The Multiverse is dying. Following the events of Avengers: The Kang Dynasty, the boundaries between universes are collapsing. Countless realities are colliding in catastrophic Incursions, and entire worlds are being erased. Kang the Conqueror, defeated but not destroyed, has left behind something worse—a chain reaction of universe-ending events. Amid the chaos, the last surviving universes are drawn into a final battleground: a patchwork planet called Battleworld, created and ruled by a mysterious godlike figure—Doctor Doom, who has stolen power from the Beyonders to preserve fragments of the multiverse and crown himself as God Emperor Doom. Here, variants of Marvel heroes and villains from every corner of the multiverse—different versions of Iron Man, Spider-Man, Wolverine, Black Panther, Captain Marvel, and more—exist in uneasy coexistence. The few remaining heroes of the main MCU universe (Earth-616), including Doctor Strange, Spider-Man (Tom Holland), and a surviving group of Avengers, must form a final resistance. They discover that the key to restoring the multiverse lies with a reborn Reed Richards (Mr. Fantastic) and a powerful artifact hidden within Doom’s fortress—the remains of the original Reality Loom, once protected by the TVA. In an epic war across reality, factions of heroes and villains battle not just for survival, but for the right to rewrite existence. Sacrifices are made, legacies are passed, and universes fall. But in the final act, a new Avengers team rises—blending legacy characters (like Shuri’s Black Panther, Sam Wilson’s Captain America, and Kate Bishop’s Hawkeye) with multiversal icons (such as Hugh Jackman’s Wolverine and Tobey Maguire’s Spider-Man). Together, they face Doom in a cosmic showdown to decide the fate of everything.
