Moon Knight Can Defeat All of the Avengers In His Sleep — Literally.

Hercules / Zeus
In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created. According to legend, he replaced Atlas in holding the sky on his shoulders.
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.
Green Goblin would love nothing more than to beat Spider-Man, but he can't. The two have been at each other's throats for a very long time; Spider-Man understands how to battle his foe, but Green Goblin never learns.
While Captain America is undoubtedly one of the Marvel Universe's most formidable hand-to-hand combatants, Spider-Man's unique and often-underestimated abilities make him more than a match for Steve Rogers.
Tony Stark is the smartest of them all, having been responsible for some of the most incredible inventions to have ever graced the Marvel universe, including the Arc Reactor and one of the most sophisticated artificial intelligence systems known to man.
While Quicksilver is often thought of as the fastest of the Avengers, one hero fans know from the movies can actually outrace him when they need to. Many heroes possess enhanced speed, but Pietro Maximoff is generally considered Earth's fastest man (at least in Marvel Continuity).
The Avengers, led by Chris Evans as Captain America, assembling in the Battle at the Avengers Compound. The Battle at the Avengers Compound sequence was praised by /Film as an improvement from Avengers: Infinity War, while scenes from the sequence were positively received by cinematic audiences.

#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.
By most accounts, Superman seemingly outclasses Thor in terms of raw strength, especially in earlier versions of the DC Universe. He's pulled planets, punched people into orbit and performed all sorts of wild feats of strength.
Marvel fans know that Spider-Man is a strong superhero, but the company has just confirmed that Peter Parker is strong enough to defeat the Incredible Hulk in a one-on-one brawl.
The Hulk may be one of Marvel's strongest superheroes, but one of the most underrated members of the X-Men, Havok, can defeat him in one simple move. Cyclops' brother, Havok, is one of the few Marvel superheroes who can defeat the Hulk in a fair fight.
In both Marvel Comics and the MCU, Iron Man is no pushover, but one story showed that even with his full arsenal, he can be taken down singlehandedly by the Guardians of the Galaxy's Gamora.

While Thanos is an Eternal and has the standard powers of super-strength, agility, regeneration, immortality, and more, Adam Warlock takes the upper hand. He can be killed, but he resurrects to be stronger every time.
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.
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.
Superman is Superman. He is going to be on every list that ranks superheroes by speed, strength, durability, endurance, etc. You name it, he's on it. Of course, Superman is much, much faster than a regular old bullet.
United States. The United States of America is a North American nation that is the world's most dominant economic and military power.
