Definitely the Avengers as a whole group or at least some of the key members. On Loki's children's side, if it's a more in - depth exploration, it could involve all of his known children. But if it's a simpler story, maybe just one of them like Jormungandr, the sea serpent. Jormungandr could bring a whole new element to the story, perhaps causing trouble in the oceans which would draw the attention of the Avengers, especially those with ties to the sea or aquatic environments.
The Avengers are a must - they are the heroes of the story. For Loki's side, his children who have their own distinct traits. If the story focuses on the more well - known children, then Fenrir, the giant wolf, would be a major character. He has great strength and could pose a real threat or an interesting ally. Also, Thor might have a special connection or conflict with him due to his relation to Loki.
The plot might involve Loki's children being in a situation where they need the Avengers' help. Since the Avengers are known for protecting the Earth and the universe, they could get involved. There could be a lot of character development as the Avengers learn about Loki's children and vice versa. It could also explore how the Avengers' values might clash with those of Loki's kids at first.
Obviously, the Avengers like Iron Man, Captain America, Thor etc. would be main characters. And Loki's children, whoever they are in the fanfiction's interpretation. Maybe there would be a new character created specifically for this story as well who becomes important in the interactions between the two groups.
I think it could be Star - Lord. He's often looking for an edge in any situation, and Loki could offer some unique opportunities. They could form a sort of uneasy alliance where they both try to use each other for their own goals. Star - Lord might see Loki as a valuable asset in terms of his magic and knowledge of other worlds, while Loki could use Star - Lord's leadership skills and connections within the Guardians. However, they would constantly be on guard against each other's double - crosses.
Loki and Thanos are the central figures. However, characters from Loki's family such as Thor could also be significant. Thor might notice the changes in Loki and try to rescue him from Thanos' control. Additionally, characters like Heimdall, who has the ability to see across the realms, could be involved in detecting Loki's unusual behavior and Thanos' influence.
Well, in such a fanfiction, there could be intense battles. The Avengers might initially be on the defensive against Loki's children. Maybe Loki's children would have unique powers that the Avengers have to figure out how to counter. For example, if one of them can manipulate minds, it would cause a lot of chaos within the Avengers' ranks.
Well, obviously Harry would be one of the main characters as the story seems to revolve around him being the son of a god and Loki. Loki himself would also be a significant character. He could be a complex figure, perhaps mentoring Harry in some ways while also having his own devious motives. And then there would likely be other gods and goddesses who interact with Harry, either as friends, foes, or relatives.
There could be other supporting characters too. Maybe some of Harry's friends from Hogwarts like Hermione and Ron could make an appearance in the fanfiction. They might be initially skeptical of Carskile but then grow to accept him. And on Carskile's side, he could have his own set of friends or family members who play a role in the story, for example, his sister who gives him advice on how to deal with Harry.
Obviously, Robin would be one of the main characters. And then, of course, the Avengers members like Iron Man, Captain America, Thor, etc. would be there as well.
Obviously, Draco Malfoy and Dudley Dursley are the main characters. Draco, with his blond hair and aristocratic air, is a well - known Slytherin from the Harry Potter series. Dudley, on the other hand, is Harry's cousin, a rather large and spoiled Muggle boy. Their encounter would be the central focus of this fanfiction.
Well, in addition to the obvious ones, there could be some secondary characters that play important roles. For instance, Miles' friends or family from his universe might be involved. They could add a different perspective to the story. And on the Avengers side, characters like Black Widow or Hawkeye could have some interesting interactions with Miles. Black Widow could teach Miles some spy - like skills perhaps, while Hawkeye could show him some new archery techniques if Miles was interested. They all together would make the story more rich and engaging.
