- MHGU Description

Yian Kut-Ku is a Bird Wyvern first introduced in Monster Hunter. They can be seen inhabiting a wide variety of locations such as the Verdant Hills and the Old Volcano.

Physiology

The Yian Kut-Ku is characterized by its large, fan-like ear frills that unfurl when excited and enlarged lower bill. They have a large, yellow beak with a pink stripe running central down the length of the upper beak. The lower jaw of its beak is significantly larger and bulkier than the top jaw. Yian Kut-Ku's body is covered in orange-pink plating and beige scales. Its wing membranes are deep blue and its eyes are bright yellow. These wyverns are small and relatively light, making them quick and agile. They have an extremely powerful sense of hearing, thanks to the large frills circling their ears.

Behavior and Abilities

The Yian Kut-Ku is capable of moving at high speeds thanks to its light weight and small stature. It is also able to produce flaming projectiles coming from its flame sac, which can be shot from the mouth at attackers. It can spew three flaming projectiles at hunters when enraged and move faster.

A somewhat temperamental, skittish, and inquisitive wyvern. Yian Kut-Ku have a tendency to want to appear bigger than they really are by spreading their wings, flaring out their ears, and squawking loudly. They are generally insectivores, preying on Konchu and other Neopterons as a main part of their diet.

General Notes

• The name "Kut-Ku" may come from the word "cuckoo" for its bird-like characteristic and appearance.
• The large frills or discs around its ears function similarly to the facial discs of owls, enhancing their hearing.

Monster Hunter Freedom Unite

There is a quest called "At Birds Hill..." which requires players to fight an extremely small Yian Kut-Ku at the Forest and Hills zone, which is most-likely a young Yian Kut-Ku. It has a different voice due to its miniscule size, yet its fireball attack increases in power and explosion radius, this may be because it doesn't have very good control over its Flame Sac.

Yian Kut-Ku can be sometimes be seen drinking from the ponds in Areas 9 and 10 of the Forest and Hills.

Monster Hunter 4 Ultimate

The Yian Kut-Ku has 4 toes while in previous generations, it had 3 toes.

Yian Kut-Ku will prey on Konchu to regain stamina.

Yian Kut-Ku is now capable to release 2 fireballs instead of 1.

While low on stamina, Yian Kut-Ku won't be able to shoot fireballs, and its beak will get stuck in the ground when it performs its pecking attack.

In G-Rank, Yian Kut-Ku can dig up Konchu and throw them at the hunter.

Monster Hunter Frontier

Yian Kut-Ku can be a pet, its favorite foods are insects and worms.

Monster Hunter Online

This monster is unlocked at Level 10.

Yian Kut-Ku's ears can be broken twice.

Yian Kut-Ku's ears will fold back when affected by a Sonic Bomb and are not used as a weakness sign.
