Hmm lets see not to good with this stuff but here we go. I'm 21 and have watched Sailor Moon since I was in elementary school. I know I had a period of time in which I took a break from the series in high school that was until I decided to make my ex boyfriend watch the series (he hated it but eh I enjoyed every second of it.) my favorite villains are a tie between several the shittenou, Diamond, Black Lady, Mistress 9, Sailor Iron Mouse, and Sailor Tin Nyanko. There were a few more I liked but for the most part those are the main one's.
