The Doctor Strange 2 movie reveals why Scarlet Witch failed to stop Thanos when they clashed.
Attention SPOILERS. Scarlet Witch y Thanos had two face-to-face confrontations, the first in Avengers: Infinity War (2018) when the great villain intended to acquire the Mind Gem what had Visionat that moment she manages to stop the villain and break the powerful object, but then Thanos hits her and resets to Visionthis is how you acquire the last Infinity Stone. The other confrontation was in Avengers: Endgame (2019) during the great final battle. Scarlet Witch he used all his power and is about to crush Thanosbut the enemy ships start shooting and manage to shoot it down.
So even though she is shown to be super powerful, she was not able to stop the villain. However, in the movie Doctor Strange 2 can defeat heroes like Black Lightning, Captain Marvel, Captain Carter, Professor X y Reed Richards, with hardly any effort. But there is a substantial change between the Wanda Maximoff a few years ago and the one who has been studying the Darkhold.
To begin with, after the events of WandaVision, can be considered to Wanda Maximoff how Scarlet Witch, since that is when he awakens his true power. Afterwards, he decides to spend some time studying the darker magical arts until he decides to attack America Chavez in other realities. Therefore, the most powerful version of him is at that moment and not when he faced Thanos. That’s why he really doesn’t look like a match against him when he has the Infinity Gauntlet and neither when they fight hand to hand in Avengers: Endgame.
Since the multiverse presents infinite possibilities, it is clear that there is a reality where Scarlet Witch has developed its full potential and when it arrived Thanos was able to defeat him. Something similar to what happened in the Land of the Illuminati. Although on that occasion, it was the Doctor Strange contaminated by the Darkhold who defeated him. In fact, you get to see the corpse of Thanos when black lightning mata al Sorcerer Supreme.
The movie Doctor Strange 2 is currently in theaters, while the rest of the installments where it appears Scarlet Witch can be seen in the Disney Plus streaming platform.
