Galactus uses his power to shrink down into the size of Cooler. He can only use his power to alter his size and augment his speed and strength
Galactus can not fire energy beams: If he does he will loose energy (in-character trait)
Galactus has to fight for as long as he can before his power dissipates. How long can Galactus fight?
Geti Star is near by, but Galactus doesn't sense it because of Cooler.
