It would probably involve a crossover of the two universes. Harry Potter might encounter Deidara's unique form of art which is explosive in nature. There could be battles where magic and explosive art are pitted against each other.
It might involve Harry having Wolverine - like abilities. Maybe he could have retractable claws made of magic instead of adamantium. He could use these claws in battles against Voldemort and his Death Eaters. Also, Harry could inherit Wolverine's healing factor, which would make him even more difficult to defeat. The story could also have Wolverine - type characters in the wizarding world, like a wizard with a similar tough - guy attitude and a penchant for fighting.
In such a fanfiction, it could be that Atreus has somehow ended up in Hogwarts. There could be a conflict between the students who are suspicious of this new arrival and Harry has to step in to protect Atreus. Harry would likely use his knowledge of the magical world and his courage to ensure Atreus's safety. He might also introduce Atreus to the wonders of magic, like flying on a broomstick or using potions to heal wounds.
Well, it might involve a lot of things. First, Harry Potter as a werewolf would likely have to navigate the Twilight - style werewolf pack dynamics. He might have a new set of powers or limitations based on how werewolves are portrayed in Twilight. There could be a whole new set of relationships formed, perhaps with Twilight's vampires or other werewolves. And it would also likely include some sort of conflict or adventure that combines elements from both the Harry Potter and Twilight worlds, like fighting a dark wizard who also has some connection to the Twilight vampires or something.
It might involve a lot of world - building around the relationship. Since Merope Gaunt is from an old and rather dark wizarding family, there could be elements of her family's influence on their relationship. And for Harry, his more modern - day values might clash with the traditional ways of the Gaunt family.
The story could have a plot where Harry Potter is on a quest in the world of 'Avatar' and needs to bond with an ikran to complete his mission. He would have to learn the ways of the Na'vi to gain the ikran's trust. There could be elements of his Hogwarts training that he uses in this new world, like his courage and problem - solving skills. It would also likely involve his friends, who might either be with him or he would be trying to get back to them. And of course, there would be descriptions of the beautiful landscapes of Pandora and the unique magic that the ikran possess.
It might involve Naruto having some Targaryen - like features. Maybe he has the signature Targaryen silver hair and purple eyes. And of course, there could be dragons involved. Naruto could form a special bond with a dragon, similar to how he bonds with his summons in the original Naruto series.
Probably not. In the wizarding world, they don't really have the concept of Muggle fanfiction in the same way. And Harry is often quite busy with his own wizarding affairs, like dealing with dark wizards and protecting Hogwarts. So it's not very likely he'd stumble upon AVPM fanfiction.
A fanfiction might center around the relationship between Harry and the panther. They could share emotions deeply. When Harry is sad, the panther could comfort him. And when there's danger, the panther would be fierce in protecting Harry. It would be like a deep, spiritual connection between them.
It might involve Harry being a big fan of the Cullen family. Maybe he reads about them in some sort of magical book that bridges the two universes. He could be intrigued by their vampire lifestyle and how they interact with humans in their world.
It would likely include elements of both Harry Potter and the Daedric Prince lore. For example, Harry might have some special abilities or a new identity related to the Daedric Princes. There could be new magical creatures from the Daedric Prince world introduced into the Harry Potter universe, or vice versa.
