Doom will be from the Fantastic Four’s universe

There have been theories that the Modern Fantastic Four will originate from a universe outside the Sacred Timeline ( where most of the MCU takes place ) , explain their absence from the franchise and the retrofuturistic look of the 1960s Earth they will inhabit . Because of this , it seems likely that Doom will also transmigrate to the chief timeline with Marvel ’s First Family , possibly to escape the death induce by Galactus in their native reality .

This narrative choice will allow for the villain to share his classifiable animosity with the Fantastic Four as the team ’s archenemy , like in the comedian , giving their dispute with him inDoomsdaymuch greater weighting .

Doom will be a Tony Stark variant

Since Doom may come from an alternating universe , it stands to ground that Robert Downey Jr. ’s baddie will be an malefic version of his late character , Tony Stark . Thus , it is likely Doom ’s technical school will be a dissimilar version of the Iron Man armor , intermix science and sorcery to create a genuinely terrific foe .

Doom call for up the mantle of Iron Man when he tried to reform in the comics , wear a standardised courting of armour with his trademark fleeceable cloak . The villain ’s ill-famed Doombots may even be edition of Stark ’s Iron Legion or the subsequent golem watch created by Ultron inAvengers : Age of Ultron . If Doom turns out to be a Stark variant , the MCU could take full advantage of the Multiverse to let loose its most grievous mind , usurping another potent scientist whose future has undoubtedly changed .

Doom kills Kang (all of them)

It ’s no secret that Marvel Studios dropped the Lucille Ball withKang the Conqueror . Though it specify up the fourth dimension - traveling tyrant as the MCU ’s next big bad , the less - than - lucky reception ofAnt - Man and the Wasp : Quantumania , Jonathan Majors ’ legal troubles , and his subsequent firing have stimulate the studio to rethink its design for the Multiverse Saga .

One critical remnant of their initial plans that demand to be handle is the Council of Kangs , who appear after the destruction of the “ Exiled One ” inQuantumania , localise the stagecoach for a future warfare on the Avengers . Since Doom will take Kang ’s place as the franchise ’s overarching resister , how terrific would it be for Doom to jump his rampage by decimate all the other Kangs ? Such a twisting will extinguish this hang plot thread and show himself as a actual threat to the Multiverse .

Doom destroys the Multiverse

In the most recent Secret Wars risible storyline , readers witness Doom destroy the entire Multiverse in a serial of Incursions . However , the masked villain steals the might of the Beyonders with the assistant of Molecule Man to reshape the corpse of existence into a rum realm known as Battleworld , where various fictional character from the Marvel Universe revere Doom as their God Emperor .

Since the Void seems to have get hold of Battleworld ’s place in the MCU , it stands to understanding that Doom will do what Cassandra Nova could n’t and dress all of existence to mold his kingdom in the Void . This outcome would top Thanos ’s Snap in terms of world - shattering consequences , as well as set up the cosmic terminal battle inAvengers : Secret Wars .

Scarlet Witch will be an Anchor Being

Deadpool & Wolverineintroduced the concept of Anchor Beings to the MCU . Simply put , Anchors are figure with such great meaning that their death will destroy their respective timeline . This may be the MCU ’s version of “ Nexus Beings ” from the comic strip , mean that the Scarlet Witch may be revealed as the Anchor of the Sacred Timeline .

Wanda Maximoff has had quite a journeying in late years , having unlock her power with chaos deception and become one of the MCU ’s strong and most grave figures . Whether or not she meet her death at the end ofDoctor Strange in the Multiverse of Madness , she will likely function a greater purpose in next MCU film . She may even be a object for Doctor Doom due to her reality - shaping abilities , fulfilling the prognostication uttered by Wong of how she will “ either dominion or annihilate the cosmos . ”

Doom steals Loki’s power

Since Marvel seems to be conform the 2015Secret Warscomic series , it is potential that Doom will endeavor to slip the power of some all - powerful being like the Beyonder to reshape the Multiverse and become God Emperor Doom . Though the Scarlet Witch would be a prime candidate , another possible target would be Loki , the God of Stories .

Disney+’sLokisaw a variant of the titular character go from the God of Mischief to the guardian of all realities , advance the power to moderate prison term and reconstitute the Sacred Timeline into an entire Multiverse . Doom could steal such power from Loki , possibly using the power of the Scarlet Witch , in his architectural plan to destroy the Multiverse and recreate it in his image .

Spider-Man faces Doom

It would be no surprisal if such films put a spotlight on his conflicting family relationship with what may very well be an evil version of his former mentor . It would be like watch out Luke Skywalker having to campaign Darth Vader all over again .

The Avengers team up with Thanos

Since Doom is being represent as the next threat to the entire Multiverse , Earth ’s Mightiest Heroes will necessitate all the help they can get to barricade him . So what a twist it would be if the Avengers were forced to team up with one of their greatest adversaries : Thanos .

Though the evil Titan was killed inEndgame , the Multiverse opens the doorway for another variant of him to appear in the hereafter . Since the Multiverse seems to be on a collision course with itself , it would be no surprise if one of these timeline has a Thanos willing to help defeat Doom .

Galactus appears

Galactus is one of the most iconic and crucial villains in the Marvel Universe , and fans have waited age to see a comic - accurate Galactus rear his mammoth head in the MCU . Though the cosmic baddie will finally make his debut inThe Fantastic Four : First Steps , it would seem like a waste to have the world - avid entity appear in just one film .

Despite his status as an opposer , Galactus ’s compulsive need to consume planet has made his character coordination compound and constitutional to the correspondence of the cosmea . His character in the latter should very much go him to confront Doom in the oncoming Multiversal crisis in the next Avengers movie . Doing so would serve break the MCU ’s unsound habit of discarding its best villains in their introduction photographic film .

The Young Avengers will appear

Since Doom and Scarlet Witch may foil paths inAvengers : Doomsday , it seems likely that the MCU will adapt a storyline involving them and the Young Avengers call “ The Children ’s Crusade . ” This story get wind the young hero sandwich , who let in Wanda ’s son Wiccan and Speed , find an amnesic Wanda married to Doom and the villain steal her power .

Marvel Studios has been slowly build up up the Young Avengers with champion like Kamala Khan and Kate Bishop , who may recruit characters like America Chavez , Wiccan , Speed , Stature , and White Vision , all of whom have been introduce to the MCU . It ’s only instinctive that this new generation of Avengers unite the war against Doom in the penny-pinching future .

The X-Men will appear

There have been multiple way of life for the X - work force to bring together the MCU , and they have already been set up in labor likeDoctor Strange in the Multiverse of Madness , The Marvels , Deadpool & Wolverine , andX - man ’ 97 . give their absence seizure in the Sacred Timeline so far , it seems like the mutant Cuban sandwich will make the leap into the spotlight from another universe .

It see like worlds will start to collide with each other because of Doom join the MCU , so the X - Men appear to stop this cosmic threat will only give fans another reason to catch this impend blockbuster .
