The CW's spinoff of The Flash and Arrow mostly remains a mystery. The odd assortment of characters is the biggest question mark. It's described as a team-up series but it sounds more like a Brave and the Bold-style anthology with such a mixed lineup. Most recently a character breakdown was unveiled that listed three characters still to be cast, and now we know one of them will be Kendra Saunders aka Hawkgirl.

In the spinoff series, Kendra will have learned she's been reincarnated numerous times over the course of centuries, with her warrior personality coming out, along with a set of wings, when provoked into action.
Renée joins Brandon Routh as the Atom, Wentworth Miller as Captain Cold, Dominic Purcell as Heat Wave, Victor Garber as Dr. Martin Stein, and Caity Lotz in an unspecified role. There are still three characters, which have never been seen on TV before, that need to be cast. Hawkgirl doesn't count as she was seen on an episode of Smallville and has been part of the various Justice League animated shows. [Deadline]
