The Marvel Cinematic Universe is filled with gods, aliens, and powered humans capable of reshaping reality, but not every superpower is created equal. Characters like Doctor Strange, Scarlet Witch, and Thor wield abilities that can alter the entire fate of the multiverse. However, others either weren’t very useful, were severely underdeveloped, or just didn’t translate well on-screen.
Importantly, this list focuses on actual superpowers in the MCU timeline. This article does not consider humans relying on advanced tools or technology, like Whiplash and the Wrecking Crew. Instead, these rankings highlight MCU characters who, despite being gifted with unusual abilities, rarely managed to use them effectively, were nerfed compared to the comics, or were easily countered by opponents.
Quicksilver Couldn’t Outrun Bullets In The MCU
Quicksilver, played by Aaron Taylor-Johnson, was introduced in Avengers: Age of Ultron as the MCU’s speedster counterpart to his comic book and X-Men versions. However, his powers were dramatically downgraded compared to expectations. While super-speed should have made him one of the most formidable heroes in the Avengers’ lineup, his actual feats in the film were underwhelming.
The most infamous example was his death. The MCU’s Quicksilver couldn’t outrun a hail of bullets while trying to save Hawkeye and a child. In the comics, Quicksilver can easily dodge projectiles and react faster than bullets, but the MCU made him slower for the sake of dramatic storytelling.
Quicksilver could have moved Hawkeye out of danger without even being touched. Yet instead, he became a one-movie hero whose potential was wasted. His speed wasn’t just limited; it contradicted the logic of his own powers.
Medusa’s Prehensile Hair Was An MCU Downgrade
In Marvel Comics, Medusa’s prehensile hair is one of the most unique powers in the Inhuman roster. She uses her hair as a weapon, shield, and tool, making her a dangerous and versatile fighter. However, when the Inhumans TV series adapted her character into the MCU, her powers were rendered nearly useless.
Within the very first episode, Medusa’s living hair was shaved off with ridiculous ease. The villain Maximus managed to disarm Medusa with a simple set of clippers, leaving her without her trademark ability for most of the show’s runtime. Instead of showcasing how effective and creative her hair could be in combat, the series stripped her down to a powerless leader.
It wasn’t just a downgrade from the comics. It was one of the weakest portrayals of superpowers in Marvel’s on-screen history. By removing her powers so quickly, the show robbed Medusa of her uniqueness and left audiences wondering why she was even included in the first place.
Danny Rand’s Iron Fist Was Rarely Useful
Netflix’s Iron Fist introduced Danny Rand as the mystical martial artist who channels his chi into his fist to unleash devastating power. In theory, this ability should have made him one of the most formidable fighters in the MCU’s extended canon. In practice, however, his power came with too many restrictions.
Danny needed to “charge” his Iron Fist, which meant that in the middle of battles, he was often unable to use it when it was needed most. Worse still, the show rarely allowed him to wield it in inventive ways. Instead of fighting like a martial arts powerhouse with superhuman augmentation, Danny too often fought like a normal fighter with occasional bursts of light.
The narrative rarely gave him time to showcase his full potential. This made his powers feel more like an inconsistent gimmick than a reliable ability. The result was a disappointing translation of a fan-favorite hero.
Drax’s Superstrength Varies Wildly
Drax the Destroyer was introduced in Guardians of the Galaxy as a powerful warrior whose superhuman strength and durability made him a key member of the team. However, across the films, his strength has been depicted inconsistently. His abilities often depended more on plot convenience than on his supposed powers.
In some scenes, Drax is able to rip through enemies with ease, showcasing his immense physical power. Yet in other moments, he is tossed around like a rag doll by foes who shouldn’t logically overpower him. In some scenes, he can tear through hordes of alien soldiers with ease.
Yet he is unable to escape the monster he was swallowed by in Vol. 2’s iconic opening scene. This inconsistency makes it unclear just how strong he’s supposed to be. Unlike characters such as the mighty Hulk, whose strength feels more consistent, Drax’s superstrength fluctuates so wildly that it undermines his credibility as a warrior.
Extremis Became A Riskier Supersoldier Serum In The MCU
In Iron Man 3, the Extremis program created enhanced humans who could regenerate from injuries, withstand incredible damage, and unleash fiery energy. Accordingly, this should have been one of the most impressive forms of superhuman power introduced in the MCU. However, it came with a mᴀssive drawback: instability.
Extremis subjects were prone to overheating and exploding. This turned their powers into a ticking time bomb rather than a reliable enhancement. While characters like Aldrich Killian were able to weaponize Extremis effectively, most of its users burned out quickly, literally.
Compared to the stability of the Super Soldier Serum used on Captain America, Extremis was far more dangerous to the people using it than to their enemies. Its flaws made it more of a liability than a true superpower. Extremis left its bearers vulnerable to self-destruction instead of becoming lasting additions to the MCU’s lineup of powered individuals.
Odin’s Odinsleep Left Him Open To Attack
Odin, as the All-Father of Asgard, is one of the most powerful beings in the MCU. His mystical might, wisdom, and strength place him at the top of the cosmic hierarchy. Yet his most famous weakness is his Odinsleep: a form of restorative hibernation that he must periodically undergo to recharge his power.
While the Odinsleep keeps Odin alive and maintains his formidable strength, it is also incredibly dangerous because it leaves him completely vulnerable. In the MCU, this vulnerability allowed Loki to seize control of Asgard during Odin’s slumber. The sleep’s duration is also unpredictable, lasting as long as Odin’s body needs to restore itself.
This means that even though Odin is a godly powerhouse, his greatest weakness is built into his biology. The Odinsleep has practical benefits and grants him his powers. However, it effectively transforms the most powerful Asgardian into an open target whenever he needs to recover.
Mantis’s Empath Abilities Only Flourished Once
Mantis is one of the more unusual Guardians of the Galaxy, introduced with the empathic ability to sense and influence emotions. She can also put people to sleep through physical contact, making her potentially useful in team scenarios. However, in practice, her powers contributed very little.
In Avengers: Infinity War, Mantis’s biggest moment came when she helped subdue Thanos by putting him in a trance. Frustratingly, that plan was immediately ruined when Star-Lord lost control and attacked. Indeed, for much of her early appearances, Mantis was treated more as comic relief than as a functional member of the team.
It wasn’t until Guardians of the Galaxy Vol. 3 that Mantis’s abilities were shown to their fullest potential. Here she proved to be an invaluable member of the Guardians while escaping Orgocorp, pitting foes against each other. Still, for years before that, her powers were portrayed as one of the weakest skillsets in the MCU.
Sprite’s Illusion Creation Was Potent But Harmless
In the infamous Eternals movie, Sprite possessed the power to create incredibly realistic illusions, capable of tricking even her fellow immortals. Her abilities had amazing potential for deception, confusion, and psychological warfare. However, they were also limited in terms of actual combat.
Unlike characters like Mysterio, Thanos, and Scarlet Witch, Sprite’s illusions couldn’t cause direct harm. This left her dependent on others to capitalize on the confusion she created. In group battles, her tricks were useful for brief distractions, but against determined opponents, illusions weren’t enough to stop or defeat anyone outright.
Sprite’s frustration with her eternally young form was also reflected in her powers, which seemed flashy but lacked real-world impact. The visual effects of her illusions were certainly some of the most creative in the MCU. Yet their lack of offensive or defensive power made her one of the weaker members of the Eternals and the MCU overall.
