This pokemon papercraft is Carvanha (Kibanha), a dual-type Water/Dark Pokémon, based on the anime / game Pokemon, the paper model was created by javier. Carvanha evolves into Sharpedo starting at level 30. There are 50 parts on 7 sheets of paper.
Carvanha has a round body covered in tiny, sharp denticles which create hydrodynamic advantages by reducing turbulence when swimming, as well as providing protection against physical attacks. The top half of Carvanha's roughly spherical body is blue, while the bottom half is red, with a four pointed yellow star-shaped marking below its mouth. Carvanha has two yellow dorsal fins above its eyes that resemble shark fins, and a matching pelvic fin on its belly. Its pectoral fins are also yellow. The caudal fin is composed of two red spines with a thin yellow membrane stretched between them.
Carvanha will eat practically any creature that they can sink their teeth into. This Pokémon lives in warm rivers with other Carvanha and where food is plentiful. This Pokémon is a pack hunter. Swarms of this Pokémon will attack virtually anything in the water with unmatched ferocity. Without the strength of numbers, however, this Pokémon becomes cowardly and shy.
Carvanha have jaws that are powerful enough to tear through a boat hull. Carvanha is also an exceptionally fast swimmer. It is also capable of using Special-based moves like Surf, Dark Pulse, Ice Beam, and AncientPower; however, Carvanha doesn't excel at those abilities. [Source: Bulbapedia]
