Doctor Hugo Strange

A sinister presence lurking at the edges of Gotham's darkest corners, Doctor Hugo Strange made his Modern Age catalog debut in the delightfully retro Batman '66 Meets the Man from U.N.C.L.E. #1 in 2016, brought to life by writer Jeff Parker and artist David Hahn. His appearances span some genuinely compelling DC territory — from the monster-haunted streets of Batman: Night of the Monster Men to the celebrated Batman by Tom King run — keeping rarefied company with Batman, Bruce Wayne, Dick Grayson, and Alfred Pennyworth along the way. With only ten catalog appearances, he's a rare find for the dedicated Bat-completist, the kind of deep-cut villain whose every showing carries real weight.
