Determining the strongest Avenger in the MCU is tricky since each brings something unique to the table, and Thor and Hulk are the top contenders in terms of sheer physical strength. However, regarding versatility and range of abilities, Captain Marvel and Doctor Strange are formidable opponents.
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.
Wanda was still a formidable adversary, capable of tipping the scales in favor of Ultron (James Spader) or the Avengers, depending on who she was helping. Still, without her Chaos Magic from Marvel Comics, Wanda was not more powerful than Thor or Hulk.
While Thor is one of the most powerful beings in the MCU, it is known that Scarlet Witch's powers are superior.
Hawkeye might be considered the weakest Avenger in the Marvel Cinematic Universe due to the extent of his abilities, but his best superpower has nothing to do with a bow and arrow. From the moment the McU's Avengers were assembled, Jeremy Renner's Clint Barton has stood out a bit.
Hulk has traditionally been seen as the strongest Avenger physically — and for good reason, though he's been subdued by both Iron Man and Thor. Then he got wrecked in the opening scene of "Infinity War" and we haven't seen him fight since.
Hawkeye. On numerous occasions in the comics, Clint Barton has said he's just a regular guy with a bow and arrow. Unfortunately, his lack of power usually leads to him suffering injuries regularly and has led to fans deeming him the weakest member of the Avengers.
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.
In the aftermath of his failure, Thor had a new-found determination to kill Thanos and undo the Snap. The remaining Avengers converged on the Titan's home to find him wounded and the Infinity Stones destroyed. Seeking vengeance, Thor raised Stormbreaker and, with one fell swoop, beheaded Thanos.
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).
Zeus. It should come as no surprise that, in a one-on-one battle of Zeus vs Thor, Zeus would easily triumph.
Kang is stronger than Thanos, with the Conquerer being much more challenging to defeat than the Infinity Gauntlet-wielding villain.
Captain America
He would never stay down and was always ready to face unbeatable odds if there was a chance he could save the day.
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.
Spider-Man can be pretty silly, but he's tough as nails and his spider-senses and agility, combined with super strength, have allowed him to beat Hawkeye every time they've fought.
1 Galactus
Marvel has many powerful immortals, but few can match Galactus. The World Devourer controls the full might of the Power Cosmic, which gives him near complete control of energy and matter.
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.
While Thor is powerful and his strength is said to be unmatched, he is not strictly immortal like other mythological gods. He is susceptible both to aging and to being killed in battle. Like other Norse gods, he must consume special apples kept by the goddess Idun to keep from aging.
Thor wins. Not only is Thor a better combatant and more experienced, but he also can be stronger than Shazam by using Megingjord to augment his superhuman strength. Additionally, Thor is more invulnerable than Shazam and has a better understanding and grasp of magical and mystical energies.
Who does Zeus fear? In fact, there is one myth that shows Zeus to be afraid of the goddess Nyx. It is commonly thought that Nyx is the only goddess that Zeus is truly afraid of because she is older and more powerful than him.
As the current Flash in DC Comics, Wally West is one of the fastest men alive, easily able to outpace people like Superman and manage to keep up with people like Barry Allen, but a long time ago Wally admitted that the Reverse Flash is much faster than him.
Quicksilver, Marvel's Answer to The Flash
The other is in the Marvel Cinematic Universe, Quicksilver is played by Aaron Taylor-Johnson in Avengers: Age of Ultron (2015). Less popular, but probably because this version of Pietro didn't last long. Regardless, there aren't many things this speedster can't do.
