Rare Species, Variants, or Named Variants.
subspecies is an alternate form of a monster. These monsters usually feature an alternate color palette and often boast different anatomical features and abilities from the common species. Subspecies can inhabit similar environments as the common species, but they can also sometimes be found in completely different locales, depending on the species of monster. Though subspecies are strong and rare, Rare Species are far stronger and rarer.
