*Iron Man 4: New Chapter* reignites the iconic Marvel hero’s story, exploring a fresh chapter where Tony Stark’s legacy endures through new faces, advanced technology, and an evolving world in need of protection. While Tony Stark’s (Robert Downey Jr.) death in *Avengers: Endgame* left a void, *Iron Man 4* introduces new characters who step up to honor his legacy, grapple with his technological genius, and navigate the moral complexities of wielding Stark’s innovations.

At the film’s center is Riri Williams (Dominique Thorne), a young prodigy with an engineering mind comparable to Tony’s. First introduced in *Black Panther: Wakanda Forever*, Riri has been studying Stark’s designs, crafting her own armor, and learning what it means to be a hero. When a new threat arises, one tied to Stark Industries’ hidden projects and past decisions, Riri must take on the mantle of Ironheart, balancing her admiration for Tony with her drive to forge her own path.

Alongside her is Pepper Potts (Gwyneth Paltrow), who steps in as a mentor, guiding Riri in understanding the responsibility and risks that come with wearing the suit. They join forces with James Rhodes, a.k.a. War Machine (Don Cheadle), and Happy Hogan (Jon Favreau) to protect Tony’s legacy. The antagonist, rumored to be Ezekiel Stane (son of Tony’s old enemy, Obadiah Stane), leverages stolen Stark technology, determined to avenge his father and exploit Stark’s inventions for world domination.

Directed by Jon Favreau, *Iron Man 4* brings a blend of intense action, cutting-edge visuals, and emotional depth, honoring Tony Stark’s impact on the world and exploring the line between innovation and responsibility. With high-stakes battles, stunning tech advancements, and a fresh take on heroism, *Iron Man 4: New Chapter* is set to reignite the legacy of Iron Man for a new era of fans and heroes alike.
