They are solitary Dinotrux with no fear against T-Trux and Scraptors, prefer being alone and known to be drifter, stubborn and somewhat brave during fights. But they do have common sense to retreat and are experts of fire fighting tactics. There are however, rare cases of Hydrodons who are skiddish if picked on long enough. Some Hydrodons do live in herds, providing more protection for the group.
