Jason Momoa is back as the fictional King of Atlantis to defend his underwater kingdom from the revenge-seeking Black Manta, who vows to “kill Aquaman and destroy everything he holds dear” in the teaser of Aquaman and the Lost Kingdom, dropped by DC on Monday.

The 30-second-long teaser shows Momoa’s Arthur Curry a.k.a Aquaman facing a new threat from Yahya Abdul-Mateen II’s Black Manta, who possesses the power of the mythic Black Trident and is on the path to avenge his father’s death.

As they engage in a fierce battle, Arthur’s family living above the sea surface is also drawn into this conflict when they come under attack by menacing underwater creatures. “I am going to kill Aquaman and destroy everything he holds dear,” Black Manta vows. The teaser doesn’t show Amber Heard’s character Mera.

Directed by James Wan, who directed the 2018 Aquaman, the film also stars Patrick Wilson, Amber Heard, Yahya Abdul-Mateen II and Nicole Kidman. It is produced by Peter Safran, Wan and Rob Cowan while Galen Vaisman and Walter Hamada serve as executive producers.

The logline reads, “Having failed to defeat Aquaman the first time, Black Manta, still driven by the need to avenge his father’s death, will stop at nothing to take Aquaman down once and for all. This time Black Manta is more formidable than ever before, wielding the power of the mythic Black Trident, which unleashes an ancient and malevolent force. To defeat him, Aquaman will turn to his imprisoned brother Orm, the former King of Atlantis, to forge an unlikely alliance. Together, they must set aside their differences in order to protect their kingdom and save Aquaman’s family, and the world, from irreversible destruction.”

Aquaman and the Lost Kingdom will hit the theatres on December 20.
