A mortal from Paris, he ran a string of call girls including Tessa Noël's old friend Elaine Trent. It was one of Battini's girls, Claudine, who fatally stabbed the borderline psychotic and latent immortal, Alfred Cahill. After Cahill's revival into immortality, he thought it his mission to destroy sin and vice, and began hunting. He killed the girl who had stabbed him, Elaine's client, and Battini's driver. When Elaine was convinced that she, too, might be in danger, she agreed to leave the city.
