What was Beyoncé’s alter ego called in the two-part album I Am... Sasha Fierce?

Beyoncé’s alter ego in I Am... Sasha Fierce was called Sasha Fierce.

Beyoncé released I Am... Sasha Fierce on November 12, 2008. The double album was designed around two contrasting sides: “I Am...” focused on more personal ballads, while “Sasha Fierce” represented a bolder, more performative persona.

The album included major singles such as “If I Were a Boy,” “Halo,” “Diva,” and “Single Ladies (Put a Ring on It).” “Single Ladies” became especially associated with the Sasha Fierce side because of its energetic performance style and widely imitated choreography.

Beyoncé later said that she had moved beyond the Sasha Fierce persona, explaining that the alter ego had helped her become more confident onstage. “Yoncé” and “Queen Bey” are other nicknames associated with Beyoncé, but neither is the alter ego named in the album title.
