The fourteenth film of the MCU, Doctor Strange will be the one to finally bring the magic into the MCU. Previously, the magic of the Asgardians was described as being advanced science that humans couldn't possibly comprehend, while Scarlet Witch was the result of experiments with an Infinity Stone. As such, Doctor Strange will have to face a villain with similar power, Kaecilius.
This is one of the complaints regarding the MCU - the villains always have the same kind of powers and skills as the heroes. Ant-Man, Iron Man, Thor, and Captain America have all fought enemies who were enhanced in the same way they were. Is this a sign that Marvel lacks other kinds of characters? Is this a sign that the MCU lacks imagination?
Not at all, according to Kevin Feige. The Marvel boss explained that these kinds of villains were needed at first in order to establish the heroes' own skills. Thus, the Iron Monger was the perfect antagonist for a first flick featuring Tony Stark, Loki was the cerebral Asgardian counterpart of Thor, and Red Skull was basically the evil Captain America.
So obviously Doctor Strange will face a villain with similar abilities. As Kevin Feige explains, this problem with the villains will slowly become nonexistent. And we have already seen this - Iron Man 3 is the best example of this, while Guardians of the Galaxy also went a different route.
As the MCU expands, more characters will be introduced, thus giving the studio the chance to come up with better villains:
Clearly we will get to that [non-doppelganger matchups]"¦You want to have characters that inhabit the same world when introducing a new world, a new mythology for lack of a better term. You want to explore that as much as you can (via Screen Rant).
From this point of view, Feige is actually right. However, this doesn't explain characters such as Whiplash or the fact that Captain America is still fighting against supervillains enhanced in the same way he is.
Looking forward to Guardians of the Galaxy: Vol. II and the coming of Thanos, who is above all villains and all superheroes of the MCU!
