In the late 1940s, writer Mort
Weisinger and artist Paul Norris, created Aquaman. Some say the "Sovereign
of the Seas was merely DC's answer to the popular Timely Comics (later Marvel
Comics) character Namor: the Submariner. But the A-man had a style, and following,
all his own.. According to Wikipedia:
Aquaman's adventures took place all across the world, and the only base he appeared to have was "an ancient temple of lost Atlantis, kept underwater," in which he kept a solitary throne.There was also a structure called the "Aquacave", a dry series of caves in which he kept the "Atlantis Chronicles", although it is unclear if this is distinct from the ancient temple, or the same location.
During his wartime adventures, most of Aquaman's foes were Nazi U-boat commanders
and various Axis villains. The rest of his adventures in the 1940s and 1950s had
him dealing with various sea-based criminals, including modern-day pirates such
as his longtime archenemy Black Jack, as well as various threats to aquatic life,
shipping lanes, and sailors."
