One way to make it interesting is to focus on the clash of their powers. Harry's magic is based on spells and potions, while Hela has her own set of god - like abilities. Their interactions in a battle or a situation where they need to cooperate could be exciting.
To make a Harry Potter - Hela fanfiction interesting, you could play with the idea of character development. Imagine Harry being influenced by Hela's ruthlessness and having to grapple with his own moral compass. On the other hand, Hela could be affected by Harry's sense of friendship and loyalty. This internal struggle within the characters, combined with the external conflicts that would surely arise from their different worlds colliding, would make for a really engaging fanfiction. You could also introduce new magical elements or artifacts that are a blend of both universes, such as a wand that can also channel Hela's power, or a spell book that contains knowledge from both the wizarding world and Hela's domain.
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.
To find quality Harry Potter hela fanfiction, consider following some well - known fanfiction authors. If you come across a really good story, check out the author's other works. They might have a consistent style that you enjoy. Additionally, look for fanfiction that has been around for a while and has a lot of reviews. This usually indicates that it has been read and liked by many fans, and is likely to be of good quality.
A possible fanfiction is one where Lady Hela is a time - traveling character who ends up in the 'Harry Potter' universe during the time of Voldemort's rise. She could either help or hinder Harry's fight against Voldemort, depending on her motives. Her knowledge from her own realm could be used to either save or destroy the wizarding world.
One idea could be that Hela somehow ends up in the wizarding world. She might be intrigued by the magic there which is different from her own powers. Maybe she tries to take over Hogwarts, thinking it's a place of great power. Another could be that Harry Potter has to team up with Hela to defeat a common enemy that threatens both the wizarding world and Asgard.
By adding magical elements to his situation. For example, he could try to use a spell to hold it in, but the spell goes wrong and he starts floating around instead. This would create chaos and humor.
To make it interesting, you could focus on the clash of different power systems. Supergirl's super strength and flight against the magic of Harry Potter. And use the lemon as a unique element, like a lemon - scented spell that only Supergirl can smell and it leads her to a hidden part of Hogwarts. This kind of unique combination of elements can draw readers in.
One idea could be that Harry discovers his true mother is Hela and has to deal with the new identity. He might face discrimination from some in the wizarding world who fear Hela's reputation. Another could be that he inherits some of Hela's powers, like the ability to control the dead in a more magical way than normal necromancy in the Harry Potter universe.
One way is to focus on their different worlds. Let Harry introduce Batman to the wonders of Diagon Alley or Hogwarts. And Batman can show Harry the Batcave. Another way is to create a common enemy that forces them to work together, like a dark wizard - mob boss hybrid.
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.
Yes, there might be some fanfiction exploring such an unusual pairing. Fanfiction writers often come up with creative and unexpected relationships. However, this would be a very unique crossover as Harry Potter is from the wizarding world created by J.K. Rowling and Hela is from the Marvel universe.
