Michael Lane was once an officer of the Gotham City Police Department. He was once part of an initiative to create the "ultimate crime fighter"; however, it drove him criminally insane. Once apprehended by Batman, he confessed his sins to a priest of the Order of St. Dumas. He was then recruited by the Order to become Azrael, their divine cruzader. Lane has studied Batman's techniques and tactics more than anyone else, and waits patiently for his time to replace Batman and bring true and divine justice to Gotham.
