Julius Benedict and Vincent Benedict are twins, the result of a secret experiment carried out at a genetics laboratory to combine the DNA of six fathers to produce the perfect child. To the surprise of the scientists, the embryo split and twins were born. The mother, Mary Ann Benedict, was told that Julius died at birth, and not told about Vincent at all. Vincent was placed in an orphanage run by nuns in Los Angeles and told his mother abandoned him. With no one but himself to rely on, Vincent escaped from the orphanage by seducing a nun and, later became an indebted, small-time low-life. Julius was raised on a Oceania island by Professor Werner, one of the scientists from the experiment, who put him through intense physical training and extensive study. Each twin was unaware of the other's existence.
