Starlight Glimmer; Again as, I already mentioned in a previous post, her back story is not at all convincing, just because she lost her friend at a young age she become some kind of psychotic jealous cutie mark stealer????
She doesn't even have a legitimate reason to be evil and what she did to her village was an unnecessary stretch over something so trivial, she lost A friend wow.
She's a pony that shouldn't have even needed to be reformed because she isn't a convincing villain.
