Mayday Parker
Mayday Parker is the infant daughter of Peter Parker (Spider-Man) and Mary Jane Watson, first glimpsed in an alternate-timeline story. Her birth set the stage for her eventual role as Spider-Girl, carrying on her father's heroic legacy.
Few characters have earned their own legacy quite like Mayday Parker, who swung onto the scene in 1998's What If...? #105 — a what-if premise that proved so compelling, creators Tom DeFalco and Ron Frenz spun it into a franchise that has endured for over two decades. A Marvel Modern Age original, she anchored her own long-running titles in Spider-Girl and Amazing Spider-Girl, sharing pages with the likes of Peter Parker, Mary Jane Watson-Parker, and Spider-Woman along the way. With 35 catalog appearances, two collector-recognized key issues, and a publishing history stretching from 1998 to 2023, Mayday is living proof that a fresh take on a beloved corner of the Marvel universe can carve out something genuinely its own. For fans who love legacy storytelling done with heart, she's absolutely worth your shelf space.
