Steeljacket

Bursting onto the Gotham scene in 1995's Robin #13 — courtesy of the sharp creative team of Chuck Dixon, John Cleary, and Phil Jimenez — Steeljacket is a Modern Age DC villain who carved out a niche in the darker corners of Batman's world. With appearances spread across Robin, Batman: Gotham Knights, and Batman: Prodigal, this character moves in seriously elite company, sharing pages with Robin, Nightwing, Batman, and Bruce Wayne himself. A rare find with only four catalogued appearances, Steeljacket is exactly the kind of deep-cut Gotham antagonist that dedicated collectors love to track down — a vivid reminder of the rich, layered rogues' gallery that defined DC's Batman titles in the mid-to-late '90s.
