Hypnocatrice, The "Sleep" Bird Wyvern

Hypnocatrice (Japanese name: Hypnoc) is a red feathered Bird Wyvern very similar to the Yian Kut-Ku. It made it's first appearance in Monster Hunter Frontier, and also reappeared in Monster Hunter Portable 2nd G and Monster Hunter Freedom Unite This is evident in it's same body structure and attack pattern as the Kut-Ku. Hypnocatrice is termed as a 'sleep-based' monster; it's projectile attacks cause enemies to fall asleep when hit. It's attacks are also very powerful and quick, creating difficulty when dodging.

The Japanese name "Hypnoc" is a play on the word "Hypnotic" for it's sleep-inducing abilities. As such, the correct Japanese spelling of it's name is in fact "Hypnoc".
