Mary Brown

A quiet but genuine piece of Marvel's Copper Age tapestry, Mary Brown made her debut in Captain America #390 in 1991, brought to life by the celebrated creative team of Mark Gruenwald and Rik Levins. Her handful of appearances stretch across a surprisingly broad span — touching Marvel history all the way from 1991 to 2011 — and she keeps genuinely colorful company, sharing pages with the likes of Karisma, Knockout, Anaconda, and Machinesmith. Rare in the catalog but real, she's the kind of character that rewards the dedicated Marvel completist who loves discovering the full, richly populated world behind the iconic shield.
