Transmutation

A very cool power that Doctor Strange possesses is the power of transmutation. Transmutation is the ability to change one material to another by altering its molecular state and anything can be changed into anything else as a result.

Strange has utilised it to do things like changing a gun into a swarm of flies (as seen in the image above), but it can undoubtedly be used on a much grander scale than that.

In the Marvel Cinematic Universe, it could, for example, be used to undo any transmutation that Thanos does in Avengers: Infinity War. In the Infinity Gauntlet comic book arc, the Mad Titan used transmutation quite a lot (such as when he turned Wolverine’s body to mush, for example) and Strange would come in useful in the MCU if that kind of thing was to occur.
