Desak VS Superman
In the Red Corner, we have the 6' 8" God Slayer known as Desak, he possess superhuman strenght sufficient for stay head to head with the Destroyer Armor powered by the soul of the Designated, an entity equal if not superior to Odin, his resistance to injury is also great, and he's immune to any kind of godly power, and he can absorb, redirect or send them back, he was able to withstand with great amounts of Odin's Power blasts from Thor without being injured.He was able to substain attacks from Magni, God Of Strenght and son of Thor that was also using Mjolnir(but he hasn't got sufficient experience to use Mjolnir at full power)He can also fly at warp speeds, and shoot energy blasts from his axe and his eyes.He also carry a dagger a shield and a sword he use with great knowledge.To finally kill him Thor used Mjolnir to magnify the Odin's Power and behead the God Slayer.
In the Blue Corner, we have the 6'3" Kryptonian known as Superman, we all know his amazing strenght and invulnerability, as his speed, sufficient to follow the Flash, also he possess the ability to project powerful heat vision, and he also possess hyper-sensess.
Considering that Desak is for Thor what DoomsDay is for Superman, i give him great chances, yes Supes is in a god-like status with his powers, but he's not a diety, so Desak may be able to deflect his attacks but he hasn't the same immunity he can possess against a god.
Anyway Superman has experience on his side, yes Desak has slay hundred of gods, but the Man Of Steel can get advantage through forcing Desak fighting into the sky, cause it seems he's not a great expert aerial combatant as Supes.Anyway this is a close match, maybe Kal El would with Desak or he would finally outsmart him and kill him, but it's a close close match.
