Out of all the characters in the show, it can be easy to argue that Twilight is the one that grew the most in her journey over the course of nine seasons. Starting as a student, growing into an alicorn and then taking the place of Celestia and Luna in the end. Can't say that any others have had an arc that was as far-reaching as hers for the fate of Equestria.
While there were bumps in the road for the fandom to adjust to these new changes, such as when Twilight got her wings, it has given the fandom much to work with when it comes to fan creations and theories. What sort of episodes would you have liked to have seen from Twilight, for instance? Or what about her character arc would you have changed?
