Spectre
DC Comics.
Golden Age Spectre Archives 1 (Fun Comics 52-70; w Jerry Siegel; a Bernard Baily). [From DC Comics: By 1940, Jerry Siegel had accomplished something that very few writers could ever match - together with artist Joe Shuster, he created not just a character, but a whole new archetype. With their first story in Action Comics #1, Siegel and Shuster had created the brand-new concept of the superhero, and their character Superman had become an almost overnight sensation. But Siegel wasn't finished yet. Now he faced a challenge: What could possibly follow a character who was already the most powerful man on earth? The answer was a hero who was even more powerful - The Spectre! The Spectre was actually a policeman named Jimmy Corrigan who was killed while trying to save his fiancee. After meeting a "higher force" in the hereafter, he was returned to the world of the living with the knowledge that he could have eternal rest only when he had wiped out all crime - a pretty tall order! There was virtually nothing the Spectre could not do, and if, even to this day, he didn't manage to eliminate every criminal from the face of the Earth, it wasn't for lack of trying. Name a power and odds are the Spectre had it and used it in his "take no prisoners" battle against crime. Artist Bernard Baily was the strip's co-creator, and his solid yet rough-hewn storytelling propelled each ten-page story as fast as the Spectre's vengeance! So let us return to those simpler days when criminals were criminals and heroes were... well, omnipotent, wrathful ghosts!]
