I’m sure this has been asked before on the old booru, but we may have picked up some new guys, or maybe your own answer changed (I know mine did).
 
My favorite pony is Trixie. I think that she has a lot of room for further development, and I like her voice, method of speech, color scheme and model, and her clothes. As far as her actions and personality are concerned, I think she gets far to much hatred for her actually minor transgressions. Rainbow Dash is massively arrogant, yet everyone loves her.
 
Anyway, this isn’t meant to become a Trixie discussion. This is about you guys and your favorite ponies.
