Well, Harry Potter for sure. Hela is a main character as it's about him being her master. It's possible that Dumbledore or other Hogwarts professors could be involved in some way, perhaps through magical connections or prophecies. And there could be some antagonists from Hela's world who don't like the idea of Harry being in control and they would be important characters in the story as well.
It's hard to say precisely without reading it. But generally, in such a fanfiction, Harry Potter would be in a very different and probably challenging situation as the master of Hela. It could be that he has to navigate the politics and power struggles in a world related to Hela. He may also have to face enemies who are after Hela's power or want to oppose Harry's new role.
Hela would likely be more powerful. She is a goddess in the Marvel universe with superhuman strength, the ability to summon weapons, and immortality. Harry Potter, while very powerful in the wizarding world, has limits to his magic. His spells and abilities are mainly within the realm of magic that wizards understand. Hela's powers seem more raw and on a much larger scale compared to Harry's.
Yes, there are some. You can try searching on fanfiction websites like Archive of Our Own. There are often creative takes on combining the worlds of Harry Potter and the concept of the Master of Death with Hela from other mythologies. Some may explore how Harry's powers as the Master of Death could interact with Hela's abilities.
Dumbledore and Lady Hela would be an interesting combination. Dumbledore's wisdom and Hela's power could lead to some intense and thought - provoking interactions. They could be on opposing sides at first, but then find common ground in their goals for the wizarding world.
Common themes include the struggle for control. Harry has a certain kind of control over death, and Hela has control over death in her own realm. So, there can be a battle or negotiation over who has more power in the realm of death. Also, themes of redemption can be present. Maybe Harry tries to redeem Hela, or vice versa, as they both have complex relationships with death and power.
Harry Potter would definitely be one of the main characters since it's in his name. There might also be his friends like Hermione and Ron. They could play important roles in helping Harry with his journey to master fire or in dealing with the consequences of his new power.
Harry Potter is most likely one of the main characters, since his name is in the title. He is probably the one who is the master of shadows. Hermione and Ron could also be main characters as they are Harry's closest friends in the original series and would likely be involved in his new adventures related to being a master of shadows.
Often, there could be an original character as the weapon master. This character might be a self - taught wizard who has a natural affinity for weapons. There could also be appearances from the well - known Harry Potter characters like Harry himself, who might seek the weapon master's help in times of need. Maybe Hermione would be interested in the knowledge of the weapon master regarding the magical properties of different materials used in weapons.
Obviously, Harry Potter is one of the main characters as it's about his mastery of illusions. His friends like Hermione and Ron are likely to be important as well. They would probably support Harry in his journey to master this new skill and use it for good.
Well, surely the illusion master would be one of the main characters. But there could also be some of the original Harry Potter characters like Harry, Hermione, and Ron. They might interact with the illusion master, either as friends or as people who are initially skeptical of this new form of magic.
