Ironheart (2025) showcases Dominique Thorne as Riri Williams, a brilliant young inventor stepping into her destiny as the next great armored superhero of the MCU. The trailer opens with a look at Riri’s humble beginnings in Chicago, where she’s seen tinkering with advanced technology in her small workshop. It’s clear from the start that Riri is no ordinary teenager, possessing a genius-level intellect on par with Tony Stark.
The trailer quickly shifts to Riri’s life at MIT, where she’s working on a groundbreaking project to create her own suit of armor, inspired by Iron Man. There’s a brief emotional nod to Tony Stark, as we see Riri watching footage of Iron Man’s heroic sacrifice during Avengers: Endgame, with a voiceover suggesting that she feels a deep connection to his legacy. Determined to honor Stark’s memory and push the boundaries of what she can achieve, Riri builds her first version of the Ironheart suit, though it’s a rough, less-refined version than what fans may expect.
Suddenly, the stakes rise as Riri becomes the target of a mysterious villain who seems to want her technology for their own sinister plans. Rumors suggest the antagonist could be Ezekiel Stane, the son of Obadiah Stane from Iron Man (2008), or perhaps even a new version of the tech-savvy villain The Hood, played by Anthony Ramos, who is glimpsed briefly in the trailer. Explosions, high-speed chases, and intense battles show Riri testing her suit, which evolves throughout the trailer into a more advanced and sleek version, similar to Iron Man’s but with her own unique flair.
The trailer ends with Riri standing tall in her fully realized Ironheart suit, the heart-shaped arc reactor glowing brightly in the center. She says, “I’m just getting started,” before blasting off into the sky, ready to take on her new role as a protector.
