Operation Clean Slate was a plan, formulated by Demona, to destroy all of humanity.


Dominique Destine employed Anton Sevarius to develop a Carrier Virus for Nightstone Unlimited called the CV-1000 whose official purpose was to create cures and vaccines as powerful as the diseases they fought. The true purpose of the carrier virus, however, was to be combined with the D/I-7 stolen from Xanatos Enterprises to create a plague powerful enough to destroy all of humankind. In order to protect the gargoyle race, Demona planned to use the Praying Gargoyle to save them from the virus. Goliath foiled the plan when he smashed the statue, thereby putting himself and all of his species at risk.
