Sonequa Martin-Green Played Sasha in ‘The Walking Dead’

Sonequa is perhaps most famously known for her portrayal of Sasha Williams on The Walking Dead from 2012 to 2018. A former firefighter and a survivor of the outbreak, Sasha was first introduced in season 3, alongside her character’s brother, Tyreese Williams (Chad L. Coleman).

Her time on the popular zombie drama came to a tragic end in season 7 when Sasha took her own life in a final sacrifice so that she could turn herself into a Walker and attack Negan (Jeffrey Dean Morgan).

“It just felt so right,” Sonequa said of Sasha’s demise on The Talking Dead. “It felt so complete. It was quite poetic when I found out how it was going to happen. Because I felt like it was the perfect end to my story, the perfect culmination of my life. I felt like all of my roads had led to that moment of getting to that place of complete selflessness. It felt perfect.”

“In front of the camera, I’m particularly proud of making television history. In front of the camera, I’m proud of how bold we were as an iteration,” she told Trekmovie.com in April 2024. “That we did things that no other Trek has done. We were serialized to a degree that no other Trek has been. We went to a future beyond where any Trek has gone. We made television history with diversity in a way like never before. So, I hope that boldness is part of our legacy. “
