More specifically, consider the following examples:
- Say my protagonist is a boy who has a lightning-bolt scar on his forehead, wears round glasses, and has dark hair and green eyes. His name is NOT Harry Potter, he is NOT a wizard, and he DOESN'T attend Hogwarts.
Would this be considered copyright? After all, it's perfectly plausible that there could exist a person with these physical attributes.
- Can my protagonist have a nickname like "Harry Potter" or "the muggle Harry Potter"? (again assuming he's not a wizard etc.)
