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.
