The Overlords are an alien race. They come to Earth in the late twentieth century and take control of the planet. They eliminate disease, war and hatred, and create a world government that broadens into a utopia. This peaceful mission is overseen by Karellen. Physically, the average Overlord is much taller and more built than a human, with large wings, horns on its head, and a barbed tail.

The alien being that the Overlords serve. The Overmind is not a creature of matter; it is not solid. It is a kind of "collective conscious," a massive entity of thought and energy that crosses the galaxy, and perhaps the universe, trying to "increase its awareness of the universe." It incorporates entire races into itself, eliminating their individuality while greatly enhancing their power.
