What Season 3 of What If...?
Season three of What If...? picks up the multiverse opened at the end of Loki's first season. Narrated by Jeffrey Wright, the Watcher travels through timelines where a twist in the past alters the course of the Marvel Cinematic Universe. Each episode starts from a different decision. Hulk faces a new team of Avengers Mech Suits, Agatha Harkness, a Hollywood star, co-stars Howard Stark in her feature directorial debut, and the Red Guardian interferes with the Winter Soldier's mission. Howard the Duck and Darcy Lewis run into dangerous factions, Riri Williams tries to overthrow Quentin Beck, and Shang-Chi and Kate Bishop cross into a Wild West where The Hood threatens innocent people. Many actors reprise their roles, though the tone ranges from dark to light.
