The screen fades from black to a devastated landscape. Smoke billows from the ruins of a city. The camera pans over destroyed buildings and deserted streets, with haunting silence filling the air. A deep, foreboding voice begins to narrate.

Narrator: “In a world broken by conflict and betrayal…”

Cut to: A close-up of Bruce Banner (Mark Ruffalo) looking weary and determined, walking through the rubble. His eyes glow faintly green.

Narrator: “…a hero cast aside…”

Cut to: A flashback of Bruce Banner transforming into the Hulk, fighting alongside the Avengers, then being blasted into space.

Narrator: “…will return for vengeance.”

Cut to: A distant planet, Sakaar. Gladiator Hulk (Mark Ruffalo) stands victorious in an arena, surrounded by cheering alien spectators. His eyes burn with rage.

Voiceover: “They thought they could banish me… They were wrong.”

Quick cuts:

• Bruce Banner (Mark Ruffalo) and Edward Norton (as an alternate universe Bruce Banner) standing face-to-face, the tension palpable.
• Thor (Chris Hemsworth) wielding Stormbreaker, preparing for battle.
• Doctor Strange (Benedict Cumberbatch) casting a complex spell, his eyes wide with concern.
• Black Widow (Scarlett Johansson) in a moment of silence, staring at a photograph of Bruce.

Cut to: The Hulk, now wearing advanced gladiator armor, roaring as he leaps into battle. Explosions and chaos ensue.
