Amphibian

Debuting in Marvel Age Annual #1 in 1985, Amphibian is a Bronze Age Marvel creation born from a remarkable collaborative effort between Jim Shooter, Kurt Busiek, James Fry, and Al Milgrom — serious pedigree for a character who has quietly endured across nearly four decades of comics history. Most at home in the pages of Supreme Power and Squadron Supreme, Amphibian keeps rarefied company alongside the likes of Hyperion, Doctor Spectrum, and Stanley Stewart, placing this character firmly within one of Marvel's most compelling corners of super-powered storytelling. With 32 catalogued appearances, three of them collector-recognized key issues, and a publishing span stretching all the way to 2023, Amphibian is a rewarding discovery for anyone digging deeper into Marvel's rich alternate-universe landscape — a figure whose longevity speaks for itself.
