A new promo trailer called "The Multiverse" for Doctor Strange has been released by Marvel and it gives us a very fast, but very definite look at Dormammu.
For those who may not be aware, Dormammu is one of Doctor Strange's main nemesis and is formed out of pure fire. The trailer shows Doctor Strange, Mordo, Kaecilius and Dormammu all in about 56 seconds. It's a really quick glimpse, but we can definitely tell that it is Dormammu. We've known that Dormammu is in the film due to some early reports, but just how much has yet to be determined. He may be a focal character, teased for a sequel or simply referenced as in the trailer here.
Take a look at the trailer up top and two screens below showing Dormammu. The two eyes you can see in Doctor Strange's vision before Kaecilius slams a ball of energy onto the ground. The vast purple void is also Dormammu's eye that is staring right back at him.
Doctor Strange hits theaters in the U.S. this Friday, November 1st.
