The Daemon Ritus is the key to conquer Earth by the hands of ancient demons, after completing the evil "Darkopolypse Ritual". Scrappy-Doo who was changed by the Daemon Ritus' supernatural magic, used the relic to control the demons, morph into a powerful giant monster, and try to destroy Mystery Inc., with obvious failure.
