The X-Men #100

Published in August 1976, The X-Men #100 marks a significant milestone in comic book history, serving as the climax of the 'X-Men' revival under writer Chris Claremont and artist Dave Cockrum. This issue concludes the 'Duel of the X-Men' storyline, which pits the new team of mutants against their predecessors, the original five X-Men, who are actually revealed to be androids controlled by the villainous Steven Lang. It represents a pivotal moment in the transition of the series from its mid-seventies soft reboot toward the character-driven, soap-opera style that would define the franchise for decades.

The artistic direction by Dave Cockrum was instrumental in establishing the visual identity of the modern X-Men. His designs for the new roster—including Storm, Nightcrawler, and Colossus—offered a more dynamic and international aesthetic compared to the original 1960s lineup. The issue is widely regarded by collectors and critics as a bridge between the cancellation-threatened era of the late sixties and the massive commercial success the series would achieve in the 1980s. Its status as a centennial issue makes it a sought-after piece for those tracking the structural evolution of the Marvel Universe.
