With the numerous adaptations of the DCU in various tv shows, movies and other media, we've had characters debut in these adaptations instead of in the comics. Some have been brought into the comics, others have not but hopefully will be. Of these characters that debuted in adaptations of the DCU, which was your favorite?
Mine are (in no order of appearance):
Livewire (Superman: The Animated Series)
Red X (Teen Titans 2006 Animated Series)
Terry McGinnis (Batman Beyond)
Will Harper (Young Justice)
Chloe Sullivan (Smallville)
John Diggle and Sara Lance (Arrow)
