Originally from ancient Rome, Marcus had long been an actor in the theatre. During the early 1600's, he fell in love with a woman who eventually learned that he was an Immortal and betrayed him by telling others. He was burned at the stake, and he later killed the woman as vengeance. Ever since then, he has killed other women who remind him of her, all having blond hair. He was a serial killer known as "The Scalper" in the 1920's and killed 10 women in Seacouver before his friend Duncan MacLeod stopped him.
