The real Doom

Throughout the first half of the series there was speculation that Doom may not be the real Victor Von Doom. Doom was younger than the real Victor would be, his face was unscarred (when he first materialized), and his memory was fragmented; he had no recollection of how he came to 2099, and only a few memories of conflict with the Fantastic Four. Doom would later in the series recall the end of the "Age of Heroes", killing Reed Richards, growing old, and some vague memories of a war.

Ultimately, despite much speculation, the truth behind Doom 2099's identity was finally, definitively established as being the true, albeit alternate future version of Earth 616 Victor Von Doom on the final page of Doom 2099 Issue #25.^[8]

One Nation Under Doom

With his mind restored, Doom set out to conquer the United States, but by now he had lost several of his allies: Wire's body had died, though his mind lived on in Cyberspace; Poet died battling drug-traders; and Xandra had left to train in Wakanda. Doom conquered the US in issue #29 and left behind Fortune as regent in Latveria. As president, Doom fought against Alchemax, the Pixel Corporation, and the other corporations who controlled all aspects of everyday life in 2099. Doom recreates S.H.I.E.L.D., assigning Junkpile to take down the Red Market (illegal trade in humans for experimentation). He also made the X-Men 2099 the law enforcers of Halo City, a place where mutants and humans could live in peace. After Doom conquered the US, all 2099 titles added the letters A.D. (Anno Doom) to their titles.^[9]

Rage Against Time

Doom returned to Myridia, the world's source of information, hoping to find a way to save Latveria. He traveled back to the 20th century, battling his own present day self, as well as the 20th century Daredevil and Namor. Despite this, he successfully introduces an addictive crab venom to his country, leading the populace to develop an immunity to the necrotoxin in an effort to save his people in the future. He returned to 2099, to find Fortune and about 50% of the population of Latveria alive, due to the genetic immunity, though many Latverians had been mutated into humanoid creatures dubbed "mutalocos".^[10] Immediately upon his return, Doom is greeted by the Phalanx, who had returned to Earth to attempt assimilation of the human race again. Against the advice of Fortune's brother, Kaz, Doom agrees to aid the Phalanx in finding sleeper agents they had left on the planet to have a better chance at assimilation, though it would seem that Doom is merely lying to further his own goals. This storyline ends the Doom 2099 book and continues in the 2099: World of Tomorrow book, which combined all running 2099 titles into one.^[11]

2099: World of Tomorrow

The Doom 2099 character was one of many to appear in the new title 2099: World of Tomorrow. Castle Doom had survived the ice caps melting, being one of the few places still above water. Doom is seemingly in league with Magus, the emissary of the Phalanx, assisting him in finding the scout which contains a code that will begin the Phalanx assimilation. In reality Doom has been experimenting on humans, with the help of Xina Kwan, former lover of Miguel O'Hara, to find a way of purging the Techno Organic Virus. Spider-Man eventually arrives and Doom blackmails him into assisting their experiments, claiming to be in possession of Miguel's brother. Magus reveals he has known all along where the scout, Nostromo of X-Nation, has been and that contact is at hand. Miguel and Xina successfully introduce and purge the virus from Doom's neurotech armor. He claims that he had always intended to allow the Phalanx to find Nostromo, as the techno organic growth has purged his country of outside influences and the ravages of the past century. Just as Spider-Man is about to destroy Nostromo, Doom activates a code he had implanted in the scout years prior, allowing Nostromo to purge the Phalanx from the Earth. Doom is destroyed along with Magnus and with his final will names Nostromo heir to the throne of Latveria.^[12]

Ragnarok Now

Doom is shown searching for a way to prevent the Timestream from collapsing after it is damaged by the efforts of the Earth-616 version of the Red Skull. As reality begins to unravel around him, Doom is rescued by Kang the Conqueror, who recruits him as part of a larger plot against the Apocalypse Twins.^[13]

Deathlok-dominated future

In the pages of Savage Avengers, an unidentified Earth has its 2099 dominated by Deathloks led by a variation of Ultron who has taken the name "Deathlok Prime". Doom 2099 was shown to be an inmate at Hellrock Prison where he was held in a special area. When a time-displaced Dagger comes upon his cell, Doom 2099 is offered a deal to join the Avengers. Doom 2099 accepts so that he can take his revenge on Ultron.^[17]

Exiles: World Tour

Doom would find new life during the "World Tour" run of the Exiles series. He is revealed as the current monarch of Latveria and hacks into a public eye camera to offer the Proteus-possessed Hulk a safe haven in Latveria. After Proteus decides to leave, Jordan Boone (the creator of the "Virtual Unreality" portal that Proteus traveled through) is fired from Alchemax, but Doom, intrigued by the thought of inter-dimensional travel, offers Boone a new job.^[18]

While the original 2099 imprint is known as Earth-928^[19] in the Marvel Multiverse, this event causes a divergent timeline known as Earth-2992.^[20]

Timestorm 2009–2099

Victor Von Doom appears in the Timestorm mini-series that returns to the 2099 universe. In this mini-series he is an aged version of his original universe self that has sustained the world from disaster and has pulled the 2009 versions of Spider-Man and Wolverine into 2099 as his life is nearing an end.^[21]

Marvel Knights 2099

An apparently immortal via body-hopping Victor Von Doom appears in Marvel Knights: 2099 that features an alternate take on the 2099 universe. Doom appears in Marvel Knights 2099: Black Panther 2099, where aged and dying, Doom, seemingly employing the mind transferral ability he learned from the Ovoids, seizes the body of his current major domo Lucien in an apparently ongoing program implemented to ensure his continued survival. Donning his trademark armor and declaring "One Doom, One Legacy" the now reborn von Doom incinerates his former incarnation, apparently, though not explicitly stated now containing Lucien's mind, but he does mumble something before his immolation at Doom's hands. Seizing opportunity, the rejuvenated Doom leads a Doombot invasion of Wakanda, which dominates the country for months, until a young council member named K'Shamba fights back. He assumes the mantle of the Black Panther and destroys the rest of the army, seemingly stopping Doom's plans. However the ever-living Lord of Latveria has already won the nation, as K'Shamba is already his unknowing puppet.^[22] '

Reed Richards

In the new future of 2099 launched in 2099 Alpha, an alternate Reed Richards has appeared as Doctor Doom. Set on Earth-2099, Doom and Reed confronted each other after the UN decided to declare war on Latvaria. They were taken to the future after a scarred Reed took Doom into Victor's time platform with Reed having intertwined memories with him believing he was Doom.^[23]
