Mogo, the living planet Green Lantern has to destroy Apokolips and New Genesis.
They have 1 hour advance knowledge of his approach.
Mogo gets all his post-crisis/nu52/rebirth feats.
New Gods are all post-crisis.
1: Normal size stuff.
2: Darkseid and Orion only vs Mogo but they are at full size 4th world status - unaltered by boom tube shenanigans.
