Darkseid, and yes, he is.
Darkseid is a New God.
When the Old Gods destroyed themselves in a cosmic war, the final explosion of their immense world sent a wave of energy across the universe that created the beings we call gods - Zeus, Odin, Indra and so on.
But the godworld itself reformed into two new words, and from it were born the New Gods. So they are like super-gods who live outside the normal universe. And Darkseid is the mightiest of them all, because he has possession of the Omega Effect.
