Copper is a naive thin-blooded vampire who knows very little of vampire lore. He asks the protagonist questions such as who the head vampire is and whether a full blood transfusion can return a vampire to humanity. It can be chosen whether to tell him the truth or lie to him in order to gain money. He believes killing the "head vampire" will return all vampires to humans and a nearby stake can be provided to encourage him to do just that and send him to LaCroix. Also, a blood pack can be sold to him under the pretense of it being unicorn blood, as he believes a blood transfusion could be the other answer to becoming human again.
