The Deproose live in large herds on the icy planet of Ontarost, grazing on the various flora that have evolved to specifically live in the harsh cold climate. While they are not a smart species, they are highly loyal and incredibly large and strong. Ontarost has vast resources that are left alone even by the powerful Incursean Empire, who are highly intimidated by the Deproose's size and massive population that consists of millions of Deproose.
- Fully grown Deproose are taller than a normal sized Vaxasaurian.
