Zack Galvin

Peter David has always had a gift for populating his Marvel runs with characters who linger in the memory, and Zack Galvin — debuting in The Incredible Hulk #390 in 1992 courtesy of David and artist Dale Keown — is a quiet testament to that talent. Emerging in the Copper/Modern Age, Zack carries the rare distinction of belonging to both the Pantheon and X-Factor, two of David's most celebrated ensemble casts, which means his adventures unfold alongside a genuinely impressive roster that includes Quicksilver, Lorna Dane, Strong Guy, and Val Cooper. His appearances are spread across nearly three decades (1992–2021), a span that speaks to a stubborn staying power well beyond what raw issue counts might suggest. For collectors diving deep into Peter David's interconnected Marvel universe — particularly through those landmark omnibus editions — Zack Galvin is exactly the kind of find that rewards the thorough reader.
