Neptunus

A creature of the Bronze Age deep, Neptunus surfaced in the pages of The Incredible Hulk #251 in 1980, brought to life by the celebrated creative team of Bill Mantlo and Sal Buscema. This rare Marvel figure shares their corner of the universe with an eclectic cast — Siren, Woodgod, Viperus, and the gamma-powered Doc Samson among them — making for some genuinely wild Bronze Age company. With only a handful of catalog appearances, Neptunus is the kind of obscure gem that reminds devoted collectors just how imaginatively strange the House of Ideas could get during that fertile era.
