Countdown

Following the capture of Jimmy Olsen by Mary Marvel, Donna Troy and Kyle Rayner attempt to get the Justice League to help them. Elsewhere, Mary delivers Jimmy to Darkseid who reveals that the souls of the dead New Gods reside within Jimmy and his powers are reliant upon Darkseid. Before he can kill Jimmy, Superman arrives and battles Darkseid. Donna, Kyle and members of the Justice League arrive and attack Mary who manages to defeat them. Darkseid turns Jimmy into Kryptonite which almost kills Superman. Hidden inside Jimmy's brain, however, is the Atom who manages to disable the Apokoliptian technology that Darkseid had planted, allowing Jimmy to gain full control over his powers for the first time.
