The Super Bowl trailer for Doctor Strange In The Multiverse of Madness is one of the most packed MCU previews ever, with tons of split-second glimpses of new locales and characters. The trailer confirms the existence of some characters in the movie and also hints strongly at a large number of major Marvel characters who are most likely to appear.

Some of those confirmed are variants of main characters, like Doctor Strange and the Scarlet Witch. Others are hinted at in visuals or dialogue, including a major character from the Fox X-Men franchise who likely blows open the door to many other massive cameos from iconic Marvel Comics characters that could change the MCU forever.

Characters Confirmed To Appear In Doctor Strange In The Multiverse Of Madness

Loki

Loki talks to Sylvie in the Loki finale.

Though he doesn't appear in the trailer, Loki is reportedly confirmed to appear in the movie. This makes enormous sense given where he was left at the end of his series and where the movie is going with the multiverse and alternate timelines.

Loki's actions in his series broke the sacred timeline and unleashed an infinite number of variants of Kang The Conqueror into existence, some of whom could rule the alternate dimensions that Doctor Strange travels to in the course of the movie.

Iron Man

The trailer gives a tantalizing glimpse of a character who appears to be a variant of Iron Man. While it's an open question what version of the armored Avenger this is, context clues confirm that the founding character of the MCU is returning in some form.

This version of Iron Man is likely the Superior Iron Man, a powerful variant of Iron Man from the comics. His armor glows red hot in battle and he wears a silver suit that is very similar to the Ultron drones also present in the trailer.

Ultron Drones

The trailer threw a major curveball at fans by revealing the presence of what appear to be Ultron drones. These drones are very similar to the drones Tony Stark created early in the MCU, but are far more advanced and don't seem to be controlled by Ultron himself.

The lack of red eyes likely means they're working for Iron Man, meaning that his variant is responsible for the capture of Doctor Strange. This likely takes place in another universe the Sorcerer Supreme has traveled to.

Scarlet Witch Variant

The Scarlet Witch encounters a variant of herself in Doctor Strange In The Multiverse of Madness.

The trailer confirms that there is at least one other variant of the Scarlet Witch in the movie, and she may actually be the villain. An intriguing scene shows the Scarlet Witch back in her house in Westview, which is now in virtual ruins. She's approached by a variant covered in blood.

This variant is seen throughout the trailer and she seems to be fighting Iron Man and also possibly attacking the facility where Doctor Strange and America Chavez have been captured by the Ultron drones.

Defender Strange

A Doctor Strange variant uses his powers in Doctor Strange In The Multiverse of Madness.

There are a number of variants of Doctor Strange in the trailer. One of the most intriguing now confirmed to be in the movie is one who appears similar to the comic book version from modern runs of The Defenders comic book. He could play a major role in the movie.

This variant is seen in the TV spot announcing the full trailer, and he is fighting the tentacle monster seen in other shots. He also is interacting with America Chavez, who comic book fans know can punch through different realities.

Characters Likely To Appear In Doctor Strange In The Multiverse Of Madness

The Maximoff Twins

If the evil variant of the Scarlet Witch hasn't accepted the loss of her children as the MCU Wanda has, she may seek out variants of them in the multiverse. Tommy and Billy Maximoff are very likely to appear in the movie if that's the case.

Comic book fans know that Tommy and Billy go on to become founding of the Young Avengers, a team that is coming together in the MCU with Kate Bishop and others, so it's likely fans will see them again in some form.

Reed Richards

A shocking voiceover in the new trailer from Patrick Stewart opens up tremendous possibilities. One of the biggest is the likelihood that fans will see Reed Richards in the new movie, thanks to his association with the Illuminati from Marvel Comics.

Comic book fans know Mr. Fantastic is part of the secret council with Professor X and if this council is the one that captures Doctor Strange in the movie, then it is very likely that a variant of Reed Richards appears. The only question will be which one - the Reed from the Fox movies or a new one?

Namor The Sub-Mariner

Another major member of the Illuminati likely to appear in the movie is Namor The Sub-Mariner. The King of Atlantis has been rumored to appear in the MCU for years and his connection to the council is the most logical place for it to happen.

Namor is a major Fantastic Four villain and also an antagonist occasionally of Black Panther, making him a major figure in the future of the MCU. The movie may decide to debut a variant in the Doctor Strange sequel or the actual MCU Namor.

Professor X

Doctor Strange appears to talk to Professor X in Doctor Strange In The Multiverse of Madness.

The most surprising reveal of the trailer is the voiceover from Patrick Stewart during the council scene. While he could be playing any number of characters, most likely he is reprising his iconic role as Professor X from the Fox X-Men franchise.

This makes a ton of sense, given the MCU has already opened that door with the appearance of former Spider-Man movie characters in No Way Home. Professor X is a member of the Illuminati in the comics, and he could also be the key to other movie characters making a cameo.

Wolverine

If the Fox X-Men Professor X is in the movie, then it would be hard to imagine Wolverine not being with him. Fans have long wanted to see Hugh Jackman's iconic Logan in the MCU and he has expressed willingness to do it in the right circumstances.

This movie gives fans the perfect opportunity. A variant of Wolverine could appear, perhaps younger or older than versions that have appeared in other movies. He could be part of the Illuminati council or one of its associates throughout the multiverse.
