Supergirl is the next DC hero to head from the pages of a comic book to the TV. CBS has placed a series order for Supergirl, which is being created in part by one of the producers behind CWs Arrow and The Flash. The show will focus on Kara Zor-El, the cousin of Superman, as shes finally beginning to use her powers at age 24 (which technically makes her more of a Superwoman, but we digress).
