Detective Flass

Corrupt from the first panel he ever darkened, Detective Flass made his debut in the landmark Batman #404 (1987), stepping onto the page courtesy of the legendary creative team of Frank Miller and David Mazzucchelli. He emerged during one of DC's most celebrated storytelling eras, embedded in a Gotham populated by icons like Lieutenant James Gordon, Commissioner Gillian Loeb, Harvey Dent, and Batman himself — company that signals just how significant his corner of the DC universe is. Though his catalog footprint is small, Flass carries the weight of a character born in a genuinely essential run, the kind of debut issue that collectors and readers return to again and again.
