The Invisible Destroyer

Few villains carry a name as deliciously ominous as The Invisible Destroyer, who burst onto the Silver Age DC scene in 1965's Justice League of America #41, conjured by the legendary team of Gardner Fox and Mike Sekowsky. This is a character whose debut placed them squarely in the company of heavy-hitters — Green Lantern, The Flash, Hal Jordan, Batman, and Robin — which tells you something about the kind of threat DC wanted to project from the very first appearance. Though the catalog footprint is select rather than sprawling, the character's presence echoes across nearly five decades of DC continuity, surfacing in retrospective landmarks like DC Universe: Legacies. For the Silver Age completist or the collector who loves tracking down the overlooked corners of DC's rich history, The Invisible Destroyer is exactly the kind of discovery that makes digging through back issues so rewarding.
