Before Black Manta became Aquaman's greatest enemy, his father was killed by Aquaman, sparking the vendetta that Manta held for the Atlantean and beginning his career as a criminal.
During the fifth year of Superman's regime, Harley attempted to call her former Suicide Squad members, one of those calls going to Black Manta, however his mask rested at the bottom of the ocean, implying he had perished.

"Brainiac stole Atlantis. For that, I could have thanked him. But that wasn't enough. Arthur Curry's kingdom had to be wiped from history. Forgotten. Lost. As it should be. I found just the place, guarded by Earth's most savage predators. Once upon a time, Arthur Curry killed my father. Now that I've killed his kingdom, all that remains is to kill "the king" himself. Only then will I consider my father's murder avenged. Only then will I rest."
"And what of Aquaman? Does he come forward to avenge his own people? No. He hides behind an alien and an amazon. Let him. It won't save him. Compared to that alien freak Brainiac, these three will be fish for the slaughter. And when they're dead, the world can thank Black Manta."
