Imagine Harry Potter in Asgard as the Master of Death. He could be drawn into the political intrigue of Asgard. His power over death could make some of the Asgardian nobles fear him, while others might try to use him for their own gain. He could end up in the middle of a power struggle between different factions in Asgard. At the same time, he might be exploring the magical properties of Asgard, comparing and contrasting them with the magic he grew up with in the wizarding world. His journey could lead to a new understanding of both his own power and the nature of the worlds he has experienced.
In this kind of fanfic, Harry might be initially seen as an outsider. But as he starts to use his powers as the Master of Death, he could gain respect. He could use his ability to communicate with the dead to gain knowledge about Asgard's past. This knowledge could be crucial in helping the Asgardians deal with a threat, like an ancient evil that is starting to rise again. He could also teach some of the younger Asgardians about the different forms of magic he knows, which could be a new and exciting concept for them.
Well, Harry could find that his Deathly Hallows are perceived very differently in Asgard. His Invisibility Cloak might be seen as a powerful magical artifact like the ones in Asgard. His Resurrection Stone could be a source of great fascination as Asgardians have their own beliefs about the afterlife. And his Elder Wand might be seen as a weapon of great power, perhaps on par with Mjolnir.
One possible fanfic could involve Harry Potter, with his newfound status as the Master of Death, being transported to Asgard. He might use his skills and powers to face the challenges there. For example, his ability to master death could give him an edge in battles against Asgardian foes. Maybe he'd form an alliance with Thor, and together they'd fight against a common enemy like Loki who has some new, more dangerous scheme.
He might be amazed by the grandeur of Asgard. Its golden palaces and powerful magic could both intrigue and intimidate him. Maybe he'd meet Thor and they'd exchange stories about their different kinds of magic and heroic deeds.
A great plot for such a fanfiction would be that the Asgardians initially mistake Harry Potter for a threat because of his title as Master of Death. But as they get to know him, they realize that he can be a great ally. Harry could learn about Asgardian magic and combine it with his own Deathly Hallows - based powers. For example, he could use his knowledge of the Elder Wand to enhance the power of an Asgardian weapon. This would lead to a series of adventures where Harry Potter helps Asgard while also learning about their culture and magic.
Well, perhaps Harry Potter, as the master of death, could bring some of his magical knowledge to the DC universe. He might use magic to outwit the villains in DC. For example, he could use the invisibility cloak to sneak up on the Joker or use a spell to stop Lex Luthor's evil plans.
He could interact with Thor. Harry might show Thor his Elder Wand and Thor could be impressed by its power. They could then team up for a battle against a common enemy, with Harry using his magic and Thor his hammer.
If Harry Potter goes to Asgard in fanfiction, he would likely be a fish out of water at first. The Asgardian culture, with its focus on honor and battle, would be quite different from the wizarding world he knows. He could end up befriending Loki, who might be intrigued by Harry's magical abilities. They could team up for some mischief or to solve a big problem that threatens both Asgard and the wizarding world. Harry's invisibility cloak, for example, could be a useful tool in Asgardian espionage.
First, Harry would need to prove himself. As the Master of Death, he has a certain aura about him. In Asgard, he could start by saving a village from a monster attack. His ability to speak with snakes (if he still has that Parseltongue ability) might come in handy when dealing with some of the more mysterious creatures in Asgard. He could also use his experience from the wizarding world's wars to strategize against Asgard's enemies. As he gains more and more respect, he becomes a hero, and the Asgardians might start to see him as a protector, like they do with Thor.
In a fanfic where Harry Potter meets Death, one possibility is that Death offers Harry a choice. Maybe it's a choice between saving his loved ones or sacrificing something of great value to him. This could lead to a moral dilemma for Harry, testing his character in ways not fully explored in the original series.
In this fanfic, Harry might face a situation where he has to bargain with Death. He could be trying to save a loved one from an untimely end. Death, being an all - knowing entity, might test Harry in various ways, like making him relive some of his most difficult memories to prove his worthiness for such a deal.
In such a fanfic, Harry Potter as the Master of Death would bring a whole new dynamic to the Justice League. His magical abilities are different from the superpowers of the League members. He might have to adjust to the more scientific and modern world of the Justice League while still relying on his old magical knowledge. And the League would have to learn to work with his rather unorthodox methods.
