When Does Marvel’s What If…? Come Out?

What If…? is a Marvel animated series that explores alternative timelines of the Marvel Cinematic Universe. It’s the fourth streaming series to launch as part of the MCU’s Phase 4 and features many of the characters and cast from the movies.

What If…? has a long history. The new show is based on the comic series of the same name, which has been published since 1977. Over 40 years, the original run reimagined significant events in Marvel comics history, including what would have happened if someone other than Peter Parker had become Spider-Man, or how the world would change if Ultron never existed. Like the animated show, the first comic series was narrated by a Watcher, one of the powerful aliens observing the Marvel multiverse.
