X-Men #36

Published by Marvel Comics in September 1967, X-Men #36 stands as a notable entry in the original Silver Age run of the series. During this period, the creative team was navigating a transitional era for the mutant team, as the title struggled to maintain the high sales figures enjoyed by other Marvel properties like The Fantastic Four or Spider-Man. The issue was written by Roy Thomas and featured pencils by Werner Roth, working under the pseudonym Jay Gavin, with inks provided by John Tartaglione.

The narrative follows the team as they encounter the Factor Three organization, a recurring antagonist group that played a significant role in the series during the mid-sixties. The cover and interior art reflect the distinct house style of the era, emphasizing the grounded, somewhat melodramatic character dynamics that defined the X-Men before their late-seventies revitalization. While not widely considered a landmark issue in terms of plot, it remains a characteristic example of the effort to build a persistent, serialized mythology for Marvel's outcasts during a time when the series faced recurring cancellation threats.
