They can fit in various ways. For example, they could be part of a new threat that the Hogwarts students have to face. The Dothraki's combat skills and fearless nature would make them formidable opponents.
Yes, there might be. Some fanfiction authors like to blend different fictional universes. They could create a scenario where a Dothraki character somehow enters the world of Harry Potter, perhaps as a foreign exchange student of sorts at Hogwarts. This could lead to interesting interactions with the wizarding world's characters, like the Dothraki's unique combat skills and cultural values clashing or meshing with the magic - based society of Harry Potter.
Some fanfictions make Arrancar into students at Hogwarts. This is really interesting as they have to adapt to the rules and the way of life at Hogwarts. They might have trouble with things like the House system or following the instructions of the professors, given their different upbringing in the Arrancar world. Their combat - based powers can also make them stand out in classes like Defense Against the Dark Arts.
In fanfiction, changelings can fit into the Harry Potter universe in various ways. They could be part of the magical creatures' lore. For example, they might be related to the concept of shape - shifting, like Animagi but with a different origin. Maybe they are a result of some ancient magic gone wrong or right.
One main theme is the clash of cultures. The magical and often more civilized world of Harry Potter against the wild and war - like Dothraki culture. For example, in many fanfics, the Dothraki's view on honor and combat is contrasted with the values of the wizarding world.
Muggle guns can add an interesting twist to the fanfiction universe. They can be used as a symbol of the Muggle world intruding into the wizarding one. For example, a wizard might accidentally discover a gun and be both fascinated and terrified by it.
They could fit in as a new and powerful force. Maybe they are hidden in the shadows, secretly influencing events. For example, they could be behind some of the dark magic incidents that happen in the fanfiction.
Shadow elementals in 'Harry Potter' fanfiction could be a part of an ancient magic that has been long forgotten. They might be connected to the founding of Hogwarts itself. Maybe the founders had to deal with shadow elementals when they first built the school, and now they are starting to resurface. This would create a really interesting backstory and connection to the original lore of the series. Also, shadow elementals could interact with existing magical creatures. For instance, they could form a symbiotic relationship with dementors, making them even more terrifying.
They can add new dimensions to the existing magic system. For instance, if there are powerful elementals, it could change the power dynamics among the characters. They might be seen as a new threat or a new ally. The Hogwarts curriculum could potentially expand to include the study of these elementals if they become more prevalent in the fanfiction.
Storm flames can be seen as a new type of magic in fanfiction. They could be something that is unique to a certain region in the wizarding world, like a far - off magical land that has not been explored much in the original books. For example, a wizard from that land comes to Hogwarts and brings the knowledge of storm flames with them.
The Infinity Stones could also change the magic system. In the Harry Potter universe, magic has certain rules and limitations. But with the introduction of the Infinity Stones, those rules could be bent or broken. For example, a character could use an Infinity Stone to perform magic without a wand, or to teleport across great distances without using apparition. This would create a whole new set of challenges and opportunities for the characters in the fanfiction.
