Abraham Sapien, born Langdon Everett Caul, is a fictional character introduced in the comic book series Hellboy, created by Mike Mignola. He takes his name from "Ichthyo sapien", the fanciful species designation chosen for him by his colleagues in the 19th-century Oannes Club, and from Abraham "Abe" Lincoln, on whose assassination date the Oannes Club abandoned Abe's body, leaving only a cryptic note as explanation, in a suspended animation tank beneath a Washington D.C. hospital. He is occasionally referred to as an "amphibious man." As well as regular appearances in Hellboy and B.P.R.D., Sapien has also starred in his own comics, with trade paperback collections and omnibus editions including The Drowning, The Devil Does Not Jest and Other Stories, Dark and Terrible and Lost Lives and Other Stories. Fictional biography Sapien began his life as Langdon Everett Caul, a Victorian scientist and businessman who became involved with the Oannes Society, an occult organization who believed in life and all knowledge having come from the sea. After retrieving a strange jellyfish-like deity from an underwater ruin, Caul and the other members performed an arcane ritual that inadvertently ended with the creature's release and Caul being turned into an ichthyo sapien. Believing him to be Oannes reborn, the society sealed the developing icthyo sapien's body in a tube of water in the hidden laboratory beneath a Washington, D.C. hospital until such time as he was fully formed.

With no memory of his life before, the icthyo sapien received a new name from a piece of paper attached to the tube, dated the day of Abraham Lincoln's assassination (April 14, 1865). Abe Sapien was taken to the Bureau for Paranormal Research and Defense (BPRD) for a grueling round of research by curious BPRD scientists and was saved from vivisection by an empathetic Hellboy. Thereafter, Abe entered the ranks of the BPRD as a valued field agent, embarking on his first mission with Hellboy in 1979. At Cavendish Hall, during the climax of Seed of Destruction, Sapien was possessed by the spirit of long-dead whaler Elihu Cavendish. Cavendish was a contemporary of Langdon Caul, who killed the mad monk Rasputin, foiling his plans to unleash the Ogdru Jahad to
