Name: Digimon Multiverse
Scale: Depending on the individual world-pair, but usually interplanetary war, ranging to interdimensional universal conflicts.
Setting: Everything is digital. Usually the digital world is engaged in constant combat as digimon eat one another in order to digivolve, controlled from a distance by the Digimon Gods (Ygdrassil and the like).
History: Depends completely on the individual world-pair.
Power Scaling: Universe Busters at max, although none that will ever occur in the roleplay in any way.
