If you are wondering how long until we get to meet the newest member of the team, Zari Adrianna Tomaz (Tala Ashe), I can tell you that she will be popping up in the third episode DC's Legends of Tomorrow season three, deceptively titled, Zari. They synopsis says that the team tries to protect an outlaw named Zari to try and capture a rogue time traveler. This will lead to here becoming part of the team, though not all of the Legends are on board with the idea… including Zari herself.
Ashe talked with EW.com about the character becoming part of the Legends.
"She's not an obvious choice to join the Legends, and to be part of a team. In the early episodes, you're going to see that she's fighting the narrative of being a superhero, but also being part of a team and trusting people because I think that's something that has burned her in the past. Because of her upbringing, it's not something that she easily adheres to. She is brilliant in that sense and says what's on her mind, and it's a different tone to bring to the group of Legends. She shakes them up and challenges their mission."
We're told that she pushes the Legends to do more than just fix time, but to try and make it better. Coming from the future, she knows more about what happens. Definitely a different dynamic than the one where they're just supposed to put things right.
DC's Legends of Tomorrow airs Tuesdays at 9 p.m. ET on the CW.
