So...

(note that I'll blank this on Monday if the trade isn't completed)

Physiology: I'm giving this one to Cthulhu, personally. His general physiology itself is generally enough to fray an onlooker's sanity. Further, he has omniscience; knowing everything means you know how to counter everything. Darkseid's got superhuman physology and limited invulnerability, but neither of those are going to be effective against someone who knows exactly what your weakness is. And Cthulhu will know; knowing everything is literally the definition of omniscience.

Powers: This one's also going to Cthulhu, thanks to mindmash. Darkseid's powers and abilities are more than likely nullified by Cthulhu's phase shifting as well as the omniscience outlined above giving the Great Old One information on Darkseid's weaknesses. The Omega Beams are likely Darkseid's greatest weapon here, as it can probably be used to fight off Cthulhu's backup, and are also the only things that stand a chance of harming the monster. While Cthulhu's size makes him a prime target, his ability to literally spread violent insanity makes it less likely for Darkseid or his backup to function.

Backup: Goes to Cthulhu again. While The Deep Ones are simple mooks that will get slaughtered by the Parademons, the Star Spawn will turn the tables quite easily, thanks to having lesser forms of Cthulhu's powers. At the absolute best, the Parademons will suicide bomb the Star Spawn armies once they've determined combat will do no good. At worst, Cthulhu and the Star Spawn's insanity inducement will cause the army to turn on itself.

If it's not already clear from my edges, I think Cthulhu will absolutely destroy Darkseid and his horde. Since this is an army-on-army fight, the most powerful factor here is morale. Darkseid and his followers are fighting in R'lyeh itself, a city that does not conform to Euclidean geometry and is treacherous to navigate, as its appearance does not match the reality of the terrain. Darkseid and his minions are fighting beings that drive others mad in a place that drives others mad; it won't be long before the army breaks - either mentally or in retreat. Powerful as Darkseid is on his own, he can only fight so long against both an army of Star Spawn and Cthulhu itself.

Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn. And Darkseid will learn to never interrupt a Great Old One's beauty sleep.
