The most important thing is that Flash can move faster than the speed of light, so if he wanted, the Scarlet Speedster could take out every member of the Avengers before they even knew the fight had started.
The Avengers are powerful but if the full might of Darkseid was brought against them, they'd fail. Thor and She-Hulk might be able to hold out a bit but the rest of the team would be dead quickly after Darkseid showed up and in the end, even they would fall to the dark lord of Apokolips.
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.
Thanos defeated the One Above All in The Infinity Conflict storyline. Thanos used the so-called “Astral Regulators” and their powers to bring an end to the ultimate creator.
While the two company's heroes are pretty evenly matched in some places, DC's are just too much for Marvel. Beyond the fact that DC's heroes are overall more powerful, they have numerous advantages. From magic-users to Kryptonians to the Flash Family, Marvel can't match DC's power.
Cap is one of the few mortals able to not only lift Mjolnir but wield its full power, making him someone who can beat Thor. Assuming the reason for their battle is because Thor is possessed or tricked, Cap would be able to use Mjolnir against him.
Even on a bad day, Superman can surpass the Hulk in terms of mental as well as physical strength.
The Presence is the incarnation of the Abrahamic God in the DC Universe. The Presence has the ability to empower various angels, including the Spectre, Eclipso, and Michael Demiurgos.
If anybody from the MCU could defeat Superman, it's Scarlet Witch. After defeating five members of the Illuminati, consisting of Professor X, Captain Marvel, Captain Carter, Mr. Fantastic, and Black Bolt, we don't want to imagine what Scarlet Witch could do to Superman.
Captain Marvel is the most powerful and powerful Avenger in the Marvel Cinematic Universe (MCU). Her incredible powers and determination have made her a valuable member of the Avengers.
#1 Iron Man
Played by Robert Downey Jr., Iron Man consistently ranks as one of the most popular characters, in the Marvel Cinematic Universe—and for a good reason.
But after the release of WandaVision and Doctor Strange in the Multiverse of Madness, it's pretty clear that the Scarlet Witch is among the most powerful. Wanda Maximoff has never truly been defeated, only "losing" to the combined forces of Doctor Strange, Wong, and America Chavez after realizing the error in her ways.
If Superman had no weaknesses at all, no Avengers would have a chance in front of him. While Superman is known for his incredible strength, speed, and other superhuman abilities, there are a few Avengers who could potentially give him a run for his money.
Martian Manhunter's powers make him one of the Justice League's most potent members. It's that mix of abilities that will help Martian Manhunter beat Scarlet Witch. Not only is he a physical powerhouse on par with Superman, but his shapeshifting, invisibility, intangibility, and telepathy make him even more versatile.
1 DARKSEID
It just so happens that one of the many gods Darkseid has beaten or killed is also Zeus, along with the other Olympians-- it was basically an Mt. Olympus clearing operation.
The Old Gods were slain during the War of the Gods by Ares, who was later killed during the last days of World War I by Wonder Woman, Zeus' daughter with Hippolyta.
Darkseid is often considered one of the most powerful villains in the DC Universe and is a force of evil so powerful he tends to be treated as the final threat in other media from the DC Animated Universe to the final season of Smallville.
The Hulk is the strongest one there is in the Marvel universe. His strength is potentially infinite and he has a powerful healing factor that means he doesn't stay hurt for long. Shazam has a lot of powers at his disposal, but he's just not ready to deal with the Hulk.
While Superman is one of the most powerful heroes in the DC Universe, enhanced to godlike levels by the Sun's radiation, The Flash's physics-defying powers are capable of killing him not by playing on his famous vulnerability to magic or his weakness to Kryptonite, but simply by hitting him so hard, even his ...
None of Cyborg's powers and skills would do him much good against the Hulk. He'd give it a try, of course, but the Hulk would quickly overwhelm him.
Zeus. It should come as no surprise that, in a one-on-one battle of Zeus vs Thor, Zeus would easily triumph.
In a fight, all Zeus would need to do is get his hands on some kryptonite to weaken Superman and easily defeat him. While Superman would likely still give a good fight, it's unlikely he'd be able to defeat a god. Since Zeus has all of the Olympian Gods under his control, finding kryptonite wouldn't be difficult.
Thor is great at close-range combat, too, which is one of Wanda's weak points. Captain Marvel and Captain Carter were able to get in a few blows before succumbing to the Scarlet Witch, and that is because they got close enough to her to do it.
