The 
Nue (鵺, 鵼, 恠鳥, or 奴延鳥) is a 
legendary yōkai or 
mononoke (momonosuke)
"Nue" (鵼) from the 
Konjaku Gazu Zoku Hyakki by 
Toriyama Sekien
In the 
Tale of Heike, it is described as having the head of a MONKEY (luffy), the legs of a TIGER (Zoro), the body of a DOG (Yamato) and the front half of a SNAKE (Momo whos is a dragon. With the dragon having history with the snake in mythology) for a tail. In other writings nothing is stated about its torso, so it is sometimes depicted to have the torso of a tiger. The 
Genpei Jōsuiki describes it as having the back of a tiger (ZORO), the legs of a tanuki (Yamato since she is a transforming dog), the tail of a fox, the head of a cat, and the torso of a chicken (MARCO) due to its appearance, it is sometimes referred to as a Japanese 
chimera.

It is said to make terribly eerie bird cry "hyoo hyoo" noises that resemble that of the 
scaly thrush. In the movie 
Akuryōtō (originally by 
Seishi Yokomizo), the catchphrase "nights where the nue cry are dreadful" refers to this fact. The nue is also said to have the ability of shape-shifting, often into the form of a black cloud that can fly 
[2]. The yokai is also thought to be nocturnal as most of its sightings happen at night. Its name written in 
kanji translates to 
night and 
bird.
