Due to there being a 3-way tie for 5th place in the poll, it took awhile to actually decide a top 5. But we finally have it sorted out. So without further ado, let’s get started on the countdown of the greatest collection of villains, as voted on by you.
We begin our journey with Marvel’s primary supergroup:
Earth’s Mightiest Heroes don’t have quite as lenghty a list of major adversaries as some of the other protagonists in the poll, but the level of a threat that their villains typically pose is quite high. Which makes sense considering that the whole point of The Avengers is to deal with threats that no hero could handle individually.
Atop their list would be Ultron, an android bent on the annhilation of the human race. Created by Hank Pym, and given his brain patterns, Ultron is as brilliant as he is powerful. Equipped with an army of drones that all share a hive mind, a myriad of laser weapons, the ability to control and/or transfer his memory and personality into other mechanical devices remotely, and an exoskeleton made of the virtually indestructible metal adamantium, it’s not difficult to see why he has remained such a constant thorn in the side of The Avengers.
Not far behind Ultron on the list of Avengers baddies would be the maniacal Kang the Conqueror. Using time-traveling technology from the 30th Century, Kang (who is a decendant of Mr. Fantastic, with connections to Dr. Doom as well) travels from one time period to the next attempting to establish himself as ruler. Even though he possesses no actual superpowers, his genius-level intellect, his knowledge and skills in physics and engineering, and armor and technology from far more scientifically advanced times, Kang has been a major villain for several of Marvel’s heroes, but most notably The Avengers.
Essentially the antithesis of The Avengers would be the Masters of Evil, a team of major, and sometimes not so major, villains banded together to destroy their heroic counterpart. While the team has gone through several incarnations, it is usually lead by prominent Captain America big bad Baron Zemo. The first villains to really bring the fight to The Avengers instead of the other way around, they have attacked The Avengers Mansion on several occassions.
It would be very easy to dismiss The Taskmaster as a major player, but that would be a mistake. While he has no superpowers outside of “photographic reflexes”, the ability to absorb, recall, and replicate knowledge and information instantaneously. This allows him to mimic and predict the movements and tendencies of any hero he sees. His in-depth observation of The Avengers has allowed him to replicate the hand-to-hand combat skills and athleticism of Black Panther, Daredevil, Iron Fist, and Captain America, as well as Cap’s abilities with his shield, the marksmanship of Hawkeye and Black Widow, and the swordsmanship of the Black Knight. It may not seem like much, but he has proven time and time again to be a threat worthy of Earth’s Mightiest Heroes.
While he is most notably a villain of Thor, Loki has been a significant adversary of The Avengers as well. In fact he inadvertantly lead to the creation of the team. He had used The Hulk as a puppet to try to get revenge on Thor. Eventually his deceit is discovered and Rick Jones, Hulk’s sometimes sidekick, reaches out to Iron Man, Ant-Man, and The Wasp to assist them in defeating Loki. From that moment on, he has remained a fly in the ointment of The Avengers.
Arguably the greatest single threat to the Marvel Universe was Thanos when he wielded the Infinity Gauntlet. Granted virtual omnipotence from the Gauntlet, heroes (and even a few villains) from across the galaxy joined forces lead by The Avengers in an attempt to stop Thanos from destroying all life in the universe. Even after his defeat in the Infinity War, The Avengers have continued to battle The Mad Titan over his obsession with death.
