Black Manta is a supervillain in the DC comics and the secondary archenemy of Aquaman. Black Manta is one of many mysteries of the sea. Manta currently claims that he was an autistic boy who grew up in Arkham Asylum, where he was subject to many unethical experiments. One such experiment increased his knowledge, but made him a sociopathic madman in the process. Escaping from Arkham, Manta decided to take over the seas, seeing it as a safehaven from the cruelty of the surface world. But Manta has proven to be just as heartless as the scientists who tormented him as a boy, and has frequently fought Aquaman. But now their war has become personal, since Manta caused the death of Aquaman's son, Arthur Curry Jr., an act that truly proves that not all sea monsters are animals. In the current Brightest Day miniseries, it has been revealed that Black Manta is the father of the new Aqualad, Jackson Hyde, and his true origin may come to light.
