Shuri

How is Riri going to fully become Ironheart without Shuri (Letitia Wright), especially given the MIT student genius so recently helped Shuri become Black Panther? They fought together against Namor’s (Tenoch Huerta) army in Black Panther: Wakanda Forever, and Williams even left behind her exoskeleton prototype like an ex-girlfriend leaving a pair of earrings at her partner’s apartment. You know at some point that’s going to lead them back to each other.
Shuri and Riri are currently the two smartest people in the new era of Marvel superheroes (sorry, Peter Parker), and their chemistry on camera provided some of the best aspects of the second Black Panther film. Also, with Black Panther director Ryan Coogler executive producing Ironheart, Shuri dropping by seems like a no-brainer.
