This version of Brainiac, a composite of Brainiac from around the Multiverse, is revealed to be the pre-"Flashpoint" era Brainiac who, having found his way into the Source Wall and into the Multiverse, was thrown back in the timestream and mutated by the effects of "crisis" events such as "Crisis on Infinite Earths", "Zero Hour", and "52", creating a godlike being. He then uncovered the location of Vanishing Point from nearly killing New 52 Earth-0's Michelle Carter, from which he could roam the complete history of the Multiverse, collecting doomed cities from defunct timelines, alternative futures, and parallel worlds to add to his collection, in "Convergence", leaving behind an agent, Telos, to rule a planet of the same name containing the cities. Brainiac's attempt to do this to a future timeline of Earth-0 was narrowly averted by the heroes in the story ""; Brainiac was contained in a T-sphere, leaving Telos stranded without his master, prompting the events of "Convergence" in which the planets are bid to fight each other. When the events of "Convergence" nearly end in an irreversible destruction of the Multiverse, the time traveller Waverider, formerly the pre-"Flashpoint" Booster Gold, frees Brainiac, who reveals he is sick from his mutations and only wishes to return to normal, to being Brainiac of Colu. He sends most of the heroes home, and with help from the "Zero Hour" Parallax and the pre-"Flashpoint" Superman, averts the collapse of the Multiverse from "Crisis on Infinite Earths", and is returned to the normal Brainiac. His actions also allow various parallel universes and alternate timelines to exist as the new Multiverse.
