Aqualad/Kaldur'ahm was created for this series. Geoff Johns and Ivan Reis liked the character so much that they adapted him into the DC comics, appearing in Brightest Day #4 (with messy hair and the alter ego Jackson Hyde). Johns explained that the new Aqualad was added to the comics because Khary Payton wanted the character to be included.

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.

In January 2016, producer Greg Weisman announced that the series had been cancelled because Mattel had discontinued its toy line. The series' funding depended on a toy deal with Mattel, and since there was no revenue source large enough to replace Mattel's money, a third season was not picked up for several years.

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. The series also featured new characters who were outside the superhero life and were not even sure they wanted to be superheroes. This contrasts with the original team in Season 1, who were familiar with the superhero life and had inside knowledge because they were the Justice League's protégés.

The man who raised Aqualad/Kaldur'ahm was Black Manta's servant Calvin Durham, who was biologically altered by Black Manta so he could live underwater. He was supposed to infiltrate Atlantis, but instead fell in love with Aqualad/Kaldur'ahm's mother and left Black Manta's organization. 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.

Lagoon Boy joins the team in the second season. He is an Atlantean named La'gaan and was first shown as a student at the Conservatory of Sorcery in Lori Lemaris's first season. In regular conversation, usually when caught off guard, Lagoon Boy tends to use Atlantean slang or euphemisms such as "Neptune's Beard!" He is also dating Miss Martian, whom he calls "Angelfish."

This series explicitly states that Black Lightning's ex-wife Lynn Stewart is the sister of Green Lantern John Stewart. Black Lightning comic fans had speculated this for years, and co-creator Tony Isabella confirmed he intended to connect the characters but never got the chance to do so. However, at the time of Season 3's production, it had still not been confirmed or made canon in the main DC comics.

When the memorial statues are shown after Artemis's death, an unnamed Robin is among the dead. This is most likely the second Robin, Jason Todd (the first being Dick Grayson/Nightwing and the third Tim Drake). In the comics, Jason eventually returned as the villain/anti-hero Red Hood and ultimately created his own superhero team called the Outlaws. There are two versions of this group, one featuring Arsenal and the other Bizarro Superman, and both characters appeared in the series.

In January 2013, Cartoon Network announced that the series would be cancelled after the remaining episodes of the second season aired in the DC Nation Saturday morning block. Cartoon Network replaced the series with reruns of Teen Titans Go! (2013) (with new episodes airing on Thursdays), but the block still used artwork from this series in its commercial bumpers.

Most members of the team can shift their costumes to a darker color scheme using stealth technology, which helps them blend into their surroundings on covert missions. Robin and Superboy are the only ones whose costumes do not have a stealth mode. However, Mattel released a Robin figure in its toy line wearing the blue Stealth Tech costume instead of his usual red look.
