The Harry Potter franchise has introduced many iconic characters over the years, from the tragic Severus Snape to the wise Albus Dumbledore. But even the names that weren't always prominent in the books or movies had growth of their own that helped define them. Neville Longbottom has always been a great example as he started as a brave but timid wizard who evolved into a hero that played a key role in killing Lord Voldemort. There was also the quirky and kind Luna Lovegood, who played a key role in the larger narrative.
