Darkseid has a chance here, but i'm not certain just how much. One thing is for certain and that is Tyrant wins this. The only thing that managed to kill him in the end was the ultimate nullifier.
Superman countered the omega beams so can tyrant. Mr. M wasnt affected at all with the omega beams. As i recall darkseid tried that same move on Galactus and didnt even sratch him.
Galactus took a hit from the Omega beams, and wasn't erased to add to it Galactus was weak, if you notice that the story was called "The Hunger". With this being said, if Tyrant was at optimal strength Darseid doesn't stand a chance.
The Omega Beam thing sems to be a cheesy deal unique to the DC universe, and how Darkseid ties in with the Source.
It should not be used, or given the same properties when dealing with high-level beings outside the DC universe.
As a matter of fact, I think the same thing about some Marvel stuff too. Like, I don't think Cosmic Cube stuff should have the same effect in DC.
Heart of the Universe, would not be the same if it was brought into DC.
And, I definitely don't think Omega Beams should automatically be said to be able to erase high-level beings.
That is just cheesy.
If you use that kind of logic, then it can be said that the Destroyer Armor will beat Darkseid easily. Why? Because he has disintegrator beams. What do they do? They disintegrate stuff.
So, one shot at Darkseid will do what? Disintigrate him.
That simple. Right?
first off when he fought galactus that doesnt count, galactus is an essential to the universe, and that cross over isnt even canon.
Superman didnt conquer them he is protected by the source is all thats why the omega effect doesnt work on him they worked on orion for crying out loud.
the omega effect has hurt beings like anti-monitor and also spectre which are above tyrant.
Mr M why he wasnt effect is unknown sounds like PIS since even spectre gets hurt by them
When somebody gets hit with the omega beams it doesn't necessarily means that darkseid will erase them. Omega Beams can be use for many purposes , teleportation, force blast, resurrecting the dead, heal, disintegration, etc.
