On November 7, 2016, Warner Bros. Animation announced that the show would return to production due to huge demand after a three-year absence. The third season debuted on DC's streaming service in January 4, 2019.
Aqualad's tattoos are only visible because he never finished his training in the sorcery of magic. The tattoos would have become invisible if he had finished it, just like the other Atlantian magic users Garth and Tula, whose tattoos are hidden and become visible when they use their magic.
Aqualad/Kaldur'ahm was created for this series. Geoff Johns and Ivan Reis liked the character so much that they adapted him for the DC comic books (with dreadlocked hair and the alter ego Jackson Hyde) debuting in Brightest Day #4. Johns revealed that the new Aqualad was added to the comics because Khary Payton asked for the character to be included in the comics.
The producers went into this series with two goals: to capture the interests of not only the youngest kids, but also the older crowds and to make the show feel as realistic as they could with animation.
