Powerhouse

Bursting onto the scene in 1981's Rom #24 — courtesy of the creative powerhouse team of Bill Mantlo, Mark Gruenwald, Sal Buscema, and Joe Sinnott — Powerhouse is a Bronze Age Marvel creation with some seriously impressive company on their résumé. Though their catalog footprint is compact, the pages they inhabit are anything but modest, sharing adventures with the likes of Spider-Man, Mr. Fantastic, Ororo Munroe, and Alex Power across titles including Rom and Venom: The Hunted. That debut issue carries collector-significant key status, making it a worthy addition to any Bronze Age pull list, and the character's appearances stretching across more than four decades speak to a quiet staying power that dedicated Marvel hunters will appreciate.
