It could be a very tense meeting. Harry, being used to the more straightforward magic of his world, would be on guard against Fem Loki's unpredictable and often chaotic magic. He might initially see her as a threat.
In a more serious scenario, Fem Loki could sense the power within Harry, especially the piece of Voldemort's soul. She might be intrigued and offer her help in getting rid of it, seeing it as a unique challenge. Harry would be hesitant at first but then realize that her powers could be useful.
The meeting between them in fanfiction could be quite intense. Harry Potter, coming from a world where good and evil are clearly defined by magic and the nature of spells, would be faced with the Joker, whose evil is based on pure insanity and a love for chaos. Harry might try to reason with the Joker at first, using his own sense of justice. But the Joker would probably just laugh at him and start creating havoc. This could lead to a battle of wits and powers, with Harry having to figure out how to deal with an enemy who doesn't follow the rules he's used to.
The relationship could be quite complex. Loki might see Harry as an interesting project, someone he can mold to his own liking. Harry, on the other hand, might be initially wary of Loki but gradually come to respect his skills. They could have a mentor - mentee relationship where Loki imparts his knowledge but also tries to influence Harry's actions.
It would be quite interesting. For example, Harry Potter would be very curious about Ms Marvel's powers. He has seen magic all his life, but her abilities are different. Ms Marvel, on the other hand, would be amazed by the magic in Hogwarts. She might try to figure out how it works using her scientific knowledge.
Well, in such a fanfiction, the story could start with Loki somehow finding himself in the Harry Potter universe. As Fem Harry Potter's father, he might have a different view on the whole wizarding society. He could introduce her to a more chaotic and unpredictable form of magic, as opposed to the more structured magic in Hogwarts. Also, his relationship with other characters in the Harry Potter world, like Dumbledore or Voldemort, would be really fascinating to explore. For instance, Loki might see Voldemort as a rival in terms of power and try to outwit him in his own sneaky ways. And his presence would surely stir up a lot of drama and new plotlines in the otherwise familiar world of Harry Potter.
Loki is used to being in a world of power plays and politics in Asgard. Fem Harry Potter, coming from the more straightforward (although not without its own intrigues) wizarding world, would bring a fresh perspective. Their personalities would clash at times, but also complement each other. Harry's loyalty to her friends and her belief in the power of love could rub off on Loki, while Loki's adaptability and his knowledge of different magics could enhance Harry's abilities.
It could be a wild ride. Loki would bring his own brand of chaos to the wizarding world. He might start by using his illusions to mess with the Hogwarts students during exams, making them see their worst fears instead of the exam papers. His relationship with the professors would be complex. Some, like Snape, might be immediately suspicious of him, while others like McGonagall might try to keep him in line. And his interactions with the trio - Harry, Ron and Hermione - would be full of surprises. He could either be an ally or a foe, depending on his mood and his goals at the time.
In fanfiction, their meeting could start with a bit of confusion. Harry, coming from his world of wands and spells, might not immediately understand Gandalf's more nature - based and ancient magic. But as they start to talk, they would find common ground in their fight against evil. Gandalf could sense the great burden Harry carries, just like Frodo did in Middle - earth. And Harry would be amazed by Gandalf's tales of far - off lands and great battles. It would be a meeting that bridges two very different magical universes.
The meeting could be described as a tense and strange encounter. Harry, in his Hogwarts robes, standing before the imposing figure of Ares. There would be a sense of unease in the air as their two worlds collide. Ares might be clad in his battle armor, looking down at Harry with a mixture of curiosity and contempt. The setting could be a desolate place, perhaps a cross between the Forbidden Forest and a Greek battlefield.
Well, in the original Harry Potter story, Harry meets a lot of magical beings within the wizarding world. But if it's fem Harry Potter meeting Hades, it's a whole different realm. She'd be in a much darker, more foreboding place. Instead of Hogwarts corridors, it'd be the gloomy underworld. And Hades is not like any of the characters in the wizarding world. He has his own set of rules and powers that are completely alien to what fem Harry is used to.
The plot could change significantly. For one, it might introduce new elements of magic. Also, the relationship between them could lead to new alliances or enemies.
