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..
