Discord. He actually won. He corrupted the ponies, making the EoH useless. Only his arrogance and chronic self-defeatism caused him to lose in the end. He was also the de facto most powerful being in the show until they nerfed him to so that he didn't solve all the problems instantly after he turned good.
As a grown-up (arguably, anyway) I have to pick Starlight Glimmer, which is wholly apart from my being head over hooves for her. Her Leninist/dystopian cult was just so real-world creepy that any more "fantastical" villain pale by comparison.
The one that that keeps me from voting Glim Glam is that, while I love her as a villian, I love her much better as a member of the Mane 9. (it took 3 seasons to flip that '6' upside down... mathematically literal and timey wise)
nobody likes season 2 anymore and blames "nostalgia effect" for those who still love it. why is Discord so popular when people obsess over Season 5 and 7 so much?
Why is pony of shadows on here?
I find the fact the two shadow villains are at the bottom of the poll funny.
I picked Sombra because he is the onlyvillain who gave me some serious goosebumps. That was some REAL darkness.
Discord. You know, back when he was a villain and a good character. Not the shitty version they're feeding us.
By far my favorite Villain, and my 3rd favorite character, in MLP: FIM would be Queen Chrysalis =3
It's a pretty close fight for the number one slot for me, and would be even closer if I only considered Starlight Glimmer's first appearance, but in the end I've got to go with Discord; he didn't represent quite the same level of existential threat that Starlight promised in "The Cutie Map", but he was admittedly more entertaining and threatening, and John DeLancie's acting has been marvelous in his every appearance.
I'd give honorable mentions to Chrysalis, Nightmare Moon, and Pony of Shadows (in that order), a semi-honorable mention to Tirek, and a not-entirely-dishonorable mention to Sombra.
Kinda surprised at the lack of love for Nightmare Moon. Her background and motivation are the best out of all of these plus her alternate history form had a batpony army. Where's her loyal legion? Did they disband her forces or something?
Alright, actually just realized that I was only basing this off Discord's first appearance as a villain and Starlight's first appearance and also Chrysalis.
So in that case I would put
Starlight above all. Thought I would call more of an antagonist rather than a villain.
The way I will vote on this is on how engulfed I was by the villain and their character, not on the overall episode; of course, the "best" villain would have an overall effect on the episode.
Also some of these villains didn't have much about them.
I would say Discord, Starlight, and Tirek had the overall more captivating personalities. Discord was hilariously evil/chaotic, Starlight was pleasantly intelligent, and Tirek was menacingly deceitfully evil.
Hmmm.....I wanna vote for Starlight, but gunna have to give it to Discord
