Twilight of Throneworld
Since his universe had ended and this one had begun, Galactus had fed.  His hunger had driven him, given him cause and purpose throughout the universe, in a way that the mortals who inhabited it would never understand.  He did not feed out of malice or even joy, he simply fed.  They tried to give motivations for him, but he was beyond their understanding, as necessary an element to the cosmos as Eternity and Death, the balancing point between those two extremes.

His feet touched the ground of Throneworld, and the whole of the populace seemed to tremble in fear.  Sharra and K'ythiri were called out for, but the gods of the Shi'ar would have no place here.  Here was only the Great Devourer of Worlds.  Here was only Galactus, assembling his terrible machine with which he would consume the lifeforce of the planet.

Galactus was.
