The 10 Most Iconic Avengers Villains of the 1990s, Ranked by Importance

As a huge Avengers fan, I’ve always been fascinated by the ’90s era. It wasn’t a great time for Marvel overall – they were struggling financially and stories were kind of all over the place. It really felt like the comics might not survive! But, they managed to turn things around by the end of the decade. While a lot of books relied on fancy covers to sell, the Avengers actually had a pretty interesting ride. They went through a few years with a team that wasn’t quite clicking, but they finished the decade strong with some really memorable stories. Those villains, even if they weren’t the biggest names, are still a cool part of the team’s history, in my opinion.

The 1990s brought back some well-known Avengers villains, but also introduced a few characters that modern readers might not recognize, even though they were significant at the time.

10) Lord Templar

I first encountered Lord Templar when reading Avengers Vol. 3 #13 back in 1999, during what felt like a really exciting time for Marvel. Kurt Busiek and George Perez were bringing everything back to normal after the whole Onslaught event, essentially undoing a big reboot and giving us the Avengers we’d all loved for thirty years. But a good story needs a villain, and that’s where Lord Templar came in. He was this incredibly powerful, almost primal force unleashed by the scheming Jonathan Tremont as a kind of test for the newly reformed team. While Tremont was pulling the strings, Templar was the real physical threat – a truly imposing enemy who continued to challenge the Avengers well into the new millennium. I was immediately captivated!

9) Magus

The Magus is a villain who is essentially the future, evil version of Adam Warlock. Created by Jim Starlin in the 1970s, he resurfaced in 1992’s “The Infinity War” and became a major threat to the Avengers. After the Avengers defeated Thanos and the Infinity Gauntlet was taken by Adam Warlock, Warlock split into two beings – himself and the Magus. The Magus then sought ultimate power and created corrupted duplicates of Earth’s greatest heroes, including the Avengers. While incredibly dangerous, threatening all of existence, the Magus isn’t considered one of the Avengers’ greatest foes because the conflict wasn’t solely focused on them; they were just one part of a much larger battle.

8) Proctor

Proctor served as the primary antagonist in “The Gatherers Saga,” a storyline that spanned issues #343-375 of Avengers Vol. 1 (1992-1994), created by Bob Harras, Steve Epting, and Tom Palmer. He was unveiled as an alternate version of Dane Whitman, the Black Knight, and led the Gatherers – a group of survivors from different universes whose Sersi had gone insane. Proctor aimed to eliminate all versions of Sersi across the multiverse, including the one on Earth-616, and also targeted the Avengers. He was a significant threat in the early to mid-1990s, and notably, he even had a captured Watcher assisting him. Proctor was a powerful villain who loomed over one of the Avengers’ key members during that era.

7) Thanos

Thanos first rose to prominence as a major villain for the Avengers in the 1990s, but his threat extended far beyond Earth’s heroes – he endangered the entire universe. Created in 1973 by Jim Starlin, Thanos reached peak popularity with the 1991 storyline “The Infinity Gauntlet,” co-created by Starlin, George Perez, and Ron Lim. In this story, Thanos acquired the Infinity Gauntlet and used it to eliminate half of all life, including many superheroes. He continued to be a central figure in the follow-up stories “Infinity War” (1992) and “Infinity Crusade” (1993), which also involved the Avengers. While the Avengers were key players in fighting him, Thanos was a universal danger, and many different teams joined forces to try and defeat him.

6) Immortus

Immortus is an incredibly powerful, future version of Kang the Conqueror, a villain who has plagued the Avengers since the 1960s. He became a major figure in the late 1990s thanks to the acclaimed miniseries Avengers Forever, where it was revealed he works for powerful beings called the Time-Keepers. Immortus attempted to prevent humanity from becoming a galactic power by sending an agent to kill Rick Jones. Using a powerful artifact called the Forever Crystal, he secretly manipulated events throughout Avengers history, making him the mastermind behind much of their time-traveling conflicts. Avengers Forever is considered one of the best Avengers stories of the 90s, and it highlights Immortus’s significance. However, his plans were complicated when Kang rebelled against him, setting the stage for future conflicts.

5) Morgan le Fay

The Avengers’ first major challenge after their relaunch in 1998’s Avengers Vol. 3 #1-3 was Morgan le Fay. This storyline, called “Morgan Conquest,” kicked off the “Heroes Return” era and re-established the team within the main Marvel timeline. Morgan le Fay, a powerful sorceress from Arthurian legend and sister to King Arthur, abducted Scarlet Witch and combined her reality-altering abilities with elven magic and the Twilight Sword. This resulted in the creation of an alternate Earth (Earth-398), where the Avengers were forced to serve as her armored warriors. As a villain capable of warping reality, Morgan le Fay ultimately restored the team to the present, but left Scarlet Witch with dangerously amplified powers, setting the stage for future storylines.

4) Iron Man

As a longtime Avengers fan, I still remember how shocked everyone was by “The Crossing” storyline. It completely changed how I saw Iron Man! For about 25 issues, from ’95 to ’96, it was revealed that Tony Stark had been a double agent the whole time, secretly working for Immortus – who was actually Kang in disguise. It was awful seeing Iron Man kill Yellowjacket and Marilla just to cover his tracks. The Avengers had to bring in a younger Tony Stark from another reality to try and stop him, and ultimately, the older Tony sacrificed himself to save the team. It was such a bold move to have a founding member turn out to be a villain, and it remains one of the most controversial stories the Avengers have ever done. It really divided fans, and honestly, it still feels crazy to think about!

3) Ultron

Ultron has been a recurring enemy of the Avengers ever since he first appeared in 1968. A key characteristic of Ultron is his ability to constantly rebuild himself after being defeated. One of his most famous stories, “Ultron Unlimited” (1999), is considered a high point for the character. In this storyline, Ultron completely destroyed the fictional country of Slorenia, wiping out its entire population in a matter of hours. This event served as inspiration for the destruction of Sokovia in the movie Avengers: Age of Ultron. The 1990s generally portrayed Ultron as particularly menacing, and it also highlighted the complex relationship between the villain and his creator, Hank Pym.

2) Onslaught

Onslaught is a major Marvel Comics villain, far more powerful than a typical Avengers foe. He originated from the combined psychic trauma and rage of Professor X and Magneto after their minds were linked. This created a separate entity with the immense powers of both mutants. In a huge storyline called “Onslaught Saga,” the creature shockingly defeated and killed the Avengers, the Fantastic Four, and even a portion of the Hulk. This is one of the few times the Avengers truly lost – and many of them died. Thankfully, Franklin Richards rescued them, trapping them in a separate dimension for a year. However, the Avengers’ defeat at the hands of Onslaught made him one of their most significant and memorable villains of the 1990s.

1) Kang

Throughout the 1990s, Kang was the Avengers’ primary adversary. Initially, the comics established that Kang, not Immortus, was the force behind the events of “The Crossing” – although this was later revised. Beyond that, Kang featured prominently in stories like “Citizen Kang” (1992), where the Avengers fought his city, Chronopolis, and his army, the Anachronauts. He led the Council of Cross-Time Kangs, a storyline that continued in “The Terminatrix Objective” (1993), and his complex relationship with Ravonna was explored throughout the decade. He even appeared as an ally in Avengers Forever (1998-99), teaming up with a younger version of himself to fight Immortus. While his most famous story, “Kang Dynasty,” came later, Kang consistently posed a significant threat to the Avengers throughout the entire 1990s.
