[DC] what exactly is the Omega effect?
gpt
Long story short, it's the source of Darkseid's powers. You can think of it as similar to the Odinforce (or later the Thorforce) in Marvel.

DC says that the Omega Beams he creates using the Omega Force are made of entropy, but it goes beyond that. Darkseid can do pretty much anything using them. The Omega Beams unerringly search out their target, and when they hit, they can destroy the target, erase them from the timeline, or turn them into a tiny little ball for safekeeping.

Darkseid claims that no living thing can survive the direct, full force of the Omega Effect, but Doomsday and Superman have both tanked shots ... though they were staggered by the blast. It's possible that the Omega Effect *could* kill them, but it seems like this would tax Darkseid to his limits.
