Scarlett Johansson's time as Black Widow in the MCU has come to an end with her last appearance in the solo film "Black Widow." Unlike the grand send-offs of Iron Man and Captain America, Johansson's exit was more understated but still impactful. Her role in the MCU expanded due to audience reception, and she credits being one of the original cast members for her evolving contract. Although her official contract end date is unknown, "Black Widow" is widely accepted as her exit. The release of the film was marred by controversy, as Johansson sued Disney for breach of contract regarding its simultaneous release in theaters and on Disney+.
The lawsuit has since been settled, but Johansson still seems set on taking a break from the character. While it's not impossible for her to return in some capacity, it doesn't seem likely as of now.
