THIS IS PROBABLY OFF TOPIC BUT THERE ARE PONIES ALL OVER MY SCREEN!!
Well this one's name is Fluttershy; she has a passion for animals/taking care of them/
mind controlling them/etc.
she obtained her Cutie Mark by falling from the sky and landing on a bunch of dark matter butterflies; they catch her, of course; and from that moment she dedicates herself to being the friend of all god's creatures. Also shes the only one who isn't racist towards the more intelligent species, as evidenced by how everyone else calls Iron Will a monster, and Shy keeps correcting them on how hes actually a minotaur.
