She would be a disruptor. Bellatrix's unpredictable and violent nature would immediately set her apart in the Game of Thrones world. She might not play by the political games' rules and just use her dark magic to get what she wants.
Bellatrix could find herself in the middle of the power struggles in Westeros. She may side with the most ruthless characters, like the Lannisters, because they share a similar thirst for power. Her skills in combat, which in the Harry Potter world are enhanced by magic, would give her an edge in battles in Game of Thrones. However, her loyalty to her own beliefs and her 'master' in the Potter world could lead to some interesting conflicts within the alliances she forms in the new world.
In a fanfic, Bellatrix would bring a new kind of magic to the Game of Thrones universe. Her knowledge of the dark arts could be both feared and coveted. She might be seen as a threat by some of the more traditional magic - users in Westeros. At the same time, her insanity could make her actions hard to predict. This could lead to some very unexpected story developments. For example, she could start a war between two kingdoms just because she felt like it or because she thought it would benefit her in some way.
A fanfic about Bellatrix in both Harry Potter and Game of Thrones could be a really wild concept. Maybe it could involve Bellatrix being transported to the world of Game of Thrones. She would likely be a powerful and feared figure there. Her dark magic skills from the Harry Potter world could make her a formidable opponent in the political and power - hungry environment of Game of Thrones. She might form alliances with some of the more devious characters in that world, like Littlefinger perhaps, and together they could scheme to gain more power.
The Dragonborn could potentially fit into the Game of Thrones universe in several ways. One way is through their dragon - related abilities. In Game of Thrones, dragons are a powerful and rare force. The Dragonborn's natural affinity for dragons could make them a valuable ally or a feared enemy. They could perhaps form alliances with the Targaryens, who also have a strong connection to dragons. Another aspect could be their combat skills. The Dragonborn is often a skilled warrior, and in the brutal world of Game of Thrones, such skills would be highly sought after.
Well, imagine if the ancient starship had some sort of artificial intelligence still active. In the Game of Thrones world, this would be seen as some kind of powerful spirit or demon. The AI could start influencing the events in Westeros, maybe by giving advice to certain characters. It could choose those who it thinks can bring about a new order or simply those who can help it repair itself. And this would create a whole new layer of intrigue and power struggles.
Dragons in 'Harry Potter' fanfics often serve as powerful and mysterious elements. They can be used as a plot device to introduce danger or adventure. For example, a dragon might be guarding a hidden treasure or a powerful magical object. In some fanfics, characters might form bonds with dragons, like in the books where Hagrid has an affinity for dangerous magical creatures.
A Wendigo could be a dark and mysterious addition. It could be part of a new threat that emerges from the Forbidden Forest. The magical creatures in the forest might be afraid of it, and it could start preying on students who wander too far. Harry and his friends would need to use spells like the Patronus to protect themselves.
Pikachu could be a special guest at Hogwarts. It might be brought there by a powerful wizard who has traveled to other dimensions. And it could use its electric attacks to protect the school from dark forces.
Alucard could fit as a powerful outsider. His vampiric abilities like super strength, speed, and the ability to turn into mist or a bat would be very different from normal wizard magic. He could be a sort of anti - hero, helping Harry when it suits his own goals. For example, if there was a dark wizard using blood magic in a way that threatened Alucard's existence too.
Dick Grayson could fit in as a new kind of hero in the wizarding world. He could use his detective skills, which he developed in the Batman universe, to solve magical mysteries. For example, if there were a series of strange disappearances in Hogsmeade, he could use his deductive reasoning to figure out what was going on, much like he did in Gotham.
The Sky Flame could fit as a new magical discovery. It might be found in a long - lost magical artifact or a hidden location. For instance, it could be hidden in a secret chamber in Hogwarts that the main characters stumble upon.
She could be a new transfer student with superpowers at Hogwarts who discovers she's pregnant. The professors and students would have to adjust to her powers and her situation, and she might have to deal with the prejudiced views of some in the wizarding world.
