||After the JLA learn of the JSA's crisis from Red Tornado, they leave to aid them vs. Aquarius. Meanwhile, as both Fate's and GL (Alan)'s energies begin to wane inside their bubble due to exhaustion, Aquarius saves them, but makes them his slaves. Under his control, they fight the JLA, and as Starman's rod energies begin to increase dramatically, an enormous energy ball forms, which threatens to kill Black Canary, trapped by one of Green Arrow's stickum shafts. Her husband, Larry, awakens from Aquarius's control and sacrifices his life to save her. Both teams then regroup and fight Aquarius and defeat him. Canary then leaves the JSA for Earth-1 permanently over her husband's loss.
