Baroness Zemo

A figure of aristocratic menace who stepped onto the Marvel stage in 1994, Baroness Zemo made her debut in the pages of Captain America — one of Marvel's most storied titles — courtesy of the sharp creative team of Mark Gruenwald and Dave Hoover. Her very name places her in the shadow of one of Captain America's most legendary rivalries, and she shares those pages with the Star-Spangled Avenger himself alongside the likes of Helmut Zemo and Heike Zemo. Rare appearances can carry an outsized mystique, and for readers who love digging into the deeper corners of Cap's world, she's a tantalizing piece of early Modern Age history worth tracking down.
