Marvel has thrived on the multiverse for some time, with comic book runs and films set across different timelines. Since its debut in 2021, Marvel's animated series What If...? created a format where Marvel's greatest heroes and villains are free to explore realms and universes unbound by the conventions of the MCU canon. This year, just in time for the holidays, Marvel's What If...? is back for its second season, ringing in the season of hope and good wishes with two action-packed tales of goodwill. Premiering on Disney+ starting December 22nd and airing a new episode every night over nine nights, What If...? Season Two is a great holiday treat for Marvel fans.
