Marvel’s epic finale to Phase Six and The Multiverse Saga, Avengers: Secret Wars brings together heroes and villains across realities in an all‑out battle against Doctor Doom’s ultimate plan. As multiple universes begin to collapse due to catastrophic incursions, Doom constructs a reality‑mash called Battleworld—where he reigns supreme. Key heroes—including the Avengers, X‑Men, and the Fantastic Four—must unite to breach Doom’s citadel and stop him from reshaping existence with the immense power of Franklin Richards, who may serve as Doom’s cosmic engine. The team executes a daring final assault on Doom’s fortress. Despite casualties—including variants like a dark Captain America and alternate Loki—protection spells by Doctor Strange help shield the surviving heroes. Ultimately, they confront Doom in a climactic showdown to restore the multiverse and prevent permanent collapse into Battleworld.
