The teaser trailer for Iron Man 4: New Chapter (2025) from Marvel Studios sends fans into a frenzy, marking the long-awaited return of Iron Man’s legacy. Though Tony Stark may be gone, his influence still looms large over the Marvel Cinematic Universe (MCU), and a new hero steps up to wear the armor in this thrilling next chapter.
The trailer opens with a hauntingly familiar sound: the echo of hammering metal. In a dark workshop, illuminated by the faint glow of arc reactors, we catch glimpses of blueprints and armor parts scattered around. A voiceover, unmistakably the voice of Tony Stark (Robert Downey Jr.), plays in a recording: “If you’re listening to this, the world is going to need Iron Man again.”
The camera pans to Riri Williams (Dominique Thorne), the young genius introduced in Black Panther: Wakanda Forever, tinkering with her own version of the Iron Man suit. Known in the comics as Ironheart, Riri is poised to take on the mantle in Iron Man 4, and the trailer wastes no time showing her potential. “I didn’t ask for this,” she says, as sparks fly from her welding tools. “But someone has to carry on his legacy.”
Quick flashes follow of Riri testing the suit, flying through the night sky with ease, though not without some turbulence. Her initial flight feels familiar, reminiscent of Tony Stark’s early days as Iron Man. A shot of her landing hard on the ground, the suit crackling with energy, reveals that this isn’t just about flashy tech. Riri is still learning, and the stakes are higher than ever.
Cut to scenes of chaos—explosions in major cities, and a new villain stepping into the spotlight: Ezekiel Stane (rumored to be played by Timothée Chalamet), the son of Tony Stark’s old nemesis, Obadiah Stane. His goal? To tear down Tony Stark’s legacy, using advanced technology to create a fleet of destructive drones. Stane’s chilling words ring out: “Iron Man wasn’t a hero. He was a weapon. And now, I’ll finish what my father started.”
As the tension builds, we see familiar faces returning to guide Riri on her journey. James “Rhodey” Rhodes (Don Cheadle), now fully recovered from his injuries, takes on a mentor role, appearing in several scenes as War Machine, providing Riri with wisdom and warnings: “This life isn’t easy. You’ll need more than armor to survive it.”
The trailer also teases the introduction of new tech, with Riri’s Ironheart suit featuring cutting-edge innovations inspired by Tony Stark’s work, but with her own twist. A brief glimpse of a high-stakes battle showcases Ironheart facing off against Stane’s drones in the skies above New York City, with heart-pounding aerial maneuvers and energy blasts lighting up the night.
The final moments of the teaser show Riri, fully suited as Ironheart, standing in front of a holographic image of Tony Stark’s first Iron Man suit. The legacy is clear, but so is the message: “I’m not him,” Riri says, her helmet retracting. “But I’ll fight for what he stood for.”
The teaser ends with the title Iron Man 4: New Chapter appearing on the screen, followed by the tagline: “The legacy continues.”
This thrilling trailer sets up a powerful, emotional, and action-packed story of legacy, responsibility, and the evolution of the Iron Man mantle as Riri Williams steps into a role that will challenge her like never before.
