Los Vengadores #12

In "Noches de Wundagore," the Avengers face a dark turning point when Scarlet Witch is transformed into Chthon, a malevolent entity, during a clash with Modred the Mystic. With her identity and her bond to their presumed father, Django Maximoff, thrown into chaos, Mercury rushes to warn the team—just as the line between protector and threat begins to blur. Written by David Michelinie and Luis Ferrado, with dynamic art by John Byrne and cover by Byrne and Terry Austin, this 1984 issue marks a pivotal moment in the team's history.
