According to a shocking report from The Wrap, Black Manta will be the primary antagonist in Warner Bros' upcoming Aquaman film. Black Manta has had various origins in the comics over the years, so it's unclear which Manta will appear onscreen, but if past DC cinematic offerings are any indication, we can be certain that it will be a very grim and gritty Black Manta indeed. A human, Black Manta wears a suit that makes him a formidable foe in water. Aquaman, on the other hand, can talk to fish. This epic battle between water-man and fish-guy will play out in theaters in July 2018.
