Natalia Romanova

A creature of the modern Marvel era, Natalia Romanova stepped onto the page in 2003 through Trevor Hairsine's Ultimate Six and has kept remarkably sharp company ever since — sharing adventures with the likes of Steve Rogers, Logan, Peter Parker, and Spider-Man across titles like Ultimate Wolverine, Ultimate Six, and Ultimate Spider-Man. Her 25 catalogued appearances stretch all the way to 2026, a quiet testament to staying power in Marvel's Ultimate universe. She's the kind of figure whose presence in those landmark early-2000s stories makes her worth tracking down for any serious Modern Age collector.
