What Atlantis is
Bill Everett created Marvel’s Atlantis alongside Sub-Mariner in Marvel Comics #1 (October 1939). The framing positions Atlantis as an undersea kingdom predating Marvel’s Silver Age, with Namor as its half-Atlantean half-human prince. The kingdom’s relationship with the surface world is hostile from the start; the Atlanteans blame surface humans for environmental damage to their undersea environs.
Stan Lee and Jack Kirby revived Sub-Mariner in Fantastic Four #4 (May 1962). Atlantis in the post-FF #4 era is in a state of recovery; H-bomb tests during Namor’s amnesiac period damaged the kingdom significantly. Subsequent decades have featured multiple Atlantis destruction-and-rebuilding cycles.
The MCU adapted Atlantis as Talokan in Black Panther: Wakanda Forever (2022). The change preserves the structural function while giving the kingdom a Mesoamerican-derived cultural identity rather than the Greek-mythological-derived comic original. The MCU framing has been received well; Tenoch Huerta’s performance was widely praised.
Collector context
Marvel Comics #1 is the canonical first-appearance key for Atlantis (Marvel). The book is one of the highest-value Golden Age comics; CGC 9.0 and above is in the seven figures. Atlantis’s first-appearance value is folded into the Sub-Mariner first-appearance value.
