En.ki and his cohorts do not have an avatar—they can’t form an avatar by themselves and are therefore stripped of all their creativity. Instead, they started taking loosh (soul energy) from us humans to sustain themselves, just like an addict needs their drug to be able to function. They also created artificial bodies, using advanced technology, so they could move around. We could say that their “physical” bodies are artificial intelligence. Still, these bodies are of another density than ours and can’t function in our density. If the Overlords want to mingle with us, they need to take a human body, just like us. This, they have done many times in the past, and some of them still do. Marduk is one example.
