It is equipped with a sleeping sac that can put hunters and other monsters to sleep.
Hypnocatrice's Sleep Gas is capable of putting other creatures to sleep, including Velocipreys, Hermitaurs and even other Hypnocatrice. Compared to other Bird Wyverns, it has more control of its body movements. Its fighting style is very similar to the Yian Kut-Ku's, but much deadlier and more accurate. It has an attack where it jumps repeatedly at the hunter, attacking with its claws, inflicting surprising damage.
Hypnocatrice, true to its passive nature, doesn't tend to kill its foes. Rather, it prefers to put them to sleep and run from the fight. However, when enraged, it will put its enemies to sleep, then do everything in its power to kill its foe.
A rust-colored bird wyvern with beautiful tail feathers found mainly in forests. A highly pacifistic wyvern by nature, it breathes sleeping gas on its enemies and prey alike. Its strong, developed legs pack a serious punch, so be careful!
In Freedom Unite, its back feathers are rainbow-coloured.
Hypnocatrice in Frontier does not use the jump kick, but instead has an upward Sleep Gas attack that Hypnocatrice does not do in MHFU.
Hypnocatrice's only breakable part is its beak.
It probably got its name from 2 different words. One is "Hypnos" which is the Greek God of sleep. The other is "Cockatrice." The Cockatrice is a Wyvern with a rooster's head. We take "Hypno" from Hypnos and "Ckatrice" from Cockatrice and take away the "K" and we get "Hypnocatrice".
When in rage mode, Hypnocatrice's tail feathers will stand up more prominently, unless near death, when they lie flat.
Hypnocatrice was the target in the easiest quest of the PSN demo.
