The X-Men #23

Published in August 1966, The X-Men #23 was part of the original Silver Age run of the series, created during the partnership between writer Roy Thomas and artist Werner Roth. This issue serves as a mid-run entry that continued to develop the group's dynamic under the direction of Professor X, featuring the debut of the Locust as an antagonist. The story was rooted in the era's fascination with science-gone-wrong tropes, which were a hallmark of early Marvel storytelling.

The visual direction by Werner Roth, who often worked under the pseudonym Jay Gavin, reflected the transition away from the heavy Jack Kirby influence toward a cleaner, more fluid illustrative style that defined the mid-1960s X-Men. While this period of the series is often viewed by historians as a time of searching for a definitive identity prior to the title's shift to reprints, it remains a significant touchstone for collectors interested in the evolution of mutant lore and the creative experimentation that sustained the series during its formative years.
