However, one character who has become surprisingly important in the prequel films is Nagini, a character we knew only as a snake from the main series, but we learned was actually human in Fantastic Beasts: The Crimes of Grindelwald.
For serious fans of the Harry Potter franchise, the Fantastic Beasts movies have been a welcome addition to the canon.
While this revelation was a surprise to many, J.K. Rowling says it should not have been because the information was always there.
They have filled in a lot of backstory for different characters and events only referenced in the original novels.
