The Iron Man 4: New Chapter teaser trailer begins with an emotional montage highlighting the legacy Tony Stark (Robert Downey Jr.) left behind. Iconic moments from previous films flash by, including his heroic sacrifice in the final battle of Avengers: Endgame, still deeply resonating. Tony Stark’s unmistakable voiceover plays: “Part of the journey is the end… but sometimes, the end is just the beginning.”

As the screen fades to black, the scene transitions to present-day New York. Harley Keener (Ty Simpkins), the boy from Iron Man 3, now grown and highly skilled in technology, is seen working in Tony’s lab. He has taken on Stark’s mantle of innovation, crafting a new suit of armor inspired by Tony’s designs, but with his own modern twist. Harley’s journey is one of honoring Stark’s legacy, grappling with responsibility, and dealing with the immense pressure of living up to the Iron Man name.

The trailer cuts to a boardroom where Pepper Potts (Gwyneth Paltrow) and Happy Hogan (Jon Favreau) discuss the rise of new technological threats. A shadowy corporation, “The Infinite Arc,” has been experimenting with unstable Stark technology. Pepper expresses concern about the danger of this tech falling into the wrong hands. Quick cuts show global chaos: drones attacking cities, malfunctioning advanced AI systems, and mysterious armored figures terrorizing civilians.

The villain is soon revealed—Ezekiel Stane (possibly played by Austin Butler), the son of the late Obadiah Stane, has perfected his father’s designs and seeks revenge on the Stark legacy using advanced weapons and suits. Cold and calculating, Ezekiel has developed his own version of the Iron Man suit, superior in strength and power.

The action intensifies as Harley dons his new Iron Man suit, sleek and futuristic, equipped with enhanced AI and weaponry. High-speed aerial combat, intense firefights, and Harley’s youthful energy take center stage as he fights to find his place in the Iron Man legacy.

In the final moments, Harley lands in front of a memorial to Tony Stark, his helmet retracts, and he softly says, “I hope I’m making you proud.” The trailer concludes with the title Iron Man 4: New Chapter, followed by the tagline: “The legacy continues.”

The teaser promises a powerful blend of emotion, action, and the dawn of a new era for Iron Man, with the stakes higher than ever.
