Uncanny X-Men #36

Uncanny X-Men #36 was published in September 1967 during the title's original Silver Age run. Written by Roy Thomas with iconic pencils by Werner Roth, the issue serves as a transition point for the team, centering on the battle against the Factor Three organization. It reflects the experimental tone of the series during the mid-sixties as the creators attempted to raise the stakes for the adolescent mutants while navigating the constraints of the Comics Code Authority.

The cover art and interior work embody the aesthetic transition of the X-Men franchise before Jim Steranko and Neal Adams would later redefine its visual language. While the issue was not considered a breakout success at the time of its release, it is now viewed as a representative artifact of the late-sixties narrative style, characterized by a mix of Cold War-era espionage tropes and traditional superhero team dynamics that defined Marvel's output under Stan Lee’s editorial tenure.
