Avengers 6: Secret Wars (2025) begins with the multiverse collapsing due to the actions of powerful forces, most notably Kang the Conqueror, and other cosmic entities. As the fabric of reality begins to tear, different universes start merging, causing chaos across dimensions. This catastrophic event, known as “Secret Wars,” brings together heroes and villains from countless realities. Familiar faces from multiple universes, including alternate versions of the Avengers, come into conflict as the fate of all existence is put into jeopardy. The Avengers must assemble like never before, but the threat they face is unlike anything they’ve encountered, with the multiverse itself unraveling around them.
In response to the multiverse’s collapse, the villainous Doctor Doom seizes the opportunity to manipulate the chaos and creates a new, fragmented reality known as “Battleworld.” Battleworld consists of pieces from various universes, making it a chaotic battlefield where heroes and villains from across time and space must fight for dominance. The Avengers, along with alternate versions of characters like Spider-Man, the X-Men, and others, are forced to battle for control of Battleworld, while facing the relentless threat posed by Doom. As the battle intensifies, alliances shift, and new alliances are forged in the face of the growing cosmic threat, revealing the true extent of Doom’s power.
The climactic showdown sees the Avengers and their multiversal allies uniting to take down Doctor Doom and restore balance to the multiverse. In a final, desperate battle, the heroes confront Doom in an effort to undo the damage and prevent total destruction. The resolution of this conflict leads to significant changes within the Marvel Universe, with new realities being established and some characters permanently altered. Although the multiverse is saved, the events of Secret Wars leave lasting consequences, setting the stage for future Marvel stories. The film concludes with a sense of hope, but also with lingering questions about what comes next for the Avengers and the new universe they’ve helped shape.
