Black Panther: Wakanda Forever introduced new characters to the Marvel Cinematic Universe, most notably Riri Williams (Dominique Thorne), best known as Ironheart. Riri is the official replacement of Iron Man in the MCU, and her age is giving her a major advantage over the hero that inspired her to become one. Although it took the MCU some time to recover from Tony Stark’s (Robert Downey Jr) death in Avengers: Endgame, it’s finally moving on and focusing on other, younger characters that will surely take this connected universe’s lead in the near universe, and among them is Riri Williams.
