Boss Maroni

Boss Maroni is a Gotham City mob boss and fixture of the city's criminal underworld. He is best known in DC lore as the gangster who threw acid at Harvey Dent, transforming the district attorney into the villain Two-Face.

Gotham's underworld has always needed its villains, and Boss Maroni is one of those shadowy crime figures who casts a long shadow across DC's darker corners. Debuting in Batman #410 in 1987 — a creative collaboration between Max Collins and Dave Cockrum right in the heart of the Copper Age — this mob boss has proven surprisingly durable, surfacing across nearly four decades of Gotham storytelling. Maroni keeps genuinely elite company, sharing pages with Batman, Bruce Wayne, Dick Grayson, Robin, and Batgirl across titles like Nightwing and Batman, which says everything about the caliber of the world he inhabits. A lean appearance count makes every showing count — this is a character for readers who love the crime-boss texture that gives Gotham its grit.
