Doomsday vs. Darkseid

I thought the all powerful warlord was Mongol.

Racist Game = Pool. WHITE ball push COLORED balls back into holes. BLACK ball out = you win.

Darkseid would win. Not even superman can kill Darkseid, its been
stated clearly that Darkseid's only weakness is a special substance called Radion (spelling?).

I would dare say that the only thing that can actually KILL Darkseid would be supreme beings like Galactus who has the power to actually disolve matter down to a sub-atomic level, in which Darkseid would have great problems staying alive.

OP, the two have fought once in a comics storyline called Hunter Prey. Google it or buy it online---it's a very fun read! Someone here already covered the premise of it, whereas also Superman examines whether he can stop Doomsday and has initial hesitations over facing off against him again. Doomsday ends up on Apokolips thanks to two space explorers who mistake his makeshift meteoric coffin as a piece of profit. Then once he ends up on the ship, killing everyone onboard, he lands on the fiery planet picking up murdering everyone in his path like on Earth. Darkseid more or less says that enough is enough and has to take things into his own hands and blindsides the monster with his omega beams. Those having decimated everything in existence they hit to ash, Darkseid was confident he had destroyed the monster. On a personal note, I laughed the first time I read it when as Darkseid walks off, Doomsday easily gets up from the wreckage he was blasted away into and beats Darkseid to a pulp with the ruler exclaiming "It's true what the legends say--YOU ARE beyond death!".

He's beaten so badly Superman was tempted to let him die. Then he realized that the people of Apokolips, as sadistically despicable their quality of life was at Darkseid's hand, ironically needed him so he repaired him with the Mother Box device.
