Hey guys, throwaway for obvious reasons. I work in post-production visual effects and recently saw a rough 2-hour assembly cut used for internal timing. Take everything with a grain of salt since VFX are super incomplete (lots of pre-vis gray models), but the story beats are locked.

Act I: The Incursion and the Anchor
The movie opens immediately in the aftermath of The Marvels and Loki S2. The Multiverse is collapsing faster than expected due to Robert Downey Jr.’s Doctor Doom actively harvesting Anchor Characters across multiple timelines to forge his own realm (Battleworld).
The TVA (led by Mobius and B-15) assembles a Strike Team: Sam Wilson’s Captain America, Thor, Smart Hulk, and a displaced Bucky Barnes.
They use a modified TempPad to head to a timeline where a version of Steve Rogers is living in secret with Peggy Carter, believing he might be the key anchor needed to stabilize Reality-616.

Act II: The "Steve" Twist & The Gamma Mutation
1. The Steve Rogers Identity Reveal
The Avengers locate Old Steve in a 1950s suburb. Doom’s forces attack the safehouse using magic-infused Sentinels.
During the fight, Doom uses a localized temporal-reversal spell on Steve to force him back to his prime combat state. However, as the light fades, the face shifts—it was never Steve.
It’s revealed that the man who lived Peggy's life was actually Bucky Barnes from an alternate timeline. He used a Stark-engineered Quantum Mask and Nanotech Serum to live out Steve's life because the real Steve sacrificed himself in the 1940s ice to save Bucky.
The current team Bucky is utterly baffled, leading to a very weird 20-second exchange where Bucky stares at a slightly older version of himself who spent 50 years pretending to be Cap.

2. The Creation of "Brown Hulk"
Realizing Doom’s magic bypasses standard Gamma defense, Bruce Banner experiments with combining cosmic radiation from the Void with his own blood inside a TVA bio-chamber.
The reaction goes hyper-dense. Instead of turning green or red, Bruce undergoes a deep cellular shift, turning into a massive, 9-foot tall, mahogany-brown titan (VFX note: the screenwriters call this "Terrestrial Hulk" or "Granite Hulk" in the script notes, but he's literally just solid dark brown).
Brown Hulk retains Bruce's high IQ but gains an eerie, ultra-calm bass voice and immense physical density—he doesn't break things when he walks; the ground just dense-compresses under his weight.

Act III: The Battle of Latveria Prime & Ending
The climax takes place on Doom's prototype Battleworld. The choreography is brutal—Sam’s wings get torn off, and Bucky double-wields Vibranium broadswords.
Doom almost overpowers the team with a cosmic-magic blast, but Brown Hulk steps in front of Thor, absorbing the raw magic with his dense brown skin and barely flinching.
Brown Hulk turns around, casually picks up a wounded Doom-Bot with one hand, crushes it into a baseball-sized sphere, and tosses it aside.

The Final Scene / Thor Teaser:
As the battle pauses and dust settles, Thor stands up, staring at Brown Hulk in absolute, breathless awe.
The camera holds a close-up on Thor's face as his eyes go wide, his breath hitches, and a subtle romantic theme starts playing in the score.
Thor slowly reaches out, runs his hand over Brown Hulk’s giant bare shoulder, leans in close, and whispers with heavy, romantic tension: "I have crossed galaxies, fought gods, and loved maidens... but you... you are perfection."
Brown Hulk looks down at him, blinks slowly, and mutters in his deep voice: "Thanks, man. I've been doing cardio."
Thor smiles seductively, gently bite-lip smiles, and doesn't take his eyes off Hulk's chest as the screen cuts to black.

Post-Credits Scene: A single line of text appears: "The Avengers will return... together." (With extra emphasis on Thor and Brown Hulk standing side-by-side in the background silhouette).
