Frog-Man

Bounding out of the Bronze Age in 1982, Frog-Man is one of Marvel's most endearingly offbeat characters — a creation of J. M. DeMatteis and Kerry Gammill whose longevity across 44 years proves that even the quirkiest corners of the Marvel Universe have a devoted following. With two key collector issues to their name and appearances spanning titles as varied as Punisher War Journal, Iron Man, and Fear Itself: Youth in Revolt, this amphibious oddity has hopped through some surprisingly high-profile company, sharing pages with Spider-Man, Captain America, Iron Man, and Peter Parker himself. It's a testament to the character's staying power that what began as a Bronze Age curiosity is still turning up in Marvel's pages well into the 2020s — and for collectors who love the weird, wonderful fringes of the House of Ideas, Frog-Man is absolutely worth tracking down.
