Well, an OC in a Harry Potter fanfic might be a transfer student from a foreign wizarding school. This character could introduce different magical cultures and spells. For example, they might know a spell for instant weather change that Hogwarts students have never heard of. Or an OC could be a house - elf with unusual powers. Instead of being subservient, this house - elf could have the power to resist dark magic better than most wizards. Also, an OC could be a wizard with a photographic memory for spells, which causes some chaos as they sometimes accidentally cast spells they just read about.
One interesting concept could be an OC (original character) who is a muggle - born witch but has a unique ability to communicate with magical creatures in a way that even Hagrid doesn't fully understand. Another could be an OC who is a descendant of an ancient and almost forgotten wizarding family, bringing back old spells and traditions. And there could also be an OC who is a squib but manages to find a way to contribute to the wizarding world in a non - magical yet crucial way, like being an expert in wizarding history and artifacts.
