Harry Potter would be the central figure as he is the protagonist in his own series. Ron could also be there, providing his usual comic relief and loyalty. As for Pokémon characters, it could be that a trainer from the Pokémon world somehow gets transported to Hogwarts. This trainer, along with their Pokémon, could become main characters. For instance, Ash Ketchum and his Pikachu could end up in the wizarding world. Harry, Ron, and Hermione would then interact with them, leading to all sorts of interesting situations. They could learn from each other's worlds, like the Pokémon trainer learning about magic and the Hogwarts students learning about Pokémon catching and training.
In addition to Harry, Neville could be a main character in this fanfiction. He has a connection to the magical creatures in the Harry Potter world already. And from the Pokémon side, a Pokémon like Charmander could be a main character. Imagine Neville befriending Charmander and trying to figure out how to take care of it in the Hogwarts environment. They could face challenges together, like dealing with other students who might be scared of the Pokémon or trying to hide it from the professors.
Obviously, Harry Potter would be one of the main characters. And maybe Hermione, since she's always interested in new and strange things. Also, a Pokémon like Pikachu could be a sort of main character in its own way, as it's the iconic Pokémon.
Obviously, Harry Potter himself would be a main character. He is the heart of any Hogwarts - related story. Also, Ron Weasley and Hermione Granger, as they are Harry's closest friends and would surely be part of his first Christmas at Hogwarts.
Well, it could be about Harry Potter somehow finding a Pokémon in the wizarding world. Maybe a Pokémon gets magically transported there, and Harry has to figure out what it is and how to deal with it.
There could also be a trainer who is jealous of Harry's unique abilities, being reborn from the Harry Potter world. This trainer might try to undermine Harry at every turn, stealing his Pokemon or sabotaging his battles, much like Draco Malfoy was often in conflict with Harry in the original Harry Potter series.
It could be Neville Longbottom. Neville is often overlooked in the Harry Potter series. He could be the one to discover a neglected Pokemon, like a Bulbasaur that has lost its trainer. Neville, with his kind heart and new - found confidence, decides to take care of the Bulbasaur. He uses his skills in Herbology to help the Bulbasaur thrive, and they form a great team.
Obviously, Harry Potter would be one of the main characters. And the first vampire would be a central figure too. There might also be characters like Hermione and Ron, who could be involved in the story in different ways. For example, Hermione might be researching about vampires to help Harry understand the situation better.
It could be Voldemort who somehow follows Harry into the Pokemon world. He might try to use the power of Pokemon to regain his strength and take over both the wizarding world and the Pokemon world. His dark magic could corrupt some of the Pokemon, turning them into his minions.
Neville Longbottom could be a main character. He has always had the potential for great things and in a world without Harry, he would be likely to step into the spotlight. He has the courage and the connection to Hogwarts that could make him a central figure in the fight against evil.
Hermione could be there. She would be eager to study the different magics and books in Tamriel. Her intelligence would help Harry navigate the new world.
Hermione could be a main character. As a very intelligent witch, she might assist Harry in his teaching, like helping him prepare complex lessons or providing additional knowledge to the students. For example, when Harry is teaching about ancient spells, Hermione could offer insights from the books she has read.
Hermione could be one. She could come to Degrassi to help Harry. She'd be really good at handling the academic side of things there, like helping students with their studies. And also, she could use her magic knowledge to figure out any magical mysteries.
