Manhunter

A Modern Age arrival stepping onto the scene in 2004's Robin #127 — courtesy of creators Bill Willingham and Damion Scott — this Manhunter has carved out a distinct corner of the DC Universe across a publishing history stretching all the way to 2020. With appearances spread across titles like Manhunter, Batman: Battle for the Cowl Companion, and Batman Arkham: Victor Zsasz, this character moves through some genuinely gritty, street-level Gotham territory, sharing pages with heavyweights like Batman, Robin, Green Lantern, Barbara Gordon, and Kate Spencer. Eighteen catalog appearances may keep this one in the "deep cut" category, but for collectors who love hunting down the full texture of the Modern Age DC tapestry, that's precisely the kind of discovery that makes the chase worthwhile.
