Atlantiss

Atlantiss is a fictional underwater city featured in the DC Comics universe. It was created by writer-artist Roy Thomas and artist John Buscema, first appearing in the comic book "Atlantis: The Lost Continent" #1 in 1976. The city is located in the Atlantic Ocean, specifically off the coast of the fictional island of Lemuria. Atlantiss is known for its advanced technology and its inhabitants' ability to breathe underwater, which is achieved through a process called "Atlantis Breathing."

The city is ruled by King Orin, who is aided by his daughter, Princess Atlanna. Atlantiss is a technologically advanced society, with a focus on science and engineering. The city is powered by a device called the "Power of Atlantis," which allows it to remain underwater and function without the need for air or sunlight.

Atlantiss has a rich history, with its origins dating back to ancient times. The city was founded by the Atlanteans, a race of humanoids who were able to breathe underwater. Over the centuries, Atlantiss has been a source of inspiration for many other underwater-themed stories in popular culture, including films, television shows, and video games. Despite its advanced technology and rich history, Atlantiss remains a mysterious and enigmatic place, with much of its past and present still unknown.
