My deepest, darkest secret is that I love My Little Pony (so not particularly deep and dark afterall lol). I had vintage ponies as a child... regarding the FIM series, at first I was quite but watched more and more episodes and as time went by I decided that it was a hilarious show. There are so many weird and wonderful references that I often forget I'm watching a kid's program. I have no idea what the fandom is like - and I never want to know.
Here's my Nightmare Moon figure. She's the only one I have, but I love her
