Even though I agree with the amazing atheist on most things there are a few things I disagree with him on.
Out of curiosity I looked up the search term "My Little Pony" on Yahoo from a REALLY long time ago to see what kind of results I would get, and bronies/pegasisters were DEFINITELY a thing way back when. (But they weren't called that back then, obviously.) There was even fan art and fan fiction sites back then! I didn't even know fan fiction was a thing back then.
I'm trying to imagine that if all the major FiM villains were Pokemon trainers, what their signature Pokemon would be? Here's what I came up with:
Cozy Glow: Marshadow
King Sombra: Darkrai
Lord Tirek: Giratina
Queen Chrysalis: Genesect
I think I made some pretty good picks.
