Kaldur'ahm, or Kaldur for short, is the superhero codenamed Aqualad and Aquaman in media published by DC Entertainment. The character was created by Brandon Vietti, Greg Weisman and Phil Bourassa for the television series Young Justice, and voiced by Khary Payton. His name is a reference to the character Cal Durham, formerly a henchman of the supervillain Black Manta who was sent to infiltrate Atlantis, but defected to the Atlanteans. While originally developed for television, DC quickly adapted the character to its mainstream comic books, with Geoff Johns and Ivan Reis' re-interpreting the character. For television, creators were able to tell a story where Aqualad had known and worked with Aquaman for many years, while the comic book version had to be introduced to Aquaman and readers at the same time, meaning aspects of his backstory had to be changed.
