Carolyn Trainer

Carolyn Trainer stepped onto the Marvel stage in 2004's Spider-Girl #68, courtesy of the celebrated creative team of Tom DeFalco, Ron Frenz, and Pat Olliffe, and she's been a fixture of the Modern Age ever since — racking up 43 catalog appearances across titles as varied as The Amazing Spider-Man, Spider-Girl, and Sinister War over an impressive two-decade run. She moves in genuinely dangerous company, sharing pages with the likes of Spider-Man, Peter Parker, Electro, Lady Octopus, and Francine Frye, which tells you everything about the high-stakes corner of the Marvel Universe she inhabits. With at least one key-issue appearance to her name and a publishing history that stretches all the way to 2026, Carolyn Trainer is the kind of character who rewards the dedicated reader willing to dig into Marvel's rich spider-adjacent mythology — a modern creation with real staying power.
