The anti-bronies don't have their own OCs, of course (they only watch the show to find more things to hate yaknow!) but when they are pulled into Equestria, they find themselves in pony bodies anyway.

These are based on ponies from the original generation of My Little Pony, matched with the personalities of the villains from the original FLAP fics. They aren't meant to be the real G1 ponies - they're just appearances and identities pulled from some other dimension to force the humans into a suitable form for this world.

Talent: Sesquipedalian loquaciousness

Irwin is a focused, capable woman not averse to fighting. Irwin's main gimmick is that she talks in extremely long words, even and especially in situations where this actually obscures her meaning instead of making it more precise. As a woman she is tall, fit and permanently sour-faced. As a pony she's much the same.
