Henry Hawk was a criminal hand picked by the Organizer to join his Ani-Men. The Ani-Men were soon sent against Daredevil by the Organizer, after he had crossed the Organizer's plans on several occasions. After implicating Daredevil in a bank robbery, the Ani-Men were next sent to kidnap Debbie Harris. They were defeated when Daredevil infiltrated their headquarters using Frog-Man's costume.
Later, Hawk escaped from prison alongside his fellow Ani-Men Ape-Man and Cat-Man. They started working for the Exterminator as the Unholy Three. They were once again defeated by Daredevil and on another occasion by Daredevil and Spider-Man.
Later, the Ani-Men were employed by Count Nefaria, whose scientists subjected all of them (including Hawk) to experimental processes which gave them super powers duplicating their artificial ones, but animal like appearances. The Ani-Men fought the X-Men at the Cheyenne Mountain missile base, but were defeated. They later apparently lost their powers and went back to using their original equipment, but continued to work for Nefaria, attempting to kill Tony Stark at his command and fighting Iron Man. Hawk and the other original Ani-Men were all apparently killed during this incident, when the assassin Spymaster blew up Nefaria's base with the Ani-Men inside it.
