The Hulk is known as one of the most powerful and destructive characters in the Marvel Cinematic Universe, but not every villain he’s fought has been equally challenging. Over the years, Bruce Banner’s green alter ego has battled everyone from ordinary soldiers to incredibly powerful beings who could destroy planets. While some enemies matched his strength, a few truly impacted the Hulk and his place in the MCU.
Figuring out which of the Hulk’s enemies are the biggest threats isn’t just about physical strength. It’s also about who challenged him on a personal and mental level, and how those conflicts shaped the story. From alien invasions to clashes with powerful gods and cosmic villains, the Hulk’s fights actually show how the Marvel Cinematic Universe has changed and grown.
The Chitauri Army

While the Chitauri army posed a huge threat in The Avengers, Hulk didn’t even consider them a real challenge. Used by Thanos and Loki as a disposable fighting force, the Chitauri easily defeated normal armies and almost took over New York City. But the moment Hulk joined the fight, everything changed.
Hulk effortlessly destroyed the Leviathans in the air, easily brushed aside enemy soldiers, and wrecked their high-tech equipment as if it were nothing. The Chitauri were numerous but lacked any real tactics or ability to adjust when facing Hulk’s incredible power. They were a threat to regular people and buildings, but Hulk wasn’t even slightly challenged by them.
The Chitauri were dangerous because there were so many of them. However, because they all shared a single mind, destroying their main ship completely defeated the entire invasion force. While they came in large numbers, Hulk wasn’t really threatened by them.
HYDRA Forces

The forces of HYDRA, prominently featured in Avengers: Age of Ultron, were a threat because of their technology, not their strength. HYDRA soldiers had powerful weapons, advanced technology, and experimental upgrades, making them challenging for the typical Avengers. However, for the Hulk, they were just more resilient targets to smash.
Even strong defenses and powerful weapons couldn’t stop him for very long. The real danger of HYDRA wasn’t their military strength, but how they used deception, secretly worked their way into positions of power, and planned large-scale destruction.
None of HYDRA’s weapons or tactics were effective against Hulk’s incredible strength. He easily destroyed soldiers and structures, and although they could momentarily hurt him, HYDRA never managed to stop or defeat him, which is why they didn’t consider him a major threat.
Thanos’s Army

The army Thanos commanded in the Avengers: Infinity War and Avengers: Endgame movies was a much greater threat than any invading force we’d seen before. His forces included groups like the Chitauri, Outriders, Sakaarans, and Leviathans. While the Outriders weren’t very intelligent, they were significantly faster, stronger, and more aggressive than the Chitauri.
The Sakaarans are bug-like soldiers who fight with different kinds of weapons. While individually they aren’t very strong compared to the Avengers, their huge numbers almost allowed them to conquer Earth. Despite this, Smart Hulk and Bruce Banner, piloting the Hulkbuster armor, were able to defeat many of them in battle.
Thanos’ army was truly dangerous because of how many soldiers they had. They could defeat armies and even the Avengers by simply overwhelming them, but they often needed to catch Hulk off guard or attack him with many soldiers at once. In a fair fight, most of these soldiers wouldn’t have stood a chance against him.
Cull Obsidian

As a huge Marvel fan, I’ve always been fascinated by Cull Obsidian. He was one of the few villains who genuinely seemed like a physical match for the Hulk – seriously powerful! This guy was a massive, heavily armored tank, and incredibly strong. What really stood out was his weapon: this huge chain-hammer that wasn’t just for smashing things, it could actually change into different weapons, making him even more dangerous against even the strongest Avengers.
Cull Obsidian was Thanos’s powerful enforcer, making him a natural match for Bruce Banner while Banner was piloting the Hulkbuster armor in Infinity War. Their fight took place during the Battle of Wakanda, and it’s famous for the moment when Hulk wouldn’t transform, prompting Bruce to jokingly call him a “big green asshole.”
Cull Obsidian was a formidable opponent, almost equal to the Hulkbuster in strength. However, Bruce Banner ultimately defeated him by launching him into Wakanda’s shield, which proved fatal. Although they were physically matched, Cull wasn’t as resourceful or quick-thinking as Bruce. Overall, Cull Obsidian posed a significant danger, but wasn’t quite as powerful as the Hulk.
General Ross And The US Army

In the early days of The Incredible Hulk, General Thaddeus “Thunderbolt” Ross and the US Army were Hulk’s biggest and most consistent adversaries. Though Ross wasn’t a physical match for Hulk, he posed a serious threat through his unwavering determination, access to vast military power, and willingness to take increasingly drastic measures. He repeatedly used the full force of the army to try and capture and subdue the Hulk.
In the early days of the Marvel Cinematic Universe, the military threw everything they had at Hulk – tanks, helicopters, even cutting-edge sonic weapons and experimental tech – constantly testing his strength. However, General Ross’s greatest challenge wasn’t overpowering Hulk, but relentlessly pursuing him. This forced Hulk to live as a fugitive, unable to find peace or control his own fate.
As Hulk got stronger, the military found it increasingly difficult to control him. However, General Ross was more successful than anyone else at trying to stop or defeat Hulk, especially in the beginning. This early impact is why he’s considered a significant figure in the story.
Abomination

The Abomination is one of the Hulk’s strongest and most evenly matched foes. Created using a twisted form of the Hulk’s own power, Emil Blonsky became his equal in size, strength, and ferocity. Their fight in Harlem, depicted in The Incredible Hulk, was incredibly intense and nearly defeated the Hulk.
As a critic, I’ve seen plenty of superhero clashes, but the Abomination stood out. He wasn’t just trying to win; he genuinely loved causing chaos and pain. That made him a truly frightening and unpredictable opponent for Hulk. While Hulk ultimately triumphed – it wasn’t just brute force, he had to really think his way through it and just outlast the Abomination – honestly, the outcome felt genuinely uncertain. It really could have gone either way, which made for a thrilling fight.
The creation of Abomination demonstrated that someone—or something—could rival, and even exceed, the Hulk’s power through scientific means. This makes Abomination one of the Hulk’s most formidable foes and constantly highlights just how unpredictable the Hulk’s strength can be. Abomination embodies what the Hulk could become, though he isn’t quite as strong.
Ultron Bots

Ultron posed a special threat because he drove Hulk to continuously unleash massive destruction. In Avengers: Age of Ultron, Ultron created hundreds of robotic copies of himself and constantly improved his own form. While each individual robot wasn’t very strong, their sheer quantity made them incredibly difficult to defeat.
As a huge movie fan, I was really impressed with how easily Hulk destroyed a lot of those robots. The highlight for me was definitely when he just tossed Ultron right out of the Quinjet – it was incredible! But, you know, even that wasn’t enough to actually stop Ultron, because he quickly jumped into another body. It was a cool moment, but ultimately, it didn’t solve the problem.
The real danger wasn’t the robots themselves, but Ultron’s ability to endlessly replicate and spread his programming, making him impossible to truly destroy. While Hulk could smash individual robots, he couldn’t stop them quickly enough to prevent widespread destruction. This constant reproduction made Ultron’s army a much greater threat than anyone realized.
Loki

Although Hulk quickly defeated Loki in their fight, Loki was a significant threat. He didn’t rely on physical strength, but skillfully manipulated world events in The Avengers, starting a war and trying to take over the planet. It’s important to remember his influence, even though Hulk won their confrontation so easily.

Loki was incredibly clever, magical, and skilled at manipulating others, and these abilities could have caused serious trouble for Hulk if Loki had used them more effectively. Loki recognized that Hulk was unpredictable and could have taken better advantage of that weakness. However, Loki didn’t fully appreciate Hulk’s strength, which ultimately led to his embarrassing loss.
I’ll never forget when Hulk just destroyed Loki with that “puny god” line! It was amazing to see Loki, who usually acts so superior, completely humbled and tossed around like nothing. Even though Loki didn’t stay a big threat for long, he was the one who really kicked things off and got the Avengers fighting together for the first time, so he’s still a pretty important villain in my book.
Fenris

In Thor: Ragnarok, Hela unleashed Fenris, a massive wolf that proved to be one of the few beings strong enough to physically challenge Hulk. Their fight on the Bifrost was a brutal and evenly matched clash, causing significant destruction. Fenris’ incredible size, toughness, and savage nature gave it the upper hand for most of the battle.
Hulk was seriously hurt when Fenris the wolf bit down on him – something that doesn’t happen often, considering how incredibly tough Hulk usually is. In the end, Hulk won by using his environment to his advantage, managing to throw Fenris off of Asgard.
Winning against Fenris wasn’t about brute force, but careful planning. Fenris was a wild, powerful enemy, much like the Hulk himself. The difficulty Hulk had in the fight proves Fenris was a truly formidable opponent, stronger than many others the Hulk has faced.
Thanos

Thanos is the villain who finally defeated the Hulk. Their battle at the start of Infinity War resulted in a quick and decisive victory for Thanos, marking the first time the Hulk had clearly lost in the Marvel Cinematic Universe.
It was incredible watching Thanos fight Hulk. He didn’t even need the Infinity Stones or fancy weapons – he just beat Hulk with raw strength and skill. Honestly, the biggest shock wasn’t the physical fight itself, but how completely it messed with Hulk’s head. He was so shaken, he refused to come out and fight for the rest of the movie! I’ve never seen anyone get to Hulk like that before – it was a total knockout, mentally and physically.
Thanos showed that simply being angry wasn’t enough to win, and he dramatically altered the Hulk’s position within the Marvel Cinematic Universe. In every way – physically, mentally, and in terms of the story – Thanos was the Hulk’s greatest challenge. Their fight in Infinity War clearly illustrated this, as Thanos easily defeated the Hulk in a way no one expected.
