Powers: Leather can fly, generate destructive energy bursts and surround himself with an aura of what appears to be blue flame. He can also regenerate from injuries and appears to possess some degree of superhuman strength, easily besting Jakita Wagner in one encounter.
Bio: Formerly a daredevil, he seems to be the most active and visible member of the Four, often venturing along with their clean-up crews to take care of any problems. William Leather's mother, Miriam, was the wife of Bret Leather, The Dark Millionaire, one of the Century Babies and son of the Dead Ranger. However, Miriam cheated on Bret with a loan shark, William's biological father. Cheated of the awesome powers Leather would have passed on to his son, William joined Dowling. Leather was recently captured and placed in Planetary custody. Snow mercilessly tortures and eventually blinds him during an interrogation (Given Leather's regenerative capabilities, it may be assumed that this is temporary). Leather confesses to Snow that he has become more distant from and resentful of Dowling and Süskind in recent years, believing that they only allowed Leather and Greene to join them because they needed them to do their "dirty work."
