Well, there could be a fanfiction where Harry Potter becomes an evil wizard due to a misinterpretation of a prophecy. He might think that the only way to save the wizarding world is to rule it with an iron fist. So, he starts to hunt down anyone who opposes him, including his former friends. In this kind of fanfiction, the author usually changes Harry's personality completely, making him cold - hearted and power - hungry.
There could be many interesting fanfictions in this category. One possibility is that the mummy could be a magical creation from the wizarding world, perhaps brought to life by a dark wizard and Harry Potter has to stop it. Another idea could be that the mummy has some sort of connection to an ancient Egyptian magic that Hogwarts is now dealing with.
Since lemon fanfiction often involves inappropriate content, I can't really discuss the common themes in that context. But in general 'The Mummy 2017' fanfiction might have themes like adventure, the struggle between good and evil, and the exploration of ancient curses.
Well, a major theme is the exploration of new powers. Shapeshifting is a unique ability, and in these fanfics, we often see the characters discover the limits and potential of this power. They might experiment with different forms and how each form can be useful in different situations. Also, friendship is a common theme. The shapeshifter forms bonds with Harry, Hermione, Ron and other characters, and these relationships are developed as they face challenges together, like dealing with dark wizards or solving magical mysteries.
The original Harry Potter story is centered around Harry as the protagonist who fights against evil. However, in 'evil hsrry potter fanfiction', the whole narrative flips. Harry becomes the source of chaos and malevolence. His actions, which in the original were for the good of the wizarding world, are now for his own dark desires. His relationships also change completely. Instead of being friends with Ron and Hermione, he might be their enemy. The entire moral compass of the story is reversed, creating a very different and often darker version of the wizarding world we know.
Sure, it's quite possible. Fanfiction writers love to blend different fictional worlds. In a 'The Mummy (2017)' and 'Harry Potter' crossover, we could see the mummy's powers being pitted against the spells of Hogwarts students. Maybe the mummy is brought back to life in the wizarding world and causes chaos. There are endless possibilities for interesting storylines in such a crossover fanfiction.
It could be Harry Potter himself. He might be on a new adventure that involves the mummy mystery. His skills in magic would be crucial in this new setting.
Adventure is another common factor. Whether it's Harry's adventures in the wizarding world or the characters in 'The Mummy' exploring tombs, fanfictions usually blend these adventure aspects. For example, a fanfic might have Harry and his friends exploring an Egyptian tomb full of mummies and magical traps, just like they would explore a hidden part of Hogwarts.
Yes, one popular theme is the clash of magic systems. The magic in Harry Potter is very different from any sort of power or 'curse' related to the mummy. So, fanfictions often explore how these two different forms of magic interact. For example, if a spell from Harry Potter was cast on the mummy, what would happen? Another theme is the exploration of different cultures. 'The Mummy (2017)' has elements of ancient Egyptian culture, while Harry Potter has its own rich wizarding culture. Fanfictions may combine these cultures in interesting ways.
The plot could involve a mummy that has been awakened in the wizarding world. It might be seeking revenge for something that happened in the past. Harry Potter, being the hero, would have to find a way to stop it. He could use his spells and knowledge of magic to try and defeat the mummy.
