Who Riri Williams is and where she first shows up
Riri is a teenage engineering prodigy studying at MIT who builds things most adults could not. Her first scenes come in Black Panther: Wakanda Forever, and the way she enters the story is a neat piece of plotting. For a class project she designs a machine that can detect vibranium, the rare metal Wakanda has spent generations hiding. That invention makes her a target, and Shuri and Okoye travel to Massachusetts to reach her before someone more dangerous does.
What makes her stand out right away is attitude. Riri is cocky, funny and a little reckless, the kind of student who builds a flying suit in a dorm workshop because nobody told her she could not. The comparison to a young Tony Stark is deliberate, and the films lean into it without turning her into a copy.
Her titles in order
- What If...? (series, optional): an alternate-universe animated appearance
- Black Panther: Wakanda Forever (film, recommended)
- Ironheart (series, optional)
- Marvel Zombies (series, optional): animated, set in a separate universe
The two animated titles sit outside the main story. The film gives her the origin and the first armor, while the series is where she finally gets room to grow.
Turning points, kept spoiler-light
In Wakanda Forever, Riri is more of a catalyst than a lead. She is the reason two hidden nations end up in conflict, and she spends much of the film learning that brilliance has consequences. By the end she has earned the trust of people who rarely trust outsiders, and she leaves with a clearer idea of who she wants to be.
The series moves her back home to Chicago. There, her high-tech approach to armor runs into something she cannot engineer around: magic. She gets pulled into the orbit of Parker Robbins, a charming crew leader known as The Hood, and the show becomes a test of how far she is willing to bend her own rules to keep building. It is a grounded, street-level story compared with the global stakes of the film.
Characters around her
Riri does not have a long list of recurring MCU partners yet. In the movie she is tied mostly to Shuri, who sees a version of herself in the young inventor, and to Okoye. In Chicago her circle is personal: her mother Ronnie, old friends from the neighborhood and N.A.T.A.L.I.E., an AI that matters to her in ways the show handles with care.

Dominique Thorne in the role
Dominique Thorne plays Riri in both titles, which gives the character a steady voice from her first scene to her first solo outing. Thorne brings quick comic timing and a stubborn edge, so Riri reads as gifted and young rather than polished. Before Marvel she was known for supporting parts in prestige dramas, including If Beale Street Could Talk and Judas and the Black Messiah. Ironheart is her first time carrying a series as the lead.
Best order to watch her story
Start with Wakanda Forever. It is the stronger and more important title, and without it the series opens on a character you do not know. Then move to the Ironheart series when you want more of her. We rate the show optional because later MCU films do not depend on it so far, but if you liked Riri in the movie, it is the obvious next step and gives her a full arc of her own.
