Strength is ranked in the order of 5 < 4 < 3 < 2 < 1.

Depending on their intelligence and spiritual power, their physical transformations manifest in completely opposite ways. They are divided into Lower, Intermediate, and Superior monsters, with Lower being the weakest and Superior being the strongest.
