What is "aqualad"

Aqualad is the name of two fictional comic book superheroes appearing in books published by DC Comics. The first Aqualad, Garth, debuted in Adventure Comics #269 (February 1960), and was created by writer Robert Bernstein and artist Ramona Fradon. The second Aqualad, Jackson Hyde, was based on the version originally created for the Young Justice animated TV series by Greg Weisman, Brandon Vietti and Phil Bourassa. Several months prior to the launch of the cartoon, an altered version of the character was brought into the comic books by writer Geoff Johns and artist Ivan Reis.

Kaldur'ahm is one of two fictional superheroes codenamed Aqualad in stories published by DC Comics. The character was created by Greg Weisman, Brandon Vietti and Phil Bourassa for the television series Young Justice, and voiced by Khary Payton. His name is a reference to the character Calvin "Cal" Durham, formerly a henchman of the super-villain Black Manta who was sent to infiltrate Atlantis, but defected to the Atlanteans and subsequently settled down with Aqualad's mother, Sha'lain'a of Shayeris.

Kaldur'ahm was subsequently adapted for the DC mainstream continuity by Geoff Johns and Ivan Reis, debuting under the name Jackson Hyde in Brightest Day #4 (August 2010).
