Aquaman is one of the playable in-game characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Extended Universe franchise.
Arthur Curry is the King of Atlantis, as well as a superhero who became known as Aquaman. While initially reserved and content with his isolation from the surface world, Aquaman would eventually be recruited by Batman to join the Justice League in order to help defend Earth against the forces of Steppenwolf and his Parademon army.
Following his recruitment to the team, Arthur played a pivotal role in reviving Superman a year after the latter's death. With the League now assembled, Aquaman helped driving back Steppenwolf, forcing the alien invasion into retreat.
Afterwards, Arthur reluctantly decided to finally pursue his rightful place in Atlantis – he retrieved the Trident of Atlan from the Hidden Sea, defeated Orm, and became king, though he had also unintentionally created a new and dangerous villain, Black Manta.
