Surfacing on Reddit, the image depicts what appears to be armed Atlantean soldiers pursuing Mera (played in the film by Amber Heard), who leaps from one rooftop to the next.

That scenario suggests Aquaman could delve into Mera's updated comic book origin, in which she's a princess of Xebel, a mostly forgotten extradimensional penal colony for an ancient group of separatists banished by Atlantis behind a sealed portal. That positions Mera initially as an enemy of Aquaman and his undersea kingdom. That revised origin was written by Geoff Johns, DC Entertainment's president and chief creative officer, who collaborated with Wan on the film's story.
