In his first appearance, a somewhat intoxicated Ben Donavan angrily attacked Luke Cage mistakenly thinking the "Hero for Hire" was involved with this date for the evening Mrs. Jenks. After Luke had soundly defeated Donavan, the two became friends and Donavan served as a competent lawyer to Cage. To repay Cage, Donovan performed legal services for him. At Cage's request, Donovan put a "tail" on the Hero for Hire that brought authorities onto the scene to help him subdue Billy Bob Rackham, Shades, and Comanche. 
Donovan later became involved in drug trafficing with the Maggia. Donovan had become bitter in life, even hiring a sniper to successfully assasinate a policeman who had previously arrested him. When he tried to steal a massive shipment of drugs from the cartel, he tried to enlist Cage to help him. However, Big Ben quickly betrayed Cage to the the Maggia organization. The Maggia, with Ben Donovan in tow, defeated Cage, chained him, placed him in a coffin and briefly buried him in at Resthaven Cemetary. Iron Fist and Thunderbolt arrived just in time to save Donovan from his gangland execution by the Maggia. After defeating the crime thugs, Donovan repaid the two heroes by immeidiately turning his pistol on the pair. Cage literally emerged from his grave to stop Donovan. The speedster Thunderbolt shot and quickly disabled Donavan right before the hero died of his lethal radiation poisoning.  Donovan is apparently still incarcerated.
