The Hom Dai
The worst of all ancient Egyptian curses, the Hom Dai's feared to a degree where the Egyptians refused to use it. It's said that when a victim of the Hom Dai is resurrected they'll become a walking plague and a threat to humanity; they won't sleep, they won't eat, and they'll never stop until the world is destroyed.
In order to fully regenerate a victim of the Hom Dai must suck the life of those who opened the chest containing their canopic jars. When they're not regenerated they will fear cats, but once they become regenerated they'll fear nothing, and they can only be killed via the Book of Amun-Ra, quite similar to how they can only be resurrected via the Book of the Dead. Their powers grow with every resurrection.
