Creatura are a species almost like Homunculi. Creatura are created when a human creates a philosopher's stone with themselves inside the circle. Since the alchemist creating it is the one well, creating it (no duh), the souls are not in the form of a philosophers stone, but rather injected into the alchemist. This is different from Van Hohenheim, because the souls remain active, and like a Human-based Homunculus (such as King Bradley), and only one soul remains. Every time, the original alchemists soul and body are destroyed. A new body forms from the old one. Some people call Creaturas "Phoenixes" because of this. After the destruction of the Homunculi, Father, who survived, infuses the same emotions (the seven deadly sins, because when the homunculi died, the emotions grew back within Father) after the old body dies and before the new body forms. However, there are eight Creatura in all. Pride, Wrath, Lust, Envy, Greed, Gluttony, Sloth, and a newer, more recent "evil emotion" (not a deadly sin) Evil.
