Marsha Rosenberg

Marsha Rosenberg made her entrance in one of Marvel's most ambitious Bronze Age events — Secret Wars #3 in 1984, brought to life by the legendary team of Jim Shooter and Mike Zeck. A member of the Fantastic Four, she's been part of some genuinely collector-significant moments, with three key issues to her name and a publishing history that stretches an remarkable four decades, from that landmark crossover all the way to 2026. She shares the page with titans like Captain America, Reed Richards, and Ben Grimm himself, placing her squarely at the heart of Marvel's biggest stories — and if you're building out your Secret Wars collection, Marsha Rosenberg is absolutely a name worth knowing.
