The X-Men #123

The X-Men issue #123, published in July 1979, emerged during the influential creative run of writer Chris Claremont and artist John Byrne. This period is widely regarded as a high point in the title's history, characterized by the team's evolution into a more sophisticated, global ensemble cast. The issue itself serves as a chapter in the Proteus saga, a narrative arc celebrated for its psychological depth and the introduction of a formidable, reality-warping antagonist who challenged the team on both a physical and emotional level.

The artistic direction by John Byrne, coupled with Terry Austin's clean, detailed inks, established a visual standard for the series that remains iconic. Byrne sought to provide a cinematic sense of scale and nuanced character expression that separated the book from its Silver Age origins. Upon release, the issue was well-received by readers for its tight pacing and the way it grounded the team's interpersonal dynamics within the high-stakes conflict, solidifying the 'All-New, All-Different' X-Men as a cultural cornerstone for Marvel Comics.
