Iron Man 4 (2025) is one of the most anticipated entries in the Marvel Cinematic Universe, bringing new life to the legacy of Tony Stark and the Iron Man mantle. While Robert Downey Jr.’s iconic portrayal of Tony Stark remains untouchable, this sequel explores the future of Stark’s technology and the ripple effects of his genius on the world he left behind.

Set several years after the events of Avengers: Endgame, the film introduces a new protagonist who takes up the Iron Man mantle. The story focuses on Riri Williams (Dominique Thorne), the young inventor introduced in Black Panther: Wakanda Forever and star of the Ironheart series. Riri’s journey as a genius inventor thrusts her into the spotlight, where she must navigate the challenges of carrying on Tony Stark’s legacy while forging her own path. Riri faces a powerful new villain equipped with Stark’s stolen technology, forcing her to confront the dangers of unchecked innovation. Along the way, she receives guidance from familiar faces, such as Pepper Potts (Gwyneth Paltrow) and Happy Hogan (Jon Favreau), and uncovers secrets from Stark’s past that could change her future.
