What? no option for Discord? this thread is flawed!
I vote either Discord, or the Space Sphere, maybe the Fact Sphere…
Oops, I’m mixing MLP and Portal 2 again, sorry…
I’d be Minty. The tragically left in the 80s outsider…
Definitely Twilight Sparkle.
I’m just throwing this in the mix, but if you want a really awkward look, when your boss mentions “Man, my four-year-old daughter is really into MLP:FIM” reply (as a 30-year-old man, childless) “Yeah, that show is great!”
I’d heard about it but hadn’t actually watched any of the episodes. I’m currently working through 'em.
I’m Pinkie Pie with a sprinkle of Twilight Sparkle. PP is definitely my favorite Pony.
I’m Pinkie Pie through and through, but deep down where my secrets are, I want to be Rarity.
Looks like the Wall Street Journal just got 20% cooler. 
Sigh. Just once, I’d love to see an article that looks into why adults are enjoying the show, rather than just being about the “brony” phenomenon. It just reinforces the idea that the adult fanbase for MLP:FiM is either (a) purely ironic or (b) comprises socially inept shut-ins who get off on cartoons. Or both.
Ah well. There are worse injustices in the world, to be certain.

There is evidence that Pinkie Pie is a Mare of Diomedes.
She likes mustard on her hot dogs. Think about that a bit.
Ooh, I want to be one too.
Makes me laugh every time.
It’s a toss-up between Twilight and Pinkie, but I went with Twilight.
