    Quite early in the development process, it was decided that this would be a young DC universe in which the heroes had not been around for that long. Once that decision was made, producer Greg Weisman chose to use Dick Grayson and Wally West as Robin and Kid Flash, because rather than being a strict adaptation of the Young Justice comic featuring Tim Drake and Bart Allen, he felt they were working with a whole history and legacy that was truly critical to the story.

    Lead character designer Phil Bourassa and producer Brandon Vietti made a conscious decision to try to approach the Justice League with a slightly more classic design sensibility than the Young Justice team. They did this to try to visually show the difference between the generations, since the series is entirely about that dynamic.

    Season 3 premiered in 2019 under the title "Young Justice: Outsiders" and dealt with illegal meta-human trafficking taking place worldwide and across the galaxy.

Aqualad always believed Calvin Durham was his father until he discovered that Black Manta was in fact his biological father, which led to the events of the second season.

There are two versions of this group, one featuring Arsenal and the other Bizarro Superman, and both characters appeared in the series.
