Interest was rekindled with 1975s Giant-Size X-Men and the debut of a new, initially published bi-monthly, it became a monthly with issue #14. The series was placed firmly in the Marvel Universe, with guest appearances by Namor in #6, the jungle adventure hero Ka-Zar and the Savage Land were introduced in issue #10.

Byrne plotted the story wanting to depict the Sentinels as a threat to the existence of the mutant race. Mystiques Brotherhood changed sides and became the government-backed Freedom Force in #199 and their first action was to capture Magneto, who had begun associating with the X-Men during the Secret Wars II crossover.
