Before we see what Jason Momoa will bring to the role for DC/WB, Aquaman is all set to make his debut in DC Entertainment and Warner Bros. Animation’s new movie-verse with Justice League: Throne of Atlantis.

Fans have already been given a look at a short teaser for the film along with an entire clip, but the newest trailer provides a bit more insight into how Arthur Curry (voiced by Matt Lanter) becomes both the hero the world knows as Aquaman, and ruler of the undersea kingdom, Atlantis.

Throne of Atlantis will continue the story first established with Justice League: War, the launching point for the animated adaptation of DC Comics’ New 52 continuity. War saw the formation of the Justice League as Superman, Batman, Wonder Woman, Green Lantern, The Flash, Shazam, and Cyborg came together to thwart an invasion by Darkseid, but Aquaman – who is present in the comic book origin of the New 52′s League – was noticeably absent.

We now know that implied slight was anything but, with the studio holding off on bringing Aquaman into the mix, waiting instead for the second arc from the New 52 Justice League series (featuring Aquaman’s half-brother, Orm, leading an army of Atlanteans in an attack against the surface) to act as a backdrop for Aquaman’s origin. Otherwise, his origin appears to remain mostly unchanged. Still the son of a human lighthouse keeper and an Atlantean queen, it’ll be up to Arthur to unify both worlds.

What this trailer doesn’t clear up, however, is exactly what role Mera (voiced by Sumalee Montano) will play in the proceedings. The trailer gives the impression that she arrives from Atlantis seeking Arthur at the request of his mother, but recent comics have revealed that Mera is actually from an Atlantean penal colony, Xebel. In the comics, she was sent to assassinate Arthur, instead falling in love and later becoming his queen (while still remaining a formidable warrior).

We’ll have to wait and see exactly what changes have been made to both Arthur and Mera’s origins in Throne of Atlantis, but there’s a possibility that the story established here could be a precursor to whatever awaits them in the DC cinematic universe. Then again, there’s really no telling how similar or not DC/WB are intending Momoa’s Aquaman to be with his comic book counterpart.

Throne of Atlantis also stars Jason O’Mara as Batman, Jerry O’Connell as Superman, Nathan Fillion as Green Lantern, Christopher Gorham as The Flash, Sean Astin as Shazam, Rosario Dawson as Wonder Woman, Sean Patrick Thomas as Cyborg, and Sam Witwer as Orm.

It’s directed by Ethan Spaulding (Avatar: The Last Airbender) from a script by Heath Corson (Batman: Assault on Arkham), with James Tucker (Batman: Brave and the Bold) producing.

Justice League: Throne of Atlantis will release on Blu-ray/DVD on January 27th, 2015.
