The top Harry Potter characters come from a rich universe crafted on the page and adapted to the screen, giving us some of the best movie adaptations from books of all time. Since the Harry Potter universe is one where there are 75 (75!) main characters in the Harry Potter movies and books, there's little surprise that they are some of the most beloved (and hated) characters of all time.
That said, the question in front of us is "who are the best Harry Potter characters?" and it is a tough one to answer. Do you go for the obvious and choose Harry the hero, or pay respect to Voldemort, one of the best movie villains of all time? Do you go for brains with Hermione or charm with George & Fred? These are the questions we're confronted with when attempting to name the greatest Harry Potter characters ever.
Since both the Harry Potter books and movies can be taken into account, it's up to you to decide if you want to vote for the popular Harry Potter characters as you imagined them or as they were portrayed on screen. Since the books are among the best selling series of all time, there's a good chance you've read them and can compare notes with the movies. Your choice is yours, though; nobody's breaking out the Imperius curse so cast your vote for your favorite characters and make vote down the ones you don't like. And if there's a supporting Harry Potter character you feel belongs on the list, make sure to add them to this list of the top Harry Potter characters. Of course, if you're forgetting some of the names or need pictures to jog your memory, you can use the list as a reference.
