Who would you say is the most prominent or iconic villain of the series?

Nightmare Moon - First main villain, first enemy the Mane 6 fight together, and appears in a flashback for an epic battle with Celestia.

Discord - Appears in the most episodes (not counting Luna appearances as NMM), though redeemed for most of them, kinda plays an antagonistic role in his third, and is responsible for the threat in Princess Twilight Sparkle

Queen Chrysalis - Fan-favorite villain (since Discord lost votes for turning good), and a Knight of Cerebus, though forgotten by all the ponies (and half of the bronies)

King Sombra - Possibly the one behind Nightmare Moon though nothing has confirmed this, and darkest villain in the show (possible exception of Demon Sunset Shimmer though she is way less intelligent than him)

And of course all are villains of a two-parter

Taking everything into account, I'd have to go with Discord but what are your thoughts?
