Marvel's cinematic universe has struggled with inconsistent reception since Avengers: Endgame, but the forthcoming Avengers: Doomsday appears designed to reverse this trajectory. The film brings together multiple hero factions—the X-Men, Fantastic Four, and New Avengers—rallying under Thor to confront Doctor Doom, with Robert Downey Jr. reprising his role in a casting that, while initially met with scepticism, shows promise in newly released footage.

Essential preparation for the film requires viewers to watch the Loki Disney+ series, as the God of Mischief represents a crucial plot element in the ensemble story. Though Loki appeared to die heroically in Infinity War whilst attempting to stop Thanos, Endgame established his survival, positioning him for a significant presence in the upcoming Doomsday narrative.
