Earth-Two/A

Aquarius
Aquarius was a sentient living star, whose cosmic essence came to Earth to plague Starman. He tapped into the power of Starman's Cosmic Rod to increase his own power. Starman's comrades in the Justice Society of America came to his aid, but Aquarius defeated them all. Red Tornado recruited assistance from the Justice League of America in the Earth-One reality, but by the time they arrived, Aquarius had the entire JSA under his thrall. During this event, Larry Lance - husband of Black Canary, Dinah Lance, was killed by a star-burst hurled by Aquarius. The Green Lanterns of both realities, Alan Scott and Hal Jordan, chased Aquarius into outer space where they tricked him into entering the Antimatter dimension. This ultimately destroyed Aquarius' form.
