Weavile is a bipedal, weasel-like Pokemon with a pale gray body and several feathery areas. It has a bright red crown and collar made of wide feathers, and a single, thinner feather on each ear. The ear feathers are smaller on a female Weavile. Weavile has two tail feathers and three claws on each paw. There is a yellow, oval marking in the center of its forehead. Its eyes are red with three eyelashes, and four fangs protrude from its upper jaw.
Weavile is devious and intelligent. It usually lives in cold, icy areas where it forms small packs. A pack of Weavile uses teamwork to take down its prey. It can communicate in the form of carving patterns on trees, ice and boulders.

Origin
Weavile may be based on cats and weasels, but it also seems to draw inspiration from 鎌鼬 kamaitachi, weasel demons with sickles on their front legs. It can also be based on black cat demons from both Western and Asian culture that have various backgrounds but are all known for their trickery and cunning. Its appearance seems to be based on old Egyptian fashion, as it "wears" a headdress, collar, and earrings similar to what Egyptian deities wear. Its "eyeshadow" also resembles Egyptian makeup.
It is possible that Weavile has some influence from Bastet or Sekhmet in its design, being somewhat feline based, and having a very Egyptian style and garb. In addition, both these deities were famous for using their claws in warfare. It also bears slight resemble to Inca stone idols.
Name origin
Weavile may be a combination of weasel and vile.
Manyula is a combination of 魔 ma (demon), 潜入 sennyū (sneaking in), and 鼬 yū (weasel, an alternate reading of itachi). Nyu itself may be a combination of ニャー nya (the sound a cat makes) and 鼬 yū.
