Black Manta engages in undersea crime in an attempt to conquer the world beneath the waves. However, Aquaman thwarts Black Manta at every turn, a conflict that has led to Black Manta's murder of Aquaman's infant son. Tiring of his constant defeats, Black Manta sold his soul to the demon Neron for greater power and was thus transformed into a true denizen of the deep.

Includes the left leg of Gorilla Grodd.
