The gods and goddesses are Soul Armor. So when the aliens inhabit the bodies of the gods, they do so like the Intellect Hunters, the Scree, and the Valtay. The aliens are wearing the gods like clothes. That means they can, in theory, be removed with a successful cast of any spell designed to remove biological armor, such as Take That Shit Off and Laundry Day. You’d have to first defeat the invulnerability, of course.
