With what we have seen in the movies her power comes from her hands and she needs to concentrate,if she were to trap Thor like she did to Thanos,Thor can still summon lightning or control strom breaker or mjionir to kill her or knock her out. What ever version of Thor will kill her.
Thor is strong; Wanda is powerful. Power doesn't have to mean raw strength, but the tremendous demonstration of one's own ability. Thor could beat Wanda in an arm wrestling contest, but Thor is still susceptible to Wanda's mind powers.
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.
In the main Marvel Comics continuity, despite all her power, the Scarlet Witch could not stand next to god-like forces such as the Phoenix Force, Galactus, and the Living Tribunal. Wanda was considered to be the Nexus Being of Earth-616, but there were still forces far more powerful than her.
However, Odin and Mjolnir may still have the last laugh since, by negating the spell, the Scarlet Witch could potentially remove the hammer's ability to grant its wielders Thor's power. So, while she could technically lift Mjolnir, Wanda might just end up turning Thor's mighty hammer into an extra-heavy paperweight!
She concluded her mass murder by killing Professor Xavier, arguably the most powerful telepath in the Marvel universe. The mere fact that she can single-handedly destroy five of Earth's mightiest heroes easily makes her the strongest MCU character.
Additionally, Wanda demonstrated just how powerful she was in Infinity War, when she was able to repel Thanos while simultaneously destroying Vision's Mind Stone. So it stands to reason that Wanda would have been able to single-handedly whoop Thanos into oblivion, had he not called in cover fire from above.
His lightning attacks could disrupt her energy manipulation abilities, giving him an even more significant advantage in battle. Thus, Thor is undoubtedly one of the few Avengers who stands a chance against the formidable Scarlet Witch.
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.
Although characters like Magneto and Storm can beat MCU's Wanda in a fight, Scarlet Witch's powers in the comics can only be compared to a handful of other Marvel characters. That short list includes Kevin MacTaggert, also known as Proteus, an energy-hungry mutant whose body cannot contain the amount of power he has.
While Odin is the god with the power originally. Odin knows magic just as well as Wanda does, shown through his enchantments, and some of his feats. Odin wins, unless he falls into the odinsleep.
The power of the Scarlet Witch is such that even gods from various comic stories would struggle to battle her at the height of her abilities.
yes, loki can beat wanda with just her hexes alone, but with chthon backing her up, loki is simply no match... think of it this way.... chthon is basically loki's great great great great great grand father. he is a part of the for original elder gods of demuirge, and pantheons are just the spawns of those gods.
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.
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.
Thor wins in a fight against Scarlet Witch almost every time. One can't neglect Wanda's incredible powers, especially her reality-warping and telepathic abilities. However, she still has the durability of a regular human being.
However, things could go the other way around too, with the red superhero throwing Scarlet Witch off her game with his words and getting the best of her. That being said, the latter's powers are beyond the merc's control, so it's safe to say Wanda will take down Deadpool with The Darkhold.
WandaVision confirms Scarlet Witch could've beaten Thanos in Avengers: Endgame all on her own, if he didn't call in reinforcements.
In the MCU, Scarlet Witch may put up a good fight, but Thor wins majority if not all of the fights. Scarlet Witch is definitely powerful but she is a glass cannon, one Stormbreaker strike and she dies.
Scarlet Witch's most important aspect in this fight is that she has the ability to defeat Superman. He is not impervious to magic, so her hits will damage him.
In a world that loves pitting popular characters against each other, one would wonder if Hela and Scarlet Witch ever met in battle, who'd emerge victorious? Hela would win in a fight against Scarlet Witch.
The Verdict: Scarlet Witch Is Stronger Than Captain Marvel
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. Now, as the Scarlet Witch, she doesn't even have to move objects with her mind to get what she wants.
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. Remember when the Webslinger covered his foe's entire face with his web? That is one of his signature moves!
As her powers likely come at least in part from the Mind Stone inside of Loki's scepter, Wanda's abilities include telekinesis, energy manipulation, and some form of neuroelectric interfacing that allows her to both read thoughts and also give her targets waking nightmares.
