Well, first of all, the character could be introduced as a transfer student to Hogwarts, with their dual heritage being a well - kept secret at first. As they start to make friends and get involved in the daily life at Hogwarts, their Kryptonian powers would gradually show up in small ways. For example, they might be able to lift heavier objects with ease during Herbology class. In the Triwizard Tournament, if they participated, their powers would give them an advantage in the tasks. But they would also have to be careful not to expose their true nature too much, as it could attract unwanted attention from both the wizarding authorities and dark forces. Their relationship with other characters like Dumbledore would be very interesting, as Dumbledore would surely recognize the potential and the danger that comes with such a unique character.
It's a very out - of - the - box concept. But if we consider it, it could be seen as a magical anomaly. Just like there are other strange magical occurrences in the Harry Potter world. Maybe it's the result of a botched spell or a very rare magical condition.
Supergirl could be a foreign exchange student of sorts in the Harry Potter universe. She could be there to study magic while also sharing her own Kryptonian knowledge. Her superpowers would make her stand out, but she would also have to learn the rules of the wizarding world, like not using her powers when it's against the wizarding code.
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.
Well, in fanfiction, Merlin might be reincarnated in the Harry Potter era. He could retain some of his past memories and powers. As a character, he would bring a different style of magic, one that is more in tune with nature and less structured compared to what the wizards in Harry's world are used to. His arrival could cause a stir among the magical community, with some seeing him as a savior and others as a threat, all while having a special connection with Harry, perhaps as a mentor or a long - lost relative in the magical sense.
An amputee character can bring a new perspective. They can use magic to create prostheses or aids. For example, they might use a spell to make a magical limb that can do things normal prostheses can't. This adds a unique element to the magical world.
To write such fanfiction, you could start by creating a crossover point. Maybe a portal opens between the Kryptonian world and the wizarding world. Then, characters from both sides start to interact. A Kryptonian could be amazed by magic and try to learn it, while wizards could be in awe of the Kryptonian's raw power. You'd have to balance the two different power systems and cultures so that the story makes sense.
Tinkerbell could be a new kind of magical creature in the wizarding world. She might be discovered by Hagrid in the Forbidden Forest. Since she's so small, at first the wizards might mistake her for a really tiny pixie. But then they'd realize she has different powers, like being able to create light and fix things with her fairy dust.
Imagine an Aztec warrior as a protector of a powerful magical artifact that has some connection to the Harry Potter world. Voldemort is after this artifact, and the Aztec warrior teams up with Harry and his friends to keep it safe. Along the way, they learn from each other's cultures and magics.
He could fit in as a new kind of hero. His magic would be something unique compared to the existing powers in the Marvel world. He might join the Avengers and use his spells during battles. For example, he could stun enemies with a simple 'Stupefy' spell or create a large magical explosion with a more powerful incantation.
In a more complex fanfiction, a Sith Assassin could be the result of a long - lost experiment by a powerful but mad wizard who tried to combine the dark arts of the wizarding world with some unknown, extra - dimensional power that led to the creation of this Sith - like being. This being then has a connection to both the Sith ways and the magic of the Harry Potter universe. It could be on a quest to either gain more power or to find a way to belong in this strange world that it has been thrust into.
