Aquanaut Diver who remains at depth underwater for longer than 24 hours

An aquanaut is any person who remains underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as saturation. Usually this is done in an underwater habitat on the seafloor for a period equal to or greater than 24 continuous hours without returning to the surface. The term is often restricted to scientists and academics, though there were a group of military aquanauts during the SEALAB program. Commercial divers in similar circumstances are referred to as saturation divers. An aquanaut is distinct from a submariner, in that a submariner is confined to a moving underwater vehicle such as a submarine that holds the water pressure out. Aquanaut derives from the Latin word aqua ("water") plus the Greek nautes ("sailor"), by analogy to the similar construction "astronaut".

The sets feature vehicles, characters and scenes from the comics and films. The inspirations for the design of these varies widely. For example, the Batmobile retains its basic sleek shape and prominent fins from the Tim Burton films, whereas the "Bat-Tank" seems to be based on the tank-like Batmobile in Frank Miller's The Dark Knight Returns. In 2008, a video game based on the theme, Lego Batman: The Videogame, was released, along with four new sets. The theme was relaunched in early 2012 as part of the Lego DC Universe Superheroes line, which is a sub-theme of the Lego Super Heroes line.
