In this series, Prin Vnok, an underling of Brainiac, uses his technology to travel to the End of Time to retrieve Doomsday in order to combine the beast's massive power with Brainiac's formidable intellect after Brainiac's original body was badly injured in his last fight with Superman (this was explained as having taken place at the time of the timeline's reconstruction following the events of "Zero Hour"; the reconstruction of time meant that Brainiac was able to change the events of Doomsday's defeat).
