Justice League of America #220 (DC, 1983 — Cover A)

Sargon the Sorcerer joins forces with the Justice Society in their battle against the Crime Champions. The Flash and Hourman take on Chronos and the Fiddler; Red Tornado and the Huntress fight Dr. Alchemy and the Icicle; and Power Girl and Sargon tackle Felix Faust and the Wizard. Meanwhile, the Thunderbolt recounts for Starman and Black Canary the secret of her true origin. Johnny Thunder and Black Canary had been crime-fighting teammates at the start of her career, until Johnny decided to forgo the use of his T-Bolt and Black Canary eventually took his place in the JSA. Larry Lance became Dinah Drakes boyfriend, and after the Justice Society disbanded in the 1950s, the two were married and had a daughter, also named Dinah. When the child was still an infant, however, the Wizard, seeking revenge on Black Canary, cast a spell giving the baby uncontrollable sonic powers, and the tearful parents allowed the T-Bolt to take the child to his home dimension, where her power would do no harm. The Thunderbolt then caused everyone to forget what had happened. His story is interrupted at this point, as the Earth-2 Johnny Thunder frees himself and overcomes his counterpart, thus allowing the T-Bolt to revive the JLA heroes, who join the fight against the Crime Champions, with the result that the villains are soundly beaten. Superman and the Spectre then appear in the Thunderbolt Dimension to complete the tale of Black Canarys beginnings, as it is revealed that the original Canary had died shortly after her husband (in JUSTICE LEAGUE OF AMERICA #74), and that the Black Canary who joined the Justice League was actually the child Dinah Lance, now grown to adulthood, able to control her sonic powers, and imbued by the T-Bolt with her mothers memories.
