I almost negged you for mentioning Zemo

?But then you acknowledged Magneto could and should be goat villian if done right

Smh at folks couldn't wait to try to shoehorn one of these marvel villians into the top spot,its the Joker and Bane at one and 2 for me.
They won't get the proper respect just because Marvel films are more cartoonish and fantastical.
But Joker and Bane were both entertaining,had better quotables than Thanos more importantly. And in terms of classic scenes I just think they had more standout moments. How did you forget the plane and sewer scene from Bane so quickly smh?The Joker car chase scene,bank scene,hopsital scene,too many to name. Also if your going to mention Zemo,Winter Soldier needs some love too. Every scene where he was doing Winter Soldier shyt is a god damn classic. I know he sucks as Bucky,but the Winter Soldier is one of Marvels best villians hands down,and doesn't get the respect!
edit-Might have to put Winter Soldier over Killmonger now that I'm thinking about it
