Zihurios

Zihurios is an Elder Dragon introduced in Monster Hunter U. It travels slowly along the areas of the Hero's Valley in a similar style to Lao Shang-Lung and Shen Gaoren. It can release paralyzing gases from vents in it's back and legs.

Description
"A powerful dragon that wanders semi-aimlessly throughout the world. It will mindlessly charge through entire twons and cities without realising, only attacking when it feels threatened. Scientists detect that its movements are unpredictable and have no patterns"

Zihurios are rarely sighted due to their nature of being nomadic. They never stop in one location and will continue moving through inhabited areas. One such creature featured in Monster Hunter U approaches the Hero's Valley connecting Hakoru Village and the local Guild Hall, where it is repelled due to the extreme amount of defensive anti-dragon weaponry kept in the walls from Dragonators to Wyvernfire Cannons.

The common Zihurios has sandy-colored scales with a large crest above each of its eyes. The vents and pores on its back and its legs can release paralyzing gases at will, allowing it to take out large groups of animals without trouble. It is far more slender than Lao Shang-Lung, yet it chooses to leisurely walk around but has the energy and shape to move quickly when enraged. They have hard backplates which reduce damage taken.

They aren't limited to this color-some sport white or purple scales or have larger crests, yet the Guild doesn't yet consider these to be true subspecies.
