When Vixen appears on "DC's Legends of Tomorrow," she won't be Mari McCabe, the modern day version of the character who appeared on "Arrow" last year. Instead, she'll be Amaya Jiwe (Maisie Richardson-Seller), Mari's grandmother from the 1940s and a member of the Justice Society of America -- and executive producer Marc Guggenheim revealed that those facts will factor into her interaction with the other Legends.

"You've got Captain Cold, who was a criminal and out for himself. He's replaced by Vixen, who is the definition of a superhero," he explained. "She's a member of the Justice Society of America, she's from the 1940s, everything is prim and proper -- not stuck up, but she does things right. You have this team that doesn't do things right, they're a bunch of fuck-ups. So she's interesting counterpoint."

Jiwe won't be the only JSA member making her way onto the show. At Comic-Con International in San Diego, fans also learned some of the other heroes that will fill the team's ranks: Obsidian, Stargirl, Doctor Mid-Nite and Steel.

Created by Gerry Conway and Bob Oksner for 1981's "Action Comics" #521, Vixen receives her powers through an ancient totem that's passed through generations of the mantle-bearer's family.

Starring Brandon Routh, Caity Lotz, Arthur Darville and more, "Legends of Tomorrow" returns to The CW for its second season on Thursday, Oct. 13, at 8 p.m. ET/PT.
