X-Men: The Asgardian Wars

In 1989, Marvel's "X-Men: The Asgardian Wars" brought Chris Claremont's mythic storytelling together with Arthur Adams' lush, intricate artwork for a single-issue crossover that pitted the X-Men against threats rooted in Asgardian lore. This one-shot distilled the epic scale of Claremont's long-running X-Men saga, blending mutant drama with Norse mythology in a self-contained tale that showcased the team's versatility beyond their usual battles. Though brief, it remains a notable artifact of the late-80s X-Men era, highlighting the creative synergy between two of the franchise's most celebrated talents.
