Doctor Doom, but that he is indeed a confirmed variant of Stark, marks the first time the MCU has seen him as a villain. However, Tony has broken bad more than a few times in the comics.

In fact, some would argue that his worst betrayals make him more of a villain than a hero. From his controversial actions in the Civil War to the catastrophic creation of Ultron, Stark's decisions often result in disastrous consequences.

Several of Iron Man’s most iconic moments in the MCU were foreshadowed decades earlier in the iconic 1990s Iron Man: The Animated Series.

It's something that should have been expected from a character whose MCU appearance was based on Elon Musk after all. His willingness to prioritize his vision over the safety of others has led to the fall of many beloved characters, showing how his actions can be more damaging than beneficial.

10 His Heroism is For Ego, Not World Peace

Tony Could End World Hunger, But Chooses Not to

Tony Stark's most obvious betrayal is to the general public, specifically in how he chooses to use his vast fortune. Stark believes fighting global threats in his high-tech armor makes the world safer, but his approach overlooks the root causes of societal issues, such as poverty, hunger, and inequality, making him more of a band-aid than a true problem-solver. Much like his MCU inspiration, Elon Musk, Tony Stark has the resources to end world hunger, cure disabilities, and pioneer renewable energy on a scale that could reshape humanity’s future, but chooses to prioritize profit above all else.

After 17 Years, I’m So Impressed At Where The Original Iron Man Movie Still Sits In The MCU’s Movie Review Rankings

The Marvel Cinematic Universe has released some of the best superhero films of all time, with the first Iron Man ranking shockingly high.

The same cutting-edge nano bots technology he uses to build his suit has the potential to cure cancer, but instead of focusing on the well-being of others, Stark channels these breakthroughs into projects he claims are for the good of humanity, but are really self-serving projects that tend to blow up in his face. While Tony’s fight against supervillains paints him as a hero, it’s important to question the true ethical implications of his wealth. With a net worth estimated at $140 billion, he represents a class of individuals whose fortunes are built on systems that thrive on inequality.

The ethical dilemma becomes clear when we realize that, with such vast resources, he has the potential to enact transformative changes, but instead opts for solutions that elevate his status rather than addressing society’s most pressing needs.

Most individuals fail to realize just how much money that is until you present the cost of problems that money could actually solve. Given that the best estimate for ending world hunger is approximately $30 billion a year, this means Tony could end world hunger for an entire presidential term and still have $20 billion left over. The ethical dilemma becomes clear when we realize that, with such vast resources, he has the potential to enact transformative changes, but instead opts for solutions that elevate his status rather than addressing society’s most pressing needs.

9 Tony Stark’s Implanted Devices

Monitoring the Avengers Without Their Knowledge

Tony Stark’s invasion of his fellow Avengers’ privacy reaches new heights in the Avengers #25 story arc, "Daddy’s Boys". While offering Thor a new Stark-made hammer, Stark reveals that he has placed implants within most of the Avengers, including Thor. enable him to monitor vital signs, including blood sugar levels, brain activity, and even blood alcohol levels. This level of surveillance is a shocking breach of privacy, especially for those who view themselves as part of a close-knit team of equals.

This blatant disregard for privacy creates a rift between Tony and his fellow Avengers, especially when considering the relationship Stark shares with Captain Marvel and Thor, who also battle alcoholism. The ethical violations in this scenario have the potential to break apart friendships and cause irreparable damage. The fact that Stark did this without the permission of his teammates speaks volumes as well. Stark’s willingness to compromise his teammates’ privacy in the name of “safety” reveals a villainous disregard for personal boundaries, underscoring his tendency to overreach with his authority within the team.

8 Tony Stark Convincing Peter Parker to Expose His Identity

The Superhero Registration Act

Tony’s decision to push Peter into exposing his identity underscores a more sinister side of Stark. In the Civil War storyline, Tony makes one of the most controversial decisions in his career by convincing Spidey to reveal his identity to the public. He believes that in doing so, it will allow Peter to function more freely as a hero, positioning it as a necessary sacrifice for the greater good. He pushes Parker past his initial hesitations, all while knowing that the revelation will put Peter's family on the radar of some of the most violent criminals in New York City.

Okay, Spider-Man 4 Actually Has To Explore The Story Of Daredevil: Born Again Now After Its Season 1 Finale

While Daredevil has been relegated to the television side of the Marvel Universe, events from Born Again’s finale must be included in Brand New Day.

At first, Peter agrees, seeing the benefits of Stark’s argument and trusting that it will strengthen their cause. However, the aftermath reveals the true cost of Stark’s persuasion, which puts Peter’s loved ones directly in his super-powered enemies' crosshairs. In the end, Tony's push for Peter to go public was purely to bolster his argument in the broader conflict of the civil war, rather than what was actually best for Peter, making Tony’s role in the decision much more villainous than heroic.

7 The Thorbuster Suit's Brutal Betrayal

Using The Thunder God's Gift Against Him

Tony Stark’s creation of the Thorbuster armor is one of his most brutal betrayals. In Iron Man #64, Stark unveils the Thorbuster suit, powered by an Asgardian crystal Thor himself had gifted to Stark. While Thor’s powers are unparalleled, Stark’s ingenuity allows him to design a suit capable of contending with the Thunder God. Thor trusted Tony with this powerful artifact, believing it would be used for peaceful purposes. Instead, Stark repurposes the crystal, turning it into a weapon meant to counter the god he calls a friend.

This betrayal cuts deep, as Tony not only violates that trust but also weaponizes a gift meant to symbolize their bond, showing a stark disregard for their friendship. By using the crystal in such a reckless manner, Tony crosses a line that transcends heroism into arrogance. The betrayal is all the more painful because it shows Stark’s willingness to exploit their friendship for his own sense of control. The crystal, once a symbol of trust and camaraderie, becomes a tool of war, turning Thor’s goodwill into a tragic reflection of Tony’s own hubris.

6 Turning Hulk Into A Monster

Gamma Radiation Has Nothing On What Tony Did To Banner

Tony Stark’s treatment of the Hulk has done more to fuel the monster within than any external force could. Instead of seeing the Hulk as an Avenger with immense potential, Tony viewed him solely as a danger that needed to be contained. By creating the Hulkbuster suit, Stark reframed Hulk as an uncontrollable threat rather than the hero he was. This not only alienated Bruce Banner but also further fueled Hulk’s rage, emphasizing the idea that he was a mindless force of destruction rather than a member of Earth’s mightiest heroes.

Hulk's New Costume Makes No Sense... And It's Still His Coolest Redesign Yet

Despite the impracticability of the Hulk's latest redesign, it may be one of his best yet, for one simple reason.

1

Tony’s phobic tendencies towards Bruce are a projection of his own internalized flaws. While he constantly criticizes Bruce for not being able to control his emotions, Tony himself is one of the most hot-headed Avengers. He holds Banner to a standard he can’t even meet himself. The culmination of Tony’s projected feelings toward the Hulk occurs when he facilitates Bruce's banishment from Earth, sending Banner spiraling into the true menace he becomes in the World War Hulk storyline. Stark’s role in the banishment compounded Hulk’s transformation into a monster and solidified his fractured relationship with the team.

5 Attacking Allies in Armor Wars

Tony's Struggle With Control Reveals His Villainous Nature

Tony Stark’s obsession with the power his suits hold turns him into a villain in Armor Wars. When Stark discovers his armor has been stolen and used by criminals, he takes matters into his own hands, vowing to disable anyone who uses his technology, no matter the cost. His actions spiral out of control as he attacks former allies, including government-sponsored heroes and S.H.I.E.L.D., treating them as enemies simply because they use his creations. This extreme reaction reveals a dark side to Stark, one where his obsession with control overrides his sense of justice.

Stark’s response to the theft of his armor is a betrayal of those he once called allies, attacking Stingray, Captain America, and even S.H.I.E.L.D. What starts as a quest to protect his technology quickly becomes a self-serving vendetta, where Stark disregards the safety of others to preserve his own power. Rather than seek collaboration or find a way to resolve the issue peacefully, Stark’s immediate response is to impose his will by force. Ultimately, his actions demonstrate that even the best intentions can lead to villainous outcomes when power is wielded without regard for ethical considerations.

4 Working with Kang

Stark’s Dangerous Alliance And The Betrayal of Time

Iron Man's secret alliance with Kang the Conqueror in the Crossing storyline highlights a shocking and dangerous side of his character. Rather than standing firm against a known villain, Stark secretly works with Kang, one of the most malevolent and manipulative forces in the Marvel Universe. This willingness to collaborate with a tyrant demonstrates Stark’s moral corruption, as he allows his intellect and resources to be used for destructive purposes. The depths of Stark’s betrayal are revealed when he aids Kang in manipulating the timeline and kills fellow Avengers like Yellowjacket and Gilgamesh.

Which MCU character Marvel quietly moved on besides Kang the Conqueror should reappear?

Kang the Conqueror is not going to be used by the MCU anymore, even though he had been set up to be the main villain of the next two Avengers movies. Albeit for very different reasons, Marvel has also quietly moved on from characters before, and I think some of them could do with an MCU return. Eternals was a movie that did not live up to expectations, but I think Dane Whitman is a character Marvel should bring back. Wasting a talent like Game of Thrones star Kit Harington makes no sense, and he could the Midnight Suns.

By enabling Kang to alter history, Stark not only betrays his friends but also jeopardizes the fabric of time itself. Stark’s complicity in such a catastrophic plan exposes the villainous streak that runs through his character, as he chooses self-interest over the protection of reality itself. Even though the Crossing storyline is later retconned, the impact of Stark’s betrayal remains. His willingness to abandon his morals and work with one of the greatest threats to the universe for his own selfish gain.

3 When Stark Actually Becomes A Villain

The Superior Iron Man Is The Real Tony Stark

The superior Iron Man storyline shows the true potential if Tony were to fully lean into his villainous tendencies. This version of Stark arises following the Axis event, where a magic spell reverses the morality of Earth’s heroes and villains. While most heroes regain their moral com, Tony is one of the few who remains "corrupted", revealing the depths of his potential for cruelty. This 'evil' version of Tony, equipped with the same brilliance and ambition, reveals the true threat Tony Stark poses to the world.

The creation of the Superior Iron Man is an exploration of the darker aspects of Stark's personality, such as his narcissism and unchecked ego. By releasing the Extremis 3.0 virus, Tony manipulates a large portion of society into becoming addicted to the viral app, which he then profits from by forcing them to pay daily fees and turning people into addicts enslaved to his will. His actions show that if Stark ever gave in completely to his darker side, the consequences would be catastrophic.

2 The Creation of Ultron

Stark's Vision Turned AI Tyrant

Tony Stark’s role in the creation of Ultron in Avengers: Age of Ultron is arguably one of the worst things Iron Man has done in the MCU. While the original intent was to create a global defense system, he instead made a destructive, vengeful entity bent on exterminating humanity. His inability to foresee the consequences of his actions ultimately leads to massive loss of life, including the devastation of Sokovia in the MCU. Ultrons' very existence is a testament to Stark's hubris and arrogance.

Marvel Rivals Ultron Leaks - Release Date, Abilities, & Everything We Know So Far

The second character in Season 2 of Marvel Rivals, Ultron, is set to release soon, but longtime leaks reveal much about his abilities, role, and more.

Although Stark takes responsibility for Ultron’s rampage, the damage is irreparable. His pride and his failure to recognize the true dangers of his creation mark a significant shift in his character. Ultron, as a direct result of Stark’s ambition and arrogance, becomes a villain in the broader narrative of the MCU and comics alike. Stark’s role in creating Ultron is a prime example of how his good intentions often lead to destructive outcomes. His actions have cost lives, broken friendships, and reshaped the MCU in ways that continue to echo throughout its history.

1 Tony's Role In Civil War

Stark Was Anything But Heroic In Marvel's Biggest Internal Conflict

One of the strongest arguments for Tony's true villainhood has to be his role in Civil War. Stark is the leading advocate for government oversight of superheroes and holds to that belief despite the massive casualties. While arguably well-intentioned, his stance ignores the autonomy of other superheroes and the potential for corruption within government oversight. Iron Man's rigid insistence on ability is ittedly a massive mistake and alienates those around him. The event demonstrates how Stark is willing to sacrifice his friendships and principles for the sake of order, which are not typically characteristics that are considered heroic.

Stark’s willingness to violently defend his position in this fight and impose his will on others demonstrates that his fascist tendencies are even stronger than the villains he claims to oppose

In Civil War, Stark’s betrayals aren’t just personal; they’re a direct attack on the very idea of freedom. It is the quintessential example of just how misguided Tony's principles truly are. Stark’s willingness to violently defend his position in this fight and impose his will on others demonstrates that his fascist tendencies are even stronger than the villains he claims to oppose. His conviction in these dangerous beliefs leads to the greatest fracture in Avengers history, making him arguably the greatest villain the Avengers have ever faced.
