Vincent Velcoro was born in 1911 in New York City. On reaching adulthood he enlisted in the U.S. Army. Caught betraying his country and found guilty of treason, Vincent Velcoro was offered a choice: either accept a 30 years sentence, or submit himself to radical experiments to help him become a secret weapon for the Allied forces. Naturally he chose the latter. For 6 months he was injected with a compound made with experimental chemicals and blood extracted from the New Mexican vampire bat . Thus, Velcoro was transformed into a "scientific approximation" of a legendary undead vampire.
Sgt. Velcoro served in an experimental U.S. Army commando unit known as the Creature Commandos, alongside two other surgically-altered soldiers, Pvt. Elliot "Lucky" Taylor and Pvt. Warren Griffith, under the command of Lt. Matthew Shrieve.
