In the second draft that was filmed, Justice League: The First Mission was an animation put together by the Justice League production team while shopping the series to Kids' WB!. Since it was for the Kids' WB! Bruce Timm and crew added in three teens to make WB happy. These teens were Robin (Tim Drake), Impulse (who would have replaced The Flash) and Cyborgirl (a new character) to fight along side Batman, Superman, Wonder Woman, Green Lantern (John Stewart), Martian Manhunter, and Hawkgirl.
