Hey look, a Justice Society of America and Hawkman crossover!
One of the long-running arcs in Geoff Johns' Justice Society run is about Black Adam's role as an ally and enemy of the Society. So, when the JSA releases the terrorist known as Kobra in order to prevent him from unleashing a wave of Suicide Bombers, Adam gets pissed. He and the equally pissed Society member Atom Smasher quit the team.
The duo grab up some of Atom Smasher's former Infinity Inc. cohorts, including Northwind and Brainwave Jr., who drops the junior in the intervening time. This new team tracks down and executes Kobra, and they appoint two new members: Nemesis (the lady one) and Eclipso (with Alexander Montez as the host).
The group goes into Black Adam's former homeland of Kahndaq and conquers it. So the JSA heads in to stop all of that. Between the JSA book and Hawkman's comic, the crossover is really more of a JSA story that Hawkman is also in. But it's a really fun book!
Lasting Impact: The aftermath of the story would continue to play out in the JSA for a while, until it got a sequel in the later story, Black Vengeance. Which is also good!
