Monoblos are Flying Wyverns introduced in Monster Hunter.

MH4U-Monoblos Render 001


They have a brown, rock-hard texture to their shell. There is a subspecies of Monoblos known as the White Monoblos. These are generally larger in size than their sand colored counterparts and seen as more dangerous by hunters. Ironically, whilst their ear splitting roar is the bane of hunters, they are weak to Sonic Bombs while digging through the ground and not in Rage Mode.

The Daimyo Hermitaur uses a Monoblos skull to protect its vulnerable back when it matures into a fully grown creature. The Plum subspecies uses a Diablos skull for the same purpose.


While they have no breath attack, their roar is considered a lethal weapon itself. They are also very physically capable, able to fight off hunters with horn-thrusts and tail-swings. Being able to tunnel beneath the sands of the Desert also means they can sneak up on any potential threats.


Monoblos are aggressive, and will attack Hunters on sight. When suitably enraged their crown will become inflamed with red streaks. They are quick to anger, and will move faster and hit harder while enraged.


Monoblos have only been spotted in the Desert, Old Desert, and Dunes regions. They have also been seen inhabiting the arid areas of the Everwood.

Other Non-Subspecies Forms

In Monster Hunter Frontier 10.0, HC Monoblos was released. Its attack power and speed are increased; its digging attack is much faster; it can perform a ground-slam immediately followed by a powerful horn thrust; and finally, it can perform a tail whip whilst sliding forwards.

HC Monoblos' horn appears longer and its body and tail are more spiky.

General Notes

  • The Monoblos' head bears a great resemblance to that of the prehistoric Styracosaurus.
  • Many of Monoblos' attacks are identical or similar to that of the Diablos.
  • Along with the Diablos, Daimyo Hermitaur and Shogun Ceanataur, the Monoblos can destroy a Shock Trap by burrowing up from beneath it.
  • If not in Rage, when they dig underground, a Sonic Bomb can be used to produce an effect similar to "Pit Trapping" for around five seconds.
  • When a 'blos wyvern charges into a wall or ledge, their horn(s) causes them to get stuck in it, after two or three times the horn(s) will break and become an award item at the quest's end. Once its horn(s) has been broken, that individual 'blos will not get stuck in any wall or ledge again. Their tails can also be severed from the body.
  • When a Monoblos is ledged for the first time in the battle, it will yield a 'shiny' item. This can either be 'wyvern tears' or another item of that ilk. However it is possible that the Monoblos may drop a rare 'Monoblos Heart'. How the Monoblos's heart is dropped is a mystery.
  • Monoblos' roar requires HG Earplugs to block.
  • Monoblos and its subspecies are exclusively encountered in singleplayer settings.
  • The Old Desert's music theme "真紅の角 (Crimson Horn)" is made for Monoblos.
