"Leviathan is everywhere. Leviathan is everyone. And Leviathan is coming."
Margot Morrison to Eve Teschmacher[src]

Leviathan is a global secret terrorist organization operating on Earth of Earth-38.


Leviathan was formed by the former leaders of Jarhanpur, not long after their arrival on Earth brought about the extinction of the dinosaurs and the rise of humanity. For eons, one of the leaders, Rama-Khan, was in charge of protecting the Earth from humanity's self-destruction since the beginning of time.

He and Leviathan have monitored the Earth and kept humanity at bay through multiple extinction level events, like Noah's Flood, the destruction of Pompeii, Antioch, the Yellow River flood, and the Bhola Cyclone. By the modern times, they have become a powerful hidden terrorist organization and who's influence reach beyond even Obsidian North and L-Corp.

As a member of Leviathan, Eve Teschmacher was tasked with working for Lex Luthor in order to "move the needle". However, she was unsuccessful in helping him complete his mission, leading to her being found once trying to escape.[1]

Leviathan started spending large amount of funds to hire contract killers to carry out their wishes.[2] They hired Caroline O'Connor to kill Niles Jarrod and Dr. Andrew Stern, the latter of which she did unsuccessfully.[3] Their next target was Elena Torres, they sent Breathtaker to kill her but she was stopped by Supergirl and incarcerated.

Leviathan recruited individuals like Andrea Rojas and Eve who were broke and desperate for money. They use this organization to bend them against their will and in return to help them out financially.

Behind the scenes

  • In the DC comics, Leviathan is an organization founded by Talia al Ghul, upon leaving her father, Ra's al Ghul's League of Assassins. The organization was later taken over by Mark Shaw, a former US marshal and member of the Manhunter Cult, who led a coup and overthrew Talia by taking advantage of the syndicate war the organization was in under her leadership. Shaw also took the name "Leviathan" as his alias.
  • Also in the DC Comics, the organization led by Gamemnae is called League of Ancients. This ancient group that existed thousands of years into the past, included seven members like Rama Khan, Tezumak, and Sela, all from different places of origin on Earth. Each member represented a different place and culture on Earth. Its seven members were brought together by Gamemnae's scheme to defeat the Justice League in the present time, as the heroes were viewed as a threat.
