Leonard Snart

Few villains have left as cool a mark on the Silver Age as Leonard Snart, who first stepped onto the scene in Showcase #8 in 1957, conjured by the legendary creative partnership of John Broome and Carmine Infantino. Over nearly seven decades — a remarkable 1957 to 2026 run — Snart has remained one of DC's most enduring antagonists, a fixture across Flash and The Flash titles and even earning a place in Who's Who: The Definitive Directory of the DC Universe, the ultimate stamp of DC canon significance. He shares the pages with titans like Barry Allen, Wally West, and even Batman himself, and with two key collector issues to his name, his footprint in comics history is as undeniable as it is cool. If you love the Flash's rogues' gallery, Leonard Snart is absolutely essential reading.
