There are a number of different heroes in the MCU, with over 25 Marvel movies and a handful of TV episodes now available. There are a variety of various talents exhibited, and the heroes all have varied power levels, from the familiar characters that have been in the franchise since the beginning, such Iron Man, to the younger heroes being revealed after Thanos‘ defeat, like Shang Chi.
Naturally, not every hero can be all-knowing and all-powerful. People must be able to strive against something in the movie in order for it to have a decent storyline and engaging tale that they will want to see. That something is almost always the villain or, in certain circumstances, the group that is actively fighting the hero. Even still, as the comics show, there are heroes who could take on Thanos on their own. In comparison to such times and heroes, this list depicts the weakest of the group, who would require all the assistance they could obtain to combat a massive alien attack.
7. Black Widow
It’s self-evident that individuals without superpowers would be among the weakest in a world full of them. Natasha Romanoff is a skilled assassin, hence she is very lethal to any average person. When compared to characters like Scarlet Witch, who might easily defeat Thanos in a one-on-one fight, a lethal assassin doesn’t seem that impressive. Even in her own film, Black Widow, she spent the whole time attacking other humans, the majority of whom were also professional assassins like her.
Neither the original Hawkeye, Clint Barton, nor the more recent Hawkeye, Kate Bishop, who made her MCU debut in the Disney+ program Hawkeye, have any particular abilities. Without the specialist Black Widow training, Barton isn’t nearly the assassin Romanoff is, but his S.H.I.E.L.D. training does offer him an advantage over Bishop. The only thing she and he have in common is perfect aim and a fondness for bow and arrow. In any case, when a superhero lacks powers but others do, they are inherently the weakest in the group, exactly as Romanoff.
Falcon doesn’t measure up to some of the MCU’s more formidable characters, whether in his initial debut in Captain America: The Winter Soldier or his most recent appearance in the TV program The Falcon and The Winter Soldier. Sam Wilson had military training with his special wing jetpack before Avengers: Endgame, and that was the end of it. He’s simply a regular person with no special talents, save that, unlike Iron Man, his suit is riddled with flaws and he lacks expensive weaponry. All he has is the shield, even after he becomes Captain America. He’s not just different from Chris Evans‘ Captain America in that he lacks the powers that Steve Rogers possessed, therefore he’s still susceptible.
Ant-Man is an intriguing instance on the list since, at first glance, the powers the suit grants him, such as ant strength and the ability to shrink to the size of an ant, appear to be more strong. When you look at Scott Lang, the good-hearted criminal, you’ll notice that he doesn’t exploit the costume to its full potential. His enormous heart makes him less likely to fight, and he rarely wants to inflict serious damage on purpose, regardless of who he’s up against. Lang is among the weaker heroes due to his pleasant nature, which makes him less inclined to fight and more likely to chat.
Quicksilver made one appearance in the Marvel Cinematic Universe, in Avengers: Age of Ultron. There, he demonstrates his superpowers, which include superspeed. While heroes with superspeed, like his X-Men world counterpart, can be extremely strong, Pietro Maximoff is a minor character in the film. He saves a few lives, knocks Captain America out, annoys Hawkeye, and then gives his life. Perhaps he enters this list because we see so little of him, but there are certainly more powerful heroes with what we have.
In the comics, Starlord fought Thanos on his own, although that was with the help of a cosmic cube. He’s considerably less strong in the MCU. In Guardians of the Galaxy, Peter Quill is half human and half celestial. While this appears to give him more strength at first, he is only aware of his other side for approximately half of the film, and after they beat Ego, he loses his newfound abilities. This reduces Quill to a mere human gunslinger, something he clearly lacks in comparison to the MCU’s other heavy hitters.
It should come as no surprise that Mantis is the MCU’s weakest hero. In volume two, she joined the Guardians of the Galaxy and demonstrated her empathic abilities to the public. While she did have one major scene at the conclusion of the film where she momentarily put Ego to sleep, thereby holding him off for a few minutes, it was the only time she appeared to be in charge. She also attempted to keep Thanos at bay by attempting to put him to sleep for a short period of time, but he was able to fight back and finally triumph. Aside from that, she hasn’t really assisted in conflicts, and reading people’s emotions isn’t particularly useful either.
