Justice Alliance Of America's History
During the Crisis on Infinite Earths, the Justice Alliance were warned by Pariah and Lady Quark about the coming of the antimatter wave that will destroy their universe. The first signs of this imminent threat shown when the Justice Alliance's underwater base was destroyed by an earthquake. Upon regrouping at Superman's Fortress of Solitude, the Justice Alliance gained the help from the Justice League of America of Earth-One. But shortly thereafter, the Anti-Monitor made his attack on Earth-D by dispatching his Shadow Demons. Superman, Hawkman and Hawkgirl were killed from the assault. After a ceremony to honor their dead, the remainder of the Justice Alliance return to their homes to make peace with their own families.
