Abraham

Abraham 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. Forced to abandon the site by the outbreak of the American Civil War, the Society never found occasion to return for Caul, and there he stayed until he was found by workmen in November 1978.

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).
With his second transformation to his current form, Abe's strength, agility, and speed has significantly increased, performing feats never seen before by him. His speed is at its peak underwater. Lately, by his own admission, Abe has been having an intuition of danger, always knowing something bad is going on before it happens with little to no proof.
