UMA

UMA (ユーマ), short for Unidentified Mysterious Animals, are creatures created by God that The Union must face as apart of Apocalypse's Quests.

Overview
UMA are large, otherworldly looking creatures that embody a specific rule that has been imposed on the world by God. Each has a radius in which they can enforce their rule upon anything that enters, and each UMA has abilities unique to it based around the rule it embodies.

UMA can also create offspring. The Union refer to these as "Juniors". These offspring can be created when an UMA enforces its rule in a certain way, with one such example being the zombies made by Spoil.
