Murk

Murk is the captain of Ocean Master's royal guard and a supporting antagonist in the 2018 superhero movie Aquaman.

History
After Arthur escaped from Atlantis with Mera to go look for the trident of the first king of Atlantis, Orm sent Murk and his royal guards to go hunt down and kill Arthur as well as retrieve Mera for her father. Along the way, the guards delivered some high-tech Atlantean weaponry to Black Manta and recruited him to help them hunt down Aquaman.

Murk and the guards manage to track Arthur and Mera to Sicily thanks to the ring Orm had placed on Mera's finger prior to their escape. The guards ambush the two, with Black Manta fighting Aquaman while Murk attempts to incapacitate Mera. Despite having his hand cut off by Mera, his armor quickly heals the wound and allows him to keep on fighting. Mera later breaks his helmet as well, forcing Murk to rush over to a toilet and dips his head since, as a non-highbreed, Murk is unable to survive without water. He is not seen afterward.
