Kaldur'ahm
The calm center of a storm of heroes, holding the Team together when every mission demands impossible choices.
Kaldur'ahm, also known as Jackson Hyde, is a superhero appearing in both media published by DC Entertainment and American comic books published by DC Comics. While the character was created by Brandon Vietti, Greg Weisman and Phil Bourassa for the television series *Young Justice*, and voiced by Khary Payton, the comic book version debuted earlier in *Brightest Day* #4 (July 2010). Though intended as incarnations of the same character with similarities—such as sharing the codenames Aqualad and Aquaman, and being the biological son of Black Manta—their histories and backgrounds diverge significantly. The animated version's name is derived from Cal Durham, a henchman and right-hand assistant of Black Manta in the comics. Within the television series, Kaldur'ahm is the son of villain Black Manta and Atlantean Sha'lain'a, raised by the latter alongside his adoptive father Cal Durham, who settled in Atlantis after abandoning an infiltration mission and genetically altering himself with Atlantean traits. Known for his mature and responsible demeanor from a young age, he became Aquaman's protégé after Aquaman and Garth rescued him during a battle with Ocean Master. Over time, as a member of the Team, he rises as a skilled and measured leader before eventually adopting the Aquaman codename in season three.

Lore & Background
Kaldur'ahm is the protégé of Aquaman and a founding member of the Team. Between the first and second seasons, he learns that Black Manta is his biological father—a revelation that reshapes his identity. The episode "Downtime" reveals that Aquaman recruited Kaldur after he and Garth rescued him during a battle with Ocean Master. Garth was also offered the role of Aquaman's sidekick but chose to remain in Atlantis to continue his sorcery studies. In season two, *Invasion*, Kaldur goes undercover within the Light to uncover their secret partner. During a tense confrontation at a summit between the Light and the Reach, he reveals himself and exposes the Light's betrayal. In season three, *Young Justice: Outsiders*, Kaldur becomes the new Aquaman after Orin retires. The series also reveals that Kaldur is in a relationship with an Atlantean man named Wyynde, adding depth to his personal life.
In Their Own Story
Kaldur'ahm's Atlantean hybrid physiology grants him superhuman strength, durability, enhanced senses, the ability to breathe underwater, and the capacity to swim at incredible speeds, along with a noted resistance to poisons. Beyond his natural gifts, he trained in the mystic arts at the Conservatory of Sorcery, earning distinctive eel-shaped tattoos that channel his magical abilities. With these, he can generate electricity, bend and shape water at will, create hard-water constructs, and cast spells. In addition to his powers, Kaldur is an expert combatant and a brilliant tactician, having led both the Team and later the Justice League as chairman. He is also a skilled deceiver, having successfully maintained a deep-cover infiltration of the Light for months, balancing loyalty, sacrifice, and manipulation without breaking.
