Every Black Widow In The MCU & Where They Are Now

[هَـ-ђāŵĩ-ـَاوِي]

In recent years, many new Black Widow assassins have been introduced to the MCU, and even more are on the way in upcoming projects. Back in the MCU's Phase 1, Scarlett Johansson debuted as Natasha Romanoff, a SHIELD agent who operated under the codename, Black Widow. For a while, it was thought that she was the only Black Widow in the MCU, but it soon became clear that she was one of many, though it took Marvel Studios a long time to actually introduce any of Romanoff's Black Widow sisters.
