WMG / Shin Megami Tensei Liberation: Dx2

Dimensional Odin isn't just using the design from Apocalypse, he's from Apocalypse

In the event, he says that after Vantias destroyed most of humanity, the rest of humanity is divided into camps, and he wants his camp to win. He adds that there are other people who use demons like the Liberators, but aren't called Liberators. If you interpret Vantias as YHVH nuking the world, then the camps are the factions, Odin's faction is the Divine Powers, and the demon users are the demon summoners.
