To be ranked as some of the best villains in marvel comics they have to be dastardly, cool, clever, or just plain evil. And the marvel universe is filled with plenty of villains that fit the bill. But only a select few of the villains in marvel comics are the baddest of the bad. Not all the villains in marvel comics could hold the distinction of the absolute best, but these are among the ones that can.
First up we have the Green Goblin, Norman Osborn. He may not be the most powerful of all the villains in marvel comics, but he's definitely one of the vilest. Terrorizing Spider-Man until Osborn's death, and then terrorizing him again when he came back from the dead, Osborn is vicious, depraved and unpredictable. And now that he sits in a seat of power over the entire marvel universe that unpredictability and his psychopathic tendencies just shot him up to the top of the list of the greatest villains in marvel comics.
Next we have the Kingpin, Wilson Fisk. All the man boasts is enormous girth, intense strength and a ton of money, which adds many minions to his call. A thorn in the sides of the likes of Spider-Man and Daredevil, the Kingpin was at one time one of the most ruthless villains in marvel comics. He had no regard for life and didn't care who he hurt. He was on top of the world and had the world fooled for a long time while he acted as the head of the criminal underworld. Had Daredevil not finally taken the big man down he'd still be sitting on his empire, an empire worthy of one of the greatest villains in marvel comics.
Then there's Ultron, the creation of Henry Pym that went on to terrorize and nearly destroy the Avengers on more than one occasion. This super-intelligent and possibly sentient robot is one of the greatest villains in marvel comics simply because he's not human. He doesn't have a heart or a mind, and thus everything he does is cold, calculated and despicable. His sole goal is to rid the world of the Avengers and anyone else who stands in his way.
Of all the villains in marvel comics, Apocalypse is potentially the greatest threat. He's a seemingly immortal mutant that in every possible future of the marvel universe thus far he has ruled and reigned eventually. If the Age of Apocalypse story line showed us anything it showed us just how bad this mutant supremacist is.
And finally there's Magneto, the Master of Magnetism, and no list of the greatest villains in marvel comics would be complete without him. What makes Magneto so deadly isn't just his ability to control any kind of metal in existence, including the iron in our blood. But it's the cause that he fights for. He truly believes he is doing the right thing, and when a being with that much power is convinced that he's the savior of his people there's no limit to the lengths of destruction he might go to.
There are other great villains in marvel comics as this is just a few notable standouts. And each and every one of these listed have done much to deserve their place in such a list.
