Atlantis (Aquaman)

Atlantis (sometimes called the Kingdom of Atlantis or the Atlantean Empire) is the fictional aquatic-based civilization appearing in American comic books published by DC Comics commonly associated with the superhero, Aquaman. Its depiction is most recognizable one within DC Comics, first appearing in Adventure Comics #260 (May 1959), and was created by Robert Bernstein and Ramona Fradon. Typically either a reoccurring or main setting of most Aquaman stories, the nation is characterized as being inhabited by human-like beings and creatures with biological, aquatic adaptations as well as typically following a hereditary monarchy. Atlantis is portrayed within DC Universe as being among the oldest and most powerful of civilizations on Earth due to its advanced technology and connection to the arcane forces on Earth. Beginning as a utopia, the nation would collapse to the bottom of the ocean after a cataclysmic event. Over time, the nation's history would be embordered in conflict with regards to its succession of rulers, the nation's status as a superpower, its fictional cultural heritage, and the relationship with the global world in the modern age.

The Kingdom of Atlantis made its cinematic debut in the 2017 film Justice League, set in the DC Extended Universe, and was later more prominently featured in the 2018 film Aquaman and the 2023 film Aquaman and the Lost Kingdom.
