Justice League of America (1960-) #224

Clark Kent, Hal Jordan and Oliver Queen are enjoying an afternoon lunch at a Star City bistro. Oliver’s partner Black Canary, however, is on the job, ready to take down an apparent mugging in progress. The potential victim, though, is far from helpless. He is a costumed adventurer called the Paragon, and he easily dispatches the would-be muggers. Canary is almost ready to help Paragon, until she realizes that he intends on killing his attackers. At this point, the two face off against each other, but Paragon appears to be able to execute Black Canary’s judo maneuvers even better than she can. The League members return to the Justice League Satellite and bring their teammates up to date on this new potential threat. Green Lantern researches Paragon on the computer and learns that he is actually Joel Cochin, a scientist living in Star City. Black Canary is eager to track him down and execute a little payback.
