Nulliblos (ヌリブロス, Nuriburosu) is a Flying Wyvern.


Nulliblos looks similar to its relatives Diablos and Monoblos with a tan armored shell covering its body. It has a short, compact frill that is lined with spikes and a beak-like mouth with fang-like protrusions. Nulliblos's tail ends in a spherical club that is covered in small spikes. What separates Nulliblos from its relatives is that Nulliblos lacks horns. It is also noticeably smaller than its cousins.


Nulliblos are adept diggers and can burrow underground and travel through the sand in their desert environment. They can fly using their thick, muscular wings, another trait that separates them from their relatives. Their roar is incredibly loud and is used to stun hunters and predators.


Nulliblos are quite docile compared to the highly aggressive Diablos and Monoblos. However, they can become equally aggressive when faced with a predator or Hunter.


Nulliblos only lives in the Desert, Dunes, and Sandy Plains. They can be seen in the Everwood at times.

Nulliblos is a Flying Wyvern that is closely related to Diablos and Monoblos. It also has a closely related Subspecies called Gray Nulliblos.

Habitat Range

In the Old World, Nulliblos inhabit the Desert, Dunes, Old Desert, and some parts of the Everwood.

Ecological Niche

Nulliblos, like its cousins, are herbivorous wyverns that feed on different types of desert vegetation, most commonly giant cacti. Nulliblos are always on the look out for these rare and succulent plants, which leads to frequent territorial disputes. Nulliblos occasionally come into contact with large predators such as Tigrex, Rathian, Seregios, Kuarusepusu, Deviljho, Glavenus, Sand Barioth, Akura Vashimu, Nibelsnarf, Odibatorasu, Hyujikiki, Teostra, and Kushala Daora.

Biological Adaptations

Nulliblos has the ability to burrow underground, just like its relatives. They can dig underground at over 50 miles (80 km) per hour, which causes tremors. Nulliblos and its kin are well-known for their sensitivity to high-pitched sounds due to their well-developed sense of hearing. They can also produce the same ear-splitting that can be heard from miles away. Nulliblos lack any kind of breath attack, but they more than make up for it with bone-crushing ramming attacks, courtesy of their powerful legs and rock-hard skulls. Their muscular wings also make them adept fliers and can fly for hours without having to rest. Its thick tail serves as a club for self-defense, capable of breaking rocks, and its hard shell is perfect for protecting Nulliblos from most attacks. Their frills are used mostly for thermoregulation, keeping it cool in its dry, arid environment. It also serves as a form of courtship display.


Nulliblos are nowhere near as aggressive as its relatives and would much rather avoid conflict. However, they can become just as aggressive when confronted by an enemy. Males use their frills as a form of courtship display; the larger a male's frill, the better chance he has at attracting a mate.


  • Nulliblos is inspired by hornless ceratopsians such as Protosaurus, Psittacosaurus, and Yinlong.
  • Nulli- is a Latin prefix meaning zero, as Nulliblos has no horns.
  • Its head, back, and wings can be broken. The tail can be severed.
  • When low on stamina it will trip after charging.
    • It will feed on cacti to recover stamina.
  • Nulliblos's roar requires HG Earplugs to block.
