Ok, so we're working on a new series of community based Final Fantasy top 10 lists. The easiest way I can think of to do it is to pick your 10 out of each list and the rankings will be based on how many votes each one gets. You don't need to provide explanations of everything, but feel free to add comments, especially on your favorites.

The first list is for your top ten villains. You don't have to vote for 10 of them if you don't want to. Main villains only! There will be a future list for side villains like Gilgamesh.

The Villains:

Garland
The Emperor
Cloud of Darkness
Zemus
Exdeath
Kefka Palazzo
Sephiroth
Ultimecia
Kuja
Seymour Guado
Shuyin
Vayne
Orphan
Caius Ballad

Fan Favorites: If there's a main villain not on the list that you want to vote for (from say the Tactics series, which I have no experience with), feel free to add them.

I'll post my own answer to the question later on.
