What If...? (Season 3)
"One question changes everything."
Taking inspiration from the comic books of the same name, each episode of this animated anthology series questions, revisits and twists classic Marvel Cinematic moments.
Peggy Carter's story is finally concluded. Tony appears across realities. The Watcher's role in the multiverse war grows. The last anthology chapter — directly precedes Doomsday.
Why It Matters in the MCU
The animated anthology format allows Marvel's first animated Disney+ series to explore the franchise's own mythology with a freedom that live-action constraints prevent — from a Nazi-defeating Peggy Carter to a T'Challa who became Star-Lord to a Doctor Strange who destroyed his own timeline out of grief. The series is strongest when it uses the premise to deepen understanding of established characters rather than simply to produce spectacle, and Strange Supreme is the most emotionally effective story across all three seasons. Its interconnected finale structure demonstrates how the What If format can generate genuine dramatic stakes from apparently standalone episodes.
