While little is known for sure, the expectation is that the end of the Marvel Cinematic Universe’s Phase 3 will also be the end of Robert Downey Jr.’s run as Iron Man.
The MCU would certainly be lacking if it lost its super intelligent, super creative, tech genius with a super fast wit.
The title character’s sister, Shuri, played by Letitia Wright, could fit nicely into the gap that Robert Downey Jr. would leave behind.
She’s the perfect character to take over as a new Iron Man, or if that’s not the plan for her, she could help locate the person who could.
