Both series take their inspiration from the 1990 Luc Besson film Nikita, with La Femme Nikita airing on the USA network from 1997 to 2001.
"[My show] is the future of Nikita," Q told Movieline. "This is a Nikita we've never seen. This is the first time she's ever had control of her destiny."
She continued: "That's a cooler place to be, I think. We've moving forward with her. I kind of don't give a s**t about what anyone thinks of La Femme Nikita. It's done!"
The actress also claimed that the CW version of Nikita is more "mainstream" than the USA series.
"I've been approached by kids, cops, white, black, Latino, 70 [and] 17 [year olds]," she explained. "It's not a cult thing. The CW, as a smaller network, [doesn't] get as much exposure as larger networks, but I think we're doing pretty good on that note."
Nikita continues on Thursday at 9/8c on The CW.
