Justice League: Paradox in a New Earth
Unknown Alter Ego
Black Manta was a high-tech pirate who killed Aquaman’s son and the King of Atlantis was looking for him. He was also responsible for Aquaman’s earlier disease, a plague that he wanted to use to kill all atlanteans. He has a pirate ship with the same stats as a Atlantean Frigate.
See the events that are called Atlantis versus Themyscira for more details on the current status.
