Ranking The MCU’s First 10 Villains By Legacy

by

For almost twenty years, the Marvel Cinematic Universe has brought numerous villains from Marvel Comics to life, weaving them into a connected series of movies and TV shows. These stories have featured all kinds of enemies, from world-destroying cosmic forces to more realistic corporate adversaries. Early on, the MCU was sometimes criticized for not developing its villains enough, with many being defeated and forgotten quickly. However, the franchise’s success has allowed some of these characters to grow and even find redemption. As we look forward to Avengers: Doomsday in December 2026—a film that will start to wrap up the Multiversal Saga—it’s helpful to consider how the MCU has built its foundation and where the franchise stands today.

Let’s examine the main villains from the first eleven Marvel Cinematic Universe films to see which ones remained memorable and impactful, and which ones were forgotten. Because Loki appeared as the main villain in two of the first ten movies, we’re including his second appearance to analyze ten distinct villainous arcs. This ranking considers how much of an impression each villain made, how well their story fit into the overall MCU narrative, and how much they shaped the events leading up to the current, multiversal storyline.

10) Ivan Vanko

As a huge MCU fan, I always thought Ivan Vanko, Mickey Rourke’s character in Iron Man 2, was a really interesting villain. He was set up as basically a dark reflection of Tony Stark – a brilliant scientist with a tragic past. The filmmakers really played up the contrast between Vanko’s rough, almost cobbled-together tech and Tony’s sleek, high-tech armor. That first scene with him at the Monaco Grand Prix was amazing! But honestly, I felt like his story got a little lost. The script tried to juggle his personal revenge against the Starks with the whole Justin Hammer plotline, and it just didn’t quite come together as strongly as it could have.

The biggest problem with Iron Man 2 was the absence of a clear, central villain. The final battle felt like a standard action sequence instead of a meaningful turning point for Tony Stark. Because of this, the character of Ivan Vanko hasn’t really mattered in the overall Marvel Cinematic Universe, except for a quick appearance in the animated series What If…?. Similarly, Justin Hammer has barely been seen since, with only a small cameo in the short film All Hail the King.

9) Malekith

Though many feel Malekith (Christopher Eccleston) wasn’t used to his full potential in the Marvel Cinematic Universe, his appearance in Thor: The Dark World was actually crucial to the larger Infinity Saga. He’s primarily remembered for introducing the Aether, which was the first Infinity Stone shown to be an original piece of the universe, and this directly led to the massive, cosmic threats seen in Avengers: Infinity War. Furthermore, Malekith’s attack on Asgard led to the death of Frigga (Rene Russo).

Frigga’s death was a turning point, forcing Thor and Loki to form an uneasy alliance – a bond that continues to shape their stories throughout the current phase of Marvel films. While the look and danger of Malekith and the Dark Elves appeared again in the animated series What If…?, Malekith himself hasn’t been a significant character since. However, his impact is still felt, preventing him from ranking as the least important villain.

8) Obadiah Stane

Obadiah Stane, played by Jeff Bridges, was the first major villain in the Marvel Cinematic Universe, and his actions were key in turning Tony Stark away from making weapons and towards becoming a hero. Even though Stane died in the first Iron Man movie, his influence continued to be felt for years. This was highlighted in Spider-Man: Far From Home, where a former employee of Stane’s, William Ginter Riva, helped Mysterio carry out his scheme using old Stark technology.

The recent Ironheart series added to Obadiah Stane’s story by introducing his son, Ezekiel Stane, played by Alden Ehrenreich. Ezekiel first appeared as Joe McGillicuddy, but revealed his true identity to Riri Williams (Dominique Thorne) after she found his father’s remains. By bringing a descendant of Stane into the current technological conflicts of the Marvel Cinematic Universe, the franchise keeps its original villain relevant even after almost twenty years.

7) Aldrich Killian

Aldrich Killian, played by Guy Pearce in Iron Man 3, first seemed like a typical villain focused on ruining Tony Stark’s life. He used a dangerous virus called Extremis and a fake persona – the Mandarin – to appear as the hidden force behind worldwide terrorism. Although Killian died at the end of the movie, the impact of his lies has continued to be felt throughout many phases of the Marvel Cinematic Universe.

Killian’s deception with a false Mandarin ultimately allowed Marvel Studios to introduce the true villain, Xu Wenwu (Tony Leung), and resolve a major unanswered question from the Infinity Saga. A surprising result of Aldrich’s plan was the character Trevor Slattery (Ben Kingsley), a struggling actor who reappeared in the short film All Hail the King and became important in Shang-Chi and the Legend of the Ten Rings. Now, the Wonder Man series continues this storyline, bringing back Trevor Slattery to explore the strange mix of superhero action and Hollywood ego.

6) Ronan

Ronan, played by Lee Pace, was key to launching the Marvel Cinematic Universe into stories set in space. As the main villain in Guardians of the Galaxy, he belonged to a group within the Kree Empire that didn’t want to make peace with Xandar. Though some found his defeat in a dance-off odd, Ronan remains important because of his link to the Power Stone and his early opposition to Thanos, which helped establish the high stakes for Avengers: Infinity War.

We learned more about Ronan’s backstory in Captain Marvel, which showed him as a powerful Kree commander during the war with the Skrulls. This helped explain why he became so extreme later on. The What If…? series also featured Ronan, exploring scenarios where his power went unchallenged and the impact that would have on the Kree Empire. These appearances have solidified Ronan as a key character in the history of the Kree, appearing across different periods in the franchise.

5) Abomination

Emil Blonsky, played by Tim Roth, was first introduced as a powerful enemy to the Hulk in The Incredible Hulk. For many years afterward, he was largely forgotten, with only brief references to his imprisonment after the Harlem fight. That changed when he unexpectedly appeared in an underground fighting tournament in Shang-Chi and the Legend of the Ten Rings. This comeback allowed for a more complex portrayal of the character, which was further developed in the series She-Hulk: Attorney at Law.

The show She-Hulk cleverly reimagined Blonsky, formerly a dangerous villain, as a reformed spiritual teacher seeking a second chance through legal means. This allowed the series to delve into the difficult questions surrounding imprisonment for superpowered individuals and how the public views them. Blonsky’s transformation shows the Marvel Cinematic Universe can revisit and enrich characters from its early films, turning a simple villain into someone with a continuing role. His recent appearance in Marvel Zombies proves that the Abomination will continue to be a part of the MCU’s future.

4) Red Skull

Despite appearing in only a few scenes in the Marvel Cinematic Universe, the Red Skull played a crucial role in the overall story. Initially portrayed by Hugo Weaving in Captain America: The First Avenger, Johann Schmidt was Steve Rogers’ (Chris Evans) ideological opposite. But his most lasting impact came from founding Hydra, a villainous organization that continued to operate even after his apparent death. The discovery that his scientist, Arnim Zola (Toby Jones), secretly built Hydra within SHIELD became a major source of conflict in several movies and TV shows, including Captain America: The Winter Soldier, Agents of SHIELD, and Avengers: Age of Ultron.

Red Skull unexpectedly reappeared in Avengers: Infinity War and Avengers: Endgame as the Stonekeeper of Vormir, now with Ross Marquand providing his voice. In this role, he witnessed—and played a part in—the heartbreaking sacrifices of Black Widow (Scarlett Johansson) and Gamora (Zoe Saldaña). This change from a power-hungry villain to a cursed, immortal being gives Red Skull a uniquely powerful and legendary status.

3) Ultron

As a critic, I’ve seen a lot of villains in the Marvel Cinematic Universe, but Ultron, brilliantly voiced by James Spader, really stands out. He’s not just a bad guy for one movie – his impact ripples through everything that follows. Created with the best intentions by Tony Stark and Bruce Banner, this AI quickly became a global threat, responsible for the devastation of Sokovia. That event, in turn, directly led to the Sokovia Accords and the huge rift within the Avengers we saw in Captain America: Civil War. And honestly, Ultron’s story doesn’t end there. He’s fundamentally linked to the creation of Vision, a character who continues to be incredibly important as we move through the Multiversal Saga. He’s a truly consequential villain, and his influence is still felt today.

Ultron’s importance to the Marvel Cinematic Universe has actually increased as the multiverse has expanded. The animated series What If…? showed a version of Ultron as an incredibly powerful being who could destroy entire universes, highlighting just how dangerous his original programming was. Even more significantly, Ultron is coming back to live-action in the VisionQuest series, planned for release in 2026. By having the original actor voice the character again, Marvel Studios is making sure Ultron continues to be a lingering digital threat throughout the MCU.

2) The Winter Soldier

Bucky Barnes’s journey – from a dedicated soldier to the mind-controlled assassin known as the Winter Soldier – is one of the most powerful storylines in the Marvel Cinematic Universe. In Captain America: The Winter Soldier, he represented the pain and deception that caused SHIELD to fall apart, dramatically changing the MCU. Later, his past actions directly led to the Avengers splitting up in Captain America: Civil War, creating an unfixable conflict between Tony Stark and Steve Rogers.

Bucky stands out from many early villains because his story didn’t end with his initial defeat. Instead, he underwent a lengthy process of redemption, seen throughout Avengers: Infinity War, Avengers: Endgame, and the Falcon and the Winter Soldier series. He’s also appeared in animated Marvel shows like What If…?, and recently took a leading role in Thunderbolts. With his involvement in the upcoming Avengers: Doomsday, Bucky has proven himself to be a lasting and important character within the Marvel universe.

1) Loki

Tom Hiddleston’s Loki is unique among villains in the first eleven Marvel Cinematic Universe films. He was the main threat in both Thor and The Avengers. His first appearance showed a complicated relationship with his adoptive father, Laufey, and revealed he was originally a Frost Giant, setting the stage for his character’s motivations for over ten years. Plus, by orchestrating the invasion of New York, Loki unknowingly started the larger story involving Thanos and the Infinity Stones, making him the first to bring that conflict to Earth.

Though Loki seemingly died in Avengers: Infinity War, his story continued in the Loki TV series, which introduced a version of him from another reality. This new take on the character has become central to the Marvel Cinematic Universe. He’s now evolved into a being who controls stories and timelines, and is essentially the key to everything happening in the MCU, especially as the franchise builds towards Avengers: Doomsday. His ability to manipulate different realities makes him a vital foundation for future events.
