could provide support and his unique brand of humor. Their presence would add familiarity and also a sense of friendship and teamwork to the fanfiction.

In some versions, there could be a love interest for the heir of God. This character could add another layer of complexity to the story, as the heir has to balance their relationship with their quest for knowledge about their identity and the use of their powers.

I'm sorry, without actually reading it, it's hard to say for sure. But it might include characters related to the Black family like Sirius Black or Narcissa Malfoy, and of course, the new 'black heir' character who would be central to the story.

In this fanfiction, Harry Potter is probably the central figure as it seems related to his new identity as the Heir of Death. However, other characters like Dumbledore could play significant roles. Dumbledore might be guiding Harry through this new discovery, or perhaps he's been hiding some secrets about the Heir of Death all along. Additionally, we may see characters from the dark side, like Voldemort or his followers, being involved in the story, either trying to stop the heir or use their power for evil.
