Forbush-Man's first major appearance was in the lead story of "Not Brand Echh" #5 (Dec. 1967): "The Origin of Forbush-Man", which was "conceived, created and cluttered-up" by Lee and Kirby. In this story, Forbush-Man's secret identity is revealed as Irving Forbush, the fictitious office gofer at Marble Comics. The character has a shrewish maiden aunt (Auntie Mayhem) who is indirectly responsible for her nephew becoming a superhero: In a fit of pique, she slams the fabled cooking pot over Irving's head, inadvertently providing him with the disguise he'd been looking for. The fictional October 13, 1939, edition of the "Daily Bugle" claims an "Irving Forbush" was born on Friday the 13th, his parents Stan and Jacqueline wanting a daughter instead. Like his better-known Marvel contemporaries, Forbush-Man triumphs over a number of super powered adversaries, starting with 'The Juggernut' in "Not Brand Echh" #5. All of his victories are purely accidental; lacking superhuman powers, dumb luck plays a major role in all his adventures.
