First debuting in Marvel's comics in 2016's Invincible Iron Man, Riri was mentored by Tony Stark and even created new armor and, with it, a new title: Ironheart. The live-action adaptation of the character in Wakanda Forever kept her MIT origins and saw Riri create a vibranium detector and, later, join forces with Shuri.

The trailer kicks off with Riri Williams (Dominique Thorne) being tasked with using her genius to escape from a classic death trap in an elevator. The death trap's creator is Parker Robbins, aka The Hood (Anthony Ramos), who is looking to recruit Williams and wants to test her.
