Kaldur'ahm (Earth-5430)

Kaldur'ahm is the son of Black Manta, but after being rescued by Aquaman following a failed attempt of Black Manta to seize control of Atlantis, Kaldur'ahm was raised as Aquaman's son. As he grew, Kal became a hero, much like his adoptive father, going by the alias of Aqualad, as a founding member of the Teen Titans, and then a member of the Justice League Unlimited.
