Who are the main characters in 'Game of Thrones Gravewalker' fanfiction?

Well, the idea of a Gravewalker in Game of Thrones fanfiction can bring in the concept of a different form of magic. It's not like the regular fire - based or blood - based magic we see in the show. This new form of magic related to the dead could potentially have a connection to the White Walkers in some fanfictions. Maybe the Gravewalker has the ability to control or at least influence the White Walkers in a way. It could also be that the Gravewalker is a key to unlocking some ancient secrets about the First Men and their relationship with death and the afterlife.

Since I don't know the exact 'naruto gravewalker fanfiction', it's hard to say for sure. But it could feature Naruto himself as a main character, perhaps he discovers the world of the gravewalker. Or it could be an original character created for this fanfiction who is the central 'gravewalker' figure.

The Gravewalker is obviously a main character. They are the central figure around which the story revolves. Then there could be Harry Potter himself. Since it's a fanfiction set in the Harry Potter universe, Harry might interact with the Gravewalker, either as an ally or an adversary. Hermione and Ron could also be involved, depending on how the story is crafted.

Often, there could be a young and idealistic character who leads the uprising. Maybe a bastard son or daughter of a noble house who has seen the injustice in the system. Another could be a former slave who has escaped and now wants to free all his fellow slaves. And there might be a maester who has been exiled from the Citadel for his radical ideas and joins the uprising.

A young and clever maid in the service of one of the noble families in Queensgate could be a main character. She might be privy to a lot of secrets and use her wits to navigate the dangerous political waters. Maybe she overhears a plot against her master and has to decide what to do about it.

It could be a new character created specifically for the fanfiction. This character might be an outcast from a noble house who receives the call and is thrust into the center of the power struggles in Westeros.

In some fanfictions, Jon Snow could be a central figure when combined with the angel elements. Imagine an angel bestowing upon Jon some new powers or knowledge that helps him in his fight against the White Walkers. And there could be a female angel character who has a special bond with Jon, guiding him not just in his battles but also in his personal growth as a leader.

Sure. Fanfiction writers often like to cross - over different universes. In a 'Tony Stark Game of Thrones' fanfic, Stark may find himself in Westeros and use his Iron Man suit to his advantage. He could end up being a key player in the power struggles, for example, helping a particular house with his technology against the White Walkers. His presence would definitely shake up the political and military dynamics of the Seven Kingdoms.

Daenerys could be a main character. She has leadership skills and her dragons could be a huge asset in a war - like scenario inspired by WWI. Another could be Jon Snow. His experience in leading the Night's Watch and fighting the White Walkers could translate into him being a key figure in this fanfiction's battles. Tyrion Lannister would also be a likely main character. His intelligence and ability to strategize would be very useful in a complex situation like a WWI - style conflict in Westeros.

Myrcella is a young and somewhat naive girl at the start. She has grown up in a different environment compared to Trystane. Trystane, on the other hand, is more in tune with the Dornish ways. Their differences and similarities are what make their interactions in the fanfiction so interesting. They both have to navigate the complex political situation in Westeros that affects their relationship.
