Mort Coolidge was a small-time Gotham City criminal who used his limited telekinesis for ill-gotten gain.
Relocating to San Diego he was submerged along with countless other citizens. Coolidge discovered that his abilities to control water were remarkably more powerful. Consolidating the surviving members of the Sub Diego underworld he established himself as the crime boss called the Eel.
