According to Bruce, the original pilot of Justice League featured some younger members of the team which were to be included because kids it would be a kids show. Several of the actual characters that became members on the show were also included in the pilot. The younger characters were Impulse, Robin and a robotic female character created for the show. Bruce managed to get the show approved over the phone so the pilot never had to be shown to the network. It is now included in the Justice League Season 1 DVD.
