Obviously this statue in Justice League was just a way to tease Atlantis’ DCEU history, but who knows, maybe Atlan could follow suit like his comic book counterpart and be resurrected for an Aquaman sequel.
You can head over to Reddit to look at this Justice League artwork for yourself, but it depicts Aquaman underwater and gazing at a statue of the “Dead King,” who is seated upon an octopus-designed throne.
After losing the throne and his family, Atlan sunk Atlantis, and in the present day, he was revived to continue his mission of vengeance.
In the New 52 comics continuity, the “Dead King” was Atlan, who ruled Atlantis centuries ago, but was betrayed by his brother Orin, who usurped power.
