Justice League of America #33

In "Enemy from the Timeless World!", the Justice League of America faces a chilling divide when a mysterious force from the future exploits their powers to battle the alien menace Alien-Ator—only for the alien to awaken awareness of the League itself and twist their unity into conflict. Written by Gardner Fox and brought to life by Mike Sekowsky’s dynamic art, with Bernard Sachs’ inks and Gaspar Saladino’s lettering, this 1965 classic sees the team fractured from within. The cover, penciled by Sekowsky and inked by Murphy Anderson, captures the moment of tension with striking precision.
