Countdown

Superman-Prime battles Monarch, angered at the destruction of his "perfect Earth" with Monarch opening his containment suit and causing a nuclear explosion. The pair continue fighting until Superman-Prime rips apart Monarch's suit causing an explosion that wipes out the entire Earth-51 universe, leaving only the Monitor alive.

The Challengers manage to survive before Donna sees a message written by the Source, commanding them to go to Apokolips. The Earth-51 Batman is killed in front of Jason's eyes by Ultraman who is sent flying by Kyle. The Monitor of Earth-51, having heard the call of the Source, arrives and opens a portal for them to Apokolips.

In the Nexus, Solomon is about to kill Forerunner when Darkseid appears and requests he finish the chess game they have been playing since Countdown began.
