Comments:
Only Superman and the Justice Society members know that the Black Canary who joins the Justice League is not the original heroine, but her daughter. The rest of the Justice League, and Black Canary herself, do not learn this until the events of Justice League of America #220. The true origin of her sonic powers is also revealed in that story for the first time. The powers are not, as suggested in this story, the result of Aquarius's magic, nor are they the result of Black Canary's journey between parallel Earths.

Synopsis:
Framed for misuse of public funds by John Deleon, Oliver Queen loses his fortune and his investment company, and begins to doubt his usefulness as Green Arrow. Meanwhile, as the other Justice League members vote on the admission of Black Canary as a new member, she begins to exhibit strange sonic powers over which she has limited control, supposedly, a result of her exposure to Aquarius's magic sphere.

Another side-effect of Aquarius's power then materializes the members' evil natures as separate entities, and battle ensues. By disguising one of his robots as his own evil self and defeating it, Superman encourages his fellow crusaders in their struggles with their own opposite numbers. Green Arrow's battle amounts to a direct confrontation with the self-doubt that had been plaguing him, and when he defeats his other self, he regains his confidence.
