That being said, there is another slight possibility to consider. It's a very obscure character, from back in my day, but the description seems to fit perfectly: predates the Universe, too powerful for even Thor and Odin to take down, and his main power involves darkness.
The Dweller-in-Darkness first appeared in Thor comics; and later became a recurring enemy of Dr. Strange. Which would also lend credence to the Dr. Strange casting rumor.
He "feeds off of fear"?
I'd prefer a character not paralleling any aspect of the failure that was the Green Lantern.
