Marvel has alluded to Carol's weakness against magic quite a few times in the books. But in a battle against Superman, she is practically invulnerable. She won't have to use Kryptonite to defeat him because she could take advantage of the red sun radiation.
Captain Marvel
Her powers could not only stand a chance against Superman, but most likely beat him as well.
Could DCEU Superman beat MCU Captain Marvel? Superman would win 9/10, that 1/10 is if Superman spammed his heat vision and marvel became overloaded with energy. But without that, there's no possible way for her to win.
It's natural that there are beings in the Marvel universe who can take him down. Sentry, Molecule Man, Gladiator, and Blue Marvel are all different adaptations of the Man of Steel concept. Then there are the Celestials and cosmic entities in the Marvel universe who are powerful beyond the scope of conception.
The Verdict: Scarlet Witch Is Stronger Than Captain Marvel
That said, Wanda has an edge due to Chaos Magic and her reality-warping abilities. Her telekinesis alone could nearly kill Thanos faster than Carol's punches. Now, as the Scarlet Witch, she doesn't even have to move objects with her mind to get what she wants.
Moon Knight's power level is often up for debate, but every night he demonstrates that he is capable of taking out each of the Avengers.
He's not weak to magic. It's never been a thing that he's weak to magic. The only time Superman has been overcome, is when he's held himself back. Superman at full strength would kill Wanda.
While Superman could potentially overpower Thor, blows rendered by the mystical Mjolnir would likey impose serious damage on the Kryptonian hero.
Despite the fact that he has bested several magic-powered foes in the past, Superman has no real defense against the Scarlet Witch. While Wanda's human form could allow Superman to best her in a purely physical fight, her ability to alter probability and use magic inevitably puts the odds in her favor.
Hyperion is able to absorb cosmic energy, which gives him incredible strength, super speed, flight, atomic vision, and a weakness to the isotope Argonite. Though hardly alone in this regard, he's usually considered Marvel's Superman.
Since they both possess superhuman strength and speed, their fight might go on for days. However, according to Greg Pak — Marvel's writer, who worked on several comics featuring the Hulk, Superman would win their fight because of his virtues: “Superman, being who he is, will not just make his enemy angry.
Even though Superman is often considered the most powerful character in the DC Universe, Shazam definitely comes close, and he can even beat the Man of Steel. And with a massive power upgrade, there's no question that Shazam can meet Superman blow for blow—despite the upgrade's terrible side effects.
But in All-Out Avengers #5, it's Captain Marvel's turn to run out of luck as Spider-Man defeats Carol Danvers with a disturbing attack involving webs directly shot down her throat. Spider-Man and Captain Marvel, despite being very different heroes, actually share a romantic history.
Green kryptonite weakens Superman and other Kryptonians, and can and will kill them with long-term exposure. Kryptonians under green kryptonite's effects experience severe muscular weakness, usually to the point of collapse, and excruciating pain, with both conditions progressively intensifying.
Thanos would win in a battle against Superman. He has more powers and abilities at his disposal and excels at both unarmed and armed combat, which was never Superman's greatest strength.
Yes, as a shock to many, Superman has briefly lifted the mighty hammer in a phenomenal crossover with Marvel and DC Comics.
The two heroes have raced several times since then, in the comics, cartoons and movies. As a general rule, the comics claim that The Flash is the faster hero, with Barry Allen, Wally West and even an octogenarian Jay Garrick having outrun Superman over the years.
As far as strength is concerned, it's pretty much a wash. Earth's yellow sun gives Superman immense strength, while Black Adam's strength is, literally, a gift from the gods, specifically Amon. A street brawl between the two could go on for days with neither gaining the upper hand.
Superman has no special resistance to magic, so to beat Strange, he'd need to use his speed to avoid any dangerous, magical attacks. Superman may be WAY faster and stronger than Strange, but the years of experience and resources Strange had pulled him the win.
Strange wins this one because he's used to this sort of fight. He's always facing down foes who are more powerful than him in some way. Superman's weakness against magic doesn't automatically give Strange the win, but that combined with the sorcerer's experience will let him triumph.
Hercules / Zeus
While not cosmic (none of that on this list!), he can survive the vacuum of space and resist cosmic attacks. He ranks above Thor here because he's technically the stronger of the two. In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
There are few beings in the universe Thanos is scared of and the Hulk is one of them. There's a good reason for this, Hulk's strength is potentially limitless. One of the things that makes the Hulk so dangerous is that if you can't take him out quickly, you're never going to take him out.
In terms of physical strength, Sentry is the most powerful being in the entire Marvel universe, and his powers are similar to Superman. It's just that Sentry has a much more advanced brain and also has telepathic abilities, which allows him to win over Superman.
Thor. Blessed with the powers and long life of a god, Thor was undoubtedly the most powerful member of the initial version of the Avengers. Not only can he fly and transport between worlds, but he was also the only one capable of taking down Thanos, even after he had assembled all six Infinity Stones.
