Well, often Harry is written as Loki when the author gives him Loki's cunning and mischievous nature. Also, there could be storylines where he inherits Loki's abilities or has encounters in the realm of Asgard.
In some fanfictions, Harry might have Loki's powers or personality traits. Maybe he uses magic in a similar style to Loki's tricks.
One common way is through arranged marriages. In some fanfics, pure - blood families arrange marriages to preserve their bloodlines or gain power. Another way is that the Ministry of Magic has strict regulations about inter - species marriages, like between wizards and veelas.
Well, in some fanfics, Naruto might have Starkiller's powers or similar fighting styles. Maybe he uses force abilities or has a lightsaber-like weapon.
In fanfiction, Arcturus Black may help Harry through magical artifacts. The Black family is likely to have a collection of powerful and rare magical artifacts. He could give Harry access to these artifacts, like a magical amulet that offers protection or a wand with special properties. This would give Harry an edge in his battles and his overall growth as a wizard.
The fanfiction might show Naruto with enhanced stealth skills and a better understanding of ninja tactics.
In fanfiction, Loki's pets can be a reflection of his personality. If he has a sly snake as a pet, it shows his devious side. The snake could slither around, spying on others for Loki. His pets could also be a source of conflict. Maybe his pet unicorn is seen as a dangerous beast by the Asgardians, and Loki has to defend it. Or his pet beaver is constantly building dams in places it shouldn't, and Loki has to deal with the consequences of his pet's actions.
One way is through magic. Loki is a master of sorcery. He could have used a powerful spell to create an illusion of his death while he actually teleported away. Another possibility is that he made a deal with some other powerful being. Maybe he promised something in exchange for his life and the being intervened when Thanos was about to kill him.
One common way is through her body language. She might use a sultry look or a seductive pose to draw attention. Another way could be her use of words, speaking in a soft, alluring voice. For example, she might whisper something suggestive to a character she wants to influence.
One main theme is the struggle with identity. Harry, being in Loki's shoes, has to grapple with a new identity that is quite different from his own. Another theme could be power dynamics. Since both characters have different kinds of powers, seeing how they interact and conflict in the fanfiction can be really interesting.
Well, in the world of fanfiction, just about any concept can be explored, so it's highly likely that there is a 'harry potter is loki reincarnated' fanfiction. Writers love to mash up different universes and characters. This particular concept could bring in elements of Loki's mischievous nature into Harry's character, creating a whole new set of adventures and challenges for him in the Hogwarts setting.
There are definitely some out there. These fanfictions often take creative liberties. For example, they might have Harry being reincarnated as Loki or some sort of magical crossover where Harry gains Loki - like powers. It's really fascinating to see how different universes collide in these stories.
