15 Strongest MCU Villains, Ranked By Threat Level

The Marvel Cinematic Universe relies just as heavily on its villains to succeed as it does the heroes, dreaming up some terrifyingly strong threats for The Avengers and company to take down. The MCU would truly be nothing without its powerful villains, which push the boundaries of how powerful an antagonist in a comic book film can be while still keeping the action somewhat grounded. Even if many Marvel villains have been disappointing, the series has gotten away with some profoundly powerful antagonists over the years.

The villains of the MCU vary wildly in terms of raw power. As the MCU timeline progressed, the series became more and more comfortable introducing powerful magic users, aliens whose threat spans the entire galaxy, and even primordial beings that have existed since the dawn of time. Whether they’re an alien despot, an interdimensional warlord, or a literal god, Marvel’s villains come with some terrifying threat levels of varying intensity.

Ultron

Avengers: Age of Ultron

It says a lot about the average power levels of the Marvel Cinematic Universe’s villains that a foe as terrifying as Ultron is ranked so low. Ultron is the brainchild of Tony Stark and Bruce Banner, and artificial intelligence that was meant to bring piece to the planet and protect it from alien threats by acting as “a suit of armor around the world“. Unfortunately, soon after activating, Ultron decided that “peace” and human life were mutually exclusive, deciding to do everything in his power to wipe the human race off the face of the planet.

Ultron very nearly succeeds in his planet-smashing goal, devastating an entire country with his plans to turn one of their cities into a meteor. His digital consciousness ensures that he can stay in the fight as long as at least one of his thralls or robotic creations is alive, each of which being a powerful drone rivaling an Iron Man suit in capability. Still, Ultron could ultimately be defeated by physical means, and though he left lasting damage in the form of the Sokovia Accords, he certainly underestimated his opponents.

Namor

Black Panther: Wakanda Forever

Compared to Ultron, Namor is a more consistently successful threat that is still an active presence in the MCU. Namor is the product of ancient colonialism of his old Mesoamerican culture at the hands of the Spanish, growing into a powerful mutant. His enhanced strength and durability, flight thanks to his winged ankles, and centuries of combat experience make him a terrifying foe on his own. But Namor also wields strength as the ruler of the Talokan underwater civilization, which has access to their own deposit of Vibranium.

Talokan is the only nation on Earth that can rival Wakanda’s technological prowess thanks to its independent Vibranium stores, and its unique undersea location comes with its own specialized advantages. Namor succeeds at dealing a crushing blow to Wakanda, killing Queen Ramonda, and comes close to besting the new Black Panther in single combat. While Namor’s political power as the ruler of the ocean isn’t to be underestimated, he is still bested by a relatively inexperienced opponent.

Agatha Harkness

WandaVision

Agatha Harkness in the 1700s in Agatha All Along

Less of an overt world-ending threat and more of an insidious planner content to sit in the background, Agatha Harkness is one of the Marvel Cinematic Universe’s most dangerous magic-users. Born a witch, Agatha has the power to absorb magical energy from other beings, taking their power for herself and adding their life force to her own. By meticulously killing entire covens of witches, Agatha has been able to expand her life to be centuries long, biding her time accumulating ever more magical power.

Agatha’s draining powers are capable of killing people even accidentally, making her a deadly foe for anyone to go up against. In What If…? season 3, a variation of her even reaches Celestial heights of power, stealing energy from the likes of Arishem the Judge to become an all-powerful being. The main timeline Agatha bites off more than she can chew, however, though it takes the efforts of the personification of Death herself to finally take her down.

12

Ronan The Accuser

Guardians of the Galaxy

Lee Pace as Ronan the Accuser in Guardians of the Galaxy

Even if he might not be the flashiest villain around, Ronan the Accuser isn’t to be underestimated when pitted agains the wider range of MCU villains. The zealous Kree warlord on a quest to “cleanse” the universe is recognizable by his powerful gavel and armor inspired by a judge’s robes. He’s threatening enough as a powerful alien tyrant, but things really begin to get serious when he harnesses the strength of the Power Stone.

Brimming with the Infinity Stone’s power, Ronan’s strength and durability goes through the roof. He’s able to survive a direct hit from a planet-busting cannon and being run over by a spaceship, and his new empowered gavel is capable of dismantling the defenses of an entire planet with a single touch. Even if his powered-up state doesn’t last long, if it wasn’t for Star-Lord’s quick thinking and Kevin Bacon’s Footloose, Ronan very well may have already demolished the entire galaxy.

11

Gorr The God-Butcher

Thor: Love and Thunder

Gorr the God Butcher grimacing in Thor Love and Thunder

Few MCU villains were as wasted as Gorr the God-Butcher was in Thor: Love and Thunder. Played by Christian Bale, Gorr was once a simple alien eking out a miserable existence on an inhospitable planet, losing his daughter to a brutal drought. When his prayers go unanswered, Gorr ends up bonding with the mysterious All-Black Necrosword, a semi-conscious weapon of profane power that he uses to go on a god-slaying rampage.

Gorr is indeed able to slay multiple gods across the universe, being granted supreme strength and an eerie control over shadows by the evil blade. He’s almost successful in his goal to wish all gods into extinction, reaching the fabled Eternity, but Thor is able to appeal to his humanity at the last minute and get him to wish for his daughter’s life back instead. Gorr is ultimately defeated, but he nearly brings pantheons of gods across the MCU to their knees with his reign of terror.

10

Ego

Guardians of the Galaxy Vol. 2

Kurt Russell as Ego with part of his face missing in Guardians of the Galaxy Vol. 2

According to Ego himself, the main villain of Guardians of the Galaxy Vol. 2 is an ancient presence that has been alive since time immemorial. True to his name, Ego is a living planet whose latent Celestial energy allows him to totally construct and control matter around him, creating biological vessels and entire wondrous landscapes. More insidiously, Ego attempts to weaponize a child inheriting his Celestial powers in order to use them as a battery, allowing him to implant buds of himself across the galaxy that could reforge all of creation in his image.

Ego is certainly one of the most esoteric and horrifying threats to the galaxy the MCU has ever seen. The thought that he came very close to re-shaping the entire cosmos to his liking is a frightening one indeed, and as a literal living planet, Ego is no easy foe to truly defeat. However, his key weak point at the center of his mass is able to be destroyed by the Guardians of the Galaxy with a powerful bomb. Without Star-Lord’s own Celestial heritage cooperating, Ego is little more than a single planet that can be easily avoided.

Kang The Conqueror

Ant-Man and the Wasp: Quantumania

Kang the Conqueror in his purple and green armor in Ant-Man and the Wasp Quantumania

Poor Kang has had a rough go of it as the Marvel Cinematic Universe’s next multi-movie threat that would require the Avengers to once again assemble. Before he was replaced by Doctor Doom as the MCU’s latest big bad, Kang was hyped up to be an esoteric threat to the entire multiverse in projects like Loki and Ant-Man and the Wasp: Quantumania. What makes Kang so deadly is the fact that there is a legion of his variants working in unison to conquer all of creation, not content at just a single universe.

The Kang encountered in Ant-Man and the Wasp: Quantumania is the original conqueror who sparked the Multiversal War, armed with dazzlingly futuristic technology and legions of loyal soldiers. However, he is still a human at the end of the day who is bested by Ant-Man, though his legions of variants currently controlling the majority of the multiverse might not be so simple to defeat. The dramatic gulf in threat levels between different Kang variants averages him out in the middle of the pack, his actual on-screen strength not matching his supposed tyrannical past.

Ikaris

Eternals

Ikaris sad about Tiamut's death in Eternals

The true gut-punch of Eternals was the reveal that not only was one of the Eternals not on the side of humanity, but it was one of their most powerful members. Like the other Eternals, Ikaris is an ancient being placed on Earth millennia ago by the Celestials in order to protect the sentient life there from the scourge of the Deviants. Unlike his brethren, Ikaris was privy to the Celestial’s true goal of raising Tiamat from the Earth via the absorbed consciousness of humanity, willingly complicit in such a grievous act of genocide.

Ikaris is easily the strongest of the Eternals, boasting super-speed, durability, strength, flight, and eye-lasers reminiscent of Superman’s power set. It takes the combined powers of multiple other strong Eternals in order to hold him off, though they aren’t able (or willing) to kill him. Ikaris may be undoubtedly powerful, but it was his own guilty conscience that ultimately served as his own undoing.

Cassandra Nova

Deadpool & Wolverine

Cassandra Nova with Alioth in Deadpool & Wolverine

Existing outside the flow of normal time, Cassandra Nova is the undisputed ruler of the TVA’s Void, where all pruned people and objects go to meet their fate at the hands of the ravenous monster Alioth. However, Cassandra is powerful enough to not only survive, but thrive in this bizarre landscape, becoming a powerful warlord thanks to her terrifying powers. The mutant twin sister of Charles Xavier (or at least, a variant of him), Cassandra Nova has mind-boggling mutant powers on the same level as her brother, perhaps even stronger.

Cassandra Nova boasts telekinesis powerful enough to flay a man in an instant, and laughs off any conventional attacks with overwhelming psychic power. Her ability to read minds in a gruesome manner, regenerate from wounds, phase through objects and teleport gives her a terrifying portfolio of strength few can match. However, any psionic-nullifying helmet like Magneto’s or Juggernaut’s can instantly put a stop to her powers, making her an immensely dangerous Omega-level mutant with one glaring weakness.

Scarlet Witch

Doctor Strange in the Multiverse of Madness

Wanda Maximoff fully becoming the Scarlet Witch in WandaVision

Few characters have had as tumultuous an experience in the MCU as Scarlet Witch’s personal journey. Flip-flopping back and forth between hero and villain multiple times, by the time Scarlet Witch is the major antagonist of a single film, she’s become a potent reality-warping threat thanks to her latent chaos magic. Wanda Maximoff was born to this power, though it was activated and enhanced by exposure to an Infinity Stone, granting her telekinesis and mental manipulation that eventually graduated into full-on reality-altering power.

In Doctor Strange in the Multiverse of Madness, Scarlet Witch is a threat that can only really be ran away from, not faced head on. She effortlessly dismantles variants of some of the MCU’s most powerful characters in her fight with the Illuminati. It’s only through appealing to Scarlet Witch’s humanity that Doctor Strange and America Chavez are able to defeat her, causing her to destroy Mount Wungadore and take her own life. If it wasn’t for this quick thinking, Wanda could’ve very easily succeeded in her original goals and then some.

5

Hela

Thor: Ragnarok

Hela stops Mjolnir in Thor: Ragnarok.

It’s hard to beat Hela’s introduction in Thor: Ragnarok as a first villainous scene, immediately clarifying that the film’s antagonist will be a devastatingly strong threat. The secret eldest child of Odin and a ruthless conqueror, Hela helped the All Father conquer the nine realms and unite them under a single empire, earning herself the title of the Goddess of Death. Her bloodthirsty appetite caused Odin to seal her away in shame after wanting to turn a more peaceful leaf for Asgard, but she returned upon his death.

Shattering Mjölnir as easily as crumpling up a ball of paper in her opening battle, Hela’s jaw-dropping power is instantly conveyed. She’s able to make mincemeat out of Asgard’s strongest soldiers, utilizing her devastating blades to a deadly degree of prowess, even cutting out Thor’s eye. With her army of the dead, Hela is an unstoppable force that even the mighty Thor couldn’t overcome, relying on another, even more powerful villain to defeat her instead.

4

Thanos

Avengers: Infinity War

Thanos in the Soul Realm in Avengers Infinity War

Thanos needs little introduction as one of the most devastating villainous forces the Marvel Cinematic Universe has ever introduced. An alien tyrant from the planet Titan obsessed with curbing overpopulation with the random genocide of half the universe, Thanos is already an absurdly strong foe before he even gets his hands on any Infinity Stones, handling The Hulk like a toddler in single combat. Not only that, his loyal legions of soldiers, outriders, and Black Order members allow him a degree of influence rarely matched by other galactic players.

When he does finally get all six stones, Thanos becomes even more unstoppable, actually succeeding in his goal of wiping out half of all life. It’s only through time travel that Thanos’ actions are able to be undone, and even then, his younger self very nearly enacts an even more terrifying future for the MCU. Still, the usage of Infinity Stones as paperweights at the TVA diminishes his threat in the multiversal scheme of things, and Thanos with two Infinity Stones is very nearly defeated by the Guardians of the Galaxy, Doctor Strange, Iron Man and Spider-Man.

3

Surtur

Thor: Ragnarok

Hulk wanting to fight Surtur in Thor Ragnarok

Surtur may not appear for too long in the Marvel Cinematic Universe, but he’s one of the few powerful villains to have directly proven himself stronger than another. An ancient fire giant from the realm known as Muspelheim, Surtur was once defeated by Odin long ago, separated from his power source, the Eternal Flame, and banished to his home realm. Thor is able to easily defeat Surtur in the beginning of Thor: Ragnarok in this weakened state, but things are far different once Surtur gets his hands on the Eternal Flame.

Once reunited with his old flame, Surtur rises to gigantic heights, brimming with otherworldly flame and laying waste to Asgard, fulfilling the ancient prophecy of Ragnarok. Even Hela isn’t able to stop him at this point, seemingly perishing in an attempt to keep Surtur from destroying her newly-conquered kingdom. Though Surtur ends up killing himself in the effort, as well, there’s no telling what destruction he could’ve caused should his goals have been more ambitious than simply destroying the nation of his former enemy.

2

Arishem The Judge

Eternals

Arishem in space in What If...? season 3 episode 2

As an overarching villain, it’s hard to top the mind-boggling power of Arishem the Judge. The ostensible leader of the Marvel Cinematic Universe’s Celestials, Arishem is an ancient deity that has existed nearly as long as creation itself, the Prime Celestial ruling over all other cosmic beings and enacting his own universal laws. Arishem is credited with creating the first sun, beginning the processes that would allow for life to develop, as well as having a hand in the birth of the Deviants, Eternals, and even other Celestials.

The Eternals truly had no chance of realistically stopping Arishem in a fight, though they were able to successfully divert the Emergence on Earth that would’ve resulted in the birth of Tiamut. If he wanted to, Arishem could easily wipe out all life on the planet, though he thankfully chose to at least reserve judgment to hear what Sersi, Kingo, and Phastos had to say about humanity as a whole. It’s hard to top an ancient cosmic entity like Arishem the Judge as a powerful villain.

Death

Agatha All Along

Death in a green cloak in the 1700s in Agatha All Along

Arishem the Judge might be an immensely powerful being, but even he is still beneath an entity so ancient that she represents a fundamental concept, Lady Death herself. Death first appeared at the very start of the universe alongside her siblings, Entropy, Eternity, and Infinity. Death is ancient and powerful enough to be blessed with a statue alongside her siblings at the gates of Eternity in Thor: Love and Thunder, owing to her profound influence on the multiverse. Death appeared on Earth hundreds of years ago as the Green Witch Rio Vidal, falling in love with Agatha.

True to her name, Death is simply able to take the life of anyone she wants, though people close to her like Agatha can have an influence on when and where she chooses to ultimately collect the souls promised to her. Death may be perfectly content to play pretend as a mortal being like Rio Vidal, but make no mistake – She is a ruthless and persistent force of the universe that can be reasoned or bargained with, but never stopped outright. It would certainly be a surprise if the MCU ever introduced a villain capable of outdoing Death.
