Mind controlled Daxam (GDS) vs Sinestro Corps & DC earth

Darkseid has controlled Daxam (Great Darkness Saga) and is headed straight for Sinestro and DC earth. Do they have any hope of surviving?

Probably not.

i just cannot fathom the sinestro corps/DC earth fairing well against 3 billion superman-level beings..

Nope. Even the SCW AM could only take on four or five PC Daxamites top, and there's 2 billion of them. I don't think the combined forces of DC Earth and Marvel Earth could beat them.
