How could Pikachu fit into the Harry Potter universe in a fanfic?

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 Dixon Brothers could be muggles who are accidentally exposed to the wizarding world. They might start out as skeptics but then become intrigued. For example, they could be neighbors of the Weasleys when they are on a mission in the non - magical world. Harry Potter could then be the one to introduce them to the wonders of magic and they could help Harry in some way, like using their street - smart skills to navigate a dangerous part of the non - magical world where a dark wizard is hiding.

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.

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.

One way is through his magic. His spells could be in a state of superposition. So a spell like 'Expelliarmus' could be both cast successfully and not cast at all until some 'measurement' in the story. For example, if he casts it at an enemy, the enemy's reaction could be both disarmed and still armed until the moment of impact, which is like the 'observation' in Schrödinger's experiment.

One way could be through a powerful dark wizard's experiment. Maybe a wizard, seeking ultimate power, discovers a way to bring the Infinity Stones into the magical world. They could be hidden as powerful magical artifacts, and their powers might be harnessed in a way similar to how wizards use magic. For example, the Time Stone could be used to manipulate time within the wizarding world, perhaps to reverse a tragic event or to gain an advantage in a battle.

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.
