The new "Aquaman" trailer is a five-minute video revealing Arthur and Mera's search for King Atlan's trident [VIDEO] as they travel to the Sahara desert to look for more clues inside his tomb. Screen Rant reported that Atlantis was once on the surface during Atlan's rule and he united the seven cities. Arthur and Mera learned that the Trident has the ability to command the whole ocean life or destroy it if it falls into the wrong hands.

The trailer also revealed that two heroes are being hunted by Black Manta and Orm's elite guard as they chase them around the city. Orm provided Manta's armor and weaponry in exchange for getting rid of his brother and retrieving the Trident.

Mera's father, King Nereus, appeared in the trailer and he defends his home Xebel, from Orm's army.

The location of the Trident is hidden in the deepest darkest depths of the ocean, but it guarded by dangerous fish-like humanoids called the Trench.

There is also an extended look at Arthur's parents, Thomas and Queen Atlanna, and his classic orange and green armor from the DC Comics. Mera believes that Arthur is the key to unite Atlantis and a bridge for peace between two worlds.
