While Aquaman hasn't been officially confirmed, many believe that Jason Momoa will be playing the role with a possible appearance in the next DC movie before showing up full-time in the Justice League movie that is planned for 2017. But will Aquaman be dealing with when he joins the team?
One of the recent story lines for the aquatic hero is The Throne of Atlantis story that was a comic book narrative from 2012-2013 and is being made into an animated feature.
In the comics, when a Navy warship incites the wrath of the Atlanteans after its missiles malfunction during a test and end up attacking Atlantis. Ocean Master, the new king of Atlantis, declares war on the surface world. While they are in a café in Metropolis, Superman and Wonder Woman are forced to suit up and stop an aircraft carrier from flooding into the city and killing thousands of people.
In the battle that follows the Justice League is captured, save Cyborg. He realizes they need help and calls in help from Green Arrow, Hawkman, Zatanna, Firestorm and more. The Heroes stop Ocean Master and figure out that Aquaman's assistant Vulko was behind the bombing so Arthur would take the throne once again.
While Justice League may not follow this, the storyline could be something that they look to do in the future with the beginnings happening in the solo Aquaman movie that is being planned.
Justice League is set to follow Batman v. Superman in 2017.
