What If

What If...? launched in 1977 as a comic book anthology that let writers rewrite history. Instead of following the main Marvel continuity, these stories ask what happens when key moments go wrong or right. A hero might fall, a villain could win, or an entire world changes because one choice shifted. The series ran for 14 volumes and many stand-alone issues over decades, giving fans a playground to explore alternate realities without breaking canon.[edit]
