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". 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.
