This pokemon papercraft is Mawile (Kucheat), a dual-type Steel/Fairy Pokémon, and prior to Generation VI, a pure Steel-type Pokémon, based on the anime / game Pokemon, the paper model was created by Tenpepakura. There is another Mawile paper model on the site: Pokemon Mawile Papercraft Ver.1. While it is not known to evolve into or from any other Pokémon, it can Mega Evolve into Mega Mawile using the Mawilite.
Mawile is a short, bipedal Pokémon with a pale yellow body and black arms and feet. Its legs have a thick, fur-like covering resembling hakama or a skirt. Its most notable feature is a pair of large black jaws emerging from the back of its head. These jaws have an oval yellow spot on their top surface and contain ten pointed teeth - six on the top row and four on the bottom. While the jaws are said to actually be transformed steel horns, Mawile can articulate them at will, using them to bite enemies and chew through iron beams. It has red eyes and two black ear-like extensions on either side of its head.
Mega Mawile has a second set of jaws protruding from the back of its head, and both sets now have a spiky tuft of hair. It also seems to be able to control each jaw independently of each other. The ear-like extensions on its head are longer and have tips with two points. The fur on its legs is now magenta. It now has longer fur on its arms with magenta markings around its wrists.
Mawile is typically found in caves. It uses its non-threatening appearance to make foes underestimate it, then attacks with its giant jaws; when engaged in battle, Mawile usually has its back turned on the enemy to better use its jaws. [Source: Bulbapedia]
