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 Maximoff Is the Most Powerful MCU Character
And since the MCU was designed to please everyone, not only comic book readers, downgrading most characters' powers helped to keep the movies grounded until people were addicted to Marvel Studios' colorful universe.
This revelation sheds light on how Wanda uses her powers, and she needs her sense of sight to control her hexes. If there's one superhero who can totally beat her, it would be Spider-Man.
Therefore, by the end of the Infinity Saga, Captain Marvel was likely stronger than Wanda, all things considered. However, after discovering the true nature of her powers in WandaVision and accessing the Darkhold magic in Doctor Strange 2, Scarlet Witch is now more powerful than Captain Marvel.
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.
As the only Avenger that proved capable of single-handedly defeating him, Wanda ranks easily as one of the most powerful Avengers.
Thor's immense strength, combat prowess, control over lightning, and enchanted hammer, Mjolnir, make him a formidable opponent against Scarlet Witch. In Avengers: Age of Ultron, he demonstrated his ability to resist her reality-warping powers and even physically overpower her.
However, with Doctor Strange in the Multiverse of Madness, the Scarlet Witch's candidacy is thrown for a loop. That's because the film reaffirms the angry version of Wanda wouldn't have been able to kill Thanos.
Scarlet Witch's Powers Can Easily Defeat the Hulk (Under One Condition) Scarlet Witch has proved her magic can stop the Hulk, but the specific spell she needs to use has one condition to be effective. Avengers' Scarlet Witch has already proved she can defeat the Hulk, but only under a specific circumstance.
While the Scarlet Witch is one of the most powerful beings in the Marvel Universe, her greatest weakness proves even Spider-Man can beat her.
Wanda can do the same with Kal-El. Seeing that the Sun is the source of all his strength, it's only a matter of how she chooses to depower him. Even without her reality-bending powers, her chaotic magic works against him. With magic as his weakness, her attacks will more than damage him.
Doctor Strange in the Multiverse of Madness proves without a shadow of a doubt that Wanda Maximoff, the Scarlet Witch, would and does beat Doctor Strange. Strange puts up a good fight, but it's not the good Doctor who stops Wanda.
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.
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.
Arishem is so powerful that he created the Eternals, a race of beings that, in and of themselves, are also incredibly powerful. His intentions may not always align with what's good for the Earth, but Arishem is probably the most powerful being we've met in the MCU, at least to date.
Many mutants harbored deep resentments toward Wanda, even after she reformed, and Rogue perhaps most of all. Rogue killed the Scarlet Witch in the Uncanny Avengers series, during a mission to stop the Apocalypse Twins.
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.
If it came down to it and Odin saw Scarlett Witch as a threat to the Universe and Multiverse and decided to try and take her down, who would win? Odin. Odin could probably kill her but not in a strait up fight.
The source of Wanda's unnatural abilities stem from a two-fold base; unparalleled mastery of actual magic and an innate power to warp reality. Due to exposure to mystic energies and forces at an early age, Wanda may reshape reality to various extremes.
Wanda is a very interesting character. She's practically omnipotent. As far as power weaknesses go, she doesn't really have any. Her real weakness is her mental instability, and how easily she can be manipulated.
Mostly, Vision is pretty much a direct copy of Superman, as he is able to fly, shoot lasers, and have super-strength. Superman could quite easily beat Vision with just these three abilities.
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).
