Monoblos are Flying Wyverns introduced in Monster Hunter.


Monoblos are large wyverns with a brown, rock-hard texture to their carapace, and very closely resemble Diablos. Unlike Diablos however, a Monoblos's head is akin to Ceratopsian's dinosaurs, namely a Styracosaurus, featuring a beaked mouth, a long, spiral, and pointed nasal horn, giving it a drill-esque look, and a large frill on the back its head, which, when enraged, gains several red markings. Additionally, it is adorned with spikes of various sizes. Monoblos has a pair of small yellow eyes with vertically slit pupils. Its back also features a frill-like carapace. The tail club is more like a mace compared to a Diablos's, lined with four spikes on each side, and a single one at the end.


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.

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.
