Harlan Kleinstock

Harlan Kleinstock arrived in the pages of Uncanny X-Men #298 in 1993, a creation of Scott Lobdell and Brandon Peterson that planted its roots firmly in Marvel's fertile Copper/Modern Age soil. A member of the X-Men with a presence stretching remarkably across nearly three decades, Harlan is one of those characters whose longevity quietly speaks for itself — turning up in X-Men, Uncanny X-Men, and Magneto: Dark Seduction alongside a compelling roster that includes Sven Kleinstock, Joanna Cargill, Amelia Voght, Magneto, and Colossus. With 19 catalog appearances spread across 28 years, he's a deep-cut figure who rewards the dedicated collector willing to dig into the layered, morally complex storytelling that defined Marvel's mutant corner of the '90s and beyond.
