Top 10 Avengers Enemies

We love them because they’re bad! Welcome to and today we’ll be counting down our picks for the top 10 Avengers enemies.

For this list, we’re reviewing Marvel villains that have prominently squared off against the Avengers. These enemies are dastardly, conniving, and just downright evil!

#10: Taskmaster (Tony Masters)

Taskmaster debuted in the 1980 “Avengers” #195. Originally a S.H.I.E.L.D. agent known as Tony Masters, he obtained photographic reflexes during one of his last missions, allowing him to replicate and predict the fighting styles of any enemy combatant. Taskmaster then went on to create a special training school for villains and henchmen, something which put him directly at odds with the Avengers.

#9: Korvac (Michael Korvac)

Korvac started life as a vengeful computer technician from alternate universe in the distant future. After a series of events, Korvac betrayed all of mankind to a legion of aliens, obtained the Power Cosmic through downloading Galactus’ knowledge, and became a god-like powerhouse that wanted to reshape the earth in his image. Korvac was only defeated because after the combined efforts of not only the Avengers, but the Guardians of the Galaxy as well.

#8: Baron Helmut Zemo

First appearing in 1973’s “Captain America” #168, Helmut is the thirteenth Baron Zemo and is the son of the son of the deceased Nazi scientist Baron Heinrich Zemo. Like his father before him, Helmut often fights Captain America and, also like his father, he’s led a group of evildoers calling themselves the Masters of Evil. Despite the horrible accidents that he and his father both suffered as a result of the super strong Adhesive-X, both generations of Zemo frequently try to use the fickle substance to stick it to the Avengers and anyone else who’s tried to stop them.

#7: Doctor Doom (Victor von Doom)

Doctor Doom originated in the 1962 “Fantastic Four” #5. Born to a poor gypsy family in the fictional country of Latveria, Victor von Doom was inherently smart and became a leading scientist, though an accident left him in bad physical shape, hence why he dons an armored suit. Turning to evil, Doctor Doom organized a coup d’etat against his country’s leader and declared himself king. As such, he often hatches his evil schemes while working out of his menacing-looking castle. Though he mostly butts heads with the Fantastic 4, Doctor Doom famously fought the Avengers after he unleashed the deadly Venom Virus on New York City.

#6: Kree

A race of violent, efficiently organized warriors with advanced technology, the Kree made their first appearance in 1967’s Fantastic 4 #65. They possess a massive intergalactic empire and are frequently led by Ronan the Accuser. While the Kree are long-time enemies of the Skrulls, their interstellar skirmishes have also pitted them against the Avengers. Although Captain Marvel, who later became an Avenger ,was a Kree himself, the rest of his race did not share in his change of heart.

#5: Skrulls

The Skrulls were introduced as a menacing alien race in the 1962 “Fantastic Four” #2. These green humanoids hail from the Andromeda Galaxy, have warrior-like tendencies, and possess the oldest intergalactic empire. Long-time enemies of the Kree, they are frequently at war throughout the universe, so it should no surprise that the Skrulls have tried to invade earth… which has brought them face-to-face with the Avengers on more than one occasion.

#4: Kang the Conqueror (Nathaniel Richards)

Kang debuted in the 1964 “Avengers” #8. He hails from the 30th century of another Earth in the multiverse, although through numerous adventures throughout space and time he’s created multiple, divergent versions of himself. But, regardless of which Kang you’ve got on hand, he’s conquered countries, planets, and basically time. And, no matter what point in history he sets up shop in, it’s pretty much guaranteed that there’s a team of mighty hero’s on hand to stop him.

#3: Thanos

Making his debut in Iron Man #55, Thanos is an intergalactic tyrant who’s ultimate goal is to win the affections of death herself. Nothing gets in Thanos’ way and he’s not afraid to commit genocide to achieve his goals, even against his own kind! He has been famously equipped with the Infinity Gauntlet, a glove that he created to house the 6 infinity gems gems, which allows him to wield inconceivable powers.

#2: Ultron

After a fair amount of misdirection, it was revealed that Ultron was a robot created by Dr. Hank Pym, the alter-ego of Ant-Man. Originally a benevolent creation that mirrored the intelligence of his creator, Ultron became sentient and improved upon himself by making militaristic modifications. After developing a rather unhealthy Oedipus complex towards Pym, Ultron turned his sights to the destruction of humanity. While his legacy has been forever tainted by his genocidal tendencies, one of the few good things he did was create Vision, who would eventually join the Avengers.

Before we get to our number one Avengers enemy, let’s review some honorable mentions:


The Collector (Taneleer Tivan)

The Mandarin

Count Nefaria (Luchino Nefaria)

#1: Loki

This God of Mischief was introduced in 1949, though the version that most fans are familiar with wasn’t established until 1962 in the first “Journey into Mystery.” In the 1963 “Avengers” #1, Loki inadvertently created the Avengers by tricking the Hulk to wreak havoc on a railroad, causing his brother Thor as well as Iron Man, Ant-Man, and the Wasp to respond. Realizing that Loki masterminded this, the group unified to form the Avengers and defeated Loki. By being not only the original Avenger’s foe but also the very reason for their inception, Loki is an easy pick for #1.
