This is Rasiren, odd name isn't it. She was a formal siren ruler that wanted to take over MLP! But you would want her because after she was defeated and a pony once more she promised that whoever would care for her she would care for back.
Crystal Sun Crystal (obviously) is a Crystal Pony and is the cousin of Krystal Heart. She is a bit of a beauty queen but has good intentions. She likes to accessorize, and wants to someday own a fashion shop with her cousin.
