Black Manta AKA David Hyde

Doctor Stephen Shin to procure a sample of Arthur Curry's blood to prove that the young man was an Atlantean. During the encounter, Arthur's father, Thomas, came to his son's defense and suffered a heart attack. Thomas died three days later, and Arthur swore revenge. On the day of Thomas' funeral, Arthur stormed the boat belonging to the man he deemed responsible for his father's death. In the rain and darkness, Arthur murdered Hyde's father, on the assumption that he was the killer. Out of vengeance, Hyde crafted weapons and armor, and went hunting. When the Atlantean became a publicly-known hero as Aquaman, David became Black Manta.
