Animal naturally occuring in its world.
Creature created through bioengineering that looks like it could be a Native animal or plant, except they're not natural life forms.
Computerized being made entirely out of metal. Essentially, a robot.
Bioengineered abomination. They come in two types: Organic and Bionic. Organic are completely flesh, while Bionic is combination of flesh and machine.
My rendition of a mythological animal.
Demons, spirits, gods, and the like.
