In the comics, Black Manta first appeared in 1967 in Aquaman #35 as a treasure hunter who was hired to collect a sample of Aquaman’s blood.
Aquaman, the upcoming DC Extended Universe film directed by horror master James Wan has supposedly already revealed the merman’s (Jason Mamoa) big bad as Black Manta.
As he sailed off on his oceanic mission to collect the blood sample, Manta encountered a young Aquaman alongside his father.
Either way, Aquaman versus Black Manta would make for a great on-screen fight.
