The awesome footage contains Jason Momoa's Aquaman swimming underwater, approaching something on the other side of the screen.
If you look closely, you'll see there's another person standing there. If you look even closer, you'll notice that it really resembles one of Aquaman's biggest foes.
The helmet on the person makes it seem like Aquaman is approaching his evil half-brother, Orm The Oceanmaster.
Orm has already been revealed to be one of the villains for the Aquaman solo film in 2018, along with Black Manta. Veteran actor Patrick Wilson has signed on to play the role.
While it hasn't been confirmed, the character looks exactly like the Oceanmaster, judging by the armor and helmet. The only other reasonable option here is that the figure could be one of Orm's soldiers.
If you're getting excited for Aquaman to hit theaters, be sure to give it an anticipation rating below, and see how it stacks up against the other upcoming superhero films.
