Warner Bros. has released a new expanded trailer for Aquaman, starring Jason Momoa as the would-be king of the underwater world of Atlantis and one-time laughingstock of DC’s Super Friends. This time out, the merman has lost his goldie locks and sensitive Pisces nature and gone rock lobster.

Helmed by Saw and Conjuring director James Wan, Aquaman finds our musclebound reluctant hero fighting enemies on land and sea while falling for the sexy Atlantean (Amber Heard) urging him to take his throne as king of Atlantis. In theaters Dec. 21.
