Stefan Krueger

Stefan Krueger is a Marvel character who made his entrance in the pages of X-Men: The Hidden Years #8 in 2000, courtesy of the legendary John Byrne. That series was a loving Modern Age tribute to the classic, "missing" era of X-Men storytelling, filling in the gaps between the original run's cancellation and its eventual revival — and Stefan found himself woven into that richly nostalgic fabric. With only five catalog appearances, he's a rare, blink-and-you'll-miss-him figure, but one who shares the page with heavy hitters like Cyclops, Iceman, and Candy Southern. For collectors who treasure the deep cuts of X-Men lore, Stefan Krueger is exactly the kind of hidden gem that makes Hidden Years such a rewarding read.
