User blog comment:Ironman444/Apocalypse,Ultron,Thanos who is the ultimate villain among these three/@comment-5473242-20130310050543

I would have to say Thanos, He killed half of the Marvel Universe. While Who is second is a little more for me. I like more ultron, He is a progam,he has backups so he cannot be defeat and he have just conquer the earth
