I admit, I may have let my personal impressions of her seep into that expression…

Kind of odd to think that the character that most easily fits the “recurring villain” role in MLP is Diamond Tiara. I suppose she should just be considered an antagonist, as she hasn’t enslaved Ponyville like Trixie, or tried to bring about eternal chaos or night, or conquer and feed off the love of Equestria. However, for pure, sustained, petty meanness for no particular reason it’s hard to beat little kids, and Diamond Tiara seems to relish in tormenting the CMC.

I wonder what will become of her? Is she doomed to be a nasty piece of work for life, or will she grow out of it?
