What If?
Marvel's What If? (1977–1984) invited readers to explore alternate timelines where pivotal moments in the Marvel Universe turned out differently—often with catastrophic or wildly unexpected results. Narrated by the cosmic observer Uatu the Watcher, each of the 47 issues reimagined classic stories, from a Spider-Man who joined the Fantastic Four to a Thor who became a herald of Galactus. The series was a playground for writers like Roy Thomas, Don Glut, and Peter B. Gillis, alongside artists Ron Wilson, Alan Kupperberg, and Sal Buscema, who brought these "what if" scenarios to life with a mix of tragedy, humor, and high-stakes drama. It remains a cornerstone of Marvel's multiverse, proving that even the smallest change could ripple into a universe of new possibilities.
