Veiger has the voice and the skin. He's the super villain no one takes seriously.

There's no way Malzahar isn't just some pawn to be used by a greater Void monster. Void creatures probably see humans as a "scourge upon the world" or something like that. No way Malzahar has more standing then Cho'gath when it comes to the hierarchy of the Void. And yes, the Void are the evil ones that want to eat all of us.

Mordekeiser as the shadow isles seem more like a threat to existence (thus a better chance to be a greater over arching villain) then Swain (aka Noxus), which really is just a different style of living then Demancia, and is not inherently evil per-say.

lux because her laugh

I think it can be the hole Black Rose, including Coteau, and with Katarine and Talon as assasins inside of the league and with LeBlanc and Swain to investigate, I think the ruler of them would be teh General Du Coteau. Cassiopeia could be, too.

Whenever Veigar enters the fields of justice heroes within a mile feel a dark presence within their soul.

How come nobody here brought up Brand? I wouldn't say he is THE LoL villain, but hey he is one of those men who want to watch the world burn. But anyways. THE Villain would have to be Swain. While the others are big maybe even bigger threats they're are not the constant villain. Swain and Noxus are the main villains. Think comics. Batman has The Joker, Supes has Luthor Spider-Man has Green Goblin. Sure lots of other villains come and go (Voidlings like Cho, Herc from the Shadow Isles, Viegar the comedy relief villain etc etc) but the main threat to the "good guys" who to me is Demacia is Noxus who is now led by Swain. Just my opinion anyways thinking from a Demacia/Jarvan viewpoint lol.

I think amumu would be the best. He has such a dark past no one knows about. Imagine if one day he realized his cause for sadness and turned all his pain and hurt into anger. That, I wouldn't want to **** with.

Soraka Obviously.
