Countdown #15

Countdown - Splitting The Atom / The Origin of Doomsday
On Paradise Island, Mary has been found by Holly and Harley and brought before Hippolyta who asks her to join them. On Earth-51 Kyle and Ray battle Monarch's forces. Ray tells Kyle that this Earth's Palmer had discovered the Morticoccus virus and realised that it might exist in the other universes. As he was immune to it, he planned to seed the other Earths with his own immunity, providing an inoculation. After he died, Ray continued his work and where he inoculated someone, he left them with a mark like his Atom symbol (see The Search For Ray Palmer) Batman allows Jason to go free and reveals the reason there is little crime on the world when he shows him evidence of having killed most of the super villains of Earth-51. Donna battles one of her counterparts who lets slip that she is working with Queen Belthera (see Countdown #33 - #35) At the Nexus, Superman-Prime attempts to force Solomon to help him before they are interrupted by Forerunner who has arrived to kill the Monitor. In Bludhaven, Brother Eye continues to assimilate the city using Firestorm as a power source and Karate Kid wonders whether, because of Desaad's presence, it now has Boom tube technology.
