@Chaypell13, hi there . Since we already had a topic lying around for talking about MLP villains and why we like them, I've merged your thread with the older one. Most people don't really distinguish between their "favorite" villain and the "best" villain anyway, and all that. Just helps to keep the discussion all in one place, and I hope you understand
For big, threatening, blockbuster villains I'd have to go with Discord. Everything from his voice, his attitude, his ability to torment each character and pick at them on an individual basis, he was a fantastic villain. I consider the episodes dedicated to their beating him to be among the strongest in the series, and he played a big part in that. I also consider him to be an even better villain for how he's willing to reflect on why he does what he does, and to just show more sides of himself than the other big guys. "Covering the land in candy and chocolate milk is fun, but so is having friends, but are they just holding me back from who I am, and I just wanna cause a little chaos and entropy, entropy, entropy..."

For the little, everyday people you feel like you could bump into on the street, I love Lighting Dust. I love her lack of empathy, I love her fierce drive for self-improvement, I love her messed up sense of priorities, and I love her contrasts with Rainbow Dash. I want more of her too, and her story feels unfinished.
