- The Antimonitor uses the Psycho Pirate (whom he captured in issue 3) to control the last 3 known surviving earths heroes: 4 (Charlton comics characters), S (Marvel family), and X (Freedom fighters), as he begins to destroy their universes while the other heroes from 1 and 2 go to warn them about the antimatter attack. Alex Luthor Jr. is about to sacrifice his unique energies (matter/antimatter mix) to transport all 3 universes into limbo alongside Earths 1 and 2 when Harbinger stops him and uses her powers instead. All fades to black and white as we then see all 5 earths and their universes now in limbo. To be continued...
1st appearance Wildcat II. 1st appearances of recently acquired Charlton heroes in old DC multiverse (as mentioned in issue 1 notes). 1st full physical appearance of Antimonitor.
