The Shaggy Man

Few villains in the Silver Age could rattle the Justice League quite like The Shaggy Man, who crashed onto the scene in 1966's Justice League of America #45, conjured up by the legendary creative team of Gardner Fox and Mike Sekowsky. This DC menace has shared pages with heavy hitters like Green Lantern, Hawkman, and The Flash — Hal Jordan himself among them — which tells you something about the kind of threat this creature represents. Spanning two decades of comics history and earning a spot in Who's Who: The Definitive Directory of the DC Universe, The Shaggy Man is one of those gloriously wild Silver Age creations that embodies everything bold and imaginative about that era.
