She was a small but very impactful part of my childhood back when I casually watched MLP: FiM, and the same reason why my love for the show was revived in recent years. I'll always be impressed by how she went from a generic high school villain to one of the greatest protagonists the franchise ever created. And I'll forever be miffed she never got a proper role in the main series, canon issues aside. (But that's what fanfictions are for!) Whether she's a pony or a human, Sunset will always have a special place in my heart.
