Powerhouse

Burst onto the scene in 1991's The New Warriors Annual #1 — courtesy of the creative team of Fabian Nicieza and Mark Bagley — Powerhouse is a Copper Age Marvel creation who made an immediate impression by sharing pages with some of the House of Ideas' heaviest hitters, including Nova, Spider-Man, and Captain America. Though their catalog footprint is compact, the character's appearances span a remarkable 23 years and include at least one collector-significant key issue, a testament to their staying power in Marvel's cosmic and heroic corners. Fans of Nova's world in particular will want to track this one down.
