MCU Theory Suggests Thor Is The Only One Who Can Defeat Scarlet Witch. Thor could somewhat easily beat Wanda Maximoff, the Scarlet Witch, in a fight, and this is exactly how he would do it.
While Thor is one of the most powerful beings in the MCU, it is known that Scarlet Witch's powers are superior.
Wanda may not be as physically strong as Thor, but her abilities far exceed those of Avengers such as Captain America and Spider-Man. Here's what makes her one of the most powerful Avengers.
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.
Thor can throw stormbreaker towards her, but so what? It's easily dodgeable and SW can telekinetically lift it since it doesn't require worthiness to lift it. Thor can struck lightning upon her, so what? Scarlet Witch has Force Fields, meaning she can create shields that will make his lightnings ineffective.
MCU Theory Suggests Thor Is The Only One Who Can Defeat Scarlet Witch. Thor could somewhat easily beat Wanda Maximoff, the Scarlet Witch, in a fight, and this is exactly how he would do it.
Captain America
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.
Once Wanda learns how to use them properly, there's a good chance that she will be unstoppable. Much like Hela, Scarlet Witch would simply overpower him. It wouldn't be anything close to a fair fight.
Chthon Possesses Her
The Scarlet Witch loses a major battle as well as her agency to Chthon in Avengers #185-187, a powerful demon who authored the Darkhold. Chthon, among the most powerful magical beings in the Marvel Universe, attempted to use Wanda as a vehicle to enter the world the night of her birth.
She's Uncontrollable
If Scarlet Witch is able to unleash a huge dose of her powerful Chaos Magic in a fight with Superman, it could be enough to completely stop Superman, even if it's just for a few moments. This will give Wanda a chance to land as many blows on him as possible before he is able to recover.
When it comes to using their innate power, no doubt Captain Marvel will win over Thor. She can easily absorb all thunder attacks that Thor channels at her in a fight. On the other hand, Thor may have a difficult time countering her powerful photon blasts.
Thor is Immortal, Not Invincible
In Avengers: Infinity War, Thor revealed that he was over 1500 years old. It's clear that age doesn't affect him the way it does normal mortals, as with most immortals, he is aging at a slower rate. While Thor will eventually die, it will take thousands of years for it to happen.
Who would win between Thor and Ghost Rider? Ghost Rider without a doubt. He is immortal, nigh on unkillable demon. Thor is pretty powerful himself, but can be and has been killed.
Can Elder Goddess of Chaos Scarlet Witch beat Odinforce Thor while she is holding back not to kill him? So can GOC Wanda defeat Odin Force Thor in a way that does not involve killing him? Yes. She has infinite power and it's stated multiple times that her power threatens all of existence.
That's not to say Loki would crumble. Physically, he is stronger than Scarlet Witch, but if these two titans ever go up against each other in the battlefield of the mind, I think Scarlet Witch will come out on top — at least the first time. You can fool Loki once, but he is nothing if not infinitely adaptable.
In a fight, Scarlet Witch would win 8/10. He has a nanotech armor suit that he can manipulate to shoot multiple energt blasts, lasers, sheilds, swords, etc. He can also use the suit to adapt to fighting styles and can take hits directly from the Power Stone.
Wanda was considered to be the Nexus Being of Earth-616, but there were still forces far more powerful than her. Perhaps the most obvious character that was more powerful than the Scarlet Witch was the One Above All, who acted as the "god" of the Marvel universe.
One of the most powerful is Chthon. Chthon has often set his sights on Scarlet Witch, as her massive power appeals to the beastly god, and he's possessed her many times. While the Avengers have always been able to break his hold over her, she has never been able to beat the god on her own.
There's no denying that the Scarlet Witch can't hold a candle to Captain Marvel in terms of raw physical strength. 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.
Can Wanda defeat Wolverine? The MCU version of Scarlet Witch may not fare as well as she'd hope against Wolverine, but the character in the comics almost certainly could. Wolverine may be a better physical fighter and have accelerated healing abilities, but Wanda is one of Marvel's most powerful beings.
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.
Who will win a fight between Ghost Rider and Scarlet Witch? Rider should take this because her telekinesis would be useless against him. Rider could easily use the penance stare and destroy her.
In a direct physical speed matchup, The Flash will definitely trounce Thor. After all, The Flash has been calculated to travel at ludicrous speed, as fast as13x the speed of light!!!
However, Thor, one of Marvel's strongest Avengers, might just be powerful enough to take on Superman. With his Asgardian abilities and mystically-enchanted hammer Mjolnir, Thor is a god who fights and defeats adversaries far stronger than him on a regular basis.
