Brute Wyverns are a class of monsters introduced in Monster Hunter Tri. They are flightless, almost dinosaurian creatures that attack mostly through charging and use of their heavy tails, which they use to balance their bodies. Only two species of Brute Wyverns return to Monster Hunter 4 Ultimate , Brachydios, who has actually mastered the use of its forearms to punch, and Deviljho, the endlessly hungry nomad.
