What Happened To Everyone Who Joined The Birds Of Prey?
4. Hawkgirl
Oh boy, this character. Nothing wrong with the character of Hawkgirl herself, it's just that mapping out the character's history and background is like trying to make sense of the Doctor Who continuity: long, fruitless, and will just leave you lying, defeated and VERY drunk in a corner while the picture of Matt Smith grins mockingly at you from the opposite wall.
To break it down as simply as I can, the Hawk line is a reincarnation cycle, whose latest incarnation is Kendra Saunders. After she committed suicide, she was reborn with the powers of the golden age Hawkgirl, Shiera Hall.
Hawkgirl mostly stuck with Hawkman and the Justice League, but joined the Birds of Prey when Oracle recruited her to take on the Secret Six.
Hawkgirl stuck around after that, but of course along came the New - 52 to ruin everything. Yeah, as you have no doubt surmised from this list, the reboot was especially cruel to team books like this and ESPECIALLY the Teen Titans.
Fortunately, Hawkgirl is still around unlike contemporaries such as Lady Black Hawk, so there's still a chance that the Birds of Prey will acquire Hawkgirl's services again.
