Those books called The Lion King Six New Adventures where the origins of Scar are explained all aren't canon to disney because an fanauthor Alex Simmons wrote the story and disney only approved of publishing it by giving the license to do so. Therefore all the events and characters like Kopa are only semicanon to the Lion King universe.
